With the closure of 405 line transmission for television pictures Bunny Carr explains the differences between 405 and 625 line transmission by using a photograph of a scene from 'Wanderly Wagon'. He also explains why the switch over is taking place and how television aerials receive the signals. A map of Ireland shows the main broadcasting transmitters.
This programme seems to have been a pilot for a planned series of public information pieces on changes being made in how RTÉ transmitted television pictures and what this meant for viewers.
The programme was recorded 20 June 1976 but does not appear to have been broadcast.
