Summary:A data structure, method and apparatus providing efficient retrieval of data from a segmented information stream. The invention utilizes a segmented data stream having an initial directory payload portion and a following payload portion including one or more object tables. The directory includes table descriptors associated with each object table including various field indicative of parameters of the respective object table. One of the fields comprises a bit array having at least one bit corresponding to each of the segments in the respective object table. By changing a state of a corresponding bit upon receiving a table segment, the memory and processing resources required to read the segments associated with a table are decreased.
