The present invention relates to a method and a scheduling apparatus for scheduling a repetitive reproduction of a specific section of source media data, and more particularly, to a method and an apparatus for scheduling repetition order and number of repetitions of a particular source media data unit section.

Generally, when a user plays back data formed of audio or video using a media player (including an audio player such as a cassette, a CD player, or an MP3 player) and a video player such as a video, a user may repeatedly play a specific section. Occurs. In particular, in the case of language learning, the repetition of a specific section occurs more frequently.

To this end, various repetitive playback methods have been proposed. According to an embodiment, there is a method in which a repeat play button is separately placed in the media player, and the player plays a repetitive play by retreating for a predetermined time (for example, 4 seconds to 8 seconds) when the repeat play key is selected. In this case, the repetition frequency may be set in advance or may be set according to a user's selection.

In another embodiment, there is a method for allowing a user to directly set a unit section. That is, if a user selects a repeat play setting button at each of a start point and an end point of a section to be repeatedly played by providing a separate repeat play setting button in the media player, the section between the start point and the end point is repeatedly played. At this time, the repeat play count may be set according to a user's selection.

On the other hand, in recent years, language learning using audio data and video data played in a multimedia player that plays multimedia digital data such as a DVD player, a video CD player of a PC, a digital broadcasting TV (HDTV) having a storage device, and the like. There is a lot.

To this end, various methods have been proposed to facilitate repetition of specific sections of multimedia data.

For example, if a unit section is set during video playback, a method of synchronizing the audio data and the video data according to the audio tag of the corresponding section and the timing tag in the video data and repeatedly playing them together (application number: 10 -2000-0065300), a method of storing a playback repeat request section desired by a user in a predetermined memory and later reproducing only the stored playback repeat request section (patent application: 10-2000-0065890) has been proposed.

However, the conventional method for reproducing the unit section of the multimedia data has the following inconvenience.

First, the multimedia data includes various source media data such as image data, audio data, and the like. In the conventional multimedia data unit section playback method, these source media data can be synchronized and played together to separate the source media data. There was a problem that can not set each unit interval.

Second, in the case of language learning, there are sentences that make sense even if you listen to it once. Therefore, the user wants to repeatedly play the unit sections in the order that they set the schedule by setting specific parts of the video or audio of the part which is not understood by the unit section, but there is no way to implement them, and the number of playbacks according to the importance of the contents And there was no way to implement by specifying the playback period, playback order and the like as desired.

In order to solve the above problems, the present invention has been proposed, and it is an object of the present invention to separate a multimedia data to be played and to set a unit section of specific source media data only. In addition, even in a media player which plays only one type of media data, an object of the present invention is to enable various scheduling settings for the same type of media data. In addition, it is an object to repeatedly reproduce the unit intervals set from the source media data according to a predetermined repetition order and the number of repetitions. It is also an object of the present invention to provide a scheduling playback apparatus capable of repeatedly playing scheduled media data.

According to the present invention, in order to repeatedly play a specific section of multimedia data consisting of a plurality of source media data, the present invention provides a source media data selected from a user by selecting source media data to be repeatedly played among a plurality of source media data in the multimedia data. Outputting only, receiving unit sections from the output source media data, receiving a repetition order and number of repetitions of the designated unit sections, and repeatedly reproducing the unit sections according to the scheduling setting. Include.

In addition, in order to perform the above steps, the multimedia player calls the source media data calling module for calling and playing specific source media data, and the unit section setting module for setting specific unit sections of the played source media data as a unit section. And a unit section scheduling module configured to receive a repetition number and repetition order of the unit section from a user, and to set repetitive playback scheduling, and a media data scheduling apparatus including a unit section database for storing the repetition number and repetition order for each unit section. Equipped.

With the above multimedia unit section playback method and unit section playback apparatus, the user can repeatedly listen to the media data required by the user in the desired order.

For example, while watching a foreign currency, only a specific section of the image data can be listened to without silence and without audio and subtitles, or by repeatedly listening to the English dialogue audio, which can be helpful for language learning. In addition, it is possible to determine the repeat playback order for the media sections that the user wants to watch, thereby enabling efficient language learning.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

1A is a block diagram illustrating an internal configuration of a media data scheduling apparatus for repeatedly playing a specific section of multimedia data according to the present invention.

