The method comprises the steps of running a live broadcast application on the mobile terminal, rendering a graphical User Interface (UI) on a touch display screen of the mobile terminal, wherein live broadcast video pictures can be contained in the UI, the live broadcast video pictures can be displayed in a full screen mode or not, and users can watch the live broadcast video pictures on the mobile terminal. The graphic user interface can also comprise a bullet screen input box and a determination control, a user can issue bullet screen data through the bullet screen input box and the determination control, and the server displays the bullet screen data on the graphic user interface in real time after receiving the bullet screen data sent by the user.
Because the barrage data displayed on the graphical user interface has real-time performance, in the embodiment of the invention, if a user needs to check the historical barrage data to perform operations such as reply, approval, comment and the like on the historical barrage data, the trigger operation can be performed on the display screen of the mobile terminal, and the mobile terminal can detect the trigger operation acting on the display screen of the mobile terminal and send the trigger operation to the live application. Specifically, the triggering operation may be an operation for triggering the backtracking of the historical bullet screen data, for example, the triggering operation is an operation of pressing a bullet screen region for a long time or an operation of touching a preset control, the bullet screen region may be a region where the bullet screen is displayed on the graphical user interface, and the preset control may be a preset control for triggering the backtracking of the historical bullet screen data.

| periodic time period | Inclination data | Barrage text |
| 1 | A | a |
| 2 | B | b |
| 3 | C | c |
