| HDMI – High Definition Media Interface
HDMI
was created to connect high definition video sources
to digital display devices such as plasma screens, LCD
TV and video projectors, DLP and DILA video projectors,
in a secure manner with an uncompressed digital video
stream.
The connector used for the DVI system is physically
large and will only carry video and communications protocols,
not audio. What the industry really wanted, especially
Home theatre, was a connector which could carry both
audio and video signals, within a single hdmi cable
and within a small compact size. The HDMI (High Definition
Media Interface) standard was therefore developed. Freeport
Technologies have since then constantly designed
and developed a high quality range of ATC approved hdmi
cables , connectors
, Switchers , Splitters and wallpates.
Physically
the HDMI is
a 19 pin if type A or 29 pinif type B interface and
much stronger than a Scart. Another advantage is that
Long HDMI
cables can also be made, even up to 40 Metres, when
using a HDMI cable
extender. There is also the ability to run across
fibre optic converters, thus allowing cable lengths
to be theoretically extended to over 100M in custom
installations.
HDMI
has been developed as a universal interface, allowing
it to be implemented on A/V receivers, surround sound
processors, video displays (both flat panel and projectors),
digital set top boxes and DVD players. HDMI is a 5 Gbps
(5 Gigabits per second) channel, allowing uncompressed
digital video at up to 1080 (1080 lines progressive
scan) video with multi channel audio and control signals
to be transmitted from device to device. For existing
DVI equipped products,
HDMI is closely related to DVI. Various DVI-HDMI
and HDMI –
DVI converters are already available, allowing the
two standards to work seamlessly together.
HDMI
technology is here to stay and will only become
more widely adopted over the coming Years. See the HDMI
market overview page
