Get Wise and Digitize - HDTV Style
from: George PhillipsHigh definition television, or HDTV for short, is the new way to view broadcasts and movies in the home. It is popular because not only are more networks offering programming in HDTV, but also because high definition offers views a clearer, true picture with outstanding picture resolution. Most consumers are catching on to HDTV and are spreading the word to get wise and digitize-HDTV style.
There are many advantages to switching to HDTV over keeping traditional analog sets. HDTV offers a brighter, clearer picture, and as it becomes more popular there are more choices available to purchase. In the past, high definition sets were generally large and were more suitable for large home movie theaters with lots of space. Now, the screens are getting smaller, making HDTV a good choice for smaller areas with less space.
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 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 switching over to HDTV broadcasts, it is important to first determine what signals are available in the area and what kind of equipment is needed to get those broadcasts.
Not all networks offer all shows in HDTV. The FCC gave all broadcasters an extra channel to broadcast in HDTV. Some networks offer certain shows and specials. Sporting events in HDTV are also popular choices for HDVT broadcasts. 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 receive over-the-air broadcasts, an antenna is needed to receive the signal as well as a high definition set with a built-in HDTV tuner. Otherwise, a high definition-ready television with a separate tuner is necessary. 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, contact the local cable or satellite provider to see what is offered in a particular region.
Digital satellite television is another popular and choice in the United States. Most cable subscribers can have access to digital satellite. DIRECTV and DISH Network 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, it will be necessary to have a combination of either satellite and an antenna, or a satellite and a cable to receive all the channels you wish. In order 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.
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. When upgrading to digital cable, it is probably necessary 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 HDTV’s are called digital cable ready and have a built in card slot for a Cable CARD. The card allows the TV to get HDTV and other digital cable without a separate converter box.
Important Notice Concerning DTV and HDTV: Although many TV systems have already complied with earlier rulings for changing all transmission to digital TV, there still is doubt as to when overall compliance will be reached. Earlier it was scheduled for late 2006, but it is doubtful if this happens.
