• Answer:

  Control all your media from one PC. Combine all media into one system: television, games, movies, music can all be watched and stored in one place. A Media Center PC or Home Theater PC, or HTPC for short, is a personal computer connected to a television. It is often used as a digital photo, music, and video player, or as a Computer and video games device. Adding a TV tuner card allows an HTPC to record television as well.
