What is HDMI cable
HDMI cable, short for high-definition multimedia interface cable, can transmit uncompressed high-definition video and multi-channel audio data with high quality at a maximum data transmission speed of 5Gbps. At the same time, no digital/analog or analog/digital conversion before signal transmission can ensure the highest quality of audio and video signal transmission.
HDMI cable supports 5Gbps data transmission rate 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 require less than 4GB/s, HDMI cables have plenty of leeway. This allows it to connect the DVD player, receiver and PRR with a single cable. In addition, HDMI supports EDID, DDC2B, so devices with HDMI have a "plug and play" feature, the signal source and display device will automatically "negotiate", automatically select the most appropriate video/audio format.
