摘要： In a picture data reproducing method of reproducing picture data recorded to a recording medium according the MPEG standard, there is provisionally stored, into a stream buffer, picture data grouped as a GOP which begins with an I picture, the picture data provisionally stored in the stream buffer is read sequentially starting with a previous picture and the read picture data is decoded in the course of a FORWARD reproduction being done, and picture data acquired from the recording medium is additionally supplied to the stream buffer. When the picture data provisionally stored in the stream buffer have been read in the decoding step to before last N frames, a predetermined amount of picture data is additionally supplied, in the data adding step, beginning at the head of a GOP including picture data in the remaining N-th frame in the stream buffer. Thus, a smooth variable-speed reproduction can be done according to the MPEG Standard.

摘要： In an STC generating step, STCs (STC_d) delayed a time “System_delay” from STC (STC_medium) in compressed picture data read from a recording medium in the normal-speed reproduction mode is sequentially generated. In this STC generating step, there is set at shift from a variable-speed reproduction to normal-speed reproduction an STC initial value on the basis of results of comparison between PTS (PTS_s) in display picture data at the time of reproduction mode shift and {STC_medium at the shift−(delay due to the shift (shift_delay)+System_delay)}. Thus, when shifting the reproduction mode from a variable-speed one to normal-sped one in compliance with the MPEG standard, pictures can smoothly be displayed in the normal-speed reproduction mode without skipping over any displayed pictures.
摘要翻译：在STC生成步骤中，STC（STC_d）在从正常速度再现模式中从记录介质读取的压缩图像数据中顺序生成STC（STC_medium）时间“System_delay”。在该STC生成步骤中，基于再现模式移位时的显示图像数据中的PTS（PTS_s）与再现模式移位时的比较结果与 {STC_medium at shift-（由于shift（shift_delay延迟）+ System_delay）}。因此，当根据MPEG标准将再现模式从可变速度转换为正常速度时，图像可以平滑地以正常速度再现模式显示，而不跳过任何显示的图像。

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.

摘要： 139 sync blocks, each having 111 bytes, are disposed on each track of a magnetic tape. Among the 139 sync blocks, 121 sync blocks each consist of a two-byte detection pattern for detecting the sync block, three-byte identification information for identifying the sync block, 96-byte main data, and 10-byte inner error correcting code added to the identification information and the main data. In the remaining 18 sync blocks, instead of the main data, 96-byte outer error correcting code is included. The outer error correcting code is provided for each group of the 139 sync blocks. Such a group of 139 sync blocks is obtained by dividing 2224 sync blocks contained in sixteen tracks by sixteen planes, 1668 sync blocks contained in twelve tracks by twelve planes, or 1112 sync blocks contained in eight tracks by eight planes. The sync blocks are arranged on the magnetic tape so that the distance between the sync blocks belonging to the identical plane is constant among the planes.

摘要： The present invention provides an image data processing method of recording image data coded with the MPEG (Moving Picture Experts Group) technique to a recording medium. For transition of the bit occupancy in a VBV buffer to a target value, the initial value of a bit occupany in a VBV buffer is calculated on the basis of auxiliary data read from a recording medium, a comparison is made between the target and intial values of the bit occupany, and the number of bits for assignment to each GOP of to-be-coded image data correspondingly to the result of comparison.
