High definition television is the newest revolution in the technology for watching television. However, understanding the difference between the current system and high definition television is important. The difference is the resolution; the quality of high definition television is 5 times better than the usual DVD. The minimum resolution for HDTV is 720p but better should be 1080p. Furthermore, the HDTV requires a Blue Ray Disk player and Blue Ray Movies to take full advantage of the better picture quality. Older movies can't give you this quality because of the cameras that were used at that time they made the movie were not HD and it is not just because of the type of television that gives the resolution of HDTV.

High-definition television is fantastic if the system to support it is present. There are actually three different options to choose from when deciding between cable or a satellite system. They are obviously cable, satellite, and the old fashioned TV antenna.

Cable depends on whatever local cable company provides in the way of high-definition channels. Some cable companies only offer a handful of channels that are available in high-definition and there is an extra charge for this service. On the other hand, one big advantage for cable is that there usually isn’t an extra charge for the local channels and most of them are now available in HD.

With satellite systems a huge factor to be considered is the cost of the equipment that is needed. Like a HD receiver is needed to be able to view HD channels. Also, with satellite there is an extra charge for local channels.

Lastly, the older TV antennas more or less snatch the signal out of the air. Consequently, when an HD receiver is hooked up to a regular television it will pick up local channels in HD. This saves a great deal of money and with new services like Blockbuster All Access or The Movie Download downloading or renting movies is a nice alternative

In a nutshell, High-definition is the future of television and the benefits of cable is there is no more equipment to buy and the local channels are included. The benefits of satellite are that there are many more channels, but there is an extra fee for the local channels. The benefits of the TV antenna are that it is inexpensive and the local channels can be watched in HD.
