The "Roku XD/S digital media players works with popular streaming media sites like "Amazon.com and "Netflix as well as locally stored content

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 music, photos or digital video.[1][2] Digital media players can stream files from a "personal computer, "network-attached storage or another networked "media server, to play 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.[3][4] 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.[5] In the 2010s, the main difference between most digital media players and modern "set-top boxes was the obligation to have a "TV tuner. Set-top boxes generally contain at least one TV tuner and are as such capable of receiving "broadcasting "signals from "cable television, "satellite television, "over-the-air television or "IPTV.

Overview[edit]

In the 2010s, with the popularity of "portable media players and "digital cameras, as well as fast Internet download speeds and relatively cheap mass storage, many people came into possession of large collections of digital media files that cannot be played on a conventional analog "HiFi without connecting a computer to an amplifier or television. The means to play these files on a network-connected digital media player that is permanently connected to a television is seen as a convenience. The rapid growth in the availability of online content has made it easier for consumers to use these devices and obtain content. "YouTube, for instance, is a common plug-in available on most networked devices. "Netflix has also struck deals with many consumer-electronics makers to make their interface available in the device's menus, 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.,[6] using up to 20% of U.S. bandwidth at peak times.[7]

Media players are often designed for compactness and affordability, and tend to have small or non-existent hardware displays other than simple "LED lights to indicate whether the device is powered on. Interface navigation on the television is usually done with an "infrared "remote control, while more-advanced digital media players come with high-performance "remote controls which allow control of the interface using integrated touch sensors. Some remotes also include "accelerometers for air mouse features which allow basic motion gaming. Most digital media player devices are unable to play physical audio or video media directly, and instead require a user to convert these media into playable digital files using a separate computer and software. They are also usually incapable of recording audio or video. In the 2010s, it is also common to find digital media player functionality integrated into other consumer-electronics appliances, such as "DVD players, "set-top boxes, "Smart TVs, or even "video game consoles, although these devices are beyond the scope of this article.

Terminology[edit]

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).[8][9]

Digital media player manufacturers use a variety of names to describe their devices. Some more commonly used alternative names include:

Functionality and capability[edit]

A digital media player can connect to the home network using either a wireless (IEEE 802.11a, b, g, and n) or wired "Ethernet connection. Digital media players includes a user interface that allows users to navigate through their digital media library, search for, and play back media files. Some digital media players only handle music; some handle music and pictures; some handle music, pictures, and video; while others go further to allow internet browsing or controlling Live TV from a PC with a TV tuner.

Some other capabilities which are accomplished by digital media players include:

Hardware[edit]

In the 2010s, there are stand-alone digital media players on the market from AC Ryan, Asus, Apple (e.g., "Apple TV[14]), NetGear (e.g., NTV and NeoTV models), Dune, iOmega, Logitech, Pivos Group, Micca, Sybas (Popcorn Hour), "Amkette EvoTV,[15] D-Link, EZfetch, "Android TV,[16] Pinnacle, "Xtreamer, and "Roku,[17] just to name a few. The models change frequently, so it is advisable to visit their web sites for current model names.

These devices come with low power consumption processors or "SoC (System on Chip) and are most commonly either based on "MIPS or "ARM architecture[18] processors combined with integrated "DSP "GPU in a "SoC (or "MPSoC) package. They also include "RAM-memory and some type of built-in "type of non-volatile computer memory (Flash memory).[13]

Operating system[edit]

While most media players have traditionally been running "proprietary or "open source "software frameworks versions based "Linux as their operating systems, many newer network connected media players are based on the "Android platform which gives them an advantage in terms of applications and games from the "Google Play store. Even without Android some digital media players still have the ability to run applications (sometimes available via an 'app store' "digital distribution "platform), interactive on-demand media, personalized communications, and social networking features[19][20][21][22][23]

Internal harddrive capabilities[edit]

HD media player or HDD media player (HDMP) is a generic term used for a category of consumer product that combines digital media player with a "hard drive (HD) "enclosure with all the hardware and software for playing "audio, "video and photos to a television. All these can play computer-based media files to a television without the need for a separate computer or network connection, and some can even be used as a conventional external hard drive. These types of digital media players are sometimes sold as empty shells to allow the user to fit their own choice of hard drive (some can manage unlimited hard disk capacity and other only a certain capacity, i.e. 1TB, 2TB, 3TB, or 4TB), and the same model is sometimes sold with or without an internal hard drive already fitted.

Common connection ports[edit]

Television connection is usually done via; composite, "SCART, Component, "HDMI video, with Optical Audio (TOSLINK/SPDIF), and connect to the local network and "broadband internet using either a wired "Ethernet or a wireless "wifi connection, and some also have built-in "Bluetooth support for remotes and game-pads or joysticks. Some players come with "USB ("USB 2.0 or "USB 3.0) ports which allow local media content playback.

