HDTV or high definition television is becoming a popular choice for viewers. Broadcast networks and cable companies are trying to keep up with the demand of high definition. Many cable networks are starting to offer more viewing choices in high definition.

As the popularity of high definition broadcast rises, the amount of available broadcasts also go up. Currently in the United States, there are about forty channel networks that broadcast in high definition. These networks include the major movie channels such as HBO and Showtime and other channels such as the ESPN sports channel and the Discovery channel. Japan, Australia and South Korea are all leaders in bringing HDTV broadcasts to consumers. In Europe, HDTV is just beginning.

Some networks often offer viewers certain prime time specials and sporting events in HDTV rather than their entire broadcast. The four major networks usually offer professional football, championship baseball, basketball and NASCAR in high definition. In addition, they offer television specials and awards shows in HDTV.

Screen resolution from a high definition TV broadcast is almost five times as sharp as conventional broadcasts. High definition has double the lines of resolution compared to a traditional analog TV set. While a traditional analog set can only display 525 lines of resolution, HDTV technology takes this one step farther. HDTV broadcasts can display 1080 horizontal lines of resolution. This makes a huge difference in the picture clarity and quality. Often with big screen analog broadcasts, the picture is severely degraded because of the resolution lines.

There are three ways to receive high definition signals: over-the-air (OTA) broadcast that is usually provided by local networks and PBS affiliate stations, digital satellite TV providers such as DIRECTV, dish networks and by HDTV via cable. When you are ready to subscribe to HDTV broadcasts, you must first determine what signals are available in your area and what kind of equipment is needed to get those broadcasts.

To receive over-the-air broadcasts, you will need an antenna for your signal and a high definition set with a built-in HDTV tuner or you will need a high definition-ready television with a separate tuner. Many of the televisions on the market today fall into this category. The OTA broadcasts are digital broadcasts. Over 1500 channels around the United States are currently OTA. To receive OTA broadcasts, you will need to call your local cable or satellite provider to see what is offered in your region.

Digital satellite television is another popular choice in the United States. Most all everyone can have access to digital satellite. DIRECTV and DISHNetwork are both popular HDTV satellite providers that offer limited channels in HDTV. There is a new service called VOOM that offers over thirty channels. Before subscribing to a digital satellite service check to see if local channels are offered. Many times subscribers are unable to access local network stations using satellite. If this is the case, you will need to have a combination of either satellite and antenna or a satellite and cable to receive all the channels you need.  To have access to digital satellite services, it is necessary to have a high definition-ready television, an HDTV compatible satellite tuner or receiver and a dish antenna.

High definition cable is another very popular choice. The cable television providers are beginning to offer a wider range of HDTV programming to keep up with the consumer demands. Most of the HDTV programming offered by cable TV providers are available nationwide, but are most commonly found in bigger city markets. Remember that digital cable and HDTV from cable is not the same thing. Digital cable generally means that there are more available channels and that the picture quality is better than traditional analog television, but not as good as high definition. However, most digital cable providers will begin to provide HDTV in the very near future. If you upgrade your digital cable, you will probably need to get an upgraded cable box from your cable provider. In order to access this service, you will need the HDTV cable box and a compatible TV. Some new HDTVs are called digital cable ready and have a built in car slot for a CableCARD. The card allows the TV to get HDTV and other digital cable without a separate converter box.

HDTV or High Definition Television offers many benefits over traditional analog television. High definition television has excellent digital superiority, crisp detail, progressive scanning, digital audio, a wider viewing area and better quality DVD playback. The FCC is pushing broadcasters, electronic manufacturers, and consumers to make a complete switch to high definition television by 2006. Many are ready for the change. Are you HDTV connected?

The issue of choosing HDTV over analog television came around 1987 when the FCC issued a ruling indicating that all analog televisions would become obsolete in 2006. The Japanese had developed a successful high definition television and the United States wanted to come out ahead with the HDTV technology. As a result a group of American electronics companies that manufacturer televisions formed the “Grand Alliance” by inventing digital HDTV.

In 1990, the FCC announced that HDTV would be broadcast at the same time as existing NTSC broadcasting service. The idea was to give television broadcasters additional channel space to broadcast in both analog and digital. The old channels would then become obsolete. To make this work, all televisions would have to convert to digital. All televisions made since would suddenly become obsolete unless a converter was purchased and installed.

The converters for enabling traditional analog televisions to digital cost around $100. While no one would argue that high definition television is far superior to analog with a clearer and brighter picture, it is expensive.

More and more consumers are getting connected to high definition. As the technology to make smaller HDTV sets rises, the cost of these televisions come down enabling more people to purchase the sets. In addition to the cost of the actual television, the price of enhanced cable or satellite service must be considered before getting connected to HDTV.

High definition does have its benefits besides a better picture resolution. HDTV has none of the imperfections caused by a traditional analog broadcast. There is no snow from weak signals, no double images from ghosting and no picture sparkles caused by impulse noise.

