It is possible to do.

<3. Wide Mode Display Example of the Present Embodiment> Next, a wide mode display example of the present embodiment will be described with reference to FIGS. In the set-top box 1 of the present embodiment, as described above, the aspect ratio changeover switch 20 supports the normal mode in which the RGB signal is output based on the resolution corresponding to the 4: 3 aspect ratio and the 16: 9 aspect ratio. Switching to the wide mode for outputting RGB signals based on the resolution to be performed is enabled. By the way, the graphic display standard of the set-top box 1 related to the following description,
For the normal mode (corresponding to 4: 3 aspect ratio), a well-known VGA (Video Graphic A
rray) and SVGA (Super-VGA). For the wide mode (corresponding to a 16: 9 aspect ratio) which is a feature of the present embodiment, as described later, a 16: 9 aspect ratio is defined based on SVGA defined as having higher resolution than VGA. The resolution (the number of pixels) corresponding to the ratio is set.

FIG. 4 shows the specifications of the normal mode and the wide mode in this embodiment. Here, as the normal mode, VGA: 640 × 480
(= Number of horizontal pixels × number of vertical pixels) and SVGA: 800 ×
600 are listed. And VGA: 640 × 4
As a specification of 80, a pixel frequency: 25.125 MH
z, horizontal scanning frequency: 31.4688 KHz, vertical scanning frequency: 59.4905 Hz. Also, SV
The specifications of GA: 800 × 600 include a pixel frequency of 4
9.500 MHz, horizontal scanning frequency: 46.875 KH
z, vertical scanning frequency: 75,000 Hz.

As the wide mode of the present embodiment, two modes having different resolutions are provided as shown in the figure. One wide mode is referred to as "WIDE-1", and the other wide mode having a higher resolution is referred to as "WIDE-2".
The WIDE-1 has a resolution of 848 × 480 (the number of horizontal pixels × the number of vertical pixels), and the pixel frequency is 33.3.
57 MHz. Also, horizontal scanning frequency: 3
1.4688 KHz, vertical scanning frequency: 59.4905
Hz. Also, WIDE-2 is 1060 × 6
00, the pixel frequency is 65.588 MH
z. Horizontal scanning frequency: 31.468
8 KHz, vertical scanning frequency: 59.9405 Hz.

According to the above specification, WIDE-1: 848
× 480 and VGA: 640 × 480, and WIDE-
The vertical resolution (the number of vertical pixels) is the same for each set of 2: 1060 × 600 and SVGA: 800 × 600. That is, WIDE-1: 848 × 480 is equal to V
After having the same level of resolution as GA: 640 × 480, the number of horizontal pixels is expanded corresponding to 16: 9, and WIDE-
2: 1060 × 600 has the same level of resolution as SVGA: 800 × 600, and the horizontal pixel number corresponding to 16: 9 is set.

When the pixel frequency, the horizontal scanning frequency, and the vertical scanning frequency are viewed, WIDE-1: 84
In the case of 8 × 480, the horizontal scanning frequency and the vertical scanning frequency have the same specifications as VGA: 640 × 480, and the pixel frequencies are different depending on the number of pixels in the horizontal direction.
Similarly, if WIDE-2: 1060 × 600, S
VGA: The horizontal scanning frequency and vertical scanning frequency have the same specifications as 800 × 600, and the pixel frequencies are set to be different.

That is, when scanning for wide mode display is performed on the monitor device, the horizontal / vertical scanning frequency may be the same as in the normal mode (VGA or SVGA).

Next, the above WIDE-1 and WIDE-2
A method of setting the number of pixels (resolution) as will be described with reference to FIGS. As the SVGA, in addition to SVGA: 800 × 600 shown in FIG. 3, higher resolution SVGA: 1024 × 768, SVGA: 1280 × 1
024 etc. are defined. Therefore, in the present embodiment, these high-resolution SVGAs: 1024 × 768,
SVGA: WIDE- using 1280 × 1024
It is configured to set the number of pixels of 1 and WIDE-2. The above SVGA: 1024 × 768, SVG
A: 1280 × 1024 also sets the number of horizontal / vertical pixels corresponding to an aspect ratio of 4: 3.

FIG. 5 shows the number of pixels (resolution) of WIDE-1.
As a setting example, a case based on SVGA: 1024 × 768 is shown. According to this, SVGA: 1024
By taking 848 pixels in the horizontal direction and 480 pixels in the vertical direction on the mapping of the pixel data as x768, the resolution as WIDE-1: 848x480 can be set.

In the case of WIDE-2, SV
On the mapping of pixel data as GA: 1280 × 1024, by taking 1060 pixels in the horizontal direction and taking 600 pixels in the vertical direction, WIDE-2: 1060
A resolution of × 600 can be set.

