1 is a diagram illustrating a network configuration to which a content delivery control apparatus according to an embodiment of the present invention is applied, and FIG. 2 is a view illustrating an example of a content delivery control method by a content delivery control apparatus according to an embodiment of the present invention. to be.

Referring to FIG. 1, the smart TV 10 is equipped with an operating system (OS) such as a personal computer (PC) or a smart phone to connect the Internet to a TV terminal, thereby providing Internet-based content and services in addition to the existing broadcast content. . The smart TV 10 receives the broadcast content from the broadcast transmission server 20 through the broadcast network 1 and provides the content through the TV screen, and accesses the Internet to receive the content through streaming to provide the content through the TV screen.

The broadcast transmission server 20 is a device for transmitting broadcast content to the smart TV 10 through the broadcast network 1. The broadcasting network 1 may be a terrestrial network, a satellite network, a cable network, an IPTV (nternet protocol television) network, or the like. Hereinafter, the broadcasting content received through the broadcasting network 1 or the video, audio and data contents received through the Internet will be referred to as 'content'.

The smart TV 10 may include a content transmission control device 100 for transmitting content provided through a TV screen to at least one user terminal 50a to 50c. Here, the users of the at least one user terminal 50a to 50c may be the same or different.

The content transmission control device 100 may exist independently as a device separate from the smart TV 10.

The content transmission control apparatus 100 may provide content to at least one user terminal 50a to 50d through a place-shift through the smart TV 10.

Specifically, the content transmission control device 100 requests the user profile information of the user terminals 50a to 50c from the user profile server 30 to the user profile server 30 and receives the received user profile information from the user profile server 30. A request from the 40 to guarantee the quality of service (QoS) of the corresponding content may guarantee the service quality of the corresponding content. Here, the user profile server 30 manages user profile information, and the ISP control server 40 performs resource reservation for QoS guarantee of content. The user profile information may include specification information of the user terminal, QoS information, terminal preference information of the user, and the like.

The content transmission control apparatus 100 may simultaneously transmit content corresponding to a service desired by each user to at least one user terminal 50a to 50c. In this case, although the same content may be transmitted to the user terminals 50a to 50c, different contents may be transmitted.

The content transmission control apparatus 100 may convert the content according to the user profile information of the user terminals 50a to 50c and transmit the content to the user terminals 50a to 50c, and to match the user profile information of the user terminals 50a to 50c. It can also guarantee the quality of service of the content.

When the user moves and the access network of the user terminals 50a to 50c is changed, the content transmission control apparatus 100 may provide a connection to the changed access network by recognizing a wireless interface to which the user terminals 50a to 50c are connectable.

In addition, the content transmission control device 100 recognizes this when the user moves the location from the user terminal (for example, 50a) to another user terminal 50d in the home, and attempts to connect with the user terminal 50d. The content is transmitted to the user terminal 50d. In this case, the user terminals 50a and 50d recognize the user entering or leaving the area managed by the user and transmit the location information of the user to the content transmission control apparatus 100 so as to transmit the user's location information to the content transmission control apparatus 100. The location movement may be known, and through the other method, the content transmission control apparatus 100 may also know the position movement of the user.

If the content transmission control apparatus 100 determines that the content transmission to the user terminal 50d is stable after transmitting the content to both user terminals 50a and 50d, the content transmission control apparatus 100 may release the connection with the user terminal 50a.

Meanwhile, when there are a plurality of user terminals at a location to which the user has moved, the content transmission control apparatus 100 may select one user terminal to transmit content according to a user terminal preference registered in advance. Alternatively, the content transmission control apparatus 100 may select a user terminal located closest to the user as a terminal to transmit the content.

The content transmission control apparatus 100 may transmit the differentiated content through at least one connection of each of the user terminals 50a to 50c according to the characteristics of the service requested by the user.

The user terminals 50a to 50d are multi-mode terminals including a plurality of network interfaces (hereinafter referred to as "connections") to be able to connect to a plurality of different networks, through a parent network. It may be any mobile or portable wireless communication terminal capable of exchanging data with another terminal in a wireless form with network equipment or its parent network. The user terminals 50a to 50d are, for example, on the one hand a General Packet Radio Services (GPRS) / Enhanced Data rates for GSM Evolution (EDGE) and / or a Universal Mobile Telecommunications System (UMTS) communication network and wireless on the other hand. It can connect to a plurality of different wireless access networks, such as LAN and / or Wi-Fi and / or broadband wireless networks.

In addition, when the backbone network 2 to which the wireless access networks such as the fixed network 3 and the mobile network 4 are combined is an internet protocol (IP) network, the user terminals 50a to 50d may be connected to servers of the IP network. In order to exchange information, it is possible to connect to network equipment, including external application servers (or Internet sites), coupled to the IP network via a wireless access network. The external application server may be, for example, a dedicated server for transmitting music or video.

The user terminals 50a to 50d may include an internal application, for example, a web browser, in which a user may initiate a service session using an external application to download data managed by an external application server.

A service session may be composed of different types of transactions defined by certain characteristics and associated with service semantics. Service semantics define the meaning of any given transaction in the associated application. For example, a transaction may include retrieving an internet site or any page of the internet site, requesting the transmission of a film, or requesting a temporary or permanent stop of a film.

Each transaction coming from an internal or external requesting application is specified by the requesting application through a transport-level connection established between the equipment on which the requesting and requested application is installed, for example, a multi-mode terminal and an application server. A procedure for transmitting to the requested application.

Successive transactions of the same type or different types during the same service session do not necessarily require the use of the same fast bit rate or ultra fast bit rate connections. For example, there is no need to use an ultrafast bit rate connection to transmit a request to temporarily or permanently stop the transmission of video data, but the video data transmission itself may require an ultrafast bit rate connection. Therefore, the content transmission control apparatus 100 may differentiate and transmit content for each connection of the user terminals 50a to 50d according to the characteristics of the service desired by the user.

Similarly, the content transfer control device 100 may connect at a high bit rate rather than immediately start a service session using a low bit rate connection resulting in low quality playback under any circumstances, depending on the characteristics of the service desired by the user. You can also wait for a while while the connection is available. For example, if a UMTS / WiFi bimode terminal is moved to an area with WiFi hot spots, sending video data at a high bit rate through the WiFi connection network whenever a WiFi hot spot is reached. I can wait for you.

As such, the content transmission control apparatus 100 according to an exemplary embodiment of the present invention may respond to the service requests of the plurality of user terminals 50a to 50c to the user terminals 50a to 50c of the respective user terminals 50a to 50c. The content corresponding to the service is transmitted in accordance with the user profile information and the characteristics of the service. For example, when the user 1 wants the content of the channel provided by the smart TV 10 through the user terminal 50a, the content transmission control apparatus 100 may display the content of the channel provided by the smart TV 10. The content is converted according to the user profile information of the terminal 50a and transmitted through at least one connection of the user terminal 50a. In this case, when the user 1 moves and moves the position to the user terminal 50d, the content transmission control apparatus 100 attempts to connect with the user terminal 50d so that the user 1 can be provided with content without interruption. The content is transmitted to the user terminal 50d.

In addition, when the user 2 and the user 3 requests a channel service different from the channel service provided by the smart TV 10, the content transmission control device 100 is connected to the user terminal (50b, 50c) of the user 2 and user 3; The service request may be processed to transmit contents of the channel service requested by the user 2 and the user 3 through at least one connection of the user terminals 50b and 50c.
