[Audio Network Information] Recently, well-known American universities such as Yale, Harvard and MIT have started classes online, and released video videos for users to download. At one time, many white-collar workers are eager to “teach†on the Internet. Here, download the potato Youku upload, QQ and everyone share the link to fly everywhere, not only can be a famous school, but also easy to "charge", why not?
Faced with the enrollment and publicity campaigns of well-known foreign universities in Hong Kong and Hong Kong, domestic universities are not willing to lag behind, and they hope to digitize and network the original quality courses, realize the transformation of classroom resources to open online resources, and establish high-quality classroom teaching videos. Resource library. But all this is done, only the hardware makes the colleges and universities have a headache. According to the traditional high-quality course recording method, it will cost a lot of manpower and material resources. The teaching video of one class will use several audio-visual personnel from recording to finished products. Day time.
The development of the recording and broadcasting system is undoubtedly the gospel of the open network course of domestic famous universities, which will provide strong support for the digitalization and networking of high-quality classroom resources. For example, the high-definition recording and broadcasting system of AVA under the “recording, dissemination, and high-quality audio and video†industry can provide a solution for domestic colleges and universities to open network courses.
So what is a recording system? To put it simply, the recording and broadcasting system can integrate the video signals of video, audio and electronic equipment recorded on the scene (including computers, video booths, etc.) into a synchronous recording, and generate standardized streaming media files for external broadcast, storage and later. Edit, on-demand.
The AVA HD Recording System is a powerful classroom recording and live broadcast device with 2-3 HD cameras with recording, live, on-demand, guided (switching), storage and tracking functions, all integrated Easy to use in one device.
There are four advantages to using the AVA HD Recording System to build a network open class.
The device is easy to install and easy to operate, and the recording course can be completed by one person
The high integration of AVA HD recording equipment eliminates the need for redundant external wiring and signal debugging. The use of the equipment is extremely simple, and only one operator can do all the work.
Remote navigation platform
The unique remote navigation platform and mouse click tracking technology, the operator does not need to visit the classroom, log on to the background of the recording system through the network, and complete the recording of the course on the remote navigation platform. The monitoring interface of the remote navigation platform can view the images of the teacher screen, the student screen, the blackboard screen and the computer screen or the electronic whiteboard screen in real time. If the automatic recording mode is enabled, even the teacher who attends the class can complete the recording of the teaching course.
The recorded course video is of high quality, the picture is clear and stable, and the nature is switched.
Mouse click tracking
AVA's HD recording system is equipped with a high-definition camera that can record 1080P HD video and uses hardware codec to ensure that the classroom and student performance in the course video are clearly presented.
The system's built-in remote navigation platform and mouse click tracking technology enable managers to switch images between multiple images with a single mouse click. The image is switched smoothly, without “jumping†and enabling multiple picture-in-picture functions. The system's preset switching function allows you to pre-customize scenes such as panorama, mid-range, and close-up, and quickly switch scenes with a mouse click. The recorded course video switches naturally and the lens zoom is stable.
Multi-channel video and audio signal input integration, recorded course video content enriched by a number of high-definition cameras, teachers and students' signals, microphone pickup sounds, electronic whiteboard signals and teaching courseware signals will be input simultaneously for the operator Integration is done through the pilot platform. The recorded course videos have a wealth of information, including not only the teacher's explanations and the interaction between teachers and students, but also the ability to cut into the clear electronic whiteboard screen or the teacher's projected courseware screen.
Fully automatic generation of standard format video, recorded course video is easy to save and spread AVA's high-definition recording system can automatically generate standard format video, automatically generate international standard streaming media file format wmv and asf after recording, not only save Going to the post-processing time, and the video in wmv and asf format is easy to save and spread on the Internet. The video of the course can be played perfectly using the player that comes with the computer. It can be uploaded to the school website for on-demand and download without conversion format.
