Here, if the user selects a category in which at least one media data is stored, the device supports playback of all media data included in the category according to a setting method such as a sequential method or a random method.

On the other hand, the memory of the present device generally exceeds the unit of Giga, and the number of media data stored in the device is also increasing exponentially. In such a situation, it takes a lot of time and inconvenience to construct a playlist by selecting and selecting media data that the user desires to play or does not desire. Accordingly, the user generally views media data in a specific category as a single playlist, and plays the media data. However, in this case, unless the user deletes the undesired media data, the media data is continuously reproduced. If the user wants to play back the media data after a certain period of time has elapsed after the user deletes the corresponding media data, the user must download the corresponding media data again.

That is, the user may have media data that he / she wishes to listen to and / or view upon playback of the media data, and there may also be media data that he / she does not desire. However, there has been no method for identifying media data that the user does not desire in sequential playback of the media data by the conventional sequential method or random reproduction of the media data by the random method. Therefore, in the conventional media data reproduction method, media data that is not desired by the user is continuously and repeatedly reproduced in accordance with the sequential method or the random method. Consequently, even if the user does not want the media data, the user must continuously listen to and / or watch the media data belonging to the category.

Accordingly, the user disables the inconvenience described above by deleting the media data which is not desired to be reproduced at present. However, the user may desire again the previously deleted media data when a predetermined time elapses. In this case, the user is inconvenient to retrieve the media data again and store it in the device. In this case, unnecessary additional costs may be incurred due to purchase of media data. As a result, it is inconvenient to listen to and / or view unwanted media data in the conventional media data playback method, inconvenience of the procedure of storing the deleted media data, and time loss and unnecessary additional costs And the like.

In the embodiment of the present invention, the media data may include all types of data that can be reproduced in the device, such as music data, broadcast data, photo data, and image data. Hereinafter, a media data reproducing method, an apparatus and a system thereof of a device will be described with reference to the media data as an example in the following embodiments of the present invention.

Hereinafter, a device according to an embodiment of the present invention, a control method for reproducing media data in the device, and a system thereof will be described. It should be noted, however, that the device of the present invention, its control method, and its system are not limited or limited by the following description, and thus can be applied to various embodiments based on the following embodiments.

1 is a diagram illustrating a method of reproducing media data in a device according to an embodiment of the present invention.

Referring to FIG. 1, the device can execute a playback mode for playing media data according to a user operation (Step 101). At this time, the reproduction of the media data in the reproduction mode may be reproduction of all the media data in a specific category, or reproduction of all the media data of the device. For example, the device can store 100 media data, and 30 media data classified by the user among the 100 media data can be stored in the category A (category A). In this case, the user can perform playback of all of the 100 media data or playback of 30 media data in the A category.

Next, the device can configure a playlist for media data in the category designated in the play mode (step 103). For example, as described above, it is possible to construct a playlist for 100 media data or a playlist for 30 media data in the A category. At this time, the order of the media data in the playlist may be determined according to a random play scheme or a sequential play scheme.

In the case of the random reproduction method, all the media data can be reproduced in random order according to the set algorithm of the media data in the reproduction list. In the case of the sequential method, the media data in the reproduction list is sorted in the order of the list , Date order, artist name order, storage order, etc.) from the highest order to the lowest order of the media data. The device may classify the reproduction order of the media data in the reproduction list when the reproduction list is constructed as described above, and determine the corresponding media data having the highest reproduction order corresponding to the reproduction order. Here, the media data of the highest playback order may be media data existing at the highest level in the sorting method in the sequential manner as described above, or arbitrary media data determined at the playback time in the random mode.

Next, the device checks option information of media data of the sequence number to be currently reproduced in the playlist (step 105). That is, the device may check option information on the media data in the file system. According to an embodiment of the present invention, when the header of the media data includes option information, the media data may be parsed to check the option information added to the header of the media data. Although FIG. 1 shows the operation of checking the option information of the media data of the current playback sequence, in the media data scan operation for the playlist configuration, an option set in the header of the file system or media data Information on all media data in the list may be checked using the information, and the media data for which the skip function is set may be collectively identified.

Meanwhile, the file system prepares to read, write and search data in a storage unit in order to record data. The file system arranges the rules of the preparation, names each data, and stores corresponding data Where the system is located. Examples of such file systems include File Allocation Table (FAT), New Technology File System (NTFS), Journal File System (JFS), Unix File System (UFS), Extended File System (XFS) , ext 2 (extended file system 2), RaiserFS, or the like. The file system includes a format for setting a path to the corresponding data through a data storage structure (e.g., a directory structure). In addition, in the embodiment of the present invention, the file system may additionally include option information on media data.

