Audio/Video, Remote Control Profile. AVRCP is a profile that has been defined and adopted by the Bluetooth Special Interest Group (Bluetooth SIG) to provide a standard interface to control various equipment via a single device.

Taken from Wikipedia:

[AVRCP is a profile] defined and adopted by the Bluetooth SIG:

Audio/Video Remote Control Profile (AVRCP)

This profile is designed to provide a standard interface to control TVs, Hi-fi equipment, etc. to allow a single remote control (or other device) to control all of the A/V equipment to which a user has access. It may be used in concert with A2DP or VDP.

It has the possibility for vendor-dependent extensions.

AVRCP has several versions with significantly increasing functionality:

  • 1.0—Basic remote control commands (play/pause/stop, etc.)
  • 1.3—all of 1.0 plus metadata and media-player state support
    • The status of the music source (playing, stopped, etc.)
    • Metadata information on the track itself (artist, track name, etc.).
  • 1.4—all of 1.0, 1.3, plus media browsing capabilities for multiple media players
    • Browsing and manipulation of multiple players
    • Browsing of media metadata per media player, including a "Now Playing" list
    • Basic search capabilities
