architecture. The DiMeNsion-2 is intended for demand-
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
permits control of DV camcorders connected via FireWire
廬
using the AV/C protocol, and
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.
