Definition of HDMI
It is a
standard that allows the transmission of high definition digital video and
multichannel digital audio uncompressed through a single cable . Companies
like
Sony , Panasonic , Philips , Hitachi and Toshibapromoted
this technology as a replacement for the scart , which
required at least two cables.
Thanks to
HDMI technology, it is possible to connect a computer (a computer) to
a television . In this way, the contents of the PC can be seen
on the TV screen. HDMI, in short, transmits video and audio between two
devices through a single cable.
The standard
HDMIconnector , known as type A , has 19 pins. The HDMI
type Cand the HDMI type D alsohave 19 pins, although they are smaller and
are aimed at connecting portable devices (smart phones, tablets,
etc.).
There is also the HDMI type B, of 29 pins, whose use is not
yet massive, designed for future screens that will have higher
resolution. Since its inception,
HDMI technology has been evolving to increase its capabilities.
This is
why it is possible to recognize several HDMI versions ,
from HDMI 1.0 (which supports a maximum speed of 4.9 Gbps) to HDMI
2.1 (48 Gbps), including HDMI 1.2 , HDMI 1.3 , HDMI
1.4 and HDMI 2.0. It is
important to mention that, although the HDMI standard does not establish a
maximum length for the cables, from a certain length the signalbegins to
attenuate.
