Abstract
An arrangement for enhancing the process of extracting data from a broadband video digital data stream. The data structure specified in the standards is enhanced by the addition of a symbol table which translates between a symbolic name of a program and the corresponding program number of the program and the channel on which the program is being broadcast. Advantageously, any program may be broadcast over any channel and a symbolic naming convention which can be designed to avoid conflicts among independent designer groups can be utilized. The programs referred to above are either the entertainment programs such as motion pictures or software programs for controlling a set top terminal.
