COMMUNICATION SYSTEM, MOVING IMAGE REPRODUCTION APPARATUS, AND COMMENT INPUT AND OUTPUT TERMINAL

摘要

PROBLEM TO BE SOLVED: To enable comments over a moving image from plural viewers to be shared by the viewers while avoiding overloading on a comment management apparatus storing comment data expressing the comments.

SOLUTION: A moving image reproduction apparatus which reproduces a moving image distributed via a communication network executes: associating a comment inputted by the user with a time stamp expressing the input timing of the comment and storing the comment; transmitting the comment to the other moving image reproduction apparatuses; displaying the comment received via the communication network in synchronization with the reproduction of the moving image; and transmitting the stored comment and time stamp to the comment management apparatus at a transmission timing different from that of the other moving image reproduction apparatuses, after the finish of the reproduction of the moving image.