Streaming and communication protocols[edit]

While early digital media players used proprietary communication protocols to interface with media servers, today most digital media players either use standard-based protocols such "SMB/CIFS/SAMBA or "NFS, or rely on some version of "UPnP (Universal Plug and Play) and "DLNA (Digital Living Network Alliance) standards. DLNA-compliant digital media players and Media Servers is meant to guarantee a minimum set of functionality and proper interoperability among digital media players and servers regardless of the manufacturer, but unfortunately not every manufacturer follows the standards perfectly which can lead to incompatibility.

Formats, resolutions and file systems[edit]

Digital media players can usually play "H.264 (SD and "HD), "MPEG-4 Part 2 (SD and HD), "MPEG-1, "MPEG-2 ".mpg, "MPEG-2 ."TS, "VOB and "ISO images video, with "PCM, "MP3 and "AC3 audio tracks. They can also display images (such as "JPEG and "PNG) and play music files (such as "FLAC, "MP3 and "Ogg).

Media server software[edit]

Some digital media players will only connect to specific media server software installed on a PC to stream music, pictures and recorded or live TV originating from the computer. Apple iTunes can, for example, be used this way with the Apple TV hardware that connects to a TV. Apple has developed a tightly integrated device and content management ecosystem with their "iTunes Store, personal computers, "iOS "devices, and the "AppleTV "digital media receiver.[24] The most recent version of the AppleTV, at $99, has lost the hard-drive that was included in its predecessor and fully depends on either streaming internet content, or another computer on the home network for media.[25]

History[edit]

By November 2000, an audio-only digital media player was demonstrated by a company called SimpleDevices,[26] which was awarded two patents covering this invention in 2006.[27][28] Developed under the SimpleFi name by "Motorola in late 2001, the design was based on a Cirrus Arm-7 processor and the wireless "HomeRF networking standard which pre-dated 802.11b in the residential markets.[29] Other early market entrants in 2001 included the "Turtle Beach AudioTron, "Rio Receiver and "SliMP3 digital media players. An early version of a video-capable digital media player was presented by F.C. Jeng et al. in the International Conf. on Consumer Electronics in 2002.[30] It included a network interface card, a media processor for audio and video decoding, an analog video encoder (for video playback to a TV), an audio digital to analog converter for audio playback, and an IR (infrared receiver) for remote-control-interface.

A concept of a digital media player was also introduced by Intel in 2002 at the "Intel Developer Forum as part of their “Extended Wireless PC Initiative." Intel’s digital media player was based on an Xscale PXA210 processor and supported 802.11b wireless networking. Intel was among the first to use the Linux embedded operating system and "UPnP technology for its digital media player. Networked audio and DVD players were among the first consumer devices to integrate digital media player functionality. Examples include the Philips "Streamium-range of products that allowed for remote streaming of audio, the GoVideo D2730 Networked DVD player which integrated DVD playback with the capability to stream Rhapsody audio from a PC, and the Buffalo LinkTheater which combined a DVD player with a digital media player. More recently, the Xbox 360 gaming console from Microsoft was among the first gaming devices that integrated a digital media player. With the Xbox 360, Microsoft also introduced the concept of a "Windows Media Center Extender, which allows users to access the Media center capabilities of a PC remotely, through a home network. More recently, Linksys, D-Link, and HP introduced the latest generation of digital media players that support 720p and 1080p high resolution video playback and may integrate both Windows Extender and traditional digital media player functionality.

Connections[edit]

There are two ways to connect an extender to its central "media center or "HTPC server - wired, or wireless.

Wireless[edit]

A wireless connection can be established between the media extender and its central media center. On the downside, interference may cause a "less than optimal" connection and cause network congestion, resulting in stuttering sound, missing frames from video, and other anomalies. It is recommended["by whom?] that an "802.11a or better be used, and over as short of a distance as possible.

Market impact on traditional television services[edit]

The convergence of content, technology, and broadband access allows consumers to stream television shows and movies to their high-definition television in competition with "pay television providers. The research company SNL Kagan expects 12 million households, roughly 10%, to go without cable, satellite or telco video service by 2015 using "Over The Top services.[32] This represents a new trend in the broadcast television industry, as the list of options for watching movies and TV over the Internet grows at a rapid pace. Research also shows that even as traditional television service providers are trimming their customer base, they are adding "Broadband Internet customers. Nearly 76.6 million U.S. households get broadband from leading cable and telephone companies,[33] although only a portion have sufficient speeds to support quality video steaming.[34] Convergence devices for home entertainment will likely play a much larger role in the future of broadcast television, effectively shifting traditional revenue streams while providing consumers with more options.[34]

