LSI Logic DVxcel™ Digital Video Recorder (DVR) System Block Diagram

OVERVIEW

The LSI Logic DVxcel™MPEG-2 video codec is a high-quality,

single-chip digital video processing solution that is ideal for

consumer digital recordable products, including DVD recorders.

In addition to encoding and decoding, LSI Logic DVxcel has the

capability to simultaneously encode and decode MPEG-2 video,

enabling low-cost digital video recorder (DVR) applications. LSI

Logic DVxcel, the latest in the DVx family of codecs, is based on

LSI Logic’s fourth-generation video processor architecture. LSI

Logic DVxcel has been optimized, both in hardware design and

functionality for high-quality, low-cost digital consumer recordable

applications. Using LSI Logic’s proven PerfectView®encoding

algorithm, LSI Logic DVxcel delivers the highest-quality video

encoding of any consumer-based solution.

LSI Logic DVxcel™MPEG-2 Video Codec

DEVICE FEATURES:

Optimized for embedded designs,

LSI Logic DVxcel features the

following hardware interfaces:

• Flexible 16/32-bit host interface

• Host DMA target or primary 8-bit

hardware I/O port for bitstream

data transfers

• Secondary 8-bit hardware port

for bitstream transfers

• Tertiary 8-bit hardware port for

bitstream transfers

• 8- or 10-bit ITU-656 video input

port

• 8-bit ITU-656 video output port

• Serial audio interfaces for audio

capture and playback

LSI Logic DVxcel is based around a

110 MHz Micro-SPARC®RISC core

and includes special hardware to

implement:

• Video compression

pre-processing

• Motion estimation and

compensation

• DCTs and IDCTs

• Variable-length encoding and

decoding

• High-quality video scaling and

compositing

TARGET APPLICATIONS

LSI Logic DVxcel offers significant design advan-

tages for the following applications:

Digital Video Recorder (DVR)

LSI Logic DVxcel can be the core of a low-cost DVR

application that has the ability to pause, fast-forward,

rewind, and instant-replay live broadcast television. LSI

Logic DVxcel simultaneously encodes and decodes video

while also ensuring audio/video synchronization. Coupled

with an embedded processor, LSI Logic DVxcel can enable

a two-chip solution to provide a complete digital video

time-shifting application.

DVD/Optical Disc Recorder

Coupled with a DVD decoder (such as the LSI Logic

ZiVA-4), LSI Logic DVxcel can provide the MPEG-2 video

and system encoder portions of a DVD/optical disc

recorder. LSI Logic DVxcel’s on-chip MPEG-2 program

stream multiplexing and DVD-VR RTRW format generation

provides a clean and efficient system design for DVD/optical

recorders, while the DVD decoder ensures compatibility

with playback of existing content.

Personal TV Functions

LSI Logic DVxcel’s programmable architecture can

enable advanced personal TV features. While encoding

video, vertical blanking interval (VBI) data can be

captured and decoded by the codec to provide additional

digital content information such as closed caption data

and electronic programming guide data.
