Signal transfer apparatus and signal transfer method

A signal transfer method comprising:

• a first block of separating an information stream and time information including its transfer start time from an input signal, and creating descriptors with respective identifiers for the information stream and time information;
• a second block of storing the information stream, time information, and descriptors obtained in the first block;
• a third block of reading a descriptor from the storage unit via a bus, and in the case where the read descriptor has an identifier that indicates an information stream, reading the information stream from the storage unit via the bus and transferring the read information stream to a predetermined transfer subject;
• and
• a fourth block of reading a descriptor from the storage unit via a bus, and in the case where the read descriptor has an identifier that indicates time information, interrupting transfer of the information stream by the third block, reading time information from the storage unit via the bus, and controlling transfer of the information stream by the third block on the basis of the read time information.

A reproducing apparatus comprising:

• a reader unit configured to read signals recorded in an information recording medium from the information recording medium;
• a processing unit configured to separate an information stream and time information including its transfer start time from the signals read by the reader unit and create descriptors with respective identifiers for the information stream and time information;
• a storage unit configured to store the information stream, time information, and descriptors obtained in the processing unit;
• a transfer unit configured to read a descriptor from the storage unit via a bus, and in the case where the read descriptor has an identifier that indicates the information stream, read the information stream from the storage unit via the bus, and transfer the read information stream to a predetermined transfer subject;
• and
• a transfer control unit configured to read a descriptor from the storage unit via a bus, and in the case where the read descriptor has an identifier that indicates time information, interrupt transfer of the information stream by the transfer unit, and also to read time information from the storage unit via the bus, and control transfer of the information stream by the transfer unit on the basis of the read time information.
