Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
The flow chart of the audio/video data transmission method that provides for preferred embodiment according to the present invention shown in Figure 1.As shown in Figure 1, the audio/video data transmission method that preferred embodiment of the present invention provides comprises step 101～105.
In step 101, the receiving thread group receives the audio or video data of corresponding group user transmission according to the group and the corresponding relation of receiving thread group.For example, the corresponding relation of receiving thread group and group can be as shown in the table.
| The receiving thread group | Group |
| Receiving thread group one | The crowd of Legal Service |
| Receiving thread group two | The crowd of technology department |
| Receiving thread group three | The crowd of sales department |
| Receiving thread group four | The crowd of Finance Department |
Wherein, each receiving thread group comprises two receiving threads of creating in advance at least.For example, receiving thread group one comprises 3 receiving threads, and receiving thread group two comprises 4 receiving threads, and receiving thread group three comprises 3 receiving threads, and receiving thread group four comprises 5 receiving threads.Yet the present invention does not limit the number of receiving thread group and the number of the receiving thread that the receiving thread group comprises, as long as guarantee that receiving thread group and group can be corresponding one by one.In practical application, the receiving thread group of respective number can be set according to the number of group.
In step 102, management thread is judged the operating position of receiving thread in all receiving thread groups, and handles the idle receiving thread in the receiving thread group according to control strategy.Wherein, Control strategy is: when the receiving thread in certain receiving thread group can't satisfy the audio or video data that receive corresponding group user transmission one to one, the idle receiving thread that calls in the highest receiving thread group of idle degree according to the priority orders of receiving thread group free time degree was said receiving thread group service; In a special time period, if having idle receiving thread in certain receiving thread group, and said idle receiving thread is not called, and then closes said idle receiving thread.Wherein, the idle degree of receiving thread group is the ratio of idle receiving thread number and total receiving thread number in the receiving thread group.
For example, when two Legal Service's group user transmission of audio or video data, receiving thread group one activates the audio or video data that two receiving threads receive said two Legal Service's group user transmission respectively.If the audio or video data of Legal Service's group user transmission surpass three groups (for example, five groups of audio or video data), then the receiving thread in the receiving thread group one can't satisfy the audio or video data that receive Legal Service's group user transmission one to one.At this moment, management thread can be judged the operating position of receiving thread in other receiving thread groups, and obtains the priority orders of receiving thread group free time degree according to said operating position.For example; Idle receiving thread is 2 in receiving thread group two; Idle receiving thread is 1 in the receiving thread group three; Idle receiving thread is 3 in the receiving thread group four, and then the priority orders of receiving thread group two, three and four idle degree is from high to low: receiving thread group four, receiving thread group two, receiving thread group three.So, management thread is one service of receiving thread group according to the idle thread (for example, two idle receiving threads) that control strategy can call in the receiving thread group four.In addition; If management thread is called the reception service of the audio or video data that still can't satisfy Legal Service's group user transmission after the idle thread in the receiving thread group four, then to call the idle receiving thread in receiving thread group two and the receiving thread group three successively again be one service of receiving thread group to management thread.Wherein, after invoked idle receiving thread is finished the work, will be the service of the receiving thread group under it.
In addition, in a special time period, if management thread detects in certain receiving thread group and has idle receiving thread, and said idle receiving thread do not call by other receiving thread groups, and then said idle receiving thread can be closed.In addition; Idle thread in all thread reception groups is all finished using, and in the time of still can't satisfying the reception demand of audio or video data, management thread can be created the new receiving thread of respective number to carry out corresponding reception operation; Simultaneously, after being finished, close said newly-built receiving thread.
In step 103, each receiving thread writes buffer area with the audio or video data after receiving the audio or video data.
