Digital media players (DMP) are home entertainment consumer electronics devices first introduced in 2000 that can connect to a home network to stream digital media (such as digital music, digital photos, or digital video). They should not be confused with portable media players (also known as mobile media players), which are portable consumer electronics devices capable of storing and playing digital media such as audio, images, and video files. Digital media players can stream files from a personal computer and network-attached storage or from another networked media server to play back the media on a television or video projector display for home cinema. Most digital media players utilize a 10-foot user interface, and many are navigated via a remote control.
Some digital media players also have Smart TV features, such as allowing users to stream media such as digital versions of movies and TV shows from the Internet or streaming services and online media sites like YouTube, Vimeo, Netflix, Hulu, Spotify, and Amazon.com. Some other digital media players allow users to play back locally stored content from an attached USB hard disk or directly connect a Hard disk drive externally, or internally in the digital media player via a Serial ATA (SATA) port. These types of digital media player are sometimes referred to as HD Media Players or HDD Media Player if they can support a Hard Disk Drive installed inside. In the 2010s, the main difference between most "digital media players" and many modern set-top boxes (also known a set-top units) is that the set-top boxes generally contain at least one TV-tuner and are as such capable of receiving broadcasting signal (cable television, satellite television, and over-the-air television, or IPTV).
