Synchronous display method and device of images

Abstract

The invention provides a synchronous display method and device of images. Compression treatment is carried out through periodically capturing screen contents; the transmission capability can be realized at any time; the transmission effect is improved; and the transmission time can be shortened. The captured image contents can be quickly compared according to the feature values analyzed in the image compression process; the images are judged intelligently synchronously; the images are transmitted automatically synchronously without manual operation; the screen contents are prevented from being transmitted repeatedly; the storage pressure of a student user terminal is relieved; comprehensiveness of the contents is ensured; the screen image contents are marked and judged, the review efficiency of a student is improved, when the student reviews, the student can directly view the last few pages of blackboard-writings.

Description

technical field [0001] The present invention relates to a method for synchronous display of images, in particular to a method for synchronous display of images on the same screen, in particular to a computer-executed method for simultaneous display of images in the field of network teaching and the use of said method network teaching system. Background technique [0002] The teaching mode of the traditional teaching method is increasingly unsuitable for the needs of educational discovery. Due to the limitation of the venue and the non-repeatability of the classroom, there are usually the following defects: the order of the students' seats makes it difficult for the students behind to see the blackboard or projection clearly After class, students can only review the notes and cannot replay the class process. [0003] For the traditional teaching method, the basic method of the existing network teaching method in the prior art is: store the audio and / or video information of t...

[0002] The teaching mode of the traditional teaching method is increasingly unsuitable for the needs of educational discovery. Due to the limitation of the venue and the non-repeatability of the classroom, there are usually the following defects: the order of the students' seats makes it difficult for the students behind to see the blackboard or projection clearly After class, students can only review notes and cannot replay the process of class

As a result, teaching equipment needs to be installed in advance, and once installed, it is not easy to move

As a person involved in teaching and learning, you cannot take away the terminals you use. It is not convenient to use after the teaching process is completed, for example, it is not convenient for students to review

[0007] The existing network teaching system still has the following problems in the processing of synchronous display of the same image: the speed of receiving the same screen data by the student user terminal is slow, the teaching process is not smooth, and there is a phenomenon of stuttering

However, the acquisition of images in the prior art such as screen copy (or screen capture) is either manually performed, or automatically sent according to time settings, but there is a problem of whether the information sent by the screen capture is repeated and whether it is valid, unnecessary or Sending repeated images will increase the burden of network transmission and affect user experience
