[0003] However, the above transfer method is only reasonable when there is peer-to-peer data between the first device and the second device
For example, for wireless microphones to speakers, which require one-way transmission, this solution is obviously unreasonable, that is, the existing solutions at least have the problem of not being able to effectively use system resources

Embodiment Construction

[0049] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0050] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0051] See figure 1 , figure 1 It is a schematic diagram of transmission of wireless audio data based on the existing Bluetooth standard protocol. By introducing the concept of a time slot, the Bluetooth system can realize basically symmetrical two-way wireless transmission between the first device and the second device.

[0052] For example, if figure 1 A...

Abstract

The embodiment of the invention provides a wireless audio data sending method and device and a wireless audio data receiving method and device, and the method comprises: first device generating N audio frames, and N being an integer larger than or equal to 2; wherein the first device sends N audio frames to the second device through N continuous periods, each period corresponding to one audio frame, each audio frame comprising the following fields: a frame header, an identifier of the first device and a frame length, and the frame header being used for synchronization of the first device and the second device. According to the embodiment of the invention, the audio frame is sent to the second device through the continuous period, so that the requirement of a one-way transmission scene is met, and the system resource can be effectively utilized.

Description

technical field [0001] The present application relates to the technical field of audio processing, and in particular to a sending method, a receiving method and a device for wireless audio data. Background technique [0002] At present, the transmission of audio frames based on the Bluetooth (Bluetooth) standard protocol on the market is basically symmetrical. For example, in the case of transmitting audio frames between the first device and the second device, within the same time period, the first device The amount of data transmitted to the second device is substantially equal to the amount of data transmitted from the second device to the first device. [0003] However, the above transfer method is only reasonable when there is peer-to-peer data between the first device and the second device. For example, for the one-way transmission from wireless microphone to speaker, this solution is obviously unreasonable, that is, the existing solutions at least have the problem of ...
