A technique for providing interactive television viewing. A programming signal is combined with a code signal to form a transmission signal, wherein different programming signals correspond to respective code signals. The technique includes broadcasting the transmission signal, receiving the broadcast transmission signal with a TV receiver at a viewer's location, and displaying the programming signal in the received transmission signal. At least one code signal is pre-stored at the viewer's location. Interactive program data is also pre-stored at the viewer's location, wherein different interactive program data correspond to respective ones of the pre-stored code signals. The technique further includes detecting the code signal in the received transmission signal, determining whether the detected code signal matches the pre-stored code signal and, if so, inputting to a display the pre-stored interactive program data that corresponds to the detected code signal, displaying to the viewer the interactive program data that corresponds to the detected code signal, and recording a viewer response signal that has been manually inputted, interactively with the displayed programming signal, based on the displayed interactive program data.
