Field of the Invention:
The present invention relates to a Set Top Box with Screen for hassle-free, cable free, single remote seamless TV viewing.
Background of the Invention:
There are still 100 million households in India who still don't possess a TV set. With time and socio-economic development, they will come to possess a low cost TV set. However, to view watch conditional access based TV broadcasts, the household would be forced to set top box. Thus, as per the current technology trends, a household must purchase TV set and a separate set top box to watch conditional access based TV broadcasts, thus incurring high cost.
Apart from the above, they are forced to operate two different devices i.e. the TV set and the set top box using two different remotes. There are additional wires which are required for connection for examples, there are two sets of power cables, cables are needed for interconnecting the set top box and the TV set, etc.
In the past, some companies have made attempts to solve the aforesaid problems by providing an integrated television cum set top box. One such product which is available in the market has the following configurations:

Referring to Figure 1, there is illustrated a block diagram of a Set Top Box with Screen(lOO) constructed in accordance with an embodiment of the invention. The Set Top Box with Screen comprises (100) a box-type structure (not specifically shown) defining a front panel (102), a back panel (104), a bottom panel (106), a top panel (not specifically shown) and side panels (not specifically shown) disposed between the front, back, bottom, and top panels. In an embodiment of the invention, the front panel comprises a screen (108), a power control button (110), an infra-red sensor (112), a power ON-OFF indicator (114) and a remote operation indicator (116). The power ON-OFF indicator (114) and a remote operation indicator (116) can be in the form of LEDs.
In an embodiment of the invention, the back, top, bottom and side panels have disposed thereupon elements selected from a group comprising (a) an AC power input port (118), (b) audio/video output ports (120); (c) a common interface (CI) slot (122); (d) a LNB input port (124); (e) speaker(s) (126); and / or (f) USB input port (128).
The Set Top Box with Screen (100) further comprises a first electronic sub-system (130) and a second electronic sub-system (132) accommodated within the box type structure. The first electronic sub-system (130) is adapted to receive command signals via the infra¬red sensor (112). The first electronic sub-system (130) is operably connected to the screen (108), the speaker(s) (126), which may be considered as the associated units. The first electronic sub-system (130) is further adapted to control operation of the one or more associated units on the basis of the command signal(s).
The second electronic sub-system (132) is adapted to receive broadcasted content from the LNB input port (124). The second electronic sub-system (132) is further adapted to receive

the command signal and process the broadcasted content in accordance with the command signal to generate output content. The second electronic sub-system (132) is further adapted to provide the output content to the first electronic sub-system (130) for output via the screen (108) and/or the speaker(s) (126).
In an embodiment of the invention, the AC power as received from the AC power input port (118) is first fed to the first electronic sub-system (130). The first electronic sub¬system (130) is adapted to provide rated power to the second electronic sub-system (132). In an embodiment of the invention, the first electronic sub-system (130) is adapted to control supply of the rated power to the second electronic sub-system (132) taking into consideration the command signal(s) thus received. In particular, the first electronic sub-system (130) is adapted to interrupt supply of a rated power to the second electronic sub-system (132), thereby completely switching OFF the second electronic sub-system (132); and supply the rated power to the second electronic sub-system (132), thereby bringing the second electronic sub-system (132) to an ON state.
In particular, the first electronic sub-system (130) comprises a power supply component (134), a television core component (136) and a memory component (138). The second electronic sub-system (132) on the other hand comprises a tuner component (140), a STB core component (142) and a memory component (144). The power supply component (134) as forming part of the first electronic sub-system (130) provides rated power to the second electronic sub-system (132).
In an embodiment of the invention, the first electronic sub-system (130) is further adapted to send simulated control signal to the second electronic sub-system (132) under predetermined conditions. In particular, the predetermined condition includes receipt of the command signal by the first electronic sub-system (130) and the second electronic sub-system (132) failing to perform a task associated with the command signal.
Referring to Figure 2, there is illustrated a more detailed block diagram of the Set Top Box with Screen (100) specifically showing more components of the first electronic sub-

