CROSS REFERENCE TO RELATED APPLICATIONS This application is a divisional application of application Ser. No. 09/211,478, filed Dec. 14, 1998 now U.S. Pat. No. 6,526,218.
Heretofore, a dubbing editing system has been known for dubbing a video signal recorded on a recording medium such as a video tape into another apparatus such as a video tape redorder while editing the video signal.
Further, in recent years, a system having such a structure as to control the operation of a receiving-side video tape recorder in the following manner has been developed. A sending-side video tape recorder contains therein a transmitting part of an infrared remote-control device. Among a plurality of kinds of control command codes stored in the infrared remote-control device, control command codes for controlling the operation corresponding to the manufacturer or type of the receiving-side video tape recorder are selected. According to the control command codes as selected, a control command is sent from the transmitting part of the infrared remote-control device to the receiving-side video tape recorder during the above-mentioned dubbing editing operation so as to control the operation of the receiving-side video tape recorder.
BRIEF SUMMARY OF THE INVENTION It is a general object of the invention to provide an editing-function-integrated reproducing apparatus capable of solving the above-mentioned problems.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING FIG. 1 is a block diagram showing in outline the arrangement of a camera-integrated type video tape recorder (VTR) according to a first embodiment of the invention.
FIGS. 4( a) to 4(d) show examples of displays made on the picture plane of an EVF (electronic viewfinder) part of the camera-integrated type VTR shown in FIG. 1 during registration of editing points and during execution of an editing operation.
FIGS. 7( a) to 7(d) show examples of displays made on the picture plane of an EVF (electronic viewfinder) of the camera-integrated type VTR shown in FIG. 5 during registration of editing points and during execution of an editing operation.
FIGS. 4( a) to 4(d) show examples of displays made on the picture plane of the EVF part 3 of the camera-integrated type VTR shown in FIG. 1 during registration of editing points and during execution of an editing operation.
In the case of the camera-integrated type VTR according to the first embodiment of the invention, the video signal and the audio signal are recorded respectively in the form of digital data. Each of a plurality of recording tracks formed when the surface of the magnetic tape is traced by the rotary magnetic head is provided with a video sector in which the video data is recorded and an audio sector in which the audio data is recorded. Further, the video sector is provided with a VAUX area for recording auxiliary information data VAUX, which is to be recorded together with the video data. The audio sector is likewise provided with an AAUX area for recording auxiliary information data AAUX, which is to be recorded together with the audio data.
In the case of the first embodiment, reproduction-restricting information data on restriction of reproduction of video or audio data is made to be set in the VAUX area or the AAUX area. More specifically, the reproduction-restricting information data (SS flag) indicative of the restriction of reproduction of the video data is set in the VAUX area of the video sector. The reproduction-restricting information data (SS flag) indicative of the restriction of reproduction of the audio data is set in the AAUX area of the audio sector.
If the reproduction-restricting information included in the reproduced data is found at the step S02 to be invalid, the flow of operation proceeds to a step S03. At the step S03, a check is made to find if a cut-in point has already been registered. If not, the flow proceeds to a step S04 to register the cut-in point. At a step S05, a time code for the registered cut-in point is displayed on the picture plane of the EVF part 3 shown in FIG. 1, as shown in FIG. 4( a). At a step S06, a check is made to find if there is a program to be next registered. If not, the flow brings the editing-point registering operation to an end. If so, the flow returns to the step S02. In a case where the cut-in point is found at the step S03 to have already been registered, the flow proceeds to a step S07. At the step S07, a cut-out point is registered, and the flow proceeds to a step S08. At the step S08, a program number is updated for a program to be next registered. If no program to be next registered is found at the step S06, the editing-point registering operation comes to an end. If there is a program to be next registered, the flow returns to the step S02.
If the reproduction-restricting information as detected is found at the step S02 to be valid, the flow of operation proceeds from the step S02 to a step S09. At the step S09, in order to indicate that an area on the magnetic tape which is about to be registered as an editing point is in a state of being inhibited from being registered as the editing point (i.e., an area where a video signal or an audio signal which is restrained from reproduction is recorded is about to be registered as the editing point), a character display related to registration of the applicable program is made to flicker on the picture plane of the EVF part 3 shown in FIG. 1, as shown in FIG. 4( b). After the step S09, if there is no program to be registered next, the flow returns through the step S06 to the step S02.
When the operation part 6 shown in FIG. 1 is operated by the user, an instruction for starting execution of the editing operation is given to the system control part 4. Then, at a step S10 of FIG. 3, the reproduction-restricting level �n� is set. The reproduction-restricting level for execution of the editing operation is displayed in characters on the picture plane of the EVF part 3 shown in FIG. 1, as shown in FIG. 4( c) or 4(d). At a step S11, the system control part 4 sets the operating mode of the VTR block 5 to a reproduction mode in which a reproducing action is performed on the magnetic tape. Then, the magnetic tape is subjected to a high-speed search reproduction until the first cut-in point registered in the editing program is found. At the same time, an infrared remote-control signal is transmitted, as a control command, from the infrared remote-control-signal generating device 7 to the other VTR which is employed as a receiving-side recording apparatus, to set the receiving-side VTR into a pause state. After that, various control flags are initialized.
