Okay. By that reasoning, because HD Radio sits "next to" the AM
signal, then it is not IBOC either. It is a simulcast format.
Do you agree with that statement?


As a whole? No.


- There is no technical difference.
- Both HD radio and DRM operate on the same principles:
- 2 separate signals
- 1 analog
- 1 digital
- the digital is simulcast "next to" the original analog signal


iBquity's IBOC Broadcast System is 'Intrinsic'
DRM's Simulcast Broadcast Scheme is NOT 'Intrinsic'


- That distinction is more about FAITH, than reality.

- There's no real difference between DRM's version
- (sitting next-to the AM signal) and HD's version
- (also sitting next-to the AM signal).


- SFTV,
-
- BLATANTLY TECNICALLY WRONG !
- ARE YOU SURE YOU ARE AN "EE" ?
