DVB-T tune request parameters

I'm working in GraphEdit to capture video from a Pinnacle PCTV card, in preparation for writing a program that will do the same, among other things.

What, precisely, is the meaning of the tune request parameters? How do I find the appropriate values to use, and is there a way to do so automatically? (ie, not to have to manually change params in the final program when trying to watch DVB in different countries.)

Solution

  • TransEdit can help you find some parameters. The ONID you can find on dvbservices.com. As far as I know you need to be able to configure the following values:

    IDVBTLocator::put_CarrierFrequency()
IDVBTLocator::put_Bandwidth()
IDVBTuneRequest::put_SID()
IDVBTuneRequest::put_TSID()
IDVBTuneRequest::put_ONID()

    For the Bandwidth I was even able to use -1. But I have only tested two different countries in europe.
