HDTV Cable Types

Cables are electric conductors covered with insulating material. They are used to connect different components of a system such as connecting a DVD player with a TV. 

Different types of cables like data cable, network cables, high voltage electric cables, fiber optic cables etc. are being used today. The use of these cables has changed the way information is transferred from one source to another. 

HDTV cable, also known as high definition television cable, is a specially designed high-end digital cable that hooks up an HDTV set top box and an HDTV television set. HDTV is the latest innovation in DTV signals and transmits pictures with a high resolution and clarity. The popularity of HDTV cable has made the HDTV, the latest trend in television technology.

The recognition of the HDTV television has led to a great demand in HDTV cables in the market. Currently, the market is flooded with different brands and types of HDTV cables. The Monster Cable, Cobalt Cable, and Blue Jeans Cable are some of the leading brands of HDTV cables.

HDTV composite cables give many nightmares. To most people, the idea of getting HDTV is exciting and fun. The quality of the picture, the beautiful design of most HDTV sets and the envy from the neighbors are just some of the reasons that drive people to their local store to pick out the newest HDTV sets.

Generally, all brands of the HDTV cables come with robust and highly flame-retardant outer mesh, which protects the cable from external damage and conductor. For maximum conductivity and bandwidth, most of the HDTV cables come with copper conductor, plated with sliver. To protect the signals from the interferences of RFI (Radio Frequency Interference) and EMI (Electro-Magnetic Interference), the HDTV cables are usually coated with high density quad-layer shielding. The quad-layer shielding is injected with nitrogen gas to maximize the conductivity and bandwidth of the HDTV cables.

Composite cables are simply those three-colored cables that you get whenever you buy a new television, a video game system like a Playstation or Nintendo, or even a high-end stereo system. The cables have three ends, a white male end that is for half of the stereo-quality audio, a red male end plug that is for the other half of the stereo-quality audio, and a yellow male end plug that is for high-quality video. With HDTV Composite Cables, using them is a snap. While you need to hook up your HDTV cable box to your TV, just plug yellow to yellow, red to red and white to white. If you need to hook up that brand new surround sound system to your TV, just plug yellow to yellow, white to white, and red to red. Just use the HDTV composite cables and you’re set to go.

Signals passed through the HDTV cable connections can be either analog or digital types. To meet this need, the HDTV cables come in two types; analog HDTV cables and digital HDTV cables. Digital HDTV cables can be availed in three forms; SDI (serial digital interface), DVI (Digital Video Interface), and HDMI (High-Definition Multimedia Interface). SDI cable is highly robust, 75 ohm video coax cables. DVI and HDMI cables are poorly designed if compared with SDI cable. The analog HDTV cables are 75 ohm video coaxial cable, with RCA, BNCs or HD15 plugs at the end. The signal passed through this cable can either be ordinarily component video or RGB.

Whether it is analog HDTV cables or digital HDTV cables, it is always recommended to purchase the cables which are sweep-tested by the manufacturer. The sweep test will guarantee that the cable will not show any excessive or uneven attenuation within the required frequency range. Therefore, carefully selected HDTV cables will provide clear and high quality pictures on your HDTV televisions.
