SES Delivers 8K TV Transmission


GER: SES has broadcast, for the first time, an 8K television signal via its satellite system during the two-day SES Industry Days event in Luxembourg. 
In the demo broadcast, uplink signal transmission was successfully supported by the new R&S PKU amplifier from Rohde & Schwarz.
Using the DVB S2X standard, SES transmitted the 8K TV signal on a single 36 MHz transponder via its Astra 3B satellite. The demo video, with a resolution of 7680 x 4320 pixels (8K), which is four times higher than for a 4K signal, was encoded in HEVC and transmitted at a rate of 80 Mbit/s. The 8K content was broadcast with a frame rate of 60 frames per second and 10-bit colour depth. In addition, a native IP-formatted signal was used to learn about the requirements to be met for a fully IP-based broadcast infrastructure.
The Rohde & Schwarz R&S PKU amplifier was used to send the HEVC encoded signal to the satellite. The R&S PKU combines the best of two worlds in a single device: the strengths of solid-state amplifiers and the compactness and low weight of tube amplifiers. If individual transistors fail, for example, the amplifier continues operating at reduced power. It features adaptive linearization for improved signal quality, enabling network operators to transmit significantly more data using the same signal bandwidth – ideal for 8K transmission.
Thomas Wrede, Vice President, New Technology & Standards at SES Video, said: "Even though 8K resolution is not yet commercially relevant, we have shown that our satellite network is able to deliver 8K content. We are proud to provide an insight into the future of television. Rohde & Schwarz has made a valuable contribution to this achievement."
