This paper illustrates the frequency synthesis technique which can be used for the very low power TV transmission. The idea behind the frequency synthesis is to use the low power TV transmission method usually 50 W using an integrated voltage controlled oscillator. Such transmitters can be established solely for community education and managed by existing schools as additional support for children and support for adult education in the rural India. The availability of the channel for the signal transmission is to be controlled using the white space detection techniques like cognitive radio, etc. Currently 85% of the TV band in the 470-698 MHz range is not used in the heart of urban Delhi, and as much as 95% are unused in rural areas. At any point in time, the largest contiguous TV white space varies between 66 MHz to 136 MHz in an urban location, and between 51 MHz and 242 MHz in a rural location. This shift of channel was achieved using IR remote controlled microcontroller based control system.[1][2].
