【発明の名称】ホームコントロール装置
Document Type and Number:
Japanese Patent JP2868303
Kind Code:
B2
Abstract:
PURPOSE:To realize a rational home controller by specifying a flag in a signal of security information and a flag in a signal of control information with different PN codes CONSTITUTION:Since a PN code is employed for a flag, a reception side monitors correlation between a PN code generated internally and a PN code of a reception signal and decodes the signal depending whether or not the correlation exceeds a threshold level so as to identify whether the received signal is a signal of security information or a signal of control information. Since flags F1, F2 are specified by a PN code having higher correlation against noise, the signal of security information or the signal of control information which have a different form are identified with high reliability in such a manner.
