Harmonic’s Electra X2 advanced media processorsFREMONT, CA: Harmonic, a video delivery infrastructure for television and video services, announces the deployment of a comprehensive solution to KWHY-TV, the Spanish language television station, to widen its channel lineup. The station has additionally included SD sub channels to its original HD channel using Harmonic’s Electra X2 advanced media processors, ProStream 9100 high density stream processors and NMX Digital Service Manager video network management application. The harmonic solution features latest technologies for statistical multiplexing, and ATSC 3.0 support and enhances bandwidth efficiency and video quality.

KWHY enables harmonic’s Electra X2 for high quality, low- bandwidth MPEG-2 encoding of SD and HD video content. The Process also supports MPEG-2, AVC and HEVC and is powered using Harmonic PURE Compression Engine. KWHY leverages the efficiency and flexibility of statistical multiplexing operations, through a seamless integration between Electra X2 processors and ProStream 9100 processors with DiviTrackIP technology.

The ATSC solution allows television stations to support one HD and seven SD channels per pool, increasing bandwidth frequency. In addition, participating in channel sharing agreement provides geographic extensibility to KWHY through Harmonic’s DiviTrackIP technology.

Harmonic’s NMX video network management service controls the Electra and ProStream solutions, providing mass configuration, monitoring and automated frequency in centralized or distributed architectures. Further the KWHY upholds a hybrid mix of ATSC 1.0 and ATSC 3.0 operations under one control system.

“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. 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,” says David Gray, Vice President of Engineering, WHY.
