Popis
Shrnutí:This paper investigates robust transmission of a coded video sequence over unreliable packet networks. A content-based error-resilient coding (CBERC) algorithm is proposed to prevent severe error propagation. Specifically, the CBERC encoder performs motion-compensated prediction by taking the video content into consideration. A criterion based on the worst-case scenario is also provided to determine appropriate CBERC threshold. The CBERC algorithm does not require a feedback channel and supports both point-to-point and multi-point communications. It is of low complexity and is compatible with all the widely accepted video coding standards such as H.263+, H.261, MPEG-1, MPEG-2 and MPEG-4.
