A recursive shape error concealment algorithm
The encoding of shape information is a distinguishing feature of MPEG-4. In error prone communication networks, it is important and efficient to conceal shape errors spatially, so...

High performance error concealment algorithm by motion vector refinement for MPEG-4 video
—In this paper, a new error concealment algorithm by recursive motion vector refinement is proposed. The proposed method utilizes the top/bottom motion vectors of lost MB in curr...

Rate-Distortion Optimized Slicing, Packetization and Coding for Error Resilient Video Transmission
This paper presents an algorithm to optimize the tradeoff between rate and expected end-to-end distortion of a video sequence transmitted over a packet network. The approach optim...

Prescient mode selection for robust video coding
In standard predictive video coders, intra-mode coding of macroblocks (MBs) provides packet loss resilience, at the cost of reduced compression efficiency. Conventional mode selec...
