FIG. 3 is a diagram showing an example of an overall environment for reuse of media content in one embodiment of the present invention. In the present embodiment, the server 310 may provide a service for providing the requested media content according to the request from each of the plurality of terminals 320. Here, each of the server 310 and the plurality of terminals 320 may be realized by the computer device 200 described with reference to FIG. 2, and the required media content is, for example, audio content such as a sound source and / or. It may include video content such as video. In the embodiment of FIG. 3, an example of a process in which the server 310 provides media content according to the request of the terminal 2 (330) is shown. Further, the server 310 may include the media content database 340 in which the media content is stored, or may cooperate with another system including the media content database 340. Further, the server 310 may include the collected information database 350 or may cooperate with another system including the collected information database 350. The collected information database 350 may be a database in which the server 310 collects and stores information on each user's usage pattern for media content. For example, information regarding the usage pattern of the first user for the first media content may be stored in the collected information database 350. As an example, assuming that there are 100 media contents and 100 users, information about up to 10,000 usage patterns may be stored in the collected information database 350. The data stored in such a collected information database 350 will be described in more detail below.

The request stage 361 may be an example of a process in which the terminal 2 (330) requests the server 310 for the specific media content A. As an example, the terminal 2 (330) may access the streaming server 310 via the network 170 using a specific URL and may request the media content A identified by the URL.

The acquisition step 362 may be an example of a process in which the server 310 acquires the media content A requested from the media content database 340. As an example, the server 310 may search and extract the media content A requested by the terminal 2 (330) from the media content database 340.

The collected information extraction step 363 may be an example of a process in which the server 310 extracts information regarding the user usage pattern of the terminal 2 (330) for the media content requested by the terminal 2 (330). As described above, the collected information database 350 may be a database in which the server 310 collects and stores information on each user's usage pattern for the media content, in which case the server 310 is the extracted media content. Information about the user usage pattern of the terminal 2 (330) with respect to A may be extracted from the collected information database 350.

Does the usage pattern analysis stage 364 allow the server 310 to reuse the data for reproduction of the media content A in the terminal 2 (330) based on the user usage pattern of the terminal 2 (330) for the media content A? It may be an example of the process of determining. For example, the server 310 calculates the probability that the media content A will be reused by the user of the terminal 2 (330) (hereinafter referred to as “reuse probability”), and the calculated reuse probability is a preset threshold value. In the above case, the reuse of the media content A in the terminal 2 (330) may be allowed. As a more specific example, when the preset threshold value is 70% and the reuse probability in the terminal 2 (330) with respect to the calculated media content A is 90%, the terminal 2 (330) of the media content A Reuse in is acceptable. Here, the permissible reuse means that the data for reproduction of the media content A is stored in the terminal 2 (330), and the media content A is stored using the stored data at the next reproduction for the media content A. It may mean allowing reproduction. The information collected in the collected information database 350 for calculating the reuse probability is not particularly limited as long as it is the information for calculating the probability that the user reuses a specific media content. , Preferably, it may include at least one of information about the reproduction time and information about the repeat reproduction period. Here, the reproduction time may mean the time when the user of the terminal 2 (330) reproduces the media content A (all or a part of the media content A), and the repeated reproduction period is the terminal 2 (330). ) The period taken from the user playing the media content A to playing the media content A again (when playing the media content A three times or more, the media content A is played n times (n is a natural number). ) The nth playback time point and the n + 1st time, such as the average period of time it took to play n + 1 times after playback, or the period calculated based on the most recent playback time point and the previous playback time point of media content A. (Statistical value based on the time of reproduction). For example, when the user of the terminal 2 (330) first plays the media content A in an amount of 2 minutes and 30 seconds, the entire media content A is played for 2 minutes and 30 minutes, and the media content is played 10 minutes after the first playback. When a part of the media content A is played for only 1 minute while playing A as the second time, and 20 minutes after the second play, the whole of the media content A is played for 2 minutes and 30 minutes, the terminal 2 (330). The reproduction time for the media content A of the user of) may be 6 minutes, and the repetitive reproduction period may be 15 minutes. As an example, the server 310 may calculate the reuse probability so that it has a relatively larger value as the reproduction time increases and / or the repeat reproduction period decreases.