system (130) and the second electronic sub-system (132). It can be seen that the first electronic sub-system (130) further comprises amplifiers (146).The amplifiers (146) may be operably connected to the television core component (136). In an embodiment of the invention, the second electronic sub-system (132) is adapted to receive a volume control signal, generate a volume setting adjustment command, and send the same to the first electronic sub-system (130). The volume setting adjustment command is specifically provided to the amplifiers (146) forming part of the first electronic sub-system (130). In particular, the STB core component (142) forming part of the second electronic sub-system (132) is adapted to generate a volume setting adjustment command, and send the same to the television core component (136), which in turn communicates the volume setting adjustment command to the amplifiers (146).
The first electronic sub-system (130) further comprises speaker driver(s) (148) that can be used for driving the speaker(s) (126). The speaker driver(s) (148) may be operably connected to the television core component (136).
The television core component is connected to the infra-red sensor (112) such that the television core component (136) receives an output of the infra-red sensor (112).
The first electronic sub-system (130) further comprises a first switch (150) which also receives the output of the infra-red sensor (112). The first switch (150) is controlled by the television core component (136) and can be brought to one of ON or OFF states. In one of the states of the first switch (150), the output of the infra-red sensor (112) is provided to the STB core component (142) while in the other state of the first switch (150), the output of the infra-red sensor (112) is not provided to the STB core component (142).
Apart from the above, the television core component (136) is provided with the ability to simulate a control signal which is equivalent to the output of the infra-red sensor (112) and send it under predefined conditions to the STB core component (142).

The first electronic sub-system (130) further comprises a second switch (152) which is connected to an output of the power supply component (134). The second switch (152) is also under the control of the television core component (136) and in particular, the second switch (152) is controlled by the television core component (136) and can be brought to one of ON or OFF states. Thus, by controlling the ON/OFF state of the second switch (152), the television core component (136) can control the supply of the rated power by the power supply component (134) to the second electronic sub-system (132).
The second electronic sub-system (132) further comprises a DC/DC unit (154) that receives the rated power from the power supply component (134) located in the first electronic sub-system (130) and supplies the suitable power to all components forming part of the second electronic sub-system (132). The second electronic sub-system (132) further comprises a low-noise block down converter (LNB) (156) which is also connected between the LNB input port (124) and the STB core component (142).
The first electronic sub-system (130) is connected to the second electronic sub-system (132) such that high definition multimedia information (HDMI) can be communicated by the second electronic sub-system (132) to the first electronic sub-system (130). Further, STB control commands are transmitted by the TV core component (136) to the STB core component (142). Furthermore, STB core component (142) communicates acknowledgement messages (GPIO0 (G), GPIOl (R), GPI02 (R), and GPI03(Y)) which are provided to the LEDs which function as the power ON-OFF indicator (114) and the remote operation indicator (116).The acknowledgement messages (GPIO0 (G), GPIOl (R), GPI02 (R), and GPI03(Y)) can be in either "0" state or in "1" state. The acknowledgement messages may be used for deriving additional functionalities, as will be described later.
Now referring to Figure 3, there is illustrated a more detailed block diagram of the second electronic sub-system (132). The STB core component (142) may be a component that can perform tasks such as decoding of MPEG -2/4 signals; decoding of DVB-S/S2 signals, decoding of H.265 signals, transmission of high definition multimedia information

