Multiview Video Coding


Multiview Video Coding

Multiview Video Coding (MVC) is an amendment to H.264/MPEG-4 AVC video compression standard developed with joint efforts by MPEG/VCEG that enables efficient encoding of sequences captured simultaneously from multiple cameras using a single video stream.

MVC is intended for encoding stereoscopic (two-view) video, as well as free viewpoint television and multi-view 3D television. The Stereo High profile has been standardized in June 2009; the profile is based on MVC toolset and is used in stereoscopic Blu-ray 3D releases.

MVC stream is backward compatible with H.264/AVC, which allows older devices and software to decode stereoscopic video streams, ignoring additional information for the second view.

Technical Overview

Multiview video contains a large amount of inter-view statistical dependencies, since all cameras capture the same scene from different viewpoints. Therefore, combined temporal and inter-view prediction is the key for efficient MVC encoding. A frame from a certain camera can be predicted not only from temporally related frames from the same camera, but also from the frames of neighboring cameras. These interdependencies can be used for efficient prediction.[1]
