Abstract: Access point pictures designated as randomly accessible positions are I pictures or P pictures. Information indicating the decoding sequence (I1, P1, B1, B2, B3, B4, P2, . . . ) of pictures functioning as access points and attribute information (picture_type) indicating whether a picture functions as an access point or is necessary for decoding of the access point following a given access point are recorded on the video information recording medium. Random access is possible even if the GOP interval is lengthened.

Abstract: The present invention has an objective of providing an optical disk having a high resolution picture and a system for reproducing data on the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution picture. A high resolution signal is divided into a main signal and a sub signal by picture division means and MPEG-encoded. The main signal and the sub signal are divided into frames each having 1 GOP or more. The resultant first interleave block 54 and second interleave block 55 are recorded alternately on an optical disk. A high resolution reproduction apparatus reproduced both the first and second interleave blocks, so that a high resolution picture is obtained. A non-high resolution reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution picture.

Abstract: An output control (OPC) information is recorded on the magnetic tape 1 in conjunction with an MPEG stream. The OPC information is composed of two bits and is extracted from a reproduced signal by the output control circuit 9 and controls the digital interface (D. I/F) 7 and the switch circuit 11. In case a first bit of the OPC information is “0”, the output control circuit 9 makes the D. I/F 7 enabled and permits the output of a digital signal. In a case of “1”, the output control circuit 9 prohibits to output the digital signal. Further, when the second bit of the OPC information is “0”, the output control circuit 9 turns the switch circuit 11 off, preventing the output of an analog component signal. In case its “1”, the output control circuit 9 permits the output of the analog component signal.

Abstract: Video signals received on TV channels are recorded and reproduced with time-division compression and decompression to and from a storage medium to allow the video signals to be reproduced while the signals are being recorded. A channel-switching signal is generated when a first TV channel is switched to a second TV channel. Recording of a video signal received on the second TV channel is inhibited for a specific period until a normal video signal received on the second TV channel is gained after the output of the channel-switching signal. Recording of the video signal received on the second TV channel is allowed when the specific period elapses.

Abstract translation: 在TV频道上接收的视频信号通过对存储介质进行时分压缩和解压缩而被记录和再现，以允许在记录信号时再现视频信号。 当第一TV频道切换到第二TV频道时，产生频道切换信号。 在第二TV频道上接收的视频信号的记录被禁止一段特定的时段，直到在频道切换信号的输出之后获得在第二TV频道上接收的正常视频信号。 当经过特定时间段时，允许记录在第二TV频道上接收的视频信号。

Abstract: Upon playback of stream data which is recorded while being appended with time stamp information in units of packets, time management is made using the time stamp information. A video playback time viewed from the user, which may be indicated by I-, B-, and P-picture display times, is different from the time of the time stamp information. For this reason, when time management for the stream data recorded on an information storage medium is made using only the time stamp information, display time control (video playback time control) for the user cannot be accurately done. In this invention, a time relationship table indicating the relationship between the time stamp information recorded in stream data at each I-picture start time position and display time information (PTS or field information) for the user is provided to a portion of management information.

Abstract: A regular edition video of a video title is split into shots or scenes with time codes, and provided information, which is the semantic evaluation of the story, is added to the respective scenes to organize the scene score. Necessary scenes for each purpose are extracted on the basis of the scene score and a threshold value (process Pr14). Video characteristic evaluation information is added for each shot constituting each of the extracted scenes so as to organize the shot score (process Pr16). Optimum shots for each of the extracted scenes are selected on the basis of a predetermined rule suitable for the purpose (process Pr16). The optimum shots are sequentially cut out from the regular edition video (process Pr21), thus automatically organizing a preview video suitable for the purpose (process Pr22).

Abstract: By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal. The additional signal is then recorded in the free area instead of being inserted into the point of insertion. Since the free area is larger in size than the length of the additional signal, the rest of the free area is filled up with a portion of the existing signal adjacent to the point of insertion.

Abstract translation: 通过减少用于从记录介质播放信号的操作中的寻道操作次数，临时存储在信号记录/重放装置中使用的读缓冲存储器中的数据量足够大以作为重放信号被输出 搜索操作，允许执行连续播放操作。 为了减少搜索操作的数量，信号总是被记录在连续空闲区域中的记录介质上，每个区域的大小等于或大于通常设置为1分钟的预定记录/重放时间长度。 如果需要将具有小于预定记录/重放时间长度的长度的附加信号插入到已经被现有信号占据的区域中的插入点中，则具有等于或大于预定记录/重放时间长度的尺寸的连续空闲区域 记录/播放时间长度被新分配给附加信号。 然后将附加信号记录在空闲区域中，而不是插入插入点。 由于空闲区域的尺寸大于附加信号的长度，所以剩余的空闲区域被填充有与插入点相邻的现有信号的一部分。
