A portable media player PMP also including the related digital audio player DAP is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files.

In contrast, analogue portable audio players play music from non-digital media that use analogue signal storage, such as cassette tapes or vinyl records. Digital audio players DAP were in the past often marketed and sold as " MP3 players ", even if they also support other file formats and media types.

Generally speaking, they are portable, employing internal or replaceable batteries , equipped with a 3. Some players also include FM radio tuners , voice recording and other features.

MP3-playing devices were mostly pioneered by South Korean startups, who by would control the majority of global sales. The immediate predecessor in the market place of the digital audio player was the portable CD player and prior to that, the personal stereo. In particular, Sony 's Walkman and Discman are the ancestors of digital audio players such as Apple 's iPod. Plans were made for a minute stereo memory card and the system was at one time fitted with a hard drive which would have enabled over an hour of recorded digital music.

Later Kramer set up a company to promote the IXI and five working prototypes were produced with bit sampling at It could store up to an hour of music, but despite getting an award at CES only 25 copies were made. It only supported playback of digital audio in Audible's proprietary, low-bitrate format which was developed for spoken word recordings.

Capacity was limited to 4 MB of internal flash memory, or about 2 hours of play, using a custom rechargeable battery pack. The unit had no display and rudimentary controls. MP3 was introduced as an audio coding standard in It was based on several audio data compression techniques, including the modified discrete cosine transform MDCT , FFT and psychoacoustic methods.

MP3 became a popular standard format and as a result most digital audio players after this supported it and hence were often called " MP3 players ". Noticeably, major technology companies did not catch on with the new technology, and instead young startups would come to dominate the early era of MP3 players.

It was a success during the holiday season, with sales exceeding expectations. Universal City Studios and MP3 players were ruled legal devices. Eiger Labs and Diamond went on to establish a new segment in the portable audio player market and the following year saw several new manufacturers enter this market.

The player would be the start of the Rio line of players. They also used slower parallel port connections to transfer files from PC to player, necessary as most PCs then used the Windows 95 and NT operating systems, which did not have native support for USB connections. As more users migrated to Windows 98 by , most players transitioned to USB. In the first hard drive based DAP using a 2. Also at the end of the first in-dash MP3 player appeared. For the next couple of years, there were particularly much output from South Korean companies, namely the startups iRiver brand of Reigncom , Mpio brand of DigitalWay and Cowon.

The company's first MP3-supporting Walkman player did not come until Designed by Samsung Electronics , the Samsung YEPP line were first released in with the aim of making the smallest music players on the market.

The name borrowed the jukebox metaphor popularised by Remote Solution , also used by Archos. Since then the company has released many different players. Philips also released a player called the Rush. Many MP3 players can encode directly to MP3 or other digital audio format directly from a line in audio signal radio, voice, etc.

Devices such as CD players can be connected to the MP3 player using the USB port in order to directly play music from the memory of the player without the use of a computer. They can be independently obtained and upgradable one can change the head or the body; i. With the development of a spartan user interface and a smaller form factor, the iPod was initially popular within the Macintosh community.

In July , Apple introduced the second generation update to the iPod, which was compatible with Windows computers through Musicmatch Jukebox. Manufacturers have since implemented abilities to view images and play videos into their devices.

The next year, Archos released another multimedia jukebox , the AV , with a 3. In the same year, Toshiba released the first Gigabeat.

In , Dell launched a line of portable digital music players called Dell DJ. They were discontinued by The name "MP4 player" was a marketing term for inexpensive portable media players, usually from little known or generic device manufacturers. Instead, the term refers to their ability to play more file types than just MP3. In this sense, in some markets like Brazil, any new function added to a given media player is followed by an increase in the number, for example an MP5 or MP12 Player, [50] despite there being no corresponding MPEG-5 standard as of [update] , the current standard, still being developed, is MPEG Creative also introduced the ZEN line.

Both of these attained high popularity in some regions. It was introduced at the Consumer Electronics Show with the announcement of the Zen Portable Media Center , [51] which was co-developed by Creative. In May , flash memory maker SanDisk entered the PMP market with the Sansa line of players, starting with the e series, and then following up with the m series, and c series.

In , Apple introduced the iPod Touch , the first iPod with a multi-touch screen. Some similar products existed before such as the iriver clix in In South Korea, sales of MP3 players peaked in , but started declining afterwards. This was driven partly by the launch of mobile television services DMB , which along with increased demand of movies on the go led to a transition away from music-only players to PMPs.

