What is the difference between a BNC connector and an RCA connector?

I don't know how much you know about the difference between the BNC interface and the RCA interface. There are similarities and differences between the two, each with its own advantages and disadvantages. Below, HYEC-Shanghai Huiyi Electronics will introduce you. What is the difference between the BNC interface and the RCA interface, so that you can better select and acquire these two products in the future work.

1, BNC connector

The primary role of the BNC interface is to transmit video signals, and the RCA primarily transmits audio signals. Different interfaces have different strengths and functions. In addition, due to the special planning connection of the BNC interface, there is no need to worry about the interface being loose and the touch is poor.

The BNC connector differs from the special display interface of the general 15-pin D-SUB specification connector. It consists of RGB three primary color signals and five independent signal connectors for line sync and field sync. It is mainly used to connect workstations and other systems that require high scanning frequency. The BNC connector can block the video input signal, so that the signal is interfering with each other and the signal bandwidth is larger than the general D-SUB, which can reach the best signal response.

2, RCA connector

The RCA interface completes the separate transmission of audio and video, which avoids the degradation of picture quality due to audio/video mixing disturbances. Nowadays, the most widely used interface on audio and video equipment is available on every audio and video device.

RCA is commonly known as the Lotus socket, and all TVs and DVD players have this interface. It is not specifically designed for which interface, can be used in audio, can be used in general video signals, is also a DVD component (YCrCb) socket, but the number is three. The RCA connector is by far the most common type of audio/video terminal. The two-wire connection terminal was invented by RCA Recording Company in the era of radio presentation. There is also a more old-fashioned and strange title called "Call." ” Connector.

The RCA terminal uses a coaxial transmission signal. The central axis is used to transmit signals. The outer touch layer is used for grounding and can be used to transmit digital audio signals and analog video signals. RCA audio terminals are typically labeled in pairs in different colors: the right channel is red, and the left channel is black or white. In some cases, the center and coiled channel wiring will be marked with other colors to facilitate wiring distinction, but all RCA connectors in the entire system are identical in electrical performance. In general, the RCA stereo audio cable is a group of left and right channels, each channel is a line in appearance.

The strengths and effects of both:

The primary role of the BNC interface is to transmit video signals, and the RCA primarily transmits audio signals. Different interfaces have different strengths and functions. For example, the BNC connector can make the video signals interfere with each other to achieve the best signal response. In addition, due to the special planning connection of the BNC interface, there is no need to worry about the interface being loose and the touch is bad. The RCA interface completes the separate transmission of audio and video, which avoids the degradation of picture quality due to audio/video mixing disturbances. Nowadays, the most widely used interface on audio and video equipment is available on every audio and video device.

Precautions:

There is no direct connection between the BNC interface and the transmitted video signal, and some people will mistakenly believe that the low video quality will not be the quality of the BNC interface. In fact, the picture quality and device graphics card, transmission cable, and display quality are not good. , the surrounding disturbances and other elements are related, want to maximize the role of BNC, each of the above elements must be guaranteed!

Of course, the BNC and the composite video interface are also interoperable, and can be mutually rotated through the adapter, and the signal is not lost.

After the above introduction, you should have already understood the "BNC interface and RCA interface", BNC interface and RCA interface knowledge is the basic knowledge necessary for electronic components practitioners, if you want to know more For the knowledge of BNC interface and RCA interface, please log in to our official website, update and release the bnc interface related products every day, and be satisfied with the requirements of your order.
