Abstract :
Our two-chip, real time, MPEG-2, simple-profile-at-main-level encoder supports NTSC 4:2:0 video signals with only three external memories. We have developed a compact encoder chip set. The key features of this chip set are a low encoding delay based on a simple profile at main level; wide-range motion estimation, which it performs using a hierarchical search; a flexible, macroblock level pipeline architecture based on RISC CPUs; and three small peripherals with no glue logic: a VRAM, synchronous DRAM, and FIFO DRAM
