FIG. 6 is a diagram referred to explain a hybrid TV, and FIG. 7 is a diagram referred to explain an advanced EPG.

A hybrid TV can use contents that are streamed through a broadcast network or a broadband network using a video display device.

In addition, a hybrid TV may be an image display device capable of transmitting and receiving signals according to hybrid standards of respective countries. For example, it may be a video display device conforming to the European HbbTV (Hybrid Broadcast Broadband TV) standard, the Japanese Hybridcast, and the Korean OHTV (Open Hybrid TV) standard.

FIG. 6 illustrates a receiver structure according to an OHTV (Open Hybrid TV) standard. Hereinafter, a hybrid TV will be described centering on OHTV (Open Hybrid TV), but the present invention is not limited thereto.

Referring to FIG. 6, the CE-HTML standard is a standardized technology that enables a web-based UI to be used in a home appliance, and includes XHTML (eXtensible Hyper Text Markup Language), Cascading Style Sheet (CSS), Document Object Model (DOM) (AJAX) and so on

The browser API is necessary for a web page type application to use receiver internal functions such as video receiving and playback, storage, and on-air broadcast display.

The AV object is used for content reproduction in the VOD service, the download object is used for storing and managing the moving picture in the receiver, and the TV control object is used for displaying and managing the broadcast stream in the application.

Various metadata needs to be utilized in order to manage contents in a receiver and to combine services among various providers to provide new information to a user.

For example, a contents access descriptor (CAD) includes information such as a content ID, a URL, an expiration date, and a title. The content ID standard is based on Universal Content Identifier (UCI), which each service provider can design to be compatible with the existing identification scheme. MPD (Media Presentation Descriptor) is metadata used in an adaptive streaming method, and provides information necessary for a receiver to request an appropriate bit rate of content.

The transmission of the signal is transmitted through broadcasting and the Internet using the non-real time (NRT) of the ATSC and the HTTP protocol.

Transmission using terrestrial broadcasting network conforms to NRT standard of ATSC 2.0, and contents are transmitted to several IP addresses using DSM-CC method, and IP packets are transmitted according to FLUTE protocol. NRT is used for transmitting contents of push VOD service, preview for advanced EPG service, and data such as web page using a broadcasting network.

The OHTV service platform transmits real-time digital broadcasting and Push VOD data through a broadcasting network, and can transmit VOD data, metadata and HTML-type applications through the Internet.

The OHTV service is a channel bound service that is executed depending on a broadcast channel. When tuning the RF broadcast channel 710 as shown in FIG. 7, the OHTV service can receive URL information through signaling information included in broadcast data.

On the other hand, when the user inputs a predetermined command, for example, when the red color key button is pressed, IP broadcast contents can be used. In this case, the video display device can display information related to the IP broadcast contents, UIs 731 and 732, and the like on the RF broadcast video 720 or can transfer them to a separate screen. In addition, the video display device can transmit and receive IP broadcast contents in the form of HTML through the Internet using the received URL information.

An Advanced Electronic Program Guide (EPG) may include menus that allow a user to easily request IP content such as VOD based on detailed program information as well as program information.

For example, the user can check detailed program information of the currently broadcasted RF channel such as program genre, performer, and various additional data services such as OST, thumbnail image, and trailer through the advanced electronic program guide.

8 is a flowchart showing a conventional channel management method.

In the case of RF broadcasting, tuning is performed on a predetermined channel (S811), and the RF signal is received (S812), and the advanced EPG information is parsed from the received RF signal to store the channel number (S813)

On the other hand, in the case of IP broadcasting, broadcast channel data of the server is received (S821), and a multicast signal is received according to the channel number to use the service (S822)

In case of the existing RF broadcasting, the channel number of the EPG information included in the RF signal is used instead of the physical channel number. In the case of IPTV, the channel information is basically received from the IPTV company server and assigned to each channel list. Therefore, RF broadcasting and IP broadcasting are separately managed.

When a hybrid TV is used and an Advanced EPG is supported and an IP sub channel included in the EPG information is received, a channel number included in the EPG information of the RF signal is simply allocated There is a problem in that many channels are scattered and confused because they can not set a number adjacent to a channel of a related broadcasting company.

FIG. 9 is a flowchart illustrating an operation method of an image display apparatus according to an exemplary embodiment of the present invention, and FIGS. 10 and 11 are diagrams for explaining an operation method of an image display apparatus according to an exemplary embodiment of the present invention.

9, the image display apparatus tunes an RF broadcast channel (S910) and receives an RF signal from the tuned RF broadcast channel (S820)

Then, the image display apparatus parses the EPG information included in the RF signal and confirms the link information related to the IP (Internet Protocol) stream channel (S930)

In this case, the link information may be uniform resource locator (URL) information of the IP stream channel.

