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-
PlusTM design methodology, functions such as reverse trickplays
and zoom capability are provided. The ZR36710, through its Sil-
iconSoftwareTM feature, has the capability to integrate key
functions such as 3D audio and Karaoke.
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.
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.
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

output of DTS or MPEG 5.1 through the S/PDIF output. This
digital data is transmitted for use by an audio receiver for multi-
features can be implemented in the ZR36710, thus eliminating
the need for an external karaoke processor. Voice Canceling is
a feature to eliminate the singer's voice on a CD by comparing
left and right channels and filtering out the vocal content,
allowing you to sing along. The echo function provides the effect
of singing in a large auditorium and slightly modifies the singer's
voice to enhance the sound. Key Control adjusts the pitch of the
music by quarter tones to allow the pitch of the music to be
shifted to match the pitch of the singer's voice.
ZR36710 incorporates reverse trickplay functionality to provide
seamless reverse functions in addition to the standard trickplay
provides smooth transitions for a viewer to single step or fast
reverse through scenes.
for DVD decoding with a single 16 Mbit SDRAM. This dramati-
cally reduces the number of the chips and the size of the
required memory, thereby lowering the power consumption and
the overall cost of a DVD system.
High quality audio is a key feature of DVD and the Vaddis
supports the highest quality Dolby Digital possible for a DVD
player design. In addition, the functions of reverse trickplay and
zoom capability enhance the video playback. Support for DTS
passthrough enables the playback of video titles that are
encoded with DTS audio tracks. Support for MPEG5.1 provides
the same capability. In summary, the ZR36710 is ideally suited
for developing a high quality, feature rich third generation DVD
