(Step S24).
- the comparison analysis unit 32 determines whether or not the structure of the Web page has changed (step S25).
- Web page The structure of the two is compared with the type, number, and order of both tags, and when any of these changes, it is determined that the structure has changed, and both of these change. V, N, and sometimes the structure changes and it is judged that N.
- the comparison analysis unit 32 determines that the structure of the Web page has changed due to the update (step S25 Yes)
- the comparison analysis unit 32 transmits an activation signal to the message transmission unit 35.
- the message sending unit 35 sends message data that should reset the image extraction range of the Web page to the monitor 26, and the message “Reset Web image display range” appears on the monitor 26 screen. Message is displayed (step S26).
- the comparison analysis unit 32 determines that the structure of the web page has changed due to the update (No in step S25)
- the comparison result is displayed on the screen of the monitor 26 from the memory 31.
- step S27 The processing content of step S27 described above will be specifically described. It is assumed that a specific image from which the Web page force is extracted is displayed on the screen of the monitor 26.
- the comparison analysis unit 32 determines that the content of the tag has changed due to the processing in step S27 (step S27 Yes)
- the comparison analysis unit 32 transmits an activation signal to the updated image generation unit 34.
- the update image generation unit 34 converts the web page newly downloaded in step S21 into image data, sets the extraction area, display size, display position, and display form, and updates the video signal and display settings. Data is generated and transmitted to the video composition unit 25.
- the display size, display position, and display form are currently displayed on the monitor 26 screen. Is set to the same state as The video composition unit 25 synthesizes this updated video signal and the television broadcast video signal instead of the Web page image that has been displayed so far.
- a new composite video signal is generated and transmitted to the monitor 26.
- the monitor 26 plays the composite video signal, and the updated Web image and television broadcast video are simultaneously displayed on the screen (step S28).
- step S27 No when the comparison analysis unit 32 determines that the tag content has not changed by the process of step S27 (step S27 No), it is currently displayed on the screen of the monitor 26.
- the web page image is displayed as it is (step S29).
- the updated image generation unit 34 acquires a new Web page updated from the Web browser 22 in response to the activation signal transmitted from the comparison analysis unit 32 (step S31).
- the updated image generation unit 34 displays the new Web page acquired in step S31 as an HTM.
- the updated image generation unit 34 reads the extracted position data from the memory 31, specifies the extraction area for the updated new Web page based on the extracted position data, and updates the updated video signal. Is generated (step S33). That is, the position and range of the extracted part of the Web page force after the update by this process are the same as the position and range of the extracted part of the Web page image before the update at the coordinate level.
- the extracted position data is obtained when the image extraction unit 23 extracts the display area in the process of processing the image currently displayed on the screen of the monitor 26, that is, after step S03 in the flowchart of FIG. Stored in memory 31.
- the update image generation unit 34 reads the display setting data including the display size setting data, display position setting data, and display form setting data of the image currently displayed on the screen of the monitor 26 from the memory 31.
- the display size, the display position, and the display form are set based on the display setting data to generate display setting data (step S34).
- this process The display size, display position, and display form of the image currently displayed on the screen 26 will remain unchanged.
- the display setting data is currently displayed on the monitor 26 screen!
