An Adaptive Broadcast System for the UK Digital TV Network

Adaptive TV broadcast is a way of further improving the energy efficiency of broadcast TV by adapting the broadcast powers and beam patterns based on user feedback. Here, a distributed monitoring network consisting of user TVs and professionally run calibrated nodes would feedback Quality of Service data to the broadcaster in order to build up a more accurate view of the coverage and field strengths. Based on this information, beamforming techniques can be used to adapt the broadcast powers to provide the most energy efficient solution.
