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.

History

In 2002, Archos first widely sold a portable media player, the Archos Jukebox Multimedia. Manufacturers have since implemented abilities to view images and play videos into their devices.

In 2004, Microsoft attempted to take advantage of the growing PMP market by launching the Portable Media Center (PMC) platform. It was introduced at the 2004 Consumer Electronics Show with the announcement of the Zen Portable Media Center, which was co-developed by Creative. The Microsoft Zune series would later be based on the Gigabeat S, one of the PMC-implemented players.

Typical features

• 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 that are included with the players may be able to convert video files into a compatible format.

Syncing and transferring

PMPs are usually 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 recent players, however, these are usually available online via the manufacturers' websites, or natively recognized by the operating system through Universal Mass Storage (UMS) or Media Transfer Protocol (MTP).
