Hereinafter, an image display apparatus and method for broadcasting program information using EPG data according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram showing a configuration of an image display device of broadcast program information using EPG data of the present invention. As shown, an image display apparatus of broadcast program information using EPG data includes a communication unit 300, a decoder unit 310, a database 320, a representative image acquisition unit 330, and a network connection unit 340. And a channel manager 350, an image processor 360, and an image display 390.

The communication unit 300 receives a video stream and EPG data of a digital multimedia broadcasting. The communication unit 300 receives a carrier of digital multimedia broadcasting transmitted from the outside through an antenna. The carrier of the digital multimedia broadcasting includes a video stream and EPG data. It is a matter of course that the carrier of the digital multimedia broadcasting includes an audio stream.

The decoder 310 decodes the video stream and EPG data of the digital multimedia broadcasting received by the communication unit 300. The decoder 310 demodulates the digital multimedia carrier received by the communication unit 300 in an orthogonal frequency division multiplex (OFDM) and outputs deinterleaved OFDM symbols. The frequency deinterleaved OFDM symbols are classified into a fast information channel (FIC) and a main service channel (MSC) according to their characteristics.

The decoder 310 decodes the OFDM demodulated data. That is, the FIC symbol and the MSC symbol output from the OFDM demodulator are input and decoded to derive a video stream and an EPG-related multimedia object transform (MOT) object.

In digital multimedia broadcasting, EPG documents are expressed in XML (Extensible Markup Language) format, and are encoded into binary EPG data for transmission. The MOT object is constructed by reading predetermined information from EPG data encoded in binary, and the MOT object is OFDM demodulated and transmitted to the MOT carousel. Therefore, the EPG-related MOT object can be derived by decoding the OFDM demodulated data in the decoder 310.

After deriving the MOT object, the decoder 310 receives and decodes the MOT object. When the decoder 310 decodes the MOT object, the binary EPG data is derived, and the derived binary EPG data is parsed using an XML parser.

In the decoder 310, the video stream and the EPG data are decoded due to the series of operations.

The database 320 stores channel information included in the EPG data decoded by the decoder 310 and representative image information of a broadcast program. The channel information includes information related to all channels on which a plurality of broadcast programs are currently running. That is, the channel information includes a channel identifier for distinguishing a specific channel from other channels, a program identifier for distinguishing a specific program from other programs, and information about a time at which a specific program is started.

The representative image information of the broadcast program is information about an image that can represent one specific program. Representative image information of the broadcast program is included in EPG data and transmitted from a broadcast station. The representative image information of the broadcast program stored in the database 320 includes information on the location where the representative image of the broadcast program exists.

4 is a diagram illustrating a document in an XML format including representative image information of a broadcast program. The XML format document is encoded into binary EPG data, and a broadcasting station composes a MOT object from binary encoded EPG data and transmits it. As shown, the XML document includes information on the description type of the media, information on the elements of the multimedia, information on the mimeValue, and information on the attributes of the URL.

In the complex type field ("complexType name"), "mediaDescriptionType" is input, and the type of the media description is defined. "Multimedia" is input to an element field to connect resources of multimedia. "MimeValue" is input to the first attribute field to indicate the mime type of the resource. In the second attribute field, "url" is input to indicate a multimedia resource. That is, "url" is input to the second attribute field to define a location where the representative image of the broadcast program exists.

As a URL input to the second attribute, a parameter value of a World Wide Web (WWW), a Wireless Application Protocol (WAP), or a ContentName of a MOT is input. The representative image of the specific broadcast program is included in the location of the URL input in the second attribute field.

As such, the representative image information of the broadcast program stored in the database 320 may be said to store information about a location where the representative image exists, rather than an image representing the specific broadcast program itself.

The representative image obtaining unit 330 obtains the representative image of the broadcast program using the representative image information of the broadcast program stored in the database 320.

5 is a block diagram showing in detail the configuration of the representative image acquisition means 330 of FIG. As shown, the representative image acquisition means 330 is composed of a representative image information reader 500 and a representative image extractor 510.

The representative image information reading unit 500 reads representative image information of the broadcast program stored in the database. As described above, the representative image information of the broadcast program stored in the database may be referred to as information on a location where the representative image of the broadcast program exists in the form of a URL. Therefore, the representative image information reading unit 500 reads information on the position where the representative image of the broadcast program exists.

The representative image extracting unit 510 extracts the representative image of the broadcast program using the representative image information of the broadcast program read by the representative image information reader 500. When the representative image information of the broadcast program is in the form of the value of the MOT content parameter, the representative image extractor 510 extracts the representative image of the broadcast program from the MOT object decoded by the decoder. The MOT object includes a file related to a representative image of a broadcast program. The included file has a content parameter value that can be distinguished from other files. That is, the representative image extractor 510 extracts an image corresponding to the value of the MOT content parameter from the MOT object.

When the representative image information of the broadcast program is in the form of WWW or WAP, the representative image extractor 510 extracts the representative image of the broadcast program through a network connection unit described later.