At the step S15 of FIG. 3, the check is made to find if the reproduction-restricting level indicated by the reproduction-restricting information data included in the data reproduced from the magnetic tape is equal to or less than the reproduction-restricting level �n� set at the step S10. If not, the check at the step S15 is repeated until either the reproduction-restricting level indicated by the reproduction-restricting information data included in the data reproduced from the magnetic tape becomes equal to or less than the reproduction-restricting level �n� set at the step S10 or the reproduction-restricting information data becomes invalid. The flow then proceeds from the step S15 to a step S16. At the step S16, an infrared remote-control signal indicative of a control command for cancelling the pause state of the other VTR serving as a receiving-side recording apparatus is sent from the infrared remote-control-signal generating device 7 to the other VTR. At the same time, the output flag is set to �1�, and then the flow proceeds from the step S16 to a step S17.
By virtue of the procedures set forth as shown in the flow chart described above, in carrying out the dubbing editing operation according to a registered editing program, the operating state of the receiving-side recording apparatus is changed automatically to a non-recording state if the reproduction-restricting information which is valid is detected in the signal reproduced from a recording medium. If no valid reproduction-restricting information is detected in the signal reproduced, the receiving-side recording apparatus is automatically set in a recording state. Therefore, even if the reproduction-restricting information added to video data or audio data recorded on the recording medium is found to be valid, the dubbing editing operation can be carried out in such a way as to adequately exclude any period of having no image or no sound from the result of the dubbing editing operation. Further, in a case where a plurality of reproduction-restricting levels are set for reproduction of video or audio signals, the receiving-side recording apparatus is automatically set into a non-recording state, if a reproduction-restricting level indicated by reproduction-restricting information added to the signal reproduced from the recording medium is found to be higher than the reproduction-restricting level set at the commencement of execution of editing, and the receiving-side recording apparatus is automatically set into a recording state if the reproduction-restricting level indicated by reproduction-restricting information added to the signal reproduced from the recording medium level is found to be equal to or less than the reproduction-restricting level set at the commencement of execution of editing. The arrangement for setting a reproduction-restricting level at the commencement of editing enables the user to selectively obtain one of different results of editing as desired.
FIGS. 7( a) to 7(d) show examples of displays made on the display picture plane of the EVF part 13 of the camera-integrated type VTR shown in FIG. 5 during registration of editing points.
At the step S23 of FIG. 6, a check is made to find if a cut-in editing point has already been registered. If not, the flow proceeds to a step S24 to register the cut-in editing point. At a step S25, a time code for the registered cut-in editing point is displayed on the picture plane of the EVF part 13 shown in FIG. 5, as shown in FIG. 7( a). The flow proceeds from the step S25 to a step S26 to make a check to find if there is a program to be next registered. If so, the flow returns to the step S21. If the cut-in editing point is found at the step S23 to have already been registered, the flow proceeds to a step S27. At the step S27, a cut-out editing point is registered, and the flow proceeds to a step S28. At the step S28, a program number is updated for a program to be next registered. If no program to be next registered is found at the step S26, the editing-point registering operation comes to an end.
As apparent from the description given above, the cut-in and cut-out editing points of each editing program are registered by the user of the VTR while the user is watching, for confirmation, the video and audio records reproduced from the magnetic tape. However, if any of the time codes to be used for registering the editing points is an interpolated time point, as mentioned above, a point on the magnetic tape represented by the time code used for registration is not adequately in correspondence to an actual point of the magnetic tape where the signals corresponding to the images and sounds confirmed by the user are recorded. In the event of such a time code, therefore, it is hardly possible to carry out the editing operation to obtain any desired result of editing.
To solve this problem, the camera-integrated type VTR described above according to the second embodiment of the invention is arranged to inhibit registration of any editing point in cases where the magnetic tape transport speed is higher than the speed for normal reproduction by two times or more than two times and where a time code to be registered as an editing point is an interpolated time code. In addition to that, in such a case, the VTR is arranged to inform the user of the inhibited state with a warning display. The warning is given either by showing the inhibited state on the picture plane of the EVF part 13 shown in FIG. 5 or by causing an external video output to output a video signal with characters indicating the registration inhibited state superimposed on the video signal, as shown in FIGS. 7( b) to 7(d). That arrangement enables the user to easily know that the time code in question is in the state of being inhibited from registration. Therefore, in the event of any defective time code that is inadequately in correspondence to a position where a signal corresponding to an image or sound to be edited is actually recorded on the magnetic tape, such a defective time code can be effectively prevented from being inadvertently registered as an editing point. The arrangement disclosed thus enhances the operability of the reproducing apparatus.
