Problems solved by technology
[0002] Existing video conferencing systems generally include a video conferencing host and several different types of video conferencing slaves (peripherals). Different video codec parameters may be required for video transmission between these peripherals and the host. In the video conferencing system, the master and slave machines use fixed video codec parameters and transmission ports for transmission, which is not conducive to expansion
For example: Assume that host A and slave B are communicating with each other, and the codec in host A uses D-type codec parameters to encode and decode video data. If a slave C needs to be added to make a call at this time, However, the video codec parameters of the original slave C are different from the D-type codec parameters being used in the host A, so the same codec cannot be used at this time, and a new one needs to be re-enabled in the host A. The codec is used to process the video data for the slave C, so that every time a new slave is added, a new codec needs to be enabled in the master, but in the actual scene, the number of codecs of the master A Limited, once the number of codecs is insufficient, the connection will fail, and the scalability is poor

The invention discloses a video transmission control method and a video transmission system for a video conference. In the method, when establishing a video call between a conference host and a first conference slave, if it is judged that the conference host is currently conducting a conference with a second conference slave call, reconfigure the codecs of the conference host and the first conference slave according to the codec name, encoding grade information, and load type information used when the conference host communicates with the second conference slave . By implementing the embodiments of the present invention, the situation of connection failure caused by insufficient number of codecs can be solved, and the scalability of the conference video transmission system can be improved.
Description
technical field [0001] The invention relates to the technical field of video transmission, in particular to a video transmission control method and a video transmission system for a video conference. Background technique [0002] Existing video conference systems generally include a video conference host and several different types of video conference slaves (peripherals). These peripherals and the host may need to use different video codec parameters during video transmission. In the conventional video conference system, the master and slave use fixed video codec parameters and transmission ports for transmission, which is not conducive to expansion. For example: Suppose host A and slave B are in a device call, and the codec in host A uses D-type codec parameters to encode and decode video data. If a slave C needs to be added for the call at this time, The video codec parameters of the original slave C are different from the D-type codec parameters that are being used in t...
