Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device capable of displaying a screen and outputting sound, such as a computer and a video conference system.

[0002]

2. Description of the Related Art In recent years, the progress of image and sound processing technology using a computer has been remarkable, and an environment that can be widely used not only for workstations but also for personal computers to word processors is being constructed. Further, by using a window system, a device capable of simultaneously displaying a plurality of screens on the same display means (hereinafter referred to as a multi-window system) has been constructed, and a plurality of screens can be displayed at the same time, and the sound attached to those screens Is being widely used by the same speaker.

A conventional screen and a display device capable of outputting sound accompanying the screen will be described below. FIG. 3 is a block connection diagram of a conventional display device. As a component, 301 is a display unit for displaying a screen. A storage unit 302 stores screen data. 303 is a storage means 3
02 is a display data transfer means for transferring the display data from 02 to the display means 301. A storage unit 304 stores data such as screen data, acoustic data, and character data, and also stores control information and programs for implementing the multi-window system. A control unit 305 executes the program stored in the storage unit 304 and controls the display unit 301, the storage unit 302, the display data transfer unit 303, and the storage unit 304. Reference numeral 306 is a sound output means for outputting sound. Reference numerals 307 to 313 are buses connecting the respective stages.

The operation of the display device having the above-mentioned components will be described below. For the sake of simplicity, a case will be described in which, as shown in FIG. 4, two screens are generated and simultaneously displayed on the display means.

FIG. 4 shows a display example using a conventional device.
401 and 402 are display means, 403 and 404 are screens displayed on the display means 401, and 405 and 406 are screens displayed on the display means 402. The display means 40
Reference numerals 1 and 402 indicate the same display means, and FIG.
(B) shows a display state before the screen 403 is moved and a display state after the screen 403 is moved.

First, when the control means 305 executes a program for generating the screen 403, an area for storing display information of the screen 403 is secured in the storage means 304, and the screen position, size, background color, and the like are displayed. Information is stored by the control means 305 via the buses 311 to 313. The display data is stored in the storage unit 304 by the control unit 305.
The display data therein is transferred to the storage unit 302 via the display data transfer unit 303 and the bus 308. The display data transfer unit 303 reads the display data from the storage unit 302 and transfers it to the display unit 301 via the buses 307 and 308. As a result, the screen 403 is displayed on the display unit 301.
Displayed above. The above sequence is executed for generation and display of the screen 404. When the two screens are generated, they are displayed as shown in FIG. 4 (a), for example. The sounds accompanying the screens 403 and 404 are output by the control unit 305 by transferring to the sound output unit 306 via the sound data bus 310 in the storage unit 304.

Next, the screen 403 is moved, and as shown in FIG.
When the display state changes from FIG. 4B to FIG.
Reference numeral 05 indicates the updated position information of the screen 403 in the storage unit 30.
Rewrite to 4. Based on the updated location information,
The display data is updated from the control unit 305 and the storage unit 304 via the display data transfer unit 303 and the bus 308. The display data transfer unit 303 reads the display data from the storage unit 302 and transfers it to the display unit 301 via the buses 307 and 308. The sound associated with the display screen does not depend on the position of the screen and is stored in the storage unit 3.
The control means 305 transfers from 04 to the sound output means 306.

[0008]

However, in the above-mentioned conventional configuration, when a plurality of screens are displayed on the display means 301 and the sound associated with each of the screens is output from the same sound output means 306, There is a problem that it is difficult to determine which screen is associated with the sound. Also, when a plurality of screens are displayed with overlapping, the same problem occurs, and it is difficult to determine which screen the sound is associated with.

The present invention solves the above-mentioned conventional problems. It is possible to clearly distinguish the displayed screen and the accompanying sound, and even when a plurality of screens are displayed with overlapping, It is an object of the present invention to realize a display device that can clearly distinguish the accompanying sound.

[0010]

In order to achieve the above-mentioned object, the present invention displays a screen for displaying a screen, a storage for holding display screen data, and a screen for displaying the display screen data from the storage. Display data transfer means for transferring to the means, control means for controlling the display of the screen and the entire apparatus, storage means for storing programs and data to be executed by the control means, and sound output means for outputting sound. And a structure of a display device having a sound input function and provided with a sound processing unit for processing a sound accompanying a display screen based on position information of the display screen and inputting the sound into the sound output unit. To do.

Further, according to the present invention, a control means having a function of controlling the vertical relationship of at least two or more screens displayed in an overlapping manner, and an acoustic processing means having a function of processing an input sound from the information of the vertical relationship. And a display device provided with.

[0012]

With this configuration, the present invention firstly applies the position information of the display screen obtained from the control means to the sound processing means, and processes the sound based on the value so that the sound associated with other screens can be displayed. It is possible to easily distinguish between the two. Secondly, when a plurality of screens are displayed in an overlapping manner, the information on the upper and lower relations of the overlapping is input to the sound processing means, and the sound is processed based on the value, so that the sound can be distinguished from the sound of another overlapping screen. Is easily possible.

When the screen is generated, the control unit 218
Acoustic processor 2 for processing the sound accompanying the screen
In order to assign 02 and 203, the connection state of the router 201 is confirmed and the value of the register 206 is updated. By updating the register 206, the router 201 transfers the sound associated with the new screen to the sound processor 202 via the bus 212, and the sound associated with the already existing screen via the bus 213. Throw in. The control unit 218 calculates a parameter for acoustic processing from the display position information of the new screen, and the bus 216 is added to the register 204 connected to the assigned acoustic processing unit 202.
And write via 211. In order for the router 201 to distinguish which screen the audio data sent via the bus 217 belongs to, the audio data has header information corresponding to the audio processors 202 and 203 in a one-to-one correspondence. Has been added, and the router 201 recognizes this,
Sounds are distributed to the respective sound processors 202 and 203. The number of acoustic processors depends on the number of processed acoustics that are desired to be output at the same time.

When the overlapping screens are displayed, the overlapping information is put into the acoustic processor.
That is, two-dimensional coordinates that are information about the display position of the screen,
It is possible to easily analogize that it is possible to calculate the processing parameter from the three-dimensional information by sending the information on the upper and lower relations of the overlap, and it is possible to perform finer acoustic processing.
