Abstract :
Entropy coding is a fundamental stage in all video compression algorithms. Variable length entropy codes (VLC) are used in current video codecs. Designed to be employed in noiseless applications, these codes are very sensitive to transmission errors. This paper proposes the use of fixed length entropy codes (FLC) as an alternative to VLC in video compression applications. In noisy transmissions the FLC codes have shown a superior performance compared to VLC schemes with synchronization words
