HDTV tuners will not only show movies and DVD's at high definition, but will improve the viewing of normal TV.
It is because of the improved definition or color and picture quality of DVD's and programs that make HDTV tuners very popular with viewers.
Television sets often come with HDTV tuners already built into them, these are called integrated HDTV's.
If you are considering buying an external high definition TV tuner for your television, make sure that your TV set is HDTV compatible.
A separate tuner may also be needed.
This can be either a cable or satellite box for watching high definition programs.
Most people have heard that there is a mandate on televisions to make integrated HDTVs.
This is not entirely correct.
Certain televisions that are for sale after a certain date will be required to have built in tuners.
The tuners required won't be HDTV.
The mandate is actually referring to ATSC tuners.
It is not even necessary that TV's be able to display HDTV resolutions without either an internal or external tuner.
This new mandate will not apply to plasma and front projectors.
The mandate will not take effect for some time.
Until then there will be no change in television manufacture or tuners.
It is important to ask about features of high definition TV tuners before making a choice.
If you are not sure what some of the features are, ask for clarification.
Make sure that your television is compatible, HDTV tuners may not work with older televisions.
Ask your cable or satellite company weather they support high definition TV, as many people find out later down the road that they cannot receive HDTV programs through cable or satellite.
Ask about what kind of warranties are available and what parts they actually cover before buying.
External high definition TV tuners are quite reasonably priced.
Prices start at around $150.
If you are on a budget, make sure not to buy cheaply made appliances.
Always wait for specials or price reductions on reliable brands.
One of the most popular brands available is the Samsung SIR-T451.
This one is ideal for high definition programming on any high definition TV compatible television.
There are many more HDTV tuners available on the market.
By doing a quick search on your favorite search engine, you will be able to find a HDTV tuner that will fit both your budget and your TV's requirements.
