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.

Component to HDMI

Every day, consumers are looking for their network problems with trying to HDMI to Component outputs connected via a cable to connect to their HD fix installation. This is not simply a matter of reorganizing cable or unfortunately, with the right kind of plug. Essentially incompatible analog and digital, as the fast-approaching transition to digital television broadcasts from analog signals can be received by rabbit ears or a roof antenna. Why notcompatible amazed at the wind, people like the unfortunate person who sees in advertising.

Analog and digital signals are very different. Note that a similar component video signal is formatted. The voltage signal on the cable broadcast in a format to an analog signal, and the variations in wave height is the key. In theory, an analog signal is found values ​​between zero and infinity, as the windshield wipers on an old ThunderbirdVehicle.

In HDMI and DVI, but this is recorded in digital form. As you may already know, digital ones and zeros and a series of pulses at the same height, and are either there or not. The information is put together device processing at the other end. So any device that is expected from a wave analogue cable is the only ones and zeros interpreted as noise.

What alternatives are there for? HDMI or DVI output can be used if it is on bothBoxes. The only difference between DVI and HDMI is that HDMI carries video signals in addition to audio signals. DVI on the other hand, is just as good, but carries video and audio on separate lines in order to bear the cost of an additional audio cable. It makes a fairly inexpensive HDMI switch that has multiple HDMI cables if you tried to use the component outputs, because the HDMI port was already bound can attack.

When you hear that HDMI is superior toComponent cable, and want to convert HDMI Component would be to take a moment. There are numerous studies showing that HDMI cables are superior to the theory and digital format. This is because there is a lot of potential conversions between the various lines of resolution, before finally being displayed on your TV. For this reason, there are opportunities to predict the component connections, a better signal and picture. Above all, this is the case when starting the cable lengthover 25 meters. To determine the cable, which offers you the best looking image, each of the cables, if given the chance.

If you need to convert from Component to HDMI converter boxes are available but usually cost more than $ 200. However, if you go in the opposite direction, you can run into limitations when it comes to high definition content protection. This will prevent the possibility of view HDCP protected sources.

We hope that it is easy to solve with HDMIProblem with component HDMI or component cable solutions listed above. Otherwise, it gives you a chance to go in a large high-tech shopping spree.

What is the difference between HDMI cables, component cable and RCA cable?

A look back at the changes in technology over the past decade is difficult to accept some of the new technologies with the old. Even if a new TV that does not mean that everything that has bought into it, is also updated. However, the cables should go to the components as the HDMI cable, component cable and RCA cable or update some settings.

HDMI cables are one of the improvements in sound quality and transportation wereVideo. HDMI cables transmit digital picture and sound at the speed of light, which does not require conversion to video or audio to come 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 used interchangeably with different types of converters and adapters. HDMI cables are the best choice for the leadership of the wire configuration to a minimum andmost out of it.

However, remember that what is put in the HDMI cable does not mean that it keep its HD. So the image and the sound of BlueRay is not the same player to watch your movies through 1984. The average number of plug-in HDMI limited to, what would you possibly choose which devices have priority.

Component cables are essentially video cables, which are divided into three components. If you are looking forto life, that old home video in 1984, as this may be what you need help refresh the memories without worrying about the pixel and / or stretched. Cable Component name 'is "the fact that the signals are separated from each other, resulting to avoid interference with each other. Most of the component cables for video and audio transmission division. The videos are broadcast more often in those based transmission, S-Video, RGB and are separatedYPbPr.

Component cables can run anywhere from half a foot to 50 feet in length. I'm just too much, because most TV's have colorful plug-ins in multiple locations of the TV plug. This means that if you need a rapid deployment of component-cable plug-in (like a camera) are easily accessible and offer a quick way to get what you want on the big screen.

The most popular type of component cables RCA cable, consisting of a male nameFine, that is color and has a copper ring around the input features, flexibility and stability. In contrast with HDMI cable, the gauge of HDMI cable is irrelevant to the quality that comes out. However, the quality of the cables is important. Consider the technology of the spinal cord and how they are used. Not so subtle RCA cables in the attic which is over 140 degrees in summer you're going to send up reel 10 meters behind the RCAEntertainment Center.

During the construction of your entertainment center, consider the priority of audio and video devices and the functionality of your TV, then measure thickness, length and quality of your cable needs prioritized, and there will be more out of your center home entertainment as you get could imagine.
