Video source coding with decoder side information

摘要

A method and system (3000) of decoding video data using joint decoding (3100) of independently encoded sources (1010 and 3012) is disclosed. The method includes storing (1030) an initial estimate of first media data from a first source (1010). Second media data (3032) from a second source (3022) is received, with the second media data comprising parity bit data for correcting estimates derived from the first media data. The stored initial estimate is then retrieved, and the retrieved initial estimate and the received second media data are utilized to decode (3100) the media data.

1. A method of decoding media data of a scene using joint decoding of independently encoded sources, said method comprising the steps of:
decoding each key frame of a plurality of key frames of first media data of the scene received from a first source of said independently encoded sources; storing the plurality of decoded key frames at a storage location separate from the independently encoded sources; receiving second media data of the scene from a second source of said independently encoded sources, said second media data comprising parity bit data; retrieving a set of key frames from the plurality of decoded key frames stored at the storage location; modifying the set of key frames retrieved from the storage location in favor of a current brightness condition of the scene; and utilizing the set of modified key frames to decode the second media data of the scene.
