BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video tape recorder capable of receiving teletext broadcasting, for example, PDC.
The present invention relates to a video tape recorder capable of series recording reservation and recording execution by (Programmme Delivery Control System).

[0002]

2. Description of the Related Art In recent years, as a recording reservation method for video tape recorders (hereinafter referred to as VTRs) in Europe, a program table broadcast as a part of a teletext broadcasting service, that is, a broadcast date and a broadcast start time of scheduled broadcast programs. , V using information (teletext data) such as program title
PT (Video Programming by Teletext) is used. In VPT, a program guide superimposed on a vertical blanking period of a television video signal sent from a broadcasting station is displayed on the display, and the operator can designate a desired reserved program with a cursor while viewing this display. This is a system for retrieving data necessary for recording reservation to make a program reservation, and by doing so, the number of key scans required for program reservation can be greatly reduced. Such a recording method is proposed in the former West German Published Specification No. 3335082.

Further, there is a VPS (Video Program Sysyem) capable of accurately recording even if a reserved program changes in time.
It is conducted mainly in Germany. The VPS designates a program broadcast code (VPS code) superimposed in the vertical blanking period of a television video signal sent from a broadcasting station, so that a desired reservation can be made without being restricted by the program start reservation time. It is a program reservation system for recording a program. The VPS code is a code assigned to each program, and by designating this code, the VTR becomes a VP.
Recording can be performed by recognizing the S code, and the desired program can be accurately recorded even if the reserved program has a time change.

On the other hand, in the United Kingdom, the above-mentioned VPT and VP
PDC (Programme Delivery Contr
ol Ststem) has been implemented by channel 4 since March 1992. PDC is a ghost of FASTEXT, which is one of the teletext broadcasting systems used in the United Kingdom.
Recording reservation data and recording execution data (P
This is a system for transmitting a DC code). The PDC code includes date code, series code, and the like. The series code is a code assigned to a continuous program or a program genre such as sports or news. By specifying a series code and making a recording reservation, a continuous program or a program of the same genre is recorded without re-reservation. be able to.

By the way, the recording reservation by the above-mentioned VPT,
A program title is recorded at the time of program recording reservation so that the user can easily select a desired program at the time of reproduction when the teletext data is fetched and reserved recording is performed using a VTR capable of executing operation. ing. The user inputs this program title by an insert operation, but this operation requires labor and time, and sometimes an erroneous input occurs. In order to solve this, the applicant has changed the program title data in the teletext data to
We proposed a method to capture the data as recording reservation data (Japanese Utility Model Publication No. 3-53086). By this method, the operation of inputting the program title is simplified and erroneous input does not occur.

[0006]

However, when the series code is designated by using the VTR capable of series recording reservation and execution operation by the above-mentioned PDC code and, for example, reserved recording and reproduction of a continuous program, the user can Although the program title can be determined, there was a problem that it was not possible to determine how many times the series was recorded.

Further, when recording reservation data including a recording start date and time is stored in a storage means to reserve a program having a series code, and a series recording reservation is made, in order to prevent omission of the series recording, a VTR is recorded. Stipulates that the recording reservation data must be retained for four weeks from the date of recording. Therefore, there is a problem that the VTR needs to be provided with another storage means for storing the recording execution date and time when the series recording was last executed.

The present invention has been made in view of the above circumstances, and a first aspect of the present invention is to provide a video tape recorder which is provided with a means for storing the number of times of series recording, and can record the number of times with a program. According to the second aspect of the present invention, by providing a means for rewriting the recording start date and time in the series recording reservation data to the recording execution date and time, the storage means for storing the date when the series recording is executed is for storing the recording reservation data. It is an object of the present invention to provide a video tape recorder which is shared with the above-mentioned storage means.

[0009]

A video tape recorder according to a first aspect of the present invention includes a series code common to a series of programs having continuity or association, which are superimposed on a vertical blanking period of a television video signal.

Further, the teletext control unit 6 judges whether the executed recording reservation is a series reservation (step S25). If the recording reservation is a series reservation, the teletext control unit 6 makes the series of the reservation data memory 16 series. The number of series recording executions stored in the recording execution count storage unit 16a is
It is rewritten to a numerical value obtained by adding 1 to the current state (step S26). At the same time, the teletext control unit 6 writes the series recording execution count read from the reserved data memory 16 into the screen memory 9, converts this into a character signal by the teletext decoder 7, and gives it to the display / recording output switching circuit 5. The series recording execution count is recorded together with the program title and displayed on a display screen (not shown).

In this embodiment, the recording time of the program title and the number of times of series recording is set to be a fixed time from the start of the timer recording. This fixed time is VTR
The control unit 13 counts (step S28), and after a certain period of time, the teletext decoder 7 erases the program title and the series recording execution count from the screen memory 9 in response to a command from the VTR control unit 13 (step S29). . If the recording reservation executed in step S25 is not a series reservation, the title is displayed and then the VTR controller 13 counts a certain time (step S28) and this display is erased (step S28). S29). Then, the switching signal a is input from the teletext control unit 6 to the display / recording switching circuit 5, and the recording signal input to the display / recording switching circuit 5 is changed to
The video signal b from the video signal processing circuit 4 is switched to, and the recording of the program title and the number of times of series recording is completed (step S30). In step S22, when the title recording is not reserved as the recording reservation information, the recording signal input to the display / recording switching circuit 5 is the video signal b from the video signal processing circuit 4.

