Abstract

A method and apparatus for reducing noise in pictures produced from satellite transmissions in which noise signals are identified and replaced by colour signals derived from adjacent portions of the picture signal corresponding to the position of the noise signal. Also described are: means for connecting a plurality of card readers to a satellite transmission decoder; a method of monitoring available TV channels and alerting the viewer to the commencement of pre-selected programmes and/or automatically selecting the channel on which a pre-selected programme is commencing; and means for connecting a satellite decoder and receiver arrangement to and automatically switching between a plurality of satellite dishes or receiving devices on a single dish.
