How to get DVB-T's bitrate in realtime.

[silenceboy]

Just making DVB-T application with Philips card.
After building DVB-T graph, before running, I need to know its bitrate.
Because I need this info to do PVR control.

My questions:

Is it possible to get this bitrate?
If could, How can I get this bitrate in DShow Filters?
Should I tune some channel first to make bitrate available?
Is this bitrate CBR or VBR?
Does different channel have different bitrate?

I googled, but cannot find any relative info.

You must know transport parameters ie: FFT size, FEC, modulation type/constelation, bandwith, Guard Interval. For DVB-T all allowable bitrates are listed in the EN 300 744.

TSreader can give the bitrate of a PID in realtime.
Or there is a software from Tektronix which can do it.
I use TSReader to record and see some information (in realtime)
of french DVB-T channel in H264 HD (TF1HD, M6HD and Canla+ HD)
