SYSTEM FOR MANAGING ENCRYPTED CODE, DATA PROCESSOR AND ELECTRONIC APPARATUS

摘要

After receiving and storing the ID code A of an AV data transmitter (3), a remote controller (5) for managing ID receives the ID code A or B of any one of AV data receiver 4a or 4b. When the ID code A of the AV data receiver 4a is received, connectibility of communication is confirmed because the ID codes coincide with each other. When the ID code B of the AV data receiver 4b is received, nonconnectibility of communication is confirmed because the ID codes do not coincide with each other.
