Apparatus and a method for formatting executable codes and data, defining interactive applications, with video and audio program material, for reliable and convenient access includes compressing (18, 21) audio and video programs according to a protocol such as MPEG. The compressed audio and video (A/V) programs are formed (19, 22) into transport packets. Interactive application programs associated with A/V programs are compiled (10) into functional modules, condensed and formed into transport packets. A module may be executable software or data. Further modules designated "Signal modules", are generated to condition respective receivers to suspend or resume execution of an interactive application. Video packets, audio packets and application packets are time division multiplexed (16) for transmission. Signal modules are multiplexed in the packet stream to appropriately reprogram respective receivers on the occurrence of such changes in received signal components.
