Abstract
Distributed video coding is a research field which brings together error coding techniques along with video compression ones. Its core part is a Slepian-Wolf encoder which often involves turbo codes because of their strong error correction capabilities. The turbo encoder generates parity bits which are sent to refine the side information constructed at the decoder by interpolation using the neighboring key frames already received. For bit rate flexibility, these parity bits are punctured and sent gradually upon request until the receiver can correctly decode the frame. In this work, we introduce a novel distributed video coding scheme with adaptive puncturing that sends more parity bits when the virtual channel is noisy and less parity bit when it is not the case. Considerable compression performance improvement over the puncturing techniques used in literature is reported.
