Patent attributes
Systems and techniques to reduce bandwidth usage of video frames in a videoconferencing system are described. A computing device may receive a first frame of a first video stream from an imaging device and decompose the frame into a plurality of portions. The computing device may select a first portion of the plurality of portions, determine that the first portion matches a sent portion in a sent catalog, determine a first identifier associated with the first portion, and send the first identifier to a server. The computing device may select a second portion of the plurality of portions, determine that the second portion fails to match any of the sent portions in the sent catalog, create and associate a second identifier with the second portion, store the second portion with the second identifier in the sent catalog, and send the second portion to the server.
