情况三：播放操作表征音频共享播放。Case 3: The play operation represents audio sharing playback.

由于每路音频数据相同，因此，显示设备可以直接将多路音频数据通过多个蓝牙通路发送至多个播放设备。需要说明的是，在情况三中，可以基于同步广播串流(BroadcastIsochronous Stream，BIS)传输方式，BIS是一种无连接的等时传输，单向通讯，用于将一个或多个等时数据流传输到BIS范围内的所有设备。本申请实施例中，S501、S502具体可在显示设备中的蓝牙协议栈端执行。Since the audio data of each channel is the same, the display device can directly send multiple channels of audio data to multiple playback devices through multiple bluetooth channels. It should be noted that, in case three, it can be based on the Broadcast Isochronous Stream (BIS) transmission method. BIS is a connectionless isochronous transmission, one-way communication, and is used to transmit one or more isochronous data Stream to all devices within range of the BIS. In the embodiment of the present application, S501 and S502 may be specifically executed on the Bluetooth protocol stack side in the display device.

在一些实施例中，由于多个播放设备播放不同的音频数据，因此，若多个播放设备之间的数据不同步，那么，在多个播放设备进行音频播放时，组合出的声音会严重失真，影响用户使用体验。本申请实施例中，在显示设备端，可以对每个发出的数据包进行时序处理，以避免由于系统负载不均衡或者网络环境差造成的数据不同步。In some embodiments, since multiple playback devices play different audio data, if the data between multiple playback devices is not synchronized, then when multiple playback devices perform audio playback, the combined sound will be severely distorted , affecting user experience. In the embodiment of the present application, at the display device side, timing processing can be performed on each sent data packet to avoid data out-of-sync due to unbalanced system load or poor network environment.

具体的，每路音频数据各自对应一个数据包集合，显示设备将多路音频数据，发送至多个播放设备时，可以采用但不限于以下方式：针对每路音频数据，若一路音频数据对应的数据包集合中，一个数据包的发送等待时长大于预设的时长阈值，则显示设备将一个数据包丢弃，其中，发送等待时长用于表征从确定发送一个数据包的时刻至当前时刻的时长。Specifically, each channel of audio data corresponds to a data packet set. When the display device sends multiple channels of audio data to multiple playback devices, the following methods can be used but not limited to: For each channel of audio data, if the data corresponding to one channel of audio data In the packet set, if the sending waiting time of a data packet is greater than the preset time threshold, the display device will discard a data packet, wherein the sending waiting time is used to represent the time from the time when a data packet is determined to be sent to the current time.

示例性的，显示设备可以采用时间窗口进行数据包的发送或丢弃，时间窗口的窗口大小为预设的时长阈值10毫秒。时间窗口可以采用但不限于滚动窗口、滑动窗口等，本申请对此不作限定。该时间窗口随时间向前滑动，窗口内的数据包随着音频播放而发生变化。具体为，随着时间推移，新的数据包进入时间窗口，而最先进入时间窗口的数据包被移出窗口。Exemplarily, the display device may use a time window to send or discard data packets, and the window size of the time window is a preset duration threshold of 10 milliseconds. The time window may adopt, but is not limited to, a rolling window, a sliding window, etc., which are not limited in this application. This time window slides forward with time, and the packets within the window change as the audio plays. Specifically, as time goes by, new data packets enter the time window, and the data packets that first enter the time window are moved out of the window.

在一些实施例中，为了实现音频播放过程中音画同步的改善，显示设备可以通过改变编解码码率，改变音频数据的播放速度，从而达到音画同步的效果。In some embodiments, in order to improve the audio-video synchronization during audio playback, the display device can change the codec rate and the playback speed of the audio data, so as to achieve the effect of audio-video synchronization.

具体的，在多路音频数据的传输过程中，显示设备响应于目标对象触发的音质配置操作，获取目标音质；基于目标音质，调整多路音频数据的编解码码率(简称码率)。其中，码率是指在单位时间内播放连续的音频数据的比特数量，码率又可以称为比特率。Specifically, during the transmission of multiple channels of audio data, the display device acquires the target voice quality in response to the voice quality configuration operation triggered by the target object; based on the target voice quality, adjusts the encoding and decoding code rate (code rate for short) of the multiple channels of audio data. Wherein, the code rate refers to the number of bits of continuous audio data played within a unit time, and the code rate may also be referred to as a bit rate.

示例性的，可以采用低复杂度编解码器(Low Complexity Communication Codec，LC3)编解码器进行音频数据的编解码，LC3编解码器是一种用于LE Audio的音频编解码器，能够以各种码率编解码音频。Exemplarily, a low complexity codec (Low Complexity Communication Codec, LC3) codec can be used to encode and decode audio data. The LC3 codec is an audio codec for LE Audio, and can be used in various Codec audio at a bit rate.

本申请实施例中，可以预先设置不同音质和不同码率之间的映射关系，进而，显示设备获取到目标码率后，可以基于预设的映射关系，确定目标音质对应的目标码率，进而基于目标码率对多路音频数据进行编解码。例如，标准音质对应128K，较高音质对应260K。In the embodiment of the present application, the mapping relationship between different sound qualities and different bit rates can be preset, and then, after the display device acquires the target bit rate, it can determine the target bit rate corresponding to the target sound quality based on the preset mapping relationship, and then Encode and decode multiple channels of audio data based on the target bit rate. For example, standard sound quality corresponds to 128K, and higher sound quality corresponds to 260K.

