Claims
- 1. A television companion device (TCD) comprising:
a communication transceiver capable of receiving a signal, the signal having a plurality of streams split from a broadcast signal, each stream converted to at least one packet, the signal comprising multiplexed packets, each packet comprising an address, the transceiver identified by an assigned address, the transceiver adapted to determine, by comparing addresses in the packets with the assigned address, which packets are destined for the TCD, the transceiver thereby determining streams destined for the TCD; a selector that selects destined streams to be presented; and an output that presents the selected streams.
- 2. A device, as in claim 1, further comprising an input that sends one or more messages through the communication transceiver to a television (TV) transmitting the signal.
- 3. A device, as in claim 2, where the messages are any one or more of the following: a request for a control for a TV selector, a request for a web browser request, a request to a web browser to visit a web site, and an acknowledgment.
- 4. A device, as in claim 1, further comprising an input that sends one or more messages through the communication transceiver to another TCD.
- 5. A device, as in claim 1, where the output is different than a television (TV) output on a TV that transmits the signal.
- 6. A device, as in claim 1, further comprising a selector input that controls the selector.
- 7. A device, as in claim 1, further comprising a demultiplexer that demultiplexes one or more of the packets from the signal.
- 8. A device, as in claim 7, wherein the demultiplexer demultiplexes one or more of the packets based on the comparisons between the addresses in the packets with the assigned address.
- 9. A device, as in claim 1, where the streams include any one or more of the following: a video channel, an audio channel, a data channel, one or more graphical images, and one or more animated images.
- 10. A device, as in claim 1, where the signal is communicated over a communication link, and where the communication link is any one or more of the following: an infra red link, a radio link, a fiber optic link, and a coaxial link.
- 11. A device, as in claim 1, where the output includes any one or more of the following: a video output, an audio output, and a text output.
- 12. A device, as in claim 1, wherein each of the one or more addresses in the signal identify one of the following: the TCD, a subset of a group of TCDs, and all TCDs in a system.
- 13. A television companion device (TCD) comprising:
a communication interface capable of receiving a signal, the signal having a plurality of streams, each stream converted to at least one packet, the signal comprising multiplexed packets, each packet comprising an address; a demultiplexer that demultiplexes the packets; a profile subsystem that contains a profile of profile items in a database of information of interest to a viewer; a selector that determines packets destined for the TCD by comparing addresses in the packets with an assigned address that identifies the TCD, the selector thereby determining streams destined for the TCD, the selector additionally adapted to select the destined streams for presentation when one or more destined streams contain one or more profile items; and an output that presents one or more of the selected streams.
- 14. A device, as in claim 13, further comprising a processor subsystem comprising one or more processors which process any one or more of the following streams before the profile subsystem selects any streams: a video segment, an audio segment and data segment.
- 15. A device, as in claim 14, where one or more audio streams are processed by using speech recognition to generate a searchable transcript for key word searching.
- 16. A device, as in claim 14, that uses audio processing to determine the type of audio including any one or more of the following: speech, music, noise and sounds and using speaker identification processing to determine the identity of a particular speaker.
- 17. A device, as in claim 14, where one or more video streams are processed by using image processing to identify a searchable person, place, thing, action, or event.
- 18. A device, as in claim 14, where one or more data streams are processed by using text processing to generate a searchable hit list of one or more words.
- 19. A device, as in claim 14, where the processor subsystem generates identifiers from the processed streams, the identifiers used by the profile subsystem and the selector to control the selection.
- 20. A device, as in claim 14, where the processor subsystem generates identifiers from the processed streams, the identifiers being used to notify a user of the existence of one or more of the streams.
- 21. A device, as in claim 13, where the selector has a selector input that is any one or more of the following: mouse, keyboard, screen, and pointer.
- 22. A device, as in claim 13, wherein each of the one or more addresses in the signal identify one of the following: the TCD, a subset of a group of TCDs, and all TCDs in a system.
