Abstract
Abstract A program reserving apparatus of a VTR capable of receiving teletext data carries out recording reservation of a program to be broadcasted by using a program list out of the received teletext data. When recording is reserved, time data of the program to be reserved selected by an operator are stored in a reservation data work memory (12c) and are displayed on the same screen as the program list. When 4 digits of numeral data other than the time data are erroneously taken as the end time in the reservation data work memory, the present end time can be changed to the next time data by operating a cursor key (11b-1) of a remote control transmitter (11b). Then, by operating an OK key (11b-3) of the remotecontrol transmitter, the reservation data in the reservation data work memory are transferred to a reservation data memory (19).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
312 words
A program reserving apparatus in a video tape recorder capable of receiving teletext data transmitted multiplexed in a vertical blanking period of television video signals, said program reserving apparatus being capable of taking at least time data related to a program to be put on the air out of said received teletext data to utilize the same for recording reservation of said program to be put on the air, said time data including at least broadcasting start time and broadcasting end time, said program reserving apparatus comprising: key input means (11) including a key for instructing recording reservation; teletext control means (21, 10, 6, 12a) for extracting and decoding reservation data including at least said time data out of said teletext data; and first storing means (12b) for storing said extracted and decoded time data, said teletext controlling means extracting time data related to programs to be put on the air to be reserved for recording, program by program, from said first storing means in response to an instruction from said key input means; said program reserving apparatus further comprising: second storing means (12c) for storing, program by program, the time data related to the programs to be put on the air to be reserved for recording extracted from said first storing means by said teletext controlling means; and third storing means (19) for storing time data related to all the programs to be put on the air to be reserved for recording, said teletext controlling means extracting the time data stored in said second storing means to transfer the same to said third storing means in response to the instruction from said key input means; wherein said teletext controlling means changes broadcasting end time out of the time data stored in said second storing means by an operation of said key for instructing recording reservation out of said key input means.
Claim 2
Dependent Claim
312 words
A program reserving apparatus in a video tape recorder capable of receiving teletext data transmitted multiplexed in a vertical blanking period of television video signals, said program reserving apparatus being capable of taking at least time data related to a program to be put on the air out of said received teletext data to utilize the same for recording reservation of said program to be put on the air, said time data including at least broadcasting start time and broadcasting end time, said program reserving apparatus comprising: key input means (11) including a key for instructing recording reservation; teletext control means (21, 10, 6, 12a) for extracting and decoding reservation data including at least said time data out of said teletext data; and first storing means (12b) for storing said extracted and decoded time data, said teletext controlling means extracting time data related to programs to be put on the air to be reserved for recording, program by program, from said first storing means in response to an instruction from said key input means; said program reserving apparatus further comprising: second storing means (12c) for storing, program by program, the time data related to the programs to be put on the air to be reserved for recording extracted from said first storing means by said teletext controlling means; and third storing means (19) for storing time data related to all the programs to be put on the air to be reserved for recording, said teletext controlling means extracting the time data stored in said second storing means to transfer the same to said third storing means in response to the instruction from said key input means; wherein said teletext controlling means changes broadcasting end time out of the time data stored in said second storing means by an operation of said key for instructing recording reservation out of said key input means.
Claim 3
Dependent Claim
103 words
A program reserving apparatus according to claim 1, wherein said teletext controlling means comprises: teletext decoder means (21) for extracting reservation data including at least said time data out of said teletext data; picture data memory (10) for holding said reservation data extracted by said teletext decoder means; classifying means (6b, 12a) for classifying figures constituting time data out of the reservation data stored in said picture data memory; decoding means (6c) for decoding said classified time data; and a teletext controlling circuit (6c) for controlling operations of said teletext decoder means, said picture data memory, said classifying means and said decoding means.
Claim 4
Dependent Claim
26 words
A program reserving apparatus according to claim 1, wherein said key for instructing recording reservation is a cursor key (11b-1) of a remote control transmitter (11b).
Claim 5
Dependent Claim
22 words
A program reserving apparatus according to claim 3, wherein said broadcasting end time is changed by one operation of said cursor key.
Claim 6
Dependent Claim
30 words
A program reserving apparatus according to claim 1, wherein said key for instructing recording reservation is a cursor key of a key board (11a) provided on said video tape recorder.
Claim 7
Dependent Claim
21 words
A program reserving apparatus according to claim 5, wherein said broadcasting time is changed by one operation of said cursor key.
Claim 8
Dependent Claim
35 words
A program reserving apparatus according to claim 1, wherein said teletext controlling means further comprises means for displaying the time data stored in the second storing means (12c) on a screen of a display apparatus.
Claim 9
Dependent Claim
92 words
