The SiS301LV is a Display device which has two data operation paths. Channel B path is selected when
SiS301LV performs TV or LCD only display function. There’s scaling hardware in this path. In LCD display
mode, this hardware can make lower VGA resolution display to fit up to 1280x1024 LCD panel. In TV display
mode, this scaler can provide overscan and underscan option for TV. At TV and LCD simultaneous display
mode, TV data stream run through Channel B and LCD data stream run through Channel A.
