DVxcel ™ Codecs for Video
Peripheral Applications
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.

Today an extensive amount of multimedia content is available on the
Web. As digital subscriber line (DSL) and cable modems become more popular, 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.

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

Engine
While enabling all of the applications
of the DVxcel-LE and DVxcel-VC, the
DVxcel-DT has the unique ability to
DVxcel™-DT Video Peripheral (transcoder) System Block Diagram
provide DV to MPEG transcoding.
This feature enables users to capture
audio/video content directly from their
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 distribution.
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 storage medium, the encode capabilities of the DVxcel product family can
offer compelling features for applications such as DVRs. More importantly, the DVxcel-VC and DVxcel-DT will provide users the ability to
view this stored content on their TV using the hardware decode functionality. 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.
