A live data broadcast method is performed at a computer server that is communicatively coupled to a first terminal and a second terminal. The method includes: detecting, during live broadcast of content of a first application running in a foreground of the first terminal to the second terminal, that the first terminal switches the first application to run in a background of the second terminal; obtaining predetermined multimedia content associated with the live broadcast; sending instructions to the second terminal to play the predetermined multimedia content on the second terminal, the predetermined multimedia content being different from content of a second application running in the foreground; and communicating status updates related to the live broadcast with the first terminal and the second terminal, respectively.
