Embodiment 1

[0021] Embodiment 1, here, one of the IP cameras is used as a teaching terminal camera and is located at the lecture terminal, and the rest are used as lecture terminal cameras and located at the lecture terminal. The lecturer gives lectures on the lecture terminal, and the audio and video are transmitted to the lecture terminal in real time through the teaching terminal camera and microphone. The lecture terminal is located in a multimedia classroom. The computers, projectors, speakers and microphones in the multimedia classroom are part of the lecture terminal. The computer is installed with the dispatching platform listening client program, and multiple microphones are evenly installed in the classroom; and 2-3 IP cameras are set up in the multimedia classroom as the terminal cameras for listening to lectures. In this way, this embodiment becomes a system suitable for long-distance teaching in large classrooms. Students watch the lecturer's explanation through a projector, ...

Embodiment 2

[0023] Embodiment 2, add teaching assistant terminal in embodiment 1, the joining of teaching assistant terminal confirms whether to allow by the speaker terminal, on the dispatching platform, the computer with camera and MIC (also can not have camera and MIC) ( Computers that have installed the teaching client program of the dispatching platform and are connected to the dedicated network) can be teaching assistant terminals, and the number of teaching assistant terminals is not limited, and the specific number is determined by the lecturer terminal. There can be other teachers at the teaching assistant terminal to attend classes, as young teachers training or learning observation or class observation; other teachers can also assist the lecturer to send some in-class materials to the class listening terminal, such as inserting video demonstrations in the classroom, etc. Assist the lecturer in teaching. In this way, this embodiment becomes a system suitable for distance teachin...

Embodiment 3

[0024] Embodiment 3, the computers in the computer room are used as the terminal machines for listening to lectures, and these computers are installed with the client program of listening to the lectures of the dispatching platform, and have cameras and MICs. There is one student at each lecture terminal. Students not only attend lectures, but also can ask questions at any time. These questions can be answered by the lecturer at the lecture terminal or by the assistant teacher at the teaching assistant terminal. The specific arrangements are made by the lecturer. The teacher decides. Such a system is very suitable for answering questions and exercises.

Abstract

The invention discloses a remote multimedia interactive teaching system based on SIP signaling, which relates to a remote multimedia interactive teaching system. The system comprises a server formed on an IP multimedia scheduling platform based on SIP signaling, a teaching terminal machine, a learning terminal machine, and an IP camera. The teaching terminal machine comprises a main teaching terminal machine and a teaching assistant terminal machine, wherein the main teaching terminal machine adopts a server provided with a scheduling platform main teaching control terminal program; the teaching assistant terminal machine adopts a computer provided with a scheduling platform teaching client-side program, a camera and an MIC which are connected with the computer; the learning terminal machine comprises a computer provided with a scheduling platform learning client-side program, projection equipment and microphone equipment which are connected with the computer; and the IP camera comprises a network camera and a network video server, and is classified into a teaching terminal camera and a learning terminal camera. The system can realize real-time remote interactive teaching and transmit more information and resources.

Description

technical field [0001] The invention relates to a remote multimedia interactive teaching system, in particular to a teaching system based on a SIP signaling network. Background technique [0002] The traditional distance teaching mode includes TV, audio and video products, video calls, network downloads, network Q&A, etc. Among these models, TV lacks interactivity and real-time performance, audio-visual products lack interactivity and real-time performance, video calls lack interactivity and real-time performance, network downloads lack interactivity and real-time performance, and online Q&A lacks multimedia performance. [0003] At present, if both interactivity and real-time performance are considered, and a large amount of multimedia data can be exchanged, the traditional NO.7 signaling or TV relay mode will occupy a huge amount of dedicated equipment and channel resources; To smooth real-time video and audio data. [0004] It can be seen that the bottleneck of distance...
