A presentation player is described for use in an interactive digital communications system which may selectively communicate particular multimedia presentations to each of a plurality of subscribers along a CATV cable network, or other communications network. The player is part of a digital interactive system that distributes information representing requested presentations in the form of digital data on distribution channels to a plurality of presentation players located along the communications network. Each of the subscribers has a television set connected to one of these presentation players. The digital data is uniquely addressed to a particular subscriber and is processed by his corresponding presentation player to produce analog TV signals comprising the multimedia presentation. The presentation player automatically tunes itself to a distribution channel and can process data which include motion video sequences, background music, and real-time live video images, in addition to still-video images with audio commentary. The presentation player of the present invention comprises a converter capable of receiving the distribution channel frequencies and selecting one of those frequencies for further processing of digital data transmitted thereon.
