HDMI, DVI and Component Cables Explained

HDMI, DVI and Component Cables Explained

Background:

As the HDTV market continues to heat up, consumers are in need of being educated on the latest technology in order to make intelligent purchasing decisions. There are a plethora of articles explaining the technical pros and cons of the 3 dominant HDTV display technologies namely: LCD, Plasma, and DLP. However, one all- important, but overlooked feature in selecting a HDTV set is the type of HD video connection. The video connections available for HDTV are: component video, DVI (digital video interface) and HDMI (high definition multi-media interface). We will discuss briefly the pros and cons of each.

Component video cable commonly referred to as R, G, B (Red, Green, Blue) actually consists of 3 separate cables because it distributes the 3 primary color components to the display. All colors can be generated from weighted distribution of each Red, Green and Blue color components. Of the 3 HD connection technologies available today, analog component video is the most mature technology.

-Advantage: Analog component video cable is mature and cost effective.

-Disadvantage: component video cables are analog! All HDTV sets are inherently digital therefore extra digital to analog and analog to digital conversion is necessary in order to process the video. This extra conversion can introduce video artifacts. Since all HDTV's are digital, it only makes sense to use an all- digital connection such as DVI or HDMI.

DVI (digital video interface)as the name suggests is an all-digital video connection. Unlike analog component cables the DVI interface transports the original digitized R,G, B video signals from the HD source to the HD display. Since it is all digital, no artifacts or degradation will be incurred. You will get EXACTLY the picture that the video source supplies with no degradation. DVI connection is often found on HDTV as well as PC video cards.

-Advantage : DVI is ALL-digital, so there is no picture degradation from source to display.

-Disadvantage : Digitizing R, G, B requires extremely high bandwidth. The aggregate data rate of the digital R, G, B signals is 1.65 Gbps! The high bandwidth means that cable quality is important and also the link distance is limited. Typical link budget for a DVI is ~ 15 ft.

HDMI (high definition multi-media interface) is the latest state of art audio and video connection. Technically, HDMI is identical to DVI with 3 notable differences. 1) HDMI is a much smaller connector (it looks like an U.S.B. connector), 2) HDMI utilizes copy protection called HDCP (high definition copy protection) and 3) HDMI carries multi channel digital audio. HDMI, like DVI, is ALL-digital therefore picture quality is "perfect" from source to display.

-Advantage: HDMI is a single digital video and Audio connection. Only 1 single cable is needed to transport both audio and video! This significantly reduces cable clutter behind your theater setup.

-Disadvantage: Like DVI, the link distance is limited and a high quality cable is required because of the inherently high bandwidth required to transport digital R, G, B. video.

Conclusion:

As the HDTV market continues to mature, consumers will need to be educated on the HDTV video connections available. We have outlined briefly the main features along with the pros and cons of each connection solution, so the consumer can make intelligent a choice in selecting the HDTV video connections.

What's the Difference Between HDMI Cables, Component Cables and RCA Cables?

What's the Difference Between HDMI Cables, Component Cables and RCA Cables?

A look back at changes in technology over the past ten years is difficult to integrate some new technologies with old. Even if a new TV that does not mean that everything that has bought into it, as well as being updated. However, the wires that must go into your components such as HDMI cables, component cables and RCA cables some fixes and updates.

HDMI cables are an improvement of the quality of the transport of audio andvideos. HDMI cables transmit digital images and sound requires the speed of light, do not pass the video or the audio goes through. Because of the way, HDMI cables to maintain the integrity of audio and video, are consistent for connecting DVD players, cable or satellite and music input via a single cable, which is also interchangeable with different types of converters and adapters used. HDMI cables are the best choice for the lead wire configuration to a minimum andthe best from it.

But keep in mind that all the HDMI cable does not mean it will be HD. Thus, the image and the sound of the BlueRay player is not just the same as your 1984 videos from him. The number of HDMI plug-in can be limited on the TV would mean that you can select the devices for the priority.

Component cables are essentially video cables, which are divided into three components. If you are lookingto life, that in 1984 the old movies, as this may be to help to revive these memories again, without having to block and long o. 'Component cable' The name is the fact that the signals are separated to avoid interference with the other derivatives. Most of the components are separated by a video cable and audio broadcasts. The video broadcasts are also other, sometimes separated into color broadcasting, S-Video, RGB and includeYPbPr.

Component cables can run anywhere from a half-foot to 50 feet in length. They are easy to connect, because most TVs have a color matching plug-in at various points on the TV. This means that if you need a rapid deployment of components plug-in cable (such as a camera) are easy to find and offer a quick way to what you want on the big screen.

The most popular type of component cables are RCA cables, which is always composed of a male nameFinish, color and a copper ring around the entrance, which offers flexibility and Stability. Unlike an HDMI cable is the standard for HDMI irrelevant to the quality that comes out. However, the quality of the cables is important. Consider the design of the line and how they are used. If you do not want on such thin RCA cables in the attic, which is upwards of 140 degrees in the summer months, you roll up to 10 meters behind your RCA cables to sendEntertainment center.

