Description
A MythTV DVB channelscan creates a list of channels with channel numbers defined by the Logical Channel Descriptors in the NIT. A DVB-C capable HDTV processes also the HD Simulcast Logical Channel Descriptor which defines the correct channel number for channels that are transmitted both in SD and in HD quality.
For instance, MythTV puts channel "NPO 1" at number 1 and channel "NPO 1 HD"(HD version of the same channel) at number 925. My DVB-C TV does the opposite; channel "NPO 1 HD" is at number 1 and channel "NPO 1" is at number 925.
The attached patch does add the processing of the HD Simulcast descriptors. The result is a channel list that is identical to that of my TV. This is tested with the DVB-C signal of operator Ziggo in The Netherlands.

Note that the patch set also contains one unrelated modification; the statement "info.is_opencable = true", executed when an SCTE Registration Descriptor is seen, is commented out. In the Ziggo DVB-C signal there are SCTE Registration Descriptors in about 10 channels but it is not correct to classify these channels as opencable instead of DVB.

Support for HD simulcast logical channel numbers is already implemented in tvheadend in 2015, see https://tvheadend.org/issues/2610
