The nature of the ATSC standard makes it possible to implement new functions in
the system using the same transmission and reception infrastructure. One of the greatest
advantages introduced in digital television is, in fact, the integration of processing in the
receiving device itself. Historically, in the design of any radio or television broadcasting
system, the objective was always the concentration of technical sophistication (when
necessary) in the transmission device, the receivers being simple and of low cost. Due
to the fact that there are more receivers than transmitters, this approach has certain
commercial advantages.
