Are there any video diferences beetween HDMI and Component ?
As DVI and HDMI connections become more and more widely used, we are often asked: which is better, DVI (or HDMI) or component video? The answer, as it happens, is not cut-and-dried. First, to clear away one element that can be confusing: DVI and HDMI are exactly the same as one another, image-quality-wise. The principal differences are that HDMI carries audio as well as 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 cable, with no intervening converter box. The upshot of this article–in case you’re not inclined to read all the details–is that it’s very hard to predict whether a digital DVI or HDMI connection will produce a better or worse image than an analog component video connection. There will often be significant differences between the digital and the analog signals, but those differences are not inherent in the connection type and instead depen
I’ll give you two answers here. First, regarding the quality of HDMI vs. component, there’s no question that HDMI delivers a cleaner and sharper picture than component. I just bought my parents and HDTV and their old DVD player only has component out, not HDMI. When I set it up and watched a movie it was very clear to me that the picture wasn’t as good and there was a little bit of noise visible that isn’t visible on my TV, which uses HDMI. So if you’ve got the option, always use HDMI if you can because you will get a better picture. And yes, HDMI will also deliver audio so you’ll use fewer cables. Also, it’s possible that future Blu-Ray releases may not output a full 1080p image if you don’t use HDMI for copy protection reasons. So that’s another important difference. As to your PS3 problem, try this solution to see if you can get HDMI working: Hook up your ps3 with the component cables thru the multi link. Also go ahead and hook the hdmi to ps3 and the tv. Go to display on the ps3 an
What are DVI, HDMI and Component Video? The principal important difference is that DVI/HDMI deliver the signal in a digital format, much the same way that a file is delivered from one computer to another along a network, while Component Video is an analog format, delivering the signal not as a bitstream, but as a set of continuously varying voltages representing (albeit indirectly, as we’ll get to in a moment) the red, green and blue components of the signal. Both DVI/HDMI and Component Video deliver signals as discrete red, green, and blue color components, together with sync information which allows the display to determine when a new line, or a new frame, begins. The DVI/HDMI standard delivers these along three data channels in a format called T.M.D.S., which stands for “Transmission Minimized Differential Signaling.” Big words aside, the T.M.D.S. format basically involves a blue channel to which horizontal and vertical sync are added, and separate green and red channels.
