The above operations are performed by a terminal side, and the download terminal may be a mobile terminal, such as a mobile phone terminal, or a fixed terminal such as a computer.
Preferably, the determining, by the downloading terminal, the film source information of the streaming media file includes:
in the process of ordering the streaming media, the downloading terminal acquires the film source information of the currently ordered streaming media file from the streaming media ordering server, wherein the film source information includes an identifier of the streaming media file, such as a name of the streaming media file, and file directory information of the streaming media file stored in the streaming media ordering server.
Preferably, the download address of the streaming media file is a download address of the streaming media file generated after the subscription management server obtains the streaming media file from the streaming media on-demand server according to the piece source information of the streaming media file carried in the download request after receiving the download request.
Preferably, the acquiring, by the download terminal, a download address of the streaming media file generated by the subscription management server according to the film source information includes:
and directly sending the generated download address of the streaming media file to the download terminal by the order management server. Or,
sending the download address of the generated streaming media file to a push server by the order management server;
and the push server forwards the data to the lower terminal.
That is to say, the order management server receives a download request sent by a terminal, acquires the piece source information of the streaming media file from the download request, acquires the streaming media file from the streaming media on-demand server according to the piece source information, stores the streaming media file in a preset temporary file, generates a download address of the streaming media file, and then sends the download address to the terminal, and the download address can be directly sent to the terminal or can be forwarded to the terminal through other servers; and subsequently, providing the streaming media file to the terminal according to the terminal request.
Preferably, the terminal obtains a download address of the streaming media file, and includes:
receiving a Push message sent by a Push (Push) server, wherein the Push message carries a download address of a streaming media file;
and sending the download address of the streaming media file carried in the push message to the push server by the subscription management server. Namely, the push server forwards the download address of the streaming media file to the terminal.
Preferably, the download address of the streaming media file includes:
the IP address of the subscription management server, the directory information of the temporary file of the stream media file stored on the subscription management server and the identification of the stream media file.
In the embodiment of the invention, a new subscription option is added in a stream media player menu at a terminal side, a user sends a downloading request by selecting the option in the process of ordering the stream media, and if the user is not in an on-demand state, the subscription option is grayed, namely is not selectable.
