just a stupid question:
How is a frontend supposed to handle that anyways?
The demods I know about only have one transport stream output,
how are high and low priority data separated?
(I was thinking it would have to be done by PID on a packet-by-packet
base, so it would transparent to the demux layer, but I did not find
an application really using hierarchical transmission yet.)
