Abstract:
A reproducing apparatus having an editing function is arranged to, in response to an instruction for setting an editing program, generate a display image signal corresponding to the contents of the set editing program, to, in response to an instruction for execution of an action verification, generate a display image signal corresponding to contents of an action of a recording apparatus actually used as an external recording apparatus according to a remote operation control command transmitted to the actually used recording apparatus, and to, in response to an instruction for execution of an editing action, generate a display image signal corresponding to a status of progress of the set editing program. The arrangement enables the operator to clearly know how a verifying action is being executed for confirming whether or not the actually used recording apparatus can be remotely operated by the reproducing apparatus, how the editing work is progressing and how the reproducing apparatus is operating.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a reproducing apparatus having an editing function of performing, by using an external recording apparatus which is remotely operable, editing of signals recorded on a recording medium. 
     2. Description of Related Art 
     In performing, by using an external recording apparatus which is remotely operable, editing of signals recorded on a recording medium, the conventional reproducing apparatus has been provided with no means for confirming that the remote operation can be accurately carried out with remote operation control command codes being used for the remote operation control. Further, in adjusting the timing of transmitting the remote operation control command codes and the timing of actual start of operation of the recording apparatus to each other, the operator of the conventional reproducing apparatus has been necessitated to arrange and use an additional clock for measuring a time lag. 
     It has been another problem with the conventional reproducing apparatus that, when acceptance of remote operation commands is inhibited to prevent an erroneous operation within the reproducing apparatus, which is on the side of transmitting signals to an external recording apparatus, while the editing operation is in process, no display is provided for informing the operator of the inhibition of acceptance of remote operation commands. 
     It has been a further problem that the display area of display means of the conventional reproducing apparatus is limited. Therefore, in the conventional reproducing apparatus, it has been hardly possible to accurately display information apposite to each of operation modes of varied kinds. 
     In other words, the problems of the conventional reproducing apparatus include a shortcoming that, during the process of verifying the actions of command codes to find if a remote operation can be accurately carried out with the command codes being used, the conventional reproducing apparatus is incapable of clearly informing the operator as to when a command code is transmitted and how the external recording apparatus is acting in response to the command code. 
     Another problem in the conventional reproducing apparatus lies in that, in adjusting a time lag between the timing of transmitting a command code and the timing of the commencement of an action of the recording apparatus, the adjustment necessitates a very troublesome operation as follows. First, editing work must be tentatively performed by using a recording medium on which time information is recorded. After that, a time lag adjustment value must be computed by reproducing information from the edited recording medium. 
     A further problem lies in that no information on the inhibition of acceptance of remote operation commands within the reproducing apparatus is displayed even when acceptance of remote operation commands on the side of the reproducing apparatus is inhibited for the purpose of preventing an erroneous operation while an editing operation is in process. The absence of such a display sometimes confuses the operator, because the operator cannot instantly understand why the remote operation onto the reproducing apparatus has become invalid. 
     A still further problem with the conventional reproducing apparatus lies in that a display is made in the same mode both during a process of setting an editing program and during a process of executing an editing operation. Some of display items that cannot be displayed while an editing program is in a setting process but must be displayed while an editing operation is in process, such as a date or the like, therefore, sometimes cannot be displayed even while the editing operation is in process, because of an insufficient display space.

     DETAILED DESCRIPTION OF THE INVENTION 
     Hereinafter, a preferred embodiment of the invention will be described in detail with reference to the drawings. 
     FIG. 1 is a block diagram showing in outline the arrangement of a camera-integrated type VTR arranged according to the invention as an embodiment thereof. Referring to FIG. 1, an image pickup part  10  is composed of an optical system lens, a CCD image sensor, an automatic focusing mechanism, a zooming mechanism, etc. The image pickup part  10  operates, in accordance with instructions from a camera system control device  12 , to adjust focus, an amount of light, etc., for a field of view, to convert an optical image of the field of view obtained through the optical system lens into a video signal and to supply the video signal to a camera signal processing device  14 . The camera signal processing device  14  then processes the video signal in a predetermined manner in accordance with instructions from the camera system control device  12 , and supplies the processed video signal to a VTR block  16 . 
     A camera system operating device  18  is composed of various switches and dials (for AF on/off, AE auto/lock and programmed AE actions, etc.). A system control device  20  is arranged to supply the camera system control device  12  with information on an operation performed by the operator on the camera system operating device  18 . The camera system control device  12  is composed of a microcomputer, etc., and is arranged to control the entire camera system according to instructions coming from the system control device  20  and the camera system operating device  18 . 
