That's not the only type of compression in existence. Theoretically if
I want to transmit 3 streams of data which contain the same data most
of the time, then why not only transmit the differences? In this case
only transmitting the regional difference would save bandwidth as you
wouldn't need a whole 24 time slot for each Regionally stream. They
would only be broadcasting at the times that something differ. Thus
saving bandwidth. (provided you can broadcast something else in the
slot that regionally channels aren't utilising).
