1 is a block diagram illustrating a configuration of a content providing system according to an exemplary embodiment. According to FIG. 1, the present content providing system 100 includes a service providing unit 110 and a copyright management server 120.

The content providing system 100 is a system capable of copyright management of content, and may provide a service by determining whether content is copyrighted. Here, the content may be, for example, a music file, a video file, or the like.

The copyright management server 120 determines whether or not the service is available according to the copyright of the content provided from the source, and the service provider 110 provides the content determined to be serviceable by the copyright management server 120. It plays a role.

Hereinafter, a case where the content is sound source data reproduced from an audio CD will be described by way of example.

The content providing system 100 is a system capable of copyright management of a sound source of an audio CD. The content providing system 100 may provide a download service, a streaming service, and the like to a serviceable sound source by determining the copyright of the sound source of the audio CD.

The service provider 110 serves to provide a service for a sound source of an audio CD. The service providing unit 110 may include a service server (downloading service server, streaming service server, etc.) capable of actually serving the service, or may be configured in a form in which the service server is separately configured. However, hereinafter, a case in which the service server is implemented in a form separately configured from the service providing unit 110 will be described for convenience of description.

The copyright management server 120 manages the service availability of the sound source of the audio CD, and serves to provide a service-enabled sound source to the service provider 100.

FIG. 2 is a schematic diagram for briefly describing an operation of the content providing system illustrated in FIG. 1.

According to FIG. 2, when the audio CD 130 including the sound source to be serviced is inserted into the CD-ROM, the DISCID of the audio CD is transmitted to the copyright management server 120. The copyright management server 120 may determine whether a service is available for each sound source using the DISCID of the audio CD and the pre-stored data. In particular, it is possible to determine whether the service is available for all or part of the sound source included in the audio CD, and if the service for some is possible, it is also possible to determine some serviceable sound sources.

If it is determined by the copyright management server 120 that the sound source is serviceable, the service provider 110 determines whether the sound source determined to be the serviceable sound source has been registered with the service server (not shown). Here, the service server may be a download service or a streaming service.

If the service capable sound source is not registered in the service server, the service provider 110 may register it in the service server and enable the service.

Alternatively, the service provider 110 notifies the copyright management server 120 of whether to register a service of a service enabled sound source, and the same sound source may manage a service registration request later.

According to FIG. 4A, the service table may include a DISCID indicating a unique ID of each audio CD and an ISRIGISTER item indicating whether a service is registered for each audio CD. In some cases, the service table may include whether to register a service for each sound source included in each audio CD. Here, the DISCID and ISRIGISTER items are defined as a char type, which is used to represent static data. DISCID is a unique ID of audio CD. Since it is set to 12 digits, the char type can be used. Since the ISRIGISTER item can be represented by 1 digit of Y or N, char type can be used.

In addition, the determination unit 111 changes the ISRIGISTER item to Y when the audio CD, which is a service non-registration state (ISRIGISTER item: N), is registered with the service server to enable the download or streaming service through an encoding process. You can update the information.

The service table in the present embodiment is just an example, and may be changed in various forms for checking whether a service is registered for each audio CD or sound source.

The encoding unit 112 performs an encoding operation on the unregistered sound source according to the determination result of the determination unit 111. The encoding unit 112 includes an MP3 encoder, a buffer, and the like, and extracts a sound source from an audio CD through the MP3 encoder and stores the sound source in a buffer and transmits it to a service server such as a download service providing server or a streaming service providing server. . For example, the encoding unit 112 converts an audio CD track (cda file) into a wav file and then compresses and converts the wav file into mp3 to transmit the compressed sound source in the mp3 form to the service server. have. Hereinafter, since the process of compressing the cda file into the mp3 file is a known technology, further description thereof will be omitted.

In addition, the encoding unit 112 performs encoding by applying a preset bitrate, frequency, and layer when encoding the unregistered sound source. By encoding by applying a constant attribute value, it is possible to provide a sound source of the same quality. Here, the attribute value is a value required when the analog sound source is encoded and digitized (mp3, wma, ogg), and means bitrate, frequency, and layer.

4B is a diagram illustrating an example of encoding criteria that may be applied when encoding.

According to FIG. 4B, for example, the frequency may be set to 44,100 KHz, the layer may be set to MPEG 1.0 Layer 3, and the bit rate may be set to 192 kbps. In addition, such encoding criteria may be changed / set by an administrator of the service provider 110 as necessary.

In addition, the encoding unit 112 may encode only the entire track or a part of the track of the audio CD according to the determination result of the determination unit 111.

