Abstract
A video system includes an encoder for generating a compressed bit stream in response to a received video signal. A transitional location is located in the bit stream that includes skip macro-block encoding, where the transitional location provides an indication where a linear relationship starts to exist between a length of the encoded bit stream and a length of a number of skipped macro-blocks. The skipped macro-blocks in the bit stream before the transitional location are encoded using a predetermined nonlinear relationship between the length of the encoded bit stream and the length of the number of skipped macro-blocks, whereas skipped macro-blocks in the bit stream are encoded using a linear relationship between the length of the encoded bit stream and the length of the number of skipped macro-blocks.
