HDTV Digital IDE cables exist or Serial Digital Interface. However, this cable is strong yet commercially available. On the market are the DVI (Digital Visual Interface) and HDMI (High-Definition Multimedia Interface).

two-way connection between computers and monitors is possible through dual-channel versions of DVI. These connections carry video only. Audio must be carried by other cable HDTV.

HDMI carries uncompressed digital audio between devices such as an STB and a display. Small connectors are used with HDMI. The cable HDTV HDMI also enables bi-directional interface. HDMI uses a 19 pin connector to link one or more 29-pin connector to the double bond.

Cable for connecting DVI and HDMI devices are also available.

DVI and HDMI are characterized by very short lengths of cable because it is designed to accommodate a copy-protection system. HDTV Digital cable uses twisted pair cable coaxial cables used analog HDTV cables. DVI and HDMI work smoothly over short distances, but some low-quality cables fail more than ten feet.

There is virtually no digital HDTV cable works beyond fifteen meters. DVI cable preformed up to 10 feet long are available. Longer lengths require special materials and are expensive. Although interconnections produce high quality digital video and audio, running long distances is the limitation of digital HDTV cables.

VGA today generally refers to the type of cable used to carry the signals of the screen, regardless of actual graphics system in use. It features 15-pin plug to three rows of five. The plug has two screws, one on each side of the pin holding it in place in the socket. These screws have sharp ridges which means you can tighten and loosen by hand instead of needing a screwdriver.

There is a wide range of VGA cables available at different prices. More expensive models offer features such as gold plating on the plugs, or shielding to prevent the individual wires to cause interference. However, many people believe that these improvements offer little and generally not worth the extra cost. As a general rule, the difference in image quality between a VGA cable very cheap and moderately priced one will be much more significant than between a VGA cable and a fairly expensive price. It is also worth making sure you buy the shortest cable that meets your needs as this will prevent degradation of the signal.

Besides computers, a VGA cable can be used with game consoles, including Microsoft Xbox 360. This allows the console to be used with a computer monitor, which can provide better image quality than the old cathode ray televisions, particularly for computers that have fine detail or small text. However, the quality will not be as good as with a television set that can be connected to the console via a component video connection or a HD input as HDMI. This means that more than one option is provisional.

As the term suggests,video cable is used to transmit video signals,which connects display devices and media player devices such as DVD,HTPC,VCD.Video cable has the following categories:
AV cable:it is the oldest video cable transfering analog video signal,of which both ends are lotus head(RCA head).Currently,DVD players and television sets all have this interface and you needn’t lay such a line when decoration.
S terminal cable:it appears a few years ago and the quality is better than AV cable.The interface is circular similar to the PS2 mouse head.Because it is behind the times,don’t recommend.
3 component cable:currently,it should be the best video cable which transmits analog signal and is better than S video cable on quality.It appears on new DVD players,high-end TVs and home-used projectors.If your media player device and display device are distant,consider it when decoration.
VGA cable:it is also a video cable,mostly seen in computers.But with the increasing amount of video data,VGA cable are poor in quality and too long cable will lead to snow on devices when the resolution is more than 1600X1200.Why mentions VGA cable? That is because HTPC comes into the home theater,all the projectors have VGA Interface.So,it must be considered.
DVI cable:full name is Digital Visual Interface,the latest digital video cable transmitting all-digital signal with uncompressed technology,of which the maximum transmission speed is 8Gbps.It has been supported by most manufacturers currently.Its interface includes 24 +1(DVI-D) and 24 +5(DVI-I) type.DVI-I simultaneously supports digital (DVI-D) and analog signal(VGA signals)transmission.In general,HTPC graphics cards support DVI-I interface and liquid crystal displays and projectors support DVI-D interfaces.DVI-I interface isn’t compatible with DVI-D interface because of four needles on DVI-D interface,but we still can use a DVI-I to DVI-D switch converter to solve the problem.
HDMI cable:full name is Hi-Definition Multimedia Interface,a digital video cable newer than the DVI cable transmitting all-digital signal with uncompressed technology,of which the highest transmission speed is 3.95Gbps.HDMI can not only transmit video signal,but also digital audio of 192kHz 8-channels and 96kHz mono.There aren’t too many devices supporting HDMI,whose interface can convert with DVI interface.
In conclusion,in order to support all display devices like general TV,plasma,LCD TVs,rear projection,LCD cinema projector,which cable we should lay?
If you want to be compatible with all the equipment,the best chioces are the most common VGA cable,analog component cable,DVI cable.Less equipments support HDMI interface on the market,if has,convert the signal on DVI cable via a DVI-HDMI switch.

Have you ever considered what  a Printer USB cable, or any universal connecting cable really is? Without this cord to connect your computer to external devices , many of the technology tools we use would have limited value.

USB is available for every laptop, desktop, or printer, and eliminates the need for additional power supply.An often unconsidered feature of the USB cord is compatibility with multiple operating systems. Universal connecting cables are supported by all systems made today. Only older systems may deviate from this standard.

A converter cable permits a printer to be connected to the USB port, enabling rapid data transport, far beyond the speed of a typical parallel printer port.

Because of this, costs are reduced on external accessories, and several peripheral devices can be connected at the same time, up to the maximum reserved bandwidth.

Printer cables may need to operate with specific ports on peripherals. For converting the signal from the printer USB cable to a parallel port, a specific converter cord can be purchased. Sabrent makes a model which communicates with PC’s and Mac’s, desktop or notebook.

A converter cable permits a parallel printer to be connected to the USB port, enabling rapid data transport, far beyond the speed of a typical printer port. This reduces time spent finishing a job, by getting it to the printer faster.

RF is the RF current, it is  high frequency AC electromagnetic wave in short. Changes of less than 1000 times per second is known as the low frequency AC current, more than 10,000 times as high frequency current.RF is such a high frequency current.

RF technology takes a  irreplaceable role in the wireless communication field.

In electronics theory, the current flows through the conductor, the magnetic field will form around the conductor; alternating current is  through the conductor,and the alternating electromagnetic field will form around the conductor, known as electromagnetic waves.

When the frequency of  electromagnetic wave  is less than 100khz, waves will be absorbed by surface, can not form an effective transmission. When the frequency is  higher than the 100khz, the electromagnetic waves can spread in the air, and reflect through the outer edge of the ionosphere, forming the long-distance transmission capacity. We call the high frequency electromagnetic waves with long-distance transmission capacity RF.