Further, depending on the embodiment, the information collected may further include information regarding at least one of the usage time and the number of usages for the application installed and executed in the terminal 2 (330). For example, the server 310 may calculate the reuse probability so that it has a relatively larger value as at least one of the usage time and usage frequency for the application in terminal 2 (330) increases.

Further, depending on the embodiment, the collected information may further include information regarding the terminal reproduction environment. For example, information about the terminal playback environment includes the number of media contents contained in the user's playlist on terminal 2 (330), the repeat playback flag set in the playlist, and the availability of local storage on terminal 2 (330). It may contain at least one of the capacities. For example, it is determined that the larger the number of contents included in the playback list, the lower the probability that the media content A will be played again. Therefore, the server 310 is relative to the smaller the number of media contents included in the playback list. The reuse probability may be calculated to have a larger value. As another example, when the repeat playback flag is set for the media content A, there is a high probability that the media content A will be played again, so that the server 310 has the repeat play flag set for the media content A. The reuse probability may be calculated so that the case has a relatively larger value than the case where the repeat reproduction flag is not set in the media content A. Similarly, when the repeat playback flag is set for the entire playlist, the reuse probability is calculated so that it has a relatively larger value than when the repeat play flag is not set. good. As yet another example, the server 310 may calculate the reuse probability so that the larger the available capacity of the local storage, the larger the relative value.

At this time, the playback time, the repeated playback period, the usage time for the application, and the number of times of use may be information obtained from the history of the user of the terminal 2 (330), but on the other hand, the number of media contents included in the playback list. , The repetitive playback flag, and the available capacity of the local storage may be information collected at the time when the reuse probability of the media content A is to be calculated. In this way, the server 310 collects various information that can be collected for the media content A, the terminal 2 (330), and the user of the terminal 2 (330), and calculates the reuse probability of the media content A. You may use it for.

The provision stage 365 may be an example of a process in which the server 310 provides the data for reproduction of the media content A and the information regarding whether or not the data for reproduction can be reused to the terminal 2 (330). As an example, the server 310 sets the reuse flag for the media content A to 1 (reuse allowed) or 0 (reusable not possible) for playback of the media content A whose reuse flag is set to 1 or 0. Data may be transmitted to the terminal 2 (330). Such a reuse flag is only an example, and is installed and executed on the terminal 2 (330) and / or the terminal 2 (330) so that the server 310 reuses the data for playing the media content A. The method is not particularly limited as long as it is a method capable of transmitting an instruction for controlling an application to the terminal 2 (330).

The reproduction and storage step 366 is a process in which the terminal 2 (330) reproduces the media content A using the received data and stores the data in the local storage of the terminal 2 (330) depending on whether or not the data can be reused. It may be an example of. As an example, the terminal 2 (330) may play the media content A using the received data according to the control of the application, and save the received data when the reuse flag is set to 1. good. After that, when trying to play the media content A again on the terminal 2 (330), the media content A is played again using the stored data without requesting the media content A from the server 310. It becomes possible. When the reuse flag for the media content A is set to 0 and received, the terminal 2 (330) may re-request the media content A from the server 310, and the above-mentioned steps 361 to 366 may be re-executed. ..

At this time, in the reproduction and storage step 366, the information regarding the reproduction of the media content A may be collected in the server 310 by the reproduction of the media content A, and the collected information database 350 may be updated. Further, the usage time and / or the number of usages of the above-mentioned application may differ depending on the time when the media content A is requested. Further, the number of media contents included in the playlist of the user of the terminal 2 (330), the repeated playback flag set in the playlist, and / or the available capacity of the local storage of the terminal 2 (330) are also the media contents A. May vary depending on the time of request.

In other words, the reuse probability of the user of the terminal 2 (330) for the media content A may differ depending on the time of request for the media content A and / or the time of calculation of the reuse probability. As a result, the data stored in the local storage of the terminal 2 (330) may be deleted depending on the time point, or the storage time may be increased. The storage time of such data will be described in more detail below.

Further, the user of the terminal 2 (330) may reproduce the entire media content A, but may repeatedly reproduce only a part of the media content A. In this case, it is not efficient to store the entire data in order to reproduce the media content A. For this purpose, the server 310 collects information on the usage pattern for each user for each section of the media content A, calculates the reuse probability for each section, and thereby reproduces a part of the section of the media content A. The data may be controlled to be stored in the local storage of the terminal 2 (330). The preservation of some sections will be described in more detail below.

