HDMI cables are digital connector interfaces which have rapidly replaced the traditional analogue cables that have been around for years. Examples of these near-obsolete cables include VGA, S-Video and SCART cables.

The reason that HDMI has taken the electronics world by storm and replaced other cables is that are able to carry both audio and video signals in one cable, so there is no need for separate cables.

Here are few other facts you should know about HDMI cables:

There have been several versions of HDMI cables released over the years. Each has been revised in order to launch a new, more advanced cable. So, for example, the HDMI 1.0 cable released in 2002 was very basic, whilst the latest versions, HDMI 1.4 cables, have support for even advanced technologies such as 3D TV.

The standard HDMI cable has 19 pins. However, new connector types have been introduced for HDMI cables to allow them to be used on the move, or even in vehicles. Whilst the mini-connector has the same 19-pin configuration but in a smaller size, the Type B connector, for use with high-resolution future displays, has 29 pins.

HDMI cables are very advanced in the technologies they are able to support, but they are also very useful on a practical level. As they carry both audio and video signals, they allow homeowners to connect up their home entertainment systems using half as many cables.

In the first part of this guide, we looked at a couple of essential facts you should know about HDMI cables. Let’s take a look at a few more:

HDMI cables can be used to connect a wide range of portable devices, as well as the traditional components of home entertainment devices. These portable devices include digital cameras, video cameras, laptops, desktop computers, mp3 players, tablet computers and smart phones.

HDMI 1.4 cables offer new and exciting features. These include support for 3D-enabled components, an Ethernet channel and an Audio Return Channel.

All HDMI cables have a feature known as Consumer Electronics Control (CEC). This enables users to control two or more CEC-enabled devices or boxes using just the one remote control.

There are three main types of HDMI cable. These are standard HDMI cables, high speed HDMI cables and Automotive Connective Systems.
