Method and apparatus for video conferencing
View Patent ↗A videoconferencing system couples to a network for providing videoconferencing services to a user. The videoconferencing session is controlled and initiated by a user in a manner consistent with establishing a conventional audio-only session. In one embodiment, an independently operable voice-only telephone handset couples to an audio and video communication device. The videoconferencing session is established by taking the telephone handset to an off-hook status and entering a dialed phone number sequence. The audio and video communication device retrieves a network address corresponding to the dialed phone number sequence and initiates a call sequence corresponding to the retrieved network address until the telephone handset goes into an on-hook status. The audio and video communication device further includes video interfaces for presenting the video aspects to the user.
1. An audio and video communication device, comprising:
a first interface for transmitting and receiving voice and image data over a network;
a second interface for compatibly coupling and interoperating with an independently operable voice-only telephone handset, said telephone handset inputting and outputting an audio portion of an audio and video communication session; and
a controller coupled with both said first and second interfaces, said controller configured to establish said audio and video communication session over one of a wide area or local area network in response to said telephone handset going off-hook, said controller further configured to, upon powering up, retrieve an assigned network address and upon receipt of the assigned network address, transmit the assigned network address to a remote database for correlation with an assigned phone number of the audio and video communication device stored in the remote database.
2. The audio and video communication device of claim 1 , further comprising a remote control interface coupled to said controller and configured to modify operation of said controller.
3. The audio and video communication device of claim 1 , further comprising:
a video input interface coupled to said controller and configured to interface with a video input device; and
a video output interface coupled to said controller and configured to interface with a video output device.
4. The audio and video communication device of claim 3 , further comprising the video input device coupled to said video input interface.
5. The audio and video communication device of claim 3 , further comprising the video output device coupled to said video output interface.
6. The audio and video communication device of claim 1 , wherein said second interface is configured to be compatible with a POTS interface for operably coupling with said telephone handset.
7. The audio and video communication device of claim 6 , wherein said controller is further configured as responsive to DTMF tones generated by said telephone handset.
8. The audio and video communication device of claim 1 , wherein said first interface is configured to be compatible with a voice-over-IP interface.
9. The audio and video communication device of claim 1 , wherein said independently operable voice-only telephone handset is integrated with said audio and video communication device.
10. A video conferencing system, comprising:
an independently operable voice-only telephone handset; and
an audio and video communication device, including a controller configured to support an audio channel with said telephone handset, a video channel, and an audio and video channel including an audio and video communication session with a network capable of coupling said videoconferencing system with a remote system, said controller further configured to establish said audio and video communication session over one of a wide area or local area network in response to said telephone handset going off-hook, said controller further configured to, upon powering up, retrieve an assigned network address and upon receipt of the assigned network address, transmit the assigned network address to a remote database for correlation with an assigned phone number of the audio and video communication device stored in the remote database.
11. The videoconferencing system of claim 10 , wherein said audio channel is configured according to a POTS interface.
12. The videoconferencing system of claim 11 , further comprising an off-hook detector configured to notify said controller and responsive to said telephone handset.
13. The videoconferencing system of claim 10 , wherein said audio and video channel is configured according to a voice-over-IP standard as supported by said network.
14. The videoconferencing system of claim 10 , wherein said video channel comprises:
a video input interface coupled to said controller and configured to interface with a video input device; and
a video output interface coupled to said controller and configured to interface with a video output device.
15. The videoconferencing system of claim 14 , further comprising the video input device coupled to said video input interface.
16. The videoconferencing system of claim 14 , further comprising the video output device coupled to said video output interface.
17. The videoconferencing system of claim 10 , wherein said audio and video channel is configured to communicate with a data network.
18. The videoconferencing system of claim 10 , wherein said independently operable voice-only telephone handset is a cordless telephone handset.
19. The videoconferencing system of claim 10 , wherein said independently operable voice-only telephone handset is configured to operate at signal levels compatible with said controller.
20. A method for establishing an audio and video communication session, comprising:
retrieving a first network address assigned to a first communication device from a network upon powering up said first communication device;
transmitting said first network address to a remote database upon receipt of said first network address for correlation with an assigned phone number of said first communication device stored in said remote database;
detecting a telephone handset going into an off-hook status and a dialed phone number sequence associated with a second communication device;
retrieving a second assigned network address from said remote database corresponding to said dialed phone number sequence associated with said second communication device; and
initiating a call sequence corresponding to said network address to establish said audio and video communication session over one of a wide area or local area network.
21. The method of claim 20 , wherein said retrieving includes accessing a remote database comprising said network address corresponding to said dialed phone number sequence.
22. The method of claim 20 , wherein said initiating a call sequence is compatible with one of H.323, SIP, and proprietary protocols.
23. The method of claim 20 , wherein said initiating a call sequence comprises:
opening both an audio channel for exchanging audio data with said telephone handset and a video channel for exchanging video data with video input and output devices when said telephone handset is off-hook;
opening an audio and video channel with a network; and
transceiving said audio data and said video data over said audio and video channel during said audio and video communication session.
