摘要： A television receiver is connected to a smart antenna, and comprises: a tuner for receiving, and measuring signal intensity of, a television signal; an OSD superimposer for superimposing, on the television signal, an image indicating an active receiving direction of the antenna; and a microprocessor for outputting, to the antenna and respective elements of the television receiver, various signals including a receiving direction control signal. Based on the signal intensity, the microprocessor determines the active receiving direction of the antenna, and outputs a receiving direction control signal to the antenna, and further outputs a signal indicating the active receiving direction of the antenna to the OSD superimposer which is connected to a monitor for image display. The antenna comprises: a control unit for making active one receiving direction commanded by the receiving direction control signal; and a display for displaying the commanded receiving direction. A user can easily recognize the receiving direction of the antenna, either at the television receiver site or the antenna site.

摘要： A digital/analog broadcast receiving device has either in a first setting mode (proficient mode) in which whole of setting items can be changed without any limitation and a second setting mode (beginner mode) in which the setting items can be changed with some limitation. The receiving device is set in the second setting mode at the time of shipment from a factory. On the screen displaying thereon a setting menu including setting items for a various operations, such a setting item that cannot be changed is not displayed or prevented from being selected. Thus, the menu items that are desired not to be touched by a beginner user etc. can be prevented from being displayed or selected, so as to improve the operability and also protect the settings.

摘要： 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.

摘要： A multi-directional antenna connected with a digital television broadcast signal receiver is arranged not to move one full turn instantaneously in response to an abrupt drop down in the intensity of a received signal thus to avoid any downward overshooting of the intensity of the received signal and eliminate any useless direction searching time while remains favorably controlled to face in the direction where the intensity of the received signal is at optimum. More specifically, the maximum of the intensity of a received signal at each channel is measured and the threshold is set to a level lower than the maximum. When the intensity of a received signal has dropped down from the threshold, the antenna remains not turned within a predetermined period of marginal time. The antenna is moved one full turn only when the intensity drops down from the threshold and stays continuously over the predetermined period of marginal time. Then, the maximum of the intensity of the received signal is modified and stored for future use.

摘要： A TV receiver preliminarily measures and stores, in a memory, data of best receiving directions, each giving maximum signal intensity, of a multi-directional antenna for receivable channels. When the antenna rotationally shifts physically for some reason, one channel is selected and subjected to measurements by an omni-directional scanning again to determine a new best receiving direction. A receiving direction number difference between the stored best receiving direction and the new best receiving direction of the same channel is determined. Using the receiving direction number difference for the one channel, all data stored in the memory are renewed at one time, the data being the best receiving direction numbers and the signal intensities therefor for all the channels. The antenna direction can be quickly adjusted to the rotational shift by new measurements for one channel, without requiring time to make unnecessary measurements for all channels, achieving a best receiving condition steadily.
