HDMI Cable Specifications

The specifications of HDMI cables are not very well known among the general public. However, they do have some important features. They provide high quality video transmission over long distances (up to 1 kilometer). The cables are able to transmit uncompressed digital audio signals at up to 6.4 megabits per second.

These cables are designed to carry both analog and digital video signals, which means they can handle all types of content from standard definition to high definition.

The HDMI specification was first published in 1999 and it is currently used by many consumer electronics manufacturers including Apple, Dell, HP, Lenovo, Samsung and Sony. The specification defines how the technology works. It specifies the minimum and maximum bandwidths of each channel, as well as the number of channels that can be connected to a television or monitor. The specification does not specify what type of signal must be transmitted; however, most HDMI cables will support HDCP 2.2 (High-bandwidth Digital Content Protection), which allows for encrypted video streaming between devices without any degradation in picture quality.

There are three types of HDMI cables: Standard or High-Speed HDMI Cables, Category 2 and 3 HDMI Cables, and the new HDMI Ethernet and Audio Return Channel (ARC) Cables. All of these are put to use in home theater systems, but they are not all compatible with each other.

Standard or High-Speed HDMI Cables have a single-strand 28 AWG copper core. They also have plastic reinforcement, which protects the internal wiring. This type of cable was the first to be used for HDMI connections and it can support 1080p signals and Dolby TrueHD, DTS-HD Master Audio and up to 32 audio channels. It can also support video resolutions of up to 4k.

Category 2 and 3 HDMI Cables are capable of even higher performance than the standard or high-speed cables. They contain a pure copper core and are the next-generation of HDMI cables. They can be used for 3D, deep color video (x.v.Color, etc.) and multi-channel digital audio.

The new HDMI Ethernet and Audio Return Channel (ARC) Cables were introduced in 2013. These cables have an Ethernet channel as well as an Audio Return Channel, so they require fewer cables when wiring your system.

What Makes a Good HDMI Cable?

If you are looking for the best HDMI cables, there are several factors to consider: Price, build quality and compatibility. You will probably not need cables that are super-expensive, but a more expensive cable can be worth the money if it is built to better standards. The thickness of the wires matters, as do the materials used and the manufacturing process. Cheaper HDMI cables can fail prematurely when used with 4K video signals.

When shopping for a new cable, it is a good idea to look at customer reviews for the product. Also, check the return policies for these cables. While many stores have generous return policies, you want to make sure that there are no restocking fees or other stipulations.

The HDMI Forum has released the next generation of this technology, which is known as HDMI 2.0. These cables can transport video at higher resolutions and refresh rates, in addition to faster data transfers. They are backward compatible with previous versions of HDMI technology.

Other Options for HDMI Cables

In addition to the standard HDMI cables, you can also find a wide variety of specialty cables and connectors. For instance, you may want to get a cable with a right-angle connector if your setup does not allow for the cable to lie flat. You can also get cables that are quite long. These may be more susceptible to failure, but they can be handy in specific situations.

Consider what you need the cable for before buying one of these more expensive cables or going with a longer length.

You can also get adapters to switch between HDMI, DVI or even USB connections. These can be handy if you have a older device that does not have HDMI and you need to connect it to a newer TV. They can also help if you have two devices that you want to connect to one TV or device.

HDMI cables are very handy to have around. If you are installing a home theater system or setting up a video game system, you will need at least one. You may even want to get extra cables so you do not have to switch them out when you move things around. No matter what you plan to use HDMI cables for, you will find them to be very handy.

If you have an older TV without HDMI input, you might want to look at Component cables. Three RCA cables (Red, Green, Blue) carry a video signal in much the same way that HDMI does. While not as efficient, they do have the advantage of being able to transmit audio.

Look at the back of your DVD or Blue-ray player and you will probably see a set of three RCA connectors (Red, Green, Blue). These are the output connectors for video. Connect these to the corresponding colored inputs on the back of your TV. Once again white is ground, Red is Right Video, Green is Middle Video and Blue is Left Video.

Yellow is also found on some devices and will carry a video signal, in this case it is transmitted separately (without the other signals) and gives the Closed Captions for the hearing impaired.

You’ll need a special cable to connect these to your TV. They are not very expensive and can be had for as little as $1 or $2 at most discount stores.

Once connected, you will be able to get the video from any video source and display it on your TV. Now you can use the TV’s own controls to adjust the picture and sound.