In addition, HDTV offers viewers the ultimate in viewing experience when connected to a surround sound system. The wide-screens offered by HDTV and the complete audio are just like seeing a movie in a movie theater. There is no part of the viewing area cut off at the top or bottom when using HDTV.

As the popularity of high definition broadcast rises, the amount of available broadcasts also go up. Currently in the United States, there are about forty channel networks that broadcast in high definition. These networks include the major movie channels such as HBO and Showtime and other channels such as the ESPN sports channel and the Discovery channel. Japan, Australia and South Korea are all leaders in bringing HDTV broadcasts to consumers. In Europe, HDTV is just beginning.

Some networks often offer viewers certain prime time specials and sporting events in HDTV rather than their entire broadcast. The four major networks usually offer professional football, championship baseball, basketball and NASCAR in high definition. In addition, they offer television specials and awards shows in HDTV.

To get connected in the world of high definition television, you must first purchase an HDTV-ready or an HDTV capable television. There are several to choose from. Rear projection, plasma and LCD are all types of HDTV. When a television is labeled as HDTV-ready that means the TV has an HDTV tuner built in. This enables the TV set to get over-the-air high definition signals from local networks. HDTV-capable means that the TV set is able to receive high definition signals, but only with the use of an HDTV converter box that is available from the cable or satellite company, or a digital tuner and over-the-air antenna. A converter box usually costs between $5 and $10 per month, or some are available for purchase for several hundred dollars.

The last and probably the most important step of getting connected in high definition will be to watch a broadcast in HDTV. Major networks have some programming in high definition, but many do not. High definition programming will be separate channels from the standard non-high definition channels. It is important to know whether or not the channel and programming you are interested in are offered in high definition.

Shopping for a new high definition television can be confusing if you do not understand what is on the market. There are many types of HDTV available today. Long gone are the days of simply picking any television because it is the right brand or the right size. There are LCD screens, rear projections, flat screen and plasma sets. There are also HDTV-capable and HDTV-ready sets. What does all this mean and how do you go about picking what is right for you?

Consumers can purchase plasma, LCD (liquid crystal display), DLP (digital light processing) or LCOS (liquid crystal on silicon), which are all types of monitors. There are also projection displays to consider. They also come in LCD, DLP, and LCOS. Many viewers prefer the wall display monitor that either plasma or LCD offers. But, these are usually most expensive of the high definition sets, especially the ones that are sized between 40 to 70 inches. Lower on the cost spectrum, but equally good, are the LCD displays that are sized at 42 inches and under.

High definition televisions are popular because they offer a brighter, clearer picture resolution and work well with a surround sound audio system. Movie enthusiasts love HDTV because it offers the whole picture on the screen instead of cutting off part of the picture at the top or bottom.

Screen resolution from a high definition TV broadcasts is almost five times as sharp as conventional broadcasts. High definition has double the lines of resolution compared to a traditional analog TV set. While a traditional analog set can only display 525 lines of resolution, HDTV technology takes this one step further. HDTV broadcasts can display 1080 horizontal lines of resolution. This makes a huge difference in the picture clarity and quality. Often with big screen analog broadcasts, the picture is severely degraded because of the resolution lines.

One thing to consider when purchasing a new HDTV set is to think about the differences between a television marked HDTV-capable and HDTV-ready. HD-ready sets have the HDTV receiver and/or decoder built-in. This enables the TV set to get over-the-air high definition signals from local networks.

The HD-capable set requires the addition of an external receiver or decoder in order to receive digital broadcasts. HDTV-capable means that the TV set is able to receive high definition signals, but only with the use of an HDTV converter box that is available from the cable or satellite company, or a digital tuner and over-the-air antenna. A converter box can be rented cheaply each month or you can purchase one for a few hundred dollars. Many HDTV sets available on the market now have built-in digital tuners that allow you to view the free digital broadcasts from major local networks.

Additionally, converter boxes that are compatible with analog televisions can be purchased. These special converter boxes or adapters cost approximately $100. The picture will be similar to analog, but will be in digital format. The only downfall to this is that if there is a weak digital signal, there could be no picture on the screen at all. HD-capable televisions are generally less expensive than that HD-ready sets.

To receive over-the-air broadcasts, you will need an antenna for your signal and a high definition set with a built-in HDTV tuner or you will need a high definition-ready television with a separate tuner. Many of the televisions on the market today fall into this category. The OTA broadcasts are digital broadcast. Over 1500 channels around the United States are currently OTA. To receive OTA broadcasts, you will need to call your local cable or satellite provider to see what is offered in your area.

Something to keep in mind when shopping for your new HDTV set is to find out what programming is available in your area for high definition. Most all of the networks have two channels, one in analog and one in high definition. They are not the same. Unless your television is either HDTV-ready or capable, you will not be able to view the high definition broadcasts.

Also, although nearly all networks do broadcast in high definition, many times they will not show all programs in high definition. Often, the networks broadcasts certain primetime specials and major sporting events. It is important to find out what is available in your area. Many people are disappointed to find out that their favorite shows are not always offered in high definition.
