HDMI stands for High Definition Multimedia Interface. Previously, connections or older, had the digital signal from a particular source (DVD player, VCR, etc.) are converted to analog so that the TV would come, resulting in a loss of signal quality, ie, the loss of data. Today we do have HDMI. HDMI can carry a digital signal from one source to the TV (or receiver), without quality.
- HDMI video resolutions from 480i to 1080p to make, depending on the source
and the source.
- HDMI can be integrated on TV's, receivers, DVD players, Blu-ray players,
digital decoder, and more. Today this is often the case.
- HDMI also possesses a kind of protection against illigal copying, called
HDCP
- HDMI is greatly expanded in recent years, which resulted in several versions
of this connector. All the newer versions of HDMI are compatible with older
versions installed on older equipment, but you will not be able to use the
latest features of the new HDMI version. Below you can find an
overview.
HDMI 1.0 HDMI 1.0 combines a
digital video signal with a 2-channel audio signal into a single cable. This
could be between a DVD player with HDMI and a TV with HDMI.
HDMI 1.1 -This version adds the
ability to not only video and 2 channel audio through a single cable to carry,
but also the ability to surround sound like Dolby Digital and DTS to carry, up
to 8 channels (7.1 setting)
HDMI 1.2 -This version adds the
ability to carry signals to SACD. These are signs of a Super Audio CD such a DVD
player to a receiver, both with HDMI.
HDMI 1.3 -This version includes
improvements in both audio and video elements. The advent of Blu-Ray (and the
then HD DVD) This version also brings the possibility of digital bitstreams
(data streams) to implement the new high resolution audio formats like Dolby
TrueHD and DTS HD.
HDMI 1.3a Besides the
above-mentioned audio improvements, increasing 1.3 and HDMI 1.3a video bandwidth
that can be transferred from one source to the screen. This means that such
greater color depths (color palettes) can be sent and also higher resolution
than the current 1080p. HDMI 1.3 (a) is the most current version at this
time.
HDMI 1.4 HDMI 1.3 is just around
the corner and watch but HDMI 1.4 is already in the making. There are many
improvements made in HDMI 1.4, as described below;
- Network - Version 1.4 is the integration of HD video, HD audio with the same
Ethernet cable. This means that your home network, you and your Internet image
and audio signals are all integrated in a single cable.
- Return Channel Audio - The TV may soon audio signals back send this
sound to a receiver to play. This is especially useful when you're using an
analog TV tuner in your TV. Normally, you should put a cable back to the
receiver to the audio through your receiver to run to your speakers. Again,
everything again by
a single cable.
- Speed - Emerging technologies such as 2K and 4K (2000 pixels and 4000
pixels, which is a very high resolution) and 3D TV, has more bandwidth, HDMI 1.4
gives them that space. The higher speed is of course interesting, but the
technologies that we need to wait. Support for "Deep Color" (deeper color) in
HDMI 1.3 is still virtually unused.
- HD in your car - a new connector (jack) is introduced to the automotive
industry must help to HD video and audio in the car integrereren with HDMI.
- Smaller connector - there is a new, smaller 19 pin connector next to the
current connectors.
