Fujitsu Microelectronics America Inc. has announced a large-scale IC capable of real-time compression and decompression of HDTV-level video in H.264 format. Touted to be the industry's first, the MB86H50 is based on an H.264 processing algorithm developed by Fujitsu Laboratories Ltd. The IC is designed with Fujitsu's high-performance audio and video processing technology and will be manufactured using the company's 90nm process technology.

The MB86H50 also 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 products such as portable A/V products, hard disk recorders and home network equipment.

"The MB86H50 represents a major breakthrough in video processing, applying the highly efficient H.264 standard in high-profile applications for the first time," said Davy Yoshida, director of business development, FMA. "Because H.264 encodes video so much more efficiently than MPEG-2 or MPEG-4 part 2, H.264 allows more TV programming in a specific channel bandwidth. The new format also enables high-quality video to be delivered over bandwidth-limited networks. Our new device will bring these capabilities to a new generation of CE equipment."

Real-time compression, decompression
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, the company said.

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

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.

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.
