Title:
配信されたソース符号化技術に基づいたサイドチャネルを利用して予測的なビデオコデックのロバスト性を高める方法、装置、及びシステム
Document Type and Number:
Japanese Patent JP5221620
Kind Code:
B2
Abstract:
A method, apparatus, and system for providing distributed source coding techniques that improve data coding performance, such as video data coding, when channel errors or losses occur. Errors in the reconstruction of the data is eliminated or reduced by sending extra information. Correlation between a predicted sequence and an original sequence can be used to design codebooks and find the cosets required to represent the original image. This information may be sent over another channel, or a secondary channel.
