First embodiment
As shown in fig. 1, a first embodiment of the present invention provides an audio playing method applied to a broadcast terminal, including:
The broadcasting task information comprises the starting playing time and the playing period of the audio file to be played by the broadcasting terminal. It should be noted that, after receiving the broadcast task information, the broadcast terminal writes the content of the broadcast task information into its own storage device, so that after the broadcast terminal is restarted, the broadcast task corresponding to the broadcast task information is still valid.
And 102, playing the audio file according to the starting playing time and the playing period of the audio file.
In the first embodiment of the present invention, after receiving the playback task information, the broadcast terminal can periodically play back the audio file according to the start playback time and the playback period of the audio file. Specifically, the broadcasting terminal may implement the periodic playing of the audio file by creating a timer or by scanning in a timed round-robin manner. It is worth one that the control server can send the playing task information to the broadcast terminal in advance (i.e. before the beginning playing time of the audio file), so as to reduce the requirement on the IP bandwidth of the control server and reduce the operation investment of the user on the bandwidth. Meanwhile, the problem that the audio playing is blocked due to insufficient bandwidth of the control server at the broadcasting terminal can be avoided, and the user experience is improved.
In the first embodiment of the present invention, the playback task information further includes an end time of the playback task, so that after the step of playing back the audio file according to the start playback time and the playback period of the audio file, the method further includes the following steps: and deleting the audio file when the ending time of the playing task is detected to arrive.

And thirdly, playing the audio files stored by the broadcast terminal according to the starting playing time and the playing period of the audio files.
In the first embodiment of the present invention, if the audio file to be played is downloaded from the file transfer server, the audio file may be encrypted. Therefore, in the first embodiment of the present invention, after the step of downloading the audio file from the file transfer server according to the download address is performed, the method further includes the following steps: and receiving a key which is sent by the control server and used for decrypting the audio file downloaded from the file transmission server, and decrypting the downloaded audio file according to the key. Therefore, the broadcasting terminal can play the acquired audio file according to the starting playing time and the playing period of the audio file.
In a first embodiment of the present invention, the playback task information further includes a name of an audio file, and correspondingly, the method further includes the following steps: in the process of playing the audio file, the name of the audio file currently played by the broadcast terminal and the playing progress information of the audio file are sent to the control server, so that a user at the side of the control server can conveniently know the playing state of the broadcast terminal.
In the first embodiment of the present invention, before performing step 101, to ensure communication between the broadcast terminal and the control server, the method further includes the following steps:
first, a handshake request message is sent to a control server.
And step two, receiving a handshake response message returned by the control server.
In the first embodiment of the present invention, the broadcast terminal may establish a communication connection with the control server through the handshake request message and the handshake response message, so as to implement bidirectional communication. And the handshake reply message can carry time information so as to synchronize the broadcast terminal and the control server.
And thirdly, sending a legality verification request message to the control server according to the handshake response message, wherein the legality verification request message comprises the identity information of the broadcast terminal.
And fourthly, receiving a verification message which is sent by the control server and used for indicating that the broadcast terminal is legal.
In the first embodiment of the present invention, only when the broadcast terminal is legal, the broadcast terminal can interact with the control server to receive the broadcast task information sent by the control server. It should be noted that, in order to ensure the security of the interaction, any information (i.e. the playing task information, the key for decrypting the audio file downloaded from the file transfer server, etc.) interacted between the broadcast terminal and the control server may be processed in an encryption manner agreed in advance by the broadcast terminal and the control server. That is, the broadcast terminal needs to decrypt the information after receiving any information sent by the control server, and accordingly, the broadcast terminal needs to encrypt the information before sending any information to the control server.
It can be seen that, in the first embodiment of the present invention, the broadcast terminal plays the audio file to be played by receiving the play task information sent by the control server, and according to the start play time and the play period of the audio file to be played by the broadcast terminal, which are included in the play task information, where the broadcast terminal can receive the play task information sent by the control server before the start play time of the audio file, so that the requirement on the IP bandwidth of the control server can be reduced under the condition that the broadcast terminal is ensured to smoothly play the audio file to be played, thereby reducing the operation investment of the user on the bandwidth, and reducing the operation cost of the user.
