The number key group 350 includes a plurality of number keys respectively corresponding to the numbers 1 to 12.
Each numeric key of the numeric key group 350 is a key for causing the remote control signal output unit 305 to output a remote control signal of a corresponding numeric channel number when the remote control 300 is in the TV mode and the user performs a pressing operation. It is.

  Each numeric key of the numeric key group 350 is a key for outputting a remote control signal having a corresponding numerical value from the remote control signal output unit 305 when the remote control 300 is in the IT mode and the user performs a pressing operation.

  Next, image generation processing performed by the video signal generation device 100 will be described. The image generation process is a process performed by the control unit 120 according to an image generation program stored in the nonvolatile memory 142.

  FIG. 6 is a flowchart of the image generation process. Referring to FIG. 6, in step S110, control unit 120 executes a key reception process to be described later. The key reception process is executed in parallel independently of the image generation process. Thereafter, the process proceeds to step S120.

  In step S120, the control unit 120 sequentially executes the above-described four new arrival information acquisition programs one by one, and performs processing based on each new arrival information acquisition program (hereinafter also referred to as new arrival information acquisition processing). The four new arrival information acquisition programs may be executed simultaneously in parallel. The new arrival information acquisition process is executed in parallel with the image generation process separately from the image generation process.

  Here, each of four new arrival information acquisition programs, that is, a weather forecast acquisition program, an EPG information acquisition program, a news acquisition program, and a mail acquisition program will be described.

  The weather forecast acquisition program is a program in which the control unit 120 is connected to the network 50 and acquires weather forecast information corresponding to preset area information from a predetermined Internet address (URL). Here, the area information is information input by the user using the keyboard 172 or the mouse 174, and is stored in the nonvolatile memory 142. An example of regional information is a prefecture. Another example of regional information is 7-digit postal code information.

  The EPG information acquisition program is a program in which the control unit 120 is connected to the network 50 and acquires EPG information corresponding to preset area information from a predetermined Internet address (URL). The frequency with which the control unit 120 acquires EPG information is, for example, twice a day. Further, the control unit 120 may perform the process of acquiring EPG information when receiving an instruction from the user via the remote controller 300.

  The control unit 120 stores the acquired EPG information in the nonvolatile memory 142. If the EPG information is already stored in the nonvolatile memory 142, the control unit 120 causes the nonvolatile memory 142 to overwrite and store the acquired EPG information. Therefore, the nonvolatile memory 142 always stores the latest EPG information.

  The news acquisition program is a program in which the control unit 120 is connected to the network 50 and acquires news from a predetermined Internet address (URL).

  In the mail acquisition program, the control unit 120 connects to the network 50, logs in to a mail server having a domain name or IP address designated in advance using preset user information, This is a program for acquiring a title corresponding to the new mail.

  Here, the user information is information input by the user using the keyboard 172 or the mouse 174, and is information such as an ID and a password. The user information is stored in the nonvolatile memory 142. The control unit 120 causes the non-volatile memory 142 to store the acquired new mail sender and the title information corresponding to the new mail. When an image based on the mail acquisition program is displayed on the display unit 280, the transmission source of the new mail and the title corresponding to the new mail are displayed.

  Note that initial values (hereinafter also referred to as initial setting values) of setting values used in each of the weather forecast acquisition program, EPG information acquisition program, news acquisition program, and mail acquisition program are stored in advance in the nonvolatile memory 142 (or recording). Medium 70). Hereinafter, a data table including a plurality of initial setting values is also referred to as an initial setting value table. Therefore, the initial setting value table is stored in advance in the nonvolatile memory 142 (or the recording medium 70). In the present embodiment, an initial setting value table T100 described below is stored in advance in the nonvolatile memory 142 (or the recording medium 70).

  FIG. 7 is a diagram illustrating an initial setting value table T100 as an example. Referring to FIG. 7, initial setting value table T100 corresponds to a program number, an execution program, a signal mode, a screen mode, permission or disapproval of immediate display, coordinates of the upper left corner of the rectangle, height, width, and the like. Is a table set as an initial setting value.

  Each initial setting value in the initial setting value table T100 can be changed in a setting image described below. The setting image includes a PC setting image for setting (changing) a setting value used in a program executed by the video signal generation device 100 and a setting value used by a program executed by the video output device 200. There are TV setting images for setting (changing).

  The PC setting image 700 described below is an image displayed on the display unit 280 when the user presses the setting key 346 when the remote controller 300 is in the IT mode.

  FIG. 8 shows a PC setting image 700. Referring to FIG. 8, setting content display areas 710, 720, 730, 740, 750, 762, 764, 772, 774 are arranged in PC setting image 700. In the following, the state in which the contents displayed in each of the setting content display areas 710, 720, 730, 740, 750, 762, 764, 772, and 774 can be edited is also referred to as an edit mode. In the setting content display areas 710, 720, 730, 740, 750, 762, 764, 772, and 774, initial setting values based on the initial setting value table T100 are displayed.

  The setting content display areas 710, 720, 730, 740, 750, 762, 764, 772, and 774 are sequentially selected by the user pressing the cursor key 342A or the cursor key 342B of the remote controller 300 in the IT mode. If the user presses the enter key 344 of the remote controller 300 in the IT mode while the setting content display area is in the selected state, the setting content display area in the selected state enters the edit mode.

  When each of the setting content display areas 710, 720, 730, 740, and 750 is in the edit mode, if the user presses the cursor key 342A or the cursor key 342B of the remote controller 300 in the IT mode, the edit mode is set. The display contents in the content display area are sequentially changed.

A numerical value corresponding to the numeric key is displayed in the setting content display area of the edit mode. If the user presses the enter key 344 of the remote controller 300 in the IT mode while the setting content display area is in the editing mode, the editing mode of the setting content display area is canceled.

  The setting content display area 710 is an area for setting a program number. The program number can be set in the range of “1” to “4”. Each time the program number displayed in the setting content display area 710 is changed, each of the setting content display areas 720, 730, 740, 750, 762, 764, 772, 774 is stored in the initial setting value table T100. The initial setting value corresponding to the program number is displayed.

  The setting content display area 720 is an area for setting a new arrival information acquisition program to be assigned to the program number displayed in the setting content display area 710. As described above, the new arrival information acquisition program is the four programs of the weather forecast acquisition program, the EPG information acquisition program, the news acquisition program, and the mail acquisition program.

  The setting content display area 730 is an area for setting a signal mode. There are four types of signal modes depending on the combination of the image size based on the video signal output from the video signal generation device 100 to the video output device 200 and the frequency of the vertical synchronization signal (hereinafter also referred to as the vertical synchronization frequency). The four signal modes are, for example, “1366 × 768, 60 Hz”, “1366 × 768, 70 Hz”, “683 × 768, 60 Hz”, “683 × 768, 70 Hz”. Note that the signal mode is not limited to four, and may be three or less or five or more.

  The setting content display area 740 is an area for setting a screen mode. As described above, there are three types of screen modes: TV-in-PC mode, PC-in-TV mode, and TV-by-PC mode. Character strings indicating the TV-in-PC mode, the PC-in-TV mode, and the TV-by-PC mode are “TV in PC”, “PC in TV”, and “TV by PC”, respectively.

  In the setting content display area 750, when the new arrival information acquisition program displayed in the setting content display area 720 is executed and there is new arrival information to be described later, the new arrival information is immediately displayed on the display unit 280. This is an area for setting whether to permit or not. Accordingly, the setting content in the setting content display area 750 is either “permitted” or “not permitted”. The news acquisition program and the mail acquisition program are “permitted” as an initial setting. In addition, the weather forecast acquisition program and the EPG information acquisition program are “not permitted” as an initial setting.

  The setting content display areas 762 and 764 are areas in which the upper left x coordinate and y coordinate of the display area of the TV image or PC image are set in the two-screen display state. In the TV-in-PC mode, the setting content display areas 762 and 764 are areas for setting the upper left x coordinate and y coordinate of the TV image display area.

