Interpolation architecture of motion compensation unit in decoders based on H.264 video coding standard

摘要

PURPOSE: An operator structure of a movement compensator for a decoder is provided to reduce reference memory access time in a movement compensating structure of H.264 decoder and improve the performance of the decoder. CONSTITUTION: An operator structure of a movement compensator for a decoder includes a VLD(Variable Length Decoder), a prediction unit, and a DF(Deblocking Filter). The VLD includes parser, Exp-Golomb, and CAVLD. The parser classifies the input data division. Exp-Golomb makes the parameter extraction. CAVLD makes the extracting coefficient. The prediction unit includes ITQ(Integer Transform and Quantization), an MC(Motion Compensation)(121), and an IP(Intra Prediction). The ITQ changes coefficient with a quantization. The IP predicts the prediction within a slice.