According to a report from the researcher NPD In-Stat, only about 12 million U.S. households have their either Web-capable TVs or digital media players connected to the Internet, although In-Stat estimates about 25 million U.S. TV households own a set with the built-in network capability. Also, In-Stat predicts that 100 million homes in North America and western Europe will own digital media players and television sets that blend traditional programs with Internet content by 2016.[35]

Use for illegal streaming[edit]

Since at least 2015,[36][37][38][39] dealers have marketed digital media players, often running the Android operating system and branded as being "fully-loaded", that are promoted as offering free streaming access to copyrighted media content, including films and television programs, as well as "live feeds of television channels. These players are commonly bundled with the open source media player software "Kodi, which is in turn pre-loaded with "plug-ins enabling access to services streaming this content without the permission of their respective copyright holders. These "fully-loaded" set-top boxes are often sold through online marketplaces such as "Amazon.com and "eBay, as well as websites and local retailers.[40][41] The spread of these players has been attributed to their ease of use (with user experiences similar to legal subscription services such as "Netflix) and low cost, as well as the content that is offered from the services pre-installed on the boxes.[41][42][40]

"Fully-loaded" set-top boxes have been subject to legal controversies, especially noting that their user experiences made them accessible to end-users who may not always realize that they are actually streaming pirated content.[41][42] In the United Kingdom, the "Federation Against Copyright Theft (FACT) has taken court actions on behalf of rightsholders against those who market digital media players pre-loaded with access to copyrighted content. In January 2017, an individual seller plead not guilty to charges of marketing and distributing devices that "circumvent "technological protection measures.[43][44][45] In March 2017, the "High Court of Justice ruled that "BT Group, "Sky plc, "TalkTalk, and "Virgin Media must block servers that had been used on such set-top boxes to illegally stream "Premier League football games.[46] Later in the month, "Amazon UK banned the sale of "certain media players" that had been pre-loaded with software to illegally stream copyrighted content.[47] On 26 April 2017, the "European Court of Justice ruled that the distribution of set-top boxes with access to unauthorized streams of copyrighted works violated the exclusive rights to communicate them to the public.[41] In September 2017, a British seller of such boxes pled guilty to violations of the "Copyright, Designs and Patents Act for selling devices that can circumvent effective "technical protection measures.[48]

In Canada, it was initially believed that these set-top boxes fell within a legal grey area, as the transient nature of streaming content did not necessarily mean that the content was being downloaded in violation of "Canadian copyright law.[40] However, on 1 June 2016, a consortium of Canadian media companies ("BCE Inc., "Rogers Communications, and "Videotron) obtained a temporary federal injunction against five retailers of Android-based set-top boxes, alleging that their continued sale were causing "irreparable harm" to their television businesses, and that the devices' primary purpose were to facilitate copyright infringement. The court rejected an argument by one of the defendants, who stated that they were only marketing a hardware device with publicly-avaliable software, ruling that the defendants were "deliberately encourag[ing] consumers and potential clients to circumvent authorized ways of accessing content."[49][49] 11 additional defendants were subsequently added to the suit. The lawyer of one of the defendants argued that retailers should not be responsible for the actions of their users, citing that the devices, as well as other tablets and computers, can be used for legal or illegal purposes.[50] In April 2017, the "Federal Court of Appeal blocked an appeal requesting that the injunction be lifted pending the outcome of the case.[51]

Although the software is free to use, the developers of Kodi have not endorsed any add-on or Kodi-powered device intended for facilitating copyright infringement. Nathan Betzen, president of the XBMC Foundation (the non-profit organization which oversees the development of the Kodi software), argued that the reputation of Kodi had been harmed by third-party retailers who "make a quick buck modifying Kodi, installing broken piracy add-ons, advertising that Kodi lets you watch free movies and TV, and then vanishing when the user buys the box and finds out that the add-on they were sold on was a crummy, constantly breaking mess." Betzen stated that the XBMC Foundation was willing to enforce its "trademarks against those who use them to promote Kodi-based products which facilitate copyright infringement.[52][36]

Following a lawsuit by "Dish Network against TVAddons, a website that offered streaming add-ons often used with Kodi and on such devices, in June 2017, the group shut down its add-ons and website, seemingly in response to the suit. A technology analyst speculated that the service could eventually re-appear under a different name in the future, as have "torrent trackers.[53] In June, the service's operator was also sued by the Bell/Rogers/Videotron consortium for inducing copyright infringement.[54]

In June 2017, "Televisa was granted a court order banning the sale of all "Roku products in Mexico, as it was alleged that third-parties had been operating subscription television services for the devices that contain unlicensed content. The content is streamed through unofficial apps that are added to the devices through hacking. Roku objected to the allegations, stating that these services were not certified by the company or part of its official Channels platform, whose terms of service require that they have rights to stream the content that they offer. Roku also stated that it actively cooperates with reports of channels that infringe copyrights.[55]