The source media data call module 102 functions to bring the source media data to be repeatedly played from the corresponding data source. The source media data is the source data required for multimedia playback. For example, when the DVD player plays a foreign currency DVD, the source media data corresponds to video data, foreign source audio data, and subtitle data. . Accordingly, the source media data call module 102 can call each source media data (image data, foreign language audio data, subtitle data) stored in the foreign currency DVD.

Similarly, when a digital broadcasting TV having a storage device receives a digital broadcasting channel and broadcasts a foreign currency, the source media data corresponds to video data, foreign language original audio data, translated language Korean data, and subtitle data. However, in the digital broadcasting TV, the source media data call module 102 does not directly call the source media data from the DVD like DVD repeat play, but additionally recognizes each broadcasting channel of the digital broadcast separately. With this, the source media digital data can be recalled.

That is, the digital broadcasting TV channel includes a video channel for transmitting video data, an audio channel for transmitting audio data, a data channel for transmitting subtitles and necessary information, a control channel for transmitting control data, and the like. In addition, the process of separating and recognizing each channel is additionally called.

The unit section designation module 104 receives a specific section of the source media data to be reproduced repeatedly from the user and stores the specific section of the source section data in the unit section database 110. Accordingly, the unit section designation module has various algorithms for designating a unit section. The unit section designation algorithm includes a unit section designation and storage step S310 of FIG. 3 and a unit section designation and storage step S910 of FIG. 9. Will be described in detail.

The unit section scheduling module 106 receives a user's setting in what order to repeat the specified unit sections and how many repeats are received from the user, and stores them in the unit section database 110, and further, according to the set repeat order and the number of repetitions. This module allows you to play unit sections repeatedly.

For example, the unit sections of the first source media data are designated as 1-A, 1-B, 1-C, and the unit sections of the second source media data are designated as 2-A, 2-B, and [1 -C, 4 repetitions]-> [2-A, 3 repetitions]-> [1-B, 3 repetitions]-> [1-A, 5 repetitions]-> [2-B, 1 repetition If the scheduling is set to repeat play in order, the unit section scheduling module 106 stores the set repeat order and the number of repetitions in the unit section database, and repeats the repeating units according to the set repeat order and the repeat count.

The unit interval database 110 is a database that stores the type, unit interval, repetition order, number of repetitions, and the like of the source media data to be repeatedly reproduced. An example of a table of the unit interval database is shown in FIG.

In FIG. 2, although the type of the first source media data is displayed as the image data and the type of the second source media data is shown as the audio data, this is merely an example and may be various source media data such as subtitle data as well as image data. It can be obvious.

The control unit 108 has an OS and a protocol for controlling the respective functional units so that the source media data is repeatedly played in a predetermined order in accordance with the present invention.

Each internal component block of the media data scheduling apparatus illustrated in FIG. 1A may be implemented in hardware, but in some cases, each component block may be implemented by a predetermined algorithm module. Accordingly, the media data scheduling apparatus shown in FIG. 1A is not a hardware module but a comprehensive concept including an algorithm module. The multimedia data scheduling apparatus includes a DVD player, a video CD player, a digital broadcasting TV (HDTV), and the like. It will be apparent that the same may be made of a hardware module or an algorithm module inserted into various multimedia players.

On the other hand, it is possible to implement a separate scheduling playback device that receives the scheduled source media data from the media data scheduling device and play it back, the internal block diagram of the scheduling playback device is shown in Figure 1b.

The scheduling data input module 152 is a function unit for receiving scheduling data from an external media data scheduling apparatus. Accordingly, in order to receive scheduling data from an external media data scheduling apparatus, the scheduling data input module is implemented as a wired terminal such as a serial communication input terminal or a short range wireless terminal such as Bluetooth or infrared communication. It is possible

The media data input module 153 is a component that receives the source media data to be played. The source media data input module refers to a means for reproducing through the play module by inserting and installing a storage medium containing the source media data. In addition, the source media data input module includes means for receiving the source media data from the outside and storing the source media data so that the source media data can be played by the playback module.

The memory module 154 is a module for storing data received from the scheduling data input module 152, and the scheduling data stored in the memory module 154 is used by the reproducing means at the time of reproducing. The playback is performed by the playback module according to the repetition order and the number of repetitions in which the unit sections of the source media data are the scheduling data stored in the memory module 154.

