[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a magnetic recording / reproducing apparatus such as a video tape recorder (VTR) having a function of skipping and reproducing a CM broadcast. In particular, a CTL signal is recorded during a CM broadcast time zone during recording, and is reproduced at the time of reproduction. The present invention relates to a magnetic recording / reproducing apparatus that can broadcast a CM portion or automatically cut a CM portion.

[0002]

[Prior art]

 There have been proposed various magnetic recording / reproducing apparatuses which allow a CM broadcast to be skip-reproduced during reproduction after a television broadcast program is recorded on a video tape by a VTR. As one example, there is known a video tape reproducing apparatus capable of causing an unnecessary portion to be fast-forwarded during reproduction (see Japanese Patent Application Laid-Open No. H10-112090). The video tape reproducing apparatus includes a reproducing unit, a fast-forwarding unit, a signal recording unit, a signal detecting unit, a control unit, and the like as main parts. Then, when the reproducing means reproduces the tape, the signal recording means records the first signal at the first position of the tape, and records the second signal at the second position following the first position. Thereafter, when the control means causes the reproducing means to reproduce the tape signal, the signal detecting means activates the fast-forward means when the first signal is detected, and stops the operation of the fast-forward means when the second signal is detected. It has become. As a result, after the entire program including unnecessary parts such as commercials is recorded as it is, when the tape is played back, the unnecessary parts are automatically fast-forwarded. It is going to disappear.

Also, a digital data recording / reproducing method and apparatus for realizing a CM skip function realized by analog broadcasting as described above, which can be realized by digital broadcasting, is known (see Japanese Patent Application Laid-Open No. 11-185317). ). This device includes a receiving unit, a recording unit, a reproducing unit, a detecting unit, a control unit, and the like as main parts. The recording unit operates such that the control unit skips the commercial material indicated by the position information. And playback means. Then, based on the insertion information (queue information) of the CM portion inserted in the digital broadcast program, the CM portion is prevented from being recorded on the recording medium, or the CM portion of the digital broadcast program once recorded on the recording medium as it is is deleted. Skip playback is enabled. Therefore, the CM skip function realized by analog broadcasting can be realized by digital broadcasting.

[0004]

[Problems to be solved by the invention]

 By the way, the conventional video tape reproducing apparatus detects a difference between a monaural main program broadcast and a stereo CM broadcast at the time of recording, and cuts the CM broadcast portion in order to determine whether or not there is a CM broadcast in a TV broadcast program. I try to make it. However, when the received radio wave is weak, it is difficult to detect monaural and stereo, so that monaural may be determined to be stereo, and the main broadcast may be mistaken for a CM broadcast to cut the recording of the main broadcast. As a result, there has been a problem that a part of the main broadcast is not displayed during reproduction, and the entire broadcast program cannot be viewed. The latter digital data recording / reproducing method and its apparatus have a CM skip function. However, a CM time zone that is several minutes before and after a regular time, such as 8:00 pm and 9:00 pm, is predicted to cut a CM. Since it is not a discrimination method, as described above, it was not possible to cope with a change in the status of the received radio waves or a deviation in the broadcast time, and the problem that the main broadcast could not be recorded with high accuracy remained.

The present invention has been made in view of the above problem, and predicts a time zone of a CM broadcast at the time of recording and records an accurate discrimination signal. Another object of the present invention is to provide a magnetic recording / reproducing apparatus which can be viewed without being damaged.

The signal is sent to the Y / C / A separation circuit 2.

The Y / C / A separation circuit 2 separates an input signal and converts a video signal to a video signal processing unit (not shown) composed of a chroma IC and an audio signal to an audio signal processing unit 3 composed of a stereo IC. Each is output. The video signal processing unit extracts video information from the video signal and sends it to the image processing circuit 5 side. The output of the image processing circuit 5 is connected to the CRT 7, and outputs image information to the CRT 7 under the control of the control unit 18. The audio signal processing unit 3 is connected to the control unit 18 and to the speaker 4 via a speaker driving circuit (not shown). The audio signal processing unit 3 has an audio switching determining function of determining switching between stereo and monaural. Among the audio signals transmitted to the speaker driving circuit, a monaural or CM broadcast, which is a main part of a broadcast program, is provided. Each of the stereo detection signals indicating the portion is output to the control section 18 at each switching. The signal when stereo is detected is referred to as a first switching signal C1, and the signal when monaural is detected is referred to as a second switching signal C2.

