Step S31) The program length data in the program list is set to L. Step S32) The reproduction time is accumulated and set to T. Step S33) Check whether T is larger than L / 2. Step S34) If it is larger than L / 2, the "viewed" data is set in the program list. Step S35) When T is smaller than L / 2, if there is a discrepancy between the recording date and time data written on the tape and the data in the program list, the reproduction cumulative time T is reset in step S36. In this way, when a certain program is watched for half or more consecutive times, a "watched" mark can be set. Of course, this condition can be arbitrarily changed between 2/3 and 4/5.

FIG. 10 shows a method of additionally registering a program list at the time of recording. Step S50) Simultaneously with the start of recording, packet data of tape map information as shown in FIG. 4 is generated. Step S51) The current tape position is calculated based on the input data of the reel sensor 16 in FIG. 1, and is set in the tape map information. Step S52) The information from the audio multiplex decoder circuit 18 is set in the tape map information. Step S53) Count the accumulation of the recording time.

To write to the library memory. In this way, it is possible to prevent the memory from becoming full due to short-time recording.

According to the present invention, as described above, the tape map data is written in the same format as the teletext, so that the decoding position of the decoder is changed from 19H to 2H.
By simply switching to 1H, it is possible to easily display subtitle broadcasts using teletext. FIG. 11 shows the operation method. When the tape map button 141 shown in FIGS. 8 and 11 in the operation input unit 14 shown in FIG. 1 is pressed, the tape map controller 5 shown in FIG. The decoding position determination circuit 21 shown in FIG.
Set to 9H. When the subtitle button 142 in FIGS. 8 and 11 is pressed, the subtitle is set to 21H. Horizontal synchronization counter 2 in FIG.
2 counts the horizontal synchronization signal output from the synchronization separation circuit 8. When the value matches the predetermined value, the decode position determination circuit 21 causes the clock generation circuit 24 to generate a clock for sampling data. Shift register 2
3 captures the output of the data slicer 20 in accordance with the clock, and sets the data in the data register 25 when the data reaches 16 bits. The tape map controller 5 shown in FIG. 1 reads out the data, performs the above-described processing in the case of the 19H data, and performs the character signal of the ASCII data in the case of the 21H data as shown in a screen 50 in the lower diagram of FIG. Superimposed on the TV screen.

The processing procedure of the subtitle function will be described with reference to the decoding circuit 6 in FIG. 8 and 11, the caption button 14
The operation 2 is taken into the system controller 9 from the operation input unit 14 in FIG. 1 and sent to the tape map control unit 5. In response to this, the tape map control unit 5 decodes the decoding circuit 6 in order to decode the 21st H of the vertical blanking period.
Decode position determination circuit 21 of FIG.
To the value of the 21H. As a result, the decode circuit 6 compares the value of the horizontal cycle counter 22 with 21H, and controls the clock generation circuit 24 so as to generate a data sampling clock when they match.

The shift register 23 shifts the signal digitized by the data slicer circuit 20 one bit at a time in accordance with the clock, and sets the data register 25 after shifting all 16 bits. The tape map controller 5 shown in FIG. 1 reads the 16-bit data from the data register 25 shown in FIG. 2. In the subtitle mode, the 16-bit data is composed of 2-byte 7-bit data with parity. Each byte is discriminated into a character code and a control code. The control code has functions such as designation of a character display position, display color, and display font. The tape map controller 5 in FIG. 1 changes an internal control register of the screen display circuit 7 according to these control codes. By substituting the character code with display character data and setting it in the display memory of the screen display circuit 7, subtitles can be displayed as shown in the screen 50 of FIG.

In general, the display position of the subtitle is determined by the control data for specifying the display position inserted on the broadcast station side, but it is possible to disregard this and display it at a fixed position. By doing so, even when there is Japanese subtitles superimposed on the screen, it is possible to simultaneously view both without overlapping with English subtitles.

