Abstract

The invention discloses a communication method and system based on a videophone terminal and a videophone terminal. The method comprises: in the video call process of the videophone terminal, the host computer performs video coding on the data containing the computer screen information to obtain the video coded data of the computer screen information; the first SIP videophone terminal receives the computer screen information Video coding data, and the video input source data sent to the second SIP videophone, the video data output by the camera unit, is switched to the video coding data of the received computer screen information; the second SIP videophone terminal receives the computer The video encoding data of the screen information is output and displayed, and the first SIP videophone terminal continues to output and display the video call data of the second SIP videophone terminal. Through the technical solution provided by the invention, the existing SIP videophone terminal is used to realize the sharing of computer screen information while performing video calls.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication method and system based on a videophone terminal and a videophone terminal. Background technique [0002] IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is a multimedia service subsystem supporting IP proposed by 3GPP. One of the core features of the IMS is that users can use a Session Initiation Protocol (Session Initiation Protocol, SIP) videophone terminal, and use the SIP videophone terminal to make video calls through broadband access. However, through the SIP videophone terminal, both calling parties can only conduct video calls, and cannot transmit computer screen information. [0003] Another solution that can transmit computer screen information uses a dedicated video conferencing terminal to conduct video calls and transmit computer screen information at the same time. However, this kind of dedicated video conferencing terminal requires both terminals...
