Broadcom offers SoC tuner for satellite set tops

US chipmaker Broadcom has declared open season on every type of tuner with its Full Band Capture technology which can address over 1 GHz of spectrum in one go. It now has a version for IBC that can search and tune the satellite TV spectrum from 950 MHz right up to 2150 MHz. The technology was first introduced in June with a cable version which shifts all tuning into a single chip up to 1GHz and it can tune lots of TV channels at once all along this spectrum.

The new BCM 4528 also uses FastRTV fast channel change technology which it reads the I-Frames in the neighboring channels in readiness to render that channel in a couple of 100 milliseconds. The approach cuts between 8 and 9 components out of a set top and we expect more announcements at IBC to close up the considerable lead which Broadcom has opened in tuners.

The DOCSIS data over cable technology also uses multiple tuners and Broadcom in June also included FBC in a DOCSIS modem and will now be aggressively chasing that market.
