Abstract: Disclosed is a video signal recording system, in which the input video signal is rid of unneeded portions, transformed on the time axis and divided into n channels so that they are recorded in a bandwidth narrower than 1/n of original one. The system also enhances the latitude in choosing a clock frequency for time-axis conversion and a track width, thereby optimizing the picture quality and recording time length on a trade-off basis.

Abstract: 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.

Abstract: A data generation section generates an essence data file composed of a file header, a file body, and a file footer. A header size obtainment section obtains header size information of essence data file from the data generation section, and supplies the header size information to a clip generation section and an index file update section. The clip generation section generates a clip information file that describes the header size information supplied from the header size obtainment section. The index file update section registers a clip element that describes the header size information supplied from the header size obtainment section to an index file stored in a ROM.

Abstract: The present invention provides a recording/reproduction device that can perform post-record editing on a disk on which post-record editing has been determined to be impossible by conventional methods, and that can reproduce data that thus has been subjected to post-record editing, by devising a method for access in one cycle of repetitive processes of post-record editing. The recording/reproduction device is provided with a pick-up for recording or reproducing information and a control portion for controlling an operation of the pick-up, in which when reproduction is performed from an information recording medium on which in a separate area from a main sequence in which data blocks including original audio data and video data are recorded in succession, an additional sequence in which data blocks including post-record audio data are recorded in succession is formed, the control portion controls an operation of the pick-up in such a manner that the pick-up accesses the main sequence and the additional sequence alternately, and reproduces a plurality of data blocks in succession in each access.

Abstract: When a packet data is transmitted, a sync pattern comprising ‘q’ words (‘q’=m+n) is added to the data. The ‘q’ words is formed by combining a fixed pattern comprising ‘m’ words (‘m’ is an integer greater than 0) with plural types of variable patterns each comprising ‘n’ words (‘n’ is an integer greater than 1). In this case, a bit structure included in at least two consecutive packets should include different types of variable patterns.

Abstract: To improve the convenience of a record medium and allow a reproduction process to be more easily performed than before. When a reproduction process 123 that reproduces material data recorded on a disc 32 is executed, a disc information file management section 63 references a reproduction history of a disc information file held in a disc information file hold section 52 and starts reproducing material data from a position according to the reproduction history. When the reproduction process is completed, the disc information file management section 63 updates the reproduction history of the disc information file held in the disc information file hold section 52. A disc information file record control section 82 records the updated disc information file on the disc 32.

Abstract: In order to perform simultaneous recording and reproduction, a large capacity of buffer memories were required. In addition, it was difficult to record data while reproducing data which was recorded by a different apparatus. The present invention has an objective of providing an information recording medium, a simultaneous recording and reproduction method, and an information recording and reproduction apparatus which guarantee simultaneous recording and reproduction. The simultaneous recording and reproduction is guaranteed by reproducing data recorded in an area having at least a minimum size fulfilling the simultaneous recording and reproduction condition which allows for four access operations, recording data in an area having at least the same size, and performing reproduction and recording alternately by switching reproduction to recording when the data amount in the reproduction buffer becomes full and switching recording to reproduction when the data amount in the recording buffer becomes empty.

Abstract: 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.