     The VTR block  16  includes, among others, a mechanism part, a mechanism driving part arranged to drive the mechanism part, a mechanism part servo control device composed mainly of a microcomputer, and a video and audio signal processing part. In accordance with the instructions from the system control device  20 , the VTR block  16  records and reproduces video signals on and from a recording medium, sends the video signals to an EVF (electronic viewfinder)  22  and also sends out the video signals from an output terminal which is not shown. 
     A VTR system operating device  24  is composed of switches of varied kinds related to the VTR system and the whole apparatus (including up, down, right, left, execution, menu, reproduction (playback), fast-feeding/reverse-feeding, pause and start/stop switches). Information on any operation that is performed on the VTR system operating device  24  by the operator is supplied to the system control device  20 . A power supply mode switch  26  is provided for allowing the operator to select the power supply mode of the main body of the VTR (including on/off switching of power for the camera, VTR and editing). Information on the selected state of the switch  26  is supplied to the system control device  20 . An OSD (on-screen display) control device  28  is arranged to convert information of varied kinds of the main body into display character signals and to supply these signals to the EVF (electronic viewfinder)  22  in accordance with the instructions of the system control device  20 . The OSD control device  28  also supplies the VTR block  16  with character signals to be recorded, such as a title, a date, etc. 
     The EVF  22  is composed of either a CRT or a liquid crystal display panel or the like which is arranged to show video images to the operator. The EVF  22  displays not only the display of video images but also information of varied kinds in characters and symbols and guide information when a menu is set there. 
     The system control device  20  is composed of a microcomputer for total control over the above-stated various parts and has various functions, such as a timer function as will be described later herein. The system control device  20  is thus arranged to control the power supply mode, a shift to the operating mode of the VTR block  16 , various information displays, an editing mode, various shooting modes, storing and holding an editing program, etc. The system control device  20  is further arranged to supply an infrared remote control signal generating device  30  with signals for remotely operating an external recording apparatus. The infrared remote control signal generating device  30  is thus caused to transmit control signals to an outside space with infrared rays used as a carrier wave. An infrared remote control signal receiving device  32  is arranged, on the other hand, to receive infrared remote control signals from the outside and to supply the system control device  20  with data codes corresponding to the infrared remote control signals received. 
     FIGS. 2,  3  and  4  are flow charts jointly showing a flow of operation of the embodiment of the invention. FIGS. 5,  6  and  7  show examples of displays made while the operation of the embodiment is in process. FIG. 8 is a timing chart showing various actions of the embodiment. 
     Remote operation command codes applicable to the respective recording apparatus in use vary with the manufacturers of recording apparatuses. In the case of the embodiment, remote operation command codes of applicable manufacturers are arranged to be selected by using one item on a menu. Referring to FIGS. 5,  6  and  7  which show menu pictures, when a menu cursor  40  is located at an item reading “RECORDER SELECT”, if an execution key of the VTR system operating device  24  is pushed by the operator, a selected code action verification is executed. 
     Referring to FIG. 2, at a step S 1 , a check is made to find if an operation is performed to start the execution of the selected code action verification. If so, the flow proceeds to a step S 2 . At the step S 2 , preparation is made for transmission of the remote operation command codes of the recording apparatus of the manufacturers currently being selected. At a step S 3 , a command transmission timing timer CMD.TIMER is initialized to 0.0 second and is then caused to start counting time. The timer CMD.TIMER operates within the system control device  20  to up count at every 0.1 second after the start. At a step S 4 , the system control device  20  causes the infrared remote control signal generating device  30  to transmit a recording pause cancel command to the recording apparatus at the same time as the step S 3 . At a step S 5 , a display reading “RECORDER; REC” is made at a section  42  of the menu picture which is provided for indicating an acting state in which the recording apparatus is to be operated upon receipt of the recording pause cancel command. At a step S 6 , the flow of operation waits until the count value of the command transmission timing timer CMD.TIMER reaches 5.0 seconds. 
     When the count value of the command transmission timing timer CMD.TIMER reaches 5.0 seconds, the flow proceeds to a step S 7 . At the step S 7 , a timing adjusting clock display timer ADJUST.TIMER is initialized to a value of +5.0. At a step S 8 , a cut-out timing adjusting clock is started to be displayed. The cut-out timing adjusting clock may be displayed in the same size as other character displays, and, however, is preferably displayed in a larger size than other character displays as shown at a section  44  in FIG.  5 . 
     At a step S 9 , the flow waits until the count value of the command transmission timing timer CMD.TIMER is updated by 0.1 second. The flow then proceeds to a step S 10 . At the step S 10 , the count value of the timing adjusting clock display timer ADJUST.TIMER is decremented by 0.1. The display of the cut-out timing adjusting clock (for example, the section  44  in FIG. 5) is also updated. At a step S 11 , the steps S 9  and S 10  are repeated until the count value of the command transmission timing timer CMD.TIMER reaches 10.0 seconds. 
