METHOD AND DEVICE FOR GENERATING INTERACTIVE-COMPONENT-DATA STREAM REPRESENTING APPLICATION-PROGRAM FOR AUDIO,VIDEO AND INTERACTIVE COMPOSITE-SIGNAL

摘要

PURPOSE: To prepare a data stream expressing an application program by selectively inserting a program file into a component stream in response to flow data at a flow builder. CONSTITUTION: An application programmer prepares source data while using a user input device 16 and a display device 15 and stores the source data in a temporary square storage device 17. A flow builder 10 processes the source data, relates a code file and a data file with a module, schedules the insertion of module into an application data stream and generates that data stream. Then, the output of flow builder 10 is supplied through an output terminal 19 to a transport packetizer 20. This transport packetizer 20 packetizes the interactive component data stream, this data stream and an audio component are engaged by a multiplexer 30 and AVI data are provided.
