Embodiment 1
[0017] An embodiment of the present invention provides a distributed video processing method. figure 1 is a flowchart of a distributed video processing method according to an embodiment of the present invention, such as figure 1 As shown, the method includes:
[0018] Step S102, the MCU determines that the terminal supports distributed video processing capability;
[0019] In step S104, the MCU sends the multi-screen attribute information of the current conference to the terminal, so that the terminal synthesizes a multi-screen image according to the multi-screen attribute information.
[0020] In this embodiment, the terminal can support distributed video processing capabilities. In this case, the MCU does not need to synthesize multiple pictures, but only needs to send the multi-picture attribute information to the terminal, and the terminal can implement multiple pictures. Synthesis, thereby reducing the load on the MCU.
[0021] Wherein, after step S104, the terminal ca...
Embodiment 2
[0030] The technical problem to be solved in this embodiment is: in the related art, the media of the video conferencing system is processed centrally by the MCU, which inevitably faces the high load of MCU equipment processing (especially in the case of multi-screen and mixed-capability conferences), and the high bandwidth of network transmission. And other problems, resulting in the high cost of MCU, the integration level is not easy to improve and other defects. This embodiment provides a method for distributed media distributed processing, which distributes the composite processing of multiple images to each participating terminal, thereby greatly reducing the power consumption of the MCU in video processing, and reducing the power consumption of this part It is borne by each participating terminal, and the MCU pays more attention to signaling and process control. At the same time, for the sake of compatibility, when the MCU communicates with a terminal that does not suppo...
Embodiment 3
[0077] figure 2 It is a schematic diagram of the system composition principle of the third embodiment of the present invention, such as figure 2 As shown, terminals T1, T2, and T3 are terminals that support distributed video processing, T4 is a traditional conference TV terminal that does not support distributed video processing capabilities, and the MCU supports distributed video control and management functions.
[0078] Taking four pictures as an example, T1, T2, T3, and T4 are respectively located in a sub picture in the four pictures. Terminals T1, T2, and T3 support distributed video processing, so they can scale their video streams to an appropriate size and send them to the multicast address of the corresponding sub-picture, and receive other sub-pictures from the multicast address corresponding to the sub-picture. The video code stream of the screen, the four received video code streams are synthesized locally, and finally a multi-screen is generated. Terminal T4 ...