Reference numeral 6 denotes an OSD circuit (ON SCREEN DISPLAY), which is connected to a synthesizing unit (not shown) on the output side of the image processing circuit 5, and is supplied to the memory 17 in advance based on a command from the control unit 18. The stored display data and the like are signalized and output to the synthesizing unit. Reference numeral 8 denotes a recording / playback processing unit, whose output is connected to the recording / reproducing head 9. The recording / playback processing unit 8 is bidirectionally connected to the control unit 18 and is also connected to the mechanical control circuit 13. The recording / reproducing processing unit 8 sends a video / audio signal to the recording / reproducing head 9 under the control of the control unit 18 to record the video / audio signal on the recording area V2 of the video tape V shown in FIG. Further, the recording / reproducing head 9 sends the reproduced video / audio signal read from the recording area V2 to the control section 18. An encoder 10 is connected to the control unit 18 and a CTL signal recording / reproducing head (CTL recording / reproducing head) 12.

The encoder 10 writes a CTL signal recording area (CTL area) V1 of the video tape V when a first time signal t1 indicating a position several minutes before the regular time is transmitted from the control unit 18. The signal is converted into a possible signal form and transmitted to the CTL recording / reproducing head 12. Also, when a second time signal t2 indicating several minutes after the regular time is transmitted from the control unit 18, the signal is converted into a writable signal form and transmitted. When a first switching signal C1 indicating a cutting start position of an unnecessary part such as a CM is transmitted from the control unit 18 in response to the stereo detection signal, a signal that can be written in the CTL area V1 of the video tape V It is converted into a form and sent to the CTL recording / reproducing head 12. Further, when the control unit 18 sends out the second switching signal C2 indicating the cut end position of an unnecessary part such as a CM according to the monaural detection signal, the signal is converted into a writable signal form and sent out. .

A decoder 11 is connected to the controller 18 and the CTL recording / reproducing head 12. The decoder 11 decodes the reproduction signal read from the CTL area V1 of the video tape V by the CTL recording / reproducing head 12, and outputs the first and second time signals t1, t2 and the first and second switching signals C1. , C2 to the control unit 18 side. Reference numeral 13 denotes a mechanical control circuit, which is connected to a servo circuit, a tape running mechanism, and the like (not shown), and is also connected to a control unit 18. The mechanical control circuit 13 controls the operation of a recording system and a reproduction system including a servo circuit and a tape running mechanism based on a control signal from the control unit 18 and performs a recording and a reproduction process. .

A receiving unit 15 receives an infrared signal from the remote control transmitter 14 and sends a transmission signal to the control unit 18. The remote controller 14 has power keys and menu keys arranged on an operation surface, and a PLAY, FF, REW, STOP, REC key and the like in addition to a numeric keypad on a key input section. In this example, menu items are displayed on the screen of the CRT 7 by operating the menu keys, normal reservation setting is performed using each key of the key input section, and automatic recording setting and automatic reproduction setting of the CM cut are performed. To do. The CM cut automatic recording setting includes a CM predicted time setting in which the first time signal t1 and the second time signal t2 are automatically recorded several minutes before and several minutes after the regular time, and a CM broadcast in the CM predicted time zone. This is a CM time setting for automatically recording the first and second switching signals C1 and C2 every time the start or the end is completed. On the other hand, in the automatic reproduction setting of the CM cut, the reproduction is stopped when the first switching signal C1 is detected during the reproduction of the video tape V, the video tape V is fast-forwarded, the CM is cut, and then the return to the constant speed reproduction is performed. Reproduction.

Reference numeral 18 denotes a control unit composed of a microcomputer, which includes a timer 16 and a memory 17 and is connected in one direction or bidirectionally in accordance with the circuit units and their functions. The memory 17 stores various control programs for recording or reproducing video and audio signals. The control unit 18 controls the operation of the VTR based on a command signal from the remote controller 14, and controls the operation of recording the video / audio signal on the video tape V or reproducing the recorded signal. Also, the control program stored in the memory 17 is read out and executed based on the setting contents of the menu. In this control program, the CM prediction time setting is performed by the input operation of the remote controller 14 as described above. However, as shown in FIG. 2, in this example, the CM prediction time zone T1 is set several minutes before the positive time. After 5 minutes, several minutes later, the whole time is 10 minutes in 5 minutes.

