MPEG-2 Encoder

Overview

The MB86391 is a full MP@ML compliant MPEG-2 encoder that integrates video, audio and system encoders all on a single chip.

The MPEG-2 encoder takes advantage of high-performance MPEG-2 compression algorithm developed by Fujitsu. This device is a combination of Hardware and Software processed by an internal SPARClite CPU. It is expected to be a key component for realising higher performance and more compact digital audio-recorder, camcorder, video communication, etc.
