Below, we will explain the basic knowledge of high-definition hybrid matrix in detail and comprehensively, so as to relieve your doubts.
We explain the basic knowledge of high-definition hybrid matrix in the form of question and answer
Question 1: What is a high-definition hybrid matrix switcher?
Answer: The concept of high-definition hybrid matrix switcher refers to the concept of linear algebra in high numbers, which generally refers to multiple output options in the case of multiple inputs, forming the high-definition hybrid matrix structure shown in the figure below, and each output can be used. "Short-circuit" with different input signals, each output can only be connected to a certain input, but a certain input can be connected to different outputs (simultaneously).
Question 2: What is the role of the HD hybrid matrix switcher?
Answer: The function of the high-definition hybrid matrix switcher is to use a limited display device to display more signals! Let more signals be displayed on the display device by switching.
Question 3: Where is the application of high-definition hybrid matrix?
Answer: High-definition hybrid matrix switcher has a wide range of applications. The first place to bear the brunt should be the conference room, but in a nutshell: you can use it anywhere if you understand the points 1 and 2.
Question 4: What is the classification standard for the types of high-definition hybrid matrix? What types of high-definition hybrid matrix switchers are there?
Answer: The classification standard is based on the interface, the current types are: AV (audio and video), AD, VD, VGA, DVI, HD, RGB, SDI (etc.) series of high-definition hybrid matrix switchers.
Question 5: What is the VGA high-definition mixing matrix and what is the RGB high-definition mixing matrix? What do they have in common and differences?
Answer: VGA high-definition hybrid matrix switcher: It is specially used to switch and distribute computer monitor signals. It can switch multiple signals from the input channel to any one of the output channels, and the output channels are independent of each other. Simply put, it is possible to display any one of the incoming multiple input signals to any display you specified. The "HD Hybrid Matrix" itself is a mathematical concept, and it is the abbreviation of a class of electronic products in the electronics industry. The full name is called "HD Hybrid Matrix Switcher". The word "HD Hybrid Matrix" in the HD Hybrid Matrix Switcher refers to the concept of HD Hybrid Matrix in advanced mathematics and linear algebra. Specifically in the electronic product of the high-definition hybrid matrix switcher, it generally means that there are multiple output options in the case of multiple inputs to form a high-definition hybrid matrix structure.
RGB high-definition mixing matrix: RGB high-definition mixing matrix is a high-definition mixing matrix (red, green, blue, row, field) used to switch and transmit RGBHV signals. RGB high-definition mixing matrix belongs to a kind of analog signal high-definition mixing matrix, RGBHV signal ( In the audio-visual industry, RGB signal is mainly used for display signals of large screens. It has higher quality than analog composite signals and belongs to analog component signals. The difference: VGA and RGB are basically the same in essence, and they are interface and transmission. The distance is different: RGBHV uses a BNC interface, while VGA uses a D-SUB15 head.
Question 6: What is DVI high-definition hybrid matrix and what is HD high-definition hybrid matrix? What do they have in common and differences?
Answer: DVI high-definition hybrid matrix: DVI is called Digital Visual Interface, and its appearance is a 24-pin connector. The working principle of DVI is not complicated. Simply put, the digital signal generated by the computer is directly output to the display device without any conversion. The DVI high-definition hybrid matrix switcher is specially used to switch and distribute DVI display signals. It can switch multiple DVI signals from the input channel to any one of the output channels, and the output channels are independent of each other.
HD high-definition hybrid matrix: HD digital video high-definition hybrid matrix switcher is a high-definition hybrid matrix switching device for redistributing and combining computer digital video signals. This device can switch multiple HD digital video input signals to multiple output channels. Go up any channel. It can be widely used in all occasions where HD signal distribution and combination are required. The application fields involve military industry, multimedia teaching, video and telephone conferences, finance, scientific research, meteorology and other fields.
Similarities and differences: HD is compatible with DVI in terms of pins, but uses a different package. Compared with DVI, HD can transmit digital audio signals, and adds support for HDCP, while providing better DDC optional functions. HD supports a data transfer rate of 5Gbps, which is sufficient for a 1080p video and an 8-channel audio signal. And because a 1080p video and an 8-channel audio signal require less than 4GB/s, HD still has a lot of margin. This allows it to connect the DVD player, receiver and PRR separately with one cable.
Question 7: What is the AV HD Hybrid Matrix?
Answer: The AV HD Mixing Matrix Switcher is a switching device used to synchronize the sound and the composite video signal, that is, the audio and video switcher. Its input and output interface is a standard BNC or RCA interface.
Question 8: What is a digital signal? What is an analog signal? What is the difference between them? What are the advantages and disadvantages?
Answer: ①. Analog signal: It refers to the continuous signal that the information parameter shows in the given range. Or within a continuous time interval, the characteristic quantity of its representative information can be presented as a signal of any value at any instant. ② Digital signal: Digital signal means that the amplitude value is discrete, and the amplitude value is limited to a finite number of values. Binary code is a kind of digital signal. Binary code is less affected by noise and is easy to be processed by digital circuits, so it has been widely used.
