High Definition

For cable operators, the DiviCom® MV 500 MPEG-2 HD encoder offers a best-in-class solution for HD services. As opposed to rate shaping which can result in a degradation of video quality, the MV 500 makes it possible for cable operators to deliver as many as four HD programs within a single 256-QAM channel.

For MPEG-4 AVC (H.264) architectures, Harmonic’s latest generation Electra™ 7000 HD encoder leapfrogs the industry estimates for bit-rate reductions possible with H.264—generally considered in the range of 50% compared to MPEG-2 HD—by delivering high quality video in the range of 3-8 Mbps depending on the type of content and resolution selected. Beyond the performance and quality benefits, the Electra is also a multi-channel, multi-service encoder capable of delivering up to four full and low resolution channels in 1RU for applications including PiP, enhanced program guides and multi-channel mosaics.
