ComputeSuggestedChannelNum()

QString ChannelImporter::ComputeSuggestedChannelNum ( const ChannelInsertInfo &  chan )

staticprotected

Compute a suggested channel number that is unique in the video source. Check first to see if the existing channel number conflicts with an existing channel number. If so, try adding a suffix starting with 'A' to make the number unique while still being recognizable. For instance, the second "7-2" channel will be called "7-2A". If this fails then fall back to incrementing a per-source number to find an unused value.

Parameters

chan	Info describing a channel

Returns

Returns a simple name for the channel.
