Abstract

A method for playing an audio-video (AV) file is provided. The first AV file is played in a first or a second player. The first and the second players are coupled to one first digital media server. First, the first digital media server outputs a first AV file to the first player for playing the same. Next, the first player outputs a first pausing signal corresponding to the first AV file to the first digital media server. Then, the first digital media server pauses the first AV file and generates a first pausing data recording a first pausing time. Next, the second player outputs a pause-canceling signal to the first digital media server. When the pause-canceling signal corresponds to the first AV file, the first digital media server starts outputting the first AV file to the second player from the first pausing time.
