Use HDMI cables for excellent audio and video quality

HDMI enables the high quality transmission of digital information from one device to another. HDMI or the high definition multimedia interface is now an essential line of communication between all your digital devices. They are a superior alternative to the traditional S-video and coaxial cables. To understand HDMI cables, you first have to know what they are not.

S-video, coaxial and HDMI cables

A little peek at the back panel of your TV or DVD player will reveal a tangle of cables. You might see an S-video cable connected to its roundish connector, or a coaxial connection, which has a metal connector that screws in a pin. Coaxial connections are also known as aerial connectors, and are used to connect radio frequencies and cable television. Both these cables allow you to connect your media using an analogue transmission. The downside of these cables are that not only is the transfer quality inferior to HDMI, but they also clutter your space.

An HDMI cable is a must when using an HDTV. The high quality digital signals are lost when you do not use an HDMI cable for an HDTV.

Another edge that HDMI cables have is that there is just one cable for both audio and video. You can minimize all the cable clutter behind your devices.

HDMI 1.4 cables – Bring your TV to life

Recent times have seen a revolution in high definition media. New digital devices like Blu-ray players, high definition LCD and LED TVs, laptops and their 3D counterparts all use HDMI cables for best output performance. High definition media interface or HDMI ports are now a standard fixture in all new generation devices. To connect these devices we use HDMI cables. These come in many types, from cheap cables to gold plated HDMI cables.

How does HDMI work?

A full HD output screen has 1080 lines of pixels. These pixels are scanned one after the other repeatedly. This is known as progressive scanning and can be done only when the image data is transferred very quickly. The old audio-video leads and SCART cables cannot transmit all this data. The old dual lead cables, which had separate leads for sound and picture, can carry only analogue signals. Hence the digital data had to be first converted into analogue and then converted back to digital on reception by the output device. This time lag can cause your picture quality to reduce and can also introduce noise.

The next generation cables

HDMI 1.4 cable can transfer digital data at high speed. This is due to the fact that an HDMI cable is capable of transferring digital data directly without analogue conversion. It is also a single lead for both audio and video, making it hassle free and saving space. It is ideally suited to the latest 3D LCD TVs, which bring the latest picture viewing technology to your living rooms.

Enjoy high definition viewing

HDMI cables can be used to connect anything; right from computers and DVD/Blu-ray players to PS3 gaming consoles.

HDMI devices were first introduced to the consumer market in 2003 when HD televisions were first introduced.

Connecting HDMI cables

HDMI cables connect to media sources like cable boxes, personal computers, DVD players and video gaming consoles and also radios and televisions. They carry digital signals from one device to another.

HDMI cable layout

Generally HDMI cables have 19 pins, each one having a different function. Nine of the pins convert the data received into a digital format while three of them are used to channelise data. Three other pins are used to continuously convert and transmit data.

Transmission of data

HDMI cables have a pair of twisted wires which first convert the data and encode it to ensure that the data does not get degraded in the course of sending it from one device to another. The other device receives the data sent via the cable and decodes the information. The cable relays two types of data; one wire sends the data in a true form while the other wire sends data in the inversed form. The receiving device decodes both sets of data and compares the two to check for any degradation and the better of the two is used for the output.


There is no specific length of an HDMI cable. The cable should not be too short as it might damage your devices by pulling on it. But a long length of a cable can be prone to signal degradation.
