Problems solved by technology

[0003] However, in the above-mentioned information interaction system, the communication between terminals is limited to files, that is, the information sent by one terminal to other terminals can only be a complete file, which restricts the user to complete only one file before sending it to another terminal. Other end users reduce the real-time nature of information interaction, especially for information in the form of graphics, there is a problem of transmission

Embodiment Construction

[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited thereto.

[0035] figure 1 The flow chart of graphics transmission provided by the embodiment of the present invention. Such as figure 1 As shown, the graphic transmission process is suitable for information interaction systems, including the following steps:

[0036] Step 101, the terminal is connected to the central control device of the information interaction system.

[0037] Set the authority for the terminal as needed, for example, set the administrator authority for the terminal held by the teacher, as the sending terminal, and the terminal held by the student as the receiving terminal.

[0038] By default, the sending terminal of the administrator can send and display its own drawing graphics on other receiving terminals in real time. Other receiving terminals can rece...

Abstract

The invention provides a method and system for transmitting graphs. The method and system are suitable for an information interaction system. The method comprises the steps that a terminal is connected to the central control device of the information interaction system; a sending terminal sends initialization instructions to a receiving terminal, and the receiving terminal completes initialization; the graphs are drawn by the sending terminal; the sending terminal records the pixel points of the tracks of the graphs, and the pixel points are sent to the sending terminal through the central control device by adopting the instructions; the receiving terminal displays the graphs according to the instructions. According to the technical scheme, due to the fact that the information of the pixel points of the graphs on a user terminal are recorded and sent to other terminals in real time, the real-time transmission of the graphs is achieved, the range of information interaction is widened, and the efficiency of the information interaction is improved.

Description

technical field [0001] The invention relates to the technical field of information interaction, in particular to a method and system for graphic transmission. Background technique [0002] At present, in an information interaction system, information exchange can be realized between terminals through a central control device. For example, in a classroom environment built with an information interaction system, the teacher can upload the teaching materials or test papers to the central control device through the terminal held by the teacher, and then send them to the terminal held by the students. The test papers are uploaded to the central control device, and then sent to the terminal held by the teacher. In this way, the two parties can quickly complete file transfer and realize information exchange. [0003] However, in the above-mentioned information interaction system, the communication between the terminals is limited to files, that is, the information sent by one ter...
