Hi all,
This patch adds ATSC support to VDR 1.7.4.
Klaus, would you consider adding this to VDR?

Am I right in understanding that ATSC is a "subset" of DVB-T?
How are ATSC transponders announced in the NIT? Shouldn't there also be some code in cNitFilter::Process() for this?

Although ATSC and DVB-T share some similarities, they are fundamentally different. For instance, the ATSC standard does not even define a NIT. The patch simply allows VDR to tune and view ATSC channels, the various tables are parsed by a plugin.