When image data in the wide mode is actually created, in the case of WIDE-1, for example, an image processing area corresponding to SVGA: 1024 × 768 in the VRAM in the video processor 11 is set. Once formed, WIDE-1: 848 shown in FIG.
By performing the image data processing so that the memory write / read processing is executed only for the area of × 480, image data based on WIDE-1: 848 × 480 can be obtained. The same applies to the case of WIDE-2. An image processing area corresponding to SVGA: 1024 × 768 is formed in the VRAM, and the WID shown in FIG.
E-2: Image data processing is performed using only the 1060 × 600 area.

The WID thus formed is
E-1: 848 × 480 or WIDE-2: 1060
The video processor 11 performs required signal processing on the image data of × 600, and outputs the RGB data together with the horizontal / vertical scanning frequency signals represented by the numerical values shown in FIG.
Image display with an aspect ratio of 6: 9 is performed.

According to such an aspect ratio conversion (resolution change setting) method, WIDE-1: 848 × 480.
And WIDE-2: 1060 × 600 are both set based on SVGA. Therefore, in a display control system for an existing VGA, software is installed so that the video processing operation as shown in FIGS. 5 and 6 can be realized. What is necessary is just to configure. That is, in the present embodiment, it is possible to use the existing display control configuration corresponding to VGA and SVGA as hardware.

In the present embodiment, for example, a resolution of 16: 9 aspect ratio is selected by the aspect ratio switch 20, and an image supplied from the medium selected in the set-top box 1 has a 4: 3 aspect ratio. If the image is based on the corresponding resolution (for example, a VGA image), an image having a resolution of 16: 9 aspect ratio is composed of a 4: 3 aspect ratio image of the selected medium and a GUI image such as a menu screen. It is possible to display. In this case, the image displayed on the monitor device 2 based on the RGB signal output of the set-top box 1 is as shown in FIG.

FIG. 7 is a diagram showing an example of a display image having a resolution of 16: 9 aspect ratio. As shown,
For example, an image (4: 3 aspect ratio) of the medium selected in the set-top box 1 is displayed by setting the first area on the left side of the screen, for example, as a 4: 3 area, and for example, the right side which is other than the 4: 3 area A menu screen in which various operation items and the like for an image displayed in, for example, a 4: 3 area is displayed as an icon using the second area as a GUI area. That is, the whole image obtained with the resolution of 16: 9 aspect ratio is formed and displayed by the 4: 3 area and the GUI area. Here, V
An example is shown in which a movie or the like is viewed by selecting an video-CD, a network, or the like.
A menu screen for performing an operation (for example, playback, fast forward, fast rewind, pause, etc.) corresponding to the video-CD or the network is displayed.

As shown in FIG. 7, in order to form a 16: 9 image area with a 4: 3 area and a GUI area, for example, W
IDE-1: After setting an image processing area corresponding to a resolution (number of pixels) of 848 × 480, a predetermined area occupying 600 × 480 horizontal / vertical pixels on this image processing area is : Data writing control is performed by mapping image data as three areas. A GUI for an area occupying the remaining number of horizontal / vertical pixels 248 × 480 on the image processing area
Data writing control is performed by mapping GUI image data as an area. Then, the image data on the image processing area obtained in this way is sequentially read out, for example, for each horizontal line (in this case, data for one horizontal line = 848 pixels), and this readout is performed. An image signal is formed based on the data. By performing display based on this image signal, display in a form as shown in FIG. 7 is realized.

In FIG. 7, as an example, a movie image supplied from a medium such as a Video-CD or a network is displayed in a 4: 3 area, and functions such as reproduction and stop corresponding to the movie are displayed in a GUI area. Although an example in which the menu screen displayed as an icon is displayed has been described, as a general concept in the present embodiment, a menu screen corresponding to a medium playing an image displayed in the 4: 3 area is displayed. You should do it. Further, for example, the menu screen displayed in the GUI area can be switched so that not only the menu screen for operating the currently selected medium as shown in the figure but also the set top box 1 is displayed.
A menu screen for operating itself may be displayed.

Although WIDE-1 has been described with reference to FIG. 7, even when WIDE-2 shown in FIG. 6 is set, it is assumed that the resolution is 1060 × 600 and the above description is followed. 4: 3 area and GUI area are V
By arranging it on the image processing area in the RAM,
An image having a 16: 9 aspect ratio resolution image displayed in the same form as that shown in FIG. 7 can be formed.

<4. Processing Operation When Displaying GUI Image> Hereinafter, according to the flowchart shown in FIG.
16: 9 depending on 4: 3 area and GUI area shown in
The processing operation when forming and displaying an image having an aspect ratio resolution will be described. This flowchart is shown as an example that is executed when the resolution of the 16: 9 aspect ratio is selected by the aspect ratio switch 20.

