The well-known teachers in various disciplines owned by Huanggang Middle School are extremely valuable assets. In order to make high-quality teaching resources play a greater role, the school specially cooperates with a well-known domestic brand to completely record the classroom teaching content of its famous teachers, and then built in the In the brand video learning machine, more students eager to receive quality education can get the guidance of the famous teachers of Huanggang Middle School without leaving home, appreciate the style of the famous teachers, listen to the teachings of the famous teachers, and improve the radiation effect of high-quality teaching resources.
Video learning machine
At the beginning of the cooperation, Huanggang Middle School set up a digital studio, sent special staff to carry the camera to each classroom for recording, after recording, they were aggregated to the studio, collected, edited and output to the video learning machine, Although the work flow is clear, there are still many problems in the operation: the impact and impact of staff entering the classroom on classroom teaching, the overall arrangement when several classrooms are recorded at the same time, the single-camera recording cannot perfectly reproduce the charm of famous teachers ’classroom teaching, The coordination of multi-camera recording is difficult, and the collection and editing workload after multi-camera recording is large, and so on.
If there are not many classroom videos recorded, these difficulties can still be overcome, but if thousands of classrooms need to be recorded, collected, and edited, this will be a bottleneck that restricts the construction of a high-quality teaching resource library. However, according to the news released by the well-known brand, currently its video learning machine has built-in cooperation with Huanggang Middle School to record 10,000 classroom videos, how can this be done?
It turned out that Huanggang Middle School joined hands with the industry-leading Aoweiya Technology (hereinafter referred to as AVA) to adopt a distributed recording system independently developed by AVA. The system uses a remote guide to record, and no longer needs the photographer to carry the camera to "penalize" in the classroom. The original remote guide platform of the AVA recording and broadcasting system perfectly solves the problem of large-scale classroom video recording, and provides an excellent solution for the construction of Huanggang Middle School's high-quality teaching resource library.
REN-II distributed recording and broadcasting system
The AVA distributed recording and broadcasting system is a powerful classroom recording and live broadcasting device, with multiple functions such as recording, live broadcasting, on-demand, directing (switching), storage, etc., and all integrated in one device, simple and easy to use. The recording and broadcasting system adopts a distributed structure, which can record and live broadcast 16 "programs" at the same time. Each "program" supports simultaneous recording and live broadcast of 2 HD 720P videos and 1 HD VGA signal, as well as online on-demand later. .
If the distributed high-definition recording and broadcasting system supports the simultaneous recording and live broadcasting of 16 "programs", which can greatly reduce the workload of the staff, improve work efficiency, and significantly reduce costs, then its built-in remote guidance platform can Significantly improve the quality of the recorded video and reduce the difficulty of post-editing and processing.
AVA's remote guidance platform allows administrators to use the IE browser at a remote location to log in to the recording and broadcasting system, and control, track, push, pull, and turn the camera through the mouse, and easily switch between different camera screens. For skilled operators, even multiple classrooms (programs) can be remotely controlled at the same time, and standard streaming media files can be directly generated for on-demand or post-editing after recording.
These two advanced technologies can completely avoid interference with teaching activities, and greatly reduce the workload of the staff: the work that was originally completed by 3-5 people can now be completed by only one person; the original 1 -A series of work that can be completed in 2 days, now only needs one lesson to realize the recording and generating work.