Such a file system can be largely divided into a user data area and a meta data area. The metadata area is an area having general information about the file system. The metadata area includes a first area indicating a type, a size, and a status of a file system, a type of data, a permission, an owner a second area indicating information on data attributes such as owner, group, size, and the like. In an embodiment of the present invention, the file system may include a third area indicating option information generated according to a skip function setting for specific media data. In the third area, if the media data has the skip function, the respective fields including the skip information and the option information of the restriction information can be generated. If the restriction information of the corresponding media data expires or the skip function is not set The option information of the third area may be omitted.

Referring back to FIG. 1, the device determines whether the media data includes skip information according to the option information check in step 105 (step 107). The device can determine whether skip information is included in the corresponding media data using either the file system or the media data header according to the proposed embodiment. That is, in the embodiment of the present invention using the file system, the device can determine whether there is skip information by checking the third area for the media data in the file system. In addition, in the method of the present invention in which option information is added to the media data header, the device can determine whether or not there is skip information in the header of the media data.

If it is determined in step 107 that the media data includes the skip information, the device may compare the restriction information of the media data with the current information (current time, etc.) (step 109). That is, the device can check whether the restriction information of the media data includes current information of the device. Here, the device may acquire the limitation information from the third area of the file system or from the header of the media data, corresponding to the method of determining whether the skip information is included or not. The restriction information may be set to a specific date, a specific time, a specific date & specific time, a predetermined period, etc., and the device may compare the restriction information set in any one of the above- .

Next, when the restriction information includes the current information of the device, the device skips playback of the media data (step 111). That is, it is possible to omit the reproduction of the media data and to enter the reproduction procedure for the next sequential media data.

Next, if it is determined in step 107 that the media data does not include skip information, or if the determination information in step 109 and the limitation information do not include the current information of the media data, The audio component and / or the video component can be output (Step 121). In step 123, the device completes the reproduction of the media data for the reproduction of the media data.

Next, the device can check whether there is media data of the next order in the play list after completing the play of the media data in step 123 or skipping the play of the media data in step 111 Step 125).

Next, if it is determined in step 125 that there is media data of the next sequential number, the device may check the option information of the next sequential media data, and proceed to step 107 to perform the above-described process. On the other hand, if it is determined in step 125 that there is no media data of the next sequential number, the device can end the playback mode of step 101 (step 129). Here, if the repeat playback function is set in the setup mode for the user's playback mode, the end of the playback mode may be terminated by the user's request to end playback of the media data.

As described above, in the embodiment of the present invention, a header of a file system or media data can be used as a method for selectively reproducing media data. The device may check the option information added to the header of the file system or the media data when reproducing the media data to reproduce the media data or skip the reproduction thereof. Specifically, the device firstly checks whether the corresponding media data is media data to be skipped through the skip information of the option information. If the media data is a skip target, the device compares the restriction information of the option information with the current information of the device And it is possible to discriminate whether or not the media data is included in the skip object. If the restriction information includes the current information, the device skips the corresponding media data, and if the restriction information does not include the current information, the device reproduces the corresponding media data.

Hereinafter, with reference to FIG. 2 and FIG. 3, a brief description will be given of an operation of setting option information on media data in a device according to an embodiment of the present invention, and a format of media data in which the option information is set. However, it should be noted that the operation and media data format of the device of the present invention are not limited to or limited to the following description, and thus can be applied to various embodiments based on the following embodiments. For example, a skip function for the corresponding media data is added to the header of the media data as option information, or a skip function for the corresponding media data is added to the area allocated for the corresponding media data in the file system as option information It is possible.

2 is a diagram illustrating an example of a screen for setting option information for media data in a device according to an embodiment of the present invention.

Referring to FIG. 2, reference numerals 210 and 250 are examples of a list screen of media data provided by the device of the present invention. In an embodiment of the present invention, the list screen may include a music data list screen, a broadcast data list screen, a photo data list screen, a video data list screen, and the like, as a screen including at least one media data. In the following description, the list screen of the present invention will be described by exemplifying a list composed of multiple lines, but may also be provided as a list screen composed of multiple lines and a lattice pattern.

On the other hand, the user can selectively set the option information to at least one piece of media data, which can skip the reproduction of the media data on the list screen provided with the reference numeral 210 or 250 by the skip function . Although the screen 210 and the reference numeral 250 are provided with a list including five pieces of media data, they are provided as a list including n (n is a natural number) media data according to the size of the device screen . In the case of media data which is out of a screen, navigation between the lists can be supported by a scroll bar control using a direction key or the like or a touch input such as drag, flick, or move.

