At the ninth SES Industry Days, currently taking place at the satellite operateror's Betzdorf Luxembourg Headquarters, SES and industry partners will demonstrate a number of technologies to broadcast Ultra HD with High Dynamic Range.

Today at the annual event it launches a 24/7 Ultra HD test channel for transmitting High Dynamic Range (HDR) content.

As the broadcasting industry is in discussions to establish a standard for HDR transmission, the goal of SES's HDR demo channel is to allow industry partners to test the various technology candidates. At the moment the channel carries Ultra HD content provided by LG Electronics, with a backwards compatible HDR technology called Hybrid Log Gamma (HLG). HLG HDR content will be demoed on LG's E6 4K OLED TV.

For the ninth edition of this event, SES, together with industry partners, will present and demonstrate several technologies for enhancing the quality of Ultra HD television with High Dynamic Range. This feature will be key for next generation Ultra HD picture quality, as HDR provides much higher contrast and offers a more realistic viewing experience.

Delegates of the event will be able to witness HDR implementations such as HDR 10, Dolby Vision, Hybrid Log Gamma and the Technicolor/Philips solution on state-of-the-art flat screens of major manufacturers.

Thomas Wrede, VP Reception Systems at SES commented, "High Dynamic Range will be a major improvement for satellite delivered Ultra HD television. As industry and operators now face the challenge of standardising and implementing a plethora of technology candidates, we intend to support the process with our test channel. At the same time, we have started to implement relevant HDR technology at our Munich playout facility."

LG demoed the HDR capabilities of its OLED TV at the SES ASTRA INDUSTRY DAY. The demo coincided with the launch of the SES Ultra HD Test Channel Displaying Hybrid Log Gamma HDR Content supplied by LG.

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 last 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. As the first flat-panel television with infinite contrast ratio and no backlight panels, LG OLED TVs are unrivaled in their ability to deliver an HDR experience like no other.

“LG has been at the forefront of television innovation for decades,” said Wayne Park, executive vice president and head of LG’s European operations. “We are committed to supporting the efforts of our partners to standardize HDR broadcast technologies and make advanced display technology more widely available.”

LG demonstrates HDR broadcast technology in France

LG Electronics said Sunday it demonstrated high-quality broadcasting technologies using its organic light-emitting diode (OLED) televisions in collaboration with a French state-run broadcaster last week.

The electronics maker said the demonstration, at the headquarters of France Televisions, has shown that its Ultra OLED televisions can display high dynamic range (HDR) pictures not only through satellite broadcasting but also on terrestrial channels.

"We plan to adopt more diverse HDR standards for our OLED televisions, aiming at boosting our presence in the super high-quality broadcasting market in Europe," LG Electronics said.

During last week's test broadcast, LG Electronics and France Televisions used an HDR standard called "Hybrid Log Gamma (HLG)."

Basically, viewers who do not have a television compatible with the HDR function cannot watch HDR broadcasts. This has made broadcasters transmit both ordinary and HDR versions of each program simultaneously. But with the HLG standard, viewers with a non-HDR television can receive the signal even when broadcasters send only the HDR signals, allowing the broadcasters to use frequencies more efficiently, LG Electronics said.

The HLG technology was chosen last year as the standard for satellite HDR broadcasts in Japan and has been considered a likely candidate for Europe's terrestrial HDR broadcast standard.

Besides HLG, LG Electronics said its Ultra OLED televisions support other HDR standards such as HDR 10 and Dolby Vision.