When building your home entertainment center, you should be the priority of your audio and video and TV functions, then measure the length, thickness and quality of the cable needs prioritized, and get the most out of your home entertainment center have, as you can imagine.

HDMI or Component: Which is best?

You have just purchased a new HDTV, complete with HDMI connector and I'm happy
He had the foresight of a DVD player with HDMI interface a while ago to buy
You could not use HDMI even if at that time.

So you can ignore the component outputs and inputs and an HDMI cable
between the two favorite pieces home theater set. After all, HDMI, and all
digital, is bound to be better than component, is not it?

Hdmi

Well, no, actually. Not necessarily. E 'true that a DVD signal convering analog
Send via component video and power cycle the digital TV
lead to a slight deterioration of image quality. And it is true that HDMI removes this
Output. However, the deterioration of the signal component of almost
imperceptable and HDMI do not imagine a little 'problems.

First, even if the DVD video "up-conversion" from a native 420p resolution
Resolution of HDTV (720por 1080i), the signal is still considered a "new timed" in the
Television before being displayed. Some experts suggest that these re-clocking
represents more than artifacts of the process of digital-analog-digital
Conversion. And I make the quality of the processor in the DVD player, the "up-
conversion "is important, if not height, which could adversely affect
The impact on image quality.

Secondly, all devices with HDMI (or DVI for that matter) connectionsmust
Support anti-piracy measure as HDCP (High Bandwidth Digital Content known
Protection). This takes the form of a code that is embedded in digital video
When his signal sent by a reader of content, such as a DVD player and must be de-
HDTV or HD projector encoded. This increases the pressure on the TV screen
Processor without any benefit to the quality of the images, and so could potentially cause
slight loss in image quality.

With componentVideo connectors means that no anti-piracy protection
necessary.

Assuming that does not mean anything to avoid HDMI. Unfortunately this means that
should not assume that HDMI will be better than component. The
only way to find out what is best for your device, try both to see and what
They prefer.

What is HDMI - HDMI is the best reason to 3 RCA Component, DVI and video cables of other

HDMI is a term that you encounter when you buy a TV or a media player.

But what is HDMI? How is it different from other standards available? What does it mean for you? Let's go for it. HDMI (High Definition Multimedia Interface) is a licensed audio / connector interface for transmitting uncompressed video, encrypted digital streams. Hiitachi companies in consumer electronics, Matsushita, Philips, Silicon Image, Sony, Thomson and Toshiba was founded and first published this standardVersion 9 December 2002. This standard uses a single cable to carry uncompressed digital HD video, to carry multichannel audio and some control signals. HDMI uses a single 15 mm, 9 pin cable video and audio signals and a single tool to manage all devices in the home theater system to bear. HDMI devices have the intelligence Ginko? This helps devices recognize TV resolution and auto adjust, so you do not have to worry about the choice of format.

Hdmi

HDMI is a more robustThe form of DVI. It was largely designed to replace DVI and become the de facto standard for manufacturers of consumer electronics. Uses HDCP (High-bandwidth Digital Content Protection) protocol, which protects the output against piracy and provides a secure connection between the source and sink. HDCP helped wide acceptance as an HDMI cable and satellite broadcasting associations have HDCP compliance mandatory in order to prevent piracy. Although the latest version of HDMI is backwards from previous versionscompatible with previous versions, as well as with DVI devices.

Since the first version of HDMI in 2002, new features have been included in any of the versions. Even if all their video resolution 1080pi, they differ in their audio capabilities. Version 1.0 can decode most versions of DVD-audio and digital TV signals such as Dolby Digital and DTS mentioned. Version 1.1 added support for DVD audio, allows users with compatible disks and players with 5.1 channel is listening toThe audio streams without the need for six separate audio RCA cables. 1.2/1.2a versions is free Super Audio CD (SACD) support, the need to leave iLink or analog cables to listen to SACD. The standard also adds support for the Type A connector on the PC.

The last 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. It helps to sustain a higher bandwidth of 10.2 Gbps in the future needs of HD display devices. WithSupport for 30-bit color depth, 36-bit and 48 bit, can bring the devices can represent any color in nature, with such details as the human eye. Significantly removes on-screen color banding, for smooth tonal transitions and subtle gradations between 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 as wellBridging the gap between consumer electronics and the PC world. Simple wiring, crystal-clear audio / video, HDCP compliance and interoperability with PCs have HDMI set in the forefront of connectivity standard and made it the de facto standard.

What is the difference between HDMI and component cable

A real game is the print quality that will result in the sense of theater at home. The confusion comes when you must make a choice between HDMI and component cables. Both are known to be used for home entertainment systems.

