    摘要： In an image data processing method of recording auxiliary data intended for splicing with the MPEG-2 technique to a recording medium, a VBV delay of an I or P picture is acquired from an data group led by the I or P picture and including a B picture, a VBV delay (VBV_delay_N) of a next picture is pre-acquired, the acquired VBV delay is recorded to an auxiliary recording area provided for each data group in order to record encoded image data to a predetermined recording area in a recording medium for each data group, and the pre-acquired VBV_delay_N is recorded to an auxiliary recording area for a next picture, provided correspondingly to a recording area for the next picture.

    摘要： Audio signals and video signals are recorded as follows. Three video PES packets, each being formed of one video frame, are combined to form a video editing unit. Then, the video editing unit and the associated audio editing unit are alternately disposed on a magnetic tape. The recorded PES packets are output as a TS as follows. A STC is initialized, and then, PSI packets of a PAT and a PMT are output. TS packets specially used for a PCR for storing the STC are then output at certain intervals. Subsequently, video PES packets are converted into TSs, and the output of the video TSs is started while synchronizing a time obtained by subtracting vbv_delay from the first I-picture DTS with the STC. Audio PES packets are converted into TSs, and the output of the audio TSs is started while synchronizing a time obtained by subtracting the start up delay from the first frame with the STC. Data streams are recorded in the following manner. The three MSBs of a sync block (SB) header indicate the type of data to be recorded in the following data area. If the data type is PES-VIDEO or PES-AUDIO, a full/partial flag is recorded in the fourth MSB of the SB header. In the subsequent four LSBs, the continuity count value representing the continuity of the same type of SBs is recorded.
