image distribution server comprising:
a data storage unit for storing in advance the moving image data including information as to the decoding times and the reproducing
times for the video data and the audio data;

a phase adjustment variable storage unit for storing a predetermined phase adjustment variable; and
a first rewriter for reading said moving image data stored in said data storage unit, and changing the information included
therein as to the decoding times or the reproducing times based on said predetermined phase adjustment variable to adjust
the phase relationship between the video data and the audio data,

wherein said moving image data comprises an MPEG2-TS (Moving Picture Experts Group 2-Transport Stream) stream, and
wherein the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol is used for distributing said moving image data
