After years of advancement, recording and broadcasting technology has become more mature, with similar system architectures. Typically, a recording and broadcasting host combined with an automatic tracking host—using either image or infrared tracking technology—forms the core of such a system.
When self-survey visualization first introduced an integrated recording and playback host with embedded high-definition image tracking, many manufacturers followed suit, launching their own "integrated" systems. However, these systems are not truly embedded or fully integrated. Instead, they are just hardware combinations, where traditional tracking hosts and recording hosts are merged into a single chassis. In appearance, it looks like a single unit, but in reality, there are two separate systems running independently.
So, how can a non-professional distinguish between a real embedded and integrated system and a "pseudo" one?
First, check if additional analysis cameras are required. A genuine embedded tracking system only needs 4 to 5 HD cameras as signal sources for high-definition shooting. In contrast, a "pseudo" integrated system still relies on the original tracking architecture, which requires extra hemispherical surveillance cameras—typically 3 to 8—as analysis cameras in addition to the main HD cameras.
Second, look at the number of standard definition interfaces. A "pseudo" system using analysis cameras will need dedicated SD interfaces to connect the tracking system and the cameras, limiting the entire system to standard definition. Meanwhile, a real embedded system only needs a few HD interfaces for the main cameras.
Third, check if you can adjust tracking and host parameters from a single interface. A true embedded system allows users to access and adjust both the tracking system and the host through a unified interface. In a "pseudo" system, you have to enter two separate debugging interfaces—one for the tracking host and another for the recording host.
Unlike those hardware-assembled "pseudo" systems, the Yingying recording and broadcasting system embeds the image tracking software directly into the host, sharing a common hardware platform. This makes it a genuine embedded and integrated solution. The system only uses four full HD cameras for capturing the teacher's wide shot, close-up, students' wide shot, and close-up, along with built-in image analysis capabilities.
The principle is simple: the teacher’s wide shot analyzes their movement direction and sends a command to the camera to follow them in a close-up. The same logic applies to student tracking.
This embedded system offers significant advantages, using 1080P full HD images to track movements with over five times greater accuracy than systems that rely on external analysis cameras. It’s also much more streamlined and efficient. In comparison, the patchwork "pseudo" integrated systems look messy and lack the seamless integration of a true embedded solution.
