Pay Attention to The Interface When Buy TV

These 10 kinds of video interfaces mentioned earlier, basically have been used in television except for three kinds(DisplayPort, IEEE 1394, BNC), and some TV sets may even have all of these seven kinds of interface, as a wise consumer, How we treat these interfaces when buy TV. To connecti with other electrical in the family, which interface is a must have one? Which interface is after elimination, and commonly less used out? Here we discuss these interfaces in three types.

1, RF, composite video and S-Video
These three interface developed along with the early analog TV technology, can only transmit "SD" video, which are essential in the era of CRT TVs, otherwise there is no way to watch TV, connect VCD, DVD machine. But now LCD TV has been so popular, and the cable television in family has access to digital set-top boxes, these interfaces have been largely useless.

From another point of view, we must guard against is that, with the "high-definition" concept of the popular now, many audio and video products promoted under the banner of the name of high-definition , which are bound inside some unscrupulous businesses, sold "SD" products in "high" price, how to judge it? There is a basic approach is: If this product's video input and output only these three kinds of interface (Part One), then this product must not support high-definition signals, the video display or output definitely not achieve the high-definition standard.

2, Chromatism
Chromatism interface is transfer analog video signals too, but the chromatism inputs support from the standard definition (480P, 576P) to HD (720P, 1080i, 1080P) video signal, so the basicly the DVD in the market are the preferred chromatism interface output, so we need to pay attention when buying TV, as far as possible to have this interface.

3, VGA, DVI and HDMI
These three interfaces are all high-definition interface, especially the HDMI interface, has been promoted as the only high-definition interface by the major TV manufacturers, seems as long as have a HDMI interface, the television immediately become a high grade! In terms of its
real effect actual use, the effect of DVI and HDMI is the same, VGA effect somewhat less certain, but this gap is not evident, especially work in resolution of 720P (1280X720), the three interfaces should not see any difference.

Taking into account fo the true high-definition products is gradually increasing, especially now that the LCD TV display resolution has been achieved even more than a computer monitor, you can easily connect the computer and television form a "high-definition" home theater, so we strongly recommended to purchase an LCD TV, be sure the TV has VGA, DVI and HDMI interfaces, especially the HDMI interface, the more the better.

Video Interface, How Much Do You Know?

There are many kinds of video interface in common life, from the RF to VGA then HDMI, some can only transmit analog signals, some can transmit digital signals, some transmit video and audio signal in one line, and some transmit video and audio signals separately. The following is some introduction about it.

1, RF
The antenna and analog closed-circuit connect TV is used radio frequency (RF) interface. As the most common video connection, which can simultaneously transmit analog video and audio signals. RF interface transmit the mixed-encoded signals of video and audio, the circuit on display device output picture by a series of mixed-signal separation coding, decoding. Due to the need for video, audio, hybrid coding, the signal will be interfere with each other, so it's quality output quality is the worst of all interfaces. Cable and satellite TV receiving equipment is also commonly used RF connections, but in this case, they transmit the digital signal.



2, Composite Video
Unlike the RF interface which contain the audio signal, composite video (Composite) usually use yellow RCA (Lotus socket) connectors. "Composite" means analog signals that transmit the brightness and color signal in same channels , but if a TV can not separate these two signals, there will be a shadow. Composite video is the widely used video interface in household appliances as it were.



3, S-Video
S-Video connection using Y / C (luminance / chrominance) separation-output, use the four-wire transmit the signal, the interface is the four-pin interface. two-pin grounded, the other two needles were transmitted light degree and chrominance signals respective. Because the transmission luminance and chrominance signals respectively, S-Video results better than composite video. You also can find S-Video nowadays in many video device like this USB video adapter. However, S-Video anti-jamming capability is weak, so the length of S-Video cable is better not to over 7 meters.



4, Chromatism
Chromatism (Chromatism) are usually labeled as Y/Pb/Pr, use red, green, blue three colors to mark each cable and interfaces. Green cable (Y) transmit luminance signal. Blue and red cables (Pb , And Pr) is the color difference signal transmission. The effect of chromatism is better than S-Video, so a lot of DVD and high-definition playback devices are used the interface. If you use high-quality wire and interfaces, even if A 10-meter-long cable, component cable can transmit good picture also.



5, VGA
VGA (Video Graphics Array) has another name known as D-Sub. A VGA interface has total pins of 15, which is divided into three rows, each row of five holes, is the most widely used interface types on the graphics card, the vast majority of graphics card comes with such an interface. It can transmit red, green, and blue analog signals as well as the sync signals (horizontal and vertical signals). Using the VGA connect device, cable length is best not exceeding 10 meters, but also to Note that connector is installed firmly or not, otherwise may cause the image appears a shadow.



