Harmonic delivers multi-service, multi-platform HD encoder

Harmonic has extended its family of digital video compression solutions with the DiviCom Electra 7000 high definition (HD) MPEG-4 AVC (H.264) encoder. A multi-channel, multi-service HD H.264 encoder, the Electra 7000 supports up to four full resolution HD channels and can simultaneously create low resolution services for picture-in-picture (PiP) or multi-channel mosaic applications. The solution is geared towards satellite, telco/IPTV and cable operators, the Electra 7000 sets an improved benchmark for HD H.264 compression performance and video quality. Customers have confirmed bit-rates 20 to 30 percent lower than any currently deployed HD H.264 encoder, and the system has also been selected by five satellite and telco operators in North America and Europe to power their forthcoming HD services.

The Electra 7000 aims to address the challenge shared by all operators regarding how to minimize bit-rates while providing superior video quality as they expand their service portfolios to include additional HD programming, video-on-demand, personal video recorders (PVR), network PVR and other applications. Satellite operators can utilize the Electra 7000 to enhance the channel line-up by delivering substantially more national and local HD channels while improving picture quality. The Electra 7000 also revolutionizes the video-over-DSL business model by enabling telcos to provide outstanding HD and standard definition (SD) services with support for multiple televisions and PVR functionality in addition to making bandwidth available for competitive high-speed Internet access.

"Service providers no longer have to accept compromises on video quality or resolution for their HD services as they seek a solution that delivers on the promise of H.264," said Patrick Harshman, President and CEO of Harmonic Inc. "The DiviCom Electra 7000 leapfrogs the industry estimates for bit-rate improvement possible with H.264 and facilitates the widespread expansion of HD in the near future. With this next-generation system, Harmonic is building upon a longstanding tradition of excellence and technology innovation with the DiviCom encoders and taking HD compression to a whole new level."

The Electra 7000's compression engine is based on architecture that utilizes single slice video processing and other tools including advanced video pre-processing and full multi-pass LookAhead encoding. The encoder supports constant bit-rate (CBR) or variable bit-rate (VBR) encoding for all resolutions in 1080i and 720p formats, as well as native 5.1/7.1 audio encoding. In addition, it includes native IP outputs and can be incorporated into Harmonic's industry-leading DiviTrackIP distributed statistical multiplexing solution, further improving bandwidth efficiency.

The density provided by Electra's modular one rack unit (RU) platform aims to reduces capital and operating expenditure, conserve rack space and reducing power consumption in comparison with existing 1RU or 2RU systems supporting only one HD H.264 service. Operators can easily scale from one to four channels per encoder as demand for HD programming continues to grow. The Electra's multi-service capabilities also increase versatility by enabling service providers to deliver video to a range of devices and to support a variety of new applications including PiP, interactive program guides and multi-channel mosaics.