In the above, the embodiment in which the reusability is set only for the media content A and the terminal 2 (330) has been described. However, such an embodiment describes each of a large number of media contents that can be provided by the server 310 and the server. It can be easily understood by those skilled in the art that it can be applied to each of a large number of users (terminals of a large number of users) who can connect to the 310 and receive media content. Let's do it.

Further, an application linked with the server 310 may be installed and executed in each of the user's terminals, and media content request, reproduction, storage, and the like in each of the terminals may be executed in accordance with the control of such an application.

FIG. 4 is a diagram showing an example in which a part of media content is stored and reused in one embodiment of the present invention. FIG. 4 shows an example of the media content 410 divided into six sections 1 to 6. At this time, in the media content 410, it is assumed that the section corresponding to the first range 420 is a section repeatedly reproduced by the user. In this case, in the sections 3, the section 4, and the section 5, the reproduction time is increased, but the repeated reproduction period is shortened. In other words, the reuse probabilities for sections 3, 4, and 5 will have relatively higher values than the reuse probabilities for sections 1, 2, and 6. If the reuse probability for section 3, section 4, and section 5 is greater than or equal to the threshold and the reuse probability for interval 1, section 2, and interval 6 is less than or equal to the threshold, the server 310 will perform section 3, section 4, and. An instruction for controlling the application to reuse the section 5 on the user's terminal may be generated and transmitted to the corresponding terminal together with the media content 410. For example, the generated instruction may correspond to setting the reuse flag for each of section 3, section 4, and section 5 to 1. In this case, the terminal may save the section 3, the section 4, and the section 5 in the local storage of the terminal while playing the media content 410. After that, the terminal can reproduce the section corresponding to the first range 420 by using the information about the section 3, the section 4, and the section 5 stored in the local storage. Depending on the embodiment, the header for playing the media content 410 may be stored separately. For example, when the section 1 includes a header for reproducing the media content 410, the header included in the section 1 or the section 1 may be additionally stored in the local storage.

The section of the media content may be arbitrarily divided, but in the streaming service, it is preferable that the section is divided in units of segment files generated by separating the media content in order to provide the streaming service for the media content.

FIG. 5 is a diagram showing an example in which a retention period of media content is set and reused in one embodiment of the present invention. FIG. 5 shows an example in which the media content 1 (data for reproducing the media content 1) (530) is stored in the local storage 520 of the terminal 510. At this time, the storage period may be set for the media content 1 (530). For example, the server 310 analyzes the information collected corresponding to the user of the media content 1 (530) and the terminal 510 from the collected information stored in the collected information database 350, and the terminal of the media content 1 (530). The retention period at 510 may be determined. The determined retention period may be transmitted to the terminal 510, which may set the retention period of the media content 1 (530) according to the control of the application installed and executed on the terminal 510. The format of the storage period is not particularly limited as long as it is a data format that can indicate how long the media content 1 (530) can be stored in the local storage 520.

On the other hand, as described above, the reuse probability of the media content 1 (530) may be calculated differently depending on the time when the media content 1 (530) is requested or the time when the reuse probability is calculated. Similarly, the retention period of the media content 1 (530) may be different. For example, the longer the time during which the media content 1 (530) is not played on the terminal 510, the lower the reuse probability of the media content 1 (530), and the longer it is not necessary to store the media content 1 (530). Therefore, the server 310 updates the user usage pattern of the terminal 510 for the media content 1 (530) collected and stored in the collection information database 350, whereby the (1) media content 1 (530) for the user of the terminal 510 is updated. ) May be recalculated, and (2) the retention period of the media content 1 (530) may be updated. Further, the server 310 transmits (3) the updated storage period of the media content 1 (530) to the terminal 510, and (4) the terminal 510 updates the storage period of the media content 1 stored in the local storage 520. It's okay. In other words, the terminal 510 may update the retention period of the media content 1 (530) stored in the local storage 520 according to the updated retention period transmitted from the server 310. As an example, the retention period may be updated so that the lower the reuse probability, the shorter the retention period, and the higher the reuse probability, the longer the retention period.

