[mythtv-users] BBC THREE/FOUR

[Malcolm Smith]

Simon,

Although I agree with point about the loops and the general behaviour of 
the DVB code (and feel free to fix!), I think your problem is slightly 
different.

The "channel" always transmitts it's either CBBC / C Beebies or 
BBC3/BBC4. The crafty b*****rs at the beeb do the following


scan results when THREE is off the air
BBC 
THREE:754166670:INVERSION_OFF:BANDWIDTH_8_MHZ:FEC_3_4:FEC_3_4:QAM_16:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:0:0:4351


scan results when THREE is transmitting

BBC 
THREE:754166670:INVERSION_OFF:BANDWIDTH_8_MHZ:FEC_3_4:FEC_3_4:QAM_16:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:620:621:4351

If you look carefully the video and audio pids are 0 when it is off the 
air. When did you run scan?

I would check your pids. I've been working with Daniel on a script that 
takes the output of scan and loads up the various tables. I could let 
you have a copy. (It's not complete yet).

Back to the original problem:

Ideally the backend should respond indicating no program data is available.
It should also cope with different apids and the vpid/apid not being 
present (e.g. no vpid = radio station)
