| Zusammenfassung: | A TV broadcast receiver measures, at least two times, a signal intensity in a maximum receiving direction and a signal intensity in the 180 degree opposite receiving direction among 16 receiving directions of a smart antenna. If the signal intensity in the maximum receiving direction is significantly different from that in the opposite receiving direction, it determines that the smart antenna is connected. If the signal intensity in the maximum receiving direction is substantially the same as that in the opposite receiving direction, it determines that the smart antenna is disconnected. It displays messages of the connection and disconnection of the smart antenna on a monitor.This makes it possible to quickly determine whether the antenna connected to the TV broadcast receiver is a smart antenna or a stationary unidirectional antenna. |
