DVB-T tune request parameters

开发者_Python百科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.)

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.
