With all the different types of connection methods available today, it’s hard to tell which ones will work best for your setup. It seems that every few years a newer, better standard is released to the public. Since cables are mainly a generic connection method, no specific manufacture advertises their features, benefits, and why the average consumer would need it. Effectively, this can make it hard to know what you need and what you don’t.
Let’s start with the basics. HDMI stands for High-Definition Multimedia Interface. It was designed around December 2002, but hasn’t really caught on with consumers until after 2004. Since it was developed, different versions of HDMI interface have been released. As of writing this article, the latest version used widely today is 1.3. You can think of an HDMI cable as a combination of a DVI (Digital Video Interface) and optical audio.
In the past, I enjoyed using the standard coax connection. Mainly because it included both audio and video in one simple screw-on connection. This made it simple to connect your entertainment system and reduced the amount of cables needed. HDMI also offers this connection method of combining both digital audio and video. This is a definite advantage over other high definition connection methods.
Another benefit that the MPAA (Motion Picture Association of America) enjoys about the HDMI interface is the ability to display copywrited material, also called DRM (digital rights management). When you purchase a new HD-DVD or BlueRay movie, most likely it is copyrighted to prevent unauthorized reproduction. Without the use of HDMI cables, copywrited material may not show properly or in full resolution on your HDTV. This allows the MPAA to release material in full confidence that it will not be reproduced without their consent. As with any type of copy protection, DRM can cause issues by not using HDMI connection methods or if you want to share media on a network.
I’ve also been asked which type of HDMI cable to buy. After you’ve decided on the length, should you get a brand name or generic cable? The answer lies in the fact that HDMI is a pure digital connection, meaning that it is either 100% working, or it is not. Unlike older analog connections like s-video and composite where quality does matter, HDMI cables just need to work. There is not a better picture with a brand name product. One reason why you may want to consider a brand name product is the plastic molding, especially at the stress points in a cable. Most people don’t need to worry about this factor making it possible to save a lot of money by purchasing generic cables.
Nearly any high definition device can offer HDMI options which make this a viable alternative then older component, s-video, or composite cabling. Today, most retail stores offering high definition equipment will support the latest HDMI standards. DVD players, TVs, projectors, and other media equipment can use HDMI to connect to other devices. With all the benefits that HDMI offers, I encourage consumers to look for this connection method to save time, money, and reduce cable clutter.
