DiMeNsion - 3 DVD Recorder Solution ™ Ser vo, 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 scene...
