摘要： A standard reproduction model for ensuring real time reproducing on a disk-shaped information recording medium, includes a pickup (102) that reads the real time data from the information recording medium, a buffer memory (103) that temporarily stores the real time data read by the pickup, and a decoding module (104) that reads the real time data from the buffer memory (103) and processes the read real time data. An access time Tacc of the standard reproduction model is expressed by the following formula, Tacc=A·dN+Trev+B where dN is a difference in rotational speed of the disk-shaped information recording medium, Trev is a rotation waiting time at a target access position, A and B are constants.

摘要： To improve the convenience of a record medium and allow a record process and reproduction process to be more easily performed than before. When a clip edit list update process 121 that updates video data and audio data recorded on a disc 32 is executed, an index file management section 72 manages and updates an index file held in an index file hold section 51 as the video data and audio data are updated. At this point, a search section 92 searches disc internal IDs assigned to clips or edit lists contained in the index file for the maximum value. A disc internal ID generation section 91 generates a disc internal ID according to the maximum value. An index file management section 72 updates the index file with the disc internal ID generated by the disc internal ID generation section 91.

摘要： To allow the determination of whether data can be reproduced to be easily performed. When a plurality of clips generated by a photographing process are connected as an edit, an edit list management section 15 identifies encoding systems of a plurality of clips (video files) to be connected and writes the identified encoding systems to an edit list file that manages an edited result. An optical disc 30 on which a clip, an edit list file, and so forth have been recorded is loaded into another reproduction apparatus. When a command that causes an edited result recorded on the optical disc 30 to be reproduced is input to the other reproduction apparatus, the reproduction apparatus reads encoding systems written in the edit list file and determines whether the encoding systems are systems for which that the reproduction apparatus can decode data. In this manner, the reproduction apparatus determines whether it can reproduce the edited result. The present invention can be applied to an edit apparatus that edits for example pictures and so forth.

摘要： In order to perform simultaneous recording of a plurality of pieces of real time data, a large capacity of buffer memories were required. In addition, it was difficult to reproduce data which was recorded by a different apparatus. The present invention has an objective of providing an information recording medium, a simultaneous recording method, and an information recording and reproduction apparatus which guarantee simultaneous recording. The simultaneous recording is guaranteed by reproducing data in each of areas having at least a minimum size fulfilling the simultaneous recording condition which allows for the number of access operations which is twice the number of pieces of real time data to be recorded, and when the data amount in the buffer is empty, switching the current recording operation to another recording operation to continue recording.

摘要： A progressive scanned signal processing apparatus for inputting progressive scanned image signals and processing them as 420P signals comprises a signal processing means and a storing means in order to prevent the qualities of images of color difference signals from being lowered. A delay time required for carrying out a whole signal processing is expressed by 2×N×F (herein, N>0, N is an integer and F is time necessary for a period of one frame). Accordingly, the delay time necessary for the signal processing is expressed by the frames of even number, so that a main signal can be prevented from being replaced by a sub-signal.
