[linux-dvb] help on timing stuff

[giancarlo@baracchino.it]

Hi, I would like to know how I can determinate the exact istant when the TS 
packet (that matches the currently demux rules) is received in the buffer 
of the sat-dvb card or when it is sent to the driver.

I would like also to know if it is possible to get the current status of 
the STC.

My target is to determinate the exact receiving time istant in order to 
estimate the jitter on the packets. I know that a good correction of the 
jitter is obtained from  "max(PCR - STC)" but I would like to follow 
another "kernel" way (do_gettimeofday at every TSP receved with the same 
pid, and then subtract).

Any advices?
