Harmonic Unveils Enhanced ProStream 4000 Multiscreen Transcoder
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. 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. ProStream 4000 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.
In terms of H.264 compression, Harmonic has implemented LookAhead and VBR technology enhancements specifically engineered for adaptive streaming delivery. Additionally, the ProStream 4000’s new multimachine synchronization capabilities improve the HD multiscreen viewing experience.
“Harmonic continues to enhance its solution offerings that enable service providers and content creators to meet the growing demand for Internet and mobile video services,” says Thierry Fautier, senior director, convergence solutions at Harmonic Inc. “Our award-winning ProStream 4000 is a powerful, versatile solution for live transcoding to multiple screens, with support for a variety of ecosystems, and includes technology advances that effectively address streaming quality to significantly enhance Internet and mobile TV services.”
Harmonic has also integrated ProStream 4000 with industry-leading CDNs for a variety of adaptive streaming and legacy protocols. A new open Key Management System (KMS) interface allows operators to connect to multiple DRM systems. The ProStream 4000 also boasts improved carrier-grade management capabilities through support for N+M redundancy and Harmonic’s NMX software for network monitoring and control.
The ProStream 4000 will be on display at Harmonic’s stand 85 during the IP&TV World Forum, March 22-24 in London. The ProStream 4000 will also be on at the 2011 NAB Show in Las Vegas, April 11-14, in booth SU4909. The company’s line of production and playout solutions will be on display in booth SL2005 during NAB.
