DESCRIPTION
The ZR36730 Vaddis IV DVD decoder is targeted at fourth
generation DVD and convergence products. With its high level of
integration and flexibility, the ZR36730 is a versatile digital video
and audio processor. This new generation part builds upon
Zoran's success in the DVD market, incorporating enhanced
audio and video functionality. Leading audio algorithms, such as
HDCD, MP3, DTS, Dolby Digital, Pro Logic, and MPEG 5.1
decoding are supported in this single chip solution. In addition,
the video feature set has been expanded to include image
quality enhancements and augmented On-Screen-Display
(OSD) functionality. Through the StandardPlus
TM
design
methodology, Zoran is building upon the standard to provide
leading-edge capabilities for advanced DVD players and
convergence devices, such as WebDVD players.

DVD Decoding
The ZR36730 handles all aspects of DVD decoding according to
the specification. This single chip solution performs DVD
authentication/decryption, demux and parsing, MPEG-2 or
MPEG-1 video decode, sub-picture decode, highlight
processing, and audio/video synchronization. The integrated
OSD unit provides 32 colors and 8 blending levels which are
necessary for sophisticated on-screen user interfaces. In
addition, DVD-Audio is supported by the ZR36730's integrated
digital audio processor.

Highest Quality Audio
With its integrated 54 MIPS Audio Decode Processor (ADP
unit), the ZR36730 is capable of supporting a host of advanced
audio algorithms. Based on Zoran's field proven audio DSP
technology, the ADP unit enables the development of a DVD
system which meets the highest quality audio output standards,
such as for Dolby certification. In addition, algorithms from our
SiliconSoftware
TM
library are supported, including 3D
Headphones and enhanced Karaoke. The embedded ADP unit
is a 20-bit audio DSP enabling Vaddis solutions to deliver
audiophile quality output.

KEY FEATURES
Image Enhancement Filters
The ZR36730 incorporates several filtering functions for
enhancing the image quality during normal and trick play
operations. Progressive interpolation, sharpness and brightness
equalization are implemented with these output filters. When
using pause, fast forward, or fast reverse, the progressive
interpolation filter provides a high quality image output, without
displaying annoying artifacts. The ZR36730 supports video edge
enhancement and brightness control via programmable filter
coefficients, giving it the flexibility to control the sharpness,
intensity, and dynamic range of the image.
On-chip Video Encoder and Video DACs
The ZR36730 includes an advanced video encoder core capable
of outputting YCrCb, RGB, CV, or S-video via high quality 10-bit
video DACs. The video encoder supports programmable chroma
and notch filters to optimize the picture quality, even when
displaying on lower quality TV's.
Multiple Standards
The ZR36730 supports all of the key digital video and audio
standards. Support for DVD, CVD, SuperVCD, VideoCD, DVCD

and Audio CD is provided. SuperVCD is a new digital video
standard for the Asia market and is rapidly replacing the
VideoCD market. Enhancements to the Audio CD is provided
through HDCD, 3D audio and Music Modes that expand the
sound experience for the listener.
DTS Passthrough and MPEG 5.1 Decoding
The ZR36730 provides DTS passthrough and MPEG5.1 audio
stream decoding capability. An audio receiver can decode the
DTS data which is sent digitally through the S/PDIF port. MPEG
5.1 output can be either through the S/PDIF or analog audio
ports.
DVD-Audio Support
The following DVD-Audio formats are supported by the 54 MIPS
ADP in the ZR36730:
Linear PCM 5.1 Multichannel (24-bit, 96 kHz sampling)
Linear PCM 2-channel (24-bit, 192 kHz sampling)
MLP 2-channel (24-bit, 192 kHz sampling)
Compressed Audio
The recent explosion of applications for compressed audio has
caused the popularization of standards such as MP3. With the
ability to play MP3 disks with a DVD hardware platform, new
convergence applications are enabled.
HDCD
HDCD is a technology that provides 20-bit resolution from
standard Audio CDs. Widely available on many CDs today,
HDCD expands the existing 16-bit data on an Audio CD to 20-
bits, providing a higher quality audio output compared with
typical Audio CDs.
Audio Enhancement Algorithms
Beyond the decoding of DVD or compressed audio, post-
decoding algorithms such as Virtual Surround Sound, 3D
Headphones, and Music Modes enhance the listening
experience. Virtual Surround Sound gives the listener a
multichannel effect through only two speakers. Likewise, 3D
Headphones gives the sensation that the listener is surrounded
by a theatre speaker system, when the audio is actually
delivered via the two speakers on the headphones. Music
modes expand the sound of the room by simulating a theatre or
concert hall listening environment.
The Solution for the Consumer Market
The ZR36730 is the leading solution for the consumer DVD
market today. With its high level of integration and rich feature
set, the Vaddis IV is a cost effective IC which delivers the
versatility and performance demanded. As Zoran's fourth
generation integrated DVD decoder, it has a mature, field-
proven architecture. Enabling emerging applications such as
WebDVD, Set Top Box (STB), and Digital VCRs, the ZR36730 is
the versatile digital video and audio decoder for consumer
electronics products.
