Embodiment Construction

[0049] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0050] figure 1 It is a resource data sharing method provided by an embodiment of the present invention, which is applicable to a first terminal, and the method includes the following steps.

[0051] S101. Synchronize local and at least one second terminal resource data.

[0052] The first terminal acts as an operation initiator, and the at least one second terminal acts as an operation receiver. The first terminal notifies the at least one second terminal through a preparation instruction to be ready to follow and process resource data synchronously. Through the preparation instruction, the first terminal synchronizes the displayed resource data between the local...

Abstract

The invention discloses a method for sharing resource data, including: synchronizing local resource data with at least one second terminal; recording resource data change information generated by user operations; sending operation instructions to the at least one second terminal, the The operation instruction includes the resource data change information. The present invention realizes the synchronous sharing of resource data change information between terminals, enhances the real-time performance and synchronization of resource data display between terminals, and occupies very little network resources. The invention also discloses a device for realizing the above method.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a data sharing method and device. Background technique [0002] With the continuous development of video technology and Internet technology, there are more and more occasions to apply multimedia interactive technology. In multimedia interactive conferences or teaching scenarios, the lecturer usually uses PPT slides as the main line to explain page by page. Each slide is sent as an image to the end devices used by students or participants. The handwriting and circle drawing performed by the lecturer on the slides require the terminal device used by the lecturer to share the handwriting synchronously with the terminal devices used by the students or participants. [0003] When sharing data, some use the teacher's end to send the data stream directly, and some set up a data stream server on the teacher's end and wait for each student's end to fetch the data stream. The a...
