NTT West, a subsidiary of Nippon Telegraph and Telephone Corporation, is performing streaming trials hoping to start using 4K-resolution standard in videos online and television. Though 4K-resolution is not something new and is already available in the market, it is not yet used as a standard resolution system in mainstream broadcast and film media, most of which still rely on megapixels, including the 1080p. NTT West’s tests will end on Friday.
4K resolution can provide four times better details compared to 1080p high-definition. The idea of its usage is to transmit detail materials by compressing technology without losing its image quality. As what is currently used, videos are transmitted using pixels for each frame and are put together as if puzzles. Through 4K resolution, videos are transmitted without the need for standard pixel consideration, using algorithms that analyze the colours distributed throughout an image so that no unnecessary information will be kept or included in the broadcast.
Osaka-based NTT West operates in the western regions of Japan with 6 regional headquarters and 33 branches. The Japanese government also owns some shares of the Nippon Telegraph and Telephone Corporation, NTT West’s mother company. Japan, in time for the FIFA World Cup, aims to be the first country to broadcast using 4K resolution next year.
