Electronic program guide including live network multimedia broadcast channels

A system and method for generating an electronic program guide wherein a first information handling system obtains program information from a program information source and generates a program guide based upon the obtained program information. The first information handling system searches a worldwide network for information regarding a transitory broadcast event (such as a REAL VIDEO (RTM) event) and incorporates the transitory event information into the generated program guide prior to transmitting the program guide to the second information handling system. The transitory broadcast event information may be added to the program guide as additional, temporary channels that include links to the nodes from which the transitory broadcast event may be obtained. The program guide is thereby augmented with the additional, transitory broadcast event information. A second information handling system receives the program guide from the first information handling system.
