In addition, in certain cases, there is also a term arbitrarily selected by the applicant, in which case the meaning will be described in detail in the description of the invention. Therefore, it is intended that the terms used in the present invention should be defined based on the meanings of the terms and the general contents of the present invention rather than the names of the simple terms.

An Internet Protocol TV (IPTV) system, which is an example of a system that can provide various contents using the Internet network, can be largely divided into a server, a network, and a receiver.

The servers of the IPTV are servers that perform various functions such as service discovery and selection server, streaming server, contents guide information server, customer information server, and payment information server. It can be configured as.

Among the servers, the streaming server transmits video data encoded in the stored Moving Picture Experts Group (MPEG) 2, MPEG4, etc. to the user through a network. As a protocol for the transmission, a Real-Time Transport Protocol (RTP), a RTP Control Protocol (RTP), or the like may be used.

In case of using Real-Time Streaming Protocol (RTSP), video stream playback can be controlled to some extent through a function called network trick play such as pause, replay, and stop. . The protocols are one example and other real time transmission protocols may be used depending on the implementation.

The content guide information server is a server that provides information on the various contents provided. The content guide information is information corresponding to electronic program guide (EPG) information and includes various information about content. The content guide information server stores content guide information data, and provides the stored data to the receiver.

The information server related to service discovery and selection among the servers provides the receiver with access information and playback information for servers providing various content services such as broadcasting, contents on demand (COD), and games.

The network system consists of an internet based network and gateways. The Internet-based network may use various types of networks such as an optical cable network, a coaxial cable network, a fiber to the home (FTTH), a telephone network, a wireless network, and the like based on IP. In addition to general data transfer, the gateway may perform multicast group management and quality of service (QoS) management using protocols such as Internet Group Management Protocol (IGMP).

A receiver of an IPTV is a receiver capable of receiving data transmitted through an internet network and providing the same to a user. The receiver includes an IPTV settop, a homenet gateway, an IPTV embedded TV, and the like.

In the case of a hybrid IPTV system, various types of contents of the Internet as well as various types of existing broadcasting contents may be provided. That is, the user can provide various broadcasting contents such as terrestrial broadcasting, cable broadcasting, satellite broadcasting, personal broadcasting, various internet video contents, data contents other than video, and the like. The contents may be provided in real time or may be provided on demand.

1 is a diagram schematically showing an IPTV system according to an embodiment of the present invention.

In terms of providing a content service, the IPTV system may be divided into a content provider (CP), a service provider (SP), a network provider (NP), and a user.

The content provider produces and provides various contents. As shown in FIG. 1, the content provider includes a terrestrial broadcaster, a cable SO, or a MSO, a satellite broadcaster, and an internet broadcaster. (Internet broadcaster) and the like.

The service provider provides a service package of contents provided by the content provider. For example, the service provider of FIG. 1 packages a first terrestrial broadcast, a second terrestrial broadcast, a cable MSO, satellite broadcast, various Internet broadcasts, and provides the same to a user.

The service provider provides a service to the user side using a unicast or multicast scheme. 2A and 2B are diagrams schematically showing multicast and unicast schemes, respectively. The unicast method is a method of transmitting data 1: 1 between one sender and one receiver. For example, in the unicast scheme, when a receiver requests data from a server, the server transmits data to the receiver according to the request. Multicasting is a method of transmitting data to a plurality of recipients of a specific group. For example, the server can send data to multiple pre-registered receivers at once. The Internet Group Management Protocol (IGMP) protocol may be used for the multicast registration.

The network provider provides a network for providing the service to the user. The user may build a home network end user (HNED) to receive the service.

Conditional access, content protection, or the like may be used as a means for protecting the content transmitted from the IPTV system. As one example for the above-mentioned restriction reception or content protection, a method such as a cable card or a downloadable conditional access system (DCAS) may be used.

3 is a diagram illustrating a hierarchical structure for broadcasting a Content Download Service (CDS) of IPTV.

Referring to FIG. 3, the service provider delivers data contents for CDS to an IPTV receiver using a transport protocol. The delivered data content for CDS is stored in the storage of IPTV. The stored data contents for CDS can be executed at the request of the user or the like. The transport protocol may be a File Delivery over Unidi-rectional Transport (FLUTE) mounted on ALC / LCT over IP / UDP, and may include DVB-STP, DVB data / object carousel, File Transfer Protocol (FTP), HTTP ( hypertext transfer protocol), and the above-described protocol may be used as another example.

When FLUTE is used as the transport protocol, the presence or absence of a CDS service may be known to an IPTV receiver through service discovery and selection (SD & S), and the details of the content may include metadata in a TV Anytime format. You can find it through:

Data contents for CDS may include various types of contents and applications such as A / V contents, data contents, and game contents.

On the other hand, while the need to download and execute these various types of content on the IPTV, the application add-on (Add-on) function that can provide various types of content to download, execute and provide We propose an IPTV configuration.

FIG. 4 illustrates a hierarchical structure of an application add-on function for downloading, executing, and providing various types of contents according to an embodiment of the present invention.

Referring to FIG. 4, the IPTV according to an embodiment of the present invention downloads, executes, and expands content in a process separate from execution of host software (for example, software, applications, etc., which is executed in an existing DTV).

In this case, the content added (on) independently of the execution of the host software may be broadband service content, IPTV content, and the like, and the device driver and the middleware may be used by the host software and the additional application on the same basis.

If the add-on function is implemented, content (for example, an add-on application) to be added is driven by a process separate from the host software, thereby enabling simultaneous execution of a plurality of contents, and different from the host software. Applications based on operating systems (eg Linux) also make it easy to add and run IPTV.

5 is a diagram illustrating a configuration for implementing an application add-on function in IPTV according to an embodiment of the present invention.

Referring to FIG. 5, the IPTV includes an add-on system manager and an add-on host for implementing the add-on function. The add-on system manager performs overall management of installing, running, managing, and deleting add-on applications.

The application browser may output the downloaded content to the display unit, and when the user interface manager receives selection of one or more of the downloaded contents from the user, the application controller executes the selected input content according to the control command of the add-on host. .

Add-on hosts are configurations that must be added to IPTV to support running Add-on System Manager, and can include host agents and open API hosts. For example, the add-on host may be an operating system for controlling reception and execution of content separately from performing output of a broadcast signal in addition to host software of IPTV.

The host agent sends and receives status information of the host software of the IPTV and key events of external input devices (remote control, etc.).

The open API host executes the open API call of the add-on application and receives the result. The add-on application sends an open API in response to a call of an open API host included in the host agent. At this time, the open API may be provided in the form of a shared library, and the add-on application may register itself with the add-on manager through the open API and use a function provided by the host software.

As described above, since the add-on system manager operates separately from other functions of the IPTV, even if a plurality of content executions are selected, the add-on system manager can execute all the selected contents.

On the other hand, since the content output on the display screen by the operation of the add-on host and the add-on system manager is output in the form of OSD, it has a different form from the video signals of the prior art, it is proposed an IPTV system for recording such content in the digital broadcast receiver do.
