Problems solved by technology

[0004] However, since the distance teaching system is often established between most students and teachers, limited by the transmission quality and size of teaching resources, there are often problems such as intermittent images, out-of-sync audio and images, and large delays.
And the system itself has strict authority management

Embodiment Construction

[0020] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0021] A teaching terminal based on Internet instant messaging technology, which comprises: an image display module 1, a video codec 2, an audio codec 3, a communication protocol stack 4, and a file storage manager 5, wherein the audio and video codecs are both The open source library of x264 is used, compiled and packaged into a JNI for JAVA to call locally, and then add the corresponding configuration to use.

[0022] The above-mentioned image display module 1 includes: a view component, a view container component, a layout component and a layout parameter module.

[0023] The above-mentioned video codec 2 adopts double buffering and multi-thread processing technology, so that image acquisition, compression and transmission can be performed concurrently, thereby improving the overall performance of the codec.

[0024] The communication protocol stack 4 mentione...

Abstract

A teaching terminal based on an internet instant communication technology is composed of an image acquisition module 1, a video encoder / decoder 2, an audio encoder / decoder 3, a communication protocol stack 4 and a file storage manager 5, wherein the video encoder / decoder and the audio encoder / decoder both adopt the X264 open source bases to encode, then are packaged into a data source for local calling, and then can be used by adding the corresponding configuration. The teaching terminal which realizes the interactive teaching via the internet instant communication technology satisfies the teaching demands and realizes the instant interaction and communication of the teachers and the students. Moreover, a system can realize the link sharing of the intelligent mobile terminals, such as the mobile phones, the tablet personal computers, etc., based on a mobile internet communication technology, thereby reducing the limits of a conventional remote teaching system. The teaching terminal is simple in structure, reasonable in design and stable in system, provides an instant communication channel for a remote teaching and learning companion system, saves the time, and is convenient for the instant interaction between the teachers and the students.

Description

technical field [0001] The invention relates to an instant messaging terminal, in particular to a teaching terminal based on Internet instant messaging technology. Background technique [0002] At present, a wide range of remote multimedia interactive teaching systems are used, which can form teaching resources by compressing video and audio on the teaching site and synchronously browsing courseware, etc., and use the network to transmit them to remote students' computers in real time, so that students can share teaching in a timely manner. Resources, through text communication and other means to achieve distance interactive teaching. [0003] The remote multimedia teaching system is suitable for a variety of network environments, and can also be used in remote real-time interactive teaching and training in enterprises, institutions, and the military; it can realize real-time interaction between the teacher's end and the remote classroom. In terms of video, teachers You can...