Here, the option information setting may select specific media data, and may set option information for the specified media data using a menu option. At this time, the user can set the skip information and / or the restriction information in setting the option information. This will be described with reference to Table 1 below.

Referring to Table 1, an example of a restriction information setting for specifying a specific date (one day) in the case of the "AAA" media data and skipping the corresponding media data (AAA) in a specific date . In this case, the skip function of the media data (AAA) is temporarily released before and after the first day of the month of the restriction information.

Quot; CCC "media data, and skips the corresponding media data (CCC) for each specified day of the week. In this case, the skip function of the media data (CCC) is temporarily released on the remaining days except Monday, Wednesday, and Friday of the restriction information.

In the case of the above-mentioned "EEE" media data, a specific date section (Aug. 1 to Aug. 15) is designated and the corresponding media data (EEE) is skipped during a specified specific date section (Aug. An example of the restriction information setting is shown. In this case, the skip function of the media data (EEE) is released before Aug. 1, the skip function is activated from Aug. 1, and the skip function is performed by Aug. 15, Is released.

In the case of the above-mentioned "GGG" media data, a specific time interval (AM9: 00 to AM11: 00) is specified and the restriction information setting for skipping the corresponding media data (GGG) during the specified specific time period (AM9: 00 to AM11: 00) An example is shown. In this case, the skip function is activated from AM9: 00 to AM11: 00 of the restriction information, and the skip function is temporarily released from AM11: 00 to the next AM9: 00.

In the case of the "KKK" media data, only skip information is set without setting additional limitation information. In this case, the corresponding media data (KKK) can be skipped continuously until the user's option information, that is, the skip information is canceled.

Quot; MMM "media data, and skips the corresponding media data (MMM) for a specified specific date interval (one month in July). In this case, the skip function of the media data (MMM) is released before July of the limitation information, the skip function is activated from July 1, and the skip function is performed until July 31, The function is released.

Shows an example of a limitation information setting in which a specific time interval (PM6: 00 or later) is specified in the case of the above-mentioned "PPP" media data and the corresponding media data (PPP) is skipped during a specified specific time interval (PM6: 00 or later). In this case, the corresponding media data (PPP) is skipped from PM6: 00 every day, and the skip function is performed from AM12: 00 to PM6: 00 on the next day.

Shows an example of the restriction information setting in which the corresponding media data TTT is skipped during a specific day (month, month) and a time period (AM9: 00 to PM6: 00) for the "TTT" media data. In this case, the corresponding media data (TTT) is skipped every Monday and Friday from AM9: 00 to PM6: 00, and the remaining days except Monday and Friday and the skip function during AM and PM other than AM9: Is temporarily released.

As shown in Table 1, the user can set option information in various ways for each media data. Also, the skip information can be automatically marked when the user sets the restriction information, and the user can set skip information without setting additional restriction information. If no limitation information is set after setting the skip information of the user, the corresponding media data can be continuously skipped until the user releases the option information.

Referring to FIG. 2 again, the device can set option information for the corresponding media data in the file system when the option information for at least one piece of media data is set by the user as in the example of Table 1 . That is, it is possible to additionally set option information in the third area of the corresponding media data in the file system. Alternatively, the device may convert the format of the media data according to the setting method, and configure option information according to the user setting in the header part of the media data.

When the option information for at least one piece of media data is set by the user as described above, the device can select media data (skip media data) in which the option information is set and media data in which option information is not set Media data) can be distinguished and provided. Such an example is indicated by reference numeral 210 or 250.

In the case of the reference numeral 210, the skip media data 215 in which the option information of the list of media data is set is simply distinguished from the general media data. In the case of the reference numeral 250, 253, and 255, which are set while distinguishing the skip media data 215 in which the option information is set from the general media data.

In the case of media data whose limitation information expires, among the media data for which option information is set, as shown in Table 1 and Table 1, it can be incorporated into general media data in the list. For example, in the case of the "EEE" media data in Table 1, both the skip information and the limitation information are released when August 15 has elapsed and converted to general media data. After July, the option information of the skip information and the limitation information are all released and converted to general media data. In the case of the media data for which the restriction information expires, when the embodiment of the present invention uses the file system, the information added to the skip information field and the restriction information field added to the third area of the corresponding media data in the file system can be removed have. Also, when the embodiment of the present invention uses the header of the media data, skip information and restriction information added to the header of the corresponding media data may be removed.

