What is HDMI Connector and what are the domestic and foreign manufacturers of HDMI Connector?

First, what is HDMI connector?HDMI (High-Definition Multimedia Interface) connector is a digital signal transmission interface for transmitting high-definition video and multi-channel audio signals between digital audio/video devices.HDMI connector can be connected to a wide range of digital devices, such as high-definition televisions, movie sets, computer monitors, projectors, DVD players, and digital audio receivers.The HDMI connector is a standard interface developed by several companies, first proposed by Panasonic, Intel, Sony, and Toshiba.The design of the HDMI connector allows for a dramatic increase in the speed and quality of digital signal transmission, resulting in sharper images and better sound.The HDMI connector utilizes a single HDMI connectors use a single cable to transmit high-definition video and audio signals, which are digital signals, unlike analog signals. Digital signals are highly stable and resistant to interference, so HDMI connectors can transmit higher-quality audio and video signals.HDMI connectors offer more advantages than analog interfaces. First of all, it provides higher resolution and can support high definition video such as 1080p, 4K, 8K, etc. Secondly, it supports higher frame rate, which can provide smoother video playback effect. In addition, the HDMI connector supports multi-channel audio, which can provide better audio effects.The HDMI connector is also pluggable and hot-swappable. This means that the HDMI connector can be plugged and unplugged without turning off the device, making it more convenient and easy to use. This is useful for users who need to switch frequently between different devices. In addition to the advantages mentioned above, HDMI connectors support various features such as 3D video, network connectivity, ARC (Audio Return Channel), etc. The ARC feature allows audio signals to be sent back from the TV to the audio receiver, eliminating the need for a separate audio connection cable. In addition, HDMI connectors also support Ethernet connectivity, allowing networked devices to be networked through the HDMI connector, further increasing the usability and convenience of the device.There are several different types of HDMI connectors, including Standard HDMI, Mini HDMI, and Micro HDMI. Standard HDMI connectors are the most common type and are typically used on devices such as televisions, movie cameras, and computer monitors.Mini HDMI connectors are smaller connectors that are commonly used on portable devices such as cameras and tablets.Micro HDMI connectors are even smaller and are commonly used on smartphones and other small devices.HDMI connectors were initially developed in 2002 by a couple of large electronics companies. The HDMI connector was originally developed in 2002 by several large electronics companies. The original version supported 1080i resolution video, but over time, newer versions have been added with higher resolutions and more features.HDMI connectors have also changed a lot over time, including the addition of new connector types and features, such as ARC (Audio Return Channel) and CEC (Consumer Electronic Control).HDMI connectors also come in different versions of the standards. The most current version is HDMI 2.1, which supports higher resolution and higher bandwidth to handle 8K video and 120Hz refresh rates.HDMI 2.1 also supports High Dynamic Range (HDR), Variable Refresh Rate (VRR), Adaptive Refresh Rate (ALLM), and Quick Frame Transfer (QFT), which can improve the visual effects and smoothness of games and videos.
