MPEG DATA RECORDING AND REPRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a recording and reproducing method for attaining seamless reproduction with high quality without causing contradiction of overflow and underflow on connection of a VBV buffer in the case of joining the first MPEG image data to the second MPEG image data and reproducing the resulting image data.

SOLUTION: Data of a joining interval A of the first MPEG image data are decoded and then re-encoded. The re-encoding is executed while being controlled so that transition of a VBV buffer occupied value may be started from a VBV buffer occupied value at a position (a) and finished up to a VBV buffer occupied value at a position (d). Then the first MPEG image data are reproduced until the position (a) of the first MPEG image data, and then re-encoded MPEG image data at the joining interval A are reproduced, and thereafter connection is made to the position (d) of the second MPEG image data and the second MPEG image data after the position (d) are reproduced.