  In the PC-in-TV mode, the setting content display areas 762 and 764 are areas in which the upper left x coordinate and y coordinate of the PC image display area are set. In the TV-by-PC mode, the setting content display areas 762 and 764 are areas in which the upper left x coordinate and y coordinate of the PC image display area are respectively set.

  In the following, an area for displaying a PC image displaying information acquired by executing the new arrival information acquisition program displayed in the setting content display area 720 is also referred to as an information display area. In the following, an area for displaying a TV image is also referred to as a TV image display area.

  The setting content display areas 772 and 774 are areas for setting the height and width of the information display area or the TV image display area, respectively. In the TV-in-PC mode, the setting content display areas 772 and 774 are areas for setting the height and width of the TV image display area, respectively.

  In the PC-in TV mode, the setting content display areas 772 and 774 are areas for setting the height and width of the information display area, respectively. In the TV by PC mode, the height and width of the information display area are areas to be set.

When the PC setting image 700 is displayed on the display unit 280, the user can change the initial setting values respectively corresponding to the program numbers 1 to 4 by pressing the remote control 300 in the IT mode. When the user presses the setting key 346 of the remote controller 300 in the IT mode again and the initial setting value is changed, the control unit 120 changes the corresponding initial setting value in the initial setting value table T100. And stored in the nonvolatile memory 142 (or the recording medium 70). Thereafter, the display unit 280 displays an image before the PC setting image 700 is displayed.

FIG. 9 is a flowchart of the new arrival information acquisition process. As an example, a new arrival information acquisition process performed by the weather forecast acquisition program of program number 1 will be described. Referring to FIG. 9, in step S210, information acquisition processing is performed. In the information acquisition process, a process according to the program to be executed is performed. Here, since the program to be executed is the weather forecast acquisition program, the following information acquisition process K is performed.

  In the information acquisition process K, the control unit 120 connects to the network 50 and acquires weather forecast information corresponding to preset area information from a predetermined Internet address (URL). Thereafter, the process proceeds to step S220.

  In step S220, it is determined whether the information acquired in step S210 is new arrival information. Specifically, the control unit 120 determines whether or not the same information as the information acquired in step S <b> 210 is stored in the nonvolatile memory 142. If YES in step S220, the process proceeds to step S222. On the other hand, if NO at step S220, the new arrival information acquisition process ends.

  In step S222, the control unit 120 stores the information acquired in step S210 in the nonvolatile memory 142 in association with the program number. Thereafter, the process proceeds to step S224.

  In step S224, it is determined whether immediate display is permitted. Specifically, the control unit 120 determines whether or not the setting content of the immediate display of the program corresponding to the new arrival information acquisition process stored in the nonvolatile memory 142 is “permitted”. If YES in step S224, the process proceeds to step S226. On the other hand, if NO at step S224, the new arrival information acquisition process ends.

  In step S226, the control unit 120 generates a PC image based on the information acquired in step S210 and various setting values of the program corresponding to the new arrival information acquisition process.

  FIG. 10 is a diagram illustrating an image generated by the video signal generation device 100. FIG. 10A is a diagram showing a PC image 600 as an example. With reference to FIG. 10A, an area 610R and an area 620R are arranged in the PC image 600. A region 620R of the PC image 600 is an information display region.

  The same color (for example, black) is colored in the region 610R. In the area 620R, information obtained by executing the program corresponding to the new arrival information acquisition process is displayed.

After the process of step S226, the process proceeds to step S228.
In step S228, the control unit 120 transmits the generated PC image signal (hereinafter also referred to as a PC image signal) to the video output apparatus 200 via the video cable 132. The transmitted PC image signal includes a vertical synchronization signal having a vertical synchronization frequency (for example, 60 Hz) set corresponding to the program number. Thereafter, the new arrival information acquisition process ends.

  In addition, although the above-mentioned new arrival information acquisition process demonstrated the process performed by the weather forecast acquisition program corresponding to the program number 1, the process similar to what was mentioned above is performed also about the program numbers 2-4.

  In the video output device 200, image signal reception processing is performed. It is assumed that a TV image 600B shown in FIG. 10B is displayed on the display unit 280 of the video output device 200.

  FIG. 11 is a flowchart of the image signal reception process. Referring to FIG. 11, in step S <b> 510, control unit 220 determines whether a PC image signal has been received from video signal generation device 100. If YES in step S510, the process proceeds to step S520. On the other hand, if NO at step S510, the process at step S510 is performed again.

  In step S520, signal analysis processing is performed. In the signal analysis process, the control unit 220 determines the image size of the image based on the received PC image signal and the vertical synchronization frequency of the vertical synchronization signal included in the received PC image signal. Thereafter, the process proceeds to step S530.

  In step S530, control unit 220 determines whether or not the signal mode based on the combination of the determined image size and the determined vertical synchronization frequency is a registered signal mode. Specifically, the control unit 220 stores a setting value (hereinafter also referred to as a reception signal correspondence setting value) corresponding to a signal mode based on a combination of the determined image size and the determined vertical synchronization frequency in the nonvolatile memory 242. It is determined whether or not it is stored. In the following, a data table composed of a plurality of received signal correspondence setting values is also referred to as a reception signal correspondence setting value table. The received signal correspondence set value table is stored in the nonvolatile memory 242 in advance. In the present embodiment, it is assumed that what is stored in the nonvolatile memory 242 is a reception signal correspondence setting value table T100A described below.

  FIG. 12 is a diagram illustrating a received signal corresponding set value table T100A as an example. Referring to FIG. 12, received signal correspondence setting value table T100A is a table in which signal mode, screen mode, coordinates, height, and width are set as reception signal correspondence setting values in correspondence with signal mode numbers.

  Note that each received signal corresponding setting value in the received signal corresponding setting value table T100A can be changed in a TV setting image described below. As described above, the TV setting image is a setting image for setting (changing) a setting value used in a program executed by the video output device 200.

  The TV setting image is an image displayed on the display unit 280 when the user presses the setting key 346 when the remote controller 300 is in the TV mode.

  FIG. 13 shows a TV setting image 700A. Referring to FIG. 13, setting content display areas 710A, 730A, 740A, 762A, 764A, 772A, and 774A are arranged in TV setting image 700A. Hereinafter, a state in which the contents displayed in each of the setting content display areas 710A, 730A, 740A, 762A, 764A, 772A, and 774A can be edited is also referred to as an edit mode. In each of the setting content display areas 710A, 730A, 740A, 762A, 764A, 772A, and 774A, reception signal corresponding setting values based on the reception signal corresponding setting value table T100A are displayed.

  The setting content display areas 710A, 730A, 740A, 762A, 764A, 772A, and 774A are sequentially selected by the user pressing the cursor key 342A or the cursor key 342B of the TV mode remote control 300. If the user presses the enter key 344 of the remote control 300 in the TV mode while the setting content display area is in the selected state, the setting content display area in the selected state is in the edit mode.

  When each of the setting content display areas 710A, 730A, and 740A is in the edit mode, if the user presses the cursor key 342A or the cursor key 342B of the remote controller 300 in the TV mode, the setting content display area in the edit mode is displayed. Display contents are changed sequentially.

  When each of the setting content display areas 710A, 762A, 764A, 772A, and 774A is in the edit mode, if the user presses the number key of the number key group 350 of the remote control 300 in the TV mode, the pressing operation is not performed. A numerical value corresponding to the numeric key is displayed in the setting content display area of the edit mode. If the user presses the enter key 344 of the remote controller 300 in the TV mode while the setting content display area is in the editing mode, the editing mode of the setting content display area is canceled.

  The setting content display area 710A is an area for setting a signal mode number. The signal mode number can be set in the range of “1” to “4”. Each time the signal mode number displayed in the setting content display area 710A is changed, each of the setting content display areas 730A, 740A, 762A, 764A, 772A, 774A includes a signal in the received signal corresponding setting value table T100A. The received signal correspondence setting value corresponding to the mode number is displayed.