In addition, according to the user setting method, when the restriction information does not include the current information of the device, the corresponding media data in which the option information is set is provided as general media data, or when the restriction information does not include the current information of the device , It can be continued to indicate that the data is the skip media data. For example, in the case of the "AAA" media data in Table 1, the skip function is activated only on the first day of every month, and the skip function is inactivated before and after the first day of the month. At this time, if the current information (for example, current date) of the device is not included in the first day of the limitation information, the "AAA" media data may be divided into skip media data in the list according to the setting method, Data.

3 is a diagram schematically illustrating an example of a media data format according to an embodiment of the present invention.

Here, the example of the media data format shown in FIG. 3 shows an example of the media data format applied when the embodiment of the present invention uses the header of the media data. If the embodiment of the present invention uses a file system, the media data format of FIG. 3 may be omitted and may have a general format.

3, the media data of the present invention includes a header field 310 and a payload field 350. The header field 310 includes an identification information field and an option field Area, and the identification information area may include an identification information field 311 for identifying a type of the corresponding media data. The option information area may include a skip information field 313 indicating that option information is set and a restriction information field 315 indicating setting information in which the skip function is activated corresponding to the skip information.

The device of the present invention can identify the type of the corresponding media data, for example, music data, broadcast data, or the like, by the identification information field 311. If the media data is skipped by the skip information field 313 Is set, that is, whether the option information is set or not, and the restriction information set for the media data can be identified by the restriction information field 315.

Accordingly, the device of the present invention firstly identifies whether or not the corresponding media data is media data to be skipped by parsing the header field 310 of the media data during reproduction of the media data or in the construction of the playlist for the media data If the media data is a skip target, the limitation information may be compared with the current information of the device to discriminate whether or not the media data is included in the skip object.

The device skips the media data if the limitation information includes the current information, and if the restriction information does not include the current information, the device reproduces the corresponding media data. In addition, if the device does not include any restriction information in the restriction information field 315 in the secondary determination based on the restriction information after the first determination by the skip information, the device determines that the corresponding media data is a skip object until the skip information is canceled And skips the corresponding media data.

In the foregoing, the operation of selectively checking the option information for the corresponding media data in the playback order of the media data in the device and selectively reproducing or skipping the corresponding media data has been described. 4, when the user plays the playback mode, the option information is checked at the time of constructing the playlist for the media data in the category, the media data set with the option information is removed from the playlist, An operation of reproducing media data by a playlist consisting of only media data will be described.

4 is a diagram illustrating another method for reproducing media data in a device according to an embodiment of the present invention.

Referring to FIG. 4, the device can execute a playback mode for playing media data according to a user operation (Step 401). At this time, the reproduction of the media data in the reproduction mode may be reproduction of all the media data in a specific category, or reproduction of all the media data of the device. For example, the device may store 100 media data, and 30 media data classified by the user among 100 media data may be stored in the category A (category A). In this case, the user can perform playback of all of the 100 media data or playback of 30 media data in the A category. The device may construct a playlist for 100 media data or 30 media data corresponding to the former or latter and play back the media data in the order determined by the playlist.

Next, in step 403, the device extracts media data including skip information among the media data included in the play list when the play list is constructed in the play mode. At this time, the device can check the option information area using the header of the file system or the media data. In step 403, the device can extract the skip information from the skip information field indicating whether the skip function is set or not have.

The device may temporarily store (i.e., buffer) meta information on the media data to be extracted first. In step 405, the device checks restriction information set on the corresponding media data when at least one piece of media data including the skip information is extracted. Here, the device may check the restriction information on each media data of the meta information that is primarily extracted and buffered. The device may check the option information area using the header of the file system or the media data. In step 405, the device extracts the restriction information from the restriction information field in which the restriction information is set in the option information area, ≪ / RTI >

Next, the device secondarily extracts the media data having the restriction information including the current information of the device according to the restriction information check (step 407). At this time, the device may temporarily store or buffer the meta information of the media data to be extracted secondarily. In step 409, the device removes the secondarily extracted media data from the playlist. At this time, the deletion from the play list indicates a form in which the corresponding media data is deleted only in the play list, not in the form of deleting the actual media data.

Next, the device reconstructs the playlist from which the extracted media data is removed (step 411), and processes the media data by the reconstructed playlist (step 413).

As shown in FIGS. 1 to 4, according to an embodiment of the present invention, the device confirms option information of media data and, when the corresponding media data satisfies both the skip information and the restriction information, Skip.
