With the advancement of science and technology, the development of television from the initial black and white, color TV, remote control, LCD, to the current multi-function intelligent, in order to comply with the pace of the times, the interface on the panel is also undergoing no small changes, the current more The more and more smart TVs have come into the homes of thousands of households, but in the real use process, in the face of a variety of dense interfaces on the panel, you are aware of their respective uses and how to correctly use them?
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
In fact, it is very simple, as shown in Figure 1:
1 is AV input, through three different colors of the line to achieve and receiver, set-top box, VCD, DVD and other devices, of which three interfaces have their own colors, the yellow interface represents the video signal, red and white interface represents the audio signal, Using the corresponding color on the AV cable to properly connect the TV to the other device, audio and video can be connected to play the content.
2 is the antenna signal input, this interface is the most familiar in the previous TV, after so many years of updating, the interface has not changed, but the way we used to receive the TV signal has changed, previously received are simulated With the elimination of analog signals, most of the signals received today are DTMB terrestrial wave digital television signals.
3 and 6 are USB interfaces, which can realize the expansion of some USB interface devices, such as cameras, mice, etc. You can also connect U disk to read and play the audio and video content inside. If you are careful, your friends should have discovered that it is also USB. Interface, why do they have different colors of the core, a blue and a black, in fact, their function is the same, but the black core of the 2.0 USB port is relatively backward, while the blue core is 3.0 The USB port is also a relatively standard interface at present, and the data transmission speed is much faster than that of 2.0.
4 is an HDMI high-definition signal interface, which can be connected with a playback device such as a computer, a set-top box, and a digital camera with the same interface, and achieves high-speed data transmission through this interface.
5 is a network cable interface. Nowadays, smart TVs are rich in functions, and more content can be obtained by connecting to the network. Therefore, this interface is indispensable for connecting to the network. However, most TVs have WIFI chips inside, and they can also connect to WIFI to implement the network. Connection.
Figure 2 is a signal input line for most of the current television configurations. It has the same function as the AV cable. It is also through the end of three different colors of male and female counterparts on the device to achieve audio and video signal transmission, but the other end of the interface into a headset-like interface, and such a TV backplane will also There is a jack like a headphone jack, which is equivalent to the previous video on the TV 2. If you use this jack to connect the device, the signal source on the TV remote control generally needs to change from one component to two components.
