Process of audio data exchanges of information between a central unit and a bluetooth controller

摘要

Electronic device comprising audio/video functionalities including: —a central processing unit (100) comprising means of storage of audio/video files; —a Bluetooth communication controller (200) allowing the wireless communication of audio/video files towards a satellite (20), said communication controller comprising a buffer (210) ensuring the provisional storage of audio/video data received by the central processing unit; characterized in that it comprises —means for transmitting a packets burst of audio/video data towards said communication controller; —means for ensuring an intermittent deactivation of said central processing unit between two bursts of audio packets in order to reduce the electricity consumption of said central processing unit.

1. An electronic device comprising audio/video functionalities, comprising:
a central processing unit comprising a first memory adapted to store audio/video files; a Bluetooth communication controller adapted to communicate with a satellite via a wireless communication according to a Bluetooth protocol, said Bluetooth communication controller comprising a second memory adapted to store audio/video data; wherein: said central processing unit generate a HCI type command transmitted to said Bluetooth communication controller, which HCI type command defines a threshold value used for monitoring a level of filling of said second memory; said Bluetooth communication controller answers to said HCI type command by a command specifying the number of packets which can be received and stored within said second memory; wherein said central processing unit proceeds to the reading of N successive packages into said first memory, which are then transmitted to said Bluetooth communication controller before said central processing unit enters into an idle state; and wherein said Bluetooth communication controller proceeds to encapsulation of packets according to said Bluetooth protocol and emission to said satellite of said encapsulated packets and further monitors the level of filling of said second memory and, upon detection of said level of filling becoming less than said threshold value (T1), generates a signal for controlling reactivation of said central processing unit.
