HDMI cable is the abbreviation of high-definition multimedia interface cable, which can transmit uncompressed high-definition video and multi-channel audio data with high quality, and the maximum data transmission speed is 5Gbps. At the same time, there is no need to perform digital/analog or analog/digital conversion before signal transmission, which can ensure the highest quality video and audio signal transmission.

The HDMI cable supports a data transfer rate of 5Gbps and can transmit up to 30 meters, which is enough to handle a 1080p video and an 8-channel audio signal. And because a 1080p video and an 8-channel audio signal requires less than 4GB/s, the HDMI cable has a lot of headroom. This allows it to connect the DVD player, receiver and PRR separately with a single cable. In addition, HDMI supports EDID, DDC2B, so the device with HDMI has the characteristics of "plug and play", and "negotiation" will be performed automatically between the signal source and the display device to automatically select the most suitable video/audio format.
