Parameter negotiation method in video communication, device and video communication terminal

Abstract

The invention discloses a parameter negotiation method in video communication, a device and a video communication terminal. the method comprises a video transmitting capability list of a video communication calling terminal and a video communication receiving capability list of the video communication calling terminal are received by a video communication called terminal, wherein the video transmitting capability list and the video receiving capability list are transmitted by a video communication calling terminal; video transmitting parameters of the video communication calling terminal are found in the video transmitting capability list, wherein the video transmitting parameters of the video communication calling terminal are matched with the video receiving capability of the video communication called terminal. Video receiving parameters of the video communication calling terminal are found in the video communication receiving capability list, wherein the video receiving parameters of the video communication calling terminal are matched with the video transmitting capability of the video communication called terminal. The video transmitting parameters and the video receiving parameters which are found are fed back to the video communication calling terminal. After the condition that video parameters are received by the video communication calling terminal is confirmed, video streaming is mutually transmitted by the video communication called terminal and the video communication calling terminal through video parameters after being negotiated. The parameter negotiation method in video communication, the device and the video communication terminal can improve video communication quality through asymmetric negotiation.

Description

technical field [0001] The present invention relates to the technical field of video communication, in particular, to a parameter negotiation method and device in video communication, and a video communication terminal. Background technique [0002] The development of the mobile Internet has promoted the growth of the smart terminal industry chain, and smart phones and tablet computers have become hot spots in the terminal market. The introduction of new operating systems and the improvement of chip processing performance have enabled various screen terminals to have the ability to support the development of video communication functions. Operators, terminal developers, and Internet manufacturers have begun to develop and launch point-to-point video communication with Internet or 3G Functional products, for example, from Face time on IPhone4 to various telepresence products, it can be seen that the application of video communication is becoming more and more extensive.

Problems solved by technology

However, with the increase of terminal types and the development of codec technology, terminals with large screen sizes and different codec capabilities often perform video communication with each other, which will lead to terminals with good performance must use older codec technology and Video communication with an image that is much lower than the resolution of its display screen, resulting in lower image quality for at least one party of the video communication, resulting in a poor user experience