(HDMI), implementation of conditional access, Automatic PAL/NTSC conversion, Various channel editing functions (favorite, move, lock, skip, delete, rename, find, sort), etc.
The second electronic sub-system (132) may comprise buffer (158) which may be connected between the STB core component (142) and the audio/video output ports (120) for buffering the information being transmitted by the STB core component (142) to the audio/video output ports (120).
The high definition multimedia information (HDMI) transmitted by second electronic sub-system (132) to the first electronic sub-system (130) may be routed through a HDMI output port (160) which may be contained in the second electronic sub-system (132). The HDMI output port (160) may be may be connected to the STB core component (142) via an electrostatic discharge protection device (162).
The second electronic sub-system (132) may comprise an over voltage protection (OVP) device (164) which may be connected to the input of the DC/DC unit (154). The over voltage protection (OVP) device (164) can thus protect the DC/DC unit (154) and the remaining components of the second electronic sub-system (132)when the voltage exceeds a preset level (for example, 12V).
Now referring to Figure 4, there is illustrated a block diagram showing the interconnection between the first electronic sub-system, the second electronic sub-system and the components disposed on the front panel and the interaction there between in accordance with an embodiment of the invention. The power control button (110) which is disposed on the front panel is operably connected to a first input port (GPI06) of the TV core component (136). The IR sensor (112) disposed on the front panel is connected to a second input port (IR In) of the TV core component (136) and to the first switch (150). An output of the first switch (150) is connected to a first input port (IR In) of the STB core component (142). The first switch (150) receives a control command from a first output port (GPI07) of the TV core component (136). A second output port (GPI05) of the TV

core component (136) is connected between the output of the first switch (150) and a first input port (IR In) of the STB core component (142). In an alternative embodiment, the second output port (GPI05) of the TV core component (136) may be connected to a second input port (GPI05) of the STB core component (142).
Since the television core component (136) is provided with the ability to simulate a control signal which is equivalent to the output of the infra-red sensor (112), the simulated control signal is sent by the TV core component (136) via the second output port (GPI05) of the TV core component (136) to the first input port (IR In) of the STB core component (142). In an alternative embodiment, the simulated control signal is sent by the TV core component (136) via the second output port (GPI05) of the TV core component (136) to a second input port (GPI05) of the STB core component (142).
The STB core component (142) is provided with four output ports (GPIO0 (G); GPIOl (R); GPI02 (R); and GPI03 (Y)) for sending acknowledgement messages. The four output ports (GPIO0 (G); GPIOl (R); GPI02 (R); and GPI03 (Y)) of the STB core component (142) are connected to the LEDs that function as the power ON-OFF indicator (114) and the remote operation indicator (116). Additionally, the four output ports (GPIO0 (G); GPIOl (R); GPI02 (R); and GPI03 (Y)) of the STB core component (142) are connected to four corresponding input ports (GPIOl; GPI02; GPI03; and GPI04) of the TV core component (136). Thus, the acknowledgement messages which are provided to the LEDs are also provided to the TV core component (136). Thus, input port GPIOl of the TV core component (136) receives inputs from the output port GPIO0 (G) of the STB core component (142) and input port GPI02 of the TV core component (136) receives inputs from the output port GPIOl (R) of the STB core component (142). In case status of GPI01=1 (or alternatively GPIO0 (G) = 1) and GPIO2=0 (or alternatively GPIOl (R) = 0), it indicates the STB core component (142) being in Active Mode. On the other hand, if the status of GPIOl =0 (or alternatively GPIO0 (G) = 0) and GPI02=1 (or alternatively GPIOl (R) = 1), it indicates the STB core component (142) being in Standby Mode. Similarly, input port GPI03 of the TV core component (136) receives inputs from the output port

