However, the image for high definition is
Since the resolution is high, the amount of information is large accordingly, and there is a problem that the hardware configuration becomes large in order to construct a multimedia system using high-definition. For example, in a commercially available MUSE type optical disk device, since the reproduction time of one optical disk is about 30 minutes, it is necessary to prepare a plurality of devices in order to perform a demonstration for a longer time. .

[0006] Therefore, an object of the present invention is to provide a multimedia information presenting apparatus capable of presenting information efficiently with a hardware configuration as small as possible.

It is a device that has the function of reproducing. A feature of the present invention is that a window area is defined in a part of a high resolution reproduced image, and a low resolution reproduced image is combined and displayed in the window area. In other words, the high-definition image of the high-definition system is used as the background image, and the low-resolution image of the NTSC system is displayed only in the specific window area in the background image. Here, if a still image is used as a background high-definition image and a moving image is used as an NTSC image in the window area, it is possible to present a moving screen as a whole, and It can give the impression of a high-quality screen.

In addition, it is possible to easily create a program for performing such control.

[0015]

The present invention will be described below based on illustrated embodiments. FIG. 1 is a block diagram showing the basic configuration of a multimedia information presentation device according to an embodiment of the present invention. Here, as a device with the function of playing images and sounds,
There are four devices, a high-definition optical disk device 10a, NTSC optical disk devices 10b and 10c, and a reproducing personal computer 10d. The high-definition optical disk device 10a is a commercially available player having a function of reproducing high-definition images and audio from an optical disk recorded by the MUSE compression method, and one optical disk can record 30 minutes of moving images.
On the other hand, the NTSC optical disk devices 10b and 10c are both used to record NTS from an optical disk recorded by the NTSC system.
It is a commercially available player having a function of reproducing C image and sound, and also one optical disk can record a moving image of 30 minutes. Although two NTSC optical disk devices are provided in this embodiment, only one NTSC optical disk device may be provided, or three or more NTSC optical disk devices may be provided. Also, two or more high-definition optical disk devices may be provided,
As will be described later, the image reproduced by the high-definition optical disk device is used as a background image, and therefore there is not much merit in providing two or more devices. The reproduction personal computer 10d is a commercially available personal computer in which general multimedia reproduction software is installed. By operating this software, moving images, still images, characters, figures, graphs, Information such as voice can be created and output. In addition, an audio C is provided in the reproducing personal computer 10d.
A CD drive device for reproducing D and a hard disk device are built in.

The image signals Va to Vd reproduced by these four reproducing devices 10a to 10d are converted into image signals by the image synthesizing device 1.
Given to 1. The image synthesizing device 11 includes an input terminal I0 for inputting a high-definition image signal and an NTSC.
There are three input terminals: an input terminal I1 for inputting the image signal of the method and an input terminal I2 for inputting the image signal from the reproduction personal computer 10d. Therefore, the image signal Va output from the high-definition optical disk device 10a is given to the input terminal I0, and the image signals Vb and Vc output from the NTSC optical disk devices 10b and 10c.
Only one of them is given to the input terminal I1 via the switch 12, and the reproduction personal computer 10
The image signal Vd output by d is given to the input terminal I2. The switching device 12 receives the image signal V based on the switching signal S.
It has a function of selecting and outputting either b or Vc.

The image synthesizing device 11 synthesizes the given image signals by the method described later and gives the created synthesized image to the signal converter 13. The signal converter 13 performs a process of converting the composite image supplied from the image composition device 11 into a YPbPr signal because the composite image is an RGB signal. On the other hand, in the high-definition character generator 14, as will be described later, an image of the mouse cursor is created and this is the YPbP
It is output in the form of r signal. Superimposing device 15
Has a function of superimposing the signal from the signal converter 13 and the signal from the high-definition character generation device 14 to create a signal by superimposing the images of both signals and giving the signal to the high-definition monitor 16. In this way, the mouse cursor created by the high-definition character generation device is superimposed on the combined image combined by the image combining device 11 and displayed on the display screen of the high-definition monitor 16. The flow of the image signal has been described above. In FIG. 1, the path of the image signal is shown by a solid line.

