What Is HDMI - Why HDMI is Better Than 3 RCA Component, DVI, and Other Video Cables

HDMI is a term you will come across if you buy a TV or a media player.

But, what is HDMI? How is it different from the other available standards? What does it offer you? Let's go for it. HDMI (High Definition Multimedia Interface) is a licensable audio/video connector interface for transmitting uncompressed, encrypted digital streams. Consumer electronics companies Hiitachi, Matsushita, Philips, Silicon Image, Sony, Thomson, and Toshiba founded this standard and released first version on December 9th 2002. This standard uses a single cable to carry uncompressed digital HD video, multi-channel audio and some control signals. HDMI uses a single 15mm, 9pin cable to carry both video and audio signals and a single remote control to operate all the devices in your home theatre. HDMI Devices have Gink intelligence? That helps devices recognize TV resolution and auto adjust it so you don't have to bother about choosing the screen format.

HDMI is an enhanced and robust form of DVI. It is widely replacing DVI and is becoming the de facto standard for the consumer electronics manufacturers. It uses HDCP (High-Bandwidth digital content protection) protocol which protects the output from piracy and provides a secure link between the source and the sink. HDCP helped HDMIi wide adoption as cable and satellite broadcasting associations have made HDCP compliance mandatory to avoid piracy. Though the latest release of HDMI is ahead of previous versions, it is backward compatible with the earlier versions as well as with DVI devices.

Since the first release of HDMI in 2002, new features have been added in each of the versions. Though all of them support 1080pi video resolution, they differ in their audio capabilities. Version 1.0 could decode most versions of audio contained in DVD and digital TV signals, including Dolby, Digital and DTS. Version 1.1 added DVD audio support, which means users with compatible disks and players can listen to 5.1 channel audio streams without the need for six separate audio RCA cables. Version 1.2/1.2a added Super Audio CD (SACD) support getting rid of the need to rely on iLink or analog cables to listen to SACDs. The standard also adds support for Type A PC connector.

The latest Version1.3b/1.3a/1.3b adds support for Dolby TrueHD and DTS-HD Master Audio which are used in Blu-ray and HD DVD players. It supports an increased bandwidth of 10.2Gbps to support the future demands of HD display devices. With support for color depths of 30 bit, 36 bit, and 48bit, the devices can represent any color in the nature with as fine details as a human eye can perceive. It significantly removes on-screen color banding, for smooth tonal transitions and subtle gradations between the colors. It synchronizes video and audio with greater accuracy so you can experience crystal-clear video and audio quality.

HDMI is now enhanced for easier integration with low voltage, AC coupled PC graphics controllers thus bridging the gap between consumer electronics and the PC world. Simple cabling, crystal-clear audio/video, HDCP compliance and interoperability with PCs have put HDMI in the fore-front of connectivity standards and made it the de facto standard.

Why HDMI is the Number One Choice For All Your Home Theatre Connections

Why HDMI is the Number One Choice For All Your Home Theatre Connections

The introduction of high definition TV has truly enhanced the home cinema experience enjoyed by consumers, but it has also caused a lot of confusion and uncertainty. It doesn't help that manufacturers have been focusing their efforts on several different connection types over the past decade, which means that there are now thousands of different devices on the market, all of which use different types of plugs. FireWire, DVI, and HDMI are all connection types that have enjoyed the limelight and have been found on the backs of TVs at one time or another, and now most consumers are totally confused about the differences between these connections and which type is best.

What's The Big Deal About Connections?

Many people don't understand why there is such a big deal about something as simple as a connection, surely it's just a way of plugging the cable into the TV; surely all connections basically do the same thing? The war between different connection types really boils down to money. It costs companies a fortune to develop a new connection platform, therefore they are eager to get as many manufacturers using their connection as possible so that they can charge a royalty. If one connection emerges as the global standard, then it can be incredibly lucrative for the company that owns the royalty rights; hence the fierce competition to try and establish each of the connections mentioned above as the global standard connection for all HD devices.

The Emergence of HDMI

As the technology behind HD TV developed it quickly became apparent that a new connection was needed that not only delivered digital quality signals, but was also easy for consumers to use. The first attempt at a digital connection was FireWire - this used just one cable to deliver audio and video signals, and also allowed devices to communicate with each other. However FireWire never really gained much support from manufacturers and hence soon fell out of fashion without ever reaching its potential.

DVI was next and was originally developed for the PC industry. DVI cables only carried video signals, but they could support both digital and analogue connections. When home entertainment manufacturers saw that DVI had gained favour with PC users they started to incorporate DVI connections into their products. However, the large form factor and lack of audio support meant that it wasn't ideally suited for use in home cinema systems.

HDMI is almost identical to DVI; however it does offer improvements in some important areas. For instance, HDMI cables use a plug with a much smaller form factor, which is important when space behind your home entertainment system is limited. HDMI is also able to carry both audio and video signals in a single cable, meaning that only one cable is needed to make a connection. HDMI cables can also carry a remote control command, which helps to simplify the process of connecting and using several devices together. Perhaps most importantly, HDMI cables are also relatively cheap to produce, and have therefore become a favourite with HD TV and home entertainment manufacturers.

HDMI Is The Sensible Choice

As you can see HDMI cables offer several advantages over the other types of connection, which explains why the vast majority of home entertainment equipment manufactured in the past couple of years almost certainly uses HDMI as the standard type of interface.
