high Definition Television or HDTV is the latest on TV technology. HDTV is better than most of the available TVs today in many ways; in sound, resolution and imaging. There are breakthrough technologies at work in a HDTV that made it more recommendable than the latest digital TVs.

HDTV is a digital television or DTV. Eighteen formats have been assigned to digital television, and presently, only six of the eighteen are considered HDTV. A true HDTV may have either 1080 interlaced lines or about 720 progressive scanned lines.

HDTV is not comparable to SDTV or Standard Definition Television. Though SDTV offers consumers a relevant improvement in picture resolution as compared to the usual digital TVs similar to a comparison of DVD to VHS viewing, it cannot compete with HDTV in the quality of both audio and video.

Favorite HDTV Features

Various technologies implemented on various HDTVs outclassed most of the technologies in digital TVs:

1. HDTV have about twice the picture resolution in terms of the vertical and horizontal as compared to any analog or digital TV available today. This makes the HDTV picture sharper and clearer than most of the TVs today.

2. HDTV have a wider screen with a screen or aspect ratio of about 16: 9 as compared to the 4:3 screen or aspect ratio of most analog or digital TVs.

An aspect ratio is the width of a picture screen relative to its height. So an aspect ratio of 4:3 means that the picture screen is 4 feet wide and 3 feet high. This means that the best picture screen available for HDTVs today is 16 feet wide and 9 feet high. This large screen will provide more detail resulting in a crisper image.

3. HDTV have also managed to reduce motion artifacts that includes ghosting or dot crawl on the screen.

4. HDTV also have a Dolby A3 Sorround System. It offers 5.1 independent channels of CD-quality stereo sorround sound. This is also referred as AC-3.

All in all, HDTVs displays pictures in a higher resolution with greater detail than most of the analog or digital TVs. Images are sharper and clearer and HDTVs offers the best digital sound available to the consumer.

The HDTV Converters

HDTV converters are used to directly convert digital signals from a satellite broadcast into HDTV format for viewing in most analog TVs instead of implementing an analog conversion that is inferior in terms of picture and image viewing.

Simply put, HDTV converters avoid analog conversions of digital signals resulting to a much improved picture on analog TVs. The picture and image on an analog TV that used a HDTV converter is similar to the picture and image from a DVD movie that is played in an analog TV.

SImilarly, HDTV shows from satellite broadcasts can be shown in an analog TV using the HDTV converter. The picture and image will be inferior but at least are much more tolerable.

The Best Set-Up for HDTV

The most ideal set-up for HDTV is by receiving a pure digital signal directly via cable either by DirecTV or by the Dish Network. These pure digital signals are received by a digital receiver and are displayed on a digital TV set.

Consumers that are looking for the best can opt for a front or rear projection HDTV set or also a plasma set with a similar 16:9 aspect ratio.

People who wants to test the HDTV technology but are not really sure of what they really want can opt for a HDTV-ready digital TV instead. HDTV-ready TVs are much more cheaper than the actual HDTVs.

These HDTV-ready digital TVs have the standard aspect ratios of 4:3. It lacks, however, the HDTV decoder that will interpret the HDTV signal. A stand alone HDTV decoder, however, is available if a consumer wants to be able to upgrade the display for HDTV broadcast.

The out of the box HDTV systems usually have a high definition tuner built inside it. Though, the addition of high definition tuner makes it more expensive, it nonetheless an advantage that is made for the convenience of the most enthusiastic viewer.

In recent years many persons have signed up for satellite TV programming. A lot of them used to have cable TV; but made the changeover to satellite television. Dish Network TV has nearly 14 million subscribers currently. What has caused so many former cable subscribers to switch over to Dish Network Satellite TV?

For one thing, cable TV is very expensive compared to satellite TV. Cable rates keep climbing nearly monthly. The typical cable TV monthly bill runs around $42.76 a month; while Dish Satellite TV has packages that begin at just $19.99 per month. Also, if you want a lot more programming channels with cable, expect to pay over $100.00 for your monthly programming fee.

Cable television companies use a combination of analog and digital signals, which often produce a very fuzzy picture. Satellite television firms such as Dish Network on the other hand use all-digital signals which produce a crystal clear picture which is much easier to watch and to enjoy.

Another problem with cable television is that the cables are under ground where animals can eat and knaw away at the them. This can and does lead to pixelization problems. With satellite television, the coaxial cable runs straight from the dish on your roof down and straight into your house.

Another problem with cable is that you can’t always get cable TV where you live. If you live in a remote or mountainous area for instance then most likely you won’t be able to even get cable TV service where you live. Also, laying down cable takes a very long time and many cable companies simply haven’t gotten around to doing it in your area. On the other hand Dish TV satellites are always up there in the sky beaming down their programming signals. Dish TV satellites hover above the earth’s equator at an altitude of 22,300 miles in what is known as geosynchronous orbits (also know as Clarke orbits). These were named after Sir Arthur C. Clarke. This means that virtually anyone can sign up for and subscribe to their satellite TV service.

