Description

A method for co-editing a document, and an apparatus for implementing the same

The present invention relates to a method for co-editing a document, and an apparatus for implementing the same, and more particularly, to a method for co-editing a document for displaying a document that is changed according to the co-editing of a document by multiple users, and the same It relates to a device for implementation.

In the case of a system for co-editing a document by multiple users, multiple users access and edit the document at the same time. Therefore, the contents edited by multiple users should be reflected and displayed on the screen in real time, but a difference in rendering speed occurs depending on the size of the document and the performance of the device or browser used by each user.

Also, even when a user edits a document by adding only a few characters, the entire area of the document becomes a rendering target, which is inefficient.

In the case of the existing document co-editor, it is difficult to use a method that renders only the visible part of the document because it is often used to search for and edit the necessary content by the user, such as a word document, by pressing Control (Ctrl) + F. .

In addition, there is a method to solve the problem through a user interface, such as limiting the size of the document or providing a tab or a bookmark at the top, but this method also has a problem of causing inconvenience to the user.

Accordingly, there is a need for a method capable of preventing deterioration in rendering performance depending on the size of a document or access of multiple users when co-editing a document. In addition, there is a need for a method of rendering and showing only the revised part of the document when a revision occurs due to editing by multiple users.
