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, receiving audio data; the audio data includes M sections of frame data and CRC check information corresponding to each section of frame data;
[0032] Step 102. When the audio data in the N retransmission windows are all erroneous data, restore the audio data according to the CRC check information in the N erroneous audio data; where 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 segmentally adding several CRC check bytes in the transmitted data packet.
[0034] During specific implementation, when audio data is transmitted through Bluetooth, the controller CONTROLLER layer of the receiving end of the Bluetooth signal will directly upload to the host HOST laye...
Embodiment 2
[0070] Based on the same inventive concept, the embodiment of the present application also provides an audio data recovery device. Since the problem-solving principle of the audio data recovery device is similar to the method provided in Embodiment 1 of the present application, the implementation of the audio data processing device can be Refer to the implementation of the method, and the repetition will not be repeated.
[0071] figure 2 A schematic structural diagram of an audio data recovery device according to an embodiment of the present application is shown. As shown in the figure, the device includes:
[0072] The receiving module 201 is configured to receive audio data; the audio data includes M sections of frame data and CRC check information corresponding to each section of frame data;
[0073] The recovery module 202 is used to restore the audio data according to the CRC check information in the N erroneous audio data when the audio data in the N retransmission wi...
Embodiment 3
[0090] Based on the same inventive concept, the embodiment of the present application also provides a bluetooth device. Since the principle of the bluetooth device to solve the problem 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, repeat The place will not be repeated.
[0091] image 3 A schematic diagram of the structure of the Bluetooth device according to the 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 device in Embodiment 2 of the present application.
[0092] During specific implementation, the bluetooth device in the embodiment of the present application may include a bluetooth headset, a bluetooth speaker, a bluetooth gateway, a bluetooth mp3, a bluetooth flash disk, a bluetooth vehicle-mounted device, a bluetooth a...