  The setting content display area 730A is an area for setting a signal mode to be assigned to the signal mode number displayed in the setting content display area 710. There are four types of signal modes depending on the combination of the image size of the image based on the PC image signal received from the video signal generation device 100 and the vertical synchronization frequency of the vertical synchronization signal included in the received PC image signal. is there. The four signal modes are “1366 × 768, 60 Hz”, “1366 × 768, 70 Hz”, “683 × 768, 60 Hz”, and “683 × 768, 70 Hz” described above. Note that the signal mode is not limited to four, and may be three or less or five or more.

  Since setting content display area 730A is similar to setting content display area 730 described above, detailed description will not be repeated.

  Since the setting content display areas 762A and 764A are similar to the setting content display areas 762 and 764 described above, detailed description will not be repeated. Since setting content display areas 772A and 774A are similar to setting content display areas 772 and 774 described above, detailed description will not be repeated.

  When the TV setting image 700A is displayed on the display unit 280, the user can change the reception signal corresponding setting values corresponding to the signal mode numbers 1 to 4 by pressing the remote control 300 in the TV mode described above. it can. When the user again presses the setting key 346 of the TV mode remote controller 300, if the received signal corresponding setting value is changed, the control unit 220 receives the corresponding reception in the received signal corresponding setting value table T100A. The signal corresponding setting value is changed and stored in the nonvolatile memory 242. Thereafter, the display unit 280 displays an image before the TV setting image 700A is displayed.

  Note that the received signal correspondence setting value table T100A may not be stored in the nonvolatile memory 242 in advance. In this case, the data of the received signal corresponding setting value table T100A is stored in the nonvolatile memory 242 by the following setting data replication processing.

  FIG. 14 is a flowchart of the setting data replication process. Referring to FIG. 14, in step S610, control unit 220 determines whether or not recording medium 70 is accessible. If YES in step S610, the process proceeds to step S620. On the other hand, if NO at step S610, the process at step S610 is performed again.

  In step S620, the control unit 220 determines whether or not the data of the initial setting value table T100 is recorded on the recording medium 70. If YES in step S620, the process proceeds to step S630. On the other hand, if NO at step S620, the process at step S610 is performed again.

  In step S630, a duplication process is performed. In the duplication processing, the control unit 220 accesses data in the initial setting value table T100 in the recording medium 70. Then, the control unit 220 uses the signal mode, screen mode, coordinates, height, and width data corresponding to each execution program number in the initial setting value table T100 as each signal mode in the received signal corresponding setting value table T100A. The data is stored in the nonvolatile memory 242 as signal mode, screen mode, coordinates, height, and width data corresponding to the number. Thereafter, the setting data replication process ends.

  Through the above processing, the data in the initial setting value table T100 stored in the recording medium 70 can be easily stored in the nonvolatile memory 242 as the reception signal corresponding setting value in the reception signal corresponding setting value table T100A. . Therefore, the TV setting image 700A is displayed on the display unit 280, and there is an effect that it is possible to eliminate the user's trouble of setting each reception signal corresponding setting value of the reception signal corresponding setting value table T100A.

  When the received signal corresponding set value table T100A is stored in advance in the non-volatile memory 242, if the setting data duplication process described above is performed, even if there is a data change in the initial set value table T100, the received data There is an effect that the data change can be easily reflected in the signal correspondence set value table T100A.

  Referring to FIG. 11 again, if YES in step S530, the process proceeds to step S540. On the other hand, if NO at step S530, the process at step S510 is performed again.

  If NO is determined in step S530, that is, if the received PC image signal is not already registered, the control unit 220 displays the PC image based on the received PC image signal in the entire area of the display unit 280. May be displayed.

  In step S540, a composite image generation process is performed. In the composite image generation process, the control unit 220 determines the signal mode of the received PC image signal based on the received signal corresponding setting value table T100A stored in the nonvolatile memory 242. Then, based on the screen mode, coordinates, height, and width data corresponding to the determined signal mode, the control unit 220 generates a composite image that simultaneously displays the TV image and the PC image.

  Referring to FIG. 10 again, FIG. 10C is a diagram showing a composite image 600C1 as an example. Referring to FIG. 10C, composite image 600C1 is a composite image displayed on display unit 280 in the PC-in TV mode. An area 610R in the composite image 600C1 is a TV image display area. An area 620R in the composite image 600C1 is an information display area. In the area 620R, weather information obtained by processing of the weather information acquisition program is displayed.

  FIG. 15B is a diagram showing a composite image 600C2 as an example. The composite image 600C2 is a composite image displayed on the display unit 280 in the TV in PC mode. An area 610RB in the composite image 600C2 is a TV image display area. The size of the area 610RB is 640 dots wide and 480 dots long. The control unit 220 reduces the TV image 600B of FIG. 10B to the size of the area 610RB. Then, the reduced TV image (hereinafter also referred to as a reduced TV image) is displayed in area 610RB.

  An area 620RB in the composite image 600C2 is an information display area. In area 620RB, EPG information obtained by the processing of the EPG information acquisition program is displayed.

  FIG. 15C illustrates a composite image 600C3 as an example. The composite image 600C3 is a composite image displayed on the display unit 280 in the TV by PC mode. An area 610RC in the composite image 600C3 is a TV image display area. The size of the area 610RC is 683 dots wide and 512 dots long. The control unit 220 reduces the TV image 600B of FIG. 10B to the size of the area 610RC. Then, the reduced TV image is displayed in the area 610RC. An area 620RC in the composite image 600C3 is an information display area. In the area 620RC, news information obtained by the processing of the news acquisition program is displayed.

  Referring to FIG. 11 again, when the process of step S540 is completed, the process proceeds to step S550.

  In step S550, control unit 220 displays the generated composite image on display unit 280 in a corresponding screen mode (for example, PC-in-TV mode). Thereafter, the process proceeds to step S560.

  In step S560, control unit 220 performs an audio output switching process in accordance with the screen mode. When the screen mode is, for example, the PC-in TV mode, the control unit 220 causes the left speaker 290A to output a sound obtained by synthesizing the main (left) sound corresponding to the TV image and the sound corresponding to the PC image. . In addition, the control unit 220 causes the right speaker 290B to output sound corresponding to the TV image. That is, as a whole, the audio corresponding to the TV image is mainly output.

  Further, when the screen mode is, for example, the TV-in-PC mode, the control unit 220 generates, from the left speaker 290A, a sound obtained by synthesizing the main (left) sound corresponding to the TV image and the sound corresponding to the PC image.

  Further, when the screen mode is, for example, the TV by PC mode, the control unit 220 outputs a sound obtained by synthesizing the main (left) sound and the sub (right) sound corresponding to the TV image from the left speaker 290A. Let In addition, the control unit 220 causes the right speaker 290B to output sound corresponding to the PC image. That is, as a whole, the sound corresponding to the TV image and the sound corresponding to the PC image are output equally. Thereafter, the process proceeds to step S570.

  In step S570, control unit 220 determines whether a predetermined condition is satisfied. An example of the predetermined condition is, for example, a condition that the video signal generating device 100 is turned off and the PC image signal is no longer transmitted from the video signal generating device 100. An example of the predetermined condition is a condition that the user presses the return key 348 with the remote controller 300 in the TV mode. An example of the predetermined condition is a condition that the same composite image is displayed on the display unit 280 for a predetermined time (for example, 10 minutes) or longer.

  If YES in step S570, the process proceeds to step S572. On the other hand, if NO at step S570, the process at step S510 is performed again.

  In step S572, the display of the composite image is canceled. Specifically, the control unit 220 switches the image displayed on the display unit 280 from the composite image to the TV image. Thereafter, the process proceeds to step S574.

