Silicon Integrated Systems is best known for its southbridge solutions, at least one of which is likely within the PC you're currently using. For whatever reason, the company has decided to try its hand in the HDTV market by announcing its very own ATSC HDTV SoC chipset. The SiS328 chipset is designed to be implanted in LCD TVs in order to bring ATSC tuning capabilities to an otherwise vanilla monitor. The chip features the company's Digital Nature Video Engine (DNVE) technology, a dual-input HDMI 1.3 receiver, 3D comb filter, two USB 2.0 ports, five analog audio stereo inputs and everything else necessary to deliver ATSC tuning to an LCD TV. There's no indication of which TV makers (if any) are taking SiS up on its new offering, but the chip will be available for shipment starting in early Q2.
