Abstract

Spatial domain redundancy is studied for packet erasure recovery in a video coding system. The image is partitioned into a checkerboard pattern of white (W) and black (B) blocks. A subset of pixels in the B (W) blocks is selected to be encoded as redundant information with the W(B) blocks. The Yu, Liu, and Marcellin (1996) approach is generalized and several different redundancy patterns are investigated. Significant improvement in interpolation performance is achieved with different redundancy patterns
