[0051] Figure 1 An application scenario of a data transmission method provided by an embodiment of the present application is shown in FIG. 1. The scenario shown in FIG. 1 is an example of an audio device including a system chip and a digital signal processor. The system chip is inside the audio device, and the digital signal processor is outside the audio device. The digital signal processor is connected to a microphone and a speaker. The system chip generates playback data and transmits the data to the digital signal processor. The digital signal processor plays the data through the speaker. The microphone receives recording data from a user and transmits the data to the digital signal processor. The digital signal processor transmits the recording data to the system chip inside the audio device, and processes the recording data.

[0052] The technical solutions of the present application and the technical solutions of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. In the description of the present application, unless otherwise specified and limited, each term should be understood in a broad sense in the art. The embodiments of the present application will be described below with reference to the drawings.

[0053] Figure 2A flowchart of a data transmission method provided by an embodiment of the present application is shown in the figure. The method comprises the following steps:

[0054] S201: Determine a first frame width of original play data.

[0055] For example, the execution subject of the embodiment can be a data transmission device, which can be implemented in various ways. For example, it can be a program software, a medium storing a related computer program, such as a U disk, or an entity device integrated or installed with a related computer program, such as a chip, a smart terminal, a computer, a server, etc.

[0056] The play data is generated by a system-level chip, sent to a digital signal processor through an audio transmission channel, and played through a loudspeaker connected to the digital signal processor. The play data comprises multiple audio channels, and the digital signal processor plays the audio channels through the loudspeaker after locating the audio channels, thereby avoiding loss or disorder of the audio channels.

[0057] S202: Split the original play data according to the first frame width to obtain a first sequence comprising multiple original play data segments.

[0058] The original play data is composed of multiple original play data segments connected in sequence, and the connection between every two adjacent original play data segments is removed after the splitting, without changing the sequence.

[0059] It can be understood that the original play data segments obtained by splitting according to the first frame width comprise complete audio channels.

[0060] S203: Determine target play data according to the first sequence.

[0061] The difference between the target play data and the original play data is that there is no connection between two adjacent original play data segments in the target play data.

[0062] S204: Determine the first frame width as a first channel bit width of a first audio transmission channel, and send the target play data to a digital signal processor through the first audio transmission channel.

[0063] Optionally, the interface of the first audio transmission channel can set the channel bit width, and the first channel bit width can be set as the first frame width, so that the length of the play data segments in the target play data does not change during transmission.

[0064] Further optionally, the interface of the first audio transmission channel comprises but is not limited to an integrated audio interface and a time division multiplex bus communication interface.

[0065] The data transmission method provided in the embodiments of the present application comprises the following steps: determining a first frame width of original playback data; splitting the original playback data according to the first frame width to obtain a first sequence comprising a plurality of original playback data segments; determining target playback data according to the first sequence; determining the first frame width as a first channel bit width of a first audio transmission channel, and sending the target playback data to a digital signal processor through the first audio transmission channel. The above scheme splits the playback data into playback data segments and then sends the playback data segments to the digital signal processor, and each playback data segment comprises complete channels, so that the channel positioning accuracy is improved by a software method when the channel positioning cannot be realized by hardware of the digital signal processor.

[0066] On the basis of any one of the above embodiments, the following will be described in combination with Figure 3 The detailed process of data transmission is described.

[0067] Figure 3 A flowchart of a data transmission method provided in the embodiments of the present application is shown in FIG. 2. As shown in FIG. 2, the method comprises the following steps. Figure 3

[0068] S301: obtaining a first channel number and a first channel bit width of original playback data.

[0069] In the related art, channel positioning is performed by hardware functions of a system on chip and a digital signal processor. However, in actual application, some digital signal processors do not have the channel positioning function or the digital signal processor fails to position.

[0070] S302: determining a product of the first channel number and the first channel bit width as a first frame width of the original playback data.

[0071] In combination with a scene example, the original playback data is 2 channels, and the first channel bit width is 8 bits, so the first frame width is 16 bits.

[0072] S303: splitting the original playback data according to the first frame width to obtain a first sequence comprising a plurality of original playback data segments.

[0073] It should be noted that the execution process of S303 is described in S202, which is not described herein again.

[0074] S304: copying each original playback data segment in the first sequence to obtain a copied playback data segment corresponding to each original playback data segment.

