Abstract:
1. A high speed dubbing apparatus, comprising: a read section for reading a bit stream conforming to a DVD-VR standard from a first storage device, analyzing the readout bit stream and outputting obtained stream analysis information and the readout bit stream; a first buffer for storing an output from the read section and outputting the stored bit stream, the first buffer having a capacity equal to or larger than the size of a VOBU (Video Object Unit) of the readout bit stream; a navigation pack generator for replacing a real-time data information pack in the bit stream output from the first buffer with a navigation pack using the stream analysis information, and outputting a resultant bit stream; a second buffer for storing an output from the navigation pack generator and outputting the stored bit stream, the second buffer having a capacity equal to or larger than the size of the VOBU of the readout bit stream; and a write section for converting the bit stream output from the second buffer into a bit stream conforming to a DVD-video standard using the stream analysis information, and writing the converted bit stream in a second storage device, wherein a first sum is less than both a second sum and a third sum, the first sum is a sum of: the second sum is a sum of: the third sum is a sum of: wherein the read section, the navigation pack generator, and the write section operate in parallel.
