Abstract

A WiFi chipset is integrated into a TV chassis as are wireless audio-video signal antennas that feed the chipset and that are embedded in the display bezel. The TV processor causes signals from home network components received through the antennas and chipset to be displayed on the TV.

Claims

1. TV comprising:

a chassis;

a TV display on the chassis;

a wireless module supported by the chassis and configured to receive at least audio and video signals;

a TV processor communicating with the wireless module, the audio-video signals being presentable on the TV display under the control of the TV processor;

a TV tuner receiving TV signals from a TV signal source; and

at least one antenna element juxtaposed with a bezel surrounding the display and sending at least audio and video signals received from a home network to the wireless module.

2. The TV of claim 1, wherein the antenna element is shaped like an inverted letter “

F”

defining a stalk of disposed along a diagonal from a corner of the bezel.

3. The TV of claim 1, wherein the antenna element is a polarization diversity antenna disposed along a diagonal from a corner of the bezel.

4. The TV of claim 3, wherein the antenna element has a sawtooth shape.

5. The TV of claim 1, wherein the antenna element includes a meander line-diversity spacing antenna.

6. The TV of claim 5, comprising two meander-line like antenna elements parallel to each other and extending generally vertically from a top edge of the bezel to a top edge of the display.

7. The TV of claim 1, wherein the antenna element is molded into a backside of the bezel.

8. The TV of claim 1, wherein the antenna element is sandwiched between two pieces of the bezel.

9. The TV of claim 1, comprising at least one decorative trim line disposed along a diagonal from a bezel corner symmetrically with the antenna element.

10. Display apparatus, comprising:

wireless chipset in a display chassis;

video display on the chassis;

bezel bordering the display;

at least one wireless audio-video signal antenna element feeding data to the chipset, the antenna being disposed on or in the bezel; and

processor in the chassis causing signals from a component received through the antenna and chipset to be presented on the display.

11. The apparatus of claim 10, wherein the antenna element is shaped like an inverted letter “

F”

defining a stalk of disposed along a diagonal from a corner of the bezel.

12. The apparatus of claim 10, wherein the antenna element is a polarization diversity antenna disposed along a diagonal from a corner of the bezel.

13. The apparatus of claim 12, wherein the antenna element has a sawtooth shape.

14. The apparatus of claim 10, wherein the antenna element includes a meander line-diversity spacing antenna.

15. The apparatus of claim 14, comprising two meander-line like antenna elements parallel to each other and extending generally vertically from a top edge of the bezel to a top edge of the display.

16. The apparatus of claim 10, wherein the antenna element is molded into a backside of the bezel or sandwiched between two pieces of the bezel.

17. The apparatus of claim 10, comprising at least one decorative trim line disposed along a diagonal from a bezel corner symmetrically with the antenna element.

18. System for facilitating presentation on a TV in a home network audio-video content wirelessly received from the home network without requiring antenna wires extending outside the TV to receive the content, comprising:

means for displaying video content;

means for holding the means for displaying;

means for framing the means for displaying; and

antenna means embedded in the means for framing and configured for wirelessly receiving the audio-video content from the home network.

19. The system of claim 18, wherein the means for framing is a bezel and the antenna means includes at least one antenna element selected from the group of:

an inverted letter “

F”

defining a stalk of disposed along a diagonal from a corner of the bezel, a polarization diversity antenna disposed along a diagonal from a corner of the bezel, a meander line-diversity spacing antenna.

20. The system of claim 19, comprising at least one decorative trim line disposed along a diagonal from a bezel corner symmetrically with the antenna element.