The playback module 156 is a playback device having a media playback function such as a speaker, a monitor, a digital player, and the like, and corresponds to all media players capable of playing back scheduling data from the media data scheduling device. The playback module 156 plays back the source media data according to the scheduling data stored in the memory module 154.

3 is a flowchart illustrating a process of repeatedly playing a specific unit section of multimedia data according to the media data scheduling apparatus.

First, when entering the unit interval setting mode (S302), the media data scheduling apparatus outputs the source media data included in the multimedia data (S304). For example, in the case of a digital broadcast TV with a storage device, the media data scheduling device in the digital broadcast TV is a list of the source media data which constitutes the multimedia data currently being broadcast (or the multimedia data stored in the internal storage device). Is output in a display format as shown in FIG.

The displayed area becomes a monitor window when the multimedia player is a moving picture CD player, and a CRT when the multimedia player is a DVD player or a digital broadcasting TV.

In the case of an audio player without a separate monitor window, the foreign source source media data output from the corresponding audio player are sequentially presented to the user, thereby allowing the user to select specific source media data (S306).

When the user selects (S306) specific source media data from the output source media data using the movement key 408 and the selection key 406 of the remote controller 400 shown in FIG. 4, the media data scheduling apparatus selects the selected source media data. The source media data is called and played back (S308).

The playback method is different depending on the type of the selected source media data. When the user selects the image data, only the image is played without audio and subtitles. When the English audio data is selected, the image, subtitles, Japanese audio, Korean Only English audio is played without audio.

When the selected source media data is reproduced (S308), the media data scheduling apparatus receives a unit section from the user and stores the unit section in the unit section database (S310).

As a method of designating a unit section, various methods may be proposed. Hereinafter, the designation method will be described.

The first method is to set the unit section based on the unit section division point by pressing the unit section setting key 402 during the playback of the source media data. That is, when the unit section setting key 402 is pressed during playback, the portion from the beginning of the source media to the point (unit section division point) inputted to the unit section setting key as shown in FIG. 6A is the first unit section 650. ; 1-a section). After that, when the second unit section setting key input (S604) is present, the second unit section (651; 1-b section) is set from the first input point (S602) to the second input point (S604). This is done. If there is no input of another unit section setting key until the end of playback after the second input of the unit section setting key (S602), the section from the second input of the unit section setting key (S604) to the end point of reproduction (S606) is performed. Unit intervals 652 and 1-c are set.

The second method of designating a unit section is to designate one unit section by pressing a unit section start key at the start point of the unit section and setting the unit section stop key at the end point to set the unit section among the source media data being played back. Thereafter, the unit section can be designated continuously by pressing the unit section start key and the unit section stop key while watching the video data continuously reproduced.

That is, as shown in FIG. 6B, the section desired to be repeated can be set by pressing the unit section start key and the unit section stop key while the specific source media data is being played back (S652 and S654). The start point and the end point of the unit section may be designated as a unit section based on a specific time zone using a time tag, or may be designated as a unit section based on a media data block unit tag. It will be obvious.

The third method of designating a unit section is to automatically designate the unit section when the unit section automatic designation key 414 of the remote controller is pressed without specifying the unit section. For example, when the automatic designation key 414 is pressed, the source media data is divided according to a preset time (for example, 10 seconds, 15 seconds, 20 seconds, etc.), and the unit interval setting can be made.

In addition, in the case of audio data, when the automatic designation key 414 is pressed, a repetition section is automatically set based on the silent point where there is no audio. For example, when the volume continues above a certain level and continues to be silent for a certain time below a certain level, the silence point is designated as the first repetition section.

As shown in FIG. 7A, the designated unit sections are stored in a table of indexes of the corresponding sections in the unit section database in a designated order 702 as shown in FIG. 7A.

When the unit section designation (S310) for the specific source media data is completed, the method (S312) asks whether to designate the unit section of another source media data. When the unit section of another source media data is to be designated (S312a), the unit sections are designated through the above steps S304, S306, S308, and S310.

For example, after designating a unit section of the first source media data (video data), and in the case of specifying a unit section of the second source media data (audio data), after the steps S304, S306, S308, and S310 are performed. As shown in FIG. 7B, the unit sections S712 designated in the second source media data are stored in the unit section database.

