Islamabad—LG Electronics (LG) is collaborating with the British Broadcasting Corporation (BBC) and satellite operator SES to host a demonstration of High Dynamic Range (HDR) broadcast technologies at the ninth SES Industry Days conference this week in Luxembourg. High quality HDR content will be transmitted to LG’s latest OLED TV via live satellite feed utilizing backward compatible HLG (hybrid log gamma) technology. HLG expands the contrast ratio and color reproduction capability of SDR TVs (Standard Dynamic Range). The HDR transmission demonstration by LG and the BBC will utilize SES Astra’s satellite network.
HLG technology was developed by the BBC and NHK to enable a backwards compatible transmission of HDR content. Employing a single distribution bit stream which can be decoded by both dedicated HDR receivers and legacy non-HDR receivers, the HLG system requires no production metadata, making it compatible with existing broadcast infrastructure, thereby enabling a straightforward migration to HDR television production.
The flexibility of the BBC’s innovative HDR HLG technology makes it an excellent choice for broadcast HDR services while SES’s new HDR test channel allows industry partners to test a variety of new display standards and content. Viewed on LG’s OLED TVs, HDR HLG content looks more realistic, delivers greater depth and the deepest blacks.
