SMART ANTENNA SYSTEM, FAILURE DETECTION METHOD FOR THE SAME, AND BROADCAST RECEIVING SYSTEM

摘要

PROBLEM TO BE SOLVED: To detect a failure in an antenna body in a smart antenna system for changing directivity to maintain an optimum reception state.;SOLUTION: The antenna body 100 has: a reception confirming section for transmitting a recognition signal indicating the reception of a control signal to a control section 40 when the control signal is transmitted from the control section 40; a failure determination section for determining that the antenna body 100 has failed when the reception confirming section does not receive the cognitive signal; and a failure informing section for informing the failure state of the antenna body, based on a result determined by the failure determination section.;COPYRIGHT: (C)2009,JPO&INPIT
