Jargon Explained #1

Every industry has its own 'buzzwords' and jargon. Here we thought we would explain a couple of them, the differences, where appropriate, and their benefits and uses.

A High Definition (1080p) picture has more pixels per square inch than a Standard Definition (SD) picture, with 1920 x 1080 pixels, meaning that the picture is better.

4K (which is also known as Ultra High Definition - or UHD) has a higher resolution than 1080p High Definition. 4K resolution is exactly 3840 x 2160 pixels.  The name 4K is derived from the close to 4000 horizontal pixels.

So the more pixels, the clearer the picture.

Whilst 4K is not currently being broadcast on terrestrial channels,  Netflix  and Amazon video can stream films in 4K but a fast broadband speed is required.  Sky also has some programmes available in 4K but require a subscription.  4K DVD players are available to play 4K DVDs and they can play all your existing DVDs as well. 

Bluetooth technology is a global standard which allows a range of devices to talk to each other directly, over short distances, without having to be connected by cables.

You can be at home or in the middle of a field (if your devices are battery powered) and, as long as your two devices are less than about 10 metres apart, they can communicate.

As an aside, Bluetooth® was invented by the Swedish firm Ericsson, and the word Bluetooth comes from the Danish King Harold ‘Bluetooth’ (Blåtand) who helped unite warring factions in parts of Scandinavia.


Wi-fi is wireless communication, usually between a router (local access point) and one, or more than one, wireless device. Devices can, effectively, talk to each other, even though they are not in the same room, using the router as a ‘conduit’ to allow them to do so.

As an example, this enables you to control (with your tablet, laptop or smart phone) speakers all around your house, no matter what room you are physically standing in – as long as your devices are all in wireless range of your router.


We have products that utilise all of these technologies in our showroom, so please pop in for a demonstration and perhaps we can answer any questions you may have.