  In step S574, the audio output switching is canceled. Specifically, control unit 220 returns the sound output from left speaker 290A and right speaker 290B to the state before the process of step S560 is performed. Thereafter, the process of step S510 is performed again.

  With the above processing, the video output device 200 has a predetermined condition (for example, when it no longer receives a PC image signal for displaying an image displaying information from the video signal generation device 100). The screen configuration that hinders viewing is canceled, and normal television display can be performed.

Referring to FIG. 6 again, after the process of step S120, the process proceeds to step S122.
In step S122, control unit 120 waits for a predetermined time (for example, 30 minutes). Thereafter, the process of step S120 is performed again.

  Next, the key reception process performed in step S110 of FIG. 6 will be described. As described above, the key reception process is executed in parallel independently of the image generation process.

  FIG. 16 is a flowchart of key reception processing. Referring to FIG. 16, in step S111, control unit 120 determines whether or not a remote control signal has been received. If YES in step S111, the process proceeds to step S112. On the other hand, if NO at step S111, the process at step S111 is performed again.

  In step S112, it is determined whether or not the received remote control signal is valid. Specifically, the remote control signal received by the control unit 120 is a remote control signal generated by the user's pressing operation of any one of the numeric keys “1” to “4” of the numeric key group 350 of the IT mode remote control 300. It is determined whether or not.

  If YES in step S112, the process proceeds to step S113. On the other hand, if NO at step S112, the process at step S111 is performed again.

  In step S113, control unit 120 determines whether or not information is stored in nonvolatile memory 142 by executing a program having a program number corresponding to the number of the numeric key corresponding to the received remote control signal. If YES in step S113, the process proceeds to step S114. On the other hand, if NO at step S113, the process at step S111 is performed again.

  In step S114, the control unit 120 reads information stored in the nonvolatile memory 142 by executing a program having a program number corresponding to the number of the numeric key corresponding to the received remote control signal. For example, if the numeric key is “1”, the control unit 120 reads the weather forecast information stored in the nonvolatile memory 142 by executing the weather forecast acquisition program with the program number 1. Thereafter, the process proceeds to step S116.

  In step S116, the control unit 120 generates a PC image based on the information acquired in step S114 and various setting values of the program corresponding to the new arrival information acquisition process. Since the PC image generation method is the same as that described in step S226 of FIG. 9 described above, detailed description will not be repeated. Thereafter, the process proceeds to step S118.

  In step S118, the same processing as step S228 of FIG. 9 described above is performed, and thus detailed description will not be repeated. Thereafter, the process of step S111 is performed again.

  Then, in the video output device 200, the above-described image signal reception process of FIG. 11 is performed, and a composite image is displayed on the control unit 280.

  With the above processing, there is an effect that the user can know the information he wants to know.

  As described above, in the video system 1000 according to the present embodiment, the video output device 200 uses the PC image and the screen image registered in advance according to the type of the video signal received from the video signal generation device 100. TV images are displayed simultaneously. Therefore, there is no need for a communication path or the like for transmitting position information for displaying a PC image on the display unit 280.

  Therefore, according to the video system 1000 in the present embodiment, it is possible to provide a video output device that can improve the degree of freedom in displaying an image based on each of two or more different video signals at low cost. Play.

  Further, according to the video system 1000 in the present embodiment, the video signal is output to the video output device that improves the degree of freedom of image display based on each of two or more different video signals at low cost. The video signal generating device can be provided.

<Second Embodiment>
In the first embodiment, the PC image enlargement or reduction process is not performed in the two-screen display state. In the present embodiment, processing for enlarging or reducing a PC image will be described.

  Note that the video system in the present embodiment is similar to video system 1000 in the first embodiment, and therefore detailed description will not be repeated. In the present embodiment, video signal generation device 100 performs image generation processing A.

  FIG. 17 is a flowchart of the image generation process A. Referring to FIG. 17, image generation process A differs from image generation process of FIG. 6 in that step S110A is performed instead of step S110 and step S120A is performed instead of step S120. . Other than that, it is the same as the image generation processing, and therefore detailed description will not be repeated.

  In step S110A, key reception processing A is performed. The key reception process A will be described later.

  In step S120A, control unit 120 executes the above-described four new arrival information acquisition programs one by one in order, and performs processing based on each new arrival information acquisition program (hereinafter also referred to as new arrival information acquisition processing A). The four new arrival information acquisition programs may be executed simultaneously in parallel. The four new arrival information acquisition programs are a weather forecast acquisition program, an EPG information acquisition program, a news acquisition program, and a mail acquisition program. In addition, the new arrival information acquisition process A is executed separately and in parallel with the image generation process A.

  Note that initial setting values used in each of the weather forecast acquisition program, the EPG information acquisition program, the news acquisition program, and the mail acquisition program are stored in advance in the nonvolatile memory 142 (or the recording medium 70). As described above, a data table including a plurality of initial setting values is also referred to as an initial setting value table.

  Therefore, the initial setting value table is stored in advance in the nonvolatile memory 142 (or the recording medium 70). In the present embodiment, an initial setting value table T200 described below is stored in advance in the nonvolatile memory 142 (or the recording medium 70).

  FIG. 18 is a diagram illustrating an initial setting value table T200 as an example. Referring to FIG. 18, the initial setting value table T200 is further compared with the initial setting value table T100 of FIG. 7, in addition, information on whether or not to allow PC image enlargement / reduction is set as an initial setting value. It is a table. Further, in the initial set value table T200, in addition to the signal modes of the initial set value table T100, two signal modes corresponding to program numbers 5 and 6 are set. The added signal mode is not limited to two, and may be three or more.

  Each initial setting value in the initial setting value table T200 can be changed in a PC setting image described below.

  The PC setting image 7000 described below is an image displayed on the display unit 280 when the user presses the setting key 346 when the remote controller 300 is in the IT mode.

  FIG. 19 is a diagram showing a PC setting image 7000. Referring to FIG. 19, PC setting image 7000 is different from PC setting image 700 in FIG. 8 in that setting content display area 755 is further arranged. Other than that, it is the same as the PC setting image 700, and the detailed description will not be repeated. In the setting content display areas 710, 720, 730, 740, 750, 755, 762, 764, 772, and 774, initial setting values based on the initial setting value table T200 are displayed.

  The setting content display area 710 is an area for setting a program number. The program number can be set in the range of “1” to “6”. Each time the program number displayed in the setting content display area 710 in the PC setting image 7000 is changed, each setting content display area 720, 730, 740, 750, 755, 762, 764, 772, 774 is displayed. Displays the initial setting value corresponding to the program number in the initial setting value table T200.

  The setting content display area 755 is an area for setting whether to permit enlargement or reduction of the PC image. Accordingly, the setting content in the setting content display area 750 is either “permitted” or “not permitted”.

  The signal modes that can be set in the setting content display area 730 of the PC setting image 7000 are “1366 × 768, 60 Hz”, “1366 × 768, 70 Hz”, “683 × 768, 60 Hz”, “683 × 768, 70 Hz”. In addition, the following two signal modes are added.

  Signal modes to be added are “1024 × 768, 70 Hz” and “1024 × 768, 72 Hz”. The added signal mode is not limited to two, and may be three or more. Further, the added signal mode is not limited to the combination of the image size and the vertical synchronization frequency.

  When the PC setting image 7000 is displayed on the display unit 280, the user can change the initial setting values respectively corresponding to the program numbers 1 to 6 by pressing the remote control 300 in the IT mode. When the user presses the setting key 346 of the remote controller 300 in the IT mode again and the initial setting value is changed, the control unit 120 changes the corresponding initial setting value in the initial setting value table T200. And stored in the nonvolatile memory 142 (or the recording medium 70). Thereafter, the display unit 280 displays an image before the PC setting image 7000 is displayed.

