I vote for a mechanism with a touch timestamp (which is set when the channels if announced). Channels which are not touched for a certain time and are not used otherwise e.g. by a pending timer could be removed.
What if you have EPG scan enabled? Doesn´t the card touch all channels?
There has often been a discussion on how to determine channels that don´t exist anymore, and I don´t have much idea about it. So I say sorry for this basic question, but, what happens if a channels stops transmission? Doesn´t it have no more audio and video PIDs transmitted? So can´t I simply delete channels where the audio and video PID can´t be determined anymore?
May be "touched" is a bit misleading. What I mean is "channels which aren't announced in SI data".
