A recording apparatus, a recording method, a recording medium, and an electronic camera which create an index file (IF) for holding index information of a file separately as a fixed data length portion and a variable data length portion and record the index file on the recording medium. The recording apparatus comprises creating means for creating the IF including a plurality of areas to each of which a unique identifier is assigned and recording means for recording the IF on the recording medium, wherein the creating means divides file attribute information into first attribute information of a fixed data length and second attribute information of a variable data length, holds separately a plurality pieces of first attribute information associated with a plurality of files, respectively, and a plurality pieces of second attribute information associated with the plurality of first attribute information, respectively, in the plurality of areas while the plurality pieces of first attribute information are associated with the plurality of files, respectively, and the plurality pieces of second attribute information are associated with the plurality pieces of first attribute information, respectively, and the creating means collects areas of the plurality of areas with a fixed data length as a first area group, and collects areas with a variable data length as a second area group, and holds them in the IF.
摘要:
A recording apparatus, a reproduction apparatus, and a file management method are disclosed wherein the operability in management of a large number of files recorded on a recording medium using an index file can be improved significantly further than ever. An index file is formed from a series of entries of extract information from a large number of files. Information indicative of a relationship between the files is set to the index file. The index file is used to manage a large number of files and so forth recorded on a recording medium.
摘要:
A recording apparatus, a reproduction apparatus and a file management method are disclosed wherein, even if one of files recorded on a recording medium cannot be reproduced regularly, another file selected by the user can be reproduced normally. A file having a hierarchical structure formed from video data and audio data both in the form of compressed data together with information necessary for processing of the video data and audio data is produced and recorded on a predetermined recording medium. Upon production of the file, information regarding decoding of the video data and audio data is disposed collectively on the top side of the file.

A reproduction apparatus reproduces view data including several tracks within a range of reproduction processing capacity. A reproduction apparatus for reproducing data from a recording medium having several tracks each used for recording image data and one or more pieces of edit data includes an input unit for inputting the data from the recording medium, an analysis unit for identifying the recording track type of the input data, a storage unit for storing a priority-level assignment table associating the track types with priority levels for a decoding process, and for storing a predetermined threshold value serving as a border between the priority levels for data to be reproduced and the priority levels for data not to be reproduced, a plurality of decode units each used for decoding a different type of data, and a priority-level determination unit for determining whether the input data is to be decoded based on the track type identified by the analysis unit, the priority level assigned to the input data and the threshold value, and for outputting the input data to one of the decode units selected in accordance with the type of the input data when decoding the input data.
摘要:
A recording apparatus for recording video data to a record medium is disclosed, that comprises an encoding means for encoding video data in a group structure of a plurality of frames corresponding to a compression-encoding process in a combination of an inter-frame predictive encoding process and a motion compensative process, a transforming means for transforming the data structure of encoded video data that is output from the encoding means into a file structure that can be processed by a computer software program without a dedicated hardware portion so that moving pictures and so forth are synchronously reproduced, and a recording means for recording data having the file structure to a record medium, wherein the file structure has a first data unit and a second data unit, the second data unit being a set of the first data units, and wherein at least one data structure is matched with the first data unit.

摘要:
The present invention relates to a recoding apparatus and a recording method, a playback apparatus and a playback method, a recording/playback apparatus and a recording/playback method, and a program, whereby processing relating to a file can be readily performed. With a video camera wherein with regard to H.264/AVC for example, which is a coding method arranged to encode or decode data, a codec class arranged to classify the performance of a codec configured to encode or decode data, and a codec level serving as a group of said one or more codec classes whose upper compatibility is ensured, are based on stipulated specifications, data is encoded into, for example, coded data of a codec class #2, for example, within a codec level AVC_A by H.264/AVC. The coded data is recorded in a recording medium, for example, as a file “AVCA0001.MP4” whose file name represents the codec level AVC_A of the coded data. The present invention can be applied to, for example, a video camera from which a recording medium can be detachable.