  FIG. 20 is a flowchart of the new arrival information acquisition process A. As an example, a new arrival information acquisition process A performed by the EPG information acquisition program of program number 5 will be described. Referring to FIG. 20, in step S210, information acquisition processing is performed. In the information acquisition process, a process according to the program to be executed is performed. Here, since the program to be executed is an EPG information acquisition program, the following information acquisition process A is performed.

  In the information acquisition process A, the control unit 120 connects to the network 50 and acquires EPG information corresponding to preset area information from a predetermined Internet address (URL). Thereafter, the process proceeds to step S220.

  In step S220, the same process as step S220 of the new arrival information acquisition process of FIG. 9 is performed, and therefore detailed description will not be repeated. If YES in step S220, the process proceeds to step S222. On the other hand, if NO in step S220, the new arrival information acquisition process A ends.

  In step S222, the same process as step S222 of the new arrival information acquisition process of FIG. 9 is performed, and thus detailed description will not be repeated. Thereafter, the process proceeds to step S224.

  In step S224, a process similar to that in step S224 of the new arrival information acquisition process of FIG. 9 is performed, and thus detailed description will not be repeated. If YES at step S224, the process proceeds to step S225. On the other hand, if NO at step S224, the new arrival information acquisition process ends.

  In step S225, it is determined whether enlargement / reduction of the PC image is permitted. Specifically, whether or not the setting content of enlargement / reduction of the PC image of the program corresponding to the new arrival information acquisition process A stored in the nonvolatile memory 142 is “permitted”. Determine. If YES in step S225, the process proceeds to step S225A. On the other hand, if NO at step S225, the process proceeds to step S226.

  In step S225A, the control unit 120 controls the signal mode, the screen mode, the coordinates of the information display area, the size of the information display area, the information acquired in step S210, and the new arrival information acquisition process A corresponding to the new arrival information acquisition process A. A PC image is generated on the basis of various setting values of the program corresponding to.

  When the size of the PC image generated based on the signal mode is 1024 × 768, for example, the control unit 120 once generates an image having a size of 1366 × 768 (hereinafter also referred to as a 1 × magnification image). Then, the control unit 120 generates a PC image obtained by converting the generated equal-size image into an image having a size of 1024 × 768. Thereafter, the process proceeds to step S225B.

  In step S225B, the control unit 120 transmits the PC image signal of the generated PC image to the video output device 200 via the video cable 132. The transmitted PC image signal includes a vertical synchronization signal having a vertical synchronization frequency (for example, 70 Hz) set in correspondence with the program number. Thereafter, the new arrival information acquisition process A ends.

  In steps S226 and S228, the same processes as those in steps S226 and S228 of the newly arrived information acquisition process in FIG. 9 are performed, and thus detailed description will not be repeated. Thereafter, the new arrival information acquisition process A ends.

  The new arrival information acquisition process A described above has been described with respect to the process performed by the EPG information acquisition program corresponding to the program number 5, but the same processes as described above are performed for the program numbers 1 to 6 except for the program number 5. Done.

  In the video output device 200, an image signal reception process A is performed. It is assumed that a TV image 600B shown in FIG. 10B is displayed on the display unit 280 of the video output device 200.

  FIG. 21 is a flowchart of the image signal reception process A. Referring to FIG. 21, in step S510, processing similar to that in step S510 of the image signal reception processing in FIG. 11 is performed, and therefore detailed description will not be repeated. If YES in step S510, the process proceeds to step S520. On the other hand, if NO at step S510, the process at step S510 is performed again.

  In step S520, a process similar to that in step S520 of the image signal reception process of FIG. 11 is performed, and thus detailed description will not be repeated. Thereafter, the process proceeds to step S530.

  In step S530, the control unit 220 determines whether the signal mode based on the combination of the image size determined in step S520 and the determined vertical synchronization frequency is a registered signal mode. Specifically, the control unit 220 determines whether or not the received signal corresponding setting value corresponding to the signal mode based on the combination of the determined image size and the determined vertical synchronization frequency is stored in the nonvolatile memory 242. To do.

  As described above, the data table composed of a plurality of received signal correspondence setting values is a reception signal correspondence setting value table. The received signal correspondence set value table is stored in the nonvolatile memory 242 in advance. In the present embodiment, it is assumed that what is stored in the nonvolatile memory 242 is a reception signal correspondence setting value table T200A described below.

  FIG. 22 is a diagram illustrating a received signal corresponding set value table T200A as an example. Referring to FIG. 22, received signal corresponding set value table T200A corresponds to a signal mode number, signal mode, screen mode, enlargement / reduction permission information or not information, coordinates, height, and width are received signals. It is a table set as a corresponding setting value.

  Each received signal corresponding setting value in the received signal corresponding setting value table T200A can be changed in a TV setting image described below. As described above, the TV setting image is a setting image for setting (changing) a setting value used in a program executed by the video output device 200.

  The TV setting image 7000A described below is an image displayed on the display unit 280 when the user presses the setting key 346 when the remote controller 300 is in the TV mode.

  FIG. 23 is a diagram showing a TV setting image 7000A. Referring to FIG. 23, TV setting image 7000A is different from TV setting image 700A in that setting content display area 755A is further arranged. Other than that, it is the same as TV setting image 700A, and therefore detailed description will not be repeated. In each of the setting content display areas 710A, 730A, 740A, 755A, 762A, 764A, 772A, and 774A, reception signal corresponding setting values based on the reception signal corresponding setting value table T200A are displayed.

  The setting content display area 710A is an area for setting a signal mode number. The signal mode number can be set in the range of “1” to “6”. Each time the signal mode number displayed in the setting content display area 710A is changed, each of the setting content display areas 730A, 740A, 755A, 762A, 764A, 772A, 774A has a received signal corresponding setting value table T200A. The received signal corresponding setting value corresponding to the signal mode number is displayed.

  Since setting content display area 730A is similar to setting content display area 730 of PC setting image 7000, detailed description will not be repeated.

  Since setting content display area 755A is similar to setting content display area 755 of PC setting image 7000, detailed description will not be repeated.

  When TV setting image 7000 </ b> A is displayed on display unit 280, the user can change the reception signal corresponding setting values corresponding to signal mode numbers 1 to 6 by pressing operation of remote controller 300 in the TV mode described above. it can. When the user presses the setting key 346 of the TV mode remote control 300 again, if the received signal correspondence setting value is changed, the control unit 220 changes the corresponding reception in the reception signal correspondence setting value table T200A. The signal corresponding setting value is changed and stored in the nonvolatile memory 242. Thereafter, the display unit 280 displays an image before the TV setting image 7000A is displayed.

  Note that the received signal correspondence setting value table T200A may not be stored in the nonvolatile memory 242 in advance. In this case, the data of the received signal corresponding setting value table T200A is stored in the nonvolatile memory 242 by the following setting data replication processing A.

  FIG. 24 is a flowchart of the setting data replication process A. Referring to FIG. 24, in step S610, a process similar to that in step S610 of the setting data duplication process in FIG. 14 is performed, and thus detailed description will not be repeated. If YES at step S610, the process proceeds to step S620A. On the other hand, if NO at step S610, the process at step S610 is performed again.

  In step S620A, control unit 220 determines whether the data of initial setting value table T200 is recorded on recording medium 70 or not. If YES in step S620A, the process proceeds to step S630A. On the other hand, if NO at step S620A, the process at step S610 is performed again.

  In step S630A, a replication process A is performed. In the replication process A, the control unit 220 accesses the data in the initial setting value table T200 in the recording medium 70. Then, the control unit 220 described the signal mode, the screen mode, the enlargement / reduction permission information or the disallowance information, coordinates, height, and width data corresponding to each execution program number in the initial setting value table T200 as described above. The data is stored in the nonvolatile memory 242 as data of the signal mode, screen mode, enlargement / reduction permission / non-permission, coordinates, height, width corresponding to each signal mode number of the received signal correspondence setting value table T200A. . Thereafter, the setting data replication process A ends.

