Abstract: A method and device for processing information are provided. The method includes: judging whether a screen-sharing request from a peer device is received via a wireless network transmission link; when it is judged that the screen-sharing request from the peer device is received, obtaining an Internet Protocol (IP) address and a port number of the peer device; generating, according to the IP address and the port number, a Uniform Resource Locator (URL) corresponding to media data that is used for playing screen content of the peer device; determining a standard player corresponding to the URL; and playing the media data corresponding to the URL using the standard player.

Abstract: A method and a device are provided for playing a multimedia file. The device sends a first audio data packet to an audio player device and sends a first video data packet to a video player device. The first audio data packet and the first video data packet both include a data test identifier. The device receives a first timestamp from the audio player device. The device receives a second timestamp from the video player device. The device then sends a second audio data packet and a second video data packet respectively to the audio player device and the video player device according to the first timestamp and the second timestamp. Thus, the audio player device and the video player device play synchronously the second audio data packet and the second video data packet.