The network access unit 340 connects to the network using the representative image information of the broadcast program input by the representative image extractor 510. When the representative image information of the broadcast program is in the form of WWW or WAP, the network connection unit 340 receives the representative image of the broadcast program by accessing a location where the representative image of the broadcast program exists using the representative image information. . The representative image of the broadcast program received by the network connection unit 340 is input to the representative image extracting unit.

The channel manager 350 processes an operation related to the channel. The channel manager 350 receives the channel information stored in the database 320 and the representative image of the broadcast program acquired by the representative image obtaining unit 330. The channel manager 350 matches the channel information with the representative image of the broadcast program. In matching the channel information with the representative image of the broadcast program, the channel information on which a specific broadcast program is run and the representative image of the broadcast program corresponding thereto are matched.

The image processor 360 processes the representative image of a specific broadcast program among the representative images of the broadcast program matched with the channel information in the channel manager 350 so that the representative image of the broadcast program is displayed on the screen while overlapping with the currently running broadcast program image.

6 is a block diagram illustrating in detail the configuration of the image processor 360 of FIG. 3. As illustrated, the image processor includes a storage unit 600, a representative image selector 610, a graphic user interface 620 (GUI: Graphic User Interface), and a post processor 630.

The storage unit 600 stores the channel information matched by the channel manager and a representative image of the broadcast program. The storage unit 600 receives channel information and a representative image of a broadcast program from the channel manager. The channel information and the representative image of the broadcast program are matched with each other. For example, channel information including a channel number of '9', a title of a broadcasting program 'I know what you did last summer', and a start time of a broadcasting program of '9:00 AM to 11:00 AM' Images that can represent broadcast programs are matched. The storage unit 600 stores matched channel information and a representative image of a broadcast program as described above, for example.

The representative image selector 610 selects a representative image of a broadcast program corresponding to a condition of a broadcast program information display command input through a user interface means from among the representative images of the broadcast program stored in the storage unit 600. When a broadcast program information display command for a specific broadcast program running on a specific channel is input through the user interface means, the representative image selector 610 selects a representative image corresponding to a condition of the broadcast program information display command. The condition of the broadcast program information display command is a specific channel and a specific broadcast program. That is, when the display command is input through the user interface means, the representative image selection unit 610 retrieves the channel information corresponding to the condition of the broadcast program information display command from the storage unit 600. When there is channel information that meets the search result condition, the representative image selecting unit 610 selects a representative image of a broadcast program matching the found channel information.

The graphic user interface 620 converts the representative image of the broadcast program selected by the representative image selector 610 into a specific format and size. The graphic user interface 620 receives a representative image of a broadcast program selected by the representative image selector 610. The format and size of the representative image of the broadcast program input by the graphic user interface 620 may not correspond to the format and size of the digital multimedia broadcasting receiver in displaying the image of the broadcast program information on the screen. Therefore, the graphic user interface 620 converts the representative image of the broadcast program selected by the representative image selector 610 into a specific format and size. The graphic user interface 620 may include a JPEG (Joint Photographic Coding Experts Group) or GIF (GIF) provided by a representative image of an input broadcast program in a specific format, that is, when a digital multimedia broadcasting receiver displays an image of broadcast program information on a screen. Process to convert to Graphics Interchange Format) or PNG (Portable Network Graphics). In addition, the graphic user interface 620 processes the input representative image of the broadcast program to be converted into a specific size, that is, the size provided by the digital multimedia broadcasting receiver in displaying the representative image of the broadcast program on the screen.

The post processor 630 receives the representative image of the broadcast program converted by the graphic user interface 620 and the video stream decoded by the decoder to process the superimposed image on the screen. The post processor 630 receives a representative image of a broadcast program converted into a specific size and format by the graphic user interface 620. The post processor 630 receives a video stream decoded by the decoder.

The decoder unit receives a channel number under the control of the system manager unit by a command input through a user interface means, and outputs a video stream corresponding to the input channel number. The post processor 630 receives a video stream output from the decoder.

The image displayed on the screen is an image of a broadcast program corresponding to the channel number input through the user interface means. That is, the video stream output by the decoder unit is an image processed and output by the post processor 630.

In principle, images of broadcast programs are displayed on the entire screen. Therefore, in order for the image of the broadcast program and the representative image of the broadcast program to be superimposed on the screen, the signal inputted to the allocated area by allocating a predetermined area on the screen is not the video stream data of the broadcast program, It should be data. Therefore, the post processor 630 processes the data of the video stream of the broadcast program and the representative image of the broadcast program so that the representative image of the broadcast program can be allocated and displayed in a specific area of the screen. The area in which the representative image of the broadcast program is displayed on the screen may be changed by the control of the system manager according to a command input through the user interface means.

The image display unit 390 displays a representative image of the specific broadcast program processed by the image processor 360 and an image of the broadcast program on the screen.

