Embodiment Construction

[0052] Examples see figure 1 As shown, this multimedia real-time interactive system is characterized in that the system includes: a control terminal for managing multicast members and controlling the flow direction and flow of data when the meeting is in progress, and a terminal connected to the control terminal;

[0053] The terminal is composed of two modules, the sending end and the receiving end of video and audio data streams;

[0054] The sending end module includes a collection module and a compression module of video and audio data streams, a QoS control module and a transmission protocol module. The video collection module is connected with the QoS control module through the video compression module, and the audio collection module is connected with the QoS control module through the audio compression module. The QoS control module is connected with the transmission protocol module, and the transmission protocol module is also connected with additional functional modu...

Abstract

The invention discloses a multimedia real-time interaction system and a multimedia real-time interaction system. The system comprises a control end and a terminal, wherein the control end is used for managing multicast members and controlling the flow direction and flow quantity of data in session; the terminal is connected with the control end and consists of a video and audio data stream sending end module and a video and audio data stream receiving end module; the sending end module comprises a video and audio data stream acquisition module, a video and audio data stream compression module, a video and audio data stream quality-of-service (QoS) control module and a video and audio data stream transmission protocol module; the receiving end module comprises a video and audio data stream transmission protocol module, a video and audio data stream QoS control module, a video and audio data stream decompression module, and a video and audio data stream playback modules; and the video and audio data stream transmission protocol modules of the sending end module and the receiving end module are interconnected by an internet protocol (IP) network. The system and the method can overcome the shortcoming that online students are in different areas and realize the real-time interaction teaching of online education, so that communication and exchange between schools and students are strengthened, teaching quality is improved, and beneficial exchange between students and teachers and between students can also be promoted.

Description

(1) Technical field [0001] The invention relates to a multimedia network communication system and a communication method using the system. (2) Background technology [0002] The real-time interactive system is a system that enables participants in different places to participate in discussions on the same topic through terminals and networks. Participants can not only hear the voice of the speaker, but also see the image and background of the speaker, and can also exchange data, text, charts and other information about the topic, so the participants can obtain more than teleconference With the development of VLSI and computer technology, the multimedia video conferencing system integrating computer interactivity, network distribution and multimedia information synchronization has broken through the traditional methods of computer, communication and television. The boundary of the system provides people with a new interactive service. [0003] The real-time interactive syst...
