摘要： A video data recording apparatus detects a change in an attribute of a signal input with video data, generates management information showing a position in which the change was detected, and records the management information to a recording medium. The video data playback apparatus reads and plays back the video data up to the position shown in the management information recorded on the recording medium.

摘要： An optical disc recording apparatus for recording a video object onto an optical disc. A recording area of the optical disc is divided into a plurality of zones which each include a plurality of adjacent tracks. The optical disc recording apparatus includes: a reading unit for reading from the optical disc the sector information showing data assignment for sectors on the optical disc; a recording unit for recording the video object onto the optical disc; and a control unit for controlling the reading unit and the recording unit. The control unit detects at least one series of consecutive unassigned sectors on the optical disc by referring to the read sector information. Each series has a total size greater than a minimum size and is located within a single zone. The minimum size corresponds to a data amount that ensures uninterrupted reproduction of the video object. The control unit also controls the recording unit to record the video object into the detected series.

摘要： A VOB composed of a plurality of VOBUs and Cell information are recorded on an optical disk. Each VOBU includes a plurality of sets of picture data, and the Cell information specifies a reproduction section (Cell). According to a user indication, picture data corresponding to an IN point of a delete section and picture data corresponding to an OUT point of the delete section are specified in the Cell. If the number (j−i−1) of VOBUs present between the ith VOBU including the former picture data and the jth VOBU including the latter picture data is smaller than a predetermined number u, a warning of a data size increase is displayed. If j−i−1 is greater than u, the Cell information is rewritten so that the parts of the Cell preceding and succeeding the delete section become two consecutive Cells, and the (i+s+1)th to (j−t−1)th VOBUs are deleted from the optical disk.

摘要： A reproduction route composed of a still image section and a motion image section is recorded on a recordable DVD. A drive device (93) reads picture data from the DVD-RAM. An MPEG decoder (95) decodes and displays the read picture data. By referring to cell information, the judgment is performed as to whether the read picture data belongs to the still image section or the motion image data. If the read picture data belongs to the still image section, the next picture data is read out after a predetermined wait time.

摘要： An optical disc including: a data area storing one or more video objects; and a time map area storing time map information. Each video object includes a plurality of video object units. The time map information includes a first time table and a second time table for each video object. Each first time table includes: addresses of video object units in a corresponding video object; and indicators. The addresses are arranged in order and indicate storage positions of the video object units that correspond to reproduction points that differ by a predetermined time unit. The predetermined time unit is longer than a maximum reproduction period of a video object unit. The indicators specify the video object units which respectively correspond to the addresses. Each second time table includes an entry for each video object unit in the corresponding video object. The entries are arranged in order. Each second time table includes a reproduction period and a data size of each video object unit.
