Abstract

A set-box (SBB) is advanced into a receptacle on the rear of a TV to add functionality to the TV. Digital video information is conveyed from the SUB to the TV using respective HDMI connectors on the SBB and TV that mechanically engage each other, whereas bi-directional control information is passed wirelessly between the SBB and TV.

Claims

1. A module for adding functionality to a component to be augmented, the module comprising:

a module housing for holding components facilitating the functionality; and

at least one high definition multimedia interface (HDMI) connector arrangement engaged with the housing and connectable to a complementary rigidly supported connector on the component for establishing a pathway for communication of digital video to the component to be augmented; and

at least one wireless transceiver on the housing and configured for bi-directional communication with a complementary transceiver on the component to augmented to facilitate handshaking communication therebetween.

2. The module of claim 1, wherein the component to be augmented is a TV.

3. The module of claim 2, wherein the functionality is video decoding functionality provided by the module but not by the TV.

4. The module of claim 1, wherein the handshaking communication includes device discovery communication.

5. The module of claim 1, wherein the handshaking communication includes metadata exchange.

6. The module of claim 1, wherein the wireless transceiver is an optical wireless transceiver.

7. The module of claim 1, wherein the wireless transceiver is a radiofrequency transceiver.

8. The module of claim 1, wherein the component is a TV and the module housing is disposable into a receptacle on a rear of the TV, the receptacle having an HDMI connector configured for mechanically engaging the HDMI connector arrangement on the module housing, the TV also including a wireless transceiver configured for communicating with the wireless transceiver of the module.

9. A system, comprising:

a TV defining a monitor, a rear opposed to the monitor, and a receptacle formed in the rear of the monitor, the TV having a digital video connector, the TV also including a wireless transceiver; and

a module housing for holding components facilitating audio-video functionality and disposable in the receptacle, the module housing including a digital video connector that mechanically engages the connector of the TV when the housing is moved into the receptacle, the module housing also supporting a wireless bidirectional transceiver configured for communicating with the transceiver of the TV.

10. The system of claim 9, wherein the digital video connectors are HDMI connectors.

11. The system of claim 10, wherein the HDMI connector of the module housing is rigidly supported by the housing and the HDMI connector of the TV is disposed in the receptacle, the HDMI connectors mechanically engaging each other when the module is advanced into the receptacle.

12. The system of claim 10, wherein the HDMI connector of the module housing is connected by an electrical cord to the housing.

13. The system of claim 9, wherein the functionality is video decoding functionality provided by the module but not by the TV.

14. The system of claim 9, wherein the wireless transceivers exchange device discovery communication.

15. The system of claim 9, wherein the wireless transceivers exchange metadata exchange.

16. The system of claim 9, wherein the wireless transceivers are optical wireless transceivers.

17. The system of claim 9, wherein the wireless transceivers are radiofrequency transceivers.

18. A method, comprising:

engaging a module with a TV, the module adding functionality to the TV;

using a mechanical connection to communicate digital video data from the module to the TV; and

using a wireless connection to communicate bidirectional control information between the module and TV.

19. The method of claim 18, wherein the mechanical connection is established using respective HDMI connectors on the module and TV.

20. The method of claim 18, comprising advancing the module into a receptacle on the rear of the TV.
