HDMI cable, short for high definition multimedia interface wire, can transmit high quality uncompressed hd video and multichannel audio data with a maximum data transmission speed of 5Gbps. At the same time, digital/analog or analog/digital conversion is not required before signal transmission, which can ensure the highest quality of video and audio signal transmission.
HDMI cables support a data rate of 5Gbps and can transmit up to 30 meters, enough to handle a 1080p video and an 8-channel audio signal. Because a 1080p video and an 8-channel audio signal require less than 4GB/s, the HDMI cable has plenty of room. This allows it to connect the DVD player, receiver and PRR separately with a cable. In addition, HDMI supports EDID and DDC2B. Therefore, devices with HDMI have the characteristics of "plug and play". There will be automatic "negotiation" between signal source and display device, and the most suitable video/audio format will be selected automatically.
