In analog vs. HDMI, the first step you need to take is to understand
the nature of these two video interfaces. When it comes to analog, there
are many that you can choose from. They range from composite videos,
component, and S-videos.
In S-video, color and brightness are carried in different signals. They never
pass through the cable that is used to carry the audio signals. On the other
hand, composite video derives its signals from three valid sources, though they
all pass through one cable line. Component video is perhaps the most common
among the three. Video signals are divided into two components. There are also
three kinds of them, one of which is the RGB component video.
HDMI, meanwhile, the data starts out as digital and remains the same all
throughout the signal transmission. But how do these information have anything
to do with sending of data? Well, an analog interface basically works like a
modem. Everything starts out as analog, but in order to pass through the cables,
they are converted into digital signals. They are only converted back to analog,
when they reach into your video components. Thus, between analog vs. HDMI, you
can already surmise that there?s more data loss in an analog interface than in
HDMI, simply because there?s a huge tendency that quality of your signal will be
lost. HDMI has the ability to retain the digital signal all throughout the
transmission without any loss or degradation of the data.
Simpler Setup
Between analog vs. HDMI, HDMI is taking the crown when it comes to physical setup.
Since video data is transmitted through a single cable line in HDMI, you only have
one line to attend do, compared to two or more cable lines that are needed in an
analog interface.
Speed
You can never discount the speed of HDMI with regards to its transmission of data.
First of all, there?s no need to convert the signals to analog. Second, and perhaps
the most amazing fact about it, is that cables of HDMI can actually carry as much as
5 gigabits of data for every second, which, in turn, allows for a much faster
transmission of data.
Bandwidth
HDMI has more advantage over analog when you?re going to use bandwidth as basis. As a
matter of fact, it has twice the bandwidth compared to an analog interface? What does
this mean? In analog vs. HDMI analysis, it allows for more room for improvement and
future developments.
Clearly, in the war of analog vs. HDMI, the latter proves to be more cost-effective,
simpler, and of better quality. By then, hopefully, you are now ready to make your
big switch.
