detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Embodiments of the present invention provide an audio file transmission method, apparatus, and audio receiving method and apparatus. The foregoing method and apparatus can provide audio files in a user terminal device such as a personal PC or a mobile phone to a Bluetooth headset, a Bluetooth speaker, and the like. Bluetooth device, and audio file storage on the Bluetooth device side, the following examples illustrate the application environment of the above method and device.

1 is a schematic diagram of an application environment of an audio file processing system according to an embodiment of the present invention; Figure 1 (a), Figure 1 (b) and Figure 1 (c) show three application scenarios for providing an audio file to the Bluetooth device 10 through the user terminal device 20, wherein the application scenario may further include a user (Figure The user may interact with the user terminal device 20 and the Bluetooth device 10 through any suitable type of one or more user interaction devices, for example, the user interaction device may be a mouse, a button, a remote controller. The touch screen, the somatosensory camera or the smart wearable device controls the user terminal device 20 and the Bluetooth device 10 to perform one or more operations, such as an audio playback operation, by inputting an instruction.

The user terminal device may be any suitable type of user terminal device providing one or more audio content, such as a smartphone, a tablet, an MP3 player, a personal computer, a laptop, a personal stereo, a CD player or the like. Intelligent / non-intelligent terminal equipment. The user terminal device is coupled to at least one storage medium for storing audio data, which may be a memory within the user terminal device, or may be a storage medium on the Internet, and acquire an audio file from the storage medium. Furthermore, the user terminal device may also be a combination of one or more electronic devices, such as a smartphone and an analog to digital converter (DAC) connected thereto.

The Bluetooth device can be any suitable device having the ability to play audio data and storage capabilities, such as a Bluetooth headset, a Bluetooth speaker, or other suitable type of speaker set. Fig. 1(a) shows a scenario in which audio data is supplied to a Bluetooth speaker through a personal PC. The FIG. 1(b) shows a scenario in which audio data is supplied to a Bluetooth speaker through a personal PC, and FIG. 1(c) shows a scenario in which audio data is supplied to a Bluetooth headset through a mobile phone.

The user terminal device can connect to the Bluetooth device through an internal integration or an external Bluetooth module or a Bluetooth chip. When two Bluetooth-enabled devices establish a connection, they get the protocol provided by the corresponding device. Only devices that use the same protocol can exchange data.

In Bluetooth communication, Bluetooth-enabled devices do not need to implement the full Bluetooth specification. In order to support compatibility between different Bluetooth devices, some application layer profiles are defined in the Bluetooth specification to define how a connection or application is implemented between Bluetooth-enabled devices.

Among them, A2DP (Advenced Audio Distribution Profile) belongs to a subset of the above Bluetooth protocol profiles. A protocol stack and method of use for transferring high quality music file data, A2DP is specifically designed to transmit stereo audio using Bluetooth.

HFP (Hands Free Profile), HFP can only transmit mono encrypted audio, and the transmission quality is much worse than A2DP. A2DP can transmit (16bits, 44.1kHz) audio, while HFP can only transmit (8bits, 8kHz) audio, HFP can be used to transmit voice signals.

BLE (Bluetooth low energy), which is a Bluetooth low energy protocol, is mainly used for short-time small data transmission.

The user terminal device can establish a Bluetooth connection with the Bluetooth device according to the user instruction, wherein the user terminal device can transmit the audio data to the Bluetooth device through the first Bluetooth audio transmission protocol (for example, A2DP protocol or HFP protocol), and pass the second Bluetooth. A transport protocol (eg, the BLE protocol) delivers audio information related to the audio data to the Bluetooth device (eg, the name of the music, the name of the singer or player, the music category, and the voice issuer, etc.). An audio folder is created in a memory of the Bluetooth device according to the audio information, and the audio data is stored in the audio folder to implement storage of the audio file in the Bluetooth device.

The embodiments of the present invention are not limited to the above Bluetooth protocol. In practical applications, other suitable Bluetooth protocols may be used as needed to transmit audio data and other suitable protocols for transmitting audio information.

When an audio file is played by a user terminal device integrated with a Bluetooth chip, the Bluetooth chip can receive an audio signal through a Pulse Code Modulation (PCM) wired CODEC interface (for example, a standard hardware stereo PCM interface) (the audio signal can be in MP3 format or other format) Decoding the audio signal and outputting PCM audio bare data. Since the PCM audio bare data requires a large bandwidth, that is, inefficient and power-consuming, and is not suitable for wireless transmission, it is necessary to perform audio encoding on the PCM audio bare data to compress it, and then, the compressed audio data is sub-packaged and combined. Into the audio data of the Bluetooth transmission protocol. When the A2DP protocol is adopted, it is combined into an A2DP audio data frame, such as frame1, frame2, ... frameN. After receiving the compressed and packetized audio data, the Bluetooth device can directly store the compressed and packetized audio data in the audio folder, and then decode it when it needs to be played. After decoding, The audio data is then stored in an audio folder.

In the A2DP protocol, audio coding formats that satisfy the A2DP protocol include SBC (Sub Band Coding), AAC (Advanced Audio Coding), and Apt-X. Among them, the encoding rate of the SBC encoding format is 44.1 kHz and the maximum is 328 kbit/s, the encoding rate of the AAC encoding format is 320 kbit/s, and the encoding rate of the Apt-X encoding format is 352 kbit/s.
