Cell phone and program for controlling broadcast receiving function of cell phone

Abstract

The cell phone has a plurality of batteries for supplying power according to their use. When the power of a battery is nearly depleted while the user is viewing a TV program, the cell phone informs the user of that fact to restrict the viewing of the TV program.

What is claimed is:  
     
         1 . A cell phone comprising: 
 a radio communication transceiver/receiver unit which transmits and receives speech or data by radio;    a broadcast receiver which receives broadcast waves such as of a TV broadcast;    a power supply unit which supplies power to each of the radio communication transceiver/receiver unit and the broadcast receiver;    a plurality of batteries provided in the power supply unit;    a use management unit which manages the use of the plurality of batteries;    a power supply management unit which manages supply of power to the radio communication transceiver/receiver unit or the broadcast receiver according to the use managed by the use management unit ; a power supply monitoring unit which monitors the useful power level of the batteries;    an alarming unit which alarms the user that the power of a battery is nearly depleted while a broadcast is being received, the battery supplying power to the broadcast receiver; and    a power supply restricting unit which restricts the supply of power to the broadcast receiver after the alarm has been provided.    
     
     
         2 . The cell phone according to  claim 1 , further comprising a non-interrupt instructing unit which instructs to continue receiving a broadcast, wherein 
 the power supply restricting unit continues the supply of power to the broadcast receiver when the non-interrupt instructing unit instructs to continue receiving a broadcast after a useful battery power level has been nearly depleted.    
     
     
         3 . The cell phone according to  claim 1 , wherein 
 at least one of the plurality of batteries is used mainly for transmitting and receiving speech or data, the other of the plurality of batteries being used mainly for receiving broadcast waves.    
     
     
         4 . The cell phone according to  claim 1 , further comprising a TV viewing entry information storage unit which stores an operating condition of a function of restricting a receiving of broadcast waves when the useful battery power level has reached a predetermined value.  
     
     
         5 . The cell phone according to  claim 4 , wherein 
 the TV viewing entry information storage unit stores an ON or OFF operating condition of the function of restricting the receiving of broadcast waves.    
     
     
         6 . The cell phone according to  claim 4 , wherein 
 the TV viewing entry information storage unit stores the predetermined value.    
     
     
         7 . The cell phone according to  claim 4 , further comprising an input unit which receives, from outside, the operating condition of the function of restricting the receiving of broadcast waves, the operating condition being stored in the TV viewing entry information storage unit.  
     
     
         8 . The cell phone according to  claim 5 , further comprising an input unit which receives, from outside, the ON or OFF operating condition of the function of restricting the receiving of broadcast waves, the ON or OFF operating condition being stored in the TV viewing entry information storage unit.  
     
     
         9 . The cell phone according to  claim 6 , further comprising an input unit which receives, from outside, the threshold value stored in the TV viewing entry information storage unit.  
     
     
         10 . A program for controlling a broadcast receiving function of a cell phone, the cell phone having an radio communication transceiver/receiver unit which transmits and receives speech or data by radio and a broadcast receiver which receives broadcast waves such as of a TV broadcast, the program allowing the cell phone to serve as: 
 power supply means which supplies power to each of the radio communication transceiver/receiver unit and the broadcast receiver;    use management means which manages the use of a plurality of batteries provided in the power supply means;    power supply management means which manages supply of power to the radio communication transceiver/receiver unit or the broadcast receiver according to the use managed by the use management means;    power supply monitoring means which monitors the useful power level of the batteries;    alarming means which alarms the user that the useful power of a battery is nearly depleted while a broadcast is being received, the battery being supplying power to the broadcast receiver; and    power supply restricting means which restricts the supply of power to the broadcast receiver after the alarm has been provided.    
     
     
         11 . The program for controlling a broadcast receiving function of a cell phone according to  claim 10 , comprising non-interrupt instructing means which instructs to continue receiving a broadcast so as to allow power to be supplied to the broadcast receiver means when the non-interrupt instructing means instructs to continue receiving a broadcast when the useful power of the battery has been nearly depleted.