Next, the reservation recording operation of the VTR will be described with reference to the flowchart of FIG. When the user wants to record a two-hour TV broadcast program starting at 8:00 pm on a certain day, a reservation operation for the channel, start time, end time, and the like is performed in advance by input operation of the remote controller 14. Along with this, a broadcast program reservation program is set together with the previously set CM estimated time as described above. First, the control unit 18 receives the time data from the timer 16, shifts to the CM cut recording mode when the recording start time comes, and starts recording by operating the recording system. As a result, video and audio signals are recorded on the recording area V2 of the video tape V shown in FIG. In a TV broadcast program, since the main part of the audio signal is usually monaural, a monaural audio signal is recorded after recording is started.

Next, the control unit 18 determines whether or not it is 5 minutes before the first regular time (step S11), and at 20:55 which is 9: 5 pm before the first time. After generating the signal t1, it is sent to the encoder 10. When the first time signal t1 is transmitted, the encoder 10 converts the first time signal t1 into a signal form that can be written in the CTL area V1 of the video tape V and transmits the signal to the CTL recording / reproducing head 12. Therefore, the first time signal t1 is recorded in the CTL area V1 at around 20:55. Thereafter, the control unit 18 determines whether or not the first switching signal C1 indicating stereo detection has been transmitted from the audio signal processing unit 3 (step S13). When this broadcast program starts commercial broadcasting at 20:58, the first switching signal C1 is sent from the audio signal processing unit 3 to the control unit 18. The control unit 18 sends a first switching signal C1 to the encoder 10 according to the input of the stereo detection signal. Therefore, the first switching signal C1 is recorded in the CTL area V1 at around 20:58 (step S14).

Subsequently, the control unit 18 determines whether or not the audio signal processing unit 3 has transmitted the second switching signal C2 indicating monaural detection (step S15). When this broadcast program ends the CM broadcast at 21:03 and returns to the main broadcast again, a monaural detection signal is sent from the audio signal processing unit 3 to the control unit 18. The control unit 18 sends the second switching signal C2 to the encoder 10 according to the input of the monaural detection signal. Therefore, the second switching signal C2 is recorded in the CTL area V1 at the time of 21:03 which has passed 5 minutes which is the CM broadcasting time zone T2 (step S16). Next, the control unit 18 determines whether or not it is 5 minutes after the regular time (step S17), and generates a second time signal t2 at 21:05 which is 9:05 pm. Then, it is transmitted to the encoder 10. Therefore, the second time signal t2 is recorded in the CTL area V1 at around 21:05 (step S18). Thereafter, the control unit 18 determines whether or not the recording end time based on the reservation program has been reached (step S19). If not, the process proceeds to step S11 to determine whether or not the current time is five minutes before the regular time. And continues recording the time signal and the CM start and end signals. On the other hand, when the recording end time comes, the operation of the recording system is stopped and a series of recording operations is ended.

Next, the reproduction operation of the VTR will be described with reference to the flowchart of FIG. When the user wants to play back with the CM cut, the automatic playback setting is made in advance by operating the menu key. When the PLAY key of the remote controller 14 is operated after the video cassette on which the TV broadcast program is recorded is mounted on the VTR, the control unit 18 starts the operation of the reproduction system. Then, the video tape V runs at a constant speed (step S 21), and the recording signal of the recording area is read by the recording / reproducing head 9 and transmitted to the recording / reproducing processing unit 8. Along with this, the reproduced audio signal is transmitted to the speaker 4 side, so that the sound of the main part of the broadcast program is emitted. When the reproduced video signal is transmitted to the CRT 7, the main video is displayed on this screen.

When the reproduction is started in this way, the control unit 18 determines whether the first switching signal C1 has been transmitted from the decoder 11 (step S22). When the CTL recording / reproducing head 12 reads the first switching start signal C1 due to the running of the video tape V, the decoder 11 decodes this and sends it to the control unit 18. Upon receiving the first switching start signal C1, the control unit 18 suspends the reproducing operation of the reproducing system and causes the video tape V to fast-forward (steps S23 and S24). As a result, the recorded portion of the CM broadcast is skipped at high speed without being reproduced. Next, the control unit 18 determines whether or not the second switching start signal C2 has been transmitted from the decoder 11 (step S25). Here, when the CTL recording / reproducing head 12 reads the second switching start signal C2 and receives the second switching start signal C2 from the decoder 11, the control unit 18 restarts the reproducing operation of the reproducing system at a constant speed. (Step S26).

