A digital television broadcast system offers many improvements over analogue transmission; it allows the delivery of a greater number of TV channels into the home by the use of multiplexes. If the signal is successfully received and decoded, it can guarantee a set picture quality, as digital is more resilient to noise and interference than analogue. This can be exploited further by reducing the total broadcast power at the transmit towers, something that has already been achieved as part of the digital dividend. This paper explores whether the broadcast power could be decreased further, or if more users could be covered using the same broadcast power. If the entire broadcast system were made more adaptive, then beams could be steered to regions where coverage is needed. This adaption could come in the form of feedback from televisions supplied by a relay network that operates over the internet. This paper explores the possibilities and benefits of such a system.