On the other hand, the flow of the audio signal takes the following route as shown by the alternate long and short dash line in FIG. That is, the audio signals Aa to Ad reproduced by the four reproducing devices 10 a to 10 d are given to the speech synthesizer 21. The voice synthesizer 21 is a so-called commercially available voice mixer, and has a function of superimposing four voice signals Aa to Ad and giving the superimposed voice signals to the speaker 22. Therefore, from the speaker 22, the four playback devices 10a-10a
The synthesized sound of the audio signals Aa to Ad reproduced by d will be presented.

Overall control personal computer 30
Is the four playback devices 10a to 10d, the image synthesizing device 11, the switching device 12, and the high-definition character generation device 14 described above.
Has the function of controlling To this computer 30, a mouse 31 and a keyboard 32 are connected as input devices, and a hard disk 33 is connected as a storage device. The control output from the computer 30 is output as a control signal from the RS232C port, and the control signal is distributed to the four reproducing devices 10a to 10d and the image synthesizing device 11 via the RS232C multiplexer 34. To be done. Further, the computer 30 is provided with a function of giving a switching signal S to the switching device 12 and a cursor position designating signal C to the high-definition character generator 14 by an output of a system different from the RS232C port. .

Next, FIG. 2 shows an example of a screen displayed on the high-definition monitor 16 in this multimedia information presenting apparatus. In this example, the entire screen is the background screen 1.
And the window area screens 2 and 3 and the mouse cursor 4. FIG. 3 is a diagram showing only the background screen 1 extracted. This background screen 1 is a still image based on the high-definition image signal Va reproduced by the high-definition optical disc device 10a, and has buttons B0, B1,
The pattern of B2 is included. However, in FIG. 3, image data is missing inside the hatched window region. In other words, the inside of the window area is an image on the assumption that another image is inserted and synthesized. FIG. 2 shows a state in which such fitting synthesis is performed. Here, the screen 2 in the window area is a moving image based on the NTSC image signal Vb reproduced by the NTSC optical disk device 10b,
The window area screen 3 is displayed on the reproduction personal computer 10
It is a still image based on the image signal Vd reproduced by d. The definition of the window area and the image composition are performed by the image composition device 11.

Although the high-definition image and the NTSC image have different resolutions, the image synthesizing device 11 synthesizes them so that they have the same resolution as that of high-definition. However, since the NTSC image is originally a low-resolution image, even if the resolution is adjusted to the high-definition resolution, the resolution does not improve. The meaning of matching the resolutions here means matching the number of pixels for convenience.

The full-screen display as shown in FIG. 2 is a very effective display although the total amount of data required for the display is relatively small. That is, in this screen display,
Since the high-definition image is only used as a still image on the background screen 1, the amount of data can be very small compared to a moving image, even though it has a high resolution. On the other hand, the image on the screen 2 in the window area is a moving image, but the original data on the optical disk is NTSC instead of the high-definition image.
Since it is an image, the amount of data is also saved. Thus, the total amount of data required for the display of FIG. 2 is kept relatively low. However, the impression when looking at this display is that since the background screen 1 is a high-definition high-definition display, it is understood as a high-quality image as a whole, and a moving image is displayed on the screen 2 in the window area. Is displayed, it will be understood as an active image with movement as a whole.

Next, the operation of this apparatus will be described with reference to a concrete example. As described above, this device is controlled by the general control personal computer 30. In the hard disk 33 connected to the computer 30, information necessary for the overall control is stored in the form of a table. In this embodiment, a total of seven tables are prepared in the hard disk 33. These tables will be described below with a simple example.

The first table is a high-definition optical disk table (TA) as shown in FIG. This table is composed of an instruction code group for controlling the high-definition optical disk device 10a. In FIG. 4, the character string shown in one line corresponds to one instruction code. In each instruction code, the four-digit number following the first # is the instruction code number. The two-digit alphabetic character that follows the instruction code number and is separated by a colon is the "instructor", and the five-digit number (one set or two sets) that is further separated by the colon and is the "operand". . The instruction code number can be any combination of numbers, but in the example shown here, # 0000, # 0010, # 0020, # 003.
Every 10th number such as 0 and # 0040 is used. There are three types of "commanders" for the high-definition optical disk device 10a, "PL", "PA", and "LP". The commander “PL” means play and indicates an instruction to reproduce a moving image from the frame number position indicated by the operand. The commander "PA" means pause, and indicates an instruction to reproduce a still image corresponding to the frame number position indicated by the operand. The instruction "LP" means a loop, and of the two sets of frame numbers indicated by the operand,
It indicates an instruction to reproduce the moving image from the first frame number position and, when the moving image reaches the second frame number position, returns to the first frame number position and repeats the reproduction.