After the unit section designation is completed as described above (S312b), the unit section playback scheduling setting step (S314) is performed. That is, it has a step of determining in which order and how much to repeat the specified unit interval. Furthermore, the specific unit section can be set to repeat with no sound.

The scheduling setting is to set the repetition order and the number of repetitions for each unit section. The user may set the repetition order and the number of repetitions of the contents of the output unit section.

For example, in the case of an audio player that reproduces only audio, audio data is sequentially output for each section so that the user sets the repetition order and the number of repetitions of the corresponding section.

In the case of an image player (eg, DVD player, digital TV broadcasting) having a monitor capable of viewing an image, the repeating section, repeating order, and repeating number fields are displayed on the monitor window as shown in FIG. 8 for convenience of scheduling setting. do.

That is, when the user places the cursor S802 in a specific field by using the moving key 408 of the remote controller 400 and presses a selection key, the user may input the repetition order or the number of repetitions in the corresponding field. You can easily set the repeat count and repeat order for each section. If the user does not know the contents of the designated section, if the user places the cursor in the corresponding section and presses the select key, the contents of the corresponding section will be output, so that the user can set the scheduling after viewing or listening to the contents of the section. have.

On the other hand, when setting the number of iterations can be set to limit the output of the source media data. For example, in the case of audio data, the audio data may be set to be repeated in the silent state instead of the audio repeat playback of the corresponding section, and in the case of the video data, the video output may be set not to be output instead of the video repeat playback of the corresponding section. For example, if the number of repetitions of the corresponding unit section is set to 0, the unit section is repeatedly played in a silent state.

After the unit section designation step (S304, S306, S308, S310) and the scheduling setting step (S314), the contents as shown in FIG. 2 are stored in the unit section database.

After the unit section designation step (S304, S306, S308, S310) and the scheduling setting step (S314) are completed, when the user presses the unit section repeat key 404, the source media is set according to the unit section designation and scheduling setting contents. The data is repeatedly played back (S316).

For example, if scheduling is set as shown in FIG. 2, [1-C section, four repetitions]-> [2-A section, three repetitions]-> [1-B section, three repetitions ]-> [1-A section, 5 repetitions]-> [2-B section, 1 repetition] regeneration is performed.

In the present embodiment, the steps of specifying the unit section and repeating playback using the remote controller 400 have been described. However, in the case of a personal computer including a video CD player, the unit section designation and repeat playback are performed through a keyboard. It will be true.

In addition, although the present embodiment has described scheduling settings for various source media data in the multimedia data, it will be apparent that various scheduling settings can be made for the same source media data.

Meanwhile, the method of designating a unit section in the step of designating and storing the unit section has a problem in that the starting point of the unit section in the source media data being played must be designated by the user. In other words, before the scheduling setting of the repetition order and the number of repetitions is made, the user always has to designate the starting point of the unit section one by one.

In order to alleviate the inconvenience, the flowchart of FIG. 9 illustrates a method of directly performing scheduling setting without specifying a unit section.

When entering the unit interval confirmation mode (S902), it has a scheduling setting step (S904) for outputting the unit blocks of the original media data to set the iteration order and the number of iterations. The source media data is characterized in that the unit sections to be repeatedly reproduced in advance when the data is generated.

Therefore, when the unit interval checking mode is entered, the media data scheduling apparatus outputs predetermined unit intervals.

For example, in the case of an audio player, audio of each section of the corresponding source media data is output so that the user can set their repetition order and the number of repetitions.

After the scheduling setting for the specific source media data is finished, a step (S906) asking whether to set scheduling for another source media data is provided. When scheduling is set for another source media data, the repetition order and the number of repetitions are specified through the scheduling setting step (S904).

As described above, if the user presses the play key at any time after the scheduling setting is completed, the source media data is repeatedly played as scheduled contents (S908).

Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, the above-described embodiment is for the purpose of description, and various ordinary embodiments of the present invention may be made by those skilled in the art. I can understand.

As described above, the present invention can repeatedly play only specific source media data in the repeated playback of multimedia including a plurality of source media data, which helps the user to perform various language learning. In addition, in the media repeat playback that outputs the same media data, various scheduling of the media is possible, which is helpful for language learning. In addition, since the user can set the repetition order and the repetition frequency of the designated unit section, there is an effect of providing various repetitive playback methods.
