  The program storage unit 17 stores a screen display program PRG1 shown in FIG.

  The screen position information storage unit 18 stores display position information of the video 20 displayed on the display 16. For example, as shown in FIG. 3, when two images 20 (20A, 20B) are displayed on the display 16 at the same time, for one image 20A (left side in FIG. 3), the coordinates (X1 , Y1) and the coordinates (X2, Y2) of the lower right vertex, and for the other image 20B (right side in FIG. 3), the coordinates of the upper left vertex (X3, Y3) and the coordinates of the lower right vertex ( X4, Y4) are stored.

  In addition, the remote control signal receiver 19 has a function of receiving a signal from the remote controller 13 and outputting it to the CPU 9.

  Furthermore, the remote controller 13 includes buttons (not shown) for various controls of the television receiver 1 and, as shown in FIG. 1, an operation switching button 13a for specifying an active video, OSD (here, An OSD display button 13b for displaying a menu display is provided below.

  Since the television receiver 1 has the above-described configuration, as shown in FIG. 3, when two images 20A and 20B are simultaneously displayed on the display 16, that is, when two images are simultaneously displayed, the user Each time the (viewer) presses the operation switching button 13a of the remote controller 13, the two images 20A and 20B are alternately activated. That is, for example, when one video 20A is active (the other video 20B is inactive (inactive)), pressing the operation switching button 13a once activates the other video 20B (one video 20A is When the operation switching button 13a is further pressed once, one video 20A returns to active (the other video 20B is inactive). Since the active / inactive switching of the video 20 is instructed by the CPU 9 to the video display state management unit 6 based on a signal from the remote controller 13, the video display state management unit 6 determines which video 20 is active. Always recognize. Here, the active video 20 means a video specified by the operation switching button 13a as a target video that can be adjusted such as video and audio on the multiple video display screen.

  When a menu is displayed on the display 16 in a state where any one of the images 20 (for example, 20A) is active, the user presses the OSD display button 13b of the remote controller 13. Then, an OSD display signal is output from the remote controller 13 and input to the CPU 9 via the remote controller signal receiver 19. In response to this, the CPU 9 reads the screen display program PRG1 shown in FIG. 2 from the program storage unit 17, and executes the screen display operation based on the screen display program PRG1 according to the procedure described below.

  First, the CPU 9 instructs the video display state management unit 6 to determine whether the video 20 is active. In response to this, the video display state management unit 6 determines which video 20 is active (step S1). For example, when the video 20A is active, the video display state management unit 6 determines that the video 20A is active. When the video 20B is active, the video display state management unit 6 determines that the video 20B is active.

  Next, the CPU 9 instructs the video display position management unit 7 to acquire the position information of the active video 20. In response to this, the video display position management unit 7 reads out and acquires the position information of the active video 20 from the screen position information storage unit 18 (step S2). For example, when the video 20A is active, the video display position management unit 7 determines the position information of the video 20A, specifically, the coordinates (X1, Y1) of the upper left vertex of the rectangle and the coordinates (X2, Y2) of the lower right vertex. ) To get.

  Next, the CPU 9 instructs the video display position management unit 7 to determine the margin position on the screen for the active video 20. In response to this, the video display position management unit 7 determines a margin position on the screen for the active video 20 based on the position information of the active video 20 (step S3). That is, as shown in FIG. 4, the video display position management unit 7 in the horizontal direction is a distance L1 from the upper left of the active video 20 to the left end of the display 16 and the lower right of the active video 20 from the lower right of the display 16. The distance L2 to the right end is calculated, and these distances L1 and L2 are compared with each other to determine the larger lateral region. In the vertical direction, a distance L3 from the upper left of the active video 20 to the upper end of the display 16 and a distance L4 from the lower right of the active video 20 to the lower end of the display 16 are calculated, and these distances L3, L4 is compared with each other to determine the larger vertical region. Then, by combining the horizontal direction and the vertical direction, it is determined that there is a margin position on the screen for the active video 20 in any one of the upper left, upper right, lower left, and lower right areas of the display 16. For example, when the distance L2 in the horizontal direction is larger than the distance L1 (L1 <L2) and the distance L3 is larger than the distance L4 in the vertical direction (L4 <L3), the active video 20 is displayed in the upper right area of the display 16. It is determined that there is a margin position on the screen for.

  Next, the CPU 9 determines an arrangement position of the menu display 21 for setting video or audio based on the determination result (step S4). For example, when there is a margin position on the screen for the active video 20 in the upper right area of the display 16, the CPU 9 determines the upper right area of the display 16 as the arrangement position of the menu display 21.

  Finally, the CPU 9 reads out OSD information corresponding to the operation command from the remote controller 13 from the OSD information storage unit 10 and outputs it to the OSD display unit 11 together with the display position information. The video composition processing unit 12 synthesizes the video output from the video / audio output unit 5 and the menu display information from the OSD display unit 11 and outputs them to the display 16 (step S5). As a result, the menu display 21 is OSD-displayed on the display 16 at the active image and the margin position for the active image.

  At this time, the menu display 21 is OSD-displayed at a predetermined arrangement position on the display 16, that is, a margin position with respect to the active image, and therefore does not overlap with the active image 20. For example, when one video 20A is active, the menu display 21 does not overlap with this active video 20A as shown in FIG. When the other video 20B is active, the menu display 21 does not overlap with this active video 20B as shown in FIG.

  Thus, since the menu display 21 does not overlap with the active video 20, it is possible to avoid a situation where the active video 20 is hidden behind the menu display 21. Therefore, the user can easily perform the setting operation on the menu display 21 while viewing the active video 20, and usability is improved. Such improvement in usability is particularly useful when setting items to be determined while viewing the active video 20 (for example, brightness, hue, contrast, etc. of the active video 20).

  Here, the screen display operation based on the screen display program PRG1 ends.

<Other embodiments>
In the above-described embodiment, the case where the menu display 21 is OSD-displayed while avoiding overlapping with the active video 20 that is the operation target has been described. However, when the OSD display of the menu display 21 is performed, FIG. As described above, it is possible not only to avoid the overlap with the active image 20A but also to overlap the inactive image 20B that is not the operation target. In this case, the CPU 9 arranges the menu display 21 so as to overlap the inactive video 20B while avoiding overlapping with the active video 20A based on the position information of the active video 20A and the inactive video 20B. Determine the position. Then, since the inactive video 20B is hidden behind the menu display 21, it becomes clear which of the two videos 20A and 20B is active, and usability is further improved.

  In the above-described embodiment, two video screen simultaneous display has been described as an example of multi video screen display. However, multi video screen display other than two video screen simultaneous display (for example, four video screen simultaneous display, nine video screens, etc.) Of course, the present invention can be similarly applied to simultaneous display and the like.

  In the above-described embodiment, the setting menu display 21 has been described as the OSD. However, the OSD is not limited to the setting menu display 21. For example, it may be for channel number display, setting confirmation such as an on-timer, off-timer, recording reservation, or related information or EPG of the active video 20.

  In the above-described embodiment, the television receiver 1 has been described as an example of the video display device. However, the television receiver 1 has a function of simultaneously displaying a plurality of videos 20 on the display 16 and an OSD function. As long as the present invention is applicable, the present invention can be similarly applied to video display devices other than the television receiver 1 (for example, media players, portable AV players, personal computers, game machines, mobile phones, etc.).
