I'm aware of that with regard to FM stereo, but with the acronym salad that has become television audio (MTS, DBX, SAP, NICAM, etc) i have no idea what's what, or how it's encoded. Somehow, he's ending up with SAP whenever it's available, and it's unclear to me how an analog decoder would select it. - Eric
