(Home Theater PC) A personal computer that is used to store and play music and movies as well as display photos. Also called a "living room PC," an HTPC is installed in the A/V cabinet and connects to a stereo or home theater system. The HTPC's CD/DVD drive is used to play the media or rip titles to the hard drive.With media player software, a quality sound card and quiet case, a standard PC can be turned into an HTPC. For example, the Media Center interface in Windows provides the so-called "10-foot user interface" for HTPC deployment. An HTPC's CD/DVD drive often provides an economical alternative to stand-alone CD/DVD decks and digital media servers designed strictly for home theaters. However, high-end HTPCs can be significantly more costly than regular PCs. See digital media server, Windows Media Center, 10-foot user interface and home theater.
