ABSTRACT:
Multiple data stream searching is achieved by encoding a video broadcast into multiple types of data streams including video, audio and subtitle data. Addresses are generated for each of the data streams pointing to a position of the data stream to be stored on a record medium. These addresses are stored in areas of the record medium reserved by type of data stream such that location of any event represented by data in a data stream can be achieved by locating the data streams of the same type as that of the data to be located. A computer-readable memory directs a computer to store these addresses and to decode data streams at these addresses which correspond to the type of data stream to be searched. The data streams which are of the type to be searched are decoded and the event to be searched is found in these decoded data streams.
