The MB86H50 video processing IC from Fujitsu Microelectronics America Inc. has been designed for real-time compression and decompression of high-definition TV-level video in H.264 format.

Scheduled for March 2007 availability, the MB86H50 supports the H.264 High Profile, Level 4.0 standard used in next-generation DVDs. It enables high-resolution recording, playback and transmission of high-definition video on audio-visual products such as portable A/V products, hard disk recorders, and home network equipment.

The new video-processing IC is capable of real-time compression and decompression of high-definition video, with a maximum up to 1440 dots x 1080 lines. The sound is simultaneously compressed and decompressed in Dolby Digital format. This is the first time these processing features have been integrated onto a single chip for general use, according to Fujitsu.

The MB86H50 uses the H.264 format to address the higher functionality required for advanced recording and playback of high-resolution, high-definition video, with the associated requirement for compressing large volumes of data. The chip uses proprietary compression technology developed by Fujitsu Laboratories to reduce processing loads, and incorporates Fujitsu's embedded memory technology. Fabrication using Fujitsu's 90nm manufacturing process technology will enable a compact size and low-power operation.

This device is said to be the first H.264-supportive LSI featuring two pieces of embedded 256Mbit FCRAM. The optimized design combines logic and memory on one LSI chip, enabling a more compact size and lower power consumption.

Self-tuning algorithm
The new chip has a proprietary "self-tuning" algorithm developed by Fujitsu Laboratories that automatically applies a lighter compression method to high-action zones where compression artifacts are most noticeable, such as human faces or slow-moving objects, and stronger compression method in other zones. This enables image data size to be reduced to one-half to one-third that of the MPEG-2 format with an equivalent level of image quality.

Fujitsu will continue to enhance the high functionality of the MB86H50 to support full high-definition capabilities up to 1920 dots x 1080 lines. Fujitsu will enrich its line of video-processing chips, including products such as a "multi-decoder" chip that can handle multiple formats, including both H.264 and MPEG-2.

Scheduled for introduction in March 2007, the MB86H50 will be packaged in 650-pin FBGAs and priced at $120 each in sample quantities. Volume pricing is available upon request.
