5 of the most common HDMI Q & A

Over the past 12 months, sales of HDTVs have soared. Today's cutting-edge HDTV and high definition sources demand much higher data rates than previous generations of audio / video components. They provide the bandwidth incredible / performance demands on HDMI cables. In fact, most modern components work very close to the limits of current technology HDMI to close.

online forums have been inundated with questions about HDMI cables. As an industrialI have inside information on a number of these problems. Here are five of the most common request.

1. Is there really a difference between expensive and cheap HDMI cable is connected?

There is a difference between expensive and budget HDMI cable. It is about the quality of the cable construction and materials used. The question is whether this in my set up. First you must determine the length between the source and display. If this is less than 15 meters"Standard" cable will do.

If there is more than 15 feet, you're best to consider a "high speed" cable. Make sure you buy from a trusted source and that the cable with the HDMI logo and says there is a marked version 1.3 (not a, b or c, since only the fear testing protocols) If you are in a live - coastal area or high humidity, it is worthwhile to always use a cable with gold plated connectors. Although this will not improve your signal will stop corrosion degrade the signalover time.

Some people assume that the signals are digital cable and it works or not. Sometimes, however, 1 and 0 are all there because the signal loss caused by low construction cable. This may, in particular with audio and video sources such as CD and DVD. The signal degrades gracefully to a point and then break. Music and video is not as data. digital signal processors, a job with noise-free signal and provide less than perfect sound andPictures.

You can never improve a digital signal through a cable expensive, but you can certainly worsen a signal with low quality cable.

2. E 'turn right, the HDMI cable?

It 'best not to bend the HDMI cable, of course, does not bend. This means changing the line spacing, shielding and isolation inside the cable.

The manufacturing process of the cables can have a dramatic impact on how the information looks from one side ofCable to the other. This means that a cable with better shielding and a more precise distance between the 'intelligence "and" ground "wire will make a better connection with less interference. Many things can affect the signal. The electrons generate a standing wave in the cable, which will create a small magnetic field around the cable. Each imperfection or disrupt junction in the cable and reflect these waves / breaking waves. magnetic information can also leak from a cableanother.

3. Do I have HDMI 1.3a, or 1.3b HDMI cable or buy?

It 's a bit of confusion in the market in all versions. What is the specific version referenced here, not the connector type to be confused.
As long as you have version 1.3, is found to be in order. The suffixes a, b or c refer only to test protocols and do not really have on consumers, even if the perpetrators are using to market. (Numbers and letters are largermore ...)

4. Can I get the same quality video / audio cable HDMI DVI-D?

"DVI-I" stands for "DVI-Integrated" and supports both analog and digital broadcasts, so it works with both analog and digital display devices. "DVI-D" stands for "DVI-Digital" and supports digital transfer. DVI also includes provisions for a second data connection for high-resolution displays, though many devices do not implement them. In those that do, the connection is at timesas DVI-DL (dual link).

When you convert HDMI to DVI drops audio as DVI does not support all audio signals. You must take a separate line between the source and the sound system for this work.

You should check the settings of the software in source, so they know you're not the HDMI audio output, but from a single outlet.

Some new DVD players, televisions (including HDTV sets) and video projectors DVI / HDCP connections, whichphysically the same as DVI connectors are provided, but an encrypted signal using the HDCP protocol for copy protection. Computers with DVI video connectors you can use many DVI-equipped HDTV sets as display, but because of digital rights management, it is unclear whether they will eventually be able to play protected content, such as the connection is not encrypted.

5. When I connect my laptop to my HDTV Blu-ray you get an error of violating copyright laws. What can I do?

Before beingHDCP (copy protection for high-definition) problem here.

HDCP is a form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels through various cables and connections, even if they are approved by copying fair use laws. "Each unit will shake hands with others and then pass a key that it's okay to display or reproduce the signal. He does it for every frame, usually 30 times per second.'re withProblems with the audio or video in white, is more than likely that one of the devices do not support HDCP.

The normal way, if you are using the HDMI port are all the way through the chain of connection is not the problem.
