The invention provides a television system for receiving data broadcast to a number of broadcast data receivers at different locations. The broadcast data receivers generate video and audio from the received data to represent television programmes selectable by a user. The invention provides for the transmission of portions of data in addition to the data for the programmes available at that instant. The portions of data allow the generation of video and/or audio "trailers" which represent a programme or service available for user selection and viewing in the future. The user can select the programme or service via the broadcast data received at the time of display of the video or audio trailer generated from the portion of data.
