Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] see figure 1 , Schematic diagram of the principle structure of the video communication system. The video communication system includes several video communication terminals, and the video communication terminals establish transmission connections through the network 11 or other communication channels. In order to better illustrate the frame rate adjustment method of the present invention, the present invention takes a visual communication process as an example. That is, the video communication terminal includes at least a video communication terminal 12 (referred to simply as a receiving end) for receiving video image data and a video communication terminal 13 (abbreviated as a transmitting end) for transmitting video image data. In the actual communication process, there is often two-way communication, that is, the receiving end is also the sending end of a...

Abstract

This invention discloses a frame rate regulation method for a video communication system. The system includes a sending end and a receiver. The method includes: several frame rate modes and the quantization way of the video image corresponding to each frame rate are set at each receiver and the sending end separately. 2, The receiver pre-sends the terminal required frame rate mode to the sending end, 3, The sending end encodes the video image according to said related quantization way of the frame rate mode to organize it to code streams and transmits them to said receiver which receives and recovers them to video images.

Description

technical field [0001] The invention relates to a video communication system, in particular to a method for adjusting frame frequency in the video communication system. Background technique [0002] With the development of network technology and video technology, video communication system has developed rapidly. For example, the video communication system is applied to services such as multi-video conferencing and video-on-demand (or interactive TV) to provide various services such as video conferencing, video telephony, distance learning and telemedicine. [0003] The video communication system at least includes several video communication terminals and a network connecting the video communication terminals. In the visual communication process, one of the video communication terminals is the sending end of the video image data, and usually at least one video communication terminal is the receiving end of the video image data. For the sending end, it mainly compresses and ...
