摘要:
The flight exercise without an assistant can be achieved and the risk, generated from a mistaken operation in the flight exercise is reduced. Prescribed performance titles or music is recorded in a recording mode, and the recorded sound is reproduced in a playback mode. Accordingly, it is possible to practice flights to the sound. Further, when a model airplane is not properly manipulated, the mistaken operation can be alarmed.

A VCR includes apparatus for controlling a cable converter unit. In a preferred embodiment, infrared (IR) transmission of commands from the VCR to the cable converter unit is employed. An LED assembly holds the LEDs in a predetermined orientation and provides first and second IR ports through which different amounts of IR signals are transmitted.

A device for optimizing antenna operation comprises a wireless control signal detector for detecting a wireless control signal generated by a remote control unit, and a microprocessor operatively connected to the detector. The microprocessor is programmed to analyze the wireless control signal during a learning operation to determine a coding format of the wireless control signal and to analyze the wireless control signal during a normal use operation to determine a broadcast channel or station selected by a user. The device additionally comprises a plurality of tuning elements operatively connectable to an antenna for tuning the antenna, and a plurality of switching circuits operatively connected to the tuning elements and to the microprocessor. The switching circuits are operable to selectively couple the tuning elements to the antenna, in response to signals from the microprocessor, thereby optimizing signal reception by the antenna for a channel or station selection encoded in the wireless control signal.

A VCR includes circuitry for controlling a cable converter unit, circuitry for detecting the presence of a television signal, and control code transmission circuitry for remotely controlling a cable converter unit. Advantageously, because the VCR is coupled to the output of the cable converter unit, the VCR can monitor the television signals received from the cable converter unit to ensure that commands sent to the cable converter unit from the VCR are executed. It is herein recognized that a skip list programmed into a VCR may be used by the VCR to control a cable box. That is, in response to a channel up command received by the VCR, the VCR would not change channels itself, but rather controls the cable box to select the next preferred channel entered in the skip list of the VCR. In this mode of operation, the channel tuning keys (e.g., CHAN UP, CHAN DN) of the VCR remote control are used to control an external source of signals, while the VCR mechanism control keys (e.g., PLAY, STOP, RECORD, FAST FORWARD) control the operation of the VCR.

A VCR controls a cable box, and monitors television signals received from the cable box in a "closed loop" manner. By monitoring an appropriate signal the controller of the VCR can detect perturbations of signal level which indicate that the cable box has changed channels. That is, the output signal of the cable box remodulated on, for example, the RF carrier frequency of channel 3, will be momentarily lost during the period in which the cable box changes channels. Thus, the subject apparatus can determine if the cable box is "off" or "on" by issuing a channel change command and observing if the cable box responds to the channel change command. In one embodiment of the invention the VCR causes an on-screen display of an error message if it determines that it is unable to control the came box.
