Abstract

Disclosed is a two-stage television signal distribution system useful for distribution where the first stage of the television distribution occurs over satellite. The distribution system has a distribution control centre for producing a television signal including system control information in the vertical blanking interval thereof. The television signal is carried over a first transmission means to at least one receive station. Each receive station is provided with storage means for storing incoming television signals under control of the system control information contained in the television signal. The system further provides a second transmission means having multiple television channel capacity for transmitting television signals from each receive station to a plurality of terminations (i.e. the audience) where the television signals carried on said second transmission means include television signals previously stored at the receiving station and may also include the television signal carried on said first transmission means.
