Intel unveils dual-channel TV demodulators. intel dual channel tv demodulators. Intel has unveiled its first digital TV dual-channel demodulators housed on a single piece of silicon for the consumer electronics (CE) market segment. The new Intel CE 6250 dual-channel COFDM demodulator and CE 6251 dual-channel diversity-enabled COFDM demodulator expand Intel’s CE offerings by allowing manufacturers, such as UK CE manufacturer TVonics, to deliver highly integrated advanced digital home entertainment capabilities for a variety of future consumer entertainment devices, such as personal video recorder set-top boxes (PVR STB......

The major chips in Broadcom's reference design are the BCM3250 set-top box single-chip front end (dual QAM demodulators, DOCSIS 1.1 capable MAC, DAVIC 1.2/1.5 MAC) and the BCM7030 video decoder chip (dual SD or HDTV, transport, MPEG2 decoder, and 2D/3D graphics). ...
