Problems solved by technology

Although the above solution solves the problem of audio data being overwritten, the solution of using the memory pool also introduces a series of other problems: it is necessary to open up another memory space for separate storage or backup data, and frequent memory copy actions will be to a certain extent The performance of the system is reduced, and the operation process is complicated. At the same time, the maintenance of each data in the newly opened memory space will increase the complexity of the system design, and it is not easy to maintain later

Embodiment 1

[0046] Embodiments of the present invention provide a method for processing audio data, such as figure 1 shown, including:

[0047]Step 101. When a trigger instruction is received, unload the information control node to be configured with unit data from the first queue, and configure the unloaded information control node to be configured. The configured information control node contains audio data to be played attribute information.

[0048] Wherein, the first queue is used to manage the information control nodes to be configured, and the first queue includes at least one information control node to be configured.

[0049] Specifically, a queue is a special linear table that only allows deletion operations at the front end of the table and insertion operations at the back end of the table. The end of the insertion operation is called the tail of the queue, and the end of the deletion operation is called the head of the queue. When there are no elements in the queue, it is c...

Embodiment 2

[0061] On the basis of Embodiment 1, this embodiment of the present invention provides a specific implementation manner, such as figure 2 shown, including:

[0062] Step 201, setting the first queue, the second queue, the third queue and the fourth queue.

[0063] Among them, the first queue is used to manage the information control nodes to be configured, the second queue and the third queue are used to manage the configured information control nodes, and the fourth queue is used to manage the information control nodes that have played audio data. For the convenience of subsequent description, the first queue is called tobe_pushed queue, the second queue is called pushed queue, the third queue is called tobe_played queue, and the fourth queue is called played queue. During initialization, allocate N information control nodes and insert them into the tobe_pushed queue by tail insertion method, N is greater than or equal to 1; the pushed queue, tobe_played queue and played qu...

Embodiment 3

[0134] An embodiment of the present invention provides an audio data processing device. Each functional unit in the audio data processing device executes the corresponding method steps in Embodiment 1 or Embodiment 2. For details, please refer to Embodiment 1 or Embodiment 2. described and will not be repeated here. Such as Figure 9 As shown, the audio data capture device 110 includes:

[0135] The node unloading unit 1101 is configured to unload the information control nodes to be configured with unit data from the first queue when a trigger instruction is received, and configure the unloaded information control nodes to be configured. The configured information control nodes include Attribute information of the audio data to be played, the first queue contains at least one information control node to be configured;

[0136] A node linking unit 1102, configured to link the configured information control nodes to the second queue and the third queue, both of which are used ...

Abstract

Provided are an audio data processing method, apparatus and system, which relate to the technical field of information processing, and are used for avoiding the problem that audio data to be played cannot be overwritten while a memory pool is provided. The audio data processing method comprises: when a trigger instruction is received, unloading an information control node to be configured of unit data from a first queue, and configuring the unloaded information control node to be configured, wherein the configured information control node contains attribute information about audio data to be played; linking the configured information control node into a second queue and a third queue; unloading the configured information control node of the unit data from the third queue; according to the attribute information about the audio data to be played in the unloaded configured information control node, reading the corresponding audio data to be played; and linking the unloaded configured information control node into a fourth queue. The present invention is applied to digital television systems.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to an audio data processing method, device and system. Background technique [0002] In the field of digital television systems, in order to realize normal playback of audio data, the prior art uses a ring buffer to store captured audio data, and then plays the captured audio data. However, when the audio data to be played is stored in the ring buffer, when the write pointer reaches the end address of the ring buffer, it will immediately return to the start address to continue capturing. At the same time, since the capture and reading are performed in parallel, if the audio data at the start address of the previous buffer is not read and played in time, it will cause the unread audio data to be overwritten by the newly captured data, and then Issue causing sound to skip. [0003] In order to avoid the above situation, in the existing scheme, the audio data c...
