Abstract
Described herein is a context adaptive variable length code decoder for decoding macroblock adaptive field/frame coded video data. In one embodiment, there is presented a context adaptive variable length code decoder. The context adaptive variable length code decoder comprises a symbol decoder, and a left neighbor buffer. The symbol decoder decodes context adaptive variable length code symbols representing frequency coefficients associated with a partition of a macroblock. The left neighbor buffer stores information about another partition, the another partition being a left neighbor of the partition. The information about the another partition is overwritten by information about the partition.
