Many people search for an adapter to connect HDMI cables to Component Outputs for their HD video signal. This isn’t an issue of just rearranging wires and having the correct type of connectors though. There is a basic analog versus digital incompatibility issue, like the upcoming digital broadcast TV switchover versus current TV rabbit ears that get analog broadcast signals from broadcasters. Digital and analog signals are completely different. Component video is founded on an analog format. For analog signals, the voltage signal within the wire is in a wave style, and how the wave moves in its height is what is most critical. Theoretically there are an infinite number of intermittent values for the magnitude of the wave height between 0 and the maximum amplitude. Both HDMI and DVI formats, however, are principled on digital signals. As you may have heard, digital uses a series of pulses of ones and zeros, which may be either present or missing in the series. The information is reassembled by the processing equipment at the other end. When working with binary 4-bit code, there is a possibility of 16 unique 4-digit numbers. So equipment from the other side of the cable that is detecting signals and looking for analog sine waves will only see complete garbage if it has just received pulses of ones and zeros. So, what options are available? There are some simple ways to handle it analog vs. digital issues. If both of the boxes have an HDMI or DVI output available, they should be used. DVI and HDMI differ in the fact that HDMI carries the audio and video signals in one cable whereas DVI does not. DVI's video quality is equivalent to HDMI; it just requires the use of an additional audio cable. If you wanted to use the Component outputs because you had the HDMI port tied up, there are HDMI switch boxes that are quite cheap where you can plug multiple HDMI cables in on one side with one output on the other side. Slow down if you're considering converting from Component to HDMI just because someone told you that HDMI is better. HDMI cables and other digital solutions might be superior in theory because there are so many potential conversions between different lines of resolution and formats from the origination of the signal until it finally is displayed on your TV. But several studies show that Component connections end up delivering a better signal and picture. This is often the case with cables greater than 25 feet long. If it is feasible, test out both kinds of cables and determine which one offers you the highest quality video picture. If you have no other option and you absolutely have to do a conversion from Component to HDMI cable, you can get a converter box, but it will generally be priced at more than $200. If you decide to go from HDMI to component cables, HDCP access may be denied to you due to High Definition Content Protection restrictions. With any luck your HDMI to component situation is a simple one that can be fixed with one of the aforementioned HDMI to Component solutions. If none of this works, you have the perfect excuse to go buy new equipment.
