For example, the content providing management unit 12 transmits the address information to an NPVR stream server among a plurality of stream servers when the content is on-demand content, and the address information to a stream server in charge of real-time content when the content is real-time content. Can be transmitted. However, according to another embodiment of the present invention, the content providing management unit 12 determines whether the content is on-demand content or real-time content, and delivers the result of the determination to the integrated stream server including all the functions of the plurality of stream servers. In addition, the content may be transmitted to the first terminal according to the determination result transmitted from the integrated stream server.

In general, NPVR may be an example of a stream server that stores content on demand remotely through a network and provides the stored content to the terminal. In addition, real-time content refers to content provided in real time for a predetermined time (for example, broadcast content provided by a broadcasting system), and on-demand content is content provided at a time desired by a user (or viewer) without time restriction. It may mean. In addition, one example of such real-time content may include a broadcast data stream provided to the broadcasting system, and one example of the on-demand content may include movie data that can be purchased and educational education video that can be purchased.

When the content requested from the first terminal is real-time content, the content provision management unit 12 may deliver a message requesting the content received from the first terminal to an EPG server that manages scrap information about the real-time content. . In this case, the EPI server will instead process the operation performed by the scrap information management server 10. For example, when the EPG server receives the message requesting the content delivered from the content provision management unit 12, the EPG server provides the content list information to the first terminal, and the first terminal selects the predetermined content from the content list information The stream server 30 can be instructed that the stream server 30 transmit the selected content to the first terminal by transmitting the address information in which the selected content is stored to the stream server 30. [

The stream server 30 transmits the content to the first terminal. In this case, the content may refer to content that the first terminal requests from the content providing management unit 12. The stream server 30 may provide the stream of the content to the first terminal by using the address information of the location where the content is stored. In detail, the stream server 30 may obtain the content from the location where the content is stored, convert the obtained content into a stream data form transmitted through a network, and provide the same to the first terminal. At this time, the stream server 30 may determine the type of the stream data based on the terminal profile information of the first terminal. For example, the stream server 30 may convert the content acquired based on the terminal profile information of the first terminal into a stream data format based on an IP protocol and provide the same to the first terminal. In addition, as described above, the address information may be provided to the stream server 30 from the content providing management unit 12 or the first terminal, and the content may be stored in a predetermined storage space or scrap inside the scrap information management server 10. It may be stored in a storage space outside the information management server 10, in a storage space inside another terminal that is different from the first terminal, or in the stream server 30.

As the content is transmitted from the location where the content is stored to the first terminal, the scrap information manager 13 receives scrap information of scrap content scraped from the content from the first terminal. At this time, as described above, the content may be obtained from a location stored by the stream server 30 and transmitted to the first terminal.

The first terminal reproduces the content based on the stream data of the content received from the stream server 30, and generates scrap information of the scrap content scraped from the reproduced content. At this time, it means a part of the content of the scrap content, such scrap content can be divided as the upper limit and the lower limit of time or the order of the frame. In general, the scrap content is generated based on a signal input from the user interface of the first terminal while the content is being played on the first terminal. In this case, the input signal collectively refers to signals input for scraping of content from the user. For example, the input signal may mean time information or frame information that defines a part of the content that was being played. It may also mean a signal for requesting to stop a frame (or still image) of the content. As described above, this user interface may be a graphical user interface or may be a touch screen panel.

Generally, the scrap information includes at least one of identification information of scrap content and comment information of scrap content. At this time, the identification information of the scrap content means information for identifying the scrap content in comparison with the content. For example, the identification information may include title information of the scrap content and index information (for example, start of playback of the scrap content). Information indicating a time and reproduction end time or a plurality of frame information for specifying scrap content). Also, an example of comment information of scrap content includes information written by a user, such as a title, description, rating, and a tag of scrap content.

One example of such an application may include a scrap player for playing content and generating scrap content.

The first terminal transmits a predetermined message for scraping the content being played back to the stream server 30. For example, the first terminal transmits a message for initiating trick play with respect to the content being played to the stream server 30, and a section to be scraped from the content played from the user based on the started trick play. You can receive the time and the end time. In this case, the trick play may mean a play mode in which a change in the playback speed, playback direction, or playback time of an image is distinguished from normal play. In addition, the first terminal provides a user with control rights corresponding to the trick play. For example, the first terminal may pause or rewind the content in response to a command input from the user interface while the content is being played. To this end, the stream server 30 provides a stream corresponding to the trick play to the first terminal. In addition, the first terminal may perform an operation corresponding to a play command, that is, a general play command, compared to a trick play command. For example, the stream server 30 stops the stream transmission of the content in response to the trick play command received from the first terminal and provides a partial stream of the content corresponding to the trick play command to the first terminal, and the first terminal. The stream transmission of the interrupted content can be resumed in response to the play command received from the.
