Synopsis

Intro Mike: On November 6, 2006, BroadLogic Network Technologies, a San Jose chip manufacturer, announced The World's First Massively Parallel, Multi-Channel Video Processor, a terapixel-speed video processing chip that will allow cable providers to recover bandwidth that can then be used to deliver more high definition channels, video on demand and high bandwidth data services without major network upgrades.   Mike: Gordon, before we discuss the Boradlogic product, can you give us an idea of how current cable delivery systems work?   Traditional cable delivery systems work by allocating 6MHz of analog bandwidth for each channel. Most cable providers offer approximately 80 channels that consume (6 MHz/channel x 80 channels) 480 MHz of bandwidth. Typical cable networks provide only 750 MHz of bandwidth and with 480 MHz used for video, there is not much left for other services.   Let's think about this a little bit more - one channel consumes 6 MHz of bandwidth but it takes 480 MHz
