1. A presentation system for receiving a plurality of series of digital data segments from a server source, each one of said series of digital data segments repetitively transmitted from said server source to said system on a cyclic basis, a respective digital data segment including a first data portion from which an image can be constructed and a second data portion including information related to said image and further including a priority value which defines a priority of said respective digital data segment in relation to priorities of other digital data segments in a series of digital data segments containing said respective digital data segment and said other digital data segment and, if required, information which links an active area on said image to another data source, said system comprising:

  • interface means for receiving said plurality of series of digital data segments;

    switch means coupled to said interface means for selecting at least one of said series of digital data segments;

    memory for storing plural digital data segments;

    display means for displaying an image constructed from a first data portion of a data segment included in said at least one of said series of digital data segments;

    processor means for examining a priority value of each received digital data segment and for storing in said memory those digital data segments which have a higher assigned priority value, to render those digital data segments more immediately available for user selection than digital data segments having lower assigned priority values, said processor means further responsive to a user selection of an active area of said image that is displayed by said display means to employ information from a second data portion associated with said image to operate said switch means to access said another data source, without communication with said server source.
