Video control method, video conference terminal and multi-point control unit (mcu)

A video control method applied to a multi-point control unit (MCU), comprising:

• receiving video code streams respectively sent by a plurality of video conference terminals;
• receiving identifiers P and motion quantities R respectively corresponding to the video code streams sent by the plurality of video conference terminals, the identifier P indicating whether there is a person in the corresponding video code stream or not;
• and
• sorting the video code streams according to the identifiers P and the motion quantities R respectively corresponding to the video code streams, and selecting video code streams corresponding to the video conference terminals ranked top M for synthesis and output, and/or selecting a video conference terminal corresponding to a video code stream ranked first as a broadcast source.

A video control method applied to a multi-point control unit (MCU), comprising:

• receiving video code streams respectively uploaded by a plurality of video conference terminals;
• performing human facial recognition on each of the uploaded video code streams and determining a motion quantity R for each of the video code streams, wherein each of the video code streams uses its own identifier P to indicate whether there is a person in the video code stream or not;
• and
• sorting the video code streams according to the identifiers P and the motion quantities R respectively corresponding to the video code streams, and selecting video code streams ranked top M for synthesis and output, and/or selecting a video conference terminal corresponding to a video code stream ranked first as a broadcast source.