Thereafter, the control unit 18 checks the transmission signal from the recording / reproduction processing unit 8 and determines whether or not the reproduction has been completed (step S27). If the signal reproduction of the video tape V is continued, the process returns to step S21 and proceeds to step S22 to determine whether or not the first switching start signal C1 has been transmitted. When the first switching start signal C1 is input, the reproduction is temporarily stopped, the tape is fast-forwarded, and the CM is skipped. When the CM ends, the reproduction is shifted to the constant speed reproduction again. On the other hand, when the signal reproduction of the video tape V is completed, the operation of the reproduction system is stopped, and a series of reproduction operations is terminated.

In the above-described embodiment, recording / playback based on the reservation program has been described. However, the above-described automatic recording of the CM cut can be performed even in the normal recording performed by manually operating the REC key of the remote controller 14. is there. Further, when the video / audio signal is recorded, after the first time signal t1 and the first switching signal C1 are recorded, when the second switching signal C2 is not input within the input time of the second time signal t2. May be provided with a control program for recording the second switching signal C2 at the time of input without recording the second time signal t2. Thus, even if the CM broadcast continues for a long time after the second time signal t2, it is not recorded on the video tape V, so that a broadcast program or the like in which only unnecessary CM portions are appropriately cut is viewed. be able to.

When recording the video / audio signal, if the first switching signal C1 is input after recording the first time signal t1, the recording of the video / audio signal is stopped, and the second switching is performed. A control program for restarting recording of the video / audio signal at the time of input of the signal C2 may be provided. This makes it possible to record a broadcast program or the like while appropriately cutting only unnecessary CM portions. Further, when reproducing the video / audio signal, if a CM cut reproduction command is not received, a control program that does not stop reproduction even when a time signal and a switching signal are input may be provided. In this way, it is possible to select whether or not to listen to the CM broadcast by a user's arbitrary operation.

[0024]

[Effect of the invention]

 As described above, the invention according to claim 1 of the present invention is characterized in that the first and second time signals are recorded a few minutes before and a few minutes after the correct time when recording the video and audio signals based on the reservation program. After recording the first and second switching signals according to the switching between monaural and stereo, respectively, when reproducing the video / audio signal, the first time signal is input and the first time signal is input. When the switching signal is input, the reproduction of the video / audio signal is stopped, and then, when the second time signal is input and the second switching signal is input, the reproduction is restarted. When playing back the video and audio signals after recording them on the recording area of the video tape, listen to a broadcast program or the like in which only unnecessary CM parts have been properly cut off without deleting part of the main part. There is an effect that can be seen.

Further, the invention according to claim 2 records the first and second time signals several minutes before and after the correct time at the time of recording the video / audio signal based on the reservation program, Also, after recording the first and second switching signals in accordance with the switching between monaural and stereo, respectively, when reproducing the video / audio signal and receiving a CM cut reproduction command, the first time signal is input. When the first switching signal is input, the reproduction of the video / audio signal is stopped, and subsequently, when the second time signal is input and the second switching signal is input, the reproduction is restarted. When the radio wave was received and its video and audio signals were recorded on the recording area of the magnetic tape and played back, only the unnecessary CM parts were properly cut without deleting the main part. There is an effect that a broadcast program or the like can be viewed.

According to a third aspect of the present invention, after the control means records the first time signal and the first switching signal, the second switching signal is not input within the input time of the second time signal. Since the second time signal is recorded at the input time point without recording the second time signal, it is not recorded even if the CM broadcast is continued for a long time, and only unnecessary CM portions are appropriately cut. There is an advantage that a broadcast program or the like can be viewed. Further, in the invention according to claim 4, when the control means records the first time signal and the first switching signal is input, the recording of the video / audio signal is stopped, and the control of the second switching signal is stopped. Since recording of video / audio signals is resumed at the time of input, there is an advantage that recording of broadcast programs and the like can be performed while appropriately cutting only unnecessary CM portions. Further, according to the invention of claim 5, when the control means does not receive a reproduction command of the CM cut when reproducing the video / audio signal, the reproduction is not stopped even if the time signal and the switching signal are inputted. There is an advantage that whether or not to listen to the CM broadcast can be selected by a user's arbitrary operation.
