Broadlogic, a start-up based in San Jose, California unveiled its massively parallel, multi-channel video processor to help cable operators (MSOs) reclaim over 450MHz of bandwidth and scaling access network performance to fiber-like levels.
BroadLogic said its new BL80000 TeraPIX chip is designed for a new generation of Residential Gateway installed outside or just inside a residence This allows the network to be all-digital, while subscribers continue to receive the cable-ready analog video, digital video, high speed data and voice services inside the home. A digital program uses one-tenth the space of a an analog program. Most cable operators typically deliver an 80-or-so channel lineup of the most popular broadcast and cable channels using analog. Because these channels are delivered in analog format, not digital, they take up a disproportionate amount of an operator’s bandwidth (500MHz of a typical 750MHz network).
With an all-digital network and 750 MHz capacity would enable 4.5 Gbps to the home.
However, going all-digital requires subscribers to install a digital set-top box and remote for every cable-ready device in the home. This solution is both costly for operators and undesirable to many subscribers.
The BroadLogic TeraPIX video processor works by decoding bandwidth-conserving digital video signals delivered by a cable operator, and generating 80-plus high-quality channels of television. Cable operators get their extra bandwidth, and consumers get the channel lineups they’re used to without having to get more set-tops, run more coax, or lose more remotes. The TeraPIX processor enables solutions that support virtually all existing analog and digital consumer devices. For example, if a subscriber has a DVR set-top from their cable operator, the digital signals are passed through TeraPIX to the DVR.
BroadLogic is sampling the TeraPix now.
