FIXED-LENGTH ENTROPY CODING FOR ROBUST VIDEO COMPRESSION

Entropy coding is a fundamental stage in all video compression algorit hms in terms of compression efficiency and error resilience Variable-l ength entropy codes (VLC) are used in current video codecs, Designed t o be employed in noiseless applications, these codes are very sensitiv e to transmission errors. This paper proposes the use of fixed-length entropy codes (FLC) as an alternative to VLC in video compression appl ications, In noisy transmissions, the FLC-based codec has shown a supe rior performance compared to VLC-based codecs with synchronization wor ds, while matching its performance in terms of coding efficiency.
