The Fusion HDTV III Gold QAM is based off of Conexant's newest signal-decoder chip, the CX23882. Conexant has long been the industry standard when it comes to tuner cards. Their newest line of chips, is what allows the reception of QAM signals. Working together with the decoder chip is a Tecmic tuner chip. Since ATSC signals use standard UHF frequencies, the tuner portion of the card is nothing entirely special. The card has two RF inputs, one is for CATV and one for Over-The-Air. There is also an S-Video port and an Audio input which can be used to capture video from a Digital Cable Box, Camera, Playstation, etc. It can also be used to scale and upconvert video from an S-Vid or Composite source to hi-res. The S-Video port can be made into a composite port with a simple S-Video to Composite adapter.
