April 1 was the switch off date for the last phase of digitisation, of the rural areas. The I and B ministry had instructed all multi-system operators (MSOs), local cable operators (LCOs) and broadcasters to ensure that analog signals are not transmitted after the deadline ends. Tamilnadu has resisted the switch off,with the state owned Tamil Nadu Arasu Cable TV Corporation saying that they cannot switch off analog signals since the implementation of DAS in Chennai and Tamil Nadu is pending before the Madras High Court.(Television Post)
