Problems solved by technology

When the teacher is explaining the courseware or exercises, there are often situations where the teacher just marks a key mark on the courseware or exercises and the picture changes little. If the traditional live broadcast technology is used, it will undoubtedly consume a lot of data traffic

Embodiment 1

[0074] This embodiment provides a live broadcast method, including:

[0075] S1. Obtain the first event generated by the anchor terminal.

[0076] Among them, the method for obtaining the first event generated by the anchor terminal can only intercept the events generated by the display software installed on the anchor terminal; the display software is used to play courseware, exercises and teacher's writing on the blackboard; and the teacher controls the video plug-in or audio plug-in User operations cannot be obtained. Therefore, another method needs to be used to obtain the operations performed by the preset plug-ins in the anchor terminal, and then the display software in the anchor terminal simulates and generates the third event corresponding to the operation. At this time, the first The third event is the user operation performed by the teacher on the video plug-in or audio plug-in, which can be obtained by the method used to obtain the first event generated by the anch...

Embodiment 2

[0093] This embodiment provides a live broadcast system, including:

[0094] The first obtaining module 1 obtains the first event generated by the anchor terminal;

[0095] Wherein, the third obtaining module 4 is used to obtain the operation performed by the preset plug-in in the anchor terminal; the second generation module 5 is used for the display software in the anchor terminal to generate a third event corresponding to the operation;

[0096] The second obtaining module 2 obtains the object corresponding to the first event, the event type and the event parameter, and obtains event information;

[0097] When the event parameters include the first coordinate information, the conversion module 6 converts the first coordinate information according to the resolution of the host end and the resolution of the viewer end to obtain the second coordinate information; the second coordinate information covers the event information First coordinate information;

[0098] The first g...

Abstract

The present invention relates to the field of live broadcast, in particular to a method and system for live broadcast. The present invention acquires the first event generated by the anchor terminal; acquires the object, event type and event parameter corresponding to the first event to obtain event information; and the audience terminal generates the second event corresponding to the event information. The present invention is used for synchronizing the event information of the host terminal and the viewer terminal, and the capacity occupied by the event information is greatly reduced, which greatly reduces the data flow required during the live video broadcast process, and further reduces the requirements for network bandwidth and equipment during the live broadcast process .

Description

technical field [0001] The present invention relates to the field of live broadcast, in particular to a method and system for live broadcast. Background technique [0002] The traditional live video technology is to collect the video signal of the anchor in real time, encode the collected video signal into streaming data and send it to the audience through the network. Due to the large capacity of the video signal, the traditional live video technology is difficult The requirements for network bandwidth and live broadcast equipment are relatively high. [0003] At present, online education has entered thousands of households. The live video broadcast of online education usually transmits pictures such as courseware, exercises and blackboard writing to the audience, while the anchor side usually uses some kind of software to display courseware, exercises and blackboard writing. When the teacher is explaining the courseware or exercises, there are often cases where the teach...
