Abstract

An H.264/AVC encoder LSI (named “SARA”) that supports High422 profile, as well as 422 profile of MPEG-2, has been developed for HDTV broadcasting infrastructures. It contains three motion estimation and compensation (ME/MC) engines with wide search ranges of -217.75 to +199.75 horizontally, -109.75 to +145.75 vertically, which can utilize almost all H.264/AVC ME/MC coding tools, such as multiple reference frame, variable block size, quarter-pel prediction, macroblock adaptive field/frame prediction (MBAFF), spatial/temporal direct mode, and weighted prediction. Our evaluations show that it can encode fast moving scenes with 1.2dB to 1.7dB higher than the JM. It was successfully fabricated in a 90-nm technology, and integrates 140 million transistors.
