(59) As shown in FIG. 11, it is widely accepted in society that the choreography including yoga motion, exercise motion, and dance motion, has its own merchantability independently of music, not a subordinate element to music. Though the choreography using copyright-free music can be an independent product to sell and one can earn profit from selling the choreography, any organized system in which choreographers can produce and distribute the choreography efficiently does not yet exist. Thus, the present invention provides a platform in which the digital making is used in the choreography production rather than the conventional method to make the choreography in type of video contents and the choreography is provided to the users efficiently with SNS.

(60) Hereinafter, an embodiment of the apparatus for editing and playing video contents and the method thereof in accordance with the present invention will be described in detail.

(61) FIG. 12 is an exemplary diagram for explaining an apparatus for editing and reproducing video content in accordance with an embodiment of the present invention.

(62) As shown in FIG. 12 (a), the method of video contents editing in the present invention is as follows: the user enters the editing information related with the video contents (cue-point, section information, grouping information, additional information, and etc.) with the video contents editing UI (User Interface) (1000); generate a data file in transformed format by the interpreter (3000); and saves the said data file in the data file DB (4000).

(63) More specifically, the user performs reading of the original video contents with the said video contents editing UI (1000) and makes up the editing content such as cue-point insertion, section information, grouping information, additional information insertion, and etc. according to one's convenience. The said editing content is not included in the original video contents file but is transformed into a data file format with the said interpreter (3000), and the data file made by the said method is stored in the data file DB (4000) while the original video contents file remains intact as it is. In addition, the said data file DB is a database utilizing an internal storage, an external storage, a virtualized storage in a cloud computing network connected with the network, or combinations thereof.

(64) As described above, the method of video contents editing in the present invention is specifically not to edit and reconfigure the composition of the original video contents but to generate a data file containing cue-point, section information, and grouping information related to the content of the said video contents. The data file generated by this method can be used to play the said video contents section by section according to the user's convenience as if the video contents are directly edited. In fact, the video contents playback UI (2000) plays the corresponding part of the video content file for each section with the data file and the video content file is not divided according to sections of the video contents.

(65) The above cue-point is to for a user to create key frames as a data segment between the video images to the closest point in time that a user specified and the inserted cue-point is the smallest unit of editing. The cue-points can be inserted based on beats in music or equivalent periodic signals thereto and the insertion method using BPM (Beats per Minute) is illustrated in the present invention.

(66) The section information and the grouping information contain information on section and information on grouping of sections, respectively, according to the content of video contents; thus the original video contents can be played based on section and grouping information.

(67) The additional information contains content producer, a content-specific ID, title of content, content description (script), appropriate gender, choreography difficulty, play time, genre, thumbnail, and etc.; the user identify effectively a video content when playing the video content with the said data file.

(68) In addition, as shown in FIG. 12 (b), the method of video contents playback in the present invention is as follows: the user selects a video content to play with the video contents playback UI (20); the data file for the selected video content is loaded from the said data file DB (4000) and executed by the interpreter (3000). The video player (5000) plays the original video contents read from the video contents DB and controls the playback of the video content based on the said editing information in the said data file. In other words, the user can open the data file for a video content to play with the said video contents playback UI (2000) and control the playback of the original video contents by interacting with the video player (5000) based on the data file.

(69) On the other hand, the video contents data file in the present invention comprises a type of property list (Property List: plist). The said property list file is a file that records necessary information to execute an application program (or app); all apps have a property list and the extension name, plist, and the property list is called usually as plist. Typically the said property list file is used to save the user's setting but in the present invention it is used to generate the data file for video contents. In addition, the property list in the present invention uses XML document format, and the XML tag and the data saving format used in the XML property list file of the present invention is shown in Table 1.

(70) TABLE-US-00001 TABLE 1 XML Tag Type <string> UTF-8 encoding character string <real>, <integer> Decimal character string <true /> or <false /> Two kinds of tags <date> ISO 8601 type character string <data> Base64 encoding data <array> Child element number <dict> <key> tag and plist element related tag

(71) As shown in the above [Table 1], the XML tags used in the XML property list file of the present invention includes <string>, <real>, <integer>, <true/> or <false/>, <data>, <date>, <array>, <dict>, and the data saving format for each tag uses UTF-8 character string, decimal number string, two types of tags, ISO 8601 character string, Base64 encoding data, child element number, <key> tag, and tag related with plist element according to the order described above.
