The time necessary for dubbing of a bit stream is reduced. A high speed dubbing apparatus includes: a read section ( 20 ) for reading a bit stream conforming to a DVD-VR standard from a first storage device ( 10 ), and outputting the bit stream; a first buffer ( 30 ) for storing an output from the read section ( 20 ) and outputting a bit stream; a navigation pack generator ( 40 ) for replacing a real time data information pack in the bit stream output from the first buffer ( 30 ) with a navigation pack, and outputting a resultant bit stream; a second buffer ( 50 ) for storing an output from the navigation pack generator ( 40 ) and outputting a bit stream; and a write section ( 60 ) for converting the bit stream output from the second buffer ( 50 ) into a bit stream conforming to a DVD-video standard, and writing the resultant bit stream in a second storage device ( 70 ). At least two of the read section ( 20 ), the navigation pack generator ( 40 ) and the write section ( 60 ) operate in parallel.