FIG. 6 is a flowchart showing an example of a method of reusing media contents in one embodiment of the present invention. The method of reusing the media content according to the present embodiment may be executed by the computer device 200 that realizes the server 310 described above. For example, the processor 220 of the computer apparatus 200 may be implemented to execute a control instruction by the code of the operating system included in the memory 210 and the code of at least one program. Here, the processor 220 causes the computer device 200 to execute the steps 610 to 650 included in the media content reuse method of FIG. 6 according to the control instruction provided by the code stored in the computer device 200. You may control it.

At step 610, the computer device 200 may serve a large number of media contents to a large number of users over the network. As an example, the media content may be streamed to the user's terminal by a streaming method.

At step 620, the computer device 200 may collect information about each user's usage pattern for media content. The information about the usage patterns collected may include the reproduction time of the media content and at least one of the repetitive reproduction periods taken after the media content is reproduced and before it is reproduced. Depending on the embodiment, information about at least one of the user's usage time and usage frequency for an application installed and executed on each user's terminal may be further collected. In other embodiments, at least one of the number of media contents contained in each user's playlist, the repeat playback flag set in the playlist, and the available capacity of each local storage of the user terminal is further collected. May be done.

At step 630, the computer device 200 may receive a request for first media content transmitted by the first user's terminal under the control of an application installed and executed on the first user's terminal.

In step 640, the computer device 200 reuses the data for reproducing the first media content on the terminal of the first user based on the usage pattern of the first user for the first media content among the collected usage patterns. You may generate instructions to control the application to do so.

As one embodiment, in stage 620, the computer apparatus 200 plays the first media content again after the play time in which the first user plays the first media content and the first user plays the first media content. At least one of the repetitive regeneration periods that took to make it occur may be collected. At this time, the computer device 200 may collect at least one of such playback time and repetitive playback period for each media content and for each user. In this case, in step 640, the computer device 200 calculates the reuse probability of the first media content by the first user based on at least one of the playback time and the repeated playback period, and the calculated reuse probability is calculated. The instruction may be generated when the value is equal to or higher than the threshold value.

As another embodiment, the computer device 200 may further collect information about at least one of each user's time and number of uses for the application at stage 620. In this case, the computer device 200 may calculate the reuse probability in step 640 further based on at least one of the usage time and the number of uses. For example, the computer device 200 may calculate the reuse probability based on at least one of the reproduction time and the repeated reproduction period and at least one of the utilization time and the number of uses.

As another embodiment, the computer apparatus 200 has, in stage 620, the number of media contents included in the playlist of the first user, the repeat playback flag set in the playlist, and the local storage of the terminal of the first user. At least one of the available volumes may be further collected. In this case, the computer device 200 may calculate the reuse probability in step 640 further based on at least one of the number of media contents, the repeat playback flag, and the capacity. For example, the computer device may calculate the reuse probability based on at least one of the play time and the repeat play period and at least one of the number of media contents, the repeat play flag, and the capacity.

In step 650, the computer device 200 may transmit the generated instructions to the terminal of the first user together with the data for reproducing the first media content. At this time, the application installed on the terminal of the first user stores the data for reproducing the first media content in the terminal of the first user according to the above command, and the reproduction request for the first media content is made by the first user. When it occurs in the terminal of the first user, the data for playing the first media content stored in the terminal of the first user may be reused to play the first media content in the terminal of the first user. .. Such an application may be installed and executed on each user's terminal that connects to the computer device 200 and requests media content.

Further, according to the embodiment, the computer device 200 determines the retention period of the first media content in the terminal of the first user based on the usage pattern of the first user for the first media content among the collected usage patterns. good. In this case, the computer device 200 is determined in step 650 so that the period for storing the data for playing the first media content in the terminal of the first user is set to the storage period determined by the application. The retention period may be further transmitted to the terminal of the first user. Further, when the usage pattern of the first user for the first media content is updated, the computer device 200 may update the retention period determined based on the updated usage pattern. In this case, the computer device 200 updates the storage so that the period for storing the data for playing the first media content in the terminal of the first user is dynamically updated to the storage period determined by the application. The period may be transmitted to the terminal of the first user.