[0075] It can be understood that the copied playback data segment is completely consistent with the corresponding original playback data segment, and the channels of the copied playback data segment are completely consistent with the channels of the corresponding original playback data segment.​

[0076] Optionally, playback data is transmitted via left and right clock signals, wherein the original playback data segment is used to fill the left channel of the left and right clock signals, and the copied playback data segment is used to fill the right channel of the left and right clock signals.

[0077] S305. Determine the insertion position of each copied playback data segment in the first sequence.

[0078] In a scenario example, each copied playback data segment is inserted after its corresponding original playback data segment in the first sequence. The relative order of the original playback data segments is determined by the first sequence.

[0079] S306. Based on the insertion position of each copied playback data segment, insert the corresponding copied playback data segment into the first sequence to obtain the target playback data.

[0080] Below, in conjunction with Figure 4 Explanation of the generated target playback data.

[0081] Figure 4 This is a schematic diagram illustrating the generation of target playback data provided in an embodiment of this application. For example... Figure 4 As shown, for 2-channel playback data, the original playback data segment is also 2-channel. D0 and D1 represent the two channels of the original playback data segment 1. The d0 and d1 channels of the copied playback data segment 1 are the same as the D0 and D1 channels. The copied playback data segment 1 is inserted after the original playback data segment 1.

[0082] The above scheme illustrates how a system-on-a-chip (SoC) sends playback data to a digital signal processor (DSP). Next, we will illustrate how a SoC receives recording data sent by a DSP.

[0083] One feasible implementation method further includes: receiving target recording data sent by the digital signal processor through a second audio transmission channel; identifying the target recording data to obtain valid recording data.

[0084] In a scenario example, the recording data is generated by a digital signal processor (DSP). The DSP processes the raw recording data to obtain the target recording data. The raw recording data is complete. If the system-on-a-chip (SoC) performs channel localization on the complete raw recording data based on hardware functions, it may fail to locate the channel. However, the target recording data includes multiple recording data segments. The SoC can directly locate the channel from a recording data segment containing only one set of channels, avoiding the influence of different recording data segments in the complete raw recording data on the accuracy of channel localization.

[0085] A possible implementation manner is that the target recording data is identified to obtain valid recording data, including: determining a second channel bit width of the second audio transmission channel; identifying the target recording data until N continuous zero data are identified, and then determining non-zero data after the N continuous zero data as the valid recording data, where N is a quantity corresponding to the second channel bit width, and N is an integer greater than or equal to 1.

[0086] Next, in combination with Figure 5 The valid recording data is described.

[0087] Figure 5 An identification valid recording data schematic diagram provided by an embodiment of the present application is shown in FIG. 2. Figure 5 As shown in the figure, the target recording data is N valid data segments and N zero data arranged alternately, so if N continuous zero data are identified, the next data is a complete valid data segment, and all the subsequent zero data can be removed to obtain valid data.

[0088] In this possible implementation manner, by identifying N continuous zero data, the integrity of the subsequent valid data can be ensured, thereby improving the accuracy of sound channel positioning.

[0089] Figure 6 A flowchart of a data transmission method provided by an embodiment of the present application is shown in FIG. 3, which is applied to a digital signal processor end. Figure 6 As shown in the figure, the method includes:

[0090] S601, determining a second frame width of original recording data.

[0091] The recording data is generated by a digital signal processor according to a sound received by a microphone.

[0092] S602, splitting the original recording data according to the second frame width to obtain a second sequence including a plurality of original recording data segments.

[0093] The original recording data is a plurality of original recording data segments connected in sequence, and after splitting processing, each adjacent two original recording data segments are disconnected without changing the sequence.

[0094] It can be understood that the original recording data segment obtained by splitting according to the second frame width includes a complete audio channel.

[0095] S603, determining target recording data according to the second sequence.

[0096] The difference between the target recording data and the original recording data is that there is no connection between the adjacent two original recording data segments of the target recording data.

[0097] S604, determine the second frame width as a second channel bit width of a second audio transmission channel, and send the target recording data to a system level chip through the second audio transmission channel.

[0098] Optionally, the interface of the second audio transmission channel can set the channel bit width, and the second channel bit width is set as the second frame width, so that the length of the recording data segment of the target recording data does not change during transmission.

[0099] On the basis of any one of the above embodiments, the following will be described in combination with Figure 7 The detailed process of data transmission is described.

[0100] Figure 7 A flowchart of a data transmission method provided by the embodiment of the application is shown in FIG. 3. Figure 7 The method includes the following steps.

[0101] S701, obtain a second channel number and a second channel bit width of original recording data.

