Method, Device, and System for Multipoint Video Communication

A system for multipoint video communication, comprising:

• a multipoint control unit;
• multiple endpoint devices, wherein each endpoint device of the multiple endpoint devices corresponds to at least one image acquisition area, and
• wherein a first endpoint device of the multiple endpoint devices configured to:
• determine whether an image acquisition target exists in at least one image acquisition area corresponding to the first endpoint device within a current period;
• and
• skip reporting image information of the first image acquisition area within the current period to the multipoint control unit when the image acquisition target is absent from a first image acquisition area of the at least one image acquisition area within the current period.

A device for multipoint video communication comprising:

• a sender;
• and
• N sensors, wherein each sensor of the N sensors corresponds to one image acquisition area,
• wherein a first sensor of the N sensors is configured to determine whether an image acquisition target exists in a first image acquisition area corresponding to the first sensor within a current period, and
• wherein the sender is configured to skip reporting image information of the first image acquisition area within the current period to a multipoint control unit when the first sensor determines that the image acquisition target is absent from the first image acquisition area within the current period.
