Interactive services on tree‐and‐branch cable TV systems in the U.K. have been rather slow to emerge. This has been partly due to the high cost of the customers' terminals but is also due to the difficulty of passing keyboard data, from the customers, back over the cable network to the head‐end. This paper describes a new approach to these problems and shows that Videotex and other interactive services can be provided without major engineering changes to the network.
