The mobile terminal includes: a network communication unit 11 for communicating with the network, a storage unit 12 for storing media streams and short messages, a media player 13 with a video decoding unit 131, and a short message browser 14 for displaying The display unit 15 for video and short messages, these components and units are connected to the control unit 10 through the bus, and the control unit 10 coordinates the work of each unit and components through the bus. In addition, it also includes an input unit 16 connected to the bus, which is used to receive instructions from the user and provide communication between the user and the mobile terminal.

The processing procedure of the mobile terminal after receiving the short message when using the streaming media service is as shown in Figure 2:

1-2. The network communication unit receives the media stream data and stores it in the storage unit;

3. The media player reads the media stream data from the storage unit;

4. The video decoding unit of the media player decodes the media stream data to obtain a video signal;

5. The media player plays the video signal on the screen through the display unit;

6-7. The network communication unit receives the short message, stores it in the storage unit, and prompts the user with sound and/or display;

8. The user operates the mobile terminal to close the media player or switch the media player to the background, the specific implementation method depends on the mobile terminal;

9. The user operates the mobile terminal to start the short message browser;

10. The short message browser reads the short message from the storage unit;

11. The short message browser displays the short message on the screen through the display unit.
