USB & Type C & HDMI cable:
USB cable,USB cable assemblies：
USB is the most widely used external bus standard in the field of PC, which is used to standardize the connection and communication between computer and external devices. USB interface supports the plug and play and hot plug functions of devices. With the rapid development of computer hardware, the application of USB increases the speed of data transmission between external devices. The greatest benefit of speed improvement for users is that users can use more efficient external devices. For example, with a USB 2.0 scanner, it takes only about 0.1 seconds to scan a 4m picture, and the work efficiency is greatly improved.
According to different interfaces and data cables, USB supports devices: mouse, keyboard, printer, scanner, camera, flash disk, MP3 player, mobile phone, digital camera, mobile hard disk, external optical floppy drive, USB network card, ADSL modem, cable modem and other electronic products.
Type C main features
For the needs of data exchange, t electronic devices provide USB interfaces, whether PC, tablet point, mobile phone or even display device. Almost without exception, there is a USB interface. However, due to the limitation of technical standards, the USB plug has "directionality". If the direction is wrong during insertion, either it can't be inserted, or the interface or connector is damaged. In this case, apple designed the lightning interface for its device. Since it can be inserted in both directions, users don't have to worry about the wrong insertion. In addition to Apple devices, the T industry has also introduced a similar interface standard: USB type-C,USB extenders
The trend of USB type-C was first led by apple. The advent of the new MacBook will USB type-C. This powerful technology has been brought into our vision. USB type-C is an interface specification, which is composed of type-C plug and type-C socket. Among various mobile devices and PCs, type-C has become the most promising data interface. With the gradual maturity of type-C technology, various newly launched electronic products in 2017 also chose to configure full type-C interface.
In fact, the most intuitive advantage of type-C is that it allows you to completely get rid of the trouble of inserting wires. Its innate excellent positive and negative pluggable interface design will no longer cause component damage caused by wrong insertion or mistakes. More importantly, the type-C interface has strong compatibility, so it has become a standardized interface that can connect PCs, game consoles, smartphones, storage devices and all electronic devices, and realize the unification of data transmission and power supply. For example, two display devices are closely combined through a type-C line.
In addition, type-C also supports usb3.1 standard. The maximum power supply of the standard is 100W, and the voltage and current will be increased; The coding consumption is reduced from 20% of 3.0 to 3%. In other words, users can quickly transmit data and video through type-C, or charge faster. The standard also allows users to charge other devices with their mobile phones. For the display, when using type-C for data transmission, there is no need to use another power cord to power the display, which solves the problem of messy desktop wires. Even relatively high-end HDMI and DP interfaces cannot be used.
HDMI cable
HDMI has the advantages of small volume, high transmission rate, wide transmission band, good compatibility, and can transmit uncompressed audio and video signals at the same time. Compared with the traditional full analog interface, HDMI not only increases the convenience of wiring between devices, but also provides some unique intelligent functions of HDMI, such as consumer electronic control CEC and extended display identification EDID. The HDMI cable consists of 19 wires. HDMI system is composed of HDMI transmitter and receiver. Devices that support HDMI interfaces usually have one or more interfaces, and each HDMI input of the device must comply with the specifications for the transmitting end, and each HDMI output must comply with the specifications for the receiving end. Among the 19 lines of HDMI cable, 4 pairs of differential transmission lines constitute TMDs data transmission channel and clock channel. These four channels are used to transmit audio signals, video signals and auxiliary signals. In addition, HDMI also has VESA DDC channel, i.e. display data channel, which can realize the status information exchange between signal source and receiver for configuration, so that the equipment can output in the most appropriate way.
Generally speaking, a computer with an HDMI output port is an HDMI signal source, and a TV with an HDMI input port is a receiver. After the computer and TV are connected through HDMI cable, it is equivalent to that the TV has become the second display screen of the computer.
Only one HDMI line is needed to transmit video and audio signals at the same time without multiple wires; At the same time, higher audio and video transmission quality can be achieved without digital / analog or analog / digital conversion. For consumers, HDMI technology can not only provide clear image quality, but also greatly simplify the installation of home theater system because audio / video adopts the same cable.
100% digital uncompressed, providing data transmission bandwidth up to 5Gbps, and can transmit uncompressed audio signals and high-resolution video signals. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission, which can ensure the highest quality audio-visual signal transmission. There is no need to convert pure digital image and sound (visible and audible) video and audio signals directly from the source. From the output device to the display device, the sound and image with the best digital quality are HDTV, and the bandwidth provided supports 1080p and higher resolution. Support 3D function and sound return function. Support multiple HD devices to connect more than twice the 1080i bandwidth to provide YUV color space support. Only one cable is needed to contain all HD video and audio in one cable instead of up to 8 audio and 5 video lines to reduce wiring complexity. Automatic format smart TV and AV receiver can adjust the video format supported by the video source receiving display device without consumer intervention. And output the audio and video format. The display device receives the video format and image aspect ratio from the source as it is. Consumer electronics control fully control the whole home theater from a single remote control to realize advanced functions, such as "one click playback", these functions are provided by the manufacturer to realize HDMI.