As another application of the present invention, an automatic setting function of an audio multiplex mode at the time of tape reproduction is possible. When receiving an audio multiplex broadcast, it is possible to automatically determine whether it is a bilingual broadcast or a stereo broadcast based on a pilot signal. However, conventionally, it has been impossible to determine this after being recorded on a tape. In the present invention, when recording on a tape, the data in the audio multiplex mode is written in a vertical blanking period, read out during reproduction, and controlled by an audio signal processing circuit, thereby enabling automatic selection during reproduction. I have.

FIG. 4 shows data to be recorded in the vertical flyback period 19H in the present invention. Two bits b152 and b153 of the frame 10 are portions where BIL information, that is, a voice multiplex mode is recorded. The system controller 9 shown in FIG. 1 receives the audio multiplexing mode of the main / sub signal and the stereo / monaural signal of the bilingual broadcast from the audio multiplex decoder 18 at the time of recording, and transmits the same to the tape map controller 5. The tape map controller 5 combines this data with other tape map information to create data as shown in FIG. This is sent to the encoding circuit 3 and the vertical blanking period 1
Record at 9H.

At the time of reproduction, the data is read out by the decoding circuit 6 shown in FIG. The tape map controller 5 uses the extracted BI
From the L information, an audio multiplex mode of a main / sub signal and a stereo / monaural signal of a bilingual broadcast is sent to the system controller 9. The system controller 9 receives this, and
The audio signal processing circuit 19 is set to any one of the audio output modes (left), R (right), LR, and L + R. By doing so, it is possible to reproduce in the audio mode monitored at the time of recording.

Another application of the present invention is automation of timer recording. Generally, TV programs are repeated on a weekly basis.
When recording it, it is convenient to record the same program on the same cassette. That is, when a certain cassette is placed in the VTR, this object can be achieved by recording the program on the same day / start time / channel as the program already recorded on the cassette.

FIG. 4 shows the tape map information to be written in the vertical blanking period of the video signal, which is the same as described above, but includes the remaining data at a certain recording start point, the current remaining data, the month data, and the day data. , Day of the week, start time, start minute, recording channel,
The recording mode (standard / 3 times) is basically not necessary for realizing the tape map function. One use is for recovery when library memory is corrupted. Another application is the automation of timer recording. By reading these data when the cassette tape is inserted into the VTR, data such as a recording date, a day of the week, a program start time, a recording channel, and a recording mode necessary for timer reservation can be obtained.

The recording date can be generated by extracting the current date and the current day of the week from the clock function of the VTR, and adding the difference between the recording day and the current day. Next, the VTR fast-forwards to the tail of the program at the current position.
The detection of the tail portion is performed by the blank portion erased by the erasing head. By subtracting the remaining data at the tail from the remaining data at the recording start point, the length of the recorded program can be obtained. By adding it to the program start time, the program end time can be obtained. These data, that is, recording date, day of the week, program start time, program end time, recording CH, and recording mode are set in the timer reservation memory 15 in FIG. Subsequent processing is performed in the same manner as normal timer recording.

If the remaining time of the tape in the blank portion is shorter than the length of the recorded program, the tape is rewound to the beginning. When the cassette tape is removed from the VTR, the above data is deleted from the timer reservation memory. In this way, once a certain program is recorded, the same program repeated every week can be continuously recorded in the same cassette even if a cassette is later inserted and removed.

[0032]

According to the present invention, the teletext decoder can be used for decoding the tape map information recorded during the vertical blanking period, so that the decoder configuration can be simplified and realized at a low cost. In addition, erroneous recognition at the time of tape identification is performed with the tape No. Can be solved by using the serial number for part of The operability in displaying the tape map information on the television screen and searching for a program is also improved. The efficient use of the library memory for storing the tape map information is also possible. It is also possible to display on a television screen the identification information of “seen” or “not seen” of the program recorded on the tape. The audio multiplex mode at the time of program recording can be automatically reproduced at the time of reproduction. Furthermore, a program on the same day and time channel as a program recorded on the cassette can be automatically recorded simply by inserting the cassette. Also, a subtitle display function can be added by the same circuit configuration.
