Bnc cable | How to use BNC and RCA interfaces accurately in the audio and video field?
25 Mar 2022

There are many interfaces in the audio and video field. As a very common video and audio transmission interface, it has its own advantages in equipment transmission. 1. BNC connector Coaxial Cable Adapter, BNC Male/RCA Female Coaxial Cable Adapter, BNC Female/F Male The BNC connector is different from the special display interface of the ordinary 15-pin D-SUB standard connector. It consists of RGB three primary color signals and five independent signal connectors for line synchronization and field synchronization. It is mainly used to connect workstations and other systems that require high scanning frequency. The BNC connector can isolate the video input signal, so that the interference between the signals is reduced and the signal bandwidth is larger than that of the ordinary D-SUB, which can achieve the best signal response effect. 2. RCA connector RG59A coaxial cable, RCA male/BNC male 3-wire RCA audio/video cable, RCA male/male The RCA connector is by far the most common audio/video terminal, commonly known as the lotus socket. It is not specifically designed for any kind of interface, it can be used for both audio and ordinary video signals. The RCA terminal adopts the method of coaxial transmission of signals, the central axis is used to transmit signals, and the contact layer around the outer edge is used for grounding, which can be used to transmit digital audio signals and analog video signals. RCA audio terminals are generally marked in pairs with different colors: red for the right channel and black or white for the left channel. In some cases, the center and surround channel cables are color-coded to facilitate wiring distinction, but all RCA connectors throughout the system are electrically identical. Generally speaking, RCA stereo audio cables are a group of left and right channels, and each channel is a line in appearance. 3. The advantages of both The main function of the BNC interface is to transmit video signals, and the RCA interface mainly transmits audio signals. Different interfaces have different advantages and functions. For example, the BNC connector can reduce the interference between video signals and achieve the best signal response effec

Video game cables As technology has advanced, so have the cables required for equipment. Even though many manufacturers are moving to wireless solutions, you may still need some form of cable at all times. This is especially true for video equipment. TVs, monitors, and peripherals require a variety of cables and connections to function properly. So, what's the difference between them and which ones do you need? Let's take a look at some of the most popular types of video cables and when you need to use each. VGA cable VGA stands for Video Graphics Array. The connection was developed by IBM in 1987, making it one of the oldest video connections still in use today. It is widely used in video cards, televisions, computer monitors and laptops. VGA can support a maximum resolution of 640x480 with 16 colors, although you can increase the color to 256 by lowering the resolution to 320x200. This is called mode 13h and is usually used when booting the computer into safe mode. Mode 13h was frequently used in video games in the late 1980s. VGA is capable of transmitting RBGHV video signals, including red, blue, green, horizontal sync and vertical sync. The iconic blue adapter has screws on both sides to secure the connection. The socket consists of 15 pins arranged in three rows of five. It's since been surpassed by digital connections like HDMI and DVI, but it's still popular thanks to the rise of nostalgic gaming and its inclusion in cheap monitors and monitors. RCA cable RCA leads are one of the most intuitive video cables. Red, white and yellow plugs are synonymous with audiovisual equipment produced in the 1990s and early 2000s. It's also the primary connection for many consoles, including the Nintendo Wii. Most TVs no longer support RCA inputs. DVI cable The Digital Display Interface Working Group introduced the Digital Visual Interface (DVI) in 1999, the successor to the VGA cable. A DVI connection can transmit uncompressed digital video in one of three different modes: DVI-I (integrated) combines digital and analog in the same connector. DVI-D (Digital) only supports digital signals. DVI-A (analog) only supports analog. DVI-I and DVI-D can be in sin
