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.

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 for the properties of the signal source (eg DVD player) and the display device (eg, hang 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.
