Cradle, receiving terminal and receiving method

Abstract

When a portable receiving terminal is mounted on a cradle in an automobile, the satellite broadcasted contents is received by use of external antennas connected to the cradle, in place of built-in antennas contained in the portable receiving terminal. Accordingly, by use of the portable receiving terminal of the present invention, the satellite broadcasted contents can be surely received even in an automobile. Furthermore, the received information outputted from the portable receiving terminal can be transmitted to external devices such as car navigation system and the like when being mounted on the automobile. Accordingly, by taking advantages of a car navigation system, a car television and a car stereo mounted on the automobile, the information received by the portable receiving terminal can be displayed in a very lively manner.

       19 . A broadcast receiving system that receives a broadcast signal broadcasted from a broadcast station, comprising: 
 a receiving terminal; and    a cradle,    wherein the receiving terminal has:    a built-in antenna for receiving the broadcast signal broadcasted from the broadcast station;    first input means for inputting the broadcast signal from the cradle;    reproducing means for reproducing the broadcast signal that either being received by the built-in antenna or being inputted by the first input means; and    a power source supplying portion, having a battery, which supplies power to the receiving terminal,    wherein the cradle has:    a mounting portion on which the receiving terminal is detachably mounted;    an external antenna for receiving the broadcast signal broadcasted from the broadcast station;    first output means for outputting the broadcast signal received by the external antenna to the first input means of the receiving terminal;    a power source input portion connected to an external power source;    a power source output portion for outputting the power inputted by the power source input portion to the power source supplying portion of the receiving terminal;    first shifting means for shifting the reproducing means of the receiving terminal from a first mode to a second mode when the receiving terminal is mounted on the mounting portion, the first mode being for reproducing the broadcast signal received by the built-in antenna, the second mode being for reproducing the broadcast signal received by the external antenna and inputted by the first input means;    second shifting means for shifting the power source supplying portion of the receiving terminal from a third mode to a fourth mode when the receiving terminal is mounted on the mounting portion; the third mode being for supplying the power through the battery, the fourth mode being for supplying the power through the power source output portion.    
   
   
       20 . The broadcast receiving system as set forth in  claim 19 , 
 wherein second shifting means causes the power source supplying portion of the receiving terminal to charge the battery through the power source output portion while supplying the power through the power source output portion in the fourth mode.    
   
   
       21 . The broadcast receiving system as set forth in  claim 19 , 
 wherein the cradle has:    second input means for inputting the broadcast signal reproduced by the reproducing means of the receiving terminal; and    second output means for outputting the broadcast signal inputted by the second input means to an external device having a first display portion,    wherein the receiving terminal has:    a second display portion for displaying the broadcast signal reproduced by the reproducing means;    third output means for outputting the broadcast signal reproduced by the reproducing means to the second input means of the cradle; and    display control means for causing a first screen for having an user choose between a fifth mode and a sixth mode to be displayed on the second display portion of the receiving terminal when the receiving terminal is mounted on the mounting portion, the fifth mode being for outputting the reproduced broadcast signal to the second input means of the cradle by the third output means and for displaying the outputted reproduced broadcast signal on the first display portion of the external device, the sixth mode being for displaying the reproduced signal on the second display portion of the receiving terminal.    
   
   
       22 . The receiving system as set forth in  claim 21 , 
 wherein the external device is a car navigation system,    wherein the display control means of the receiving terminal causes the reproduced broadcast signal to be displayed on the first display portion of the external device and a second screen that allows the user to input an operation necessary for the reproduced broadcast signal to be displayed on the second display portion in the fifth mode, and causes the reproduced broadcast signal to be displayed on the second display portion and a third screen for car navigation to be displayed on the first display portion of the external device in the sixth mode.    
   
   
       23 . A receiving terminal which is capable of being detachably mounted on a mounting portion of a cradle having an external antenna for receiving a broadcast signal broadcasted from the broadcast station, first output means for outputting the broadcast signal received by the external antenna to the receiving terminal, a power source input portion connected to an external power source, and a power source output portion for outputting the power inputted by the power source input portion to the receiving terminal, comprising: 
 a built-in antenna for receiving the broadcast signal broadcasted from the broadcast station;    first input means for inputting the broadcast signal from the first output means of the cradle;    reproducing means for reproducing the broadcast signal that either being received by the built-in antenna or being inputted by the first input means;    a power source supplying portion, having a battery, which supplies power to the receiving terminal through either the battery or the power source output portion of the cradle;    first shifting means for shifting the reproducing means from a first mode to a second mode when the receiving terminal is mounted on the mounting portion, the first mode being for reproducing the broadcast signal received by the built-in antenna, the second mode being for reproducing the broadcast signal received by the external antenna of the cradle and inputted by the first input means; and    second shifting means for shifting the power source supplying portion from a third mode to a fourth mode when the receiving terminal is mounted on the mounting portion; the third mode being for supplying the power through the battery, the fourth mode being for supplying the power through the power source output portion of the cradle.    
   
   
       24 . The receiving terminal as set forth in  claim 23 , 
 wherein second shifting means causes the power source supplying portion to charge the battery through the power source output portion of the cradle while supplying the power through the power source output portion in the fourth mode.    
   
   
       25 . The receiving terminal as set forth in  claim 23 , 
 wherein the cradle has:    second input means for inputting the broadcast signal reproduced by the reproducing means of the receiving terminal; and    second output means for outputting the broadcast signal inputted by the second input means to an external device having a first display portion,    the receiving terminal further comprising:    a second display portion for displaying the broadcast signal reproduced by the reproducing means;    third output means for outputting the broadcast signal reproduced by the reproducing means to the second input means of the cradle; and    display control means for causing a first screen for having an user choose between a fifth mode and a sixth mode to be displayed on the second display portion when the receiving terminal is mounted on the mounting portion, the fifth mode being for outputting the reproduced broadcast signal to the second input means of the cradle by the third output means and for displaying the outputted reproduced broadcast signal on the first display portion of the external device, the sixth mode being for displaying the reproduced signal on the second display portion of the receiving terminal.
