The TV broadcast band has recently been reduced to make way for 4g mobile services. Further channels will be removed by 2018.
There is a school of thought that by the early 2020's the majority of TV reception will be either from satellite or over fast broadband, which will make maintenance of the elaborate terrestrial TV network uneconomic and subject to closure.
So it would be inadvisable to base any new service on it.
