Vaddis IV™ INTEGRATED DVD DECODER

Zoran Corporation 

Vaddis IV™ INTEGRATED DVD DECODER

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.

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.

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.

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

the versatile digital video and audio decoder for consumer

electronics products.
