Designed by Samsung Electronics, the Samsung YEPP line were first released in 1999 with the aim of making the smallest music players on the market. In 2000, Creative released the 6GB hard drive based Creative NOMAD Jukebox. The name borrowed the jukebox metaphor popularised by Remote Solution, also used by Archos. Later players in the Creative NOMAD range used microdrives rather than laptop drives. In October 2000, South Korean software company Cowon Systems released their first MP3 player, the CW100, under the brand name iAUDIO. Since then the company has released many different players. In December 2000, some months after the Creative's NOMAD Jukebox, Archos released its Jukebox 6000 with a 6GB hard drive. Philips also released a player called the Rush.
The name "MP4 player" was a marketing term for inexpensive portable media players, usually from little known or generic device manufacturers. The name itself is a misnomer, since most MP4 players through 2007 were incompatible with the MPEG-4 Part 14 or the .mp4 container format. 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, despite there being no corresponding MPEG-5 standard (as of 2018[update], the current standard, still being developed, is MPEG-4).
iriver of South Korea originally made portable CD players and then started making digital audio players and portable media players from 2002. Creative also introduced the ZEN line. Both of these attained high popularity in some regions.
PMPs are capable of playing digital audio, images, and/or video. Usually, a colour liquid crystal display (LCD) or organic light-emitting diode (OLED) screen is used as a display for PMPs that have a screen. 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.e. leaves off song/video in progress similar to tape-based media).
Newer portable media players are now coming with Internet access via Wi-Fi. Examples of such devices are Android OS devices by various manufacturers, and iOS devices on Apple products like the iPhone, iPod Touch, and iPad. 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.
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. The formats supported by a particular audio player depends upon its firmware; sometimes a firmware update adds more formats. MP3 and AAC are dominant formats, and are almost universally supported.
PMPs were earlier packaged with an installation CD/DVD that inserts device drivers (and for some players, software that is capable of seamlessly transferring files between the player and the computer). 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).
Some portable media players have recently added features such as simple camera, built-in game emulation (playing Nintendo Entertainment System or other game formats from ROM images) and simple text readers and editors. Newer PMPs have been able to tell time, and even automatically adjust time according to radio reception, and some devices like the 6th-gen iPod Nano even have wristwatch bands available.
Most DAPs are powered by rechargeable batteries, some of which are not user-replaceable. They have a 3.5 mm stereo jack; music can be listened to with earbuds or headphones, or played via an external amplifier and speakers. Some devices also contain internal speakers, through which music can be listened to, although these built-in speakers are typically of very low quality.
Nearly all DAPs consists of some kind of display screen, although there are exceptions, such as the iPod Shuffle, and a set of controls with which the user can browse through the library of music contained in the device, select a track, and play it back. The display, if the unit even has one, can be anything from a simple one or two line monochrome LCD display, similar to what are found on typical pocket calculators, to large, high-resolution, full-color displays capable of displaying photographs or viewing video content on. The controls can range anywhere from the simple buttons as are found on most typical CD players, such as for skipping through tracks or stopping/starting playback to full touch-screen controls, such as that found on the iPod Touch or the Zune HD. One of the more common methods of control is some type of the scroll wheel with associated buttons. This method of control was first introduced with the Apple iPod and many other manufacturers have created variants of this control scheme for their respective devices.
Content is placed on DAPs typically through a process called "syncing", by connecting the device to a personal computer, typically via USB, and running any special software that is often provided with the DAP on a CD-ROM included with the device, or downloaded from the manufacturer's website. Some devices simply appear as an additional disk drive on the host computer, to which music files are simply copied like any other type of file. Other devices, most notably the Apple iPod or Microsoft Zune, requires the use of special management software, such as iTunes or Zune Software, respectively. The music, or other content such as TV episodes or movies, is added to the software to create a "library". The library is then "synced" to the DAP via the software. The software typically provides options for managing situations when the library is too large to fit on the device being synced to. Such options include allowing manual syncing, in that the user can manually "drag-n-drop" the desired tracks to the device, or allow for the creation of playlists. In addition to the USB connection, some of the more advanced units are now starting to allow syncing through a wireless connection, such as via Wi-Fi or Bluetooth.
Content can also be obtained and placed on some DAPs, such as the iPod Touch or Zune HD by allowing access to a "store" or "marketplace", most notably the iTunes Store or Zune Marketplace, from which content, such as music and video, and even games, can be purchased and downloaded directly to the device.
According to the Scientific Committee on Emerging and Newly Identified Health Risks, the risk of hearing damage from digital audio players depends on both sound level and listening time. The listening habits of most users are unlikely to cause hearing loss, but some people are putting their hearing at risk, because they set the volume control very high or listen to music at high levels for many hours per day. Such listening habits may result in temporary or permanent hearing loss, tinnitus, and difficulties understanding speech in noisy environments.The World Health Organization warns that increasing use of headphones and earphones puts 1.1 billion teenagers and young adults at risk of hearing loss due to unsafe use of personal audio devices. Many smartphones and personal media players are sold with earphones that do a poor job of blocking ambient noise, leading some users to turn up the volume to the maximum level to drown out street noise. People listening to their media players on crowded commutes sometimes play music at high volumes feel a sense of separation, freedom and escape from their surroundings.
If you edit or work with video for work or for pleasure, you have likely come across a situation where you are looking for a high-quality video player to view videos. It can be difficult to search for the best MP4 player for Windows 10 or another OS due to the vast amount of players available on the internet. Often, you will then settle for one player, but there will still be some uncertainty about whether you are using the best media player software for you. 041b061a72
