What is a Bluetooth 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. The EGO Cup FM, EGO Talk, EGO Flash and EGO Look are using AVRCP to control the connected Bluetooth device. The available functions via Bluetooth Audio/Video Remote Control Profile are: Play, Stop, Pause, Forward and Backward.
