What is HD Television?

Posted March 21, 2013 by Desert Valley Audio Video


HD (high definition) is a hot topic among home entertainment enthusiasts across the world. Within the past several years, HD television has moved closer to becoming the home standard for those who enjoy gaming, watching shows, and movies. Most people get the idea that HD offers superior image quality, but how does it work?

HD Explained

HD television works through the transmission of a compressed digital signal from a source such as your gaming system, blu ray player, or digital cable box. The digital signal is decompressed within the device as a 1080 interlaced megapixel signal to send the information to your television. Your television goes through the process of upscaling the image to fit its resolution and the data is displayed with a high image refresh rate to allow the frame rate to transition smoothly and provide a clear image.

  • An image is not considered HD (high definition) by modern standards if it isn’t transmitted as a 1080p resolution.
  • Some LCD television’s don’t offer true HD because of their limited screen resolution and refresh rate such as 720p.

It is always a great idea to do careful research about the new HD systems that you are considering buying. It is also important to make a point of asking questions about the products from a knowledgeable sales associate so you can make an informed decision when you want to buy a true HD system.
