[Operation of display device]
Next, main operation contents of the television receiver 1 as a display device will be described. As a basic operation (operation in the normal mode), the television receiver 1 continuously receives a content signal corresponding to the current input target and reception channel, and displays a real-time video display of the received content signal (content Display) and audio output.

When the “input switching” key is operated, the system controller 26 receives this and switches the input target. When the “channel +” key or the “channel−” key is operated, the system controller 26 receives this and switches the reception channel. It is also possible to directly switch the receiving channel to the channel of that number by inputting the channel number of 1 digit to 4 digits using each numeric key ("0" to "9").

When the input target or the reception channel is switched in this way, the received content signal is switched, and thereafter, the video and audio of the new content signal after switching are output. That is, the display content displayed on the display 20 is switched.

Note that the video display on the display 20 in the normal mode is a full-screen display form as shown in FIG. 3 (the outer edge of the drawing represents the outer edge of the display area of the display 20. The same applies to the drawings described later). (A display form in which the frame of the video and the outer edge of the display area of the display 20 substantially coincide). In this way, the video is displayed as large as possible in view of ease of viewing for the user.

Further, the system controller 26 can generate OSD control signals representing OSD display screens such as TV program titles and guides based on the attached information obtained by reception, and display these on the display 20. It has become.

On the other hand, when the “menu” key is operated in the menu mode, the operation mode of the television receiver 1 shifts to the normal mode.

Next, the net mode will be described. There are two forms of the net mode of this embodiment, one is a net application mode that allows individual net contents to be accessed from a net portal screen that displays a list of net applications, and the other is a display 20. This is a ticker mode in which a character string of a predetermined net content is displayed by flowing from the bottom to the top in a band shape at the bottom of the screen.

FIG. 4 is a diagram for explaining the switching operation of each screen, FIG. 5 is an example of a screen in which the mini menu screen is displayed in an overlapping manner on the net portal screen, and FIG. 6 is a screen in which the mini menu screen is displayed in an overlapping manner on the ticker mode screen. For example, FIG. 7 is an enlarged view of a mini menu screen. 4 to 6, “AAA” provides the name of the company or service that provides the net portal screen, “BBB” and “CCC” provide advertising characters, and “DDD” to “SSS” provide net content. Represents the company name or service name.

When the “Internet” key (indicated by “N” in FIG. 4) is pressed in the normal mode (for example, the state of the screen 40), or when the “menu” key is pressed in the normal mode (for example, the screen 40), the menu mode ( For example, when the “Enter” key or the “Internet” key is pressed after shifting to the screen 41), the mode shifts to the net application mode (for example, the screen 42). At this time, the system controller 26 controls the scaler 17 so as to perform a sub-screening process for the video being received. As a result, a display signal having a content that is a composite of the list of network applications and the video content displayed as a sub-screen is sent to the display 20.

As a result, as shown in the screen 42 in FIG. 4, the display form of the display 20 is a form in which a net portal screen and a video (display content) converted into a sub-screen are displayed in parallel. The subscreen image is displayed at a position that does not interfere with (does not overlap) the net portal screen (for example, at the upper right of the display 20). Note that the audio corresponding to the video with a small screen is output.

Note that when an operation for switching the input target or the reception channel is performed in a state in which the sub-screen image is displayed, the system controller 26 switches the input target or the reception channel while maintaining the display form. .

Therefore, the user operates the “input switching” key, the “channel +” key, the “channel−” key, or the like while the net portal screen is displayed on the display 20 to switch the subscreen image. The video of the desired content signal can be viewed.

Next, when “show Ticker” is selected and operated from the list of items on the left end of the screen in the net application mode (for example, the screen 42), the mode shifts to the ticker mode (for example, the screen 43). At this time, the system controller 26 controls the Internet processing circuit 29 so as to perform a sub-screening process of predetermined net contents. As a result, a display signal of the content that is a composite of the video of the content being received and the net content that has been converted into a sub-screen is sent to the display 20.

As a result, as shown in the screen 43 of FIG. 4, the display form of the display 20 is a form in which the video (display content) being received and the net content converted into a sub-screen are displayed in parallel. The sub-screened net content is displayed in a ticker manner in a band shape at a position (for example, the lower part of the display 20) that does not interfere with (overlap) the video. Audio corresponding to the image being received is output.

In addition, when a desired application is selected and operated from the list of net applications in the net application mode (for example, the screen 42), a connection is made to the site of the application and a screen for displaying the contents of the site (for example, the screen 44) is displayed. .

Further, when a green color key “G” is pressed on a screen displaying the contents of the site (for example, the screen 44), the screen (for example, the screen) that allows the site to be evaluated or added to favorites. 45). In the net application mode (for example, the screen 42), even when the green color key “G” is pressed while the cursor is positioned on a desired application, the site on the cursor is evaluated or added to the favorites. The screen shifts to a screen that can be used (for example, screen 45).

Next, a net application mode (for example, the screen 42), a ticker mode (for example, the screen 43), a screen for displaying the contents of the site (for example, the screen 44), a screen for evaluating the site and adding it to favorites (for example, When the “menu” key is pressed on any of the screens 45), the mode shifts to the mini menu mode. At this time, the system controller 26 generates an OSD control signal representing the mini menu screen and sends it to the OSD display circuit 28. As a result, a display signal of the content in which the mini menu screen and the video of the content being received (including the net content) are combined is sent to the display 20.

As a result, the display form of the display 20 is a form in which the mini menu screen is displayed in parallel with the video of the content being received (including the net content) as shown in the screen 46 of FIG. For example, when the network application mode (for example, the screen 42) is shifted to the mini menu mode, the mini menu screen 51 is displayed in the upper left of the screen 42 as shown in the screen 50 of FIG. Further, for example, when the mode is changed from the ticker mode (for example, the screen 43) to the mini menu mode, the mini menu screen 51 is displayed in the upper left of the screen 43 as shown in the screen 60 of FIG.

On the other hand, when the “Cancel” key or “Exit” key is operated in the mini menu mode, the mini menu screen displayed in an overlapping manner is deleted and the mini menu mode is terminated.
