Program recording reservation system and remote controller

Abstract

A program recording reservation system includes a recording apparatus includes a recorder for recording a broadcast program and a remote controller for making a recording reservation. A content management section manages an average recording bit rate for several recording modes and the remaining recordable capacity of the recorder. Date and time at which a broadcast program is broadcast are obtained, and a recording capacity necessary for recording a corresponding program is computed. On the basis of the average recording bit rate for each recording, the duration of the broadcast program, and the remaining recordable capacity is determined. The capability, or incapability, of recording for each program is displayed in a program table.

1 . A program recording reservation system comprising:
 a recording apparatus including a recorder to record a broadcast program; and   a remote controller to make a recording reservation for the recording apparatus,   wherein there is provided a content management section to manage, as recording parameters, an average recording bit rate for each of a plurality of provided recording modes and the remaining recordable capacity of the recorder, date and time at which a plurality of broadcast programs are scheduled to be broadcast are obtained as program information, a necessary recording capacity necessary for recording a program shown in the program information is computed, on the basis of the average recording bit rate for each recording mode provided by the recorder, a broadcast duration, and the remaining recordable capacity of the recorder, capability or incapability of recording each of broadcast programs shown in the program information is determined, and the determined capability or incapability of recording for each broadcast program is displayed in the program table having the program information.   
     
     
         2 . The program recording reservation system according to  claim 1 , wherein there is provided a recording reservation list management section to manage recording reservation information of a broadcast program for which a recording reservation has been made in the recorder as a recording reservation list, and
 the recording reservation list is obtained from the recording reservation list management section,   a necessary recording capacity necessary to record all the programs that have been scheduled to be recorded is computed on the basis of the recording parameters for each program that has been scheduled to be recorded in the recording reservation list, and   capability or incapability of recording is determined for each program of the program information on the basis of the necessary recording capacity necessary for recording for each broadcast program displayed as the program table and the remaining recordable capacity obtained by subtracting the necessary recording capacity necessary for recording for the reservations from the remaining recordable capacity of the recorder.   
     
     
         3 . The program recording reservation system according to  claim 2 , wherein, when there are recording modes in which recording is possible on the basis of the determination result of the capability or incapability of recording, a recording mode having the highest quality among the provided recording modes is displayed in the program table for each program to be broadcast, and when there are no recording modes in which recording is possible, the fact that recording is not possible is displayed for each program to be broadcast in the program table. 
     
     
         4 . The program recording reservation system according to  claim 2 , wherein the recording parameters include the number of programs that can be recorded simultaneously in the same time period, and
 when the recording reservation list shows that an additional recording reservation in the same time period cannot be made due to a limitation on the number of programs that can be recorded simultaneously at the day and time at which a program that is scheduled to be recorded is to be broadcast, the recording capability or incapability determination section displays, for each of broadcast programs, the fact that a recording reservation cannot be made for a program whose broadcast scheduled date and time overlap the scheduled date and time of the program that has been scheduled to be recorded, or the fact that the entire program cannot be recorded even if a recording reservation is made.   
     
     
         5 . The program recording reservation system according to  claim 3 , wherein the results determined by the recording capability or incapability determination section are displayed in the program table in such a manner as to be color-coded for each broadcast program. 
     
     
         6 . The program recording reservation system according to  claim 3 , wherein the results determined by the recording capability or incapability determination section are displayed in the program table in such a manner that a predetermined identifier is attached for each broadcast program. 
     
     
         7 . A remote controller capable of setting a recording reservation to a recording apparatus for allowing a content management section to manage an average recording bit rate for each of a plurality of recording modes and the remaining recordable capacity of a recorder as recording parameters and for recording a broadcast program in the recorder, the remote controller comprising:
 a parameter obtaining section to obtain a recording parameter from the content management section of the recording apparatus;   a program information obtaining section to obtain broadcast scheduled date and time of a plurality of broadcast programs as program information;   a recording capability or incapability determination section to compute a necessary recording capacity necessary to record each of the plurality of broadcast programs shown in the program information on the basis of the recording parameters for each broadcast program and to make a determination as to the capability or incapability of recording of each of the broadcast programs shown in the program information on the basis of the average recording bit rate for each recording mode provided in the recorder, a broadcast duration, and the remaining recordable capacity of the recorder; and   a display section to display the determined capability or incapability of recording for each broadcast program in the program table having the program information.
