In addition, the IPTV hosting server 200 includes a subscriber information database 250 that stores contract information, profile, broadcast content, broadcast schedule, etc. for each subscriber.

In the IPTV hosting server 200, the customer management system 210 receives contract information of contracted subscribers and stores contract information for each subscriber in the subscriber information database 250. When the contract information of the new subscriber is stored in the subscriber information database 250, the contract information generation unit 211 generates the corresponding contract information with reference to the subscriber information database 250 and transmits the contract information to the profile management system 220. The management system 220 generates a profile and encrypts and stores the profile in the subscriber information database 250, thereby setting the bandwidth of broadcast data for the content of the subscriber based on the profile. In addition, the content management system 230 registers the broadcast content of the subscriber registered from the subscriber system 100 below the bandwidth set according to the profile in the profile management system 220 and registers the broadcast content (the live data as the broadcast data in real time). Registered content for the user) may be stored in the subscriber information database 250 for storage management. The transmission system 240 receives broadcast data for real-time live broadcasting from the subscriber system 100 and transmits the broadcast data to the IPTV viewing terminal 300, and also provides broadcast data for real-time file live broadcasting requested by the IPTV viewing terminal 300. The subscriber information database 250 may search and transmit the information to the IPTV viewing terminal 300.

In the subscriber system 100, the encoding system 110 encodes a video signal received from a cam coater or the like into broadcast data for real-time live broadcasting at a bandwidth less than or equal to the bandwidth set according to the profile in the profile management system 220. By transmitting in real time to the transmission system 240 to enable the IPTV viewing terminal 300 to output the broadcast data for real-time live broadcasting. The broadcast management system 120 creates a broadcast schedule and transmits the content to be used for broadcasting to the IPTV hosting server 200 so that the content according to the subscriber's broadcast schedule can be stored and managed in the subscriber information database 250 as shown in FIG. do.

Hereinafter, operations of the content management system 230 and the subscriber system 100 will be described in detail with reference to FIGS. 3 to 5.

3 is a flow chart for explaining the operation of the profile management system 220 of the IPTV hosting server 200 according to an embodiment of the present invention.

First, the contract information receiver 221 receives customer contract information from the customer management system 210 (S221). When a new customer is generated and contract information newly registered and stored in the subscriber information database 250, for example, as shown in FIG. 6, there is a contracted number of channels, bandwidth for each channel, usage period, number of allowed terminals, and the like. The contract information generation unit 211 of the customer management system 210 refers to the subscriber information database 250 and provides information on the subscriber, such as the number of channels, bandwidth (or bit rate) information for each subscriber, usage period, and number of allowed terminals. Generates the contract information, including the transmission to the contract information receiving unit 221. In addition, the contract information generator 211 may generate the changed contract information of the subscriber and transmit the changed contract information to the contract information receiver 221 even when the contract information of the existing subscriber is changed.

Here, the new customer registered through the customer management system 210 may be a plurality of corporate customers for providing IPTV in-house broadcasting, or in some cases, may be individual customers. The customer management system 210 manages contract information for each subscriber, which is registered and stored in the subscriber information database 250 as described above, where the number of contracted channels managed is paid by the subscriber at the time of registration and contracted. The number of channels and the bandwidth for each channel are allowed bandwidths for each channel when there are a plurality of channels contracted with each subscriber, and may be managed in units of Mbps, for example, 10, 20..Mbps. The usage period of each subscriber's contract information is an allowable period for providing contracted broadcasting data at a predetermined cost. The number of allowed terminals may be the number of allowed terminals limiting the number of connection of the IPTV viewing terminal 300 in consideration of the resources of the hosting server 200.

When the contract information receiver 221 receives the contract information of the subscriber as described above, the profile generator 222 is a profile (profile) for the subscriber including the bandwidth information and usage period for each channel based on the received contract information as described above. ) May be generated (S222). Here, the profile generator 222 sets the bandwidth of the broadcast data for the content of the subscriber according to the profile including the bandwidth information and the usage period for each channel, thereby real-time file broadcasting as well as real-time live broadcasting of the video provided by the subscriber. In addition, it is limited to perform broadcasting within the bandwidth within the licensed usage period.

Accordingly, the encryption processing unit 223 encrypts the profile generated by the profile generation unit 222 (S223), and the profile storage unit 224 may store the encrypted profile of the subscriber in the subscriber information database 250. (S224). Herein, the encryption processing unit 223 encrypts the DRM (Digital Right Management) so that the subscriber side cannot arbitrarily modify after receiving the profile, and the operator side of the IPTV hosting server 200 uses the encryption key used for DRM encryption. It is possible to change the profile.

4 is a flowchart illustrating an operation of the encoding system 110 of the subscriber system 100 according to an embodiment of the present invention.

