CXD1922Q
MPEG-2 Video Encoder
Description
The CXD1922Q is a highly-integrated device includ-
ing MPEG-2 encoder, motion estimation, and system
and rate controller on a single chip. The device is ideal
for low-cost solutions in consumer products, storage
media, communications and authoring applications.
The CXD1922Q supports MPEG-2 MP@ML encoding
compliant with ISO/IEC 13818-2 for frame structure
encoding.
