<p>A video reproducing apparatus (120) wirelessly transmits, to a server apparatus (100), reproduction estimated-time information (TT1) obtained by adding a processing time (t1) to the time data (T1) of video data. An audio reproducing apparatus (110) wirelessly transmits, to the server apparatus (100), reproduction estimated-time information (TT2) obtained by adding a processing time (t2) to the time data (T2) of audio data. The server apparatus (100) wirelessly receives the reproduction estimated-time information (TT1,TT2), and calculates and wirelessly transmits reproduction estimated-time difference information (?t) thereof. The video reproducing apparatus (120) controls, based on the reproduction estimated-time difference information (?t), the time at which to reproduce the video data such that the video is reproduced substantially in synchronism with the audio. The audio reproducing apparatus (110) controls, based on the reproduction estimated-time difference information (?t), the time at which to reproduce the audio data such that the video is reproduced substantially in synchronism with the audio.</p> |
