In earlier DVB-T or DTT analogue transmission, only one channel (Doordarshan National) can be transmitted through a transponder whereas in case of digital transmission (DVB-T2), multiple channels can be transmitted.
This digitisation could also open the possibility of new channels catering exclusively to cities same as FM channels with local programs, advertisements, weather reports and other public related information. ![Prasar Bharati Stopped Analogue Signals and Digital Transmission Started Prasar Bharati Stopped Analogue Signals and Digital Transmission Started]()