Specifically, if the instruction code number # 0000 is executed in the table shown in FIG.
When the moving image reproduction starts from the 994th frame and the instruction code number # 0010 is executed, the moving image reproduction starts from the 15342th frame. When the instruction code number # 0020 is executed, the still image of the 20512th frame is reproduced, and the instruction code number # 0030
Is executed, the still image of the 20513th frame is reproduced, and when the instruction code number # 0040 is executed,
The moving images up to the 16242nd to 17142nd frames are repeatedly reproduced.

The second table is NT as shown in FIG.
It is an SC optical disk table (TB). This table is composed of an instruction code group for controlling the NTSC optical disk device 10b. Each instruction code is exactly the same as in the above-mentioned first table. The third table is an NTSC optical disk table (TC) as shown in FIG. This table is composed of an instruction code group for controlling the NTSC optical disk device 10c. Again, each instruction code is exactly the same as the above-mentioned first table.

The fourth table is a reproducing computer table (TD) as shown in FIG. This table is composed of a group of instruction codes for controlling the reproduction personal computer 10d. Again, in FIG.
The character string shown in one line corresponds to one instruction code, and in each instruction code, the four-digit number following the first # is the instruction code number. The two-digit English character that follows the instruction code number and is separated by a colon is the "instructor", and the character string or number that is further separated by the colon and is the "operand". This reproducing personal computer 10
The "commanders" for d are "BP", "BT",
Five types of "SP", "ST", and "ON" are prepared. The commander "BP" means program play and indicates an instruction to play the program based on the file indicated by the operand. Here, the program is a multimedia-provided program created by the playback personal computer 10d, and based on the file specified by the "operand", a moving image, a still image, a character, a figure, a graph,
Various programs including display of such as and presentation of audio will be provided. The commander "BT" indicates a program stop and is a command to stop the program played by executing the "BP" command. That is, when the command code including the command "BP" is given from the general control personal computer 30, the reproducing personal computer 10d arbitrarily starts to play the designated program, and the command "BT". When the instruction code including "" is given, the program play will be stopped. On the other hand, the commander "SP" means sound play, and is a command to reproduce the audio CD built in the reproducing personal computer 10d. That is, the built-in audio CD is reproduced from the position indicated by the operand.
On the other hand, the command "ST" indicates that the sound is stopped, and is a command for stopping the reproduction of the audio CD reproduced by executing the "SP" command. Also, "O
The instruction code including the “N” instruction indicates an instruction to output a still image in the built-in hard disk, and the file specified by the “operand” is read from the hard disk and used as still image data. Will be output.

Specifically, in the table shown in FIG. 7, when the instruction code number # 3000 is executed, the file FILE1 is read from the hard disk,
Some program (for example, a program displaying a graph) will be played based on this file. This program play is stopped by executing the instruction code number # 3010. When the instruction code number # 3020 is executed, the reproduction of the built-in audio CD is started from the position of 3 minutes and 18 seconds, and when the instruction code number # 3030 is executed, the reproduction is stopped. Further, instruction code number # 304
When 0 is executed, a file FILE2 is read from the hard disk, and some still image is displayed based on this file.

