For a laboratory model of an interactive CATV system services are presented and classified. The problem of predicting usage parameter for non-existing services in a non-existing network is discussed. An approach to gain a first preliminary set of data describing the distribution of demands and requirements of the various services is presented. It starts from the contents offered by means of a service and from the way these contents are offered at present and tries to estimate the extent to which they might be taken over into a CATV system. The approach is described in more detail by an exemplary service offering educational programmes.
