Basic introduction to HDMI cable
- Apr 03, 2018 -

The HDMI line is an abbreviation for High-Definition Multimedia Interface Cable. It enables high-quality transmission of uncompressed high-definition video and multi-channel audio data. The maximum data transmission speed is 5 Gbps, and it is not necessary to perform digital/analog or analog/digital signals before transmission. The conversion can guarantee the highest quality video signal transmission.

The HDMI line supports a data rate of 5Gbps and can transmit up to 30 meters, enough to handle a 1080p video and an 8-channel audio signal, and because a 1080p video and an 8-channel audio signal require less than 4GB/ s, so the HDMI cable has a large margin, which allows it to use one cable to connect the DVD player, receiver and PRR, respectively.

In addition, HDMI supports EDID, DDC2B, so HDMI-equipped devices have "plug-and-play" features, and the signal source and the display device will automatically "negotiate" and automatically select the most suitable video/audio format.
