METHOD AND SYSTEM FOR TRANSMITTING AND RECEIVING DATA USING AN INFORMATION BROADCAST OVER FM CHANNEL (IBOF)
PROTOCOL
FIELD
[00011 The present invention relates to the field of multimedia communications. More particularly, the present invention relates to defining a set of rules for transmitting and receiving data using an information broadcast over FM channel (IBOF) protocol over an IBOF network.
BACKGROUND
[0002] Typically in a portable electronic device wireless data transfer and reception is required to share multimedia infonnation with a plurality of portable electronic devices. The wireless data transfer is achieved through a wireless media, for example, Bluetooth, infrared and radio waves. Further the wireless data transfer provides an option to the user of the portable electronic device to transmit audio signals, for example, music and speech to the plurality of portable electronic devices.
[0003] In the existing technique, the data is transmitted from the portable electronic device to the plurality of portable electronic devices using the FM channel. The data transmitted is received only if the plurality of electronic devices and the electronic device are supported by the same Original equipment manufacturer (OEM) irrespective of the model. In specific the data transmission is dependent on the OEM in the existing technique. Further in the existing technique, there may not be a mechanism to identify types of data type being broadcasted by the plurality of portable electronic devices. In the existing technique, the data transmitted from mobile phone is limited to a few meters. For example, the multimedia data transferred through Bluetooth requires the destination device to be within lOOmeters from the source device.
[0004] US Application Serial No. 2008/0070505 A1, entitled "Portable electronic device and a method in a portable electronic device", mentions that in the existing
2/38

technique when a user of a mobile phone is driving a vehicle, the user may not notice a message, a call and one or more notifications received In the mobile phone. Further hands free equipment is used to control the mobile phone without requiring the user to directly input information. However even though the hands free equipment is used by the user, the user still may not be able to see the infonnation displayed on the mobile phone. Further, in the existing technique the user may not be able to see the information displayed depending on where the mobile phone is placed and also the size of the text displayed.
[0005] US Application Serial No. 2007/0049197 A1, entitled "Control device for audio players", mentions that in the existing technique, when the user is listening to music from in built speakers of an audio player in the vehicle while driving, the user may not a notice the message, the call and the one or more notifications received in the mobile phone. Further in the existing technique the user may use a headphone to listen to the music, but this may be dangerous to the user as it is against the law and the probability of the user not been notified of the call are high. Moreover in the existing technique, if in case the user identifies the incoming call, then the user needs to pause the audio player manually before the conversation and also resume the audio player manually after the conversation. However the process of manually pausing and resuming the music played in the audio player is annoying to the user when the incoming call is received and also may result in a serious safety risk when driving the vehicle In high speeds. In light of the foregoing discussion there is a need for an efficient technique to operate the mobile phone and the audio player simultaneously while driving the vehicle.
[0006] In light of the foregoing discussion, there is a need for a method and system to solve the above mentioned problems.

[0060] It will be obvious to a person ordinarily skilled in the art, that the steps need not be perfonned in the same sequence. Further, such a person would appreciate any change in the execution of these steps.
[0061J FIG. 4 illustrates IBOF compliant logical channels for transmitting the datei by the IBOF compliant portable electronic device 105A to the IBOF compliant one or more portable electronic devices using IBOF protocol, in accordance with one embodiment of the invention.
[0062] The IBOF compliant portable electronic device 105A includes the FM transmitter 210 for transmitting the data to the one or more portable electronic devices. The data is transmitted through at least one of a Qutek information channel and a Normal Infonnation channel. Further any one among the two channels is active at any point of time. The Normal information channel is active default most of the times and is used for transmission of the data. Consider an example, if the data is placed in the Quick
17/38

information channel then the transmission of the data In the Normal infomnation channel is temfiinated automatically and the Nonnal information channel Is resumed only after the data is transfen^ed completely over the Quick infonnation channel.
[0063] The data placed in the Quick infonnation channel is given more prionty compared to the data placed in the Nomial infomnation <^annel and only one data type is transmitted in the Quick information channel at any point of time. Further the data transmission through the Nomnal infonnation channel is Inten^ipted automatically if the data is placed in the quick information channel.
[0064] Consider an example, wherein the user has a mobile phone as the IBOF transmitter 305 and a car audio device as the IBOF receiver 315A. The user of the mobile phone transmits an audio file to the car audio devk;e. The IBOF receiver 315A of the car audio device receives the audio file and plays the song transmitted by the Mobile Phone over FM. The lyrics of the song being played on the mobile phone are displayed on the display unit of the car audio device using the IBOF Nonnal Infonnation Channel. If a call is received on the mobile phone then the IBOF caller ID data type for the call is transmitted in the Quick information channel for immediate display of the caller ID on the car audio device. Further if the call is disconnected, then the nonnal infonnation channel resumes the transmission of lyrics to the car audio device.
[00651 The data is transmitted in the form of IBOF packets by the IBOF compliant portable electronic device 105A to the one or more pcntable electronic devices using IBOF protocol. The IBOF packet structure is generated and the IBOF packet structure includes a signature, a DID, a this_packet_number, a highe8tj}acket_number, a data and a ORG. The IBOF packet structure is listed below in the table in detail:

