This is very good question. We should make a decision. If we use 50Hz, we
can easily calculate frames per second, otherwise we have to translate
sampling rate to physical rate.. But it's the only good point which I see.
Also, the situation is very easy for GSM where the sampling rate is fixed,
but what about some variable rate compressions with different sampling
rate / physical rate ratio?
