Fujitsu Develops Super Hi-Vision Encoder for NHK

Fujitsu has developed codec equipment for systems transmitting Super Hi-Vision (SHV) video, with resolution 16 times higher than Japan's current Full Hi-Vision video. SHV offers a resolution of 7,680 x 4,320 pixels. This compares to 1,920 x 1,080 pixels for 1080p HD.

The new codec equipment was delivered as a prototype to NHK Science & Technology Research Laboratories. The codec equipment utilizes the H.264 encoding format and can efficiently compress SHV video at a rate of 60-frames per second (fps), a world's first, for transmission via broadcasting networks or IP connections.

Compared to existing equipment, Fujitsu said its new device achieves double the compression efficiency, and due to more efficient inter-frame predictive processing, also results in higher video quality for the whole system. The improved compression efficiency allows the video to be transmitted using lower bandwidth, thereby reducing the line costs and making a significant contribution towards the practical implementation of SHV video transmissions.
