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.
Super Hi-Vision is an ultra-high-definition video format being developed by NHK for next-generation TV broadcasting, with a resolution of 7,680?4,320 pixels.
The new codec equipment was delivered as a prototype to NHK Science & Technology Research Laboratories. Aiming for practical implementation of SHV broadcasts in the future, NHK Science & Technology Research Laboratories is expected to further enhance its R&D efforts to make SHV video transmission systems more compact while delivering better video quality with higher stability.
The codec equipment utilizes the H.264 encoding format that can ompress the vast amounts of image data that SHV produces at a rate of 60-frames per second (fps), a world's first, enabling efficient transmissions via broadcasting networks or IP connections. Compared to existing equipment, this new device achieves double the compression efficiency, and due to more efficient inter-frame predictive processing, it 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.
An SHV video transmission system utilizing Fujitsu's codec equipment will be on display at the "SHV High-efficiency Video Encoding Equipment" booth of the Open House 2010 hosted by NHK Science & Technology Research Laboratories, from May 27-30. |