Another problem area with cable is that often times you will experience down times where you have nothing but a blank screen to look at. A study done by JD Power and Associates shows us that cable TV subscribers have up to a 5% downtime on their televisions service. That number is only 1% for satellite television viewers. And whey your cable TV service goes out – it can be HOURS before your service is restored again. By now, it should be obvious to you why satellite TV is vastly superior to cable TV. Satellite Television costs far less than cable television, satellite TV has a way better picture quality, satellite TV has a way better audio sound quality than cable TV does, satellite TV has far less downtime than cable television has and the list goes on and on. No wonder that more and more people are switching to satellite tv by the day.

HDTV cables are conduits of HDTV transmissions. There are two kinds of HDTV connections: analog or digital. Various HDTV cables are used for these connections. They should be of good quality and well installed to guarantee a fully reliable system.

Analog HDTV cables

Analog HDTV signals are either RGB (usually RGBHV) or component video (Y/Pb/Pr).

Component connections are made using RCA connectors. These connectors transfer SDTV NSTC signals from external devices such as DVD or VHS to HDTV displays. Component cables are usually color coded: green for Y, blue for Pb and red for Pr. Audio cables are also color-coded: red for Right audio and white for Left audio.

Seventy-five (75) ohm video coaxial cables are suitable for these applications. These HDTV cables end with RCA plugs, BNCs or VGA monitor plugs.

HDTV analog signals are ten times stronger than NTSC. HDTV signals scale up to 35 MHz while NTSC reaches only up to 3.5 MHz. It is important that HDTV cables which connect devices together maintain a consistent impedance of 75 ohms. HDTV cables which do not meet proper specifications will cause ghosting or “ringing” of projected images because portions of the signal issues back and forth within the cable instead of being smoothly delivered to the screen.

Before purchasing analog HDTV cables, make sure that the device has been sweep-tested at least up to 105 MHz. Also, check that the impedance tolerance is 75 ohms within +/- 1.5 ohms.

Digital HDTV cables

Digital HDTV cables exist in SDI or Serial Digital Interface. However, this very strong cable is still commercially unavailable. In the market are the DVI (Digital Visual Interface) and HDMI (High-Definition Multimedia Interface ).

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

HDMI carries digital uncompressed audio between devices such as an STB and a display. Smaller connectors are used with HDMI. The HDMI HDTV cable allows for bi-directional interface also. HDMI uses a 19 pin connector for single link or a larger 29 pin connector for dual link.

Cables to interconnect DVI and HDMI devices are also available.

DVI and HDMI are characterized by very short cable lengths because they designed to house a copy-protection scheme. Digital HDTV cables use twisted-pair cable not coaxial cables which analog HDTV cables use. DVI and HDMI work without problems over short distances but some low-quality cables falter beyond ten feet.

Practically no digital HDTV cable works beyond fifty feet. Pre-formed DVI cables up to 10 ft. in length are available. Longer lengths require specialized materials and are expensive. Although digital interconnections produce highest video and audio quality, running over long distances is the limitation of digital HDTV cables.

Other cables

S-Video Cables. are used in some televisions to improve picture quality of NTSC signals. Audio must be interconnected separately using RCA cables. S-Video cables are available in any length.

F Cables are coaxial cables with F-connectors used to connect to antennas or satellite dishes to the TV cable system. Several possible cables are selected depending on the length needed. RG-59 is acceptable for short lengths but a low-loss cable is needed for roof-top antennas.

Mini DB 15 RGB Monitor Cables are used to connect PC to HDTV displays with analog RGB interfaces. These cables extend up to 5 meters. Special cables are needed beyond this length. Screw locks secure the connectors to warrant a firm connection.

Firewire/1394 is designed for digital video connections. Audio and video are carried together. The four pin version is the most common but six pin versions are also available for some devices. Prefabricated HDTV cables like these are up to 3 meters.

Dolby Digital audio in SPDIF format is frequently transmitted in optical form. Fiber link, an optical fiber cable which is also called “optical audio output cable”, may be employed to send these transmissions to the decoder in the audio system. Excessive bending or twisting of these cables must be avoided as not to break the fiber inside.

Cables are crucial in making sure the listeners or viewer maximizes his homes video or audio system. Poor cables are normally susceptible to noise and interference that negatively affects the signals produced by the source unit. In addition, low quality cables will rob the consumers of all the benefits of investing a huge amount in a particular system.

A considerable number of A/V components do have all the cables needed in a setup, while there are those that contain a cable that is too long. Cables that included by a source manufacturer do not normally measure up to the quality of those made by aftermarket companies. Using the right cable is one of the needs in order to maximize your HDTV viewing pleasure.

Enter digital video interconnects

The development of digital video connections resulted from the adoption of digital video sources and displays. There are only two digital video options and these are HDMI cables and DVI cables.

HDMI and DVI cables will greatly benefit TVs that have a “fixed’-pixel” display. These cables allow video signals to remain digital up till they reach the screen. Digital pictures do have the snowy and grainy effects normally seen in analog pictures. Both cable types can carry HDTV video signals. The demand for the said cables has sharply increase over the past two years, as more and more people are using HD-compatible TVs and HDTV tuners.

Here are some of best selling HDTV cables in the market today.
