HDMI – the categories and their purposes

With the launch of the HDMI 1.4, there five HDMI cable categories, each designed to achieve different performance.

To make things less confusing, HDMI cables will be categorised by type.

Standard HDMI Cable

This HDMI cable is best for most home use, and is able to transmit 1080i or 720p video, which are most frequently used by cable, satellite, HD, and premium DVD players.

Standard HDMI Cable with Ethernet

This cable provides 720p or 1080i video resolution, but also has an HDMI Ethernet Channel, specifically needed for networking.

Automotive HDMI Cable

This is for vehicles with onboard HD video systems. The difference here lies in the cables ability to deal with vibration and temperature change without affecting quality.

High Speed HDMI Cable

High Speed HDMI can handle video resolutions of 1080p and more, as well as even more sophisticated technologies such as 3D. We suggest that you choose this cable if you are using it for such purposes or connecting your 1080p display to a 1080p content source, such as a Blu-ray Disc player.

High Speed HDMI Cable with Ethernet

As with the relationship between standard HDMI and standard HDMI with ethernet, High speed HDMI works in the way. There is an extra data channel for device networking.

High Definition Multimedia Interface (HDMI) – A basic information guide

HDMI cables are carriers of digital audiovisual signals. They establish a digital connection between a HD device and the source of digital data. The digital information is uncompressed and does not undergo a conversion process before being displayed on the screen. HD DVD players, HD televisions and HD audio systems are electronic devices which have been upgraded to accommodate this technology.

HDMI cables – Features and specifics

HDMI cables are exclusively designed to keep picture and sound quality intact. The HDMI cable is a set of 19 sub cables which provide twice the bandwidth needed for transmission of audio and video signals. They can effortlessly transmit 10 gigabytes of digital audio and video per second.

Every version includes three types of connectors. Type A and C have nineteen pins for supporting all HDTV formats. A type B HDMI cable has twenty nine pins and has capacity for higher video resolutions such as WQSXGA.

After its introduction in 2002, the HDMI technology has undergone many upgrades – HDMI 1.0, HDMI 1.1, HDMI 1.2, HDMI 1.2a, HDMI 1.3 and HDMI 1.4.

HDMI 1.4 is the latest and most advanced version among the list mentioned above.

HDMI offers audio and video transmission without the slightest disturbance or signal loss.

High Definition Multimedia Interface (HDMI) – Facts and FAQs

HDMI makes use of digital signal conversion technology and not analogue video signals.

What are the advantages of HDMI over other mode of signal transmission?

An HDMI cable will last for years and will be able to be used for all HD technology upgrades in the future. Every new audiovisual device has HDMI cable slots and connectors to accommodate the technology as HDMI gives the best quality audio and visual signals. HDMI cables can compress 8 audio channels into one cable. Even if the technology is upgraded in the future, you will not need to buy new cables as they are backward compatible.

What are the different versions of HDMI?

HDMI was released in 2002 and since then it has undergone several upgrades. HD technology has undergone some popular upgrades such as Dolby True HD, DTS HD Master audio support, super audio CD support and DVD audio support.

Will my existing HDMI cables work for newer versions of the technology?

HDMI as a technology may get upgraded; however the cables do not need to be. The HDMI cable is the most advanced data transmission cable in the world today and has the capacity to handle future technology upgrades.

Does the HDMI cable need to be thicker the longer it is?

Long HDMI cables can run over a distance of 50 to 100 feet. The wire gauge is thicker for these purposes and hence the cable will also have to be thicker. Thinner cables over long distances do not give high quality audiovisual outputs.

What’s the right HDMI cable for you?

Because of the way HDMI has been tested to date, it’s very confusing for customers. HDMI cables are tested to certain specifications, which include 1.1, 1.2, 1.3 and so on. These numbers mean very little to customers so HDMI is increasingly being categorised by what category is applicable for, for example, automotive HDMI, standard, HDMI, and High Speed HDMI. We cover more the specific qualities of each of the DMI categories in the next article.

However, most people require HDMI for domestic entertainment use, and in such instances, standard HDMI is more than ample. Standard HDMI transmits 1080i or 720p video, which are most frequently used by cable, satellite, HD, and premium DVD players.

In some cases, in the home, for entertainment purposes, High Speed HDMI is more beneficial. If you are looking to utilise 3D, for example, we would recommend you use High Speed HDMi cables. However, there is also substance in the argument for future proofing your HDMi needs by buying High Speed cables.

A simple way to better entertainment – HDMI leads

Whether you buy a Plasma TV or a gaming console, most consumer electronic devices like computers, Blu-ray players, DVD players and set-top boxes come with a HDMI port. This port provides enhanced sound and visual connectivity quality. HDMI leads use one single cable to transmit all your audio and video signals. It uses technology that is far superior to its previous analogue form. HDMI leads can also accommodate any future advances or upgrades in HDMI technology. This means that using HDMI leads you can connect your new TV to your old computer and send high quality and video signals easily.

The technology behind HDMI leads

A very important thing to be kept in mind while using HDMI leads is that the quality of the signal received is affected by the distance between the items. Using a good quality HDMI cable is therefore important. If you use a good quality cable you will get better sound and picture resolution. Similarly, if you use a cheap cable then the sound and video may be compromised. A normal HDMI lead supports 8-channel audio and video data transmission; therefore you can use one cable for audio and video, instead of two.

So if you use a simple HDMI lead, not only will you enjoy your entertainment devices with renewed pleasure, as the quality is obviously better, but there is very little that you will have to tweak in the future. HDMI cables are easy to install and even better to use.
