Knowledge about A2 and NICAM 728 audio:
NICAM 728:
It is transmission of two-channel digital sound with terrestrial television systems B, G, H, l, K1 and L
A2 Stereo:
Known as "two-channel sound", it is an analog television sound transmission system used in Germany, Austria, Australia, Switzerland, Netherlands and some other countries that use or used PAL-B or PAL-G. .It relies on two separate FM carriers.
32 (or 16/48/64) standard PAL or NTSC or SECAM TV programs output via 32 (or 16/48/64)non-adjacent or adjacent carriers output within 400MHz
