ACRCP-Audio Video Control Profile in bluetooth

- Sep 14, 2019-

The full name of AVRCP is Audio Video Cortrol Profile Audio/Video Remote Control Profile. AVRCP is designed to provide standard interfaces for control tVs, Hi-fi devices, and more. This profile is used to license a single remote control device (or other device) to control all A/V devices that users can access. AVRCP defines how to control streaming media. This includes pause, stop, start replay, volume control, and other types of remote control operations.

AVRCP defines how to control streaming media. This includes pause, stop, start replay, volume control, and other types of remote control operations. AVRCP defines two roles, the controller and the target device.


The controller is usually a remote control device, while the target device is a device that the characteristics can change. In AVRCP, the controller translates the detected user action into an A/V control signal before transmitting it to a remote Bluetooth device. For A Walkman-type media player, the control device can be a headset that allows you to skip the audio track, while the target device is the actual player.


The available features of a regular infrared remote control can be implemented in this protocol. The AVRCP protocol defines the scope of application of the AV/C digital interface command set (AV/C command set, defined by the 1394 industry association), enabling simplified implementation and ease of operation. This protocol uses AV/C device mode and command format for control messages that can be transmitted via the Audio/Video Control Transfer Protocol (AVCTP).
