Two Audios (video description narrator for blind)
Posted: Thu Jan 12, 2017 12:29 pm
Hi,
DVB-T broadcasts two audio channels on two PIDs at the same time. While one PID plays regular audio (e.g. 273), another one (e.g. 275) contains only narrator's voice describing the video at the same language - it is a service "opposite to closed captions".
While I can switch between the channels by clicking on a loudspeaker icon in a left bottom corner, I need to play both channels at the same time.
Any way to do it?
Thx
