The characteristics and application analysis of single-chip dual-encoding HDDDVD recording system processor DMN8653

The third-generation single-chip dual-encoding HDD/DVD recording system processor DMN8653 launched by LSILogic Corporation integrates dual-encoding for the dual-tuner HDD/DVD recording platform. Dual encoding enables DVD recorder manufacturers to provide market-leading features such as the ability to digitally record two TV programs at the same time when watching a live playback of one of the selected channels. These are the increasingly popular features of today's high-end digital set-top boxes. Features like this will drive the market share of DVD recorders, DVD/PVR and new generation TV monitors.

According to IDC's analysis, the DVD recorder processor market will reach $875 million by 2008. The DVD burner processor integrated with dual encoding and other features can reduce the BOM cost of the entire system, and can combine high-end and low-end DVD burners.

Due to the high degree of integration, DMN-8653 does not require a second MPEGA/V encoder, and has a flexible unified standard memory architecture (UMA), which reduces the system BOM cost. The flexible UMA enables the use of two x32DRAMs to configure a high-performance HDD/DVD burner, or a single x16DRAM to configure an entry-level HDD/DVD burner. Using and integrated AFE LSILogicL3200 optical read/write servo/DSP pairing, can further optimize the system level. DMN8653 supports MPEG-1, MPEG-2 and MPEG-4 format video encoding and DivX? The certified code allows the recording time of a single DVD disc to be up to 12 hours or the HDD has a recording time of hundreds of hours. DMN8653 also supports the best DVD playback function, including DivX? Certified playback, SACD, DVD-Audio, SD to HD video playback with improved performance is output to HDMI, and HD-JPEG output for still images.

DMN8653 has better performance than DMN8652, making high-speed dubbing and dual data stream encoding possible. With unique single-chip dual-stream encoding characteristics, the DMN8653 processor can have real time-shifting functions (program pause, rewind and/or fast forward to real-time TV when recording another channel. With such a single-chip processor, DMN8653 can Minimize system cost by $10.0.

The DMN8653 system processor also includes LSILogic’s industry-leading DVD burner features, including video pre- and post-processing technology, which enables DVD recording, playback and archive files to have the highest quality video, and its direct digital dubbing (DirectDigitalDub) technology simplifies The transfer of personal digital content from the camera to the DVD over FireWire, the YesDVD smart software solution makes automatic editing and home video conversion easy, and also includes a fully integrated USB host interface for USB digital cameras and USB flash card adapters. DMN8653 keeps In addition, the software is compatible with previous LSILogic's DMN processors, allowing manufacturers to bring products to the market faster.

The main features of DMN8653 are included as follows:

Double encoding for single and double tuner combination products,

Flexible memory configuration for high-performance or entry-level combination products,

MPEG-4 recording and playback,

Simultaneous interlaced/progressive scan analog video output,

SACD replay,

Support HDMI for digital HDTV output,

Integrated IEEE-1394 link and DirectDigitalDub DV-25 input,

Integrated USB controller.
