Abstract

The invention relates to a method for switch playing of two kinds of media in a vehicle-mounted entertainment system. The vehicle-mounted entertainment system includes a DirectShow used for constructing a playing framework, a memory used for storing playing information of different media and a disk file system. In an actual switch playing process, a WinCE file system is used for dynamically storing real-time playing information of the different media and then used for follow-up restoring use of the playing information of the media. The method for the switch playing of the two kinds of media in the vehicle-mounted entertainment system has a clear logical management hierarchy and is capable of realizing perfectly memory switch playing between at least two media.
