In the UK we have a number of DVB-T and DVB-T2 channels which are part time, that is, they broadcast for only part of each day. During the times when they are not broadcasting, their bandwidth in the MUX is used by another part-time channel. This morning I tried to start live TV on the part-time channel which I had been watching last night, but which was not broadcasting this morning (I did not realise this until afterwards). I then had a very long wait, during which it seemed that MP had got stuck, but it did eventually timeout.
I compared MP with the behaviour of my Humax PVR:
(1) On the Humax, tuning from one active DVB-T2 channel to another active DVB-T2 channel takes 4 seconds.
Tuning from one active DVB-T2 channel to an inactive DVB-T2 channel takes 10 seconds. After this period, the Humax displays a panel indicating when that channel is on-air (so this must be obtained from the broadcast data stream in some way).
(2) On my HTPC using MP with TBS 6284 tuner cards, tuning from one active DVB-T2 channel to another active DVB-T2 channel takes 4 to 5 seconds (so similar to the Humax).
Tuning from one active DVB-T2 channel to an inactive DVB-T2 channel takes 140 seconds, after which the screen shows "Unable to start time shifting; no video detected". During this period MP is unresponsive, so it is not possible to tune to a different channel until the timeout expires.
Is it not possible for MP to detect quickly that a channel is not currently broadcasting, even though the MUX containing that channel is being received with normal signal strength? Are there any TV Server settings that could reduce this timeout? Thanks.
I am using MP 1.9.0 pre, with aMPed skin, on 32-bit Vista.
