CAMERA COUPLED REFERENCE FRAME

摘要

Techniques are provided for managing long-term reference frames (LTRFs) for two or more video sources. A first video source is selected from a plurality of video sources. The first video source is encoded to produce an encoded video stream, where a reference frame message identifies a recent video frame as long-term reference frame (LTRF) associated with the first video stream. The process is repeated for other video streams. The LTRF associated with the first video stream is used as a reference for temporal predictive coding upon receiving a signal that the first video source has been re-selected.
