Abstract

A television receiver system, comprising: a television receiver operable to receive broadcast video signals; a memory storing a communication client application; a processor, coupled to the memory and operable to execute the communication client application, wherein the communication client application is programmed so as when executed to allow a user to establish a video call with one or more other users via a packet-based communication network; a video buffer operable to buffer video data for display on a television screen; and selection means having a first input arranged to receive broadcast video data from the television receiver, a second input arranged to receive video call data from the communication client, an output connected to the video buffer, and a control input connected to the communication client, wherein the selection means is arranged to output the broadcast video data to the video buffer in the absence of a selection signal at the control input, and wherein the communication client is arranged to generate a selection signal to control the selection means to output the video call data to the video buffer responsive to receiving a command to establish a video call from the user.

Claims

1. A television receiver system, comprising:

a television receiver operable to receive broadcast video signals;

a memory storing a communication client application;

a processor, coupled to the memory and operable to execute the communication client application, wherein the communication client application is programmed so as when executed to allow a user to establish a video call with one or more other users via a packet-based communication network;

a video buffer operable to buffer video data for display on a television screen; and

selection means having a first input arranged to receive broadcast video data from the television receiver, a second input arranged to receive video call data from the communication client, an output connected to the video buffer, and a control input connected to the communication client,

wherein the selection means is arranged to output the broadcast video data to the video buffer in the absence of a selection signal at the control input, and wherein the communication client is arranged to generate a selection signal to control the selection means to output the video call data to the video buffer responsive to receiving a command to establish a video call from the user.

2. A television receiver system according to claim 1, wherein the communication client is arranged to connect the video call over the packet-based communication network responsive to receiving the command to establish the video call.

3. A television receiver system according to claim 1, wherein the communication client is further arranged to generate a selection signal to control the selection means to revert to the output of the broadcast video data to the video buffer responsive to the communication client receiving a command to terminate the video call.

4. A television receiver system according to claim 1, wherein the communication client is arranged to control the selection means to output the broadcast video data to the video buffer responsive to the communication client receiving a command to reject the video call and establish an audio call.

5. A television receiver system according to claim 1, wherein the command to establish a video call from the user input means is a command to initiate an outgoing video call.

6. A television receiver system according to claim 1, wherein the command to establish a video call from the user input means is a command to accept an incoming video call received at the communication client over the packet-based communication network.

7. A television receiver system according to claim 1, wherein the communication client application is arranged to generate a user interface for output on a television screen.

8. A television receiver system according to claim 7, wherein the communication client is arranged to generate a notification of the incoming video call on the user interface responsive to receiving the incoming video call.

9. A television receiver system according to claim 7, wherein the user interface comprises a list of one or more other users of the packet-based communication network associated with the user.

10. A television receiver system according to claim 1, further comprising a remote control unit comprising at least one wireless communication means arranged to transmit data to the processor, a control means coupled to the wireless communication means and configured to control the wireless communication means, and user input means coupled to the control means and arranged to receive input commands from the user and provide the input commands to the control means.

11. A television receiver system according to claim 10, wherein the command to establish a video call is received at the control means from the user input means, and transmitted to the communication client using the at least one wireless communication means.

12. A television receiver system according to claim 10, wherein the remote control unit further comprises a microphone coupled to the control means and arranged to receive audio signals from the user.

13. A television receiver system according to claim 12, wherein the microphone is retractable from the remote control unit, and the control means is arranged to generate the command to establish the video call responsive to the user retracting the microphone and transmit the command to establish the video call to the communication client using the at least one wireless communication means.

14. A television receiver system according to claim 10, wherein the at least one wireless communication means comprises at least one of a radio transmitter and an infra-red transmitter.

15. A television receiver system according to claim 1, wherein the communication client application is arranged to decode audio and video packets received at the processor over the packet-based communication network as audio and video data.

16. A television receiver system according to claim 1, wherein the communication client application is arranged to encode audio and video signals received at the processor as voice over internet protocol packets and video packets for transmission over the packet-based communication network.

17. A television receiver system according to claim 1, wherein the communication client application is programmed to allow the user to establish calls via a peer-to-peer connection in the packet based communication network.

18. A television receiver system according to claim 1, wherein the television receiver system comprises one of a television set and a set-top box arranged to connect to a television set.

19. A media appliance, comprising:

a video playback device operable to retrieve stored video data from a storage location;

a memory storing a communication client application;

a processor, coupled to the memory and operable to execute the communication client application, wherein the communication client application is programmed so as when executed to allow a user to establish a video call with one or more other users via a packet-based communication network;

a video buffer operable to buffer video data for display on a television screen; and

selection means having a first input arranged to receive stored video data from the video playback device, a second input arranged to receive video call data from the communication client, an output connected to the video buffer, and a control input connected to the communication client,

wherein the communication client is arranged to control the selection means to output the video call data to the video buffer responsive to the communication client receiving a command to establish a video call from the user.

20. A media appliance according to claim 19, wherein the media appliance comprises one of a video disc player arranged to connect to a television set, a personal video recorder arranged to connect to a television set, and a games console arranged to connect to a television set.

21. A method of controlling video signals in a television receiver system having a processor executing a communication client, comprising:

receiving broadcast video signals at a television receiver and providing broadcast video data from the television receiver to a first input of a selection means;
