TELEVISION OPERATIVE TO DOWNLOAD NEW FUNCTIONAL
APPLICATIONS VIA AN EXTERNAL SOFTWARE MODULE AND TO
EXECUTE THE SAME WITHOUT ADDITIONAL HARDWARE

BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This application relates generally to a television that can operate in accordance
with new functional application software. More particularly, this application is directed
to a television that can download new functional application software through a
removable, externally-connected software module and can operate the new functional
application software as a new television feature without the need to connect an additional
hardware device or additional hardware devices to the television.
2. Description of the Related Art
[0002] From the early days of television and even through today, television stations
broadcast television programs as analog signals and television sets receive the analog
signals via television antennas and transduce the received analog signals into viewable,
continuous moving pictures with audible sound such as voice synchronized to the moving
pictures. As television technology progressed, accessory devices were developed that
connected to the television set to enhance the functionality of the television set. For
example, a video cassette recorder, commonly known as a VCR, could be purchased as a
separate hardware device and connected to the television set in order to record viewer-
selected broadcasted television programs.
[0003] As progress in the television technology continued, many modern television sets
today include computer-like capabilities. These modern television sets include high
performance microprocessors that run on a dedicated operating system such as Linux
(which is an operating system originally created by Linus Torvalds with the assistance of
developers around the world under the GNU General Public License and the source code
1

of this operating system is freely available to anyone). Such computer capabilities
enhance the functionality of the television set. For example, Yahoo (a registered
trademark of Yahoo! Inc. of Sunnyvale, CA) Widgets can be downloaded from the
Internet to television sets with computer-like capabilities for display thereon.
[0004] Additionally, television sets with computer-like capabilities usually have
firmware stored in a non-volatile memory. From time to time, this firmware might
require updating. A USB (universal serial bus) memory device stored with updated
firmware can be inserted in a USB port on the television set so that the updated firmware
can be downloaded to the non-volatile memory.
[0005] It would be beneficial to provide a television that can be enhanced in
functionality without connecting additional, separate hardware devices to the television.
It would also be advantageous to provide a television that can be connected to a
removable external storage device containing television-enhancement software for
downloading so that the television would have enhanced functionality without the need
for connecting additional or separate hardware devices. The present invention provides
these benefits and advantages.

DETAILED DESCRIPTION OF THE INVENTION
[0021] A television 10 of the present invention is generally introduced in Figures 1-3
and includes a control section 12, an interface 14 and an external software module 16.
The control section 12 includes a processor 18 and an internal memory 20 that is in
communication with the processor 18. As is commonly known in the art, the internal
memory 20 stores original program instructions that are used by the processor 18 so that
the processor 18 can operate the television 10 in accordance with the original program
instructions. The interface 14 is accessible exteriorly of the television 10 and is in
communication with the control section 12. The interface 14, the processor 18 and the
internal memory 20 are in communication with each other through a conventional bus 21.
[0022] With reference to Figures 1-3, the external software module 16 is connectable to
the interface 14 and stores additional application program instructions. The additional
application program instructions are downloadable to the control section 12 when the
external software module 16 is connected to the interface 14. The downloaded additional
4

application program instructions enable the television 10 to function in a manner
differently than any of the original program instructions.
[0023] As represented in Figure 1, a first embodiment of the television 10 of the present
invention illustrates the external software module 16 removably connected (drawn in
solid lines) to the interface 14 of the television 10 and removed therefrom (drawn in
phantom). Although not by way of limitation but by example only, the external software
module 16 is depicted as a universal serial bus (USB) memory device such as a USB hard
drive or a USB stick and, therefore, the interface 14 would be a universal serial bus
(USB) receptacle. Furthermore, a skilled artisan would appreciate that the external
software module 16 can also be a hard disk drive, a floppy disk drive device, a ram disk,
a digital video device (DVD) drive, flash memory, a zip drive, a rotating optical storage
device such as a compact disk drive (CD) and a digital video device (DVD) drive or any
other type of external software storage device known in the art or hereinafter developed.
Furthermore, it is preferred that the interface 14 be either a high definition multimedia
interface (HDMI), the universal serial bus (USB) port or IEEE 1394.
[0024] In Figure 2, a second embodiment of a television 210 of the present invention
illustrates the external software module 16 removably connected to the television 210 by
a conventional cable 22 with a conventional connector 24 that plugs into the interface 14
of the television 210. By way of example only, the conventional connector 24 might be a
USB connector and, therefore, the interface 14 would be a compatible USB receptacle.
[0025] With regard to Figure 3, a third embodiment of a television 310 of the present
invention depicts the external software module 16 connectable to the television 310 in a
wireless manner as illustrated by the line of dots 26 interconnecting the interface 14 and
the external software module 16. By way of example only, the interface 14 and the
external software module 16 can communicate with each other via conventional and
compatible infra red communication devices, radio wave communication devices or any
other wireless communication devices known in the art or hereinafter developed.
[0026] For simplicity of explanation, only the television 10 of present invention is
hereinafter discussed although one skilled in the art would appreciate that the principles
discussed hereafter apply to the television 210 and the television 310. The downloaded
5

