A reproducing apparatus calculates available dubbing speeds based on a transmission capacity of the reproducing apparatus. The reproducing apparatus selects a dubbing speed N among the available dubbing speeds, wherein N is 2, 4 or 8. The reproducing apparatus reproduces digital information including a plurality of fixed-length packets from a first recording medium at a bit rate corresponding to the dubbing speed N. The reproducing apparatus (a) determines the number of the fixed-length packets included in one transmission packet in accordance with the dubbing speed N, (b) generates transmission packets from the digital information reproduced from the first recording medium, wherein each of the transmission packets includes the determined number of fixed-length packets, and (c) transmits the transmission packets to an external recording device so that the external recording device can record the digital information to a second recording medium at a bit rate corresponding to the dubbing speed N.
