ATEME Supplies Encoders for NHK's "Super Hi-vision" Project

ATEME's encoding technology was selected for use in the first public Ultra HD demonstration with MPEG-4 AVC (H.264) by NHK in Tokyo.

NHK's prototype Super Hi-vision (Ultrahigh-Definition Wide-Screen System) technology uses a video format with 7680 x 4320 pixels (16 times higher than standard Hi-vision, NHK's HDTV system). Super-fast cameras capture data at a rate of 4,000 frames per second and the audio component is 22.2 (as compared to today's 5.1 surround sound). A full specification for Ultra HD is expected by 2009, satellite transmission tests are predicted in 2011, and by 2020, NHK hopes that Ultra HD will be ready for broadcast to households.

ATEME said 18 minutes of uncompressed Ultra HD footage consumes 3.5 terabytes of data and one minute of uncompressed footage consumes 194 gigabytes. The use of ATEME's MPEG-4 AVC compression technology significantly reduces these requirements.
