摘要:
A data processor transfers a data stream, which is stored on a storage medium, to a connected device. The data stream includes attribute information that specifies the format of the data stream. The data processor includes: an interface section, which communicates with the device to acquire format information about a format that is compatible with the device; a reading section for reading the attribute information and the data stream from the storage medium; a reading control section for determining, by the attribute information and the format information, whether or not the format of the data stream needs to be converted; and a converting section for outputting the data stream either after having converted the format of the data stream into the one specified by the format information or without converting the format of the data stream as determined by the reading control section. The interface section transmits the data stream, which has been output from the converting section, to the device.

A data processor includes: a first receiving section for receiving a first signal to acquire a first data file including a first data and a first piece of related information showing contents thereof; a second receiving section for receiving a second signal; a data generating section for generating a second data based on the second signal; a processing section for generating link information showing a location of the first piece of related information, in response to the first signal and for generating a second piece of related information, showing contents thereof, in response to the second signal; a decision section for generating a different piece of decision information according to a type of the signal received; a management file generating section for generating a management file, including the decision information and the link information, for the first data; and a writing section for writing the management file and either the first data file or a second data file on the storage medium. The second data file includes the second piece of related information and the second data.
摘要:
In a disk camera, when additional information and moving picture information are managed as one file and recorded on an optical disk, useless area is minimized, thereby allowing effective use of recording capacity. A recording controlling part records continuously with respect to a logical block of the optical disk, at least one of input video and audio information in a packet format of a fixed length that is different from a data size of the logical block, and creates a data file for recording with respect to the logical block, additional information with respect to the video or audio information in the packet format of the fixed length. In this one data file, a fixed data size portion of the additional information is arranged in an area ahead of an area in which the video and audio information are arranged, and a variable data size portion of the additional information is arranged in an area behind the area in which the video and audio information are arranged.
摘要:
A file management method for reducing a seek operation to a minimum even when a UDF file system is used is provided. The file management method has file management information for managing contiguous blocks on a disc as an extent and for grouping the extent as a file and managing the file, and includes the steps of: when creating a new directory on the disc, reserving as a reserved area for recording file management information on the file a file or a data area in the directory; and reserving a directory block having a predetermined size in the reserved area for recording a file entry of the directory and a file identifier descriptor of the directory.
摘要:
The present invention provides an AV data recording apparatus and method that facilitate various processes concerning a recorded video, including continuous reproduction, digital transmission, file operation, partial deletion, and post-recording. The AV data recording apparatus divides an audio signal and a video signal into transport packets having a predetermined unit length, assembles a plurality of transport packets as one transport stream and executes recording. Accordingly, this invention enables managing whether a logical block is used or not, detecting a continuous data area comprising plural logical blocks that ensure realtime continuous reproduction, and determining logical block numbers of continuous data areas to be recorded. As a result, the transport stream is recorded continuously on a plurality of detected continuous data areas.

摘要:
A moving image data management apparatus which manages moving image data and representative image data by using one or plural representative image data in correspondence with each moving image data. A thumbnail representing an arbitrary section in a moving image represented by moving image data is generated, and stored in a thumbnail area of the moving image file. Indexes corresponding to the respective thumbnails are stored in an index area of the moving image file. Each index includes start point/end point indicating a section in moving image data represented by the thumbnail image and attribute information indicating usage of the thumbnail. By this attribute information, operability of moving image data using representative images can be improved upon execution of various moving image data processing, and management of the representative images can be simplified.
