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.

A multiplexing and distribution system is provided for use in a digital data distribution system for multiplexing block data which represent predetermined quantities of information with stream data representative of a continuous flow of information onto a single distribution channel. The multiplexing system utilizes a framing technique in which fixed time intervals, or frames, are provided along the distribution channel. The start of each frame is defined by one or more digital bytes which represent frame synchronization characters. A stream control character is inserted in each frame after the frame synchronization characters. Consecutive stream control characters may be concatenated to provide a control channel which contains information used to select which particular stream data channels are to be multiplexed, and where the data is to be placed within the frame. A multiplexer controller selects the particular stream data channels which are to be multiplexed, and inserts successive one byte increments of each of these stream data channels into each successive frame after the stream control character. The remaining space in each frame is filled with consecutive block data.