  With the above processing, the setting data duplication processing A in the present embodiment can achieve the same effects as the setting data duplication processing in FIG.

  Referring to FIG. 21 again, if YES in step S530, the process proceeds to step S540A. On the other hand, if NO at step S530, the process at step S510 is performed again.

  If NO is determined in step S530, that is, if the received PC image signal is not already registered, the control unit 220 displays the PC image based on the received PC image signal in the entire area of the display unit 280. May be displayed.

  In step S540A, a composite image generation process A is performed. In the composite image generation process A, the control unit 220 determines the signal mode of the received PC image signal based on the received signal corresponding setting value table T200A stored in the nonvolatile memory 242. Then, the control unit 220 simultaneously converts the TV image and the PC image based on the screen mode, the enlargement / reduction permission / non-permission information, coordinates, height and width data corresponding to the determined signal mode. The displayed composite image is generated.

  FIG. 25 shows a composite image. FIG. 25A shows a composite image 6000C1 as an example. The composite image 6000C1 is a composite image displayed on the display unit 280 in the PC-in TV mode. An area 6100RA in the composite image 6000C1 is a TV image display area.

  An area 6200RA in the composite image 6000C1 is an information display area. The size of the area 6200RA is 1366 dots wide and 192 dots long. When the enlargement / reduction is permitted, the image in the area 6200RA is an image obtained by reducing the 1366 × 768 size PC image based on the received PC image signal only in the y direction. In area 6200RA, weather information obtained by the processing of the weather information acquisition program is displayed.

  When enlargement / reduction is not permitted, the image in the area 6200RA is an image in the area 6200RA of the PC image having a size of 1366 × 768 based on the received PC image signal by the control unit 220.

  FIG. 25B illustrates a composite image 6000C2 as an example. The composite image 6000C2 is a composite image displayed on the display unit 280 in the TV in PC mode. An area 6100RB in the composite image 6000C2 is a TV image display area. The size of the area 6100RB is 640 dots wide and 480 dots high. The control unit 220 reduces the TV image 600B of FIG. 10B to the size of the region 6100RB. The reduced TV image is displayed in area 6100RB.

  An area 6200RB in the composite image 6000C2 is an information display area. When enlargement / reduction is permitted for the image in the area 6200RB, the control unit 220 enlarges a PC image having a size of 1024 × 768 based on the received PC image signal to a PC image having a size of 1366 × 768 ( Hereinafter, it is also referred to as an enlarged image). A reduced TV image is displayed in area 6100RB in the enlarged image. In area 6200RB, EPG information obtained by the processing of the EPG information acquisition program is displayed.

  When enlargement / reduction is not permitted, the control unit 220 creates, for example, an arbitrary image of 1366 × 768 (for example, full-color black), and has a size of 1024 × 768 based on the received PC image signal at the center. An image obtained by combining the PC images is generated. The reduced TV image is displayed in the area 6100RB.

  FIG. 25C illustrates a composite image 6000C3 as an example. The composite image 6000C3 is a composite image displayed on the display unit 280 in the TV by PC mode. An area 6100RC in the composite image 6000C3 is a TV image display area. The size of the region 6100RC is 683 dots wide and 512 dots long. The control unit 220 reduces the TV image 600B of FIG. 10B to the size of the region 6100RC. The reduced TV image is displayed in the area 6100RC. An area 6200RC in the composite image 6000C3 is an information display area. When enlargement / reduction is permitted for the image in the area 6200RC, the control unit 220 geometrically converts the PC image having a size of 1024 × 768 based on the received PC image signal into a PC image having a size of 683 × 768. It is an image (hereinafter also referred to as a geometric transformation image). In area 6200RC, news information obtained by the processing of the news acquisition program is displayed.

  When enlargement / reduction is not permitted, for example, the control unit 220 protrudes from the right end of the screen with a PC image having a size of 1024 × 768 based on the received PC image signal, starting from the coordinates of (684, 0). Generate an image with the part removed. The reduced TV image is displayed in area 6100RC.

  Referring to FIG. 21 again, when the process of step S540A ends, the process proceeds to step S550.

  In step S550, control unit 220 displays the generated composite image on display unit 280 in a corresponding screen mode (for example, TV-in-PC mode). Thereafter, the process proceeds to step S560.

  Since the processes in steps S560, S570, S572, and S574 are the same as those described above, detailed description thereof will not be repeated.

  Next, the key reception process A performed in step S110A of FIG. 17 will be described. As described above, the key reception process A is executed separately and in parallel with the image generation process A.

  FIG. 26 is a flowchart of the key reception process A. Referring to FIG. 26, in step S111, a process similar to that of step S111 of the key reception process of FIG. 16 is performed, and therefore detailed description will not be repeated. If YES in step S111, the process proceeds to step S112A. On the other hand, if NO at step S111, the process at step S111 is performed again.

  In step S112A, it is determined whether or not the received remote control signal is valid. Specifically, the remote control signal received by the control unit 120 is a remote control signal generated by a user's pressing operation of any one of the numeric keys “1” to “6” in the numeric key group 350 of the IT mode remote control 300. It is determined whether or not.

  If YES in step S112A, the process proceeds to step S113. On the other hand, if NO at step S112A, the process at step S111 is performed again.

  In step S113, the same process as step S113 of the key reception process of FIG. 16 is performed, and thus detailed description will not be repeated. If YES in step S113, the process proceeds to step S114. On the other hand, if NO at step S113, the process at step S111 is performed again.

  In step S115A, it is determined whether enlargement / reduction of the PC image is permitted. Specifically, whether or not the setting content of enlargement / reduction of the PC image of the program corresponding to the new arrival information acquisition process A stored in the nonvolatile memory 142 is “permitted”. Determine. If YES in step S115A, the process proceeds to step S115B. On the other hand, if NO at step S115A, the process proceeds to step S116.

  In step S115B, the control unit 120 executes the signal mode, the screen mode, the coordinates of the information display area, the size of the information display area, the information acquired in step S114, and the new arrival information acquisition process corresponding to the new arrival information acquisition process A. A PC image is generated based on various setting values of the corresponding program. Since the PC image generation method is the same as that described in step S225A of the new arrival information acquisition process A in FIG. 20, detailed description will not be repeated. Thereafter, the process proceeds to step S115C.

  In step S115C, the same processing as in step S225B of FIG. 20 described above is performed, and thus detailed description will not be repeated. Thereafter, the process of step S111 is performed again.

  In step S116, the control unit 120 generates a PC image based on the information acquired in step S114 and various setting values of the program corresponding to the new arrival information acquisition process.

<Third Embodiment>
In the first and second embodiments, in the two-screen display state, the shape of the small image among the PC image and the TV image is limited to a rectangle. In the present embodiment, a process in which the shape of an image having a small size is not limited to a rectangle will be described.

  Note that the video system in the present embodiment is similar to video system 1000 in the first embodiment, and therefore detailed description will not be repeated. In the present embodiment, video signal generation device 100 performs image generation processing B.

  FIG. 27 is a flowchart of the image generation process B. Referring to FIG. 27, image generation process B differs from image generation process of FIG. 6 in that step S110B is performed instead of step S110 and that step S120B is performed instead of step S120. . Other than that, it is the same as the image generation processing, and therefore detailed description will not be repeated.

  In step S110B, key reception processing B is performed. The key reception process B will be described later.

  In step S120B, control unit 120 executes the above-described four new arrival information acquisition programs one by one in order, and performs processing based on each new arrival information acquisition program (hereinafter also referred to as new arrival information acquisition processing B). The four new arrival information acquisition programs may be executed simultaneously in parallel. The four new arrival information acquisition programs are a weather forecast acquisition program, an EPG information acquisition program, a news acquisition program, and a mail acquisition program. In addition, the new arrival information acquisition process A is executed separately and in parallel with the image generation process A.