Field Size Remarks
Signature 8 bits Value « 11001100 in binary
UID 8 bits The UNIQUE IDENTIFIER which identifies the data_type canied by this IBOF packet.
this_packet_number 8 bits Contains the sequence number of this packet under this UID. It is a value in the range [ 1,
18/38

hlghest_packet_number]
highestj)acket_number 8 bits The last packet number under this UID.
DATA 20 bytes Payioad of the IBOF packet. The size has been calculated based on the IBOF Frame size (explained below).
CRC 8 bits CRC for this packet
[0066] Further as illustrated in the above table, each IBOF packet has the same size. The signature field in the IBOF structure is used by the FM receiver 240 of the IBOF compliant one or more portable electronics devices to determine the start of an IBOF packet when the FM receiver 240 is switched on. If the signature field in the IBOF packet structure is detected, then in the received bit stream, the same signature field should be detected after every IBOF packet size offeet. In one embodiment, the signature field in the IBOF packet structure is an algorithm for detecting the start of the packet in the event of transmission of data. The signature bits can also occur as data within the IBOF packet.
[0067] For example, the CRC polynomial used in the IBOF packet structure is
X^ + X^ + X+L
[0068] The UID table in the IBOF packet structure Is used for providing information of the current active channels. The UID table is also used for providing information about the data type transmitted. The IBOF receiver 315A of the IBOF compliant portable electronic device 10SB is switched ON and tuned to a frequency automatically to same as that of the FM transmitter 210. The IBOF receiver first tooks at the UID table to detennine the type of data transmitted by the FM transmitter 210. The UID table includes a version, a cun-ent_active_channel, a data_type_ver8k>n, a data_type, and the CRC. Further a change during the transmission of data is informed to the IBOF receiver by the change in the version of the UID table. The IBOF receiver continuously checks for the version change in the UID table. If a change occurs in the data type transmitted then the data_type_version field also changes.
19/38

[0069] Consider an example, the IBOF transmitter 305 transmits the GPS coordinate information in the Nomnal Information channel. If the GPS coordinate infomiation does not undergo a modification then the data_type_version for the GPS data type in the UID table remains unaltered. Further if a change in the GPS data occurs, then the data_type_version needs to be updated so that the IBOF receiver 31SA is notified to acquire the changes in the GPS data.
[0070] The UID table including a version, a current_active_channel, a data_type_version, a datajype, and the CRC are listed below in the table in detail:

Field Size Remarks
Version 3 bits Version number of this UID table
Cun"ent_Active 2 bit '00' - Reserved
_channel ■01'-QIC ACTIVE
'10'-NIC ACTIVE
'11' - No channel active ( No
transmission)
Data_type_version 3 bits Current version of the data type
Datajype 8 bits Data type UID.
If the value if OxFF, it means no data type is transmitted. This is used only when Cun'ent_Active _channel = '11'
CRC 8 bits 8 bit CRC
[0071J FIG. 5 illustrates IBOF data frame for the IBOF packets, in accordance with one embodiment of the invention.
[0072J The IBOF packets are transmitted by the IBOF compliant transmitter device 105A to the one or more IBOF compliant receiver devices using the RDS protocol. The IBOF data frame for the IBOF packets transmitted over the duration of 1 second with a data rate of 1187.5 bits per second are illustrated in frame 505 and frame 510. Further in every 26 bits of data transmitted for 1 second the 10 bits are used for enror detection and synchronizing time due to which the effective data rate available for IBOF is approximately 780 bits per second.
20/38

[0073] The data frame includes 632 bits of IBOF data and 320 bits of RDS check words. The data frame also includes an IBOF UID table of 4 bytes, an IBOF packet #1 of 25 bytes, an IBOF packet #2 of 25 bytes, an IBOF packet #3 of 25 bytes, and an IBOF packet #4 of 25 bytes.
[0074J If there is no data transmitted during the event, then the IBOF receiver needs to follow specific rules as listed below:
1. UID table needs to be transmitted with Data_type = OxFF and
Cun'ent_Active _channel = '11'.
2. UID of the IBOF packet header shall be set to OxFF.
3. The highest_packet_number and thls_packet_number fields shall be set to 0.
4. All bytes of the data field shall be set to OxFF.
5. Retaining a signature field value.
[0075] The UID table is transmitted in each of the frame 505 and the frame 510 due to which the repetition rate of the IBOF UID packets is once per second. If an error occurs in the UID table packets, then the IBOF receiver needs to wait until the next data frame is transmitted. Further if an en-or occurs in the IBOF packets then the IBOF receiver 315A can re-synchronize to the next IBOF packet using the signature field.

The application interface IBOF_Send () transmits the data on at least one of the quick Information channel and the normal information channel. Further a unique ID is sent as a response to the transmitter device application 31 OA by the IBOF transmitter 305. The IBOF transmitter 305 further updates the version of the UID table and schedules the data frame to be transmitted for the next cycle using the IBOF application interface IBOF_update. The IBOF transmitter
21/38

305 also updates the cun-ent content of an IBOF channel using Uie application Interface IBOF_Send (). The application interface IBOF_St(^ is used for stopping the transmission of the data between the transmitter device af^ltcation 310 and the IBOF transmitter 305. Further the DID table is transmitted to indicate that no data are transmitted through the channels. The IBOF receiver 315A is irtterfaced to the receiver device application 320A. The application interface IBOFjQuery is used for erKjuiring information about the data type transmitted in the IBOF channel. If there is no data type transmitted in the IBOF channel then the data_type parameter is set to OXFF. The application interface IBOF^Recleve is used for retrieving the data type transmitted by the IBOF transmitter to the IBOF receiver.
