Embodiment 1

[0049] The implementation process of the streaming media download method in the embodiment of the present invention is as follows: figure 1 shown, including the following steps:

[0050] Step 101: the client obtains the Uniform Resource Locator (URL) address of the streaming media source file to be downloaded from the streaming media server; sends the Real-time Streaming Protocol (RTSP Describe) request carrying the URL address to the media server; receives the Rtsp description After the response (Rtsp describe Respone), send the RTSP setup (Rtsp setup) command to the streaming media server; after receiving the RTSP setup response (Rtsp setupRespone), the streaming media session is established. The establishment of the streaming media session follows the requirements of the RTSP standard protocol.

[0051] Here, the streaming media source file can be downloaded while playing, that is, the streaming media data sent by the streaming media server is played, and the streaming med...

Embodiment 2

[0076] The implementation process of the second streaming media download method in the embodiment of the present invention is as follows: figure 2 shown, including the following steps:

[0077] Step 201: the client obtains the URL address of the streaming media source file from the streaming media server; sends the RTSP Describe request carrying the URL address to the media server; after receiving the Rtsp describe Respone response, sends the RTSP setting (Rtsp setup) to the streaming media server command; after receiving the Rtsp setupRespone response, the streaming media session is established. The establishment of the streaming media session complies with the requirements of the RTSP standard.

[0078] Step 202: the client sets the request time field in the Rtsp play, writes the start time and end time of the selected download part in the streaming media source file into the request time field, and sends the Rtsp play to the streaming media server; here The transmission ...