  Note that initial setting values used in each of the weather forecast acquisition program, the EPG information acquisition program, the news acquisition program, and the mail acquisition program are stored in advance in the nonvolatile memory 142 (or the recording medium 70). As described above, a data table including a plurality of initial setting values is also referred to as an initial setting value table.

  Therefore, the initial setting value table is stored in advance in the nonvolatile memory 142 (or the recording medium 70). In the present embodiment, an initial setting value table T300 described below is stored in advance in the nonvolatile memory 142 (or the recording medium 70).

  FIG. 28 is a diagram illustrating an initial setting value table T300 as an example. Referring to FIG. 28, in comparison with initial setting value table T200, initial setting value table T300 further includes information on permission or non-permission of use of transparent color, R value, G value, and B value of transparent color. It is a table set as an initial setting value.

  Each initial setting value in the initial setting value table T300 can be changed in a PC setting image described below.

  The PC setting image 800 described below is an image displayed on the display unit 280 when the user presses the setting key 346 when the remote controller 300 is in the IT mode.

  FIG. 29 is a diagram showing a PC setting image 800. Referring to FIG. 29, PC setting image 800 is different from PC setting image 7000 in FIG. 19 in that setting content display areas 757, 758A, 758B, and 758C are further arranged. Other than that, it is the same as the PC setting image 7000, and the detailed description will not be repeated. Initial setting values based on the initial setting value table T300 are displayed in the setting content display areas 710, 720, 730, 740, 750, 755, 757, 758A, 758B, 758C, 762, 764, 772, and 774, respectively. ing.

  The setting content display area 710 is an area for setting a program number. The program number can be set in the range of “1” to “6”. Each time the program number displayed in the setting content display area 710 is changed, the setting content display areas 720, 730, 740, 750, 755, 757, 758A, 758B, 758C, 762, 764, 772, 774 Each displays an initial setting value corresponding to a program number in the initial setting value table T300.

  The setting content display area 757 is an area for setting whether to permit the use of a transparent color. Therefore, the setting content in the setting content display area 757 is either “permitted” or “not permitted”.

  The setting content display areas 758A, 758B, and 758C are areas for setting the R value, G value, and B value of the transparent color, respectively, when the use of the transparent color is permitted. The range of numerical values that can be set is a range of “0” to “255”. The numerical value can be set by operating the remote controller 300 in the IT mode, similarly to the setting content display area 762 described above.

  When the use of the transparent color is permitted, the values of the setting content display areas 762, 764, 772, and 774 are not used when the composite image is generated in the video output device 200.

When the PC setting image 800 is displayed on the display unit 280, the user can change the initial setting values respectively corresponding to the program numbers 1 to 6 by pressing the remote control 300 in the IT mode. When the user presses the setting key 346 of the remote controller 300 in the IT mode again, when the initial setting value is changed, the control unit 120 changes the corresponding initial setting value in the initial setting value table T300. And stored in the nonvolatile memory 142 (or the recording medium 70). Thereafter, the display unit 280 displays an image before the PC setting image 800 is displayed.

FIG. 30 is a flowchart of the new arrival information acquisition process B. As an example, a new arrival information acquisition process performed by the weather forecast acquisition program of program number 1 will be described. Referring to FIG. 30, in step S210, a process similar to that in step S210 of the new arrival information acquisition process of FIG. 9 is performed, and thus detailed description will not be repeated. Thereafter, the process proceeds to step S220.

  In step S220, the same process as step S220 of the new arrival information acquisition process of FIG. 9 is performed, and therefore detailed description will not be repeated. If YES in step S220, the process proceeds to step S222. On the other hand, if NO at step S220, the new arrival information acquisition process ends.

  In step S222, the same process as step S222 of the new arrival information acquisition process of FIG. 9 is performed, and thus detailed description will not be repeated. Thereafter, the process proceeds to step S224.

  In step S224, a process similar to that in step S224 of the new arrival information acquisition process of FIG. 9 is performed, and thus detailed description will not be repeated. If YES at step S224, the process proceeds to step S224A. On the other hand, if NO in step S224, the new arrival information acquisition process B ends.

  In step S224A, it is determined whether or not use of a transparent color is permitted. Specifically, the control unit 120 determines whether or not the setting content of the use of the transparent color of the program corresponding to the new arrival information acquisition process B stored in the nonvolatile memory 142 is “permitted”. To do. If YES in step S224A, the process proceeds to step S224B. On the other hand, if NO at step S224B, the process proceeds to step S226.

  In step S224B, the control unit 120 uses the signal mode, screen mode, transparent color R value, G value, B value of the program corresponding to the new arrival information acquisition process B, the information acquired in step S210, and the new arrival information acquisition process B. A PC image is generated on the basis of various setting values of the program corresponding to.

  FIG. 31 is a diagram illustrating an image generated by the video signal generation device 100. FIG. 31A shows a PC image 900 as an example. With reference to FIG. 31A, an area 910R and an area 920R are arranged in the PC image 900. The region 920R is a region other than the region 910R in the PC image 900. The area 910R is an information display area.

  In the area 920R, the transmission color of the designated R value (255), G (255) value, and B (0) value is colored. In the area 910R, information obtained by executing the program corresponding to the new arrival information acquisition process is displayed.

After the process of step S224B, the process proceeds to step S224C.
In step S224C, the control unit 120 transmits the generated PC image signal of the PC image to the video output device 200 via the video cable 132. The transmitted PC image signal includes a vertical synchronization signal having a vertical synchronization frequency (for example, 60 Hz) set corresponding to the program number. Thereafter, the new arrival information acquisition process B ends.

  In steps S226 and S228, the same processes as those in steps S226 and S228 of the newly arrived information acquisition process in FIG. 9 are performed, and thus detailed description will not be repeated. Thereafter, the new arrival information acquisition process B ends.

  In addition, although the above-mentioned new arrival information acquisition process B demonstrated the process performed by the weather forecast acquisition program corresponding to the program number 1, the process similar to what was mentioned above is performed also about the program numbers 2-6.

  In the video output device 200, an image signal reception process B is performed. It is assumed that a TV image 600B shown in FIG. 10B is displayed on the display unit 280 of the video output device 200.

  FIG. 32 is a flowchart of the image signal reception process B. Referring to FIG. 32, in step S510, a process similar to that in step S510 of the image signal reception process in FIG. 11 is performed, and thus detailed description will not be repeated. If YES in step S510, the process proceeds to step S520. On the other hand, if NO at step S510, the process at step S510 is performed again.

  In step S520, a process similar to that in step S520 of the image signal reception process of FIG. 11 is performed, and thus detailed description will not be repeated. Thereafter, the process proceeds to step S530.

  In step S530, the control unit 220 determines whether the signal mode based on the combination of the image size determined in step S520 and the determined vertical synchronization frequency is a registered signal mode. Specifically, the control unit 220 determines whether or not the received signal corresponding setting value corresponding to the signal mode based on the combination of the determined image size and the determined vertical synchronization frequency is stored in the nonvolatile memory 242. To do.

  As described above, a data table composed of a plurality of received signal correspondence setting values is a reception signal correspondence setting value table. The received signal correspondence set value table is stored in the nonvolatile memory 242 in advance. In the present embodiment, it is assumed that what is stored in the nonvolatile memory 242 is a reception signal correspondence setting value table T300A described below.

  FIG. 33 is a diagram illustrating a received signal corresponding set value table T300A as an example. Referring to FIG. 33, the received signal correspondence set value table T300A corresponds to the signal mode number, signal mode, screen mode, enlargement / reduction permission / non-permission information, permission / non-permission of use of transparent color. Information, R value, G value, B value, coordinates, height, and width of the transparent color are set as reception signal corresponding setting values.

  Note that each received signal corresponding setting value in the received signal corresponding setting value table T300A can be changed in a TV setting image described below. As described above, the TV setting image is a setting image for setting (changing) a setting value used in a program executed by the video output device 200.

