Abstract: A data broadcast receiving apparatus used in a system is combined with another transmission line such as telephone circuit. By receiving a television broadcast having a data broadcast signal, such as a teletext signal, superposed on the television broadcast signal, in which a first auxiliary information signal contained in the data broadcast signal and a second auxiliary information signal from the other transmission line are extracted, a control procedure is created responsive to the first and second auxiliary information signals, and the data broadcast signal and main information from the other transmission line are processed responsive to the control procedure.
