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.  
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.  
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  
KEY FEATURES  
Image Enhancement Filters  
On-chip Video Encoder and Video DACs  
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.  
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