GPI02 (R) of the STB core component (142) and input port GPI04 of the TV core component (136) receives inputs from the output port GPI03 (Y) of the STB core component (142). In case status of GPI03 =1 (or alternatively GPI02 (R) = 1) and GPI04 =0 (or alternatively GPI03 (Y) = 0), it indicates receipt of Remote IR command by the front panel and non receipt of Broadcaster mail (B-Mail) by the STB core component. On the other hand, if the status of GPIO3=0 (or alternatively GPI02 (R) = 0) and GPI04=1 (or alternatively GPI03 (Y) = 1), it indicates non receipt of Remote IR command by the front panel and receipt of Broadcaster mail (B-Mail) by the STB core component.
The second switch (152) which is connected to an output of the power supply component (134) is further connected to a third output port (GPI08) of the television core component (136). Thus, the TV core component (136) generates and supplies control commands for controlling of the second switch (152) via the third output port (GPI08).
While the Set Top Box with Screen functions in the similar manner as a conventional Set Top Box in terms of reception of the satellite signals and decoding of the signals (and hence, not being elaborated), the processes involved in some of the operations are unique. For instance, the Set Top Box with Screen implements unique process in the following operations:
• supplying power within the Set Top Box with Screen for optimum energy consumption; and
• changing volume.
For instance, the method of supplying power within the Set Top Box with Screen for optimum energy consumption may comprise: receiving, by a first electronic sub-system (130), command signal(s) via an infra-red sensor (112); controlling, by the first electronic sub-system (130), operation of one or more associated units on the basis of the command signal(s);receiving, by a second electronic sub-system (132), command signal(s) and broadcasted content; processing, by the second electronic sub-system (132), the broadcasted content in accordance with the command signal(s) to generate output content and providing the output content to the first electronic sub-system (130); and controlling,

by the first electronic sub-system (130), supply of a rated power to the second electronic sub-system (132) on the basis of the command signal(s).
In an embodiment of the invention, controlling the supply of the rated power to the second electronic sub-system (132) on the basis of the command signal(s) comprises: interrupting supply of the rated power to the second electronic sub-system (132), thereby completely switching OFF the second electronic sub-system (132); and supplying the rated power to the second electronic sub-system (132), thereby bringing the second electronic sub-system (132) to an ON state.
In an embodiment of the invention, since the command signals as received by the Set Top Box with Screen may be directed to the second electronic sub-system (132), and since there exists the possibility of the command signal is received by the first electronic sub-system (130) and NOT by the second electronic sub-system (132), the method further comprises sending, by the first electronic sub-system (130), a simulated control signal to the second electronic sub-system (132) under predetermined conditions.
In an embodiment of the invention, the predetermined condition includes receipt of a command signal by the first electronic sub-system (130) and the second electronic sub-system (132) failing to perform a task associated with the command signal thus received.
Since the Set Top Box with Screen comprises two electronic sub-systems i.e. the first electronic sub-system (130) and the second electronic sub-system (132), changing the volume as being output by the Set Top Box with Screen can be performed by either or both of the two electronic sub-systems. However, it has been observed that all the techniques for changing the volume are not optimized. It has been found that a preferred method for changing the volume may comprise of receiving, by the second electronic sub-system (132), a volume control signal; generating, by the second electronic sub-system (132), a volume setting adjustment command; sending, by the second electronic sub-system (132), the volume setting adjustment command same to the first electronic sub-system (130). The volume setting adjustment command is specifically provided to the amplifiers (146)

forming part of the first electronic sub-system (130). In particular, the STB core component (142) forming part of the second electronic sub-system (132) is adapted to generate a volume setting adjustment command, and send the same to the television core component (136), which in turn communicates the volume setting adjustment command to the amplifiers (146). In response to receiving the volume setting adjustment command, the amplifiers (146) may generate the corresponding voltages and supply the same to the speaker drivers (148).
In an embodiment of the invention, supplying power within the Set Top Box with Screen
for optimum energy consumption may be needed while performing any of the following
operations:
o bringing the Set Top Box with Screen from operation mode to standby mode;
o bringing the Set Top Box with Screen from active standby mode to operation mode;
o bringing the Set Top Box with Screen from passive standby mode to operation mode;
and o bringing the Set Top Box with Screen from Power OFF mode to Power ON mode.
Thus, the processes involved in these unique operations are elaborated in detail hereinafter.
Now referring to Figure 5 there is illustrated a flow chart of the process (200) involved in bringing the Set Top Box with Screen from operation mode to standby mode in accordance with an embodiment of the invention. Since, the Set Top Box with Screen has two components namely the TV core component and the STB core component, entire device has to enter into a standby mode. Also, it may be noted that it possible to enter into any of (a) passive standby mode; or (b) active standby mode. Thus, the Set Top Box with Screen has to enter into the standby mode in an effective manner.
The process involved in ensuring that the Set Top Box with Screen enters into the standby mode in an effective manner comprises the step of detecting whether the Set Top Box with Screen is in the ON condition (202). In case the Set Top Box with Screen is in ON condition, it is determined as to whether the TV core component is in ON condition (204)

