DESCRIPTION
The ZR36710 DVD decoder is targeted for third generation DVD
products. The highly integrated ZR36710 is ideal for developing
a high-quality DVD player. The product is based on Zoran’s
strong history in the DVD marketplace. Through the Standard-
Plus™ design methodology, functions such as reverse trickplays
and zoom capability are provided. The ZR36710, through its Sil-
iconSoftware™ feature, has the capability to integrate key
functions such as 3D audio and Karaoke.
DVD Support
The ZR36710 handles all aspects of DVD decoding according to
the DVD Specification. The single-chip device performs DVD
authentication/decryption, demux and parsing, MPEG-2 or
MPEG-1 video decode, sub-picture decode, highlight process-
ing, audio/video synchronization, Dolby Digital decoding, Pro-
Logic decoding and 3D audio. In addition, an on-screen display
unit offers overlayed graphics and a closed caption modulator
provides support for line 21 data.
Highest Quality Audio
At the heart of the Vaddis ZR36710 are two powerful processing
units: the Demux/Video Processor (DVP unit) and the Audio
Decode Processor (ADP unit), a user programmable, 40 MIPS,
DSP engine. The DVP unit operates from downloadable micro-
code to parse the bitstream and route data to the appropriate
units. The Picture Reconstruction Unit completes the MPEG-2 or
MPEG-1 video decode and passes the image to the Video Post
Processing (VPU unit). The VPU unit performs vertical/horizon-
tal scaling, decodes and blends Sub-picture data, inserts Line 21
(close caption) text and overlays On Screen Display data.
The internal architecture of the ZR36710, which is based on
Zoran’s field proven audio DSP, enables the development of a
DVD system which meets the highest quality audio standards.
The ZR36710 DVD decoder includes an embedded 20-bit high-
performance audio DSP which enables the Vaddis architecture
to perform at audiophile quality for its audio output signals. Other
solutions, which use 16-bit audio technology cannot attain this
status. The high performance capability of the embedded audio
DSP enables the implementation of additional audio processing
algorithms such as Karaoke and 3D audio.
