I am unable to answer this question after reading the DVB API so I need some guidance. The DViCO FusionHDTV 3 Gold-Q card had two RF input connectors and the ability to select either one of them. There is no difference between the capabilities of the RF connectors. How does the application program select one or the other of these connectors, by that I mean what DVB API call is used by the application program? v4l handles this as another input. Does DVB support something like an antenna switch that might be an appropriate model for this situation? I do have a proposed solution, but I don't really like it. First some background. The Windows software provided by the card manufacturer pretends that the two inputs have different characteristics. It uses OTA and Cable in the provided interface program to select both the tuner channel frequency table and corresponding RF input. It makes some sense in that one RF connector is labeled ANT and the other is labeled CABLE. I prefer a general purpose interface so that either input can be used with either VSB or QAM. This is because cable TV can use either VSB or QAM. My proposed solution is to modify the current lgdt3302 driver to select the ANT input when 8VSB is selected or the CABLE input when QAM64 / QAM256 is selected. This is a small change. I look forward to getting your feedback on this. --Mac
