Harmonic Wows NAB Crowds with HEVC Compreion Demo Showing Ultra HD to Be Realistic Upgrade to HD

Date:

Wednesday, April 10, 2013

Harmonic (NASDAQ: HLIT), the worldwide leader in video delivery infrastructure, announced today that its comprehensive demo consisting of HEVC compressed Ultra HD content in a variety of real world scenarios is proving popular with NAB Show attendees. The demo shows Ultra HD to be viable at bandwidths currently used for HD, using the new HEVC (H.265) standard instead of the predecessor AVC (H.264). Ultra HD content is shown using HEVC at 3-7 Mbps using a Broadcom Ultra HD HEVC chipset decoder. Alongside this, a software decoder from NTT Docomo is shown to demonstrate Ultra HD HEVC decoding for the increasingly important multiscreen market.

While native Ultra HD content is the ideal, the demo also outlines the benefits of Harmonic's superior preprocessing when upconverting HD content for display on an Ultra HD screen, said Ian Trow senior director of emerging technology and strategy at Harmonic. The benefits of the ProMedia adaptive bit rate multiscreen platform used for HD compression yields significant quality gains when compared to legacy HD content similarly upconverted to Ultra HD.

Format Leadership

Harmonic technology and solutions powered the world's first large-scale, OTT multiscreen trial based on DASH, as well as an implementation that's expected to be the first commercial DASH service. The addition of HEVC and Ultra HD support to the ProMedia family continues the company's format leadership. HEVC, which offers up to 50 percent better compression efficiency than H.264, is being demonstrated at NAB on the ProMedia Live real-time and ProMedia Xpress file-based transcoders.

The HEVC Ultra HD compression demo, ProMedia, and other products from Harmonic can be seen at the NAB Show in booth SU1411. Further information about Harmonic is available at www.harmonicinc.com.
