When a digital TV system operates with excess transmit power there is no benefit for either the user or broadcaster. New research has found that by deploying a spatially adaptive broadcast system, broadcast powers can be reduced by up to 35 per cent, reducing carbon emissions and saving money.
A spatially adaptive broadcast system allows the broadcaster to adapt the geographical coverage from the transmitter based on what is actually happening in real-time to the radio frequency emissions. This is similar to what happens in a cellular network, which adapts to the needs and locations of subscribers.
