Abstract

A method for audio and video communication, comprising establishing, by a telephony service, a first voice over IP (VoIP) session with a handset, establishing, by the telephony service, a second VoIP session with a display device that is wirelessly but not physically connected to the handset, separating, by the telephony service, an audio portion of a communication session from a video portion of the communication session, transmitting, by the telephony service, the separated audio portion to the handset using the first VoIP connection, and transmitting, by the telephony service, the separated video portion to the display device using the second VoIP connection.

Claims

1. A method for audio and video communication, comprising:

receiving, by a telephony service from a handset, a request to initiate or to answer a voice over IP (VoIP) phone call;

establishing, by the telephony service in response to said receiving, a first voice over VoIP session with the handset;

initiating, by the telephony service, a communication session with the handset;

establishing, by the telephony service, a second VoIP session with a display device that is wirelessly but not physically connected to the handset;

sharing, by the telephony service, the communication session with the display device;

separating, by the telephony service, an audio portion of the communication session from a video portion of the communication session;

transmitting, by the telephony service, the separated audio portion to the handset using the first VoIP connection;

transmitting, by the telephony service, the separated video portion to the display device using the second VoIP connection; and

synchronizing, by the telephony service, said transmitting of the audio portion with said transmitting of the video portion, based on time stamps received by the telephony service from each of the handset and the display device.

2. The method of claim 1 further comprising receiving, by the telephony service from the display device, a request to join the communication session, and wherein said establishing the second VoIP session and said sharing the communication session with the display device are performed in response to said receiving the request to join.

3. The method of claim 1 further comprising receiving, by the telephony service from the handset, a request to share the communication session with the display device, and wherein said establishing the second VoIP session and said sharing the communication session with the display device are performed in response to said receiving the request to share.

4. The method of claim 1 further comprising transmitting, by the telephony service, the audio portion of the communication session to the display device using the second VoIP connection.

5. The method of claim 1 further comprising transmitting, by the telephony service, the video portion of the communication session to the handset using the first VoIP connection.

6. The method of claim 1 further comprising synchronizing, by the display device via wireless communication with the handset, displaying of the video portion with playing of the audio portion by the handset.

7. The method of claim 1 further comprising synchronizing, by the handset via wireless communication with the display device, playing of the audio portion with displaying of the video portion by the display device.

8. The method of claim 1 further comprising:

establishing, by the telephony service, a third VoIP session with a second display device that is wirelessly but not physically connected to the handset; and

transmitting, by the telephony service, the video portion of the communication session to the second display device using the third VOIP connection.

9. The method of claim 8 further comprising recognizing, by the telephony service, that the wireless communication between the handset and the second display device is of better quality than the wireless communication between the handset and the display device, and wherein said establishing the third VoIP session is performed in response to said recognizing.

10. The method of claim 8 further comprising receiving, by the telephony service from the handset, a request to share the communication session with the second display device, and wherein said establishing the third VoIP session is performed in response to said receiving the request to share.

11. The method of claim 8 further comprising receiving, by the telephony service from the handset, a request to switch the communication session from the display device to the second display device, and wherein said establishing the third VoIP session is performed in response to said receiving the request to switch.
