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 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.
