Methods and systems for minimizing decoding delay in distributed video coding

摘要

This disclosure generally relates to encoding, transmission, and decoding of digital video, and more particularly to methods and systems for minimizing decoding delay in distributed video coding (DVC). In one embodiment, a video decoding method is disclosed, comprising: obtaining side information; obtaining a syndrome bit chunk corresponding to a non-key-frame bit-plane; performing, via one or more processors, at least one non-key-frame bit-plane channel decoding iteration using the side information and the syndrome bit chunk; generating a decoded bit-plane via performing the at least one non-key-frame bit-plane channel decoding iteration; determining a bit error rate measure for the decoded bit-plane; determining, based on the bit error rate measure, a number of additional syndrome bit chunks to request; and providing a request for the additional syndrome bit chunks.

1. A non-transitory computer-readable medium storing processor-executable video encoding instructions for:
obtaining a non-key frame; receiving a dynamic multiple syndrome bit chunks request; generating syndrome bit chunks by distributed video encoding of the non-key frame; and providing the syndrome bit chunks after receiving the dynamic multiple syndrome bit chunks request.
