An Overview Of The HDMI Cable

When most people are told they need to get an HDMI cable for their computer, their eyes glaze over and they are at the mercy of the technician or salesman telling them that the only "good" cable is going to cost a gazillion dollars, but that is the only one that will work on their system.

Having a little information about these cables and what they will, or won't do, and whether or not paying more is really going to get you a cable that will beam your system to the moon is going to be very helpful and save you a lot of money.

A HDMI cable is a high definition multi media interface digital platform that was created to allow providers to use HDCP (High definition content protection) effectively. HDCP gives providers the power to limit a consumer's access to programs, video content and copying. It makes the ability to enforce copyrighting easier for providers.

Because it was not created as a convenience for consumers, there are some inherent issues with HDMI cables that have been limiting. It is not robust, reliable over any distance, cannot be easily switched, is not distributed economically, and does not connect securely to devices.

When a salesperson tells you that their cable has a special feature that will allow you to over-ride copyright or video limitations, unless they are including a special gizmo that is unrelated to the cable in the package, the cable alone is not going to be able to do that.

While some cables may have a greater bandwidth, it is not going to be effective if you system and the data you are receiving and sending is not designed to carry that bandwidth. This will be an extra expense that you do not need to make.

The prices of the cables vary greatly, however, it is important when comparing these cables that they are not that different. Testing and research has shown that a more expensive cable does not mean that it can perform better than a more affordable cable.

An HDMI cable is a digital version of an RGB analog video signal and is carried on four shielded twisted pairs the same as a CAT5 cable. The difference is that there is shielding added. The signal strength of the cable begins deteriorating when the cable is too long, approximately 30 feet or ten metres.

The HDMI 1.3 version has an increased bandwidth and has added support of "deep color". Since there are only a few high-definition camcorders that use "deep color" few people will need this addition. In addition, there are no plans for Blu-Ray to begin using "deep color" on their discs.

In addition to the automatic lip syncing feature the cable has one feature that can be a valuable addition for some users. It enables a person to send high resolution sound tracks such as Dolby TrueHD and DTS-HD Master Audio in bit stream format. This eliminates the need to have a compatible player to covert soundtracks to PCM.

While the Consumer Electronics Control (CEC) is mandatory in the cables, they may also have a DDC (Display Data Channel) or a TMDS (Transition minimized differential signaling) channel. The channel capability will be important depending on your primary uses for the cable that you are using.