Further, depending on the embodiment, the computer device 200 may collect information on the usage pattern for each user for each section of the media content in the stage 620. In this case, in step 640, the computer device 200 calculates the reuse probability by the first user for each section of the first media content based on the usage pattern of the first user corresponding to each section of the first media content. An instruction for controlling the application may be generated so that the data for reproduction in the section where the calculated reuse probability is equal to or greater than the threshold value is reused on the terminal of the first user. In this case, among the sections of the first media content, the data for reproduction of the section in which the calculated reuse probability is equal to or higher than the threshold value may be stored in the local storage of the terminal of the first user. Further, the reproduction of the stored section of the first media content may be executed by using the data stored in the local storage. At this time, as described above, the header of the first media content may be further stored in the local storage in order to search for a specific section from the first media content.

FIG. 7 is a flowchart showing an example of a method of reusing media contents in another embodiment of the present invention. The media content reuse method according to the present embodiment is a terminal of the user described above (as an example, one of a plurality of terminals 320 described with reference to FIG. 3, or a terminal 510 described with reference to FIG. 5). ) May be executed by the computer device 200. For example, the processor 220 of the computer apparatus 200 may be implemented to execute a control instruction by the code of the operating system included in the memory 210 and the code of at least one program. Here, the processor 220 causes the computer device 200 to execute the steps 710 to 770 included in the media content reuse method of FIG. 7 according to the control instruction provided by the code stored in the computer device 200. You may control it.

At step 710, the computer device 200 may access the server via the network, receive media content from the service provided by the server, and play the content. Here, the server may correspond to the server 310 described with reference to FIGS. 3 and 5, or the server realized by the computer device 200 described with reference to FIG. As an example, the server may provide media content by a streaming method.

At step 720, the computer device 200 may transmit information about user usage patterns for media content to the server. The server may collect information about such usage patterns from each of a number of terminals, such as the user's terminal, realized by the computer device 200 according to the embodiment of FIG. In other words, the server may serve a large number of media contents to a large number of users via a network and collect information on each user's usage pattern for the media contents. As an example, the computer device 200 has at least one of a reproduction time for reproducing the first media content and a repetitive reproduction period taken from the reproduction of the first media content to the reproduction of the first media content again. Information may be sent to the server. The user usage pattern for such the first media content may be stored in the server, and may be subsequently utilized to determine whether or not the first media content can be reused when the first media content is requested. The various factors that determine the propriety of such reuse are as described in detail above.

At step 730, the computer device 200 may request the server for the first media content via the network in accordance with the playback request for the first media content.

At step 740, the computer device 200 may receive data for playing back the first media content and instructions for storing the data for playing back from the server. The instruction may be generated by the server by determining that the server reuses the first media content in the user's computer device 200 based on the user usage pattern for the first media content.

At step 750, the computer device 200 may reproduce the first media content using the received data for reproduction.

In step 760, the computer device 200 may store the received data for reproduction in the local storage according to the instruction.

In step 770, when the computer device 200 also reproduces the first media content, the computer device 200 may reproduce the first media content using the stored data for reproduction.

In this way, the computer device 200 can store and reuse the media content provided by the server based on the instructions provided by the server. Therefore, since the media content does not need to be re-provided, the usage of communication data can be reduced, and by storing the frequently used sound source in the local storage of the computer device 200, the computer device 200 is in the offline state. Can also be used. Also, instead of storing all the media content to be played in the local storage, only the media content allowed by the server based on the user usage pattern is selectively stored in the local storage and reused, so that the capacity of the local storage can be reused. Can also solve the problem caused by.

As another embodiment, the computer apparatus 200 may further receive information about the retention period of the first media content from the server, and the retention period is set as the retention period of the data stored in the local data for reproduction. good. If the retention period expires thereafter, the computer device 200 may delete the data for reproduction from the local data. Such a retention period may be dynamically updated with the update of the user usage pattern collected by the server. By removing the media content whose reuse probability has decreased due to the management of the retention period from the local storage, it is possible to reduce the amount of data in the local storage required for the reuse of the media content.

As another embodiment, the computer device 200 may generate information about the user usage pattern for each section of the media content and transmit it to the server in the stage 720. In this case, the computer device 200 may store in the local storage the data for the section identified by the instruction among the received data for reproduction in the stage 760. In this way, by storing the data for the sections frequently used by the user in the local storage, it is possible to reduce the amount of data stored in the local storage rather than storing the entire media content.

As described above, according to the embodiment of the present invention, information on the user-specific usage pattern for the media content is collected, and the reuse for the media content is performed based on the user-specific usage pattern collected for the media content. By deciding whether or not to allow it, the media content can be reused efficiently.
