In addition, a new function of differentiated reproduction of media content through coding can be provided to the user, thereby inducing the user's interest in coding learning.

Hereinafter, a process of coding a reproduction algorithm by the coding apparatus 100 will be described.

24 is a flowchart illustrating a process of coding a reproduction algorithm in a coding apparatus according to an embodiment.

Referring to FIG. 24, the coding apparatus 100 recognizes a first media content code, which is a dot code corresponding to first media content information, from a first media content card selected by a user (S2410). Before the step S2410, the coding apparatus 100 may recognize a coding command code corresponding to the coding command information “start” from the coding command card on which “start”, which is coding command information indicating the start of coding, is printed.

Recognizing the first media content code, the coding apparatus 100 sequentially recognizes N command codes for configuring the first play condition, which is the play condition of the first media content, from the N coding command cards (S2420). Here, the first playback condition is a first playback volume condition that is a playback volume condition of the first media content, a first repeat playback condition that is a repeat playback condition of the first media content, and a first playback tone that is a playback tone condition of the first media content. It may include one or more of the conditions.

After the step S2420, the coding apparatus 100 recognizes a second media content code, which is a dot code corresponding to the second media content information, from the second media content card selected by the user (S2430).

Recognizing the second media content code, the coding apparatus 100 sequentially recognizes the M command codes for configuring the second play condition, which is the play condition of the second media content, from the M coding command cards (S2440). Here, the second playback condition is a second playback volume condition that is a playback volume condition for the second media content, a second repeat playback condition that is a repeat playback condition for the second media content, and a second playback tone color that is a playback tone condition for the second media content. It may include one or more of the conditions.

The coding apparatus 100 codes the playback algorithm of the media content group using the first media content code, N coding command codes, second media content codes, and M coding command codes (S2450).

Here, the media content group includes first media content and second media content, and may further include one or more media content.

In other words, the coding apparatus 100 may further recognize one or more media content codes and a plurality of coding instruction codes after step S2440.

And in the step S2450, the first media content code, N coding command codes, second media content codes, M coding command codes, one or more media content codes, and a plurality of coding command codes are combined according to the code recognition order and reproduced. It can be coded with an algorithm.

After coding the reproducing algorithm of the media content group as described above, the coding device 100 recognizes a storage command code and a predetermined bookmark code from the card printed with "Save" and the card printed with predetermined bookmark information as shown in FIG. can do. Here, the storage command code is a dot code that instructs storage of the reproduction algorithm.

Recognizing the storage command code and the predetermined bookmark code, the coding apparatus 100 may convert the predetermined bookmark code into predetermined bookmark code information, and store the predetermined bookmark code information in correspondence with the playback algorithm.

Thereafter, the coding apparatus 100 may recognize only a predetermined bookmark code.

In this case, the coding apparatus 100 may convert the predetermined bookmark code into predetermined bookmark code information, and check whether the predetermined bookmark code information and a corresponding reproduction algorithm are previously stored.

If the playback algorithm is previously stored, the coding device 100 selects and plays media contents included in the media content group from a plurality of previously stored media contents according to the playback algorithm. The condition can be set as the playback condition of the first media content and played.

In addition, when the second media content is played after the playback of the first media content is completed, the preset first playback condition may be changed to the second playback condition and played.

Hereinafter, a process in which the coding apparatus 100 reproduces a plurality of media contents according to a reproduction algorithm will be described.

25 is a flowchart illustrating a process of playing a plurality of media contents according to a playback algorithm in a coding apparatus according to an embodiment.

Referring to FIG. 25, after coding a playback algorithm in step S2450, the coding apparatus 100 selects media contents included in a media content group from a plurality of previously stored media contents (S2510).

Thereafter, the coding device 100 plays the selected media contents according to the playback algorithm, but sets the playback condition of the first media content as the first playback condition and plays, that is, plays the first media content according to the first playback condition. Do (S2520, S2530).

Here, the first playback condition may include a first playback volume condition, and the coding apparatus 100 may output a playback sound of the first media content at a volume corresponding to the first playback volume condition.

After completing the playback of the first media content, the coding device 100 can play the second media content after changing the first playback condition, which is the existing playback condition, to the second playback condition, which is the playback condition for the second media content. Yes (S2540, S2550). Here, the second playback condition may include a second playback volume condition, and the coding apparatus 100 may output the playback sound of the second media content at a volume corresponding to the second playback volume condition.

The coding apparatus 100 may terminate the process after performing the process of playing the remaining media content included in the media content group as in step S2550 (S2560).
