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.
