SAN JOSE, Calif. — April 3, 2014 — At booth SU1210 at the 2014 NAB Show, Harmonic (NASDAQ: HLIT), the worldwide leader in video delivery infrastructure, will demonstrate the world’s first end-to-end HEVC solution for delivering live 2160p60 10-bit Ultra HD content. In collaboration with companies including Broadcom Corporation, Sigma Designs, Vigor Systems, and ViXS, the Harmonic broadcast workflow supports the delivery of live, linear playout, and VOD Ultra HD content to consumer-grade TVs and set-top boxes (STBs).

“Harmonic is making Ultra HD a reality by offering the broadcast community an end-to-end solution for UHDTV content preparation and delivery,” said Thierry Fautier, vice president, solutions and strategy at Harmonic. “At NAB, Harmonic will demonstrate how broadcasters can use our integrated video compression, storage, and delivery solutions to deliver 2160p60 10-bit content based on current joint EBU/DVB/SMPTE recommendations using consumer-grade technologies for decoding, connectivity, and display on Ultra HD TV sets.”

Highlights include:
• The first consumer-grade demonstration showing live streaming of Ultra HD content, based on Harmonic’s market-leading HEVC encoding technology and the XCode 6400, a 2160p60 10-bit SoC from ViXS Systems, used to decode and display live content to a UHDTV via HDMI 2.0.
• An end-to-end solution for delivering 2160p60 Ultra HD VOD content over IP networks featuring Harmonic’s ProMedia^® Xpress high-performance transcoder with HEVC support, sent by the WFS™ file-based workflow engine to a MediaGrid shared storage system, and streamed using the ProMedia Origin streaming video server to consumer devices in the MPEG-DASH format.
• A 2160p60 Ultra HD linear playout workflow featuring Harmonic’s WFS, ProMedia Xpress, and MediaGrid solutions integrated with an Advertio transport stream playout platform from Vigor Systems, to deliver an Ultra HD linear channel.
• An Ultra HD 120-Hz broadcast workflow, powered by Harmonic ProMedia Xpress, frame-rate upconverted on Sigma Designs’ high-performance and cost-effective 120-Hz UHDTV platform. Sigma Design’s UHDTV platform is comprised an UHDTV SoC that enables HEVC decoding (STV7603), and an innovative motion judder removal and frame-rate conversion SoC (FRC8000) for providing the best picture quality on large screen displays.
• The first standard-compliant, live 4K Ultra HD broadcast workflow, powered by Harmonic ProMedia Xpress transcoding and decoded by Broadcom’s BCM7445 Ultra HD video decoder solution.
