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.
Claims16
A method comprising:
- receiving two or more input bitstreams including receiving at least one advanced video coding (AVC) bitstream;
- decoding the two or more received input bitstreams;
- and
- transcoding the two or more decoded input streams into one or more output bitstreams including transcoding each decoded bitstream using multiview video coding (MVC) to generate one or more MVC output bitstreams.
A device comprising:
- a first decoder to receive a first AVC bitstream and to generate meta-data associated with the first AVC bitstream;
- and
- a transcoder to receive the meta-data and to generate a MVC output bitstream based on the meta-data.