In order to perform real-time live broadcasting on the subscriber side, first, the encoding system 110 of the subscriber system 100 checks whether a profile previously received exists (S111). If the encoding system 110 previously transmitted broadcast data through the encoding processing unit 112, there may be information that the profile manager 111 has already received and stored the profile.

If the profile previously received by the encoding system 110 does not exist, the profile manager 111 requests the corresponding profile from the IPTV hosting server 200 (S114), and accordingly the IPTV hosting server 200 The profile generator 222 may receive the corresponding profile searched and transmitted from the subscriber information database 250 and store it in a predetermined storage means (S115). In this case, the profile generated by the profile generator 222 to search and transmit in the subscriber information database 250 may be an encrypted profile, which may be decrypted and used using a predetermined encryption key managed by the profile manager 111. .

Accordingly, when a profile previously received by the encoding system 110 already exists or when a new profile is received from the IPTV hosting server 200 as described above, the subscriber side selects the profile through a user interface screen or the like. In order to perform the real time live broadcasting, the following procedure may be performed (S112). When the profile selection is completed, the profile manager 111 may perform a verification process that the valid period of the profile is valid (S113). If the profile is not valid at this time, the IPTV hosting server as in steps S114 and S115 above. The user profile 200 may re-request the received profile.

If the profile manager 111 verifies that the profile is valid and determines that it is valid, the profile manager 111 sets a broadcast bandwidth according to the profile (S116). At this time, the profile management unit 111 can be set only below the specified bandwidth according to the profile.

Accordingly, the encoding processor 112 encodes a video signal including video and audio signals received from a photographing means such as a cam coater into broadcast data (or packets) for real-time live broadcasting in accordance with the broadcast bandwidth set as described above ( S117), the encoded data is transmitted in real time to the transmission system 240 of the IPTV hosting server 200 (S118). Here, the encoding method may be a predetermined data compression method such as MPEG. The transmission system 240 may transmit broadcast data (data for real time live broadcasting) received from the encoding processing unit 112 to the IPTV viewing terminal 300 in a multicast manner, and thus the user may transmit the broadcasting data through the IPTV viewing terminal 300. The channel of the broadcast data for the real time live broadcast can be selected and viewed.

5 is a flowchart illustrating an operation of the content management system 230 of the IPTV hosting server 200 according to an embodiment of the present invention.

In order to perform live file live broadcasting through broadcasting such as promotion and advertisement using a pre-produced video file at the subscriber side, first, the broadcast management system 120 of the subscriber system 100 includes content for use in broadcasting. After extracting from the database 121 and transmitting to the IPTV hosting server 200 to complete the registration process, a broadcast schedule may be generated using the corresponding content.

Accordingly, when the content registration unit 232 of the content management system 230 receives the corresponding content (S231), the bandwidth of the corresponding content is checked, and the contract information receiving unit 231 receives the contract information from the profile management system 220. (Or profile) check (S232). The content registration unit 232 verifies whether the bandwidth of the content received from the broadcast management system 120 is an allowable bandwidth based on the received contract information (or profile) (S233).

Accordingly, when the bandwidth of the content received from the broadcast management system 120 is content less than or equal to the bandwidth registered for the subscriber, the encryption processing unit 233 encrypts the content received from the broadcast management system 120, The content storage unit 234 may store the encrypted corresponding content as the broadcast content of the corresponding subscriber in the subscriber information database 250 as shown in FIG. 6 (S234). As such, the registered content stored in the subscriber information database 250 is the content for real-time file live broadcasting as broadcast data. Here, the encryption processing unit 233 may encrypt the content (DRM). In addition, when the bandwidth of the content received from the broadcast management system 120 is a content larger than the bandwidth registered for the subscriber, the content registration unit 232 transmits a content registration impossible message to the broadcast management system of the subscriber system 100 ( 120 may be transmitted (S235).

As such, the content stored in the subscriber information database 250 by the content registration unit 232 may be transmitted through the transmission system 240 to the channel of the subscriber at the corresponding time period according to the broadcasting schedule of the subscriber, and the IPTV viewing terminal. In operation 300, broadcast data for the corresponding content may be received by selecting a channel of the subscriber, and the broadcast data for the content may be decoded and decoded using a predetermined encryption key and output through the audio and video system.

As described above, in the IPTV broadcasting hosting system according to the present invention, an encoding process for real-time live broadcasting occurs on the subscriber side based on the profile, and the broadcasting server 200 transmits the broadcast data. Means may be provided for limiting the bandwidth available for broadcasting. Such a limitation of bandwidth available for broadcasting for each subscriber may provide a means for limiting bandwidth not only for real-time live broadcasting but also for live file live broadcasting using a video file.
