Many audio tracks as different channels
On HotBird 13E, on tp. 15 (11,488 GHz, pol. H, SR: 27500, FEC: 3/4; DVB-S2/8PSK) there is the following radio channel:
ID: NC+ RADIO
PID PCR: 420
PID PMT: 1046
It contains many audio tracks and every track is another, different radio.
How can we distinguish them? Can we map every audio track as a stand-alone radio channel?