[0102] It should be noted that the execution process of S701 is referred to S301, which will not be described here.

[0103] S702, determine the product of the second channel number and the second channel bit width as a second frame width of the original recording data.

[0104] It should be noted that the execution process of S702 is referred to S302, which will not be described here.

[0105] S703, split the original recording data according to the second frame width to obtain a second sequence including a plurality of original recording data segments.

[0106] It should be noted that the execution process of S703 is referred to S602, which will not be described here.

[0107] S704, generate zero data according to the second frame width.

[0108] It can be understood that the frame width of the zero data is consistent with the second frame width. For example, if the second frame width of the original recording data is 16 bits, then the frame width of the zero data is also 16 bits.

[0109] S705, determine the insertion position of the zero data in the second sequence.

[0110] With the scene example, the insertion position of each zero data is between each two original recording data segments in the second sequence. One zero data is inserted between each two original recording data segments. The relative position sequence between each original recording data segment is determined by the second sequence.

[0111] S706, inserting the zero data in the second sequence according to the insertion position of the zero data, to obtain the target recording data.

[0112] Next, the generation of the target recording data is described in combination with Figure 8 The generation of the target recording data is described.

[0113] Figure 8 The generation of the target recording data is described. Figure 8 As shown, for 2 channels, the original recording data of the second channel has a bit width of 8 bits, the frame width of the zero data is 16 bits, the second frame width of the original recording data segment is consistent with that of the zero data, and E0 and E1 represent 2 channels of the original recording data segment 1. A piece of zero data is inserted between each two adjacent original recording data segments, to generate the target recording data.

[0114] The above scheme is an example description of the digital signal processor sending recording data to the system-on-chip. Next, the digital signal processor receiving the playback data sent by the system-on-chip is described as an example.

[0115] A feasible implementation manner, the data transmission method further comprises: receiving the target playback data sent by the system-on-chip through the first audio transmission channel; identifying the target playback data to obtain valid playback data.

[0116] With the scene example, the playback data is generated by the system-on-chip, the system-on-chip processes the original playback data to obtain the target playback data, the original playback data is complete playback data, and the digital signal processor performs channel positioning based on hardware functions when the complete original playback data is positioned, which has the problem of positioning failure. The target playback data includes multiple playback data segments, and the digital signal processor can directly position the channel from the playback data segment containing only one group of channels, avoiding the influence of the channels of different playback data segments in the complete original playback data on the accuracy of positioning the channel.

[0117] A feasible implementation manner, the target playback data is transmitted through left and right clock signals; identifying the target playback data to obtain valid playback data comprises: identifying the left and right clock signals to obtain a target level jump; determining the target playback data segment corresponding to the target level jump and the target playback data segment corresponding to each level jump separated by one level jump after the target level jump as the valid playback data.

[0118] Below, in conjunction with Figure 9 Explanation of the identification of valid playback data.

[0119] Figure 9 This is a schematic diagram illustrating the identification of valid playback data provided in an embodiment of this application. For example... Figure 9 As shown, the target playback data consists of alternating original playback data segments and copied playback data segments. Since the original and copied playback data segments are identical, redundant data segments need to be removed to obtain valid data. The original playback data segments fill the left channel of the left and right clock signals, while the copied playback data segments fill the right channel. During transmission via the left and right clock signals, a level jump occurs between the original and copied playback data segments. This level jump determines the boundary between the original and copied playback data segments. Figure 5 If both sampling points 1 and 2 produce level jumps, and the digital signal processor (DSP) determines sampling point 1 as the target sampling point, then the original playback data segment 1 following sampling point 1, and the original playback data segment 2 and original playback data segment 3 separated by one level jump are determined as valid playback data. If the DSP determines sampling point 2 as the target sampling point, then the copied playback data segment 1 following sampling point 2, and the copied playback data segment 2 and copied playback data segment 3 separated by one level jump are determined as valid playback data.

[0120] In this feasible implementation, the digital signal processor can identify the boundary points between playback data segments by using left and right clock signals, and the identified playback data segments can be combined to form complete playback data, thereby improving the accuracy of channel positioning.

[0123] The first splitting module 102 is used to split the original playback data according to the first frame width to obtain a first sequence including multiple original playback data segments.

[0124] The first generation module 103 is used to determine target playback data based on the first sequence.

[0125] The first transmission module 104 is configured to determine the first frame width as a first channel bit width of a first audio transmission channel, and transmit the target playback data to a digital signal processor through the first audio transmission channel.
