The present invention relates to a VoD service providing system using a media stream partitioning structure. The present invention relates to a VoD service providing system that inserts usage frequency and usage period information into each divided stream, and even if the user stops using the stream at a desired time, The present invention relates to a VoD service providing system using a media stream partitioning structure, which allows a user to use from an interrupted point at any time during the use frequency.

In the related art, in order to receive a VoD service, a user accesses a server providing a VoD service, pays a certain fee, and receives a VoD service using a media player.

However, if the VoD service provided by the obstacle of the Internet access service network such as a leased line is interrupted while receiving the VoD service, the existing stream is not divided and cannot be divided, so that the user provides the VoD service again. There is a problem of accessing the server and re-viewing the corresponding stream providing the VoD service from the beginning.

In addition, since it is necessary to access the server providing the VoD service and view the stream, it increases the traffic load on the network, and if the VoD service is interrupted in the middle, it must be executed again from the beginning. There is a problem of increasing the load due to.

In addition, when using the media streams on the Internet, it is difficult to guarantee the quality of service due to transmission delay and packet loss, and if the VoD service is interrupted due to the failure of the dedicated circuit network while receiving the VoD service, the corresponding VoD In order to use the service, there is a problem in that the disadvantage of having to pay the fee again.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to separate streams for providing VoD services at regular intervals, including information such as the number of times of use, duration of use for each stream, as well as download on the Internet. It is to provide VoD service efficiently by limiting the number of offline use.

In addition, by storing the stream in the user terminal to use the stream at any time the user wants, reducing the traffic load on the network due to the use of the stream on the Internet, iterative process of the VoD service providing system due to the interruption of the VoD service To reduce the load.

The present invention for achieving the above object, in the VoD (Video on Demand) service providing system for limiting the number of times and usage period of the media stream, the VoD content is divided into one or more streams and stream usage information for each stream A content database for storing; A user information database for storing contents details of the contents suspended during the user's use of the contents and starting time information of the usage; A user information analysis module that searches the user information database according to a VoD service request of a user and checks user information related to content suspended during use; And a stream control module for retrieving the corresponding stream requested by the user from the content database according to the confirmation result of the user information analysis module and recording the number of times of use and the period of use in the retrieved stream to the terminal of the user. Include.

The above and other objects and features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram illustrating stream splitting according to an exemplary embodiment of the present invention, and illustrates a stream structure in which one VoD video stream 1 is divided into n in a VoD system. That is, one VoD video stream 1 is divided into stream # 1, stream # 2 ... stream #n, and each of the divided streams has a stream name, serial number, time, frequency of use, usage period, and stream contents. And the like.

Each of the divided streams is sequentially provided when the user wants to view the streams, and the user receives the streams sequentially on the Internet or downloads them to the user's terminal to receive VoD service. At this time, if the user requests the interruption while transmitting the stream, the user can use the number of times determined by the user's terminal until the stream in which the existing stream is completed.

That is, when the user requests interruption while transmitting the stream and only the stream # 1 to the stream # 4 are transmitted, only the stream # 1 to the stream # 4 can be serviced. At this time, playback can be performed only as many times as the number of uses included in streams # 1 to # 4. Then, when the user requests stream transmission again, it is transmitted again after stream # 4 received, that is, stream # 5.

When all the streams are received in this manner, playback is possible for the specified number of times and the period of use stored in the stream.

2 is a configuration diagram of a VoD service providing system according to the present invention, wherein the VoD service providing system 10 includes a user information database 2, a user information analysis module 3, a content database 4, and a stream control module 5. Disclosed).

In this case, when the user 11 requests a stream for specific content, the user receives the content information through the user information analysis module 3, and requests for a stream that has been interrupted in the past, whether it is a stream requested by the user for the first time. Be sure to indicate acknowledgment.

The user information database 2 stores user information such as contents usage history of the user, contents details of the contents suspended during use, usage stop start time, usage stop end time, and search results for various contents.

The user information analysis module 3 receives a request for content to be used from the user 11, retrieves the content usage status and usage history of the user, information of the user 11, and the like from the user information database 2, and retrieves the user ( 11) to analyze the content to be provided to the user 1 to provide the corresponding content to the user through the stream control module (5). In addition, the result retrieved from the user information database 2 is received by the user 11 so that the user 11 can confirm whether or not the service continues.

On the other hand, when the user requests a subsequent stream for the interrupted content, the user information database 2 retrieves information such as a start point and a break point of the content, and provides a subsequent stream from the point of interruption of the content. .

The content database 4 stores contents of various stream contents so that the user can select desired contents.