由于蓝牙带宽限制，声音数据流越大，丢包等问题就会越明显，进而引发声音断续、卡顿等问题。针对此问题，显示设备可以自动判断使用的BIS通路数，根据使用的BIS通路数，动态调整码率，通过改变音质以达到数据的清晰与连续例如，在使用四路BIS时，可以减小音质，在使用一路BIS时，可以提高音质。Due to the limitation of Bluetooth bandwidth, the larger the sound data stream, the more obvious problems such as packet loss will be, which will cause problems such as intermittent sound and stuttering. To solve this problem, the display device can automatically judge the number of BIS channels used, dynamically adjust the code rate according to the number of BIS channels used, and achieve clear and continuous data by changing the sound quality. For example, when using four-channel BIS, the sound quality can be reduced , when using one BIS, the sound quality can be improved.

参阅图8所示，其为本申请实施例中提供的一种音频播放方法的流程示意图，应用于播放设备x，播放设备x为多个播放设备中的任意一个播放设备，具体的，该音频播放流程如下：Referring to FIG. 8 , it is a schematic flowchart of an audio playback method provided in the embodiment of the present application, which is applied to a playback device x, and the playback device x is any playback device among multiple playback devices. Specifically, the audio The playback process is as follows:

S801、播放设备x基于目标蓝牙通路的通路标识，从多路音频数据各自对应的蓝牙通路中，确定目标音频通路。S801. Based on the channel identifier of the target Bluetooth channel, the playback device x determines the target audio channel from the corresponding Bluetooth channels of multiple channels of audio data.

其中，多路音频数据是显示设备基于目标对象触发的播放操作，对待播放音频进行音频解析后得到的。Wherein, the multi-channel audio data is obtained by the display device after performing audio analysis on the audio to be played based on the playback operation triggered by the target object.

具体的，目标蓝牙通路的建立过程与S602中涉及的蓝牙通路的确定过程相同，在此不再赘述。Specifically, the establishment process of the target Bluetooth path is the same as the determination process of the Bluetooth path involved in S602, and will not be repeated here.

S802、播放设备x通过目标音频通路，接收并播放对应的目标音频数据。S802. The playback device x receives and plays corresponding target audio data through the target audio channel.

由于不同品牌、型号的播放设备之间的数据处理时长是不同的，因而导致从不同播放设备接收到音频数据后，播放音频数据的时刻是不同的，进而导致多个播放设备同时播放多个音频数据时，音频数据不同步。为避免多个播放设备之间的处理时长导致的数据不同步的问题，本申请实施例中，播放设备在接收到相应的音频数据之后，可以通过调整自身的缓冲区大小，控制不同的播放设备的音频数据的播放时刻。Since the data processing time between different brands and models of playback devices is different, the timing of playing audio data after receiving audio data from different playback devices is different, which in turn causes multiple playback devices to play multiple audio files at the same time. data, the audio data is out of sync. In order to avoid the problem of data out-of-sync caused by the processing time between multiple playback devices, in the embodiment of this application, after receiving the corresponding audio data, the playback device can control different playback devices by adjusting its own buffer size The playing time of the audio data.

具体的，在播放设备x接收目标音频数据之后，播放设备x可以将目标音频数据，存储于对应目标音频数据设置的缓冲区中，其中，缓冲区的大小是根据目标对象的配置操作确定的。进而，在播放设备x播放目标音频数据的过程中，播放设备x可以从缓冲区中，读取并播放目标音频数据。Specifically, after the playback device x receives the target audio data, the playback device x can store the target audio data in a buffer set corresponding to the target audio data, wherein the size of the buffer is determined according to the configuration operation of the target object. Furthermore, during the process of playing the target audio data by the playback device x, the playback device x can read and play the target audio data from the buffer.

以播放设备x为音响1为例，假设，目标音频数据为左声道音频数据，音响1接收到左声道音频数据之后，将左声道音频数据存储于对应左声道音频数据设置的缓冲区中。由于缓冲区中数据量越大，音频数据的播放时间就越晚，因此，在音响1播放左声道音频数据的过程中，若左声道音频数据比其他音频数据播放的快，则用户可以通过增大缓冲区的大小，延缓左声道音频数据的播放时刻，若左声道音频数据比其他音频数据播放的慢，则用户可以通过减小缓冲区的大小，加快左声道音频数据的播放时刻。这样，通过目标对象的配置操作，可以动态调整缓冲区的大小，从而实现不同音频数据之间的数据同步。Take audio 1 as the playback device x as an example, assuming that the target audio data is the left channel audio data, after audio 1 receives the left channel audio data, it stores the left channel audio data in the buffer set corresponding to the left channel audio data in the district. As the amount of data in the buffer is larger, the playing time of the audio data is later. Therefore, in the process of playing the left channel audio data on the stereo 1, if the left channel audio data is played faster than other audio data, the user can By increasing the size of the buffer, the playback time of the left channel audio data is delayed. If the left channel audio data is played slower than other audio data, the user can reduce the size of the buffer to speed up the left channel audio data. play moment. In this way, through the configuration operation of the target object, the size of the buffer can be dynamically adjusted, thereby realizing data synchronization between different audio data.
