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 StandardPlusTM 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

SiliconSoftwareTM 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
