SES tester Ultra HD transmission med H.265/HEVC
SES meddeler, at de som de første har gennemført tests af Ultra HD satellit transmission i H.265/HEVC standarden. Testen af Ultra HD med en opløsning på 3840×2160 blev gennemført på Astra 19,2 grader øst.
H.265/HEVC muliggør mere effektiv kompression op mod 50%, så transmissionen af Ultra HD signaler bliver mere realistisk.
SES demoen benyttede Harmonic’s ProMedia Xpress og et HEVC decoder reference-design system baseret på Broadcom’s BCM7445 enhed for at modtage HEVC komprimeret Ultra HD tv transmission. Signalet blev sendt via DVB-S2 med en data rate på 20 Mbps.
SES udtaler i forbindelse med testen. “We are very proud to present the first Ultra HD demo in the HEVC standard on satellite … broadcasting the first real Ultra HD picture in a commercially realistic bandwidth,” said Thomas Wrede, VP reception systems, SES. “We are convinced that the HEVC standard will become the option of choice for TV operators broadcasting Ultra HD content, and expect the industry to develop prototype Ultra HD receivers in the coming months.“

Luxembourg, April 19, 2013 – SES (NYSE Euronext Paris and Luxembourg Stock Exchange: SESG) announced today that, together with its partners Harmonic, the worldwide leader in video delivery infrastructure, and Broadcom Corporation, a global leader and innovator in semiconductor solutions, it has pioneered the first Ultra HD transmission in the new HEVC standard live from an ASTRA satellite at 19.2 degrees East. The HEVC standard features an up to 50 percent encoding efficiency improvement, compared to previous test broadcasts in MPEG-4 AVC (H.264).
The end-to-end demonstration which was presented at the SES Industry Days in Luxembourg used Harmonic’s ProMedia Xpress and a HEVC decoder reference-design system based on Broadcom’s BCM7445 device for receiving HEVC encoded Ultra-HD television transmission. The signal was broadcast in DVB-S2 using a data rate of 20 Mbit/s.
The live demonstration for the first time broadcasts a full 3840×2160 pixel Ultra HD picture in HEVC, while previous demonstrations were either broadcast in H.264 or using 4 HD pictures in parallel. SES first live-broadcast a full 3840×2160 pixel Ultra HD picture using the MPEG-4 AVC (H.264) standard at IBC 2012.
Thomas Wrede, VP Reception Systems, SES, said: “We are very proud to present the first Ultra HD demo in the HEVC standard on satellite. SES has once again taken a leadership role in the industry by broadcasting the first real Ultra HD picture in a commercially realistic bandwidth. We are convinced that the HEVC standard will become the option of choice for TV operators broadcasting Ultra HD content and expect the industry to develop prototype Ultra HD receivers in the coming months. With this initiative SES will be significantly driving the Ultra HD ecosystem forward and provide a 24/7 test channel to its industry partners.”
Ian Trow, Senior Director of Emerging Technology and Strategy, Harmonic, said: “SES has achieved an important industry first with Harmonic and Broadcom. This DVB-S2 transmission clearly demonstrates the benefit of HEVC encoding using the Harmonic ProMedia in a live to air Satellite application. A significant compression improvement has been achieved using HEVC when compared to previous Ultra HD deployments using MPEG-4 AVC (H.264).”
“Broadcom is working to advance the adoption of HEVC technologies – and ultimately the distribution of UltraHD content – with SES,” said Joseph Del Rio, Broadcom’s Associate Product Line Director, Broadband Communications Group. “HEVC is the catalyst that will drive UltraHD television with its telepresence-like resolution to consumers.”