and whether the STB core component is in ON condition (206). These steps of determining as to whether the TV core component is in ON condition (204) and whether the STB core component is in ON condition (206) can be performed in a manner independent of each other. Thus, these two steps (204 and 206) are shown as two independent branches of the process (200).
Once the STB core component is determined to be in ON condition (206), the STB core components determines whether a standby command has been received (208). In response to receiving the standby command, the STB core component disables output of the High Definition Multimedia Information to the TV core component (210). The STB core component also generates signals, in particular, the STB core component generates acknowledgement signals GPIO0 (G)=0 and GPIOl (R)=l. These acknowledgement signals are transmitted (210) to the TV core component. Thereafter, the STB core component enters into Active standby mode (212).
Once the TV core component is determined to be in ON condition (204), the TV core components determines (214, 216) whether a standby command has been received from the power control button (110) or the infra-red sensor (112). In response to determining by the TV core components that a standby command has NOT been received, the TV core component detects (218, 220) one or more of (a) cessation of receipt of the High Definition Multimedia Information, (b) status of one or more acknowledgement signals received from the STB core component. The one or more acknowledgement signals may be GPIO0 (G) (which is treated by the TV component as GPIOl), GPIOl (R) (which is treated by the TV core component as GPI02). In particular, the TV core component detects cessation of receipt of the High Definition Multimedia Information, the acknowledgement signal GPIOl's status being equal to 0 and the acknowledgement signal GPI02's status being equal to lwithin a predetermined time period. This predetermined time period may for example, be set as 1 second. In case all the conditions are satisfied, the TV core component is brought to standby mode (222). This results in the Set Top Box with Screen entering into active standby mode (224). If on the other hand, all the conditions are not satisfied, the

process loops back to the TV core components determining (214, 216) whether a standby command has been received from the power control button (110) or the infra-red sensor (112).
On the other hand, in response to determining by the TV core components that a standby command has been received, the TV core component detects whether the standby command has been received for a period equal to or in excess of a threshold value (226). By way of a non-limiting example, the threshold value can be 5 seconds. In case it is determined that the standby command has been received for a period equal to or in excess of a threshold value, the TV core component is brought to standby mode and the second switch is brought to OFF condition (228). Switching OFF of the second switch is performed by the TV core component in a manner as described above (i.e. the TV core component (136) generates and supplies control commands for controlling of the second switch (152) via the third output port (GPI08)). Thus, Set Top Box with Screen enters into passive standby mode (230).
In case it is determined that the standby command has been received for a period less than the threshold value, the TV core component detects (232) cessation of receipt of the High Definition Multimedia Information, the acknowledgement signal GPIOl's status being equal to 0 and the acknowledgement signal GPI02's status being equal to 1 within a predetermined time period. This predetermined time period may for example, be set as 1 second. In case all these conditions are met, the TV core component is brought to standby mode (222) which results in the Set Top Box with Screen entering into active standby mode (224).
On the other hand, if all the aforesaid conditions are NOT met, the process proceeds to bring the first switch to the OFF condition (using the GPI07 Command as generated by the TV core component) and to release simulated standby command by the TV core component to the STB core component (using the GPI05). Thereafter, the first switch is brought to ON condition (using the GPI07 Command) (234).