In step 104, the data processing thread is from the information area that buffering area obtains the audio or video data block, and the resolving information district is with the size information of the data field of the size information that obtains previous audio or video data block and said audio or video data block.Wherein, the information area has fixed size.Particularly, each audio or video data block comprises the information area and data field, and the information area comprises the size information and the timestamp of data field of size information, the audio or video data block of previous audio or video data block.For example, the information area consistent length of each audio or video data block is 15 bytes.Wherein, the content of preceding 4 bytes is the size information of previous audio or video data block, and the content of back 4 bytes is the size information of the data field of audio or video data block for this reason, and the content of all the other bytes can be timestamp information.Yet the present invention does not do any qualification to this.In this, above-mentioned timestamp information can guarantee the time synchronized of audio or video data.
In addition, the operation for preventing that buffering area from reading and writing data simultaneously is provided with mutual exclusion lock, thereby the audio or video data of stopping buffering area when visit and read-write the entanglement of data message amount take place, to guarantee the accuracy of audio or video transfer of data.
In step 105, whether the size information of the current previous audio or video data block that obtains of data processing thread checking big or small consistent with previous audio or video data block.If both are consistent, then the data processing thread obtains the data field of the audio or video data block consistent with the size information of the data field of said audio or video data block from buffering area.If both are inconsistent, then the data processing thread abandons the information area of the current audio or video data block of obtaining, and the information area of postponing again and obtaining the audio or video data block towards the district.
In this, be the example explanation with the audio data transmission.Shown in Figure 2 for the sketch map of the audio data block that preferred embodiment provides according to the present invention.As shown in Figure 2, audio data block B comprises information area b1 and data field b2, and information area b1 comprises the size information b12 of data field b2 of size information b11 and the audio data block B of previous audio data block A.
Particularly, the data processing thread obtains the information area b1 of audio data block B from buffering area, and resolving information district b1, thereby obtains the size information b11 of audio data block A and the size information b12 of audio data block B.Then, the size information b11 of the current audio data block A that obtains of data processing thread checking big or small consistent with audio data block A whether.If the data processing thread detects both unanimities, then the data processing thread obtains the data field of the audio data block B consistent with the size information b12 of data field b2 from buffering area.In addition, if the data processing thread detects both when inconsistent, then the data processing thread abandons the information area b1 of audio data block B, obtains the information area of next audio data block again from buffering area.Yet the present invention does not do any qualification to this.In like manner, the block of video data of obtaining for the data processing thread also has corresponding processing.So repeat no more in this.So, can detect previous audio or video data block, thereby be convenient in data transmission procedure, in time find data exception, guarantee the accuracy of transfer of data through the current information area that obtains.
In addition, the data processing thread can be realized from the mode that buffering area obtains the information area or data field in the following manner.When buffering area had the information area or the data field of audio or video data block of the size of meeting the demands, buffering area can eject the information area or the data field of this audio or video data block.So, the data processing thread can directly obtain above-mentioned audio or video data block information district or data field.Otherwise the data processing thread need be waited for to buffering area, having when meeting the demands the big or small information area or data field and just obtain.Yet the present invention does not do any qualification to this.
In practical application, the data processing thread is corresponding with the number of receiving thread.So, help to guarantee the continuity of audio or video transfer of data and the high efficiency of audio or video Data Receiving.In addition, after the data processing thread normally receives the audio or video data, can be with audio or video transfer of data to audio or video decoder, with real-time decoding audio or video data, thereby guarantee the real-time play of audio frequency and video data.
In sum, the transmission method of the audio, video data that preferred embodiment provides according to the present invention, management thread is handled the idle receiving thread in the receiving thread group according to control strategy, thereby has improved the utilance of receiving thread.Simultaneously, can prevent by frequent establishment and close receiving thread and increase the load pressure of server and the expense of system resource.In addition, the data processing thread verifies according to the data block size information whether the transmission of previous audio or video data block is correct, thereby the accuracy of the audio, video data that has guaranteed to receive is convenient in time find data transmission exception.So, the continuity and the high efficiency of audio, video data transmission have been guaranteed.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
