After years of development, the recording and broadcasting technology has matured and the system architecture is similar. Basically, a recording and broadcasting host + automatic tracking host (using image tracking technology or infrared tracking technology) constitutes a recording and broadcasting system.
Since the self-survey visualization first proposed an integrated recording and playback host with embedded high-definition image tracking function, many manufacturers have followed suit and launched an “integrated†recording and broadcasting system. In fact, these recording and broadcasting systems are not really embedded tracking and integrated recording and broadcasting systems, but are skillfully combined into one, and the traditional tracking host and recording host are pieced together from the hardware architecture in a single chassis. In terms of shape, it is an integrated recording and broadcasting host, but there are two sets of independently running systems.
Then the title is coming. As a non-professional, how do we tell that the recording and broadcasting system is truly embedded and integrated, and is still a “pseudo†integrated recording of hardware?
Identify the first type, with or without additional analysis cameras. The integrated recording system with embedded tracking only has 4~5 HD cameras as the signal source for high-definition shooting, and the “pseudo†integrated recording and broadcasting system does not combine the hardware of the tracking host and the recording host. The two systems are truly "converged", so it still uses the original tracking architecture, which requires an additional 3 to 8 hemispherical surveillance cameras as analysis cameras in addition to several HD cameras as the source of the shots.
Identify the second type, whether the host has a lot of standard definition interfaces. The "pseudo" integrated recording and recording system using the analysis camera needs to connect these cameras and the image tracking system through the wire. The recording host must have an interface dedicated to connect the several analysis cameras, and both are standard definition. Interface, the entire recording and broadcasting system can only do standard definition analysis. The all-in-one recording system that really uses embedded tracking has only a few interfaces to the HD camera.
Identify the third type, whether it can debug the tracking parameters and host parameters in a unified interface. The real embedded tracking integrated recording and broadcasting system can debug the image tracking system and the host after entering the recording and debugging interface. The "pseudo" integrated recording and broadcasting system is not integrated because the tracking host system and the recording and broadcasting host system, so it is necessary to separately enter the two debugging interfaces of the tracking host and the recording and playing host to debug the entire recording and broadcasting system.
Different from the "pseudo" integrated recording and broadcasting of the above hardware assembly, the Yingying recording and broadcasting system adopts the method of embedding the image tracking software module into the recording and broadcasting host, sharing a unified set of hardware, which is a true embedded tracking integrated recording. Broadcast system. The recording and recording system of this architecture has no additional tracking host and analysis camera except for the four full HD shooting cameras and recording host. The four cameras capture the teacher's panorama, the teacher's close-up, the student's panorama, and the student's close-up, as well as the image analysis function. The principle is to use the teacher's panoramic camera to analyze the direction of the teacher, so as to send instructions to the teacher to track the camera to track the close-up, the same is true for student tracking.
The integrated recording system with software embedded in the host has the advantage of using 1080P full HD images to analyze the movements of teachers and students. Its accuracy is more than 5 times higher than that of image tracking using analysis cameras. The system is not chaotic. The patchwork "pseudo" integrated recording system cannot be compared.
