Embodiment Construction

[0023] Please refer to Figure 1 to Figure 3 , a kind of real-time video communication transmission control method, described method is realized based on incomplete frame decoding, comprises the steps:

[0024] Step 10. The receiving end receives a frame of data sent by the sending end, and performs incomplete frame decoding control. The decoding control is to feedback the decoding effect and provide a basis for the encoding process control of the sending end. The specific method of the incomplete frame decoding control is as follows: : Each frame of data includes multiple Slices. When a frame of data is received, incomplete Slices are filtered to determine whether the frame is empty. If the frame is empty, the frame is discarded. If the frame is not empty, the frame is further judged to be complete. ;

[0025] If the frame is incomplete, judge whether the decoding key parameter is missing, if missing, discard it, if not missing, decode it; if the frame is complete, judge whe...

Abstract

The invention provides a real-time video communication transmission control method, which is realized by incomplete frame decoding, and comprises the following steps that: step 10, a receiving terminal receives data transmitted by a transmitting terminal, and carries out incomplete decoding frame; step 20, monitoring parameters are counted in the decoding process, and are fed back to the transmitting terminal; step 30, the transmitting terminal re-adjusts parameters of the encoding process according to the feedback result, encodes data to be transmitted and transmits the data to the receiving terminal by a network. The method provided by the invention starts from the real-time frame monitoring and feedback in the decoding process in a targeted way, the parameters of the encoding process at the transmitting terminal are adjusted to form a continuous negative feedback between a decoding terminal and an encoding terminal by feeding back the frame monitoring parameters, so that the network packet loss and jitter can be effectively reduced, and thus the video communications quickly adapts to the currently available bandwidth, the problems of video mosaic, screen color confusion, congestion and the like are solved, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of video communication, in particular to a real-time video communication transmission control method. Background technique [0002] At present, IP network technology is developing unprecedentedly. Under complex network conditions, real-time video communication applications are greatly challenged. Packet loss and jitter change randomly. Network resource sharing and control lead to insufficient bandwidth available for video communication. These factors will lead to serious The video mosaic, picture color confusion and freezing, are the deterioration of the user experience, which reduces the ease of use of real-time video communication applications. In order to solve the above problems, many real-time video communication systems currently appear to adopt an end-to-end control method. According to the packet loss rate fed back in the RFC3550 protocol, the encoding and transmission bit rate of the sending end are controlle...
