SHOWPIECE GUIDE SYSTEM, METHOD AND SUBCONTENT DELIVERY SYSTEM

摘要

When an IC tag (61) owned by an IC tag owner in a delivery area (70) set in the vicinity of a video information reproducer (20) is detected, a reader/writer (30) transmits the user ID of all users belonging to the group (50) of the IC tag owner to a sound information delivery server (10) according to a user ID acquired from the IC tag (61). The sound information delivery server (10) monitors a user (51) entering and exiting the delivery area (70), by making of the user ID sent from the reader/writer (30) and delivers sound information to the PDA (60) of a user (51) who is considered to have entered the delivery area (70) according to the elapsed time of video information reproduced by the video information reproducer (20). Consequently, a showpiece guide system which can deliver a subcontent to all users in a group who came to the vicinity of the showpiece in synchronism with reproduction of a main content describing the content of the showpiece, is provided.
