Question: Is HDMI the same interface as Type-Ch? Can it be universal?
Answer: HDMI and Type-C interfaces are two completely different interfaces and are not universal.
First of all, the two interface types are completely different. In addition, HDMI is an interface for transmitting sound and video signals. The Type-C interface is divided into two protocols: Thunderbolt 3 and USB 3.1. Some Type-C interfaces support the displayport full mode protocol. You can realize audio and video transmission through the Type-C to HDMI line . Some Type-C interfaces that do not support the displayport full mode protocol can only transmit data and cannot transmit sound and video signals.
. HDMI interface
I believe everyone knows something about HDMI interface. With the development and popularization of smart TVs, more and more families are connecting TV boxes and TVs through HDMI HD cables. HDMI HD cables are widely used in smart TVs, set-top boxes , projectors, etc.
HDMI represents high-definition multimedia interface and is the abbreviation of High Definition Multimedia Interface. HDMI is a high-definition video interface , which can usually be seen in mainstream laptops, LCD TVs, graphics cards and motherboards. HDMI is a digital video/audio interface technology that can transmit audio and video signals simultaneously. It is the most popular HD interface at present.
HDMI interface connection HDMI HD cable can be used to connect a variety of devices such as HDMI interface notebooks, desktop computers, set-top boxes, and other output devices connected to HDMI interface displays, TVs, projectors and other display devices. , and supports "Copy Mode", "Extended Mode" and "Game Mode".
2. Type-C interface
Nowadays, most Android phones (such as Huawei, Honor, Xiaomi , Samsung, Meizu, etc.) use Type-C interface. The Type-C interface is probably familiar to everyone. The Type-C interface has two most basic functions: "supporting forward and reverse plug-in" and "charging". The more important advantages of the Type-C interface are convenience and functional diversity. For example:
, can realize fast charging
. Under the USB PD power transmission protocol, the standard Type-C interface can be extended to 20V output voltage, 5A output current and up to 100W current transmission. Mobile phone battery life has always been a concern for users. At present, battery technology has not yet made major breakthroughs, and the introduction of fast charging technology has become a solution for various brands.
2, supports audio and video signal transmission
Type-C interface supports audio and video signal transmission, and theoretically can improve sound quality. Because the 3.5mm interface is an analog output, Type-C is a digital output, which can bring more realistic and high-fidelity audio output.
3. Can expand the capacity of mobile phone
Before, if you want to transfer photos or files from your phone to a USB flash drive, you need to transfer files to your computer for transmission, which is time-consuming and troublesome.
Phones with Type-C interface can transfer files directly to USB disk by connecting to a Type-C USB disk or an OTG adapter and easily expand the phone's capacity.
4, can achieve fast screen projection
Although many things can be done on mobile phones now, they are obviously limited by the size of the phone's screen, and without a large-screen monitor (such as a TV or projector), the viewing experience is obviously not perfect.
A mobile phone with Type-C interface can be projected onto a large screen. Connect the large screen monitor through Type-C wireless screen projector, smart docking station or Type-C to HDMI/VGA HD cable. Photos, videos and files on your phone can be projected directly onto the large screen to watch, allowing the phone to switch to the computer within a few seconds, and even split-screen operations, the large screen and the small screen will not interfere with each other.
5. It will become the overlord of the unified mobile phone interface
Type-C interface is becoming an industry trend, and it has an important relationship with powerful transmission speed, charging speed and rich expansion functions. In the future, Type-C may become the overlord of unified mobile phone interfaces.
