The multimedia recording and broadcasting system has video, audio, and data simultaneous live broadcast functions, and can simultaneously integrate video, audio, The data is broadcast live simultaneously, and the delay is controlled within 5 seconds. Each PC receiving terminal only needs to install simple playback software to watch simultaneously.
Synchronous recording: Simultaneously record video, audio, and computer dynamic screens, which can display the images, sounds, courseware, lecture notes, mouse operation tracks, and content written on the electronic whiteboard on the computer screen. The displayed content is simultaneously recorded to a file.
Real-time live broadcast; the video, audio, and computer dynamic screens of the classroom can be broadcast live on the Internet through unicast or multicast. Users can simultaneously receive the live video, audio, and video through the IE browser. Computer dynamic screen information.
Video and VGA signal collection uses broadcast-grade PCI-E high-definition VGA capture cards and recording and broadcasting encoders, as well as other front-end processing equipment for video and VGA signals (computer screens). It can be installed at the classroom site and provides major hardware interfaces such as audio, video and VGA. It receives signals output from microphones, cameras and computers respectively, and collects and efficiently encodes these signals to make them suitable for transmission on IP networks. The recording and broadcasting server receives audio, video and VGA data from the recording and broadcasting encoder, and stores, forwards and manages these data to realize live broadcast and on-demand functions.
These video files are too large to carry, transmit, and demonstrate, such as 3D animation files. Then you can use a VGA capture card or capture box with video editing software such as VideoStudio X2 and VideoStudio X2 to encode them. Use a VGA capture card or capture box to capture it into an uncompressed file AVI format for editing. The audio and video capture card is suitable for professional audio and video software development (such as Anychat), image analysis, and processing work. It can be widely used in microscopic imaging, medical imaging, intelligent transportation, analysis and measurement, biomedicine, machine vision, and industrial imaging. analysis, and a variety of other high-precision image processing and analysis fields.
High-definition and high-precision acquisition cards can be applied to industrial testing, industrial measurement, intelligent transportation, medical imaging, industrial monitoring, instrumentation, machine vision, webcasting, recording and broadcasting systems, VOD on-demand, distance education and training, Security surveillance, traffic tolls, image collection and other types of image collection, processing and analysis. The video conferencing system also provides free network and telephone technical support guidance and maintenance.
1. Screen monitoring
If you want to monitor the content displayed on a certain monitor, such as in the field of industrial automation, you can use a VGA high-definition capture card or capture box to capture the content displayed on this monitor. , transmitted to the monitor in real time, and can also be saved for subsequent viewing.
2. Screen live broadcast
A. Live broadcast the screen of the video conference, allowing more people who have no chance to participate in the video conference to watch;
B. Use VGA Using a capture card or capture box to do screen live broadcast, the picture is much clearer than other live broadcast methods.
C. In the teaching field, it can be used to live broadcast the teacher's computer screen to realize multimedia teaching or remote teaching;
3. Processing special video formats
Used VGA capture card or capture box cooperates with streaming media encoding software to capture and encode in real time into streaming media format, and put it on the streaming media server for everyone to watch on demand.
The file format of some video files is customized by the development company, and other companies' software cannot directly process them, such as teaching courseware, 3D animation files, etc. Some video files are too large to be carried, transmitted, and demonstrated, such as 3D animation files, then you can use a T200AE-VGA capture card or capture box with streaming media encoding software to encode them into a small streaming media format using a VGA capture card or a VGA capture card or box. The capture box captures it into an uncompressed file AVI format for editing.
4. Security X-ray machines, radar image signals, VDR recorders, medical X-ray machines, CT machines, gastrointestinal machines, etc.
