Significant Differences Between Video Splicing Processors and Matrix Switchers
I. Working Principle
Matrix Switcher: The primary function of a matrix switcher is to switch multiple input signals to multiple display devices. Typically, the number of input signals is greater than the number of output signals. Through the switching function of the matrix, different signal images can be alternately displayed. Types of matrix switchers include VGA matrix, AV matrix, network digital matrix, DVI matrix, HDMI matrix, and hybrid matrix.
Video Splicing Processor: A video splicing processor is a specialized device for video processing and control. Its main function is to divide a complete image signal into N segments and distribute them to N video display units (such as rear projection units), allowing multiple standard video units to form a large dynamic image display. A splicing processor can support the simultaneous connection of various video devices.
II. Functional Differences
Matrix Switcher: A matrix switcher is responsible only for signal switching; it cannot process the signals or provide any effects. Its main role is to switch input signals for output, but it is unable to perform any signal processing or create effects.
Video Splicing Processor: A video splicing processor is highly functional. It not only has the basic switching capabilities of a matrix but also can perform arbitrary window opening, roaming, overlay, scene saving, and rotation. Additionally, it features effects masking, video overlay, customizable standards, intelligent system detection, and multi-screen interaction functions. This allows users to personalize the display according to their specific needs.
III. Features and Applications
Video Splicing Processor: Video splicing processors feature automatic adjustments for brightness, contrast, and color saturation, and support various edge processing techniques to ensure optimal splicing effects. They are equipped with digital multi-screen color balancing to ensure color consistency across displays. Moreover, they typically do not have an operating system, which enhances stability. Their modular design allows for flexible configuration with various input and output boards, supporting high-definition display effects. As a result, they are widely used in monitoring, command, and scheduling systems.
Matrix Switcher: Matrix switchers are primarily used for signal switching and are suitable for scenarios that require different signal sources to be displayed alternately on multiple display devices, such as displaying multiple signal sources on LCD video wall screens.
Conclusion
In summary, there are significant differences between video splicing processors and matrix switchers in terms of working principles, functional characteristics, and application scenarios. Video splicing processors are more powerful and suitable for situations that require complex video processing and display effects, while matrix switchers primarily focus on signal switching functionality and are ideal for scenarios that require alternating display of different signal sources on multiple devices.
