Japan’s SkyPerfect JSAT pay-TV operator is to offer Ultra-HD transmissions in High Dynamic Range to its DTH subscribers.
SkyPerfect is already transmitting UHD signals via its JCSAT-3A satellite. The broadcaster will demo the new signals at the Tokyo InterBee Broadcast Equipment event on November 18th – 20th.
For the 4K HDR transmission, an uplink using existing facilities at the SKY Perfect JSAT Tokyo Media Center (TMC) will be sent from the JCSAT-3A communication satellite to the Inter BEE venue. Programming will consist of a variety of prerecorded SKY Perfect JSAT HDR video content and live TMC studio programmes. The 4K HDR format itself uses a Hybrid Log-Gamma (HLG) system, jointly developed by Japan’s public broadcaster NHK and the BBC and standardised by the Association of Radio Industries and Businesses (ARIB).
HLG is widely considered to offer a distinct advantage in that it is backwardly compatible with older digital transmission technologies.
