The Ethernet connectivity feature enables internet sharing and the audio return channel is for upstream audio transmission.
Specifications of HDMI 1.4
The HDMI cables perform enhanced data transmission functions now. The standard level HDMI data cable transmits digital information at 1080i/60. The high speed version of the same cable can accommodate data at rates higher than 1080p and supports 3D. As mentioned earlier, Ethernet connectivity has been added to enable internet sharing without an extra cable. The automotive HD cable attaches electronic devices to installed HDMI ports in cars.
The HDMI Ethernet channel enables bi-directional communication. The devices connected across this channel can transmit data at 100 megabytes per second. Every application is instantly available at the required internet protocol address. In the past, an extra cable was required for upstream audio processing and playback. HDMI 1.4 has now incorporated the audio return channel, which enables those very functions without the need for an extra cable.
HDMI 1.4 is the latest in the technology and is revolutionising the way we watch television and experience these entertainment systems.
High definition multimedia interface or HMDI cables are known for their HD picture quality. They can easily transmit digital data between electrical components like DVD players, Blu-ray players and HD television sets. HMDI cables also offer clear and superior audio as well as video signals via a single cable.
Here are some key points to consider while buying HMDI cables:
Not many people are aware that HMDI cables are available in different versions. Currently, HMDI cables are available in five different types of specifications as follows:
HMDI 1.3 versions are meant for the testing specification. Moreover, they do not provide any improved functionality. If you are looking for improved functionality then you should opt for the 1.4 version. Version 1.4 also consists of an Ethernet channel and can be used along with IP enabled devices.
The benefits of using version 1.4 do not end here. HMDI version is also known to support 3D and offers great resolutions of up to 4096 X 2160. Version 1.4 is better known as a High Speed HMDI cable with Ethernet.
Ferrite EMI suppressors
It is recommended that you look for HMDI cables enabled with Ferrite EMI suppressors. These suppressors are a must for reducing the impact of electro-magnetic interference. They are a round-barrel shape and are present at either ends of the cable.
Ensure that you purchase HMDI cables of 7.5m in length. This way, you can enjoy the pictures without any loss in quality. Keep these important points in mind and make an informed decision.
HMDI cables, also known as a High Definition Multimedia Interface, enable a digital connection between the TV set and HD devices such as DVD and Blu-ray players. HMDI cables also eliminate any kind of cable clutter to the TV set. Thus, the viewers can enjoy a HD viewing experience. This is the reason why HMDI cables are widely used in home entertainment systems.
Functions performed by HMDI cables
An HMDI cable transmits digital signals from the television sets to other components. This is done without digital to analog conversions, unlike other cables. HMDI also eliminates the need for separate sound components as it amalgamates video as well as audio signals. It results into better connections between the TV set and other components.
What are the different types of HMDI cable?
HMDI was introduced in the year 2003. Back then, the only version, HMDI 1.0 was available in the electronics market. Many variations of HMDI cables have been introduced since then. Modern versions of HMDI have improved the speed of connections. Presently there are five different types of HMDI cables or specification. Each type offers a distinct benefit to the users. HMDI 1.4 is currently in vogue these days.
Benefits of using HMDI cables
HMDI is known for its high definition and superior picture quality. It is also known for its ability for deep colour representations. At the same time, it also supports different audio types, such as stereo and surround sound.
With HMDI cables, you can get rid of the unnecessary clutter of wires and cables. All the above mentioned features and benefits have worked hugely in the favour of HMDI cables.
High Definition Multimedia Interface (HDMI) is an interface provided by cables which allows for the high speed transmission of audiovisual signals. Sometimes you may need to connect devices at a distance from the source of the digital data.
An HDMI cable transmits data at speeds in excess of 10.2 gigabytes per second, without converting it to analog. HDMI retains the original digital nature of the signal producing crystal clear picture and sound quality.
An HDMI cable can accommodate up to 8 audio channels at one time. Here we have discussed the troubleshooting of problems encountered in using long HDMI cables.
Long HDMI cables – Diagnose and repair
An HDMI cable may not be so effective at distances beyond 50 feet. You may find HD cables in the market which are optimised for proper transmission even beyond 50 to 100 feet. However, in these cases you will most certainly require a signal booster and an equalizer. The equalizer enhances the signal quality and the booster pushes the enhanced signal across the distance.
The first effective step to knowing whether it works or not, is to simply try it out. In most cases a long HDMI cable will work well but the performance cannot be guaranteed. The booster will be needed for better performance. Even if you buy two different cables with the same specifications from one manufacturer you may find differences in performance. Some believe to have a long HDMI cable working well for you is a matter of luck.
In most cases the screen will not display any images. Try transmission with an equalizer and a booster assembly for proper diagnosis of the problem. Buy from a retailer who will allow an exchange in case the cable does not work well.
HDMI is the acronym for High Definition Multimedia Interface. It is provided by cables which have the capacity to retain the digital quality of signals and transmit them without converting them to analogue. HDMI cables are available at various price levels depending on their quality and specifications.
Here we have discussed how to get the best results using cheap HDMI cables.
What do you need to do to get a great picture and sound?
You must have 1080p support on your flat panel television. Needless to say, that your electronic entertainment devices must have HDMI support to be able to enjoy HD quality. Explore as many options as you can with retailers before you make you choice.
Copper or silver HDMI cables are cheaper than gold standard HDMI cables as gold is a better conductor of electricity. HDMI offers the fastest transmission of digital data, and speed of conduction is extremely important.
You must remember that the cheapest HDMI cable may not necessarily suit your purpose. Buy a suitable option which gives you good value for money but also the quality level you are looking for. There is no point buying a cheap HDMI cable which does not give you the quality you are after. Strike a balance between low pricing, good brand name and high quality.
