Sony and SKY Perfect JSAT jointly demonstrated a live simultaneous 4K-HDR and HD-SDR broadcast at Inter BEE 2016 at Makuhari Messe, near Tokyo.
SKY Perfect JSAT's Tokyo Media Center produced and broadcasted in both 4K-HDR (3826x2160) and HDR-SDR (1920x1080). TV sets at the Sony booth presented both 4K and HD versions; the 4K broadcast via JSAT's satellites and presented on a BRAVIA TV, while the HD was transmitted via the Internet.
The demonstration showcased the capability of Sony's "SR Live for HDR," a solution for achieving efficient 4K-HDR production and developing effective workflows to support the advancement of 4K broadcasts.
To date, broadcasters interested in 4K-HDR production have faced the need to configure a separate production system for each 4K-HDR and HD-SDR - a cumbersome approach requiring large-scale setups. The 'SR Live for HDR" solution integrates the two systems, enabling efficient workflows and streamlined configurations.
The solution employs the HDRC-4000 HDR production converter unit to enable use of the Sony's recommended 4K-HDR S-Log3/BT.2020 format, supporting a system that delivers broadcast EOTF conversion with no loss of live image quality.
SKY Perfect JSAT began broadcasting 4K-HDR in October, and is moving ahead with plans to advance into live broadcasting of sports and other events with support from Sony.
