MPEG-4 Decoder for Set-top, DVD and Streaming Applications
Description
The EM847x family is a single-chip MPEG audio/video decoder that supports
DVD-Video, Superbit™ DVD, SVCD, VCD and audio CD media formats.
Video decoding support includes MPEG-1, MPEG-2 MP@ML and MPEG-4
advanced simple video profile Level 5
Dolby
and 16-bit linear PCM. DVD-Video support includes hardware CSS decryp-
tion, 16:9 and 4:3 aspect ratios, letterboxing, 3:2 pull-down, multiple angles
and sub-picture.
Based on the company’s award-winning REALmagic
nology, the EM847x family provides highly-integrated solutions for high-qual-
ity decoding of MPEG-1, MPEG-2 and MPEG-4. Positioned as a cost-
effective solution for streaming video clients, advanced digital set-top boxes
