HDMI is the English abbreviation of high definition multimedia interface. It is a new widely used digital video / audio interface technology, high-definition multimedia interface. Kingholm has also made great efforts in HDMI products and launched a variety of products.



Based on the previous research, development and production of Beidou antenna and GPS antenna connecting line, the HDMI interface launched by golden beacon company is a special digital interface suitable for image transmission. It can be used for cable TV set-top box, DVD player, personal computer PC, TV amusement device, integrated amplifier, digital audio and TV, and 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, eight channel 96KHz or stereo 192Khz digital audio transmission, and can transmit uncompressed audio and video signals with high quality.

 

The industry association of HDMI 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. It can also transmit uncompressed HD video and multi-channel audio data with high quality. The maximum data transmission speed is 5Gbps. Version 2.1 can transmit data with a maximum speed of 48Gbps. At the same time, it does not need digital / analog or analog / digital conversion before signal transmission. It is very convenient to use. HDMI can be combined with broadband digital content protection (HDCP) to prevent unauthorized reproduction of copyrighted audio-visual content.

HDMI supports EDID and ddc2b. Therefore, devices with HDMI have the characteristics of "plug and play". The signal source and display device will automatically "negotiate" and automatically select the most appropriate video / audio format. Compared with DVI, the volume of HDMI interface is smaller, and the optimal cable length of HDMI / DVI is no more than 8m. As long as one HDMI cable can replace up to 13 analog transmission lines, it can effectively solve the problem of messy wiring behind the home entertainment system.


HDMI is pin compatible with previous DVI products, but adopts different packaging methods. Compared with DVI, HDMI can transmit digital audio signals, increase the support for HDCP, and provide better DDC optional functions. HDMI supports 5Gbps data transmission rate, up to 15m, and fully supports 1080p video and 8-channel audio signals. In addition, the HDMI signal source and the display device will automatically "negotiate", automatically select the most appropriate video / audio format, and have a fully mature adaptive mode.

Application benefits of golden beacon HDMI interface

Another advantage of HDMI is that only one HDMI line is needed to transmit audio and video signals at the same time, unlike the previous mode, which requires 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 can not only provide clear image quality, but also greatly simplify the installation of home theater system because audio / video adopts the same cable. For business development, kingholm has developed and produced a variety of HDMI interfaces and HDMI connectors of kingholm brand. After being put into the market, the response effect is very good!
