Device and method for managing bandwidth of video conference

A equipment for managing bandwidth of a video conference which is connected to at least one client device, comprising:

• at least one processor;
• a video forwarder unit;
• a multipoint control unit;
• a signal service unit;
• a storage unit;
• and
• one or more programs that are stored in the storage unit and executed by the at least one processor, the one or more programs comprising instructions for:
• acquiring a predetermined quantity of original video images from a video sent from the client device;
• compressing the video sent from the client device according to a default video compression parameter;
• acquire the compressed video images corresponding to the acquired original video images from the compressed video;
• detecting a current network bandwidth;
• comparing the current network bandwidth with a data bandwidth of the compressed video;
• calculating a video quality assessed value of the compressed video according to the acquired original video images and the compressed video images acquired in event the current network bandwidth is larger than the data bandwidth of the compressed video;
• determining whether the video quality assessed value of the compressed video is within a scope of predetermined quality requirement or not;
• and
• regulating the default video compression parameter to recompress the video until the video quality assessed value of the compressed video is within the scope of predetermined quality requirement while the video quality assessed value of the compressed video is beyond the scope of predetermined quality requirement.
