Cable Subscribes Get Connected to HDTV
from: George PhillipsHDTV 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.
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.
