HDMI Adapters
HDMI
Adapters (High Definition Media Interface) are designed to transmit high
definition audio and video signals. These signals are then transferred between
a HDMI compatible devices such as computer monitors, video projectors,
televisions or digital audio devices. HDMI is that the latest technology
standard for making high–bandwidth connections to transmit digital information
between digital devices. Since its introduction into the consumer electronics
market in 2003 HDMI has experience a rapid rate of adoption even though there
is a lag in the move towards HD content.
For
devices with a HDMI port the connection is simply connecting a cable. However
variety of accessories are accessible to help customize HDMI connectivity to
meet special specifications with HDMI
Adapters, for better quality connection its best to use gold plated
connectors.
Portable
devices specially might have a smaller version of the HDMI port that need an
adapter. Many older products with connectors that can adapted to HDMI with the
use of adapters or converters.
What Is A HDMI Cable Used For?
HDMI
technology is used predominantly to transmit High Definition video and
multi–channel audio between digital devices over one cable. HDMI may be found
in a range currently model consumer electronics together with Plasma and LCD
screens, Blu-ray Disc players, Av receivers, set–top boxes, personal computers
(PCs), video game consoles, and Camcorders.
HDMI
is that the Digital alternative to historically used analogue signals like VGA,
Composite Video, S–Video and SCART.
How Does HDMI Work?
A
HDMI cable uses TMDS (Transition Minimized Differential Signaling) technology
to encode and transmit data between digital devices. TDMS acts to protect data
from deterioration as it travels through the copper cables to its destination.
HDMI
cables are able to transmit uncompressed information without the requirement to
convert content to AN analogue signal between devices as was necessary with
alternative older interfaces. Because no conversion is required there is no
deterioration of video quality; Images are smoother and sharper whist audio is
crisp and without distortion. This is partly why HDMI is common to be used
between HD devices.
HDMI
technology transmits all digital audio and digital video signals via the one
high–speed cable. Whilst HDMI cables permit two approach communication between
devices, HDMI ports presently only provide data to be sent within the one
direction (however the trendy HDMI, from version 1.4 onwards, allows for
upstream signals to be passed from port to port - known as Audio Return Channel).
With the correct setup, HDMI can make a significant difference in a home
theatre system.
What types of connectors can convert
to HDMI?
DVI
Digital
Video Interface (DVI) provide high quality connections between digital
displays. Both signals are digital, so a HDMI to DVI conversion cable will need
installing. However the HDMI can carry both video and audio signals, DVI can
only transport video with audio cables needed. The HDMI
Adapters can connect devices such as DTV's, plasma displays, LCD TVs and
projectors to digital sources such as DVD players, set top boxes.
VGA
Video
Graphics Array (VGA) is more complex than the DVI to HDMI due to VGA signals
being analog. They are designed for use with laptops, tablets, smartphones and
desktop computers for resolutions up too 1080p. This cable is ideal if you wish
to use Apple TV with an older VGA equipped monitor.
DisplayPort
DisplayPort
adapter allows the streaming of audio and video from a laptop or tablet to a HD
TV. Simply connect the cable to the DisplayPort of the source device and also
the HDMI connector to digital display. Another variant is Mini DisplayPort,
which supports 1080p with video mirroring and extended desktop modes.
