The disclosure relates to a digital media file format comprising a number of sections for storing information, said sections comprising a first section with compiled reproducible media content, and a second section comprising one or more media elements. The disclosure further relates to a digital media file in the digital media file format, a computer-readable medium comprising the digital media file format, a method for creating a digital media file in the digital media file format, a method of obtaining a variant of a digital media file in the digital media file format, and a system for providing a digital media file in the digital media file format.

A cartridge is provided and includes tape-shaped magnetic recording medium; and cartridge memory; wherein cartridge memory includes communication unit that communicates with recording/reproducing device in state where cartridge is loaded on recording/reproducing device; storage unit; and control unit that stores, reads, and transmits information, wherein information includes manufacturing information of cartridge and adjustment information for adjusting a tension applied to the tape-shaped magnetic recording medium in a longitudinal direction of tape-shaped magnetic recording medium thereof, tape-shaped magnetic recording medium has a plurality of servo bands, and wherein a temperature expansion coefficient α of the tape-shaped magnetic recording medium satisfies 6 ppm/° C.≤α≤8 ppm/° C.

There is provided a recording apparatus, a recording method, a reproduction apparatus, a reproduction method, a recording medium, an encoding apparatus, and a decoding apparatus which enable recording or reproduction to be easily implemented at high line density. User data is encoded into a multilevel edge code, and a multilevel code whose value changes in accordance with the multilevel edge code is recorded. The multilevel edge code is generated through state transition of a code generation model which includes a state representing the number of times that zero is consecutive corresponding to a number of ways of the number of times that zero is consecutive, which is the number of times that an edge of 0 is consecutive among edges representing a change amount from an immediately preceding value of the multilevel code of an ML value which is equal to or greater than 3, and which transitions to a state representing the number of times that zero is consecutive including 0 in a case where 0 is output, and transitions to a state representing that the number of times that zero is consecutive is 0 times in a case where one of 1 to ML−1 is output.

A method for generating a multimedia file includes selecting a multimedia clip according to at least one received input instruction in a process of multimedia recording, parsing the selected multimedia clip to obtain corresponding text information, generating a multimedia file according to the at least one received input instruction, and generating a file name of the multimedia file according to the text information. Accordingly, the multimedia file is generated using text information that is obtained by parsing a multimedia clip, so that a file name of the multimedia file reflects information of the multimedia file.

A data storage device is disclosed comprising at least one head configured to access a magnetic tape. The head is used to write contiguously to the magnetic tape a first preamble, followed by a first sync mark, followed by symbols of a first data sector, followed by a second sync mark, followed by a second preamble, followed by a third sync mark, followed by symbols of a second data sector.

A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, a complete index that can be used to locate each data chunk in each of these tracks and an abridged index that can enable the location of a subset of the data chunks in each track, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and ‘meta data’ external to the file.

[Object] To quickly and correctly reproduce an image intended by a photographer, a cinematographer, and the like on the occasion of post-production. [Solving Means] The development apparatus includes: an imaging unit that performs shooting and generates RAW data; a first conversion unit that converts the generated RAW data into image data by interpolation; an acquisition unit that acquires an exposure index value corresponding to an illuminance of a shooting environment; a first correction unit that corrects a value of the image data based on the exposure index value; and an output unit that associates the RAW data and the acquired exposure index value with each other and outputs the associated RAW data and exposure index value.

A video scene is displayed in a either a tag mode or a tagless mode. The video scene depicts a plurality of visually perceptible items. The tag mode displays one or more visually perceptible tags in conjunction with the video scene. Each tag is associated with a visually perceptible item appearing in the video scene. The tags are categorized into a plurality of categories. In response to a request to display the video scene in the tag mode for a first one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the first one of the categories. In response to a request to display the video scene in the tag mode for a second one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the second one of the categories.

A cartridge is provided and includes tape-shaped magnetic recording medium; and cartridge memory; wherein cartridge memory includes communication unit that communicates with recording/reproducing device in state where cartridge is loaded on recording/reproducing device; storage unit; and control unit that stores, reads, and transmits information, wherein information includes manufacturing information of cartridge and adjustment information for adjusting a tension applied to the tape-shaped magnetic recording medium in a longitudinal direction of tape-shaped magnetic recording medium thereof, tape-shaped magnetic recording medium has a plurality of servo bands, and wherein a temperature expansion coefficient α of the tape-shaped magnetic recording medium satisfies 6 ppm/° C.≤α≤8 ppm/° C.
