Each and every person who owns an HDTV or home theatre system is acquainted with an HDMI cable. If not, you must get familiar with it right away!
For beginners, HDMI means the High-Definition Multimedia Interface and the name is mainly an explanation of what the work of the cable is. The HDMI cable transfers high definition audio and video via one sole cable. HDMI cable is utilised with audio and video equipment including Blu-ray DVD players and HDTVs. The HDMI cable itself resembles a USB cable, but you have 19 wires enfolded within a single HDMI cable.
HDMI cables are perfect
The HDMI cable is able to pass on a bandwidth of 10.2 gigabits per second. The cable is a perfect, uncompressed digital source whilst the others are all parallel. An HDMI cable keeps the unique digital signal, removing any requirement for alteration. Another thing you must know about the HDMI cable is that it comes in a range of versions. The different versions of the HDMI cable comprise of HDMI 1.0, HDMI 1.1, HDMI 1.2, HDMI 1.2a, HDMI 1.3 and HDMI 1.4.
HDMI cable pricing
The other important thing you need to consider is which HDMI cable to buy. When you do your online research, you will find HDMI cables falling under different price ranges. Does the disparity in cost reflect the excellence in the HDMI cable? Will you get a cleaner picture or quicker signals with a more pricey HMDI cable? You need to make your choice based on the performance of the HDMI cable.
HDMI technology was launched in 2002 and it has revolutionised audiovisual entertainment all over the world. The interface is provided by the HDMI cable. The specialty of this cable is that it transfers digital signals without converting them to analog. The digital quality of the audiovisual signal is retained at the highest levels of quality and is then represented in your television screen. This is possible because the HDMI cable has 19 enclosed wires inside it and can support up to 8 audio channels at one time. These cables transmit digital information at the speed in excess of 10.2 gigabytes per second. This is twice the bandwidth required for transferring high quality audiovisual signals. Discussed here are some features of HDMI.
Outstanding features of HDMI cables
The five different types of HDMI cables available in the market are standard HDMI, standard HDMI with Ethernet, automotive HDMI, high speed HDMI and high speed HDMI with Ethernet. Each of these cables supports different functionalities.
The standard HDMI cable transmits 1080i and 720p video quality signals. It improves resolution to a great extent. The standard HDMI cable can be used for DVD players, satellite television and digital broadcasting etc. The Ethernet transmitter counterpart of the standard HDMI cable is used to share internet at high definition. Automotive HDMI cables are used for high performance internet transmission. They are made from highly specialised materials. Resolutions in excess of 1080p are best viewed through the high speed HDMI cables. The high speed HDMI cable with Ethernet is the most advanced version. It can support the highest resolution along with 3D and allow the transmission and sharing of the internet without the need for an extra cable.
HDMI is the acronym for High Definition Multimedia Interface. It is actually a description of what the HDMI cable is used for. The cable provides the interface for high speed transmission of audio and video. The cable is used with audiovisual equipment such as HD televisions and Blu-ray DVD players. It looks similar to a USB cable, except for the fact that 19 individual wires are wrapped inside it.
HDMI cables are capable of transmitting 10.2 gigabytes per second. This is twice the normal bandwidth necessary for transmission of audio and video signals. HDMI is the only one mode which provides clean and uncompressed digital information. The other methods are analog.
What makes HDMI special?
Analog signal transmission picks up digital data from a source and transmits it after converting it to analog data which is again converted to digital, before being displayed on screen. This triple conversion of the data causes it to break and the resultant final display of audiovisual signals is not clean. The HDMI cable keeps the original digital signal intact and eliminates the need for conversion. It gives you the clearest, sharpest images and audio.
HDMI cables are available in different versions such as HDMI 1.0, HDMI 1.1, HDMI 1.2, HDMI 1.2a, HDMI 1.3 and HDMI 1.4 etc. They all look identical and have the same connectors. Each newer version can accommodate data transmission of the lower levels. This means that you will not go wrong if you buy the HDMI cable of the latest version. All your equipment will work well, no matter what version of the HDMI cable you use.
Any older audio/video equipment you have will work together with any newer equipment regardless of the HDMI cable version you use.
HDMI is an acronym for High Definition Multimedia Interface. It is an interface provided by HDMI cables. With the ability to transfer data at a speed of 10 gigabytes, these are one of the fastest data transmission cables available. They are used to transmit digital audiovisual signals from their sources to our television screens.

These cables transmit audio and visual data in digital format. HDMI cables are compatible with any appliance as they can transmit digital which gives you amazing picture quality.
How do HDMI cables work?
HDMI cables use the core transmission functionality through a twisted pair of wires. As the signal is being passed via the cable to the device, it is converted and encoded. The electronic device emits a signal that is digital or analogue in format. This is completely dependent on the quality of the electronic device. The DVD player then receives the signal through the cable to the TV through one of the pairs of wires. The TV then receives both the previous and the inverse image signal, which is transmitted through the second wire. The electronic device checks the difference and uses this to give you an excellent image quality.
The HDMI cable, thus optimises the output of your electronic device giving you only the best picture. With HDMI cables there is no need to have long wires because the longer your cable, the higher the chance of signal degradation happening.
Take a pick from the different versions of HDMI cables that are available in the market. It is advisable to use the appropriate cable for the device you have to get the best viewing quality, whether it is for your HD TV or gaming console.
