Harmonic has announced enhancements to its carrier-grade ProStream 4000 multiscreen transcoder optimized for adaptive streaming applications that enable operators to meet growing demand for OTT and mobile TV services, while improving the video viewing experience. New capabilities include increased scalability, premium H.264 video encoding, multi-encapsulation, and expanded compatibility with a range of content distribution networks (CDNs) and digital rights management (DRM) software. This solution is easily integrated into existing video infrastructures, and can be controlled and monitored through Harmonic’s NMX Digital Service Manager.

To manage the complexity of multiscreen and OTT applications, ProStream 4000’s high-density configuration now supports the simultaneous processing of up to 48 video inputs and 48 legacy mobile phone, 18 iPhone, 12 SD, or four transcoded HD video outputs per single rack unit (1-RU). The ProStream 4000’s new built-in multi-encapsulation feature enables operators to encode once and encapsulate to a variety of target video formats, such as Apple HTTP Live Streaming, Microsoft Smooth Streaming, and Adobe HTTP Dynamic Streaming, as well as multi-bitrate transport streams for NDS and Widevine Adaptive Streaming.

Since its introduction, the ProStream 4000 has been successfully deployed for new Internet and mobile TV services by leading satellite, telco, cable, and broadcast operators in North America; major cable, telco, and mobile operators in Europe; and a key CDN operator in the Middle East.

The ProStream 4000 will be on display at Harmonic’s stand during the IP&TV World Forum March 22-24 in London.
