Harmonic Facilitates Improved Channel Lineup and Video Quality for KWHY-TV in Preparation for ATSC 3.0

SAN JOSE, CA--(Marketwired - April 11, 2016) - Harmonic (NASDAQ: HLIT), the worldwide leader in video delivery infrastructure, today announced that KWHY-TV, the Spanish-language television station in Los Angeles, has deployed a comprehensive solution from Harmonic to broaden its channel lineup. Using Harmonic's Electra™ X2 advanced media processors, ProStream^® 9100 high-density stream processors and NMX™ Digital Service Manager video network management application, provided by Harmonic platinum reseller Heartland Video Systems, the station has successfully added additional SD subchannels to its original HD channel offering. Featuring a scalable architecture, the latest technologies for statistical multiplexing, and ATSC 3.0 support, Harmonic provides KWHY with a seamless growth path while improving bandwidth efficiency and video quality at a low total cost of ownership.

"In the ATSC environment, bandwidth is at a premium. Providing an enhanced news and entertainment lineup while maintaining the desired level of video quality is challenging without an advanced encoding solution," said David Gray, vice president of engineering at KWHY. "Harmonic offers a complete ATSC solution that features world-class video compression algorithms and multi-pass encoding technologies, allowing us to deliver the new services while hitting all of our quality benchmarks."

Harmonic's market-leading Electra X2 advanced media processors are being used by KWHY for high-quality, low-bandwidth MPEG-2 encoding of SD and HD video content. Powered by the Harmonic PURE Compression Engine™, the media processors support MPEG-2, AVC and HEVC.

Tight integration between the Electra X2 processors and ProStream 9100 stream processors with DiviTrackIP™ statmux technology maximizes the efficiency and flexibility of KWHY's statistical multiplexing operations. Through the ATSC solution, the television station can support one HD and seven SD channels per pool in order to increase bandwidth efficiency. Using a combination of Electra and ProStream for statistical multiplexing has enabled more services and enhanced video quality for KWHY. Additionally, Harmonic's DiviTrackIP technology provides geographic extensibility if KWHY participates in a channel sharing agreement with other stations in its market.
