I only know about sync pulses Technology Connections did on the presence of Macrovision on commercial VHS releases, as this not only screws up the VCR's ability to record from a Macrovision protected tape, but it screws up the TV's ability to "lock on" to that sync pulse as well. I'm assuming its a similar principle for what transmitters are looking for, but that being said there was a video on YouTube where some programme falls off the air but continues in sound but the ITV company in question were aware of it.
