Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To resolve such a problem that special reproduction is not realized only by data which is encoded by inter-frame prediction since a special reproducing method or picture quality are greatly different in between two cases, i.e., when data to be sued as special reproduction data is encoded without using inter-frame prediction and when the data is encoded by inter-frame prediction. SOLUTION: Data obtained by encoding compression animation data without using inter-frame prediction and data encoded by inter-frame prediction are recorded as a special reproduction digital signal together. One of data encoded without using inter-frame prediction for the case of speed change reproduction and data encoded by inter-frame prediction is selected. Then it is recorded by multiplexing with normal data so as to be recorded at a fixed position in a direction along a recording rack on a recording medium.