The display command of the broadcast program input through the user interface means may be a channel up / down of the representative image or a representative image up / down on the same channel. That is, a key for inputting the plurality of commands may be set in a remote controller or provided in a television receiver so that a display command of a broadcast program can be implemented. That is, when the representative image channel up display command is input through the user interface means, the representative image of the broadcast program one channel higher than the channel corresponding to the representative image of the broadcast program displayed on the current screen is displayed. This may allow the system manager to control the representative image of the broadcast program displayed on the screen according to the channel up / down display command of the representative image by storing the condition of the display command previously input through the user interface means.

In addition, when a representative image down display command is input in the same channel through the user interface means, the representative of the next higher priority broadcast program in the same channel than the broadcast program corresponding to the representative image of the broadcast program displayed on the current screen in time. Allow the image to be displayed. This allows the system manager to control the representative image of the broadcast program displayed on the screen according to the representative image up / down display command on the same channel by storing the condition of the display command previously input through the user interface means.

7 is a diagram illustrating an embodiment in which an image of broadcast program information is displayed on a screen. As shown, the image of the broadcast program currently running and the representative image of the broadcast program corresponding to the condition of the broadcast program information display command input through the user interface means are superimposed and displayed on the screen. Of course, in the lower area of the screen, detailed information corresponding to the representative image of the broadcast program is displayed.

8 is a flowchart illustrating an image display method of broadcast program information using EPG data according to the present invention. As shown, in step S800, the video stream and the EPG data included in the carrier of the digital multimedia broadcasting received from the outside are decoded. The communication unit 300 receives the carrier of the digital multimedia broadcasting transmitted by the broadcasting station. The carrier of the digital multimedia broadcasting received by the communication unit 300 includes a video stream and EPG data. The decoder 310 decodes a carrier of the digital multimedia broadcasting received by the communication unit 300.

Channel information and representative image information of the broadcast program included in the EPG data decoded in step S802 are stored. The database 320 stores channel information included in the EPG data decoded by the decoder 310 and representative image information of the broadcast program. The channel information includes an identifier for identifying a channel with another channel. The representative image information of the broadcast program includes information on a location where the representative image of the broadcast program exists. This is because the EPG data transmitted by the broadcasting station includes information on the location of the representative image of the broadcast program in the form of a URL.

In step S804, representative image information of the stored broadcast program is read. The representative image information reading unit 500 reads out representative image information of the broadcast program stored in the database 320. The representative image information of the broadcast program read by the representative image information reading unit 500 is not information of the image itself, but information about a location where the representative image of the broadcast program exists.

The representative image of the broadcast program is extracted using the representative image information of the broadcast program read in step S806. The representative image extractor 510 extracts the representative image of the broadcast program from the decoder 310 or the network connection unit 340 using the representative image information of the broadcast program read by the representative image information reader 500.

When the representative image information of the broadcast program read out by the representative image information reading unit 500 is in the form of a value of the MOT content parameter, the representative image extracting unit 510 is configured in the MOT object decoded by the decoder 310. Extract the image corresponding to the value of the MOT content parameter.

When the representative image information of the broadcast program read by the representative image information reading unit 500 is in the form of WWW or WAP, the representative image extracting unit 510 connects to the network through the network connection unit 340 to display the broadcast program. Extract representative image information.

In step S808, the channel information and the representative image of the extracted broadcast program are matched and stored. The channel manager 350 receives the channel information stored in the database 320 and the representative image of the broadcast program extracted by the representative image extractor 510. The channel manager 350 matches the input channel information with the representative image of the broadcast program. In the matching, the channel information on which a specific broadcast program is run and the representative image of the broadcast program corresponding thereto are matched. In the matching, matching channel information of a specific broadcast program and a representative image of a broadcast program corresponding thereto are matched. The channel information matched by the channel manager 350 and the representative image of the broadcast program are input to the storage 600 and stored.

In step S810, it is determined whether a broadcast program information display command is input. It is determined whether a broadcast program information display command has been input through the user interface means 380. The display command of the broadcast program information input through the user interface means 380 is input including the condition of the broadcast program information display command for a specific channel and program.

When the broadcast program information display command is inputted as a result of the determination in step S810, the representative image of the broadcast program corresponding to the condition of the display command is selected in step S812. When a broadcast program information display command is input through the user interface means 380, the representative image selector 610 searches the storage 600 for a representative image of a broadcast program corresponding to a condition of the display command. The representative image selector 610 selects a representative image of a broadcast program matching the channel information corresponding to the condition of the display command.

In step S814, the representative image of the broadcast program selected is converted into a specific size and format. The graphic user interface 620 converts the representative image of the broadcast program selected by the representative image selector 610 into a specific format and size in which the digital multimedia broadcasting receiver provides an image of broadcast program information.

In operation S816, the image of the broadcast program and the representative image of the broadcast program are superimposed and displayed on the screen. The post processor 630 receives a representative image of a broadcast program from the graphic user interface 620, and receives a video stream from the decoder 310. The video stream received by the post processor 630 from the decoder 310 becomes a video stream for the broadcast program currently displayed on the screen. The post processor 630 processes the representative image and the video stream of the received broadcast program to be displayed on the screen.

The representative image and the video stream of the broadcast program processed by the post processor 630 are displayed overlapping the screen on the image display unit 390.