HDMI stands for High Definition Multimedia Interface. These cables are suitable for transmission of audio and video signals at the same time does not cause similar Scart could manage. They should provide unbreakable signalConnectivity with longevity. If cloak of gold, would improve its performance. It will help in any format of video signal to your TV or PC. They are compatible with almost any home entertainment systems, and then virtually connected to each other as they come. The cost varies depending on the variety.

Hdmi

The format in which the component cable is based on an analog format. Therefore they are not compatible with the HDMI cable. The component cables are signs of tensionforming a wave pattern on the basis of the analog signal, changes in height is a significant factor. This component connections are very undervalued, even if they are able to provide better image quality, as good as HDMI cable. The longer component cables are promising, 25 meters or more.

Both component and HDMI cables are good at what he meant, because that is going to be to the owner of the home entertainment system. But if you want to have a single cable,work then go with the HDMI cable.

What is the difference between HDMI and Component Cable?

A bit short, do not wire to make a difference. What's different is that in the case of a component cable, TV, converts the analog signal into digital needs of constituents. In the case of the HDMI cable, the signal is already digital. Can be a significant difference if the TV does not make the transition well.

Apart from image quality, is the reason why you must use the HDMI cable that carries the signals HDCP, not component. When the sound source, such as aCable Box, locate the HDCP handshake, and do not get out will not be an HD signal. In fact, if you see on HBO in HD from a cable box, you must use HDMI or DVI.

Hdmi

I use a component cable. Then again, I had about $ 60 on it (gold plated finishes, great conductors, thick shielding, etc.) for both component video and audio channels. And, I bought a few years before the HDMI cables were also around. The difference in performance between high-end video component cableand the HDMI cable is negligent. But if only the standard RCA cables - as proposed by the company cheap cable TV for you - you will not be as good as the HDMI cable.

As HDMI cable connections becoming increasingly common, there are often asked: what is better, HDMI or component video? The answer, as it happens, it will not cut and dried.

First, a note: everything is said here seems to DVI-HDMI and DVI devices to consumer electronics less and less of allof time, not so often asked, but DVI and HDMI are essentially the same as any other, the image quality-wise. The main differences are that HDMI carries audio and video, and uses a different type of connector, but both use the same encoding scheme, and that's why a DVI source can be connected to an HDMI monitor, or vice versa, with a DVI / HDMI converter without intervening.

The conclusion of this article - if you are not inclined to read all the details - iswhich is very difficult to predict whether an HDMI port is the image better or worse than an analog component video for connection. There is often considerable differences between analog and digital signals, but these differences are not part of the connection type and instead on the properties of the signal source (eg DVD player) and the display device (such as hanging your TV). Why that is, but it requires a bit 'more debate.

Several peopleDay for a solution to the interconnection of research trying to HDMI to Component outputs via a cable connection for high-definition equipment. Unfortunately this is not a matter of reorganization and the right wires to the terminal. There is a fundamental analog versus digital incompatibility problem similar to the current transition to digital TV broadcasts coming in comparison to your rabbit ears to receive analog signals. They are not compatible and can only confuse peoplelike the poor guy in the commercial register.

Component video is analog format. With analog signals, the voltage signal on the wire as a change in wave format and aired on the level of what is important. It 'an infinite number of values ​​between zero and maximum, as something variable wipers had on an old Thunderbird. With the HDMI or DVI format, are based on digital signals. Digital than you have probably heard, using ones and zeroswith a series of pulses all at the same height and are present or absent. At the other end, the plants re-processing of the information along. In a 4-bit binary encoding, it is possible one of 16 different values ​​of 0 and 4 1 friends have put together a group of 16 different combinations. So equipment at the other end of the cable, the detection signal and is in search of analog sine waves would be erased completely without meaning, if it has only received pulses of 1 and 0

Some solutions are verysimple. When an HDMI or DVI output is available on both boxes, use them. The difference between DVI and HDMI is that HDMI audio caries in addition to video signals. But DVI is only as good and others that the cost of an additional audio cable to solve your problem. If you try to use the component outputs, as already tied the HDMI connection, HDMI Switch boxes are rather cheap if you have multiple HDMI cables are on one side to an output connectorother.

Component video cable, an analog signal is transmitted. HDMI is digital. Among other things, this has the following advantage: as long as the data is correct, we have the perfect image transfer incoming data to the TV. Not a single pixel difference in the device that eliminates the "send" and it reaches your TV. Component signals (such as all analog signals), quality, and problems may occur.

So, in effect: At first glance, may seem HDMI cablemost expensive component cables, but it is not right. Requiered for the quality of the HDMI cable is the length you need. If you are only a short distance (two or three meters) for a cheap cable gives you the best possible outcome to meet ever reached by any means ... Digital is ... the cheap cable does not affect the image quality ... how to use the network cable from your computer to connect to inet has no effect on image qualityVideo, you download the stream.

This does not mean the component is evil in good analog video connections is probably by far the best, but only HDMI has the advantage of not having to worry about inadvertently signal "affected" by external influences during the transfer. So if you: HDMI is the best choice.
