Kinghelm HDMI interface functions and advantages

HDMI is the English abbreviation of (High Definition Multimedia Interface), which is a brand-new digital video/audio interface technology high-definition multimedia interface that is widely used by everyone. Kinghelm Company has also made efforts in HDMI products and launched a variety of products.

Based on the previous development and production of Beidou antenna and GPS antenna cables, Jinhangbiao Company launched the HDMI interface, which is a dedicated digital interface suitable for image transmission. It can be used for cable TV set-top boxes, DVD players, personal computers, TV game consoles, integrated amplifiers, digital audio and televisions. It can transmit audio and image signals at the same time. HDMI can not only meet the resolution of 1080P, but also support digital audio formats such as DVD Audio. It supports eight-channel 96kHz or stereo 192kHz digital audio transmission, and can transmit uncompressed audio signals and video signals with high quality.

The HDMI industry association released HDMI version 1.0 standard on December 9, 2002, and HDMI specification version 1.4a on March 4, 2010. HDMI can transmit audio and video signals at the same time, and can also transmit uncompressed high-definition video and multi-channel audio data with high quality. The maximum data transmission speed is 5Gbps. Version 2.1 can transmit data at a maximum speed of 48Gbps. At the same time, there is no need to perform digital/analog or analog/digital conversion before signal transmission, making it very convenient to use. HDMI can be paired with Broadband Digital Content Protection (HDCP) to prevent unauthorized copying of copyrighted audio and video content.

HDMI supports EDID and DDC2B, so devices with HDMI have the characteristics of "plug and play". There will be automatic "negotiation" between the signal source and the display device to automatically select the most appropriate video/audio format. Compared with DVI, the HDMI interface is smaller, and the optimal cable length of HDMI/DVI does not exceed 8 meters. Just one HDMI cable can replace up to 13 analog transmission lines, effectively solving the problem of messy and tangled connections behind home entertainment systems.

HDMI is pin-compatible with previous DVI products, but uses a different packaging method. Compared with DVI, HDMI can transmit digital audio signals and adds support for HDCP while providing better DDC optional features. HDMI supports a data transmission rate of 5Gbps, can transmit up to 15 meters, and fully supports 1080p video and 8-channel audio signals. In addition, HDMI signal sources and display devices will automatically "negotiate" to automatically select the most appropriate video/audio format, with a fully mature adaptive mode.

Application benefits of Golden Navigation HDMI interface

Another advantage of HDMI is that only one HDMI cable is needed to transmit audio and video signals at the same time, unlike the previous mode that required multiple wires to connect; at the same time, due to wireless digital/analog or analog/digital conversion, higher audio and video transmission quality can be achieved. For consumers, HDMI technology not only provides clear picture quality, but also greatly simplifies the installation of home theater systems because audio/video use the same cable. For business development, Kinghelm Company has developed and produced a variety of HDMI interfaces and HDMI connectors under the Kinghelm brand. After being put into the market, the response has been very good!