6, DVI
DVI (Digital Visual Interface) port and VGA are the most common computer interface, and the difference from VGA is that, DVI can transmit digital signals, without carrying out several analog converter, so picture quality is very high. At present, many high-definition television also provides a DVI interface. Note that, DVI interface has a variety of specifications often, DVI-D (Digital) and DVI-I (Intergrated). DVI-D can only transmit digital signals, we can use it to connect video cards and flat-panel TVs. DVI-I can interchange in the DVI-D and VGA.



7, HDMI
HDMI (High Definition Multimedia Interface) interface is a recent development interface, it is transmit all-digital signal the same as the DVI. The difference is that HDMI interface can not only transfer High-definition digital video signals, but also can simultaneously transmit high-quality audio signals. Has the same function with the radio interface at the same time, but thanks to all-digital signal transmission, unlike radio frequency interface that poor quality of picture occurs.



8, DisplayPort
DisplayPort is a display interface released by Video Electronics Standards Association (VESA). As a successor to DVI interface, DisplayPort will add high-definition audio signals transfer support at the same time in transmitting video signals, while support higher resolution and refresh rate.

According to the design, DisplayPort supports both external display connections, and the built-in display connectivity. VESA want notebook manufacturers not only use DisplayPort to connect independent monitors but also use it directly connected LCD screen and motherboard for easy upgrades on notebook. To this end, DisplayPort interface is also designed to be very small, both to facilitate the use of laptops, but also allows the video card to configure multiple port.



9, IEEE 1394
IEEE 1394, also known as FireWire or iLink, it can transmit digital video and audio and machine control signals with high bandwidth, and very stable. Usually it is mainly used to connect digital video cameras, DVD recorders and other devices. There are two types IEEE 1394 interface: the 6-pin hexagonal interface and a small 4-pin square interface. Hexagonal 6-pin interface can provide power supply to device connected, while the 4-pin Of the square interface can not.



10, BNC
BNC (coaxial cable card ring interface) interface is mainly used to connect high-end home theater products, and professional video equipment like some BNC port CCD camera. BNC cable has five connectors, for receiving red, green, blue, horizontal synchronization and the vertical sync signal. BNC connector allows the video signal to reduce interference between each other can achieve the best signal response effect. In addition, BNC interface connect very tight due to specially designed, do not worry poor contact arising from interface loosening.

U.S. Telecom Operators

As every on knows, the strength of several major U.S. operators are very strong, and we can often see their names appear on the world's top 500 list. Next, we will mainly introduce the three major U.S. telecommunications operators, namely AT & T, VERIAZON, SPRINT-NEXTEL.

First, we would like to introduce to the U.S. telecom operator, AT & T, that is, once monopolized the telecommunications market in the U.S. . American Telephone Telegraph Company (AT & T) is an American telecommunications company founded in 1877, had long monopolized the U.S. long-distance and local phone market. AT & T, formerly known as the United States Bell Telephone Company in 1877 created by bell, the inventor of telephone. AT & T established plants in Thailand, Germany, Singapore. Have subsidiaries or joint venture in Italy, South Korea, Japan and other countries. In September 1995, the company's breakup into three separate companies: communications services companies, telecommunications equipment companies, computer information services company, and quit the field of personal computers. AT & T in the past 20 years, has had many spin-off and restructuring. Currently, AT & T is the largest U.S. local and long distance telephone company, it headquartered is in San Antonio, Texas. The company attaches great importance to research and develop new products. April 9, 2009, "Forbes" magazine online edition assess latest Global 2000 enterprises according to firm size, profits, assets, market value of the , AT & T ranked No. 7

The next we want to say is the U.S. operator VERIAZON. Verizon operate telecom & wireless business in 45 countries in the U.S., Europe, Asia, the Pacific and other global areas, listed on the New York Stock Exchange. Verizon is establish by this: two United States original region Bell operating companies - Bell Atlantic and Nynex merger, establish the BellAtlantic, after the establishment, BellAtlantic merge with the independent telephone company GTE in June 30, 2000 again, after the company merger, Verizon became the United States in one fell swoop the largest local phone company, the largest wireless communications company, the world's largest print Yellow Pages and online yellow pages information provider. February 2005, the second-largest U.S. mobile operator Verizon acquisition of the second-largest long-distance fixed-line telecommunications operator MCI, after the acquisition is completed, Verizon became the second full service operators. The acquisition lasted 11 months, during this period share price fell 13.4% (corresponding to the S & P500 index was up 7%), as of April 21, 2008 stock price than the tender offer Day (January 6, 2006) was up 17% (corresponding to the S & P500 index was down 9%).

Then we talk about U.S. operators SPRINT-NEXTEL which is already in third place.

Sprint is the fourth-largest U.S. wireless operator. Sprint is a global communications company provide service to 2,600 million commercial and residential customers in more than 100 countries. December 15, 2004, the United States third-largest mobile operator Sprint announced a 35 billion U.S. dollars acquisition of the fifth-largest U.S. mobile operator Nextel, the combined company named Sprint Nextel. Sprint Nextel is a place with 40 million customers in the United States the third-largest mobile operator.
