ABSTRACT:
Presented herein are optimized single inverse quantization engines for a plurality of standards. In one embodiment, there is presented a system for inverse quantizing quantized frequency coefficients. The system comprises an inverse quantizer for inverse quantizing video data encoded in accordance with a first encoding standard and for inverse quantizing video data encoded in accordance with a second encoding standard. In another embodiment, there is presented a decoder for decoding video data. The decoder comprises an inverse quantizer operable to inverse quantize video data encoded in accordance with a first encoding standard and for inverse quantizing video data encoded in accordance with a second encoding standard.
