Abstract
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.
Claims39
An encryption code management system for use in a plurality of communication systems composed of a plurality of data processors that exchange data encrypted with specific encryption codes,
- wherein there is provided an electronic apparatus including:
- a code management reception portion that receives the encryption codes of the data processors;
- a code management control portion that compares a plurality of the encryption codes received by the code management reception portion;
- and
- a result output portion that outputs a comparison result yielded by the code management control portion, and
- wherein the data processors include a code management transmission portion that transmits the encryption codes of the data processors themselves to the electronic apparatus.
