1, HD camera:
At present, the HD standards are 720p, 1080i, 1080p. To meet the requirements of HD video, its vertical resolution must exceed 720 (for example, 1280×720, 1920× 1080, etc.). In addition, the high-definition standard requires the length and width of the TV screen. The camera used in a real high-definition recording and broadcasting system must output high-definition video, usually using digital methods such as YPbPr or HDMI.
2, automatic tracking:
The latest target tracking is lock tracking based on moving image intelligent algorithm. Compared with the early infrared locking tracking, it does not need to wear any auxiliary equipment and is not disturbed by light. The locking and tracking of moving image intelligent algorithm includes three parts: target capture camera, video analysis and pan-tilt control module, and target tracking camera. At present, the products of Hangzhou Puxin can integrate these three parts, which greatly simplifies the erection of recording and broadcasting system.
3. Intelligent recording and broadcasting:
The so-called intelligent recording and broadcasting is a fool-like operation. Without complicated operation steps and professionals, teachers can start recording with one button and stop recording with one button. The system can automatically perceive students' speeches, teachers' actions such as operating computers and writing on the blackboard, and automatically switch the recording main picture. Automatically forms the beginning and end of the video, just like movie program.
4. Other functions:
An advanced recording and broadcasting system also needs to include a pilot system that allows manual control, which can control the recording process, manual screen switching, camera orientation, expansion and contraction, etc. Including various video signal material recording, file playback, format conversion, cutting, automatic uploading, recording, on-demand live broadcast platform and many other functions. The PX600HD intelligent recording and broadcasting system of Hangzhou Puxin Information Technology Co., Ltd. is a high-end recording and broadcasting system, which contains all the above functions.
