Abstract :
We describe a class of parameterized reversible variable length codes that have length distributions identical to Golomb-Rice codes and exp-Golomb codes. The pdfs to which these codes correspond are well matched to statistics of image and video data, thus enabling an increase in robustness to channel errors with no penalty in coding efficiency. These codes are applicable to MPEG-4 and other algorithms that aim to use variable length codes in error-prone environments
