Abstract

The output from an H.261 or MPEG video coder consists of macroblocks of differing lengths. Two methods of packing the macroblocks into ATM cells are considered, depending on whether or not part of an uncompleted macroblock may be carried over to the next cell. It is shown that while due to cell loss for a single source loosely packed cells result in a smaller number of lost macroblocks, in a multiplexed network closely packed cells have a marginally better performance.
