Analysis On The Development Trend Of Streaming Media Recording And Broadcasting Technology

With the rapid development of information network technology and multimedia technology. The convenience and practicability of the streaming media recording and broadcasting system has been recognized by the majority of users, and the Internet of Things and cloud computing technology are surging, which will inevitably bring about changes in the streaming media recording and broadcasting system.

At present, the streaming media recording and broadcasting system is evolving in two directions; the high-definition streaming media transmission of LAN or bandwidth line and the standard-definition streaming of the Internet and mobile communication networks, and the technological evolution will promote the performance improvement of the recording and broadcasting system, system performance. The promotion will also promote the expansion of the application space and field of the recording and broadcasting system.

The performance improvement of the recording and broadcasting system needs to be considered from the aspects of audio and video signal acquisition technology, camera tracking and positioning technology, automatic editing technology of teaching content, streaming media storage and publishing technology.

The enhancement of audio and video signal acquisition technology will further make the image effect clearer and smoother; the improvement of camera tracking and positioning technology will further enhance the automatic tracking ability; the automatic editing technology of teaching content will further improve the navigation and file publishing functions. The improvement of streaming media related technology is more convenient for application and communication.


More clear image effects

Most of the mainstream HD recording and broadcasting systems are now 720P30 frames. In order to make the images clearer and smoother, they will inevitably develop to 1080p 30 frames or 60 frames. In some areas, such as medical education, it is even necessary to be able to capture and transmit high-definition video signals with resolutions better than 1920*1080 in order to clearly record every detail of clinical surgery, which requires the use of a recording system to provide HD Video support.

One of the key technologies that need to be solved now is the unification of the high-definition video resolution dimension, which solves the problems of the transition from the standard definition video system to the high-definition video system and the huge difference between the private network and the Internet bandwidth resources, saving bandwidth and improving audio and video. quality.

Automatic tracking technology

The current automatic tracking technologies such as infrared positioning, ultrasonic positioning or image recognition technology are not perfect, and there is still a gap from true intelligence.

The steps of the teaching intelligent recording and broadcasting system using the classroom blackboard writing motion detecting method are as follows.

Image acquisition and calibration, using a video capture card to capture a frame of image; calibration of the blackboard area, inside the closed polygon is the blackboard area.

Motion detection, including motion detection through background modeling and updating, background difference, skin color difference, motion detection, and motion merging.
