(Home Theater PC) A PC that is used to play and store music and movies. HTPCs are connected to their own high-quality stereo system or to a home theater system. A major advantage of an HTPC is being able to copy CDs and DVDs to the hard disk and use the computer as a jukebox. With the addition of software, a regular PC can be turned into an HTPC, and its CD/DVD drives provide an economical alternative to many stand-alone CD/DVD players that might be purchased for a home theater. Windows XP Media Center is an HTPC. See digital media server and home theater.