  The TV setting image 800A described below is an image displayed on the display unit 280 when the user presses the setting key 346 when the remote controller 300 is in the TV mode.

  FIG. 34 shows a TV setting image 800A. Referring to FIG. 34, TV setting image 800A is different from TV setting image 7000A in FIG. 23 in that setting content display areas 757A, 758AA, 758BA, and 758CA are further arranged. Other than that, it is the same as TV setting image 7000A, and therefore detailed description will not be repeated. In each of the setting content display areas 710A, 730A, 740A, 755A, 757A, 758AA, 758BA, 758CA, 762A, 764A, 772A, and 774A, received signal corresponding setting values based on the received signal corresponding setting value table T300A are displayed. ing.

  The setting content display area 710A is an area for setting a signal mode number. The signal mode number can be set in the range of “1” to “6”. Each time the signal mode number displayed in the setting content display area 710A is changed, each of the setting content display areas 730A, 740A, 755A, 757A, 758AA, 758BA, 758CA, 762A, 764A, 772A, 774A The received signal corresponding setting value corresponding to the signal mode number in the received signal corresponding setting value table T300A is displayed.

  Since the setting content display area 757A is similar to the setting content display area 757 of the PC setting image 800, detailed description will not be repeated.

  When the use of the transparent color is permitted, the values of the setting content display areas 762A, 764A, 772A, and 774A are not used when the composite image is generated in the video output device 200.

  Since the setting content display areas 758AA, 758BA, and 758CA are the same as the setting content display areas 758A, 758B, and 758C of the PC setting image 800, detailed description will not be repeated.

  When the TV setting image 800A is displayed on the display unit 280, the user can change the reception signal corresponding setting values corresponding to the signal mode numbers 1 to 6 by pressing the remote control 300 in the TV mode described above. it can. When the user again presses the setting key 346 of the TV mode remote controller 300, if the received signal corresponding setting value is changed, the control unit 220 receives the corresponding received signal in the received signal corresponding setting value table T300A. The signal corresponding setting value is changed and stored in the nonvolatile memory 242. Thereafter, the display unit 280 displays an image before the TV setting image 800A is displayed.

  The reception signal corresponding setting value table T300A may not be stored in the nonvolatile memory 242 in advance. In this case, the data of the received signal corresponding setting value table T300A is stored in the nonvolatile memory 242 by the following setting data replication processing B.

  FIG. 35 is a flowchart of the setting data replication process B. Referring to FIG. 35, in step S610, a process similar to that in step S610 of the setting data copying process in FIG. 14 is performed, and thus detailed description will not be repeated. If YES in step S610, the process proceeds to step S620B. On the other hand, if NO at step S610, the process at step S610 is performed again.

  In step S620B, control unit 220 determines whether or not data of initial setting value table T300 is recorded on recording medium 70. If YES at step S620B, the process proceeds to step S630B. On the other hand, if NO at step S620B, the process at step S610 is performed again.

  In step S630B, duplication processing B is performed. In the duplication process B, the control unit 220 accesses data in the initial setting value table T300 in the recording medium 70. Then, the control unit 220 corresponds to each execution program number of the initial setting value table T300, the signal mode, the screen mode, the enlargement / reduction permission / non-permission information, the transparent color use permission / non-permission information, The R, G, B, coordinates, height, and width data of the transparent color are set to the signal mode, screen mode, and enlargement / reduction corresponding to each signal mode number in the received signal correspondence setting value table T300A. Information on permission or non-permission, information on permission or non-permission of use of the transparent color, R value, G value, B value, coordinate, height, and width data of the transparent color is stored in the nonvolatile memory 242. Thereafter, the setting data replication process B ends.

  With the above processing, the setting data replication process B in the present embodiment can achieve the same effects as the setting data replication process of FIG.

  Referring to FIG. 32 again, if YES in step S530, the process proceeds to step S540B. On the other hand, if NO at step S530, the process at step S510 is performed again.

  In step S540B, a composite image generation process B is performed. In the composite image generation process B, the control unit 220 determines the signal mode of the received PC image signal based on the received signal corresponding setting value table T300A stored in the nonvolatile memory 242. Then, when the information on the use of the transparent color corresponding to the determined signal mode is “permitted”, the control unit 220 displays the screen mode, the enlargement / reduction permission information or the disapproval information corresponding to the determined signal mode, and Based on the R value, G value, and B value of the transmitted color, a composite image in which the TV image and the PC image are simultaneously displayed is generated. That is, the control unit 220 does not use the coordinate, height, and width data when generating the composite image.

  Referring to FIG. 31 again, FIG. 31 (B) is a diagram showing a composite image 900C as an example. The composite image 900C is a composite image displayed on the display unit 280 in the PC-in TV mode. An area 920R in the composite image 900C is a TV image display area. In the area 920R, for example, a TV image in an area corresponding to the area 920R in the TV image 600B in FIG. 10B is displayed. Therefore, the control unit 220 generates an image in which the TV image is displayed on the pixel portion having the R value (255), G value (0), and B value (0) of the specified transparent color in the PC image 900. To do.

  An area 910R in the composite image 900C is an information display area. The shape of the region 910R is an ellipse. The shape of the region 910R is not limited to an ellipse, and may be any shape (for example, a star shape) as long as it is a shape other than a rectangle. In the area 910R, weather information obtained by the processing of the weather information acquisition program is displayed.

  By displaying the composite image 900C as described above on the display unit 280, a PC image having a shape other than a rectangle can be overlaid on the TV image.

  On the other hand, when the information on the use of the transparent color corresponding to the determined signal mode is “non-permitted”, the control unit 220 displays information regarding the screen mode, enlargement / reduction permission or disapproval corresponding to the determined signal mode. Based on the coordinate, height and width data, a composite image in which the TV image and the PC image are simultaneously displayed is generated. In this case, the generated composite image is, for example, the composite image 6000C1, the composite image 6000C2, or the composite image 6000C3 in FIG.

  Referring to FIG. 32 again, when the process of step S540B ends, the process proceeds to step S550.

  In step S550, control unit 220 displays the generated composite image on display unit 280 in a corresponding screen mode (for example, PC-in-TV mode). Thereafter, the process proceeds to step S560.

  Since the processes in steps S560, S570, S572, and S574 are the same as those described above, detailed description thereof will not be repeated.

  Next, the key reception process B performed in step S110B of FIG. 27 will be described. As described above, the key reception process B is executed separately and in parallel with the image generation process B.

  FIG. 36 is a flowchart of the key reception process B. Referring to FIG. 36, in step S111, the same process as step S111 of key reception process A of FIG. 26 is performed, and therefore detailed description will not be repeated. If YES in step S111, the process proceeds to step S112A. On the other hand, if NO at step S111, the process at step S111 is performed again.

  In step S112A, the same process as step S112A of key reception process A in FIG. 26 is performed, and therefore detailed description will not be repeated. If YES in step S112A, the process proceeds to step S113. On the other hand, if NO at step S112A, the process at step S111 is performed again.

  In step S113, the same processing as step S113 of key reception processing A in FIG. 26 is performed, and thus detailed description will not be repeated. If YES in step S113, the process proceeds to step S114. On the other hand, if NO at step S113, the process at step S111 is performed again.

  In step S114, the same processing as step S114 of key reception processing A in FIG. 26 is performed, and therefore detailed description will not be repeated. Thereafter, the process proceeds to step S114A.

  In step S114A, processing similar to that in step S224A in FIG. 30 is performed, and thus detailed description will not be repeated. If YES in step S114A, the process proceeds to step S114B. On the other hand, if NO at step S114A, the process proceeds to step S116.

  In step S114B, control unit 120 generates a PC image by the same processing as in step S224B of FIG. Thereafter, the process proceeds to step S114C.

  In step S114C, processing similar to that in step S224C in FIG. 30 is performed, and thus detailed description will not be repeated. Thereafter, the process of step S111 is performed again.