First, when a medium (for example, a Video-CD, a network) to be played back on the set-top box 1 is selected by the remote commander RC and the operation unit 19 (S001), the selected medium has any aspect ratio. It is determined whether an image is to be formed in a format having a resolution based on the image (S002). The aspect ratio discrimination processing in step S002 is performed by setting the aspect ratio (resolution mode) preset for each medium (for example, a movie or the like) selected in step S001.
Therefore, it is determined. If it is determined in step S002 that the selected medium forms an image with a 4: 3 aspect ratio, the image data of the selected medium (hereinafter, referred to as selected image data) is stored in, for example, a VRAM in the video processor 11. (S003). Further, GUI image data for constructing a menu screen for performing various operations corresponding to the medium is read from the ROM 13 and stored in the VRAM (S004).

When the selected image data and the GUI image data are RA
When the data is stored in the M14, the data is combined for each horizontal line, and a process of reading out the image data with a resolution of 16: 9 aspect ratio is performed (S005). This is because, as described earlier with reference to FIG. 7, the selected image data is read from the first pixel to the 640th pixel of one horizontal line, that is, in the 4: 3 area, and the subsequent 641th pixel to the 848th pixel are selected. That is, in the GUI area, the GUI image data is read out to form output image data having a resolution of 16: 9 aspect ratio composed of 848 pixels per horizontal line. Then, the output image data read from the RAM 14 is output by the video processor 11 as an RGB signal or a video signal (S006). As a result, as shown in FIG. 7, a GUI image as a menu screen for performing various operations on the medium can be displayed together with the image of the selected medium.

In step S002, if a resolution of 16: 9 aspect ratio is selected,
When a medium forming an image with an aspect ratio is selected, the image of the medium may be displayed as it is in the entire display area having a 16: 9 aspect ratio. In this case, the menu screen based on the GUI image may be displayed by switching to the image being displayed as necessary, or may be superimposed on a part of the displayed image.

As described above, in the present embodiment, when the aspect ratio changeover switch 20 selects a resolution of, for example, a 16: 9 aspect ratio and further selects a medium for forming a display image with a 4: 3 aspect ratio, 16: 9
By effectively utilizing the display area of the aspect ratio display unit, an image of the selected medium and a GUI image as a menu screen for performing various operations on the selected medium can be simultaneously displayed. In this case, the media image can also be displayed in a normal aspect ratio (for example, 4: 3), so that it can be displayed in a good condition. Further, the menu screen is displayed in a different area from the media image. Therefore, various operations can be performed without hindering the user's viewing.

In this embodiment, when the monitor device 2 having the display section of the 16: 9 aspect ratio is used and the medium for forming the image with the resolution of the 4: 3 aspect ratio is selected. However, for example, when a monitor device having a display unit having a 4: 3 aspect ratio is used, and a medium for forming an image with a resolution of 16: 9 aspect ratio is selected. , A 16: 9 aspect ratio media image may be displayed at a regular aspect ratio, and a menu screen for performing various operations on the media may be displayed in other areas.

[0047]

As described above, according to the present invention, for example, a display area having a resolution of 16: 9 aspect ratio is divided into a 4: 3 area for displaying an image having a resolution of 4: 3 aspect ratio, and
It is configured so that display control for configuring a GUI area for displaying a GUI image, such as a menu screen, in an area other than the 4: 3 area can be performed.
Therefore, for example, when a monitor device having a display unit with a 16: 9 aspect ratio is used and a medium for forming and displaying an image with a 4: 3 aspect ratio is selected for this monitor device and reproduced. In addition, an image of the medium can be displayed in a 4: 3 area with a regular aspect ratio, and a menu screen for performing operation control of the medium can be displayed as a GUI image in a GUI area. Thus, even when various operations are performed on the menu screen while viewing an image having a 4: 3 aspect ratio, the menu screen is switched from the image or the menu screen is superimposed on a part of the image and displayed. Since it is not necessary, the viewing is not interrupted. Further, even when using the function of performing an operation while viewing an image, the menu screen is displayed in a GUI area different from the image, so that the operation can be performed in accordance with the displayed image, and the operability is improved. There is an advantage of improving.

IDE-1: After setting an image processing area corresponding to a resolution (number of pixels) of 848 × 480, a predetermined area occupying 640 × 480 horizontal / vertical pixels on this image processing area : Data writing control is performed by mapping image data as three areas. Then, the remaining horizontal / vertical on the image processing area
GUI for area occupying 208 × 480 direct pixels
Data writing control is performed by mapping GUI image data as an area. Then, the image data on the image processing area obtained in this way is sequentially read out, for example, for each horizontal line (in this case, data for one horizontal line = 848 pixels), and this readout is performed. An image signal is formed based on the data. By performing display based on this image signal, display in a form as shown in FIG. 7 is realized.
