Data stream output apparatus

摘要

In a data stream output apparatus, it is so arranged that a read buffer(pre-reading buffer 103) is provided for storing the data stream read from the storage medium, and a memory is provided for storing a time table Mt indicating the position and size (Sm) of the data block to be sent out to the external device every given period (f) in the data stream, the data block including motion picture data to be decoded by the external device every given period (f). Further a send buffer 110 is provided for storing the data stream to be sent out to the external device via the digital interface. According to the arrangement of the data stream output apparatus, a controller is provided for controlling the outputting of the data stream stored by the read buffer 103 from the send buffer 110 to the external device via digital interface, so as to have a fixed size (K) when the size (Sm) of transmit data block is not equal to the fixed size (K), controls the outputting of the resultant data block from the send buffer 110 to the external device via the digital interface.
