For audio video interactive composite signal, representing an application program, a method for generating an interactive component data stream unit

摘要

A method and apparatus for generating an interactive component data stream, representing an application program, for an audio video interactive (AVI) composite signal, is disclosed. The method comprises the following steps. First, program files representing the application program are generated. Then, flow data defining the data structure of the interactive component is generated. Finally the data stream is generated by selectively inserting program files into the data stream in response to the flow data. Apparatus for generating such an interactive component data stream comprises a source of program files represent the application program and a source of flow data defining the data structure of the interactive component. A flow builder (10) selectively inserts (30) files from the source of files into the interactive component in response to data from the flow data source. MATH
