To provide a user with the capability of accessing audio/video material, and to remotely select, store and play back the material at any time, there is provided a receiving system responsive to a user input identifying a choice of an item stored in a source material library to be played back to the subscriber at a location remote from the source material library, the item containing information to be sent from a transmitter to the receiving system. The receiving system comprises transceiver means for automatically receiving the requested information from the transmitter as compressed formatted data blocks; receiver format conversion means coupled to the transceiver means; storage means coupled to the receiver format conversion means; decompressing means coupled to the receiver format conversion means; and output data conversion means coupled to the decompressing means for playing back the decompressed information in real time at a time specified by the user.
