In addition, the functions performed in each block are intended to illustrate the embodiments of the present invention, and the specific operations and apparatuses do not limit the scope of the present invention.

A method of processing item information data of the image display apparatus 100 having the above-described structure will be described with reference to FIGS. 3 to 6 with reference to the operation of the controller 170.

3 to 6 are flowcharts illustrating a method of processing item information data together with image data according to the present invention.

The function of the control unit 170 for processing the item information data is stored in the routine (S100) and the existing storage unit 140 for displaying the item information data on the display unit 180 and stores it in the storage unit 140. A routine S200 for calling item information data is included. 3 shows two routines of such a control unit 170.

4 is a flowchart illustrating a western routine of the routine S100 for displaying the item information data on the display unit 180 and storing the item information data in the storage unit 140.

Referring to FIG. 4, in order to display the received item information data on the display unit 180 and store it in the storage unit 140, the controller 170 first receives a data signal input from the aforementioned data receiver 105. The process goes to step S110 of reading.

Next, the controller 170 determines whether the received data signal includes not only an image content signal but also an associated item information data signal (S120).

 In this case, if the item information data signal is not included in the received data signal, the process returns to the standby state before the step S110 of reading the data signal input from the data receiving unit 105. If the received data signal includes the item information data signal, the controller 170 temporarily stores the received item information data in the storage 140 or the internal memory 171 (S130).

Thereafter, the specific item related to the received item information data is synchronized with the time when the first item is displayed on the screen of the display unit 180, and the controller 170 generates an alarm message informing the user that the specific item information data has been received. The control signal is output to the OSD controller 160 to be displayed on the screen of the display unit 180 (S140).

As will be described later, the alarm message may take the form of a specific icon or may be a text form and an image containing a specific content. For example, it may be text and an image "Information about item XXX has been received."

After the alarm message is output to the display unit 180, the controller 170 reads from the user input interface unit 150 whether an input signal for which the user wants to check the details of the alarm message has been received (S150).

When it is determined that the user inputs a signal for confirming detailed item information (S160), the controller 170 reads detailed item information data temporarily stored in the storage 140 or the internal memory 171, and the information is read. An information display window displaying detailed item information by outputting a control signal for outputting the display unit 180 to the display unit 180 in the form of a display window is displayed on the display unit 180 (S170).

The displayed detailed item information and the image in which the corresponding item appeared may be stored together with the storage 140. Preferably, the video image and the item information data may be stored in the form of a thumbnail image included together.

On the other hand, if the user does not input a signal for checking the detailed item information (S160), it is determined whether the time that the alarm message is displayed on the display unit 180 exceeds the time set in advance (S191), If it is determined that the set time has not been exceeded, the process returns to step S140 of outputting the alarm message to the display unit 180 to continue displaying the alarm message. Preferably, the set time may be from a time point at which the corresponding item is first displayed to a time point at which the image is switched and the item is excluded from the image. If it is determined that the preset time is exceeded, the controller 170 outputs a signal for stopping displaying the alarm message to the display unit 180 (S192). In this case, the control unit 170 returns to the previous step S110.

5 is a step that can be added between the step S130 and the step S140, it is determined that the relationship between the user's interest keyword stored in the storage 140 and the received item information data, it is determined that the relationship Is a diagram for explaining a step of setting to output an alarm message only when a message is generated.

Referring to FIG. 5, it may be included in a step S131 of calling a user's interest keyword stored between the step S130 and the step S140. In addition, the controller 170 may generate a control signal for outputting an alarm message in step S140 only when it is determined that there is a correlation between the called interest keyword and the received item information data. . On the other hand, if it is determined that there is no relevance, the process may return to step S131 or set not to display an alarm message. In this way, the user can be configured to only output alarm messages for items of the field of interest.

6 is a flowchart for explaining a subroutine of the routine S200 for calling item information data stored in the existing storage unit 140.

Referring to FIG. 6, first, the controller 170 reads a command signal of a user input through the user input interface unit 150 (S210), and as a result, determines whether the command signal is a data call signal (S220). That is, it is determined whether the user's command signal is a signal for calling the item information data stored in the storage 140 or if the call signal is correct, the signal for calling the specific item information data.

If it is not the data call signal, the standby state before the step S210 is maintained. If it is determined that the data call signal corresponds, the corresponding item information data stored in the storage unit 140 is read (S230).

Next, the controller 170 calls the corresponding item information data that the user wants to check, and outputs a control signal for displaying the corresponding item information list to the display unit 180 (S240). On the other hand, the OSD controller 160 ) Is provided separately from the control unit 170 to output the control signal as described above to the OSD control unit 160, the OSD control unit 160 to generate a selected item information data list according to the received control signal The signal is transmitted to the display unit 180.

Next, after displaying the corresponding item information data list on the display unit 180, the controller 170 reads the user's input signal input from the user input interface unit 150 (S250).

The control unit 170 reads whether or not the input signal is a signal desired to confirm specific item information data in the corresponding item information data list (S260).

As a result of the reading, if the item information data list does not include the specific item information data desired by the user and the item information data is read out as missing from the list, the process returns to the previous step S210.

On the other hand, if it is determined that the user wants to select specific item information as the result of reading the specific item information data desired by the user, the controller 170 controls to call the storage unit 140 with detailed information about the selected item. Outputs a signal, and outputs a control signal for outputting detailed item information to the display unit 180 (S280). In this case, as in step S240, the OSD controller 160 is provided separately from the controller 170. In the case of the configuration, the control signal as described above is output to the OSD control unit 160, and the OSD control unit 160 generates a signal for generating an information display window for displaying detailed item information data according to the received control signal ( 180).

FIG. 7 illustrates a method for displaying that item information data is included in specific image content in an electronic program guide (hereinafter referred to as EPG) according to an embodiment of the present invention.

While the image content is displayed on the screen of the display unit and the received item information data can be displayed on the screen according to the steps of FIGS. 3 to 6, the item information data is included in the specific image content before the image content is provided to the user.