The aforesaid process ensures that when the STB core component is in standby mode, the TV core component shall also enter into standby mode. The aforesaid process also ensures that before the TV enters standby mode (in response to receiving a command), the STB core component enters into standby mode.
The process also takes care of fault condition such as the TV core component missing a standby command as provided via a remote control unit, but which standby command is detected by the STB core component. The process also takes care of fault condition wherein STB core component missing the standby command as provided via the remote control unit or via the power control button, since the TV core component generates and releases the simulated standby command to the STB core component (using the GPI05?). This therefore ensures that the STB enters into an active standby mode.
It can be furthermore observed that the process ensures that under certain conditions the Set Top Box with Screen enters into passive standby mode while under certain other conditions, the Set Top Box with Screen enters into Active standby mode.
In an embodiment of the invention, the aforesaid mechanism of bringing the STB core component to standby mode is attempted for a predetermined time period, which for example may be 5 seconds. If the STB core component could not be brought active standby mode despite following the aforesaid mechanism (i.e. bringing the first switch to the OFF condition, releasing a simulated standby command by the TV core component to the STB core component (using the GPI05) and bringing the first switch to ON condition), an error "failed to bring the STB to standby condition" can be detected (236).
Now referring to Figure 6, there is illustrated a flow chart (300) of a process involved in bringing the Set Top Box with Screen from active standby mode to operation mode in accordance with an embodiment of the invention. The process involved in bringing the Set Top Box with Screen from active standby mode to operation mode comprises the step of detecting whether the Set Top Box with Screen is in the Active Standby mode (302). In case the Set Top Box with Screen is in Active Standby mode, it is determined as to

whether the TV core component is in standby condition (304) and whether the STB core component is in active standby condition (306). These steps of determining as to whether the TV core component is in standby condition (304) and whether the STB core component is in active standby condition (306) can be performed in a manner independent of each other. Thus, these two steps (304 and 306) are shown as two independent branches of the process (300).
Once the STB core component is determined to be in active standby condition (306), the STB core components determines whether a power ON command has been received (308). In response to receiving the power ON command, the STB core component outputs the High Definition Multimedia Information to the TV core component. The STB core component also generates acknowledgement signals GPIO0 (G) =1 and GPIOl (R) =0. These acknowledgement signals together with the High Definition Multimedia Information are transmitted (310) to the TV core component. Thereafter, the STB core component enters into operation mode.
Once the TV core component is determined to be in standby condition (304), the TV core components determines (312, 314) whether a Power ON command has been received from the power control button (110) or the infra-red sensor (112). In response to determining by the TV core components that a Power ON command has NOT been received, the TV core component detects status of the acknowledgement signals GPIO0 (G) (which is treated by the TV component as GPIOl), GPIOl (R) (which is treated by the TV core component as GPI02) as received from the STB core component. In particular, within a predetermined time period (which may for example, be set as 1 second) the acknowledgement signal GPIOl's status being equal to 0 and the acknowledgement signal GPI02's status being equal to Ois checked. In case both the conditions are NOT satisfied, the process loops back to the TV core components determining (312, 314) whether a Power ON command has been received from the power control button (110) or the infra-red sensor (112).
On the other hand, if either of the aforesaid conditions is satisfied, the TV core component brings the first switch to the OFF condition (using the GPI07 Command as generated by