The stream control module 5 receives the user request stream profile to provide the stream of the content requested by the user from the user information analysis module 2 described above, and retrieves the stream requested by the user from the content database 5 described above. To provide the stream to the user.

At this time, it checks the start and start information of each divided stream requested by the user, and includes the information of the corresponding contents such as stream name, serial number, transmission time, usage limit, and usage limit for each divided stream. By transmitting the information to the user 11 along with the stream, the user can recognize the information of the stream.

The user information database described above is provided through the user information analysis module 3 for information on the provided stream, such as which user is provided with what content through the above-described stream control module 5, and how many times the content stream is used. Update registration is made in (2).

3 is a flowchart illustrating a VoD service providing in a VoD service providing system according to the present invention.

First, when the user 11 transmits a specific stream to the VoD service providing system 10 (S30), the user information database 2 checks whether the user has previously received the selected stream. (S31).

If it is confirmed that the first stream is used, it indicates that the user 11 first transmits the selected stream, and transmits the stream to the user 11 through the stream control module 5 (S33). When the transmission is completed in this way, the usage record such as the time at which the stream is provided and whether the stream has been completely downloaded or only partially downloaded is stored (S34).

At this time, the user 11 is downloaded to the user terminal while viewing the stream on the Internet and can be interrupted during the transmission of the stream. If the user is interrupted, only the interruption part is stored in the user terminal. Usage information such as a part and an interruption time is stored in the user information database 2.

On the other hand, in the above-described step (S31), if the stream requested by the user 11 uses a portion of the existing, and if the use is interrupted during use, the user 11 is informed of the usage information on the stream, and previously used It is recommended to use the stored stream by indicating to the user 11 that the corresponding stream may already be stored in the terminal of the user 11 (S34).

At this time, it is determined whether the user 11 wants to receive the corresponding stream from the beginning again or after the interruption (S35), and if the user 11 wants to receive the corresponding stream from the beginning, the user In step S32, the corresponding stream is provided to the 11 from the beginning, and if only the stream after the interruption is desired, only the stream after the interruption is provided (S36).

On the other hand, in the above-described step (S31), as a result of the check that the user-requested stream has used all the way up to the end, in the case where the user 11 has previously seen the stream, the user information about the corresponding stream is used by the user ( 11), and informs the user terminal that the stream is already stored, and recommends using the stored stream (S37).

At this time, it is determined whether the user 11 receives the stream from the beginning or uses the stream stored in the user terminal (S38), and the user 11 sees the stream previously stored in the user terminal. You can use it at no extra charge. On the other hand, if the user 11 wants to view again from the beginning, it is preferable to deliver the stream from the beginning again (S32), and to make the stream subject to charge.                     

4 is a flowchart illustrating a VoD service using a user terminal according to an embodiment of the present invention.

First, the user 11 searches for information on a stored stream through the VoD viewer function of the user terminal (S40), and selects a desired stream (S41). Through the usage information of the selected stream, it is determined whether the selected stream has elapsed for a certain period or has exceeded a certain number of times of use (S42). If it has expired, the user 11 is notified that it has expired and ends (S43).

When the stream is not expired in the above-described step (S42), the total number of times of use and the number of times of use of the corresponding stream are checked (S44), and the corresponding stream is used (S45).

Thereafter, when the use of the stream is completed, the degree of use of the stream, that is, the total number of times of use and the number of times of future use, is stored for the used stream, and it is determined whether the number of times of use is expired (S46).

If the usage period and the number of times of use are expired in the above-described step (S46), the corresponding stream is automatically deleted or not available according to the expiration procedure, and then the usage history of the corresponding stream is stored and terminated (S47). On the other hand, if the contracted period of use and the number of times remaining, the information on the number of times available in the future forwarded to the VoD service providing system 10, the VoD service providing system 10 will provide information about this in the future use. (S48).

As such, when the interruption is made while using the stream, the interrupted information such as the interruption time and the interruption point of the stream is stored, and when the stream is to be used again later, the interruption information is used by using the interruption information described above. The stream is available from the beginning.

In addition, when a user pays a fee and downloads and uses a stream for the VoD service, the user can provide an efficient VoD service by allowing the user to view it again for free at any time.

As described above, according to the present invention, the user can download the stream at any time in a desired time zone, and can view the stream at a desired time at any time by a predetermined use period or the number of times, thereby providing an efficient VoD service to the user. It has an effect.

In addition, by allowing users to download streams at any time, stop and then download from the point of interruption, it is possible to reduce the traffic load on the network and reduce the repetitive process load in the VoD system. .

It will be apparent to those skilled in the art that various modifications, additions, and substitutions are possible, and that various modifications, additions and substitutions are possible, within the spirit and scope of the appended claims. As shown in Fig.
