Embodiment 1
[0030] figure 1 A schematic diagram of the implementation of the audio data recovery method in the embodiment of the present application is shown. As shown in the figure, the method includes:
[0031] Step 101, receive audio data; Described audio data comprises M segment frame data and the CRC check information corresponding to each segment frame data;
[0032] Step 102, when the audio data of the N retransmission windows are all erroneous data, recover the audio data according to the CRC check information in the N erroneous audio data; wherein, M and N are positive Integer.
[0033] The audio data recovery method provided by the embodiment of the present application recovers erroneous audio data by adding several CRC check bytes into segments in a transmitted data packet.
[0034] In specific implementation, when audio data is transmitted through Bluetooth, the CONTROLLER layer of the controller at the receiving end of the Bluetooth signal will directly upload the correct d...
Embodiment 2
[0070] Based on the same inventive concept, the embodiment of the present application also provides an audio data recovery device. Since the principle of the audio data recovery device for solving the problem is similar to the method provided in the first embodiment of the present application, the implementation of the audio data processing device can be Refer to the implementation of the method, and the repeated places will not be repeated.
[0071] figure 2 A schematic structural diagram of an audio data recovery apparatus according to an embodiment of the present application is shown. As shown in the figure, the apparatus includes:
[0072] A receiving module 201 is used to receive audio data; the audio data includes M segments of frame data and CRC check information corresponding to each segment of frame data;
[0073] The recovery module 202 is configured to recover the audio data according to the CRC check information in the N wrong audio data when the audio data of th...
Embodiment 3
[0090] Based on the same inventive concept, an embodiment of the present application also provides a Bluetooth device. Since the principle of solving the problem of the Bluetooth device is similar to the method provided in Embodiment 1 of the present application, the implementation of the Bluetooth device can refer to the implementation of the method, repeating will not be repeated here.
[0091] image 3 A schematic structural diagram of a Bluetooth device according to an embodiment of the present application is shown. As shown in the figure, the Bluetooth device provided by the embodiment of the present application includes the audio data recovery apparatus in Embodiment 2 of the present application.
[0092] During specific implementation, the Bluetooth devices in the embodiments of this application may include Bluetooth headsets, Bluetooth speakers, Bluetooth gateways, Bluetooth MP3s, Bluetooth flash drives, Bluetooth vehicle-mounted devices, Bluetooth adapters, etc., whic...
