What is the difference between component and HDMI cables?
![Hdmi]()
On a short length, not the cable makes no difference. What is different is that in the case of component cables to convert the TV signal to analog component to digital. In the case of HDMI cable, the signal is already digital. So it could be a big difference if your TV does not convert well.
Image quality aside, the reason why we recommend using the HDMI cable carries the signals is that HDCP is not component. If the source device, such as aCable box, looking for the HDCP handshake, and do not get it, it will output an HD signal. So if you want to watch HBO in HD from a cable box, you must use HDMI or DVI.
I use component cables. Then again, I was above $ 60 on it (gold plated, great conductors, often shielding, etc.) for both component video and audio channels. And, I bought a few years earlier were still in the HDMI cable. The difference in performance between the top-end component video cableand an HDMI cable is negligent. But if only standard RCA cables - as the company offers cheap cable TV for you - are not as good as the HDMI cable.
How the HDMI cable connections spread more and more, we 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, as it appears for DVI-HDMI, DVI for consumer electronics devices less and less of alltime, not so often asked, but DVI and HDMI are essentially the same story, the image quality-wise. The main differences are that HDMI carries audio and video, and uses a different type of connector, but both have the same encoding scheme, which is why a source to a DVI to HDMI monitor, or can be connected and vice versa, with a cable DVI / HDMI cable, with no intervening converter.
The conclusion of this article - if you are not inclined to read all the details - iswhich is very difficult to predict whether an HDMI connection is better or worse image of an analog component video to connect. It will often be significant differences between digital and analog signals, but the differences are not part of the connection type and instead depend on the characteristics of the source (eg DVD player) and the display device (such as the TV). Why this is so, however, takes the discussion a little 'more.
Several peopleDay looking for a solution trying to HDMI interconnect to the outputs of the component via a connection cable for their high-definition equipment. Unfortunately, this is not a matter of reorganizing the right kind of cables and plugs. It 'a problem of incompatibility of basic analog and digital transmission similar to the upcoming digital TV to receive over the passage of rabbit ears for your current analog broadcasting 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 signal voltage on the cable in wave format and how changes in wave height, what is important. Theoretically, there is an infinite number of values between zero and maximum, variable wipers I had something like on an old Thunderbird. With HDMI or DVI format, these are based on digital signaling. Digitally as you have probably heard, uses ones and zeroswith a series of pulses all at the same height, and are present or absent. At the other end of the new set of information processing systems. Mounted on a 4-bit binary encoding can be one of 16 different values of 4 1 and 0 as the group can have 16 different combinations. Equipment only at the end of the cable, the signal acquisition and is looking for analog waveforms would put out a total nonsense when he received pulses of 1 and 0
Some solutions are verysimple. When an HDMI or DVI on both boxes, use them. The difference between DVI and HDMI is that HDMI caries in addition to audio and video signals. But DVI is just as good and other than the cost of an additional audio cable, that will solve the problem. If you try to use the component outputs, because it is already linked to the HDMI connection, HDMI switch box that they are fairly cheap, where there are multiple HDMI cables on one side with a pin can outputother.
Components via a power analog signal is transmitted. HDMI is digital. Among other things, this has the following advantages: As long as the data is successfully transferred the perfect image of the incoming data into your TV. It is not a single pixel in the difference that erases the device 'submit' and what the TV will be reached. Component signals (such as all analog signals) may be of varying quality, and you can get interference.
So basically: At first glance, might seem the HDMI cablemore expensive than component cables, but it is not right. For the quality of the HDMI cable is requiered to the length you need together. If you have only a short distance (two or three meters) to cover a cheap cable offers the best possible result that can be achieved by any means ... is digital ... the cheap cable does not affect the image quality ... exactly as you use the Ethernet cable from your computer to connect to inet has no influence on image qualityVideo download / stream.
Of course this does not mean bad part: In favor of analog video connections is probably by far the best, but only HDMI has the advantage of not having to worry about the signal accidentally "touched" by external influences during the transfer. So if you can: HDMI is the best choice.
