What does hdmi line mean?

HDMI cable is the abbreviation of high-definition multimedia interface cable. It 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 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, there is still a lot of room for HDMI cables. This allows it to be connected separately to the DVD player, receiver and PRR with one cable. In addition, 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.

Note:

When using the HDMI cable, avoid excessive bending of the wire, such as frequent folding or twisting. Damage to the core or shielding of the line. Generally, it is bent along an arc and will not damage the cable.

Pay attention to the brightness of the gold plating on the interface. The better quality HDMI cables on the market now use 24K gold plating. This can effectively solve the problem of poor contact after the plug has been plugged and unplugged multiple times to avoid signal loss and affect the picture effect. .

Before wiring, be sure to use equipment to test the quality of the wire before it can be laid officially. When laying out the cable, wear dustproof caps on the connectors at both ends and wrap waterproof glue. Try to make a slot for the cable and do not pull it through the pipe. , do not twist or tie it, so as not to cause damage and cause the capacitance and characteristic impedance structure inside HDMI to cause attenuation and distortion of the signal.

The HDMI head is relatively fragile. It is recommended to bury more than two wires as backup when necessary. It must be isolated from strong electric wires.
