2. Description of the Related Art In recent years, it has been actively used to display several small screen windows on a display screen of a computer or a television. As the first conventional technique for controlling this window, there is a method for controlling a multifunctional dual screen of a wide clear vision television (Matsushita Electric Industrial Co., Ltd.).
Instruction manual P22) made by "TH-32WS40".

This window control method uses a tile type window in which the windows obtained by dividing the television screen into two parts are not overlapped, and different television broadcasts can be viewed in the left and right windows. . Therefore, to change the TV screen from one screen to two screens, the attached remote controller (hereinafter "remote control")
It is necessary to press the "2 screen" setting button.

As a second conventional technique, X-Window is used.
There is a system (a trademark of Massachusetts Institute of Technology).
In this system, the windows displayed on the display screen may overlap. However, in order to create and delete windows, the user has to perform operations for creating and deleting windows. As a third conventional technique, there is a "multi-window display device" described in Japanese Patent Laid-Open No. 5-80966. This technology can display multiple moving images or still images in a multi-window.

As a fourth conventional technique, Japanese Patent Laid-Open No. 5-11
There is a "multi-window moving image display method and apparatus" described in Japanese Patent No. 3864. With this technology, it is possible to output only the sound for a specified moving picture from a plurality of moving picture display windows and selectively listen to the necessary sound.

By the way, the conventional first
In the above technology, when different TV broadcasts displayed in the left and right two windows become the same TV broadcast by the channel operation, the same program is broadcast in two small windows. In order to avoid this, it is troublesome for the viewer to give an instruction to switch to the one-screen display by operating the remote controller.

In the second conventional technique, a large number of windows can be opened on the display screen by a generation command, which is convenient, but a large number of windows cannot be opened once they are closed by a delete command. Since unnecessary windows exist, it takes time to search for a required window, resulting in a decrease in work efficiency.

Further, in the third conventional technique, a moving image or a still image designated on the display screen can be displayed like a window, but windows cannot be integrated depending on the contents of the displayed moving image. In addition, the conventional fourth
With this technology, it is possible to select a window and output and play the corresponding audio. However, when a window is newly created or deleted, the corresponding audio is output unless the window is selected again. I can't.

Further, in the second to fourth conventional techniques, the size of the window can be freely set, but the window form cannot be changed according to the display content of the window. In view of the above problems, it is a first object of the present invention to provide a window control device capable of changing a screen to an easy-to-see screen without performing a complicated operation when contents displayed in a window are the same. And

A second object of the present invention is to provide a window control device capable of changing the form of a window in accordance with the contents displayed in the window so that the contents can be understood at a glance at the window. A third object of the present invention is to provide a window control device that makes it easy for a plurality of persons to use a window displayed on a display screen even when there are a plurality of persons who give a window generation instruction. is there.

A fourth object of the present invention is to provide a window control device capable of easily changing the output of sound in accordance with the generation and deletion of the window displayed on the display screen.

[0012]

In order to solve this problem, the present invention is a window control device of a system for displaying information by opening at least one window on a display screen, and a window identifier for identifying the window. Window information storage means for storing an information table including at least one or more pieces of window information in which the layout of the window itself on the display screen, shape information, window, and attribute values that are displayed information are associated with each other. A change instruction receiving means for receiving a change instruction of the window information stored in the window information storage means, and determining whether the attribute value related to the change instruction satisfies a predetermined condition with the attribute value in the window information The window determination control means closes or opens the window on the display screen.

As a result, the window determination control means is
Since the window whose attribute value in the window information satisfies the predetermined condition is displayed on the display screen, it is possible to switch to a screen that is easy to see without complicated operations.

The command input unit 1701 includes, for example, a keyboard, a mouse, and the like, and receives an input of a command for generating and displaying a new window of a user or a display command for displaying a document. The received command is sent to the control unit 17 via the command receiving unit 1702.
06 is notified. The display command for displaying the document includes a display command, a document identifier for specifying the document to be displayed, and a window identifier for identifying the window for displaying the document.

The command receiving section 1702 has a command input section 170.
The control unit 1706 is notified of the command accepted by the controller 1. The window management unit 1704 stores an information table 1801 as shown in FIG. This information table 180
1 includes window information 1807, 1808, 1809.
As a window identifier 180 for identifying a window
2, a display document identifier 1803 for identifying a document to be displayed in the window, a window size 1804 indicating the size of the window, a window position 1805 indicating the display position of the window, and a record order 1806 indicating the order in which the window information is recorded. The attribute value of each attribute is recorded.

Although the window is opened on the display screen of the display unit 108 by the window generation / display command, the attribute value of the display document identifier 1803 of the window information 1807 which has not been notified of the document display command is empty. It remains. The attribute value “1” of the record order 1806 means that it is displayed on the foreground of the display screen of the display unit 108. Therefore, when the windows are displayed in the overlap format, the windows may overlap depending on the window size 1801 and the window position 1805, but the record order 1
The smaller the attribute value of 806, the less hidden it is by other windows.

The display control unit 1703 opens or closes a window according to an instruction from the control unit 1706, and displays a document in the opened window. Upon receiving a notification from the control unit 1706 that the window information has been updated and a display instruction, the window information is read from the window management unit 1704, and the window identified by the window identifier 1802 is set ahead of the record order 1806 (value having a small attribute value). )

When the command notified from the command receiving unit 1702 is a command to generate and display a new window, the control unit 1707 writes new window information in the information table stored in the window management unit 1704. On this occasion,
A window identifier is added as window information, and the window size, window position, and record order attribute values included in the command are written. When the window information is updated, the display control unit 1703 is notified with the display instruction that the window information has been updated.

When the command notified from the command receiving unit 1702 is a display command for displaying a document, the window information of the window different from the window identifier included in the display command of the window information stored in the window management unit 1704. An attribute value in which the attribute value of the display document identifier 1803 and the document identifier included in the display command are matched is searched. When it finds a matching attribute value,
The attribute value of the record order 1806 of the window information having the document identifier as the attribute value is rewritten to "1", and the attribute value of the record order of the other window information is smaller than the attribute value before rewriting by "1". Lower. At the same time, the window information of the window identified by the window identifier included in the display command is deleted.

As a result, it is possible to display the window in a position that is easy to see without displaying an unnecessary window that displays the same document, and it is possible to effectively use the limited display screen space. . For example, when the information table 1801 illustrated in FIG. 18 is stored in the window management unit 1704, the information illustrated in FIG. 19 is displayed on the window 1 of the display screen of the display unit 108.
It is displayed in 807, 1808, and 1809.

When the control unit 1706 is notified of the window identifier “3” and the command “show document2”, the control unit 1706 causes the document identifier “doc”.
“Document2” is the display document identifier 1 of the window information 1808 identified by “2” of the window identifier 1802.
It is found to be the same as “document 2” in 803. The record order of the window information 1808 is rewritten to "1" and the record order of the window information 1809 is rewritten to "2". Further, the window information 1807 identified by the window identifier “3” is deleted. As a result, the display screen of the display unit 108 is changed to display windows 1808 and 1809 as shown in FIG.
