High Definition Content
To watch HD content with an antenna, you need three things. First, you need a television that supports high definition. Otherwise, you’ll need a signal converter to downgrade the image to work on an older TV set. Second, you will need an antenna capable of picking up digital signals from the air. A cheap $10 one from Wal-Mart will do the trick, believe it or not. Just make sure it says that it supports HDTV. Finally, you will need a signal to pick up. If you could get regular TV channels before the digital switch, then you should be able to get HD channels over the air. You will need to let your TV do a channel scan to find all that is available.
I would also like to add that if you have a standard DVD player, you should consider getting an upscaling DVD player to go with your HDTV. An upscaling DVD player takes that standard 480p DVD picture and blows it up (upscales) to 1080p, which is full high definition. It makes a huge difference in image quality. If you really want the best picture, you should get a Blu-ray player or even a Sony PS3. Just remember that in order to get the supported 1080p on your HDTV, you will need an HDMI cable. Don’t pay too much for one, either. If your HDTV only supports up to 720p, I still recommend using HDMI over anything else.
Another option for HD content, besides subscribing to a high-def cable or satellite service, is to hook your HDTV up to your computer. Many modern video cards feature HDMI-out connectors, and you can even buy some that include TV tuners. Many large HDTV’s also double as computer monitors, so with the right hardware and cabling, you could turn your computer and HDTV into a tremendous multimedia powerhouse.
