Abstract
Abstract A method is disclosed for processing an input signal related to streamed digital video data. The method is directed to an interactive media network employing a client-server architecture. The method begins with initializing a counter. The counter may represent an elapsed time or a frame number. Next, the client station receives streamed digital video data representing multimedia information. The counter is then updated and the multimedia information represented by the streamed digital video data is displayed. Next, the input signal representing a user request is received at the user station. An index based on the value of the counter is then determined, and the method concludes by transferring execution control based on the index. A system is also disclosed for processing the steps of the above-described method.
