Preliminary
MPEG4 Encoding LSI
OVERVIEW
The ML86410 is an LSI that encodes YUV (YCbCr) format digital video signals into MPEG-4-ASP format ones in
real time.
The LSI achieves high picture quality by a unique high-speed high-quality motion search method and a unique
coding rate control method. For video input, the LSI supports progressive video output from camera modules and
interlaced video output from NTSC/PAL digital video decoders.
