OVERVIEW

The DVxcel™-LE, DVxcel™-VC and DVxcel™-DT are the latest offerings in

the DVx family of products. DVxcel-LE is designed to enable very low-cost

video peripherals, based on MPEG-1 and MPEG-2 compression standards for

archiving and web-streaming applications. The DVxcel-VC, a single-chip

MPEG-2 codec capable of encoding and decoding video simultaneously,

is targeted at the emerging time-shift and digital video recording (DVR)

applications. The DVxcel-DT includes the same functionality and features as

the DVxcel-VC, with additional support for DV encode and decode as well

as transcoding from DV to MPEG-2; features that are critical for enabling

new video editing applications. All support both NTSC and PAL formats.

Based on LSI Logic’s fourth-generation video processor architecture,

these devices are optimized, both in hardware design and functionality, for

high-quality, low-cost video-centric consumer applications. Using LSI Logic’s

proven PerfectView®encoding algorithm, this product family delivers the

highest quality video encoding with the lowest bit rate of any consumer-based

solution.

TARGET APPLICATIONS

Web Sharing

Today an extensive amount of multimedia content is available on the

Web. As digital subscriber line (DSL) and cable modems become more popu-

lar, the need for high-quality, low bit rate video is increasing. The DVxcel’s

sophisticated MPEG-1 and -2 compression algorithms provide superior quality

and can accommodate bit rates as low as 384 Kbps. Video compression is

critical for Web sharing and distribution where file size is important.

DVXCEL-LE FEATURES:

• 208 PQFP

• MPEG-1 encode: 384 Kbps to 4 Mbps

• Resolution: SIF

• MPEG-2 encode: 1.8 Mbps to

10 Mbps

• Resolution: 720, 704, 544, 480, 352

• VBR and CBR support

DVxcel-LE is in a PQFP package to

support low-cost PCB manufacturing.

With its high-quality compression and

low bit rate, it allows even POTs con-

nected PCs to stream audio and video

content. The DVxcel-LE enables video

streaming and video mail applications

for both narrowband (POTs) as well as

broadband (cable, DSL) connections.

DVXCEL-VC FEATURES:

• 308 BGA

• MPEG-1 encode: 384 Kbps to 4 Mpbs

• Resolution: SIF

• MPEG-2 codec (up to full resolution)

• TV Out

• MPEG-2 encode: 1.8 Mbps to

10 Mbps

• Resolution: 720, 704, 544, 480, 352

• VBR and CBR support

The DVxcel-VC is a single-chip codec

solution for time-shift applications.

It provides the ability to pause, fast-

forward, rewind and instant-replay live

broadcast television. In addition, its

decode functionality enables users to

store content on VHS tape.

Video Archiving

Video archiving is a process of converting analog tapes (8mm

and VHS) to other digital storage devices such as DV tape and DVDs.

Users can capture both video and audio from a camcorder or a VCR,

using either MPEG-1 or MPEG-2 hardware-based compression, and

send it to a PC via the USB connection. There, the content can be

authored and formatted for CD-R, CD-RW, VCD and DVDs. DV content

can also be recompressed to be stored on DVDs. This process is called

DV to MPEG transcoding. With DVxcel’s ability to perform DV to MPEG

DVXCEL-DT FEATURES:

• 308 BGA

• MPEG-1 encode: 384 Kbps to 4 Mpbs

• Resolution: SIF

• MPEG-2 codec (up to full resolution)

• TV Out

• MPEG-2 encode: 1.8 Mbps to

10 Mbps

• Resolution: 720, 704, 544, 480,

352

• VBR and CBR support

• DV25 encode

• DV25 decode

• DV to MPEG transcoding

While enabling all of the applications

of the DVxcel-LE and DVxcel-VC, the

DVxcel-DT has the unique ability to

provide DV to MPEG transcoding.

This feature enables users to capture

audio/video content directly from their

DV camcorder to store, edit or view on

their PC or TV.

transcoding in real time, the storage requirement on your PC

decreases six fold. It also eliminates the need to convert the digital

content back to analog during authoring. DVxcel also addresses the

large installed base of analog VCRs with its unique ability to take

edited content from the PC and convert it back to VHS tape for distribu-

tion.

Time-Shifting

DVxcel-DT and DVxcel-VC supply full encode and decode

(codec) functionality. For those users who would like to view TV

programming on a PC, by utilizing the hard disk drive (HDD) as a stor-

age medium, the encode capabilities of the DVxcel product family can

offer compelling features for applications such as DVRs. More impor-

tantly, the DVxcel-VC and DVxcel-DT will provide users the ability to

view this stored content on their TV using the hardware decode func-

tionality. Not only can users play back the content on the TV but they

also have the ability to stop, start, pause, rewind and even skip

commercials. This is called time-shifting. While the recording may be

linear, the play back can be selected from anywhere from start of the

program to a point of live broadcast.
