Memory reduction for HDTV decoders

摘要

In this paper, we propose a low-cost memory reduction scheme which can reduce the memory requirement for full HDTV decoding from 12 MB to 4 MB. This scheme uses a switc table architecture that allows HDTV decoding with scalable memory reduction rations. Depending on the input format and the amount of available memory, the scheme performs 1/4 or 1/2 memory reduction or no memory reduction.
