Standardization Proposal for “Automotive-Grade AVRCP” with Respect to In-Car use of Bluetooth Devices.
With regard to the use of portable consumer electronic devices in an automobile, Bluetooth has become a widely accepted method for short range wireless communication between a vehicle and a portable device. One Bluetooth connectivity protocol for this use case is Audio/Visual Remote Control Profile (AVRCP). Currently, AVRCP specifies mandatory commands for both target devices (cellular phones and audio players), as well as for control devices like an audio head unit. However, there is no requirement that control devices and target devices implement the same commands, nor is there a requirement that supported commands utilize information that would be useful in improving the driver's experience (i.e. metadata). This paper will describe the impact of this reality from the perspective of the automotive consumer, and propose an “automotive grade” AVRCP that could provide a more consistent consumer experience in the automotive market.