FIG. 3 is a schematic diagram showing a screen to be recorded when a series recording reservation is made and a program title and the number of series recording executions are recorded. The program title 200 and the number of series recording executions are displayed on the television screen 100. 300 and 300 are inserted in the form of superimpose.

By the above operation, the VTR of this embodiment is
Can record the number of times the series recording is executed together with the TV image and the program title when the series recording is executed.

The recording reservation data is written in. The teletext control unit 6 determines whether the VTR is in a standby recording standby state,
It is determined whether the reserved recording is being executed or not (step S51). When the reserved recording is on standby or the reserved recording is being executed, a command is sent to the teletext decoder 7 to display the screen memory 9 The PDC code in the ghost row is read from (step S52), and the PTR code is sent to the VTR controller 13.
The DC code is supplied (step S53). And VT
When R is on standby for reserved recording or is executing reserved recording,
The same operation is repeated thereafter. If it is determined in step S51 that the recording is not on standby for reserved recording or executing reserved recording, these operations are ended.

Next, the operation of the VTR controller 13 will be described with reference to FIGS. 4 and 6. The VTR control unit 13 determines whether or not the PDC code is given from the teletext control unit 6 (step S61), and if it is given, determines whether or not the VTR is in a state of waiting for reserved recording (step S61). S62). If the VTR is in the reserved recording standby state, a check is made as to whether or not the reserved recording of the first reserved data is started by an operation described later (step S63), and it is determined whether or not the reserved recording is started ( Step S64),
If it has not started, it is determined whether all the recording reservation data have been collated (step S65). When the reserved recording is started, the process returns to step S61 and it is determined whether the PDC code is given. If it is determined in step S65 that all the recording reservation data have not been collated, it is collated by the operation described later to determine whether or not the reservation recording of the next reservation data is started (step S66), and the process returns to step S64. Then, it is verified again whether or not the reserved recording of all the reservation data is started, and if this verification is completed, the process returns to step S61. After that, this operation is repeated.

If it is determined in step S62 that the reserved recording is not in the standby state, it is determined whether the reserved recording is being executed (step S67). If the reserved recording is being executed, the completion of the reserved recording is checked. Is performed by the operation described later (step S68), the process returns to step S61, it is determined whether the PDC code is given, and this is repeated thereafter. If it is determined in step S67 that reserved recording is not being executed, the process also returns to step S61.

Next, with reference to FIGS. 4 and 7, the operation performed by the VTR controller 13 in the case of collating the recording reservation data in step S63 or step S66 in FIG. 6 will be described. When the PDC code is supplied to the VTR control unit 13 and the VTR is in the standby recording standby state, the VTR control unit 13 first determines whether the recording reservation data to be collated is series-reserved ( Step S7
1) If the series is reserved, it is determined whether or not the series code in the PDC code supplied from the teletext control unit 6 matches the series code of the recording reservation data (step S72). If the two match, a command to rewrite the recording start date, month and start time of the recording reservation data to the date and time indicated by the clock of this VTR is sent to the stored data update unit 17, and the stored data update unit 17 is sent.
Rewrites the recording preliminary data in the reserved data memory 16 (step S73), starts reserved recording (step S74), and finishes the operation related to the verification of reserved recording start. If it is determined in step S72 that the series code in the PDC code and the series code in the recording reservation data do not match, the operation relating to the start of reserved recording is ended.

When it is determined in step S71 in FIG. 7 that the recording reservation data to be collated is not series-reserved, it is determined whether the recording reservation data is PDC reservation (step S75). When the recording reservation data is PDC reservation, the teletext control unit 6
It is determined whether or not the date and time code in the PDC code supplied from the device matches the date and time code of the recording reservation data (step S76). If they match, the reserved recording is started (step S74), and the reserved recording is started. The operation related to the collation is ended. If the recording reservation data is not a PDC reservation in step S75, or if the date / time code in the PDC code supplied from the teletext control unit 6 does not match the date / time code of the recording reservation data in step S76, the reservation is made. The operation related to checking the start of recording ends.

Next, with reference to FIGS. 4 and 8, the operation performed by the VTR control unit 13 in the case of performing the comparison without terminating the reserved recording in step S68 in FIG. 6 will be described. VTR
When the PDC code is supplied to the control unit 13 and the VTR is executing reserved recording, first, the VTR control unit 13
It is judged whether or not the recording reservation data currently reserved for recording is a series reservation (step S81). If the series is reserved, the series code in the PDC code supplied from the teletext control unit 6 and the recording It is determined whether the series code of the reservation data matches (step S82). If the two do not match, the recording end time of the recording reservation data is set to the reservation data memory 16
Then, the time is rewritten to the time indicated by the clock of the VTR (step S83), the reserved recording is ended (step S84), and the operation relating to the collation of the reserved recording end is ended.

If it is determined in step S81 in FIG. 8 that the recording reservation data being recorded is not series-reserved, it is determined whether the recording reservation data is PDC reservation (step S85). If the recording reservation data is PDC reservation, it is judged whether the date code in the PDC code supplied from the teletext control unit 6 matches the date code of the recording reservation data (step S86), and it is determined. If not, the recording end time of the recording reservation data is rewritten in the reservation data memory 16 to the time indicated by the clock of the VTR (step S
83), the reserved recording is ended (step S84), and the operation relating to the end of reserved recording is completed. Also, step S85
If the recording reservation data is not the PDC reservation in step S86, or the P supplied from the teletext controller 6 in step S86.
