Setting up a television used to be easy. A person only had to plug it in, turn it on, adjust the antenna, and find a station to watch. Now, televisions require a little more effort to get going. Many come with over eight different input/output types. Throw in a DVD player, VCR, video game console and external receiver, the thought of setting up a television and all of its components can be confusing if not frustrating. However, by understanding how video and audio signals travel, connecting any device to a television isn’t as difficult as it may seem.
