Abstract
The utility model relates to an interactive host computer of web -based instruction, including audio acquisition module, video acquisition module, audio and video processing module, interactive teaching transmission and receiving module, interactive teaching video output module, the sound transmission of video information that audio acquisition module and video acquisition module will be gathered compresses for audio and video processing module encode, audio and video processing module transmits the sound video information who handles well to network through the interactive teaching transmission with receiving module to receive the sound video information of other interactive host computers from the network through interactive teaching transmission and receiving module, and with received sound video information transmit for behind the audio and video processing module code again the transmission give interactive teaching video output module output image and sound on local display device. Synchronous transmission is carried out with mr, student and whiteboard picture to the more than enough picture intelligence switching of this interactive host computer ability or many pictures simultaneous transmission's novel mode, is applicable to remote network interactive teaching more.
Description
Technical field
This utility model relates to electronic device field, particularly relates to a kind of Web-based instruction interaction main frame.
Background technology
Existing interactive main frame is mostly used in Remote Video Conference etc., point-to-point or point-to-points pattern transmission audio frequency and video, can carry out audio-video-interactive by network, namely see the other side's picture, hear the other side's sound between multiple interaction points.Also part interaction main frame was had to be applied in other field in recent years, such as education, court's trial etc..
The shortcoming that existing interactive main frame exists: be not associated with long-distance education practical situation, a transmission of one line teacher or student's picture, it is impossible to the integral status of the actual teachers and students attended class and electronic whiteboard picture is transmitted.The audio frequency and video that far-end is seen are long with the actual time delay time, and after speaking in a classroom, another classroom just can be heard after spending at least 3 seconds, has a strong impact on interactive teaching process.The compress technique of HD video falls behind, and bandwidth requirement is big.
Summary of the invention
For the defect that prior art exists, the utility model proposes a kind of Web-based instruction interaction main frame, the audio frequency and video being capable of network transmission reach low-down effect with actual time delay, and the new ant algorithms that energy more than enough picture intelligence switching or many pictures transmit simultaneously, teacher, student and electronic whiteboard picture are carried out synchronous transfer, is more applicable for telecommunication network interactive teaching.
For realizing above-mentioned functions, the utility model proposes a kind of Web-based instruction interaction main frame, including audio collection module, video acquisition module, audio frequency and video processing module, interactive teaching transmission and receiver module, interactive teaching Video Output Modules；The audio/video information collected is transferred to audio frequency and video processing module and is encoded compression by described audio collection module and video acquisition module；The audio/video information handled well is transferred to network by interactive teaching transmission with receiver module by described audio frequency and video processing module, and received the audio/video information of other interactive main frames by interactive teaching transmission and receiver module from network, and be transmitted further to interactive teaching Video Output Modules after the audio/video information received is transferred to audio frequency and video processing module coding on locally displayed equipment, export picture and sound.
Described audio collection module comprises audio input interface；Described video acquisition module comprises 2 high definition SDI input interfaces and 1 VGA input interface；Described interactive teaching Video Output Modules comprises 1 VGA output interface and 1 audio output interface；The transmission of described interactive teaching comprises 1 network interface with receiver module.
Beneficial effect
Compared with prior art, this utility model is capable of transmission multichannel picture, and classroom overall condition is fully reflected by teacher, student and electronic whiteboard；Audio frequency and video are short with the actual time delay time, and under the premise that network is smooth, time delay was less than 1 second.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As it can be seen, the utility model proposes a kind of Web-based instruction interaction main frame, including audio collection module, video acquisition module, audio frequency and video processing module, interactive teaching transmission and receiver module, interactive teaching Video Output Modules；The audio/video information collected is transferred to audio frequency and video processing module and is encoded compression by described audio collection module and video acquisition module；The audio/video information handled well is transferred to network by interactive teaching transmission with receiver module by described audio frequency and video processing module, and received the audio/video information of other interactive main frames by interactive teaching transmission and receiver module from network, and be transmitted further to interactive teaching Video Output Modules after the audio/video information received is transferred to audio frequency and video processing module coding on locally displayed equipment, export picture and sound.
Described audio collection module comprises audio input interface；Described video acquisition module comprises 2 high definition SDI input interfaces and 1 VGA input interface；Described interactive teaching Video Output Modules comprises 1 VGA output interface and 1 audio output interface；The transmission of described interactive teaching comprises 1 network interface with receiver module.
: high definition SDI video input 1, it is used for gathering teacher's image, 6.: high definition SDI video input 2, is used for gathering student's image, 7.: VGA input interface, be used for gathering teachers' instruction computer picture in accompanying drawing 2 5..
This utility model is in conjunction with remote interactive teaching practical situation, it is possible to transmission teacher, student and electronic whiteboard multichannel picture and whole classroom sound, and classroom overall condition is transmitted through the network to other interaction points.The shortcoming that before solving, interactive main frame single channel video can not reflect classroom overall condition.The audio frequency and video that this utility model is capable of through network transmission are comparatively short with the actual time delay time so that interactive teaching can smooth and easy carry out, the problem that before solving, interactive main frame output audio frequency and video time delay is long.This interaction main frame transmission bandwidth demand is low, advanced video compression technology, under the premise ensureing HD video quality, has high compression ratio so that interactive teaching also can smoothness carry out under the environment of low bandwidth.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