The fifth table is an image composition table (TX) as shown in FIG. This table is composed of a group of instruction codes for controlling the image synthesizer 11. Again, in FIG. 8, the character string shown in one line is 1
Each instruction code corresponds to one instruction code, and in each instruction code, a four-digit number following the first # is an instruction code number. Two pairs of alphanumeric characters following this instruction code number separated by a colon are "instructors", and further separated by a colon and followed by x
Alternatively, the variable value with y is the "operand". This x
Alternatively, the variable value accompanied by y is actually a specific coordinate value corresponding to the display screen of the high-definition monitor 16.
That is, the variable value with x indicates the X coordinate value of the display screen, and the variable value with y indicates the Y coordinate value of the display screen. The “commander” for the image synthesizer 11 is “W
1: ON ”,“ W2: ON ”,“ W1: OFF ”,“ W
There are four types of "2: OFF". The image synthesizing process performed by the image synthesizing device 11 defines the high-definition image given to the input terminal I0 as the background screen 1, and defines the window area screen 2 or 3 in a predetermined part of the background screen 1, , An NTSC image given to the input terminal I1 or a reproduction computer image given to the input terminal I2 is embedded and combined. Commander "W1: O
“N” means that a screen portion in the window area 2
Where NTSC applied to the input terminal I1 is defined.
The command "W2: ON" indicates an instruction to perform a process of inserting and combining images. The command "W2: ON" defines the window area screen 3 in a predetermined part of the background screen 1 and is given to the input terminal I2. 9 shows an instruction to perform a process of fitting and synthesizing the reproduced computer image. In addition, the imperative "W1: O
“FF” is an instruction for canceling the screen 2 in the window area defined by the instruction “W1: ON”, and the instruction “W2: OF
“F” is an instruction to cancel the window area screen 3 defined by the instruction “W2: ON”. Commander "W1: O
“N” and “W2: ON” are accompanied by “operand”. This "operand" indicates the position and size of the screens 2 and 3 in the window area. That is, 2 in the first half
Two numerical values indicate the coordinate value of the upper left corner point of the window area to be defined, and the latter two numerical values indicate the coordinate value of the lower right corner point. After all, two points on the background screen 1 are specified by these coordinate values, and a rectangle having these two points as a diagonal is defined as a window area.

Specifically, in the table shown in FIG. 8, when the instruction code number # 4000 is executed, the upper left coordinate value (x11, y11) and the lower right coordinate value (x12, y1).
The rectangular area 2) is defined as the in-window area screen 2, and the image (either one of the image signals Vb or Vc) given to the input terminal I1 is fitted and synthesized in the in-window area screen 2. . Also, the instruction code number # 401
When 0 is executed, the upper left coordinate value (x21, y21),
The rectangular area having the lower right coordinate value (x22, y22) is defined as the window area in-screen 3, and the image (image signal Vd) given to the input terminal I2 is fitted into the window area in-screen 3 and synthesized. Become. Further, instruction code number # 4020
Is executed, the screen 3 in the window area is canceled and the image (image signal Vd) given to the input terminal I2 is not displayed. Further, when the instruction code number # 4030 is executed, a new rectangular area having the upper left coordinate value (x31, y31) and the lower right coordinate value (x32, y32) is defined as the window area inner screen 2, and within this window area The image (one of the image signals Vb and Vc) given to the input terminal I1 is fitted into the screen 2 and synthesized.

In the apparatus of this embodiment, as described above, up to two window area screens can be fitted,
It does not matter if more screens can be embedded. Further, when a plurality of screens are embedded, they may overlap each other, so it is preferable to include so-called layer information indicating which screen is to be displayed on top in the instruction code. For example, in FIG.
Somewhere in the table in the command "W1: ON"
The screen 2 in the window area defined by the command "W2:
Information indicating that it should be displayed as a layer (or, conversely, a lower layer) above the window area inner screen 3 defined by "ON" may be included.

The sixth table is a mouse table (TM) as shown in FIG. This table shows mouse 3
It is a table for recognizing the instruction by 1. The mouse 31 functions as a two-dimensional coordinate input device and also functions to input a trigger signal. That is, the integrated control personal computer 30 gives the cursor position designating signal C to the high-definition character generator 14 in correspondence with the position of the mouse 31. This allows
The high-definition character generator is a high-definition monitor 1
6 An image signal for displaying the mouse cursor 4 at a predetermined position on the screen is generated. When the operator clicks the button of the mouse 31, a predetermined trigger signal is given to the general control personal computer 30. The computer 30 recognizes the position of the mouse cursor 4 when this trigger signal is given (that is, when the mouse button is clicked), and with reference to the mouse table shown in FIG. Performs processing to jump to the instruction code shown in the mouse table.

