DEVICE FOR PROCESSING MPEG-2 VIDEO/AUDIO TRANSPORT STREAMS AND METHOD THEREFOR AND SYNCHRONIZATION DATA SERVICE SYSTEM USING TRANSPORT DEVICE AND METHOD THEREOF

摘要

PURPOSE: A device for processing MPEG-2 video/audio transport streams is provided to supply an MPEG-2 video/audio transport stream storage/output device for storing and outputting video/audio contents coded in MPEG-2 transport streams, and to set reproduction time of synchronization data by using the storage/output device, thereby servicing the synchronization data. CONSTITUTION: A transport stream input portion(11) inputs MPEG-2 video/audio transport streams in real time, and transmits the transport streams to a transport stream output portion(14) or a transport stream storage(12). The transport stream storage(12) stores the transport streams in file type, or outputs the transport streams in real time. The transport stream output portion(14) inputs the transport streams in real time, selects one of the transport streams, and outputs the selected transport stream. A controller(13) inputs a user input or an outer command, and controls each unit(11,12,14) to store or output the transport streams.
