What Is The HDMI?

HDMI full name in English is "High Definition Multimedia Interface", meaning the Chinese High-Definition Multimedia Interface.

HDMI interface can provide up to 5Gbps data transmission bandwidth, can send uncompressed audio signal and high-resolution video signals. Also no need to send the signal before D / A or A / D conversion, can guarantee the highest quality audio and video signal transmission. HDMI and DVI on the pin-compatible, but with a different package. Compared with DVI, HDMI can transmit digital audio signals, and increased support for HDCP, providing a better DDC optional. HDMI support 5Gbps of data transfer rate, can transmit 15 meters far enough to deal with a 1080p video and an 8-channel audio signals. but because of a 1080p video and an 8-channel audio signal needs less than 4GB / s, therefore, HDMI there is great margin. This allows it to be connected with a cable DVD player, receiver and PRR. In addition, HDMI support EDID, DDC2B, so has the HDMI device has a "plug and play" feature, the signal source and between the display device will automatically "consultation", automatically select the most appropriate video / audio format.

End of the year 2002, high-definition digital multimedia interface HDMI 1.0 standard promulgated. HDMI and DVI on the pin-compatible, but with a different package.

Application of the benefits of HDMI is: only one HDMI cable, they can also transmit audio and video signals, unlike now need to connect multiple wires; the same time, wireless for D / A or A / D conversion, can achieve higher audio and video transmission quality. For consumers, HDMI technology not only provides a clear image quality, but the audio / video using the same cable, which greatly simplifies home theater system installation.
