General Description
The ZR36215 decoder is targeted for the new generation of Digital
Video products in Asia. The highly integrated ZR36215 is ideal for
developing a SuperVCD player design. The product is based on
Zorans strong history in the Digital Video marketplace. The
ZR36215 provides key features such as MPEG-1 & 2 Video
decoding, MPEG audio decoding, integrated OSD and OGT,
VideoCD 2.0 compatibility and embedded Karaoke functions.
The ZR36215 handles all aspects of SuperVCD decoding. The
single chip device performs demux and parsing of the bit stream
MPEG-2 or MPEG-1 video decoding, MPEG audio decoding and
audio/video synchronization. It includes an OGT Processor for
overlayed graphics and text, and an OSD mechanismto support
overlay of user generated text and graphics. The ZR36215 performs
vertical/horizontal filtering & scaling of the output video to ensure
high quality displayed video.
The ZR36215 has an integrated 40MIPS DSP to provide the
flexibility for enhanced features of the SuperVCD standard
specification. This embedded DSP supports programmable
algorithms such as stereo enhancement , 3D audio generated froma
multi-channel audio stream and full Karaoke. The 160 pin package
is compact and saves additional board space. In addition, a single
16-Mbit SDRAMcan be used for all the operations of the ZR36215,
thus saving additional cost and board space.
