Time for a move to HDMI?
With the proliferation of the audio and video devices that we all seem to collect these days we’ve all ended up with a jungle of cables connecting it all together.
In some ways that wouldn’t be so bad as it’s usually all hidden at the back of the TV or stereo but the problem is that in many cases there are conversions to/from analog and digital between the various devices. Each of those conversions results in a loss of quality and should be avoided when possible. In the old days it wouldn’t have been so bad as we’d have maybe had the aerial going into the back of the video then to the TV but these days you can have chains of devices converting between analog and digital eg aerial to video to DVD to stereo to TV and that gives quite a noticeable drop in quality.
The way out of this is to use HDMIÂ (High-Definition Multimedia Interface) which is a cabling technology supported by the latest devices and which lets digital signals stay digital thus you don’t get the drop in quality that you may be experiencing at the moment. Chances are that not all your current gadgets will support this but it’s something that you should be looking out for on new devices as you’ll really notice the drop in signal quality as you upgrade to the likes of large flat screen technology and HD TV.