the TV core component) and releases the simulated standby to the STB core component (using the GPI05). Thereafter, the first switch is brought to ON condition (using the GPI07 Command) (320).
In response to determining by the TV core components that a Power ON command has been received, all the components of the first electronic sub-system are provided power (322). Thereafter, it is determined (324) as to whether the high definition multimedia information is received from the STB core component. Further the acknowledgement signal GPIOl's status being equal to 1 is checked. This check may be performed after expiry of a threshold time period (for example 3 to 10 seconds). In case both the conditions are met, the Set Top Box with Screen is brought into power ON state (326). If however, both the conditions not satisfied, the TV core component brings the first switch to the OFF condition (using the GPI07 Command as generated by the TV core component) and releases the simulated power ON command to the STB core component (using the GPI05). Thereafter, the first switch is brought to ON condition (using the GPI07 Command) (328).
In an embodiment of the invention, the aforesaid mechanism of bringing the STB core component to operation mode is attempted for a predetermined time period, which for example may be 60 seconds. If the STB core component could not be powered up despite bringing the first switch to the OFF condition, releasing the simulated power ON command by the TV core component to the STB core component (using the GPI05) and bringing the first switch to ON condition, an error "failed to boot UP STB" can be detected (330).
It may be noted that when the TV enters into power ON mode after receiving the command, the STB shall also enter power ON mode. However, if the STB missed the command, the TV core component will simulate a power ON command and provide the same to the STB core component to make sure that the STB enters into power ON mode.
Now referring to Figure 7, there is illustrated a flow chart (400) of a process involved in bringing the Set Top Box with Screen from passive standby mode to operation mode in accordance with an embodiment of the invention. The process involved in bringing the Set

Top Box with Screen from passive standby mode to operation mode comprises the step of detecting whether the Set Top Box with Screen is in the Passive Standby mode (402). In case the Set Top Box with Screen is in Passive Standby mode, it is determined as to whether the TV core component is in standby condition (404) and whether the STB core component is in Power OFF (406). These steps of determining as to whether the TV core component is in standby condition (404) and whether the STB core component is in OFF condition (406) can be performed in a manner independent of each other. Thus, these two steps (404 and 406) are shown as two independent branches of the process (400).
Once the TV core component is determined to be in standby condition (404), the TV core components determines (408, 410) whether a Power ON command has been received from the power control button (110) or the infra-red sensor (112). In response to determining by the TV core components that a Power ON command has NOT been received, the TV core component keeps the second switch in the OFF condition (428) and hence, power is not supplied to the second electronic sub-system. On the other hand, in response to determining by the TV core components that a Power ON command has been received, the TV core component brings the second switch to ON condition (412) and waits for receipt of High Definition Multimedia Information and the acknowledgement message(s) from the STB core component. Once the second switch is brought to ON condition, power is supplied to the second electronic sub-system, which results in the STB core component being switched ON (414).Thereafter, the STB core component outputs the High Definition Multimedia Information to the TV core component. The STB core component also generates acknowledgement signals GPIO0 (G) =1 and GPIOl (R) =0. These acknowledgement signals together with the High Definition Multimedia Information are transmitted (416) to the TV core component. Thereafter, the STB core component enters into operation mode.
After bringing the second switch to ON condition (412), the TV core component detects receipt of High Definition Multimedia Information. Further the acknowledgement signal GPIOl's status being equal to 1 is checked. This check may be performed after expiry of a

threshold time period (for example 5 to 15 seconds). If neither of the condition is satisfied, the TV core component brings the first switch to the OFF condition (using the GPI07 Command as generated by the TV core component) and releases the simulated power ON command to the STB core component (using the GPI05). Thereafter, the first switch is brought to ON condition (using the GPI07 Command) (420). On the other hand, if either of the condition is satisfied, the Set Top Box with Screen is brought to operational mode (422).
In an embodiment of the invention, the aforesaid mechanism of bringing the STB core component to operation mode is attempted for a predetermined time period, which for example may be 60 seconds. If the STB core component could not be powered up despite bringing the first switch to the OFF condition, releasing the simulated power ON command by the TV core component to the STB core component (using the GPI05) and bringing the first switch to ON condition, an error "failed to boot UP STB" can be detected (424). It may also be noted that if at step 410 a Power ON command has NOT been received from the power control button (110) or the infra-red sensor (112), the power to STB core component can be kept in OFF condition using the second switch (154) and the GPI08 command (426).
It may be noted that when power to the Set Top Box with Screen is switched from OFF to ON condition (such as when a status of the Set Top Box with Screen changes from NOT receiving AC input to receiving AC input), it is possible to bring the Set Top Box with Screen to any of the following options namely: active standby mode, and operational mode. Now referring to Figure 8 there is illustrated a flow chart of the process (500) involved in bringing the Set Top Box with Screen from Power OFF mode to Power ON mode in accordance with an embodiment of the invention. The process comprises switching ON the power supply to the first electronic sub-system and switching the second switch to ON condition to enable flow of power to the second electronic sub-system (502). Therefore, the STB core component starts up (504) and outputs (506) the High Definition Multimedia Information to the TV core component. The STB core component also

