Recording And Broadcasting System Has Become The Foundation Of Digital Campus

Recording and broadcasting system has become the foundation of digital campus   

Recording and broadcasting classrooms is to build a recording and broadcasting system, decorate the environment required for recording and broadcasting video, including classrooms for lighting, sound absorption, and other multimedia equipment. Recording and broadcasting classrooms can be mixed with multimedia classrooms and computer classrooms for school teachers to record teaching videos.

The recording and broadcasting system can record and synchronously record the video, audio, and electronic device image signals (including computers and video booths) recorded in the field to generate standardized streaming media files for external broadcast, storage, post-editing and on-demand broadcasting.

According to the resolution of the recorded video, the recording system is divided into standard definition, high definition, and full HD recording and broadcasting systems; according to the system structure, it is divided into integrated, distributed, and integrated recording and broadcasting systems. The recording and broadcasting system has three recording methods: fully automatic, semi-automatic, and full manual (that is, remote guidance), which can use automatic tracking technology to record video under unmanned control, and can also record high-quality teaching video resources through manual remote guidance. Remote guides are available in both C/S and B/S formats. In this part of the track, it has experienced ultrasonic and infrared web tracking, and it has now developed a technique for image location tracking.

In traditional classroom video recording methods, cameras need to be set up on the spot. Each camera needs one person to control, and a staff member needs to switch with the guidance switcher or through post-editing. Every time you record a video, it takes a lot of manpower and material resources. However, after using the recording and broadcasting system, the teacher's operation was greatly liberated. In this way, primary and secondary school teachers can record a large number of videos, analyze their own videos, improve their own teacher skills to promote the professional development of teachers, and use more video technologies to achieve demand for refined video-on-demand and student personality. Supporting learning; through network technology, the goal of co-constructing and sharing video resources.