European buying patterns differed; while Apple was in a particularly strong position in the United Kingdom, continental Western Europe generally preferred cheaper, often Chinese rebranded players under local brands such as Grundig. Creative was the top selling maker in its home country of Singapore. The innovation spread rapidly across the globe and by , more than half of all music sold in South Korea was sold directly to mobile phones and all major handset makers in the world had released MP3 playing phones.

By , more MP3 playing mobile phones were sold than all stand-alone MP3 players put together. The rapid rise of the media player in phones was quoted by Apple as a primary reason for developing the iPhone. In , the number of phones that could play media was over 1 billion.

Mobile phones with PMP functionalities such as video playback also started appearing in the s. DAPs and PMPs have declined in popularity after the late s due to increasing worldwide adoption of smartphones that already come with PMP functionalities. In the EU , demand for MP3 players peaked in with Both sales and revenue experienced a double-digit shrinkage for the first time in Meanwhile, sales of the best selling product, the iPod, was eclipsed by the company's iPhone smartphone by Various players include the ability to record video, usually with the aid of optional accessories or cables, and audio, with a built-in microphone or from a line out cable or FM tuner.

Some players include readers for memory cards , which are advertised to equip players with extra storage or transferring media. In some players, features of a personal organiser are emulated, or support for video games , like the iriver clix through compatibility of Adobe Flash Lite or the PlayStation Portable , is included. Only mid-range to high-end players support "savestating" for power-off i. Audio files purchased from online stores may include digital rights management DRM copy protection, which many modern players support.

The JPEG format is widely supported by players. Software included with the players may be able to convert video files into a compatible format. Many players have a built-in electret microphone which allows recording. Usually recording quality is poor, suitable for speech but not music. There are also professional-quality recorders suitable for high-quality music recording with external microphones, at prices starting at a few hundred dollars.

Many also have an option to change the band from the usual DAPs typically never have an AM band, or even HD Radio since such features would be either cost-prohibitive for the application, or because of AM's sensitivity to interference. Newer portable media players are now coming with Internet access via Wi-Fi. Internet access has even enabled people to use the Internet as an underlying communications layer for their choice of music for automated music randomisation services like Pandora , to on-demand video access which also has music available such as YouTube.

This technology has enabled casual and hobbyist DJs to cue their tracks from a smaller package from an Internet connection, sometimes they will use two identical devices on a crossfade mixer. Many such devices also tend to be smartphones.

Many mobile digital media players have last position memory , in which when it is powered off, a user doesn't have to worry about starting at the first track again, or even hearing repeats of others songs when a playlist, album, or whole library is cued for shuffle play , in which shuffle play is a common feature, too. Early playback devices to even remotely have "last position memory" that predated solid-state digital media playback devices were tape-based media, except this kind suffered from having to be "rewound", whereas disc-based media suffered from no native "last position memory", unless disc-players had their own last position memory.

However, some models of solid-state flash memory or hard drive ones with some moving parts are somewhat the "best of both worlds" in the market. Media players' firmware may be equipped with a basic file manager and a text reader.

There are also royalty free lossy formats like Vorbis for general music and Speex and Opus used for voice recordings. When "ripping" music from CDs, many people recommend the use of lossless audio formats to preserve the CD quality in audio files on a desktop, and to transcode the music to lossy compression formats when they are copied to a portable player. MP3 and AAC are dominant formats, [67] and are almost universally supported. For later players, however, these are usually available online via the manufacturers' websites, or increasingly natively recognised by the operating system through Universal Mass Storage UMS or Media Transfer Protocol MTP.

They are used to directly transfer content from external devices, and expand the storage capacity of PMPs. A standard PMP uses a 5-way D-pad to navigate. Many alternatives have been used, most notably the wheel and touch mechanisms seen on players from the iPod and Sansa series. Another popular mechanism is the swipe-pad, or 'squircle', first seen on the Zune. Additional buttons are commonly seen for features such as volume control.

Sizes range all the way up to 7 inches 18 cm. Resolutions also vary, going up to WVGA. Most screens come with a colour depth of bit, but higher quality video-oriented devices may range all the way to bit, otherwise known as true colour , with the ability to display Screens commonly have a matte finish but may also come in glossy to increase colour intensity and contrast. More and more devices are now also coming with touch screen as a form of primary or alternate input.

Certain devices, on the other hand, have no screen whatsoever, reducing costs at the expense of ease of browsing through the media library.
