Abstract: A message reminding method and a terminal device are provided. The method includes: A first application receives a first message sent by a second application. The first message includes an identifier of the second application. The second application is an application that receives a new message. The first application and the second application are applications in a system carried by a simulator. The first application sends a second message to a simulator application. The second message includes the identifier of the second application. The second message indicates the simulator to determine whether to perform reminding on the new message received by the second application. According to the method, reminding may be implemented when an application in the simulator receives a new message, so that a user can view and process the message.

Abstract: This application discloses a data flow control method and apparatus. The method includes: calculating, by a device when a clock signal arrives, a quantity of transition-minimized differential signaling (TMDS) characters currently stored in a buffer of the device; and outputting, by the device, the TMDS character in the buffer when the quantity of TMDS characters currently stored in the buffer reaches a preset value, or outputting a gap data packet when the quantity of TMDS characters currently stored in the buffer does not reach a preset value, where the preset value is less than or equal to a TMDS character storage capacity of the buffer.
