HDMI cables – A brief user guide

HDMI cables transmit digital audio and video signals between different electrical components. Here are some ways in which you can use HDMI cables:

Using HDMI cables

In the past, using standard video connection cables was rather a difficult task. It was in fact difficult to set up a regular entertainment system. This is not the case any more, as HDMI cables contain both, video as well as audio cables in one neat cable.

All you have to do is plug in the HDMI cable to any one of your electrical components. This can be any device from a Blu-ray player to a DVD player. Ensure that you connect one end of the cable to the TV and the other to the device. This step can be repeated for all your electronic devices.

After the set-up process, you can change the source on the receiver to use any input device you wish as many new HD TVs come with many HDMI ports. HDMI cables are thus simple to use as well as set up.
HDMI cables form an important part of a new home cinema system. Follow the above steps and set up your HD device in only a few minutes.

HDMI cable – Tips to check it’s working ok

HDMI cables are a must for HD picture output. These cables send both HD audio as well as video signals between electrical AV devices. It is unlikely that you will experience any sort of playback issues while using this cable. However, if you do face a problem then you can usually fix it quite simply.

Make sure you choose the right input channel on your TV

Some TVs will automatically change the input channel when they detect a new source, whereas on some you will have to use the remote to choose the input source. Make sure you have the right input source selected before proceeding with the following steps.

Check the cable

You should first check the HDMI cable and see if it is plugged in the appropriate connection port. One of the cable sockets should be inserted into the TV whereas the second socket should be connected to the source device. The signal will not be transmitted properly if you have not plugged in the cable appropriately.

Check the metal connector

If the cable is plugged in correctly, you should then unplug the HDMI cable from both pieces of equipment. Sometimes this connector gets clogged with dirt and dust particles. This will thus interfere with the transmission of signals and affect the picture quality. Blow out any dirt of dust particles from the connector socket.

Choose another HDMI port

If the above two options fail, try using another port when plugging in the HDMI cable. The HMDI port might be the reason for the faulty transmission. It can sometimes be damaged due to constant use. Changing the port can thus solve this problem.

The enhanced features and functionality offered by HDMI 1.4

HDMI cables are now used for a high-quality multimedia experience when connected to audio visual sources. These sources include HDTVs, Blu-ray players, PlayStation and other gaming devices. HDMI 1.4 is the latest version of HDMI. Unlike its predecessors, HDMI 1.4 offers massive improvements in areas like resolution, network capability and automotive connection.

The four new features of HDMI 1.4

Audio return channel:
HDMI 1.4 offers a completely new audio return channel. As the audio and video signals are carried via a single cable, it reduces the need of having a number of different cables.

HDMI Ethernet Channel:
The latest version of HDMI cable adds a data channel. This also helps to ensure a rise in bi-directional communication speed. Additionally, this data channel makes devices instantly ready for Internet Protocol-based applications. HDMI 1.4 also allows the ability to share an internet connection with other HDMI devices. Thus, the need to have a separate cable is completely eliminated.

Supports higher resolutions:
The HDMI 1.4 specification allows users to play high resolution files (up to 4k x 2k). It also allows HDMI devices to offer the required support for transmitting content at a resolution that is similar to most digital cinemas.

3D resolution and common format:
HDMI 1.4 standardises the I/O portion of the system. So, in case there is any problem in playing different 3D formats, HDMI 1.4 cables can take care of it. Moreover, the resolution is specially defined to allow high-definition devices to play files with dual stream. Resolutions of up to 1080p are supported by HDMI 1.4 cables.

What are the features and characteristics of HDMI leads?

High definition multimedia interface is the full form of HDMI. It is a special transmission technology enabled by an HDMI cable which is capable of transmitting audiovisual signals at speeds in excess of 10.2 gigabytes per second.

HDMI leads – what are they?

HDMI leads are emerging as the most preferred form of HD connective devices. You will find scart leads on most HD devices, but these leads are being replaced by HDMI. HDMI leads reduce the number of cables at the back of your HD devices.

Modern electronic entertainment devices all have HDMI ports installed. The leads look very similar to USB cables.

The HDMI interface does not convert digital signals into analogue before displaying them on the television screen. Since HDMI leads have the highest capacity for digital data transmission they can accommodate up to eight channels of audio within one cable.

What else should you know?

HDMI leads have different specifications and each one is optimised for a particular setting. They all have different digital data capacities and the prices vary according to this. Cheap HDMI leads may not necessarily offer great performance as they may be easily affected by RFI and EMI related disturbances. Always buy HDMI leads from reputable manufacturers.

Buying an HDMI cable? Here is what you need to know

High Definition Multimedia Interface is the full form of what we all know as HDMI. It is a special type of connectivity provided by a cable which allows transmission of audiovisual signals at speeds in excess of 1.2 gigabytes per second. The HDMI cable has 19 individual cables enclosed within it. It can support 8 audio channels at one time and provides crystal clear digital entertainment. However, HDMI has undergone several upgrades since its inception and each upgrade offers a different functionality. If you want to buy an HDMI cable, you need to know the connectivity options in your devices. The following discussion will enable you to choose an HDMI cable.

What are the specifications and support capabilities of a HDMI cable?

All HDMI cables in the market may not necessarily support the devices you have. Every HD device has its own HDMI specification.

You will come across two major variants of the HDMI cable. Category I cables are used for standard HDMI connectivity and Category II HDMI cables can perform the standard functions at much higher speeds.

If you want to connect your HD devices at distances of more than 50 feet then you will need a long HDMI cable. The longer the HDMI cable you choose, the more chance the signal will diminish as the cable may not be able to transmit audiovisual signals across these distances and hence you may need to buy an equalizer and a signal booster.
