My blief is that the solution needs to support frame sizes ranging from 
5ms up to somewhere around 100-250ms. It might be that internally it's 
actually only doing 5-20 ms and it's the transport that package it 
together so that the fps is way down, but I think it still needs to be 
taken into account when design is done.
