With HDTVs gaining popularity every year, HDMI cable is becoming more prevalent as well. HDMI, short for High Definition Multimedia Interface, is the latest cable connection that is used with HDTV sets and computer monitors, cable boxes, and DVD players. This technology is meant to simplify the cords running between your TV and peripheral devices. Here is a closer look at this connector.

To begin, let's discuss the makeup of HDMI. Basically, there are 19 separate conducting wires. These consist of five main twisted pairs, each with a drain wire, as well as four other individually insulated wires. The majority of these are able to perform a variety of tasks and send significant quantities of data. Therefore, the quality of these wires, exactness of the construction, and the excellence of the end point all affect the cable's ability to perform correctly. These cables are described by their capacity, namely speed, not by their features. There is one exception to this, the Ethernet cable. Other than this, HDMI isn't affected by resolution, color depth, or refresh rate of the signal.

Ethernet compatibility was introduced with the unveiling of version 1.4. Using an Ethernet cable, you can connect your HDTV directly to the internet without an interim device. This allows users to take complete advantage of their IP-enabled machines without the annoyance of an extra cord or connecting device. The configuration uses an extra pair of wires for the Ethernet signal to pass through. As a result, this cable is available in either a high or standard speed option.

With HDMI, both audio and video digital signals are transported through the same cable. You're probably familiar with the older RCA cables in which three connectors plug into color-coordinated slots in the back of your TV. HDMI offers support for both standard and high-definition video, as well as compatibility with DVI-I and DVI-D cables. This allows the older tri-connector cable to be replaced by a single plug-in. Also a part of this newer technology is the addition of ferrites. Ferrites work to provide a clean picture by decreasing video noise and also minimizing electrical noise output.

Compatibility issues may arise when using HDMI with varying ports and connections. DVI-D supports HDMI displays; however, if the HDMI needs HDCP for all signals, then the DVI cable must also support HDCP for output. The same is true when connecting a cable box, DVD player or Blu-ray player to a DVI-D monitor port. Whenever HDCP is seen in the signal's origin, the display should also support this cable.

As for the actual cables, the unique copper construction lends itself to longer transmission with cables up to 100 feet. When joined with a repeater, cords can be connected to provide even longer lengths. HDMI cables come in a variety of styles, including a flat cable, Type A, and Type C, also called the mini-HDMI. The flat option is excellent for installing underneath carpet, furniture, or running against a wall. The flat shape reduces the profile of the cable, decreasing the potential for damage. Type A is the current standard format for HDMI. It uses a 19-pin configuration for transferring digital signals. Type A works with all formats up to 1080p, which is currently the highest broadcast standard. Finally, Type C, or mini-HDMI, is often used with video recorders and other portable video devices. As the name suggests, this cord is quite a bit smaller than typical connectors.

As you can see, HDMI cables are the most advanced connection available today. The picture quality, soundFree Articles, and ease of use are all worth the extra cost. Check them out for yourself today!
