Embodiment Construction

[0055] Hereinafter, the present invention will be described in detail by explaining exemplary embodiments of the invention with reference to the accompanying drawings.

[0056] Referring to FIG. 4 , an MPV document 400 , that is, an MPV manifest file 410 includes metadata 420 including a definition of a base profile, a resource list 430 defining a list of multimedia data, and a markup resource 440 .

[0057] The resource list 430 includes a single media resource 431 and a mixed media resource 432 . A single media resource 431 includes digital photo (Still), video (Video), digital audio (Audio), digital text (Text), print (Print), document (Document) and manifest link (ManifestLink). The mixed media resource 432 includes: digital photo + digital audio (StillWithAudio). Digital still multi-shot sequence (StillMultishotSequence), panorama digital photos (StillPanaormaSequence).

[0058] Therefore, in order to manage content by using the MPV document containing the resource list...

Abstract

A method and apparatus for reproducing multimedia data using a MusicPhotoVideo (MPV) profile. The method for reproducing multimedia data using a profile complying with the MPV standard, includes: detecting a reference element indicating that a predetermined profile among a plurality of supported profiles is used, in an MPV document; updating the MPV document using information on a profile corresponding to the detected reference element; and reproducing multimedia data by parsing the updated MPV document. Accordingly, by using the MPV standard profile, multimedia data can be reproduced more efficiently.

Description

technical field [0001] The apparatus and method according to the present invention relate to reproduction of multimedia data, in particular, to a method of reproducing multimedia data using a profile of the Music Photo Video (MPV) standard and a reproduction apparatus thereof. Background technique [0002] Digital cameras, digital video recorders, or digital audio reproducing devices supporting MP3 files, ie, MPEG audio files and WMA files (Microsoft WindowsMedia Audio files) are widely used. Therefore, various multimedia contents such as video, audio and document data need to be generated. [0003] Devices that generate these multimedia contents may generate metadata specifying properties of the generated contents, such as reproduction order or method of reproducing the contents, and may also generate the multimedia contents. For example, when photographs are taken using a digital camera, metadata defining properties such as the display order and dis...
