A method for the wireless transmission of audio signals based on the bluetooth - standard and in a wireless manner - microphone unit

摘要

It is a method for wireless transmission of audio signals based on the bluetooth - protocol of a bluetooth - audio source to a computer device (audio sink) is provided. An audio signal, in the bluetooth - audio source is converted into audio data packets. The audio data packets are based on a protocol with access to the l2cap layer of, for example, the radio frequency communication protocol (rfcomm) in l2cap - data packets in the bluetooth audio source can be converted and transmitted wirelessly. The bluetooth - audio source suppressed a retransmission of faulty or not by the depression received l2cap - data packets or reduces the renewed transmission to a predetermined amount, which is limited by the maximum allowable latency is. Thus, a in-step transmission and reproduction of the take place or of the audio signal audio streams. According to the invention, furthermore, a transmission of audio streams or of an audio signal on the l2cap layer with a reduced rate of repetition provided in the event of faulty data packets. By the process according to the invention can be provided by the application layer an access to rfconm or another data transport protocol with access to the coating can be provided l2cap.
