An editing apparatus for video data creates a bridge file for connecting a first file and a second file to be edited based on designation of an IN point of the first file, an OUT point of the second file, and connection points of the both files, a frame preceding the connection point of the first file being made an OUT point and a frame following the connection point of the second file being made an IN point, and the bridge file connecting the OUT point and the IN point, records the bridge file into a recording medium recording the first and second files, and creates an editing result file having file system information indicating recording positions: from the IN point to the OUT point in the first file; from the IN point to the OUT point in the second file; and of the bridge file, in the recording medium.

Editing apparatus and editing method

Disclosed is a recording apparatus for recording data on a recording medium. The recording apparatus includes an assigning section for assigning a region that is part of a block utilized for a recording unit of the recording medium as a file system information region utilized as a region for file system information for managing the data on the recording medium. The recording apparatus further includes a recording section operable to record file system information for data that has been recorded in all blocks in the file system information region of each block until the file system information region in a block is filled and to record file system information for data in all blocks subsequent to the block having the filled file system information region in the file system information region of each subsequent block after the file system information region in a block has been filled.

Recording apparatus and recording method for data and file system information

The present invention relates to an I/O device capable of collectively managing and easily editing AV data recorded by a plurality of video cameras with transfer bit rate between devices kept constant, and an I/O management system. The I/O management system according to the present invention comprises: a storage device having a non-linear accessible recording medium; a control unit for controlling output of externally supplied data with respect to the storage device, or input of data from the storage device; and one or more I/O device having a record information management unit for managing, through a file system, record information acquired at the time when data is recorded onto the recording medium, and controls input of data from the storage device on the basis of the record information managed by a file system at the time of reproduction.

Input/output device and input/output management system

An information management system has an information management apparatus that receives a data stream with a general-purpose format, which is constituted of data and additional information, from a data-supplying system and separates the additional information from the data stream to hold and manage the data obtained by separating the additional information from the data stream. The information management system has a data storage device that stores the data obtained by separating the additional information from the data stream with the information management apparatus. The data is stored in the data storage device as it is with the data having the general-purpose format.

Information management system, information management apparatus and information management method

A playback apparatus plays back data from a recording medium having recorded thereon a file system representing association between identification information for identifying a file and a position where the file is recorded, pieces of segment data constituting the file, and markers for the respective pieces of segment data, each marker that is recorded after a key marker specified in certain cases including location information of the key marker. The playback apparatus includes a detector that detects a last marker in a recording area where data has been recorded on the recording medium but has not been reflected on the file system, and a restoration processor that executes a restoration process of reflecting on the file system segment data that has been recorded on the recording medium but has not been reflected on the file system, based on the location information of the key marker and the location information of segment data.