generates acknowledgement signals GPIOO (G) =1 and GPIOl (R) =0. These acknowledgement signals together with the High Definition Multimedia Information are transmitted (506) to the TV core component. Thus, the STB core component enters into operation mode.
In response to switching ON the power supply to the first electronic sub-system, the TV core component checks for default setting (as may be set by the user or during the time of manufacturing) (508). In case there is no default setting, the Set Top Box with Screen comes automatically to active standby mode (510). On the other hand, if the default setting is present, the TV core component checks for receipt of High Definition Multimedia Information. . Further the acknowledgement signal GPIOl's status being equal to 1 is checked. This check may be performed after expiry of a threshold time period (for example 5 to 15 seconds). In response to receiving the High Definition Multimedia Information or the acknowledgement signal GPIOl's status being equal to 1, the Set Top Box with Screen is brought to operational state (516) i.e. where the first electronic sub¬system as well as the second electronic sub-system are in operational state and the Set Top Box with Screen is rendering the content as provided by the STB core component.
On the other hand, if it determined that both the conditions are not satisfied, the TV core component brings the first switch to the OFF condition (using the GPI07 Command as generated by the TV core component) and releases the simulated power ON command to the STB core component (using the GPI05). Thereafter, the first switch is brought to ON condition (using the GPI07 Command) (518).
In an embodiment of the invention, the aforesaid mechanism of bringing the STB core component to operation mode is attempted for a predetermined time period, which for example may be 60 seconds. If the STB core component could not be powered up despite bringing the first switch to the OFF condition, releasing the simulated power ON command by the TV core component to the STB core component (using the GPI05) and bringing the first switch to ON condition, an error "failed to boot UP STB" can be detected (520).

Now referring to Figure 9, there is illustrated a flow chart of a process (600) involved while changing a channel in accordance with an embodiment of the invention. The process comprises monitoring for reception of signal from the infra-red sensor (602). Thereafter, it is determined as to whether the signal thus received pertains to channel change (604). In case the signal thus received pertains to channel change, the STB core component directs the tuner to tune in an specific L band (606); the STB core component de-multiplexes, decodes the signal as received from the tuner (608); and changes the channel (610). Thereafter, the STB core component checks with the conditional access component for the channel authorization (612). In case the user is authorized to view the channel, audio-video component of the new channel is provided as the High Definition Multimedia Information (614) while in the absence of authorization to view the channel, a suitable message is provided (616) as the High Definition Multimedia Information.
Now referring to Figure 10, there is illustrated a flow chart of a process (700) involved while changing volume in accordance with an embodiment of the invention. The process comprises monitoring for reception of signal from the infra-red sensor (702). Thereafter, it is determined as to whether the signal thus received pertains to volume change (704). In case the signal thus received pertains to volume change, the STB core component directs the TV core component to change the volume (706, 708). The STB core component also generates suitable High Definition Multimedia Information indicating the changes the speaker volume and provides the same to the TV core component thereby rendering a graphical representation for feedback to the user (710).
While certain present preferred embodiments of the invention have been illustrated and described herein, it is to be understood that the invention is not limited thereto. Clearly, the invention may be otherwise variously embodied, and practiced.
