A portable multimedia player (PMP), sometimes referred to as a portable video player (PVP), is a consumer electronics device that is capable of storing and playing digital media. Digital audio players (DAP) that can also display images and play videos are PMPs.
Like DAPs, the data is typically stored on a hard drive, microdrive, or flash memory. Other types of electronic devices like cellphones are sometimes referred as PMPs because of their playback capabilities.
PMPs are capable of playing digital audio, images, and video. Usually, a color LCD or OLED screen is used as a display. 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 organizer are emulated, or support for games, like the iriver clix (through compatibility of Adobe Flash Lite) or the PlayStation Portable, is included.
Audio Playback
Nearly all players are compatible with the MP3 audio format, and many others support Windows Media Audio (WMA), Advanced Audio Coding (AAC) and WAV. Audio files purchased from online stores or ripped from CDs may include DRM copy protection, which most modern players support.
Some players are compatible with open-source formats like Ogg Vorbis and the Free Lossless Audio Codec (FLAC). Every device has a bitrate limit on each compatible format.
Image Viewing
The JPEG format is compatible on all players that are capable of displaying images. Some players, like the iPod series, provide compatibility to additional file formats like GIF, PNG, and TIFF, while others are bundled with conversion software.
Video Playback
Most newer players support the MPEG-4 video format, and many other players are compatible with Windows Media Video (WMV) and the defunct AVI, now mostly used as a container format. Recently, more and more players are enabling compatibility to the DivX video format and its open-source parallel, Xvid. Software included with the players may be able to convert video files into a compatible format.
