8K HDR satellite broadcasting a commercial option?

Samsung, a South Korean tech heavyweight, has successfully tested 8K HDR broadcasting using KT Skylife’s H.265 standard last week, according to an official statement released by KT Skylife, a subsidiary of KT Corporation.

The test was conducted at Mokdong Broadcasting Centre in Seoul, where Cheollian Satellite’s Ka-band was used to receive and transmit 8K imageries to Samsung QLED TV in the latest HDMI standard and in real-time.

Cheollian Satellite is part of South Korea’s Electronics and Telecommunications Research Institute (ETRI).

Lee Hyo-gun, vice-president of the video display business division of Samsung Electronics, said: “In 2019, 8K QLED supports the latest HDMI standard and can now seamlessly receive and play ultra-high-definition (UHD) 8K content.”

With the use of high-efficiency image compression method, H.265 standard is 50% more efficient in compressing video data as compared with the H.264 standard. Furthermore, DVB-S2x improves satellite transmission by expanding satellite transmission band from 65Mbps to over 100Mbps; the success of the demonstration not only turns 8K HDR satellite broadcast into a reality but also a commercially viable option.

KT Skylife stated: “This test broadcast is meaningful because it confirms the technical stability of high-capacity super-HD satellite broadcasting.

“We will continue to co-operate with domestic and international experts to upgrade satellite UHD technology.”

Lee added: “We will further strengthen our 8K market leadership.”
