Claims9
A remote control system for effecting selective execution by remote control of any one of a plurality of functions of an apparatus connected to a communication line of the type permitting bidirectional communications comprising:
- first means for sequentially generating a plurality of voice signals representing questioning speeches each relating to respective ones of said functions of said apparatus and for transmitting said signals to a calling party over said communication line;
- second means for placing said first means in a stand-by-state for only a predetermined period of time to wait for arrival of a remote control signal transmitted from said calling party after transmission of each of said signals representing said questioning speeches and for automatically enabling said first means after expiration of said predetermined period of time to cause said first means to generate the next voice signal;
- third means for detecting transmission of a common remote control signal on said communication line from said calling party in response to any signal representing one of said functions transmitted to said calling party from said first means;
- and
- fourth means for executing said one function when said remote control signal responding to said signal representing said one function is detected by said third means.
A remote control system for effecting selective execution of any one of a plurality of functions of an apparatus by remote control over a telephone line comprising:
- first means for reproducing a pre-recorded outgoing message and for transmitting said message to a calling party on said telephone line when a communication request is received over said telephone line from said calling party;
- recording means for recording an incoming message transmitted from said calling party on said telephone line after transmission of said outgoing message;
- second means for checking to identify whether said calling party is authorized to use said apparatus;
- third means for sequentially generating voice signals representing questioning speeches each relating to respective ones of said functions of said apparatus and for transmitting said signals to said calling party over said telephone line when said calling party is identified as being authorized to use said apparatus;
- stand-by means for placing said third means in a stand-by state for a predetermined period of time to wait for arrival of a remote control signal from said calling party after transmission of each of said signals representing said questioning speeches;
- detecting means for detecting transmission of a remote control signal on said telephone line from said calling party in response to a signal representing one of said functions transmitted to said calling party from said third means;
- and
- fourth means for executing said one function when said remote control signal responding to said signal representing said one function is detected by said detecting means.
