Solution Spotlight: Video Compression

Today’s broadcaster is migrating from the traditional function of creating and distributing a single analog channel, to a new world of delivering multiple versions of multiple channels through many different delivery systems. Nationwide multiplexes of multichannel HDTV content, 3DTV programming, innovative datacasting services — the revenue-generating possibilities are numerous.

But the opportunity also presents challenge: How do you deliver a great picture on several channels simultaneously — in the same constrained quantity of bandwidth to the home? Achieving this requires compression technology that not only enables more efficient use of bandwidth, but also reduces the signal degradation that results from repeatedly compressing and decompressing signals.

The Harris Selenio media convergence platform combines baseband processing, compression (MPEG-2 and H.264) and networking functionality within a single, 3RU solution. An integrated 10-bit, H.264 4:2:2-capable contribution encoder ensures exceptional picture quality at the low bitrates that enable multichannel broadcasting within the valuable digital terrestrial spectrum.
