The Newest in HDMI Cabling
The newest form of cabling to hook up your multimedia devices — TVs, cable boxes, game consoles, DVD players and computer monitors — is known as HDMI, or High-Definition Multimedia Interface. These cables are capable of delivering full HD video and audio signals to all your devices simultaneously, meaning even 1080p video on your big TV will come across clear as day. HDMI cables represent a significant improvement over their predecessors in that they provide a 100 percent digital signal, have high bandwidth and are inexpensive.
The benefits to HDMI cables being all-digital are fairly straightforward. In older cable technology, an analog signal was transmitted, meaning that as cables grew longer the signal quality would degrade. In sending a digital signal through the cable, all that is being transmitted is a series of ones and zeros, meaning that the actual signal itself is either good or bad with no possibility for grainy picture or fuzzy sound. What this means for your home theater or office setup is you can have an HDMI cable of virtually any length and have no loss of signal. Besides that, it means that even the cheapest cables will perform to exactly the same standard as those expensive name-brand cables.
HDMI is capable of tremendous data throughput, meaning that it can send uncompressed video and audio without any problems. This high bandwidth is the reason HDMI cables can broadcast a 1080p signal to your TV without compression and do it in real time. HDMI is also capable of broadcasting high-definition audio on the same line as video, supporting up to eight channels of audio in addition to the video channel. This means that with just one cable, you can hook up both your TV and your 7.1 surround sound system, which is a great way to reduce home theater clutter.
At the end of the day, HDMI is the new standard for high-definition audio and video and it is here to stay. With the transition to all-digital television already here and HDTVs rapidly gaining popularity, more and more users are going to need HDMI cables to get the most out of their home theaters. The best part about HDMI cables is the fact that they are all-digital as well, so even the most inexpensive HDMI cable will provide everything you need in a cable, except for in the most extreme circumstances.
