Digital media players (DMP) are home entertainment consumer electronics devices that can connect to a home network to stream digital media (such as music, pictures, or video), and are not to be confused with portable media players (also known as mobile media player). Digital media players as devices can stream files from a personal computer and network-attached storage or other networked media server to playback the media outputted to 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.〔http://gizmodo.com/5827779/roku-2-same-old-same-old Roku 2: Same Old (But Still Good), Same Old〕〔http://www.dlna.org/dlna-for-industry/digital-living/how-it-works/dlna-device-classes/digital-media-player Digital Media Player - DLNA Device Classes〕 Some digital media players also have Smart TV features, like allowing users to stream media from the internet or streaming services and online media sites like YouTube, Vimeo, Netflix, Hulu, Spotify, and Amazon.com. Some other digital media players also allow users to playback locally stored content from a direct attached USB hard disk or even direct connect a Hard disk drive externally, or even internally in the digital media player via a Serial ATA (SATA) port, therefore these types of digital media player are sometimes referred to as HD Media Player or HDD Media Player if they can support to have a Hard Disk Drive installed inside. Digital media players are also commonly referred to as a digital media extender, digital media streamer, digital media hub, digital media adapter, or digital media receiver (which should not be confused with ''AV Receiver'' that are also called ''Digital Media Renderer'').〔https://us.en.kb.sony.com/app/answers/detail/a_id/35234 What are the differences in DLNA device classes?〕〔http://hometheater.about.com/od/interactivetelevision/a/Dlna-Certifications-The-Role-Of-Each-Network-Media-Component-In-Media-Sharing.htm DLNA Certifications - The Role of Each Network Media Component in Media Sharing〕 Today the main difference between most modern "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). ==Overview== Digital media players fills a specific market niche, and with the popularity of both mobile digital media players, digital cameras, fast internet download speeds, and cheap mass storage, many people now have large collections of digital media files that cannot be played on a conventional analog HiFi without connecting a computer to a television, so the means to playback these files on a network connected digital media player that is permanently connected to a television and control it with a remote is seen as a convenience. Most digital media players are usually designed for compactness and affordability, and tend to have small or non-existent hardware displays other that simple lights as indication if the device is powered on or off. Interface navigation on the television is usually performed with an infrared remote control, while more advanced digital media players come with high performance remote controls which allow intuitive control of the interface using touch sensors on them, and some remotes also include accelerometers for air mouse features which allow basic motion gaming. These digital media player devices are not usually able to play physical CD, DVD-Video, or Blu-ray Disc media directly, and instead require a user to convert these media into playable files using a separate computer and software. They are also not usually capable of recording audio or video. Also the rapid growth in the availability of online content, including music and video and games has also made it easier for consumers use these networked devices. YouTube, for instance, is a common plug-in available on most networked devices. Netflix has also struck deals with many consumer electronics makers to have their interface available for their streaming subscribers. This symbiotic relationship between Netflix and consumer electronics makers has helped propel Netflix to become the largest subscription video service in the U.S., using up to 20% of U.S. bandwidth at peak times. It is also common to find digital media player functionality integrated in other consumer-electronic appliances today, such as DVD players, set-top boxes, or even Smart TVs, and nowadays also in video game consoles, such as the Nintendo Wii, Sony PlayStation 3 and the Microsoft Xbox 360 support media management beyond their original gaming orientation. All these are however not in-scope for this article because their primary functions are either to play video games or to watch broadcast television, and their features to play or stream locally stored content, if they have any, are only secondary features. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「digital media player」の詳細全文を読む スポンサード リンク
