"Multiple Description Coding for Error-Resilient Video
Transmission"

By Miss Mengyao Ma


Abstract:

Since the quality of compressed video is vulnerable to errors, video
transmission over un-reliable Internet is very challenging today.
Multiple Description Coding (MDC) is an error resilience technique to
encode the source into multiple streams, which are sent to the destina-
tion through diRerent channels. The strategy of MDC is that an arbitrary
set of descriptions can be received to construct the video with acceptable
quality. In this paper, we review some MDC approaches, categorized by the
dimension of description sub-sampling;  namely, spatial or temporal. In
spatial MDC, the blocks of each frame, or the motion vector and the
residues of each block are coded into multiple descriptions; while in
temporal MDC, the video sequence is coded into multiple decodable streams,
each with its own prediction process.
