What is the difference between HDMI and component video?
Answers: Hi. HDMI is a digital Video and Audio Connection. Component Video is a purely analogue video nouns. Quality wise near is no difference between the two connections
EDIT....Digital does not always make out better image level in the grip of a video connection.There are significant differences within the way digital and analogue signals are handle that are heavily dependant upon the characteristics of the Source device and the Display rather than the type of video nouns in use.
HDMI - digital cable format that transmits up to 1080p video and 8.1 surround nouns audio.
Component - analog cable format that transmits up to 1080i video and no audio.
It's difficult to tell the difference contained by quality. If you look closely, HDMI will be the better choice because it is digital.
Others are right re. relative element. But one caveat ... component is actually better at long distances than HDMI. And here is an important supplementary wrinkle consumers need to be cognizant of: HDCP (High-bandwidth digital copy protection, See relationship 1).
It isn't fully active nonetheless but once it is you won't get more than 540p (and usually 480p) out of an analog nouns and with HDMI if both devices (e.g. HDTV, HD DVD or Blu-ray player, A/V receiver) connected are not HDCP compliant, you will draw from nothing (no signal). So, contained by essence HDMI will be the only channel to get HD ... which is why it is influential to buy HDCP compliant devices now and expect to enjoy to connect them with HDMI at some adjectives date (probably 2-3 years).
BTW, HDMI cables do not -- for most uses -- entail to be top quality. $10 cable from Monoprice.com will perform identically to Monster ($100-$200) at distances underneath 6' and at resolutions up to 1080p (See link 2)
In standard you want to go beside HDMI.
The cable is cheaper, carries audio & video contained by 1 cable.
Another issue: televisions hold to convert analog signals from component cables into digital for internal processing. This is much simpler if you nurture digital signals to a TV with a HDMI cable than next to component cables.
Some populace will say in attendance is no difference in video part, but on a 42 inch or larger set that is 1080p near is definitely a difference. Add to that the reality that component video is analog and is susceptible to signal interference from RF and electrical sources while HDMI is not as it is a pure digital signal. The other difference is that HDMI also carries audio and except using 3 or 4 pairs of analog audio cables for multi-channel output, the up to date audio formats used by HD DVD and Blu-Ray such as Dolby TrueHD and DTS Master HD as well as PCM Uncompressed nouns the 6-8 analog cables or HDMI are the simply ways to get those formats as they will not work over optical or coax connections.
My heir does not have HDMI connectivity so I use 6 analog cable to enjoy DolbyTrueHD and Uncompressed nouns from HD DVD and Blu-Ray while the HDMI runs straight to my plasma tv.
