Decoder system for decoding multi-standard encoded video

摘要

Presented herein are a decoder system for decoding multi-standard encoded video. In one embodiment, there is presented a system for decoding video data. The system comprises an outer loop symbol interpreter and an inner loop symbol interpreter. The outer loop symbol interpreter decodes VC-1 syntax and AVC syntax, at a slice or picture level. The inner loop symbol interpreter decodes VC-1 and AVC syntax at a macroblock level.

1. A system for decoding video data, said system comprising:
a first symbol interpreter for decoding VC-1 syntax and AVC syntax, at a slice or picture level, the first symbol interpreter determining descriptor data including at least one of a picture type, a picture length, a picture width, a pointer to bit plane data, a pointer to a slice structure, or a length of slice data; and a second symbol interpreter for decoding VC-1 and AVC syntax at a macroblock level in response to the descriptor data, the second symbol interpreter including a coefficient constructor for constructing coefficients from the VC-1 syntax at the macroblock level or a vector constructor for constructing vectors from the VC-1 syntax at the macroblock level.
