HDD/DVD Recorder Processor

O V E R V I E W

The DiMeNsion-2 is the second generation family of DVD recorder processor

ing, yet cost-sensitive, A/V codec applications in consumer electronics products. A true

system-on-a-chip solution, the DiMeNsion-8652 (DMN-8652) empowers dual-drive prod-

ucts while reducing cost, design complexity, power consumption and time-to-market.

The DMN-8652 enables consumer electronics manufacturers to offer a category

of products that leverages the flexibility provided by the combination of hard disk and

optical disk drives. The DMN-8652 accepts video from broadcast TV and other analog

video sources and compresses and formats the video for storage on hard disk, or on DVD

discs in industry-standard recordable formats (DVD-RAM, DVD-RW/R, DVD+RW/R). It

transcodes DV-25 video for storage on hard disk or DVD. The DMN-8652 supports simul-

taneous play back of video from hard disk or DVD, and a range of background copying

operations (including dubbing and transrating) between the hard disk and optical drives.

of video blurring in moving scenes.
