Get the best quality HD Audio and Video signal available to all the TV's in your home with a High Definition Network installation.
Digital Audio Video technology is literally exploding with mind blowing improvements in picture and sound quality. We've seen rapid developments over the last decade or so from Standard Definition to 720p HD, to 1080p Full HD and now 4k Ultra HD, not to mention Super UHD and Supreme UHD. (11k is currently under test.)
These improvements make for vastly improved entertainment quality, but also come with exponentially increasing demands on bandwidth speed requirements across the cables from the source device to the TV, which the old fashioned Coaxial cable TV networks in our homes can simply no longer cope with.
For those of you who love figures and numbers, Standard Definition requires around 250Mbps whereas 4K UHD now requires around 6Gbps per channel, rough 25 times more bandwidth requirement.
High Definition TV signals therefore require a very different type of installation.
HDMI Cables have limitations.
HDMI Cables are specifically designed to transport high bandwidth signals over relatively short distances, signal quality will deteriorate with longer runs depending on the quality of the hdmi cable and the bandwidth of the signal, HD, Full HD or 4K UHD. Current limitations are around 7.5m up to a maximum of 15m for top quality cables.
Quality HDMI cables can become quite expensive, which explains why most hdmi cables supplied with AV equipment are generally only 1-2m in length.
HDMI cables are quite bulky, as can be seen on the image, the end connectors are quite large which makes it virtually impossible to pull an hdmi cable through a pipe or conduit. HDMI cables, unlike many other cable types, cannot be cut to length, or re-joined, they are manufactured in specific lengths, cutting them will render them useless.
HDMI cables are therefore only useful if it's a short run between devices and it's an easy process to get the cable from the source device to the putput device.
Extending HDMI signals over longer distances up to 100m.
There will be times when your HDMI source and output device, TV, are either too far apart or running a bulky HDMI cable is not practical. This is when we make use of HDMI Extenders.
HDMI extenders enable us to convert the HDMI signal to a signal that can be run over inexpensive flexible CAT5/6/7 cables.
The quality and category of cable depends on the required distance and switching speeds.
These cable types are considerably cheaper than HDMI cables making longer runs more economical.
Cat5/6/7 cables are flexible and can be cut to length, so they are fairly easy to pull through pipes and conduits from source to output making installation somewhat easier.
By utilising good quality HDMI converters and good quality Cat5/6/7 cables we can extend your HDMI signal to 100m, which is sufficient distance for most homes and HDMI network installations.
Splitting HDMI signals from one source to many TV's, using an HDMI splitter.
Having top quality HDMI running from one source to one TV, even over a distance, is all great, but most of us have more than one HDMI TV in our homes and we want to have High Definition picture and sound quality on all our TV's.
That's when an HDMI splitter is used, with an HDMI splitter we can take an HDMI input source and split the signal to multiple HDMI TV's.
An HDMI splitter is fine as long as you are happy to view the same High Definition content on all TV's at the same time.
Switching between multiple HDMI sources on one TV, using an HDMI switch.
Most of us have a central or main TV in our homes where we have most of our High Definition sources, DStv Decoder, Blu-ray player, TV Box, Games Console etc, too many HDMI sources to plug directly into the TV all at the same time and we don't have an expensive AV receiver with multiple HDMI inputs.
In this case we will use an HDMI switch which enables us to connect multiple HDMI sources to a single High Definition input on your TV and simply select which source, or input device, we wish to view at that time.
Switching between multiple HDMI sources to multiple TV's, using an HDMI Matrix switch.
An HDMI splitter solves the problem of having multiple HD TV's, the HDMI switch solves the problem of having multiple HD Sources, but many of us have multiple HD sources AND multiple HD TV's in our homes.
We want to be able to watch whichever HD source we choose on ANY, or multiple HD TV's at any time.
An HDMI Matrix Switch is the answer.
With an HDMI Matrix Switch we can connect multiple HD source devices to numerous HD TV's and select which input signal we wish to view on which TV.
The more expensive HDMI Matrix Switches also provide for remote control of the source devices from the individual TV positions.
