Abstract
Systems, methods and computer program products for transcoding advanced video coding (AVC) bitstreams into multiview video coding (MVC) bitstreams are described. In some implementations, a MVC transcoder may be used to convert non-anchor pictures (e.g., at a specified temporal point) into anchor pictures by using only inter-view prediction. The MVC transcoder also may utilize inter-view reference pictures (in addition to temporal reference pictures) in the motion estimation/mode decision functions of the non-anchor pictures. The output of the MVC transcoder may be one or more MVC bitstreams each representing a different view of a same scene or image.