In FIG. 9, again, the character string shown in one line corresponds to one instruction code. The next two digits indicate the number of mouse button settings.
Four coordinate values and a jump destination instruction code follow.
The four coordinate values indicate the coordinates of the upper left corner point and the coordinates of the lower right corner point of the closed area set as the mouse button.

Specifically, in the table shown in FIG. 9, when the instruction code number # 5000 is executed, a total of three mouse buttons are set. The first mouse button is a rectangular area having upper left coordinate values (x41, y41) and lower right coordinate values (x42, y42). In this embodiment, the closed area of the button B0 shown in FIG. 2 is the rectangular area. Correspond. Then, when the mouse cursor 4 is in the area of the button B0 when the trigger signal is given from the mouse 31, jump to AL9510 (instruction code number # 9510 in the general table to be described later). become. Similarly, the second mouse button
Upper left coordinate value (x51, y51), lower right coordinate value (x52,
y52), and in this embodiment, as shown in FIG.
The closed area of the button B1 shown in (1) corresponds to this rectangular area.
Then, when the mouse cursor 4 is in the area within this button B1 when the trigger signal is given from the mouse 31, jump to AL9520 (instruction code number # 9520 in the overall table described later). become. In addition, the third mouse button is the upper left coordinate value (x6
1, y61) and a lower right coordinate value (x62, y62) in a rectangular area. In this embodiment, the button B2 shown in FIG.
The closed area of corresponds to this rectangular area. And mouse 3
If the mouse cursor 4 is in the area within this button B2 when the trigger signal from 1 is given,
L9530 (instruction code number # in the overall table to be described later)
9530). Similarly, when the instruction code number # 5010 is executed, one mouse button is set in total, and when the instruction code number # 5020 is executed, two mouse buttons are set in total. Furthermore, when the instruction code number # 5030 is executed, the number of mouse buttons is set to 0, and the mouse buttons are not set.

The seventh table is an integrated table (AL) as shown in FIG. This table shows the execution order for each instruction code in each table described above. That is, in the instruction group listed in this integrated table (AL), the first two-digit alphabetic character is information for specifying the table, and the subsequent four-digit number is a numeral indicating the instruction code number in the table. is there. However,
Only one special instruction is included. The instruction starting with the character string "TI" is an instruction indicating the waiting time, and the following 4
The digit number is a number indicating the waiting time (unit is 0.1 second). However, this waiting time is the waiting time for the general control personal computer 30 to perform control based on the general table (AL), and is the four playback devices 10a.
The reproduction process by 10d and the jump process by the trigger signal from the mouse 31 are continuously executed even during this waiting time.

Now, what kind of display is made on the high-definition monitor 16 will be described with reference to the concrete example of FIG. First, the execution is started from the line of instruction code number # 9000. The first execution instruction is TA0000. This indicates that the instruction code # 0000 of the high-definition optical disc table (TA) shown in FIG. 4 is executed. This instruction code is "PL: 18
994 ”, which is a high-definition optical disc device 1
0a starts playing the moving image from frame number 18994. At this point in time, since no command for defining the screen in the window area has been executed yet to the image synthesizing device 11, the image synthesizing device 11 outputs the image signal Va given to the input terminal I0 as it is. Therefore, only the moving image reproduced by the high-definition optical disc device 10a is displayed on the screen of the high-definition monitor 16. The next execution instruction is the instruction TI0200. That is, it is an instruction to wait for 20 seconds,
As a result, the high-definition optical disc apparatus 10a reproduces the moving image from the frame number 18994 for 20 seconds. The next execution instruction is the instruction of AL9010, and the instruction code number # 9010 in this integrated table (AL) is continuously executed.

When execution of the line with the instruction code number # 9010 is started, the first execution instruction is TA0010. This indicates that the instruction code # 0010 of the high-definition optical disk table (TA) shown in FIG. 4 is executed. This instruction code is "PL: 1
5342 ”, which means that the high-definition optical disc apparatus 10a starts playing a moving image from frame number 15342. After all, at this point of time, no command for defining the screen in the window area has been executed to the image synthesizing device 11, so that the image synthesizing device 11 receives the input terminal I.
