Television's viewing experience continues to improve making it more visually pleasing and intense with each iteration, currently reaching the pinnacle of 4K HDR (High Dynamic Range). To accommodate their 4K HDR viewers with this level of technology SKY Perfect JSAT Corporation will reveal their first 4K HDR broadcast on October 4, during timeslots on its dedicated 4K channel SKY PerfecTV! 4K Experience, which was launched on May 1, 2016. The channel is free of charge by those who receive SKY PerfecTV! Premium Service or SKY PerfecTV! Premium HIKARI Service. 

The first 4K HDR broadcast is a program jointly produced with the Imagica Robot Group which will air in 4K HDR along with all five episodes of the BS SKY PerfecTV! drama “Kera (Yakubyo-gami Series)” that stars Kazuki Kitamura and Gaku Hamada. 

4K HDR broadcasts have a wider dynamic range, especially in the contrast between light and dark imagery, that provides more true-to-life depictions. For its 4K HDR broadcasts, SKY Perfect JSAT adopted the Hybrid Log-Gamma (HLG) standard, which was co-developed by the public broadcasters NHK (Japan Broadcasting Corporation) and BBC (British Broadcasting Corporation). While there is a variety of HDR techniques, HLG was developed as the most suitable format for broadcasting and HLG became an international standard in July this year. 

In response to the October launch of 4K HDR broadcasts, a software update for Toshiba’s 4K Regza Z20X series is scheduled to become available for download from late August. For information on downloading software, please visit the Toshiba Regza website:  (Japanese version only)
