HDTV Cables

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.

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.

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. 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. 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, but is not readily available to consumers. When compared with SDI cable, DVI and HDMI cables are poorly designed and can be availed from the market.

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.
