What Makes HDMI Different

HDMI, short for High-Definition Multimedia Interface, is a widely used standard on audio and video equipment. As a newly emerging high-tech device, HDMI enjoys great popularity among consumers. So, what makes it different form other devices and so popular among consumers?

First of all, it uses a single cable wrapped with 19 wires, which allows it to carry a bandwidth of 5 gigabits per second (Gbps). Such a bandwidth is twice as high as that needed in the transmission of multi-channel audio and video. Therefore, it is so powerful that no equipment is able to replace it in the foreseeable future.

Secondly, previous interfaces can only transfer analog signals while signals traveling through the HDMI interface are both uncompressed and all-digital. As a result, traditional interfaces would damage the quality of the original source because of the necessary conversion. However, with the HDMI interface, you will not suffer quality loss for it keeps the source signal and eliminates analog conversion. Those images and videos transferred through it can keep their integrity and without any distortion of picture quality.

Generally speaking, all traditional interfaces needed separate audio cables and thus most people had to draw support from standard audio jacks. Unlike them, HDMI is able to transmit both video and eight digital audio channels for uncompromised surround-sound with the aid of its abundant bandwidth and speed. You just need a single cable to carry though this complicated process, which greatly both simplifies the setup of the home theater system and ensures the high quality of images and videos. Therefore, it is safe to say that HDMI is distinguished from other interfaces in a lot of ways and those differences make it an ideal device for us to enjoy perfect images and videos with the least possible quality loss.
