Television: HDTV

High Definition Television

HDTV Reception
"What channels can I receive in digital or high definition in my local area?"

There are five ways to receive High Definition content. The options are listed below:

Satellite

A satellite company such as DirecTV or Dish Network will sell you HD programming. If you go this route, you will have to pay a little extra to receive local channels if you wish to watch your local network broadcasts. If you decide to get HD from a satellite company you will have to:

  1. Get a subscription from the specific satellite company that includes HD programming.
  2. Buy a satellite dish that is capable of receiving HD signals from the satellite company you wish to receive HD service from.
  3. Buy a Set-Top-Box that is capable of decoding High Definition channels and is compatible with the specific satellite provider you choose.
  4. Buy a High Definition TV to view the signals.

Local Cable

Cable TV companies provide HDTV broadcasts. Two companies currently providing HD broadcasts are Comcast and Spectrum. AT&T is in some areas offering HDTV as well. If you decide to do this you will have to:

  1. Get a subscription from the cable provider who supports HDTV and drops a coaxial cable into your house.
  2. Buy or rent a Set-Top-Box that is capable of decoding High Definition channels and is compatible with the specific cable company you choose.
  3. Buy a High Definition TV to view the signals.

Many people are confusing Digital Cable with HDTV and DTV. These are two completely different things. If you get Digital Cable, this usually does not mean you are already set up to receive DTV and High Definition signals. (Though it is possible)


Over The Air

OTA stands for Over the Air. You set up an antenna to get broadcasts from a local TV tower. If you get signals OTA you will not have to pay a subscription to a cable or satellite company and the programming is completely free. This does, however, limit you to only a few local channels and is why most people receiving television programming OTA also get programming from a cable company or satellite company as well. If you decide to get OTA HD programs, you will have to:

  1. Buy (if you do not already own) an antenna that is capable of receiving signals from broadcast towers near you. To find out what type of antenna you might need, see Antennas.
  2. Buy a Set-Top-Box that is capable of receiving and decoding High Definition channels over the air.
  3. Buy a High Definition TV to view the signals.

Of course, you can choose to get HDTV from multiple sources at the same time. Many people get both Satellite and OTA signals since OTA does not cost anything except the initial setup. Plus, if you are getting HDTV over satellite that may mean you already have a STB that can decode OTA signals too.

How should you get your high definition programming? It depends on your area and what is available. Many areas have exceptional OTA HD broadcasts. However, in the case of OTA signals, you will not get many channels and you will have to set up an antenna. Most people choose OTA as a second choice after getting cable or satellite as their primary TV reception method.

Only some areas are offering DTV and HDTV through the local cable companies. You can rent a STB for as low as $9.95 per month from many cable companies that offer Digital TV right now. This is a huge advantage when compared to buying a $400 to $900 STB that may be old and outdated in just a few years. However, the question remains: Does your area get DTV or HDTV through a local cable company? If not, you simply can not make this choice at this point in time.

Then, there is Satellite. You will be able to get satellite transmissions from almost anywhere. You will be guaranteed to get a lot of channels and you will not have to bother with setting up an antenna. You will have to set up a Satellite dish, which in many cases can be done for you with an installation fee.


Internet

Internet providers offer High-Def and 4K movies, TV shows, sporting events, news, comedy and more. You need a TV with Wi-Fi or Ethernet, a modem, router and Internet Service.

Optical Disc - Blu-ray

Blu-ray discs are High-Def and 4K with a variety of content including movies, TV series and more. A Blu-ray player, which also plays DVD is needed and for 4K you need a UHD Blu-ray player.