Meanwhile, according to an embodiment, the EPG information may include the link information. For example, an EIT (Event Information Table) of Program and System Information Protocol (PSIP) may include the link information.

Alternatively, the RF signal may include the EPG information and the link information. In this case, the EPG information data of the RF broadcast channel and the link information may be multiplexed on the RF signal and received.

On the other hand, if there is the link information (S940), the video display device 100 accesses the IP stream channel based on the link information (S950)

Here, the IP stream channel does not mean only a live streaming channel through the IP network. For example, a real-time streaming channel, a VOD service, a web site or a server of an IP broadcast service provider, and the like may be applicable.

In addition, the connection step S950 may include not only an operation of connecting to the service corresponding to the link information but also an operation of receiving or executing the IP broadcast contents via the Internet in HTML form using the received URL information, .

The image display apparatus 100 groups the IP stream channel numbers with the tuned RF broadcast channel numbers in operation S960. In other words, the image display apparatus 100 groups RF channels and IP subchannels into major channel numbers The same number or a similar number or an adjacent number can be assigned and managed. For example, when the terrestrial broadcast channel has a channel number of 6-1, the cable or IP channel of the corresponding terrestrial broadcast music, movie, drama, etc. is set to 6-2, 6-3, 6-4 And manage them by grouping them.

Meanwhile, EPG information can be parsed and analyzed on a digital channel after initial channel auto tuning is performed to determine the overall RF signal presence / absence per channel. In this case, it is determined whether or not the RF channel is coming in by IP streaming. If so, the channel number information in the EPG information of the RF channel may be read and the channel number may be assigned to the IP streaming.

Further, EPG information of the corresponding RF channel can be checked at a later time when a channel is switched to a predetermined RF channel, and channel number information can be updated and managed when there is a change.

Accordingly, it is possible to efficiently set and manage the RF broadcast channel and the IP broadcast channel number, thereby improving the usability of the user. When a broadcasting environment capable of simultaneously receiving RF and IP systems is established and a TV receiver is used, users who are already familiar with the RF signal environment can use the digital broadcasting channels You can easily adapt to.

On the other hand, upon reception of the user's advanced EPG information viewing command, an object representing the grouped IP stream channel can be displayed on the display.

In this case, the advanced EPG information viewing command may be an input for pressing a color key button, for example, a red color key button, provided in the remote controller.

That is, when the user calls advanced EPG information in any case, it is possible to display together objects representing channels grouped in addition to advanced EPG information.

On the other hand, advanced EPG information is not limited to text information such as a program name, a program execution order, and caption information provided by an image display apparatus, but may be an EPG service that can be controlled by a UI in the form of multimedia . Unlike the existing text-based EPG service, it contains various information and may include broadcast programs and link information. Accordingly, when multicast broadcast information such as IPTV is transmitted using the information, an RF channel and an IP channel can be mixed and used

In addition, an RF channel broadcast image corresponding to the RF signal may be displayed on a display, and an object representing the grouped IP stream channel may be displayed on the display.

That is, when a user watches a predetermined RF broadcast channel, objects representing channels grouped in the currently-viewed channel can be displayed together.

Meanwhile, the object representing the grouped IP stream channel may include at least one of an icon, a text, and a logo.

In addition, the object representing the grouped IP stream channel may be displayed in a color corresponding to a color key button provided in the remote controller. In this case, a color key button included in the remote control device can operate as a shortcut key for selecting a predetermined channel.

Referring to FIG. 10A, when a predetermined broadcast channel image 1010 is displayed and the broadcast channel has a sub-IP channel, information 1020 on the sub-IP channel may be displayed in one area of the screen have. The user can move the pointer 1050 to the remote controller 200 and select any one of the subchannels 1021, 1022, 1023, and 1024 for use.

Further, in the case where the information indicating the grouped IP stream channels is represented by hues 1031, 1032, 1033, and 1034 corresponding to the color key buttons provided in the remote controller, You can select the sub IP channel by pressing the color key button. In FIG. 10 (b), different colors are represented by diagonal lines in different directions for the sake of convenience.

The method may further include receiving an object view command indicating the grouped IP stream channel, and the object view command indicating the grouped IP stream channel may include a color key button It can be an input to press one.

Accordingly, upon receiving an input for selecting one of the color key buttons included in the remote control device, it is possible to switch to the IP stream channel corresponding to the selected color key button.

Alternatively, according to an embodiment, when a user watches a predetermined RF broadcast channel and selects a channel up key button or a channel down key button provided in the remote control device, the video display device displays the corresponding input And may switch up or down to the corresponding IP stream channel according to the input.

Accordingly, the user can move to the subchannels in the same manner as the conventional RF broadcast channel switching method, so that no additional operation is required.

The method may further include displaying an RF channel broadcast image corresponding to the RF signal on a display, receiving an input for selecting a channel up key button or a channel down key button included in the remote controller, And switching to a corresponding IP stream channel according to the input.
