As a large screen in the living room, the TV has taken over the most important home entertainment functions. With the enhancement of smart TVs in entertainment, more and more interfaces have been “plugged in†to the side of the TV. You really understand all of your TVs. Interface function? For example, the common USB interface can only read and write U disk content? What is the ghost of the antenna interface? Why do TV speakers have audio output interfaces? Some common interfaces are still forgotten...
The entertainment properties of the smart TV determine its essential USB interface. Generally, the color TV will be equipped with dual USB 2.0 and a USB 3.0 interface. Besides the USB decoding and the installation of APK, the function of the USB interface is very good. We can External camera through the USB interface, so that you can QQ video chat through the TV, we can also use the USB interface external 2.4G standard equipment, such as wireless wheat, wireless game controller and so on. USB interface is widely used in consumer electronics products. The difference between USB 2.0 and USB 3.0 is that the bandwidth is different. The USB 2.0 transmission rate reaches 480Mbps, the MB is 60MB/s, and the theoretical speed of USB 3.0 is 5.0Gb/s. It can only reach 50% of the theoretical value, which is also close to 10 times that of USB 2.0.
Wifi & Lan cable network TV generally has two ways of accessing the Internet, wifi and Lan wired network. Whether it is 2.4G or 5G wifi connection is affected by the house structure and channel interference may have an impact on the signal (of which 5G channels due to the home Since other wireless signal bands are different, they will be more stable than 2.4G. Therefore, it is recommended that Lan cable network access be used for the TV connection.
HDMI input receives signals from players, set-top boxes or other devices via HDMI, which can simultaneously transmit high-frequency video and audio signals with a resolution of up to 4K. Currently, commercially available TVs are generally equipped with 2 HDMI 1.4 versions of input ports and 1 HDMI 2.0 version input port, HDMI 2.0 has a larger bandwidth than HDMI 1.4, the former is 18Gbps, the latter is 10.2Gbps, HDMI .0 ​​can transmit 4K@60P, 32-channel audio track, supports up to 1536KHz audio sampling rate, And it is more abundant in terms of function expansion. For example, the popular 4K HDR video on the market now requires the HDMI 2.0 version for transmission.
The function of the antenna input is that even if the TV is scrapped and there are many users who have not yet experienced it, the full name of the TV that is sold on the market or is currently used in your home is called the “digital all-in-oneâ€, and the digital signal is integrated in the TV. The module (DTV or DTMB, terrestrial digital television broadcasting) can decode the digital signal received by the antenna and received by the tower and fed it to the decoder and displayed on the large screen of the TV. How can we achieve this function? First, the local TV tower should issue DTMB signals. For example, Shenzhen can receive a total of about 30 sets of local TV towers in Shenzhen and Hong Kong; and secondly, you must install an antenna on the rooftop or balcony (the floor is high enough and there is no shelter). The vibrator is connected to the input of the TV antenna through the RF cable. If the signal is not strong enough, a signal amplifier can be added. Thirdly, the antenna is steered and the TV enters digital FM (into DTV tuning) to watch the terrestrial digital high-definition broadcasting program.
It is worth mentioning that, in addition to being able to accept digital signals, the antenna can also receive analog signals at the same time, which is the same as the above wiring. Only when the TV enters analog FM (enters ATV), you can watch analog TV broadcast programs. In terms of picture quality and anti-interference ability, digital television signals have many advantages over analog television signals, but they are still in the analog digital transition phase. Therefore, many television stations still use analog systems.
CAM card slot
CAM slot Many people do not know what to do, in fact, CAM slot is used to insert a secret card (including a smart card), while the CAM needs to be obtained from the cable operator, then this CAM what's the function? If we want to watch cable digital TV at home, we will install a digital set-top box provided by the cable TV operators. We can understand this. The cable digital set-top box is composed of a digital decoding module and a CAM (including a smart card). The TV is a "digital all-in-one" capable of decoding digital television signals (that is, including a digital cable digital set-top box decoding module), but because the cable digital television signal is encrypted, the CAM card slot is required to read the CAM card. The smart card information inside. In use, we only need to connect the cable digital signal to the input port of the TV antenna through the RF cable, insert the CAM card (including the smart card) into the CAM card slot, and watch the cable digital TV program through the TV FM.
Fiber-optic digital audio output High-end one-point TVs often have fiber-optic digital audio output ports. Thanks to the fiber-optic characteristics of greater noise immunity, 5.1-channel audio signals can be transmitted to the back-end decoder output to the speaker.
Analog audio outputs analog signals that can be directly connected to the speakers (preferably with volume control).
The wired MIC interface smart TV carries most of the roles of the home entertainment center. The feature-rich TV requires various interfaces to support entertainment projects, such as the K song function. In addition to the 2.4G wireless microphone technology, the cable Mic has no delay. The experience still attracts many K songs personnel, with Tianhe K songs software, living room transient KTV room!
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, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.
