摘要：

This paper presents an encoding algorithm which allows a Main Profile Main Level MPEG-2 decoder to reduce the external dedicated memory. Typically, for most TV applications, a 16 Mbit SDRAM is needed, but using a new compression approach it is possible to reduce this amount of memory to less than 8 Mbits for PAL sequences. The REMPEG50 (REduced Memory MPEG decoder and 50 %frame compression) is a modified architecture of a MPEG-2 decoder that needs only one half of the external memory while keeping a full comparibility with the standard MPEG-2 decoder. When compared to a "pure" MPEC-2 decompression scheme [1], this shows a very good trade-off between loss of MPEG-2 quality over different bit rates and overall increased complexity.