The notification unit 113 may notify the copyright management server 120 of the determination result of the determination unit 111. That is, it is possible to notify the copyright management server 120 whether the service registration of each audio CD and the service registration of each sound source.

The notification unit 113 may notify the copyright management server 120 that the service capable sound source is not registered or registered in the service server by the determination unit 111, and may block a service registration request of the same audio CD in advance. In particular, it is notified that all tracks or some tracks of an audio CD are registered or unregistered, so that when only some tracks are registered with the service server, the copyright management server 120 may later perform a service registration request of the same audio CD. Can be.

Hereinafter, a detailed configuration of the copyright management server 120 will be described.

The storage unit 121 stores the copyright information for each DISCID. That is, the storage unit 121 may store information on whether each of the audio CDs can be serviced according to copyright or not and whether or not all tracks / some tracks are available for each DISCID.

5A illustrates an example of a contents table indicating whether service is available.

According to FIG. 5A, the contents table includes a CPCODE indicating a unique ID of a company that owns a sound source, a DISCID indicating a unique ID of an audio CD, a DISCNAME indicating a title of an audio CD, an AVAILABLETRACK indicating a serviceable track, and a SERVICE indicating whether service is possible. It may include an ALLSERVICE item indicating whether all songs are available. Where int is used for numeric data, char for static data, and varchar for variable data.

For example, since the DISCID item is set to 12 digits, and the SERVICE item and ALLSERVICE item are also represented by one digit of Y or N, the char type is used, and the item to which variable data is applied, such as the DISCNAME item and the AVAILABLETRACK item, is used. varchar type is available.

5B is a diagram illustrating an example of a CP table indicating information of a contents provider (CP).

According to FIG. 5B, the CP table includes a CPCODE, which is a unique ID of a company that owns a sound source, and a CPNAME, which is an actual company name.

7 is a flowchart illustrating a content providing method according to an embodiment of the present invention.

According to the content providing method of FIG. 7, the copyright management server determines whether the service is available according to the existence of copyright for the content provided from the source (S710). For example, when the content is sound source data provided by the audio CD router, it is possible to determine not only whether each audio CD is serviceable, but also whether or not the service is available for all or some tracks of the audio CD. In addition, when only some tracks of the audio CD are available for service, some tracks that can be serviced can be specified and determined.

If it is determined in step S710 that the service for the content is possible, the service provider requests a service registration for the serviceable content (S720).

8 is a flowchart illustrating a content providing method according to FIG. 7 in detail. For convenience of description, in FIG. 8, a case where the content is sound source data provided from an audio CD will be described as an example. According to the content providing method of FIG. 8, when an audio CD is inserted into a CD-ROM (S810), the copyright management server determines whether a service of a sound source of the inserted audio CD is possible (S820). In this case, it is possible to determine whether or not the service of all or part of the sound source of the audio CD can be determined using the data on which service information is stored using the DISCID of the audio CD as an identifier.

If it is determined that the service for the sound source of the inserted audio CD is possible (S820: Y), the service provider requests a service registration for the sound source of the audio CD (S840).

The service provider requesting service registration for the audio CD checks whether the sound source of the audio CD is registered in the service server (S840). In this case, the service server may specifically be a download service providing server or a streaming service providing server.

As a result of checking in step S840, if the sound source of the audio CD is registered in the service server (S840: Y), it notifies the copyright management server whether or not it is registered (S850). In this case, the copyright management server may be notified whether the audio CD is registered with the service, whether the entire sound source or a part of the sound is registered with the service, whether or not the service is registered for each of the sound sources included in the audio CD.

If the sound source of the audio CD is not registered in the service server as a result of step S840 (S840: N), the service provider performs encoding by applying a preset encoding attribute value Bitrate, Frequency, and Layer to the sound source of the audio CD. (S860). Thereafter, the sound source encoded in step S860 is registered with the service server (S870). Subsequently, the copyright management server may be notified whether or not the service is registered (S850). In this case, it is possible to notify whether or not all or some of the sound sources of the audio CD have been registered for service, and if some of the sound sources have been registered for service, information on the registered sound sources.

Accordingly, it is possible to efficiently and quickly provide a service for the sound source of the audio CD.

As described above, according to the present invention, it is possible to provide a service efficiently and quickly through copyright management of contents. In addition, it is possible to provide an improved quality of service through the standard management of the content used in the service. As a result, the convenience of the user is greatly increased according to the present invention.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the above-described specific embodiment, the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