additional application program instructions enable the television 10 to emulate a
television-compatible hardware device without any need for additional hardware.
Although not by way of limitation but by example only, the television-compatible
hardware device might be a video/audio recorder, a slide show presentation device, a
video game player device or an audio amplifier. Thus, the downloaded additional
application program instructions can enable the television 10 to function as video/audio
recorder, a slide show presentation device, a video game player device or an audio
amplifier without the need for installing a separate hardware device or devices that, in the
past, have provided a television with these additional functions. Furthermore, by way of
example only and not by way of limitation, the downloaded additional application
program instructions might enable the television to operate a conventional widget without
the television 10 having Internet capabilities.
[0027] A skilled artisan would appreciate that, for the video/audio recorder, once the
external software module 16 is detected, the external software module 16 would populate
the option menus with the capability to record the audio and video and thereafter play
back the same at a later time. For the slide show presentation device, a slide show on the
external software module 16 might be prepared as a Power Point (a registered trademark
of Microsoft Corporation of Redmond, Washington) presentation and, after being
downloaded to the control section 12, the television 10 would automatically perform the
slide show.
[0028] It is preferred that the processor 18 is a high performance microprocessor.
Preferably, the high performance microprocessor is operative to run a Linux operating
system. Furthermore, it is preferred that the external software module 16 stores a
memory file system. Preferably, the external software module 16 contains loader scripts.
It is further preferred that the internal memory 20 stores scanning program instructions.
These scanning program instructions scan the memory file system of the external
software module 16 for the loader scripts when the external software module 16 is
connected to the interface 14. As is known in the art, when the loader scripts are located
by the control section 12, the loader scripts are used to add the additional application
program instructions to the control section 12.
6

[0029] One of ordinary skill in the art would appreciate that the internal memory 20 is
random access memory. Such random access memory might be dynamic random access
memory, static random access memory or flash memory.
[0030] Other components of the televisions 10, 210 and 310 such as a tuner, a display
screen and the like are well known in the art and are not shown here in order to focus
upon the aspects of the present invention. Therefore, no further discussion of these well-
know television components are deemed necessary for explanation and understanding of
the present invention.
[0031] Another embodiment of the present invention is a method for adding new
application program instructions to a television and is discussed with reference to Figure
4. Step SI provides the television 10 that has the control section 12 capable of detecting
the presence of the external software module 16 when the external software module 16 is
connected to the television 10. Step S2 determines whether the external software module
16 is detected. If not, the method ends. If the external software module 16 is detected in
Step S3, the method proceeds to Step S3. In Step S3, the memory file of the external
software module 16 is scanned for loader scripts and new application program
instructions. In Step S4, it is determined whether the loader scripts and the new
application program instructions are present on the external software module 16. If not,
the method ends. If it is determined that the loader scripts and the new application
program instructions are present on the external software module 16, Step S5 downloads
the loader scripts and the new application program instructions to the television 10 so that
the television 10 is now operable, when desired by a viewer, to run the new application
program instructions.
[0032] Although the present invention has been described in considerable detail with
reference to certain embodiments thereof, other embodiments are possible. Other
embodiments will become apparent to the ordinarily skilled artisan once instructed
