The first task is to determine if an HDTV signal is available in your area, either by satellite or cable.
You must be able to receive a signal in order for an HDTV to provide the clear, detailed pictures for which the technology is known.
Call your local cable provider or go online to find out if HDTV signals are available, and if not, when they will become available to you.
In larger cities, not only can you receive national network and cable shows in HDTV format, but also locally produced shows, such as news.
If HDTV signals and channels are available, you can now begin to consider purchasing a television that is HDTV compatible.
