AVRC is a Bluetooth profile that allows remote control of media playback on other devices. Supported functions are play, pause, stop, next, and previous.
It is usually coupled with A2DP so that, for example, wireless headphones use A2DP to stream the music and AVRC to control playback.
AVRCP is designed to provide a standard interface for controlling TV, Hi-fi devices, and more. This profile is used to permit a single remote control device (or other device) to control the A/V devices that all users can access. AVRCP defines how to control the characteristics of streaming media.
