DiMeNsion^™- 3 DVD Recorder Solution
Servo, Video Decoder and System Processor
OVERVIEW
The LSI Logic DiMeNsion^™-3 comprehensive DVD recorder solution includes
a single-chip DVD recorder DSP servo + analog front end (AFE); a family of
analog video decoders; and a third-generation DoMiNo^™-based DVD recorder
processor. The DiMeNsion-3 solution is intended for higher performance, yet
cost-sensitive, worldwide DVD recorder and combination products.
The high level of integration of the DiMeNsion-3 solution drastically reduces
system component count, and consequently system cost. Figure 1 shows a block
diagram of an advanced DVD recorder based on the DiMeNsion-3 solution. With
its unique Unified Memory Architecture (UMA), the entire system requires only a
single DRAM and Flash device. Integrated Real Time Clock and low power standby
mode eliminate the need for a front panel microcontroller.
In addition to enabling cost-effective designs, the DiMeNsion-3 solution
enables higher-end features, including SACD and DVD Audio for universal
audio players; MPEG-4 and DivX^® encoding and playback, enabling up to
12 hours of recording on a single DVD disc; SD to HD up-conversion and
HD JPEG; LSI Logic’s Direct Digital Dub^™ technology to simplify the transfer
of personal digital content from a camcorder to DVD over FireWire; and
new, more advanced edge filtering and deinterlacing capabilities to provide
impressive noise reduction on analog inputs and eliminate video blurring in
moving scenes via DoMiNoFX^™ technologies. The DoMiNoFX industry-leading
pre- and post-processing video technologies create a visibly superior viewing
experience. This coupled with LSI Logic’s fifth-generation compression technology,
offers excellent video quality, even at very low bit rates.