     When the count value of the command transmission timing timer CMD.TIMER is found to have reached 10.0 seconds at the step S 11 , the flow proceeds to a step S 12  which is shown in FIG.  3 . 
     At the step S 12 , a recording pause command is transmitted to the recording apparatus. At a step S 13 , the acting state in which the recording apparatus is to be operated upon receipt of the recording pause command is displayed as “RECORDER; REC PAUSE”, as shown in a section  43  in FIG.  6 . At a step S 14 , the flow waits until the count value of the command transmission timing timer CMD.TIMER is updated by 0.1 second. After updating of the timer, the flow proceeds to a step S 15 . At the step S 15 , the count value of the timing adjusting clock display timer ADJUST.TIMER is decremented by 0.1. The display of the cut-out timing adjusting clock (for example, the section  44  in FIG. 5) is also updated accordingly. At a step S 16 , the flow repeats the steps S 14  and S 15  until the count value of the command transmission timing timer CMD.TIMER reaches 11.0 seconds. 
     When the command transmission timing timer CMD.TIMER reaches 11.0 seconds, the flow proceeds to a step S 17  to bring the display of the cut-out timing adjusting clock to an end. A display resulting from this step is shown in FIG.  6 . 
     At a step S 18 , the flow waits until the count value of the command transmission timing timer CMD.TIMER reaches 20.0 seconds. When the command transmission timing timer CMD.TIMER reaches 20.0 seconds, the flow proceeds to a step S 19 . At the step S 19 , the recording pause cancel command is transmitted to the recording apparatus. At a step S 20 , the acting state in which the recording apparatus is to be operated upon receipt of the recording pause cancel command is displayed as “RECORDER; PAUSE”, as shown in the section  44  in FIG.  7 . Then, the flow proceeds to a step S 21  which is shown in FIG.  4 . 
     At the step S 21 , the timing adjusting clock display timer ADJUST.TIMER is initialized to 0.0 second. At a step S 22 , a cut-in timing adjusting clock is started to be displayed. As in the case of the cut-out timing adjusting clock, although the cut-in timing adjusting clock may be displayed in the same size as other display characters, it is preferably displayed in a larger size than other display characters, as shown in a section  46  in FIG.  7 . 
     At a step S 23 , the flow waits until the count value of the command transmission timing timer CMD.TIMER is updated by 0.1 second. When the count value of the command transmission timing timer CMD.TIMER is updated, the flow proceeds to a step S 24 . At the step S 24 , the count value of the timing adjusting clock display timer ADJUST.TIMER is decremented by 0.1. The display of the cut-in timing adjusting clock, which is, for example, as shown in the section  46  in FIG. 7, is also updated accordingly. At a step S 25 , the steps S 23  and S 24  are repeated until the count value of the command transmission timing timer CMD.TIMER reaches 25.0 seconds. 
     When the count value of the command transmission timing timer CMD.TIMER has reached 25.0 seconds at the step S 25 , the flow proceeds to a step S 26  to put out the display of the cut-in timing adjusting clock. At a step S 27 , the flow waits until the count value of the command transmission timing timer CMD.TIMER reaches 30.0 seconds. 
     When the count value of the command transmission timing timer CMD.TIMER reaches 30.0 seconds, the flow proceeds to a step S 28  to transmit the recording pause command to the recording apparatus. At a step S 29 , the display of the acting state in which the recording apparatus is to be operated is put out, and the selected code action verification comes to an end. 
     Further, the signals for the displays of various kinds are line-outputted. Therefore, a recording medium for timing adjustment can be perfectly completed by connecting the display signals to the line inputs of the recording apparatus and actually performing a recording action under the work of the above-stated selected code action verification. Incidentally, when a signal recorded on the recording medium for timing adjustment is reproduced, clock display data which is obtained at a change-over point from the display of the cut-out timing adjusting clock to the display of the cut-in timing adjusting clock becomes a timing adjustment value applicable to each adjustment of timing. Therefore, the data thus obtained is set as timing adjustment data for each timing. 
     FIG. 9 is a flow chart showing an operation in the editing mode in the embodiment. FIGS. 10 and 11 show by way of example displays made during the operation. 
     Referring to FIG. 9, at a step S 31 , a check is made to find if an editing execution mode is turned on by the execution key of the VTR system operating device  24 . If not, the flow of operation proceeds to a step S 39 . At the step S 39 , the VTR is permitted to accept remote operation commands, and a display “S_OFF” indicating inhibition of acceptance of remote operation commands, shown at a part  50  in FIG. 11, is put out. Then, the flow proceeds to a step S 40  to shift the mode of display to a normal editing mode display as shown in FIG. 10, and returns to the step S 31 . In the display shown in FIG. 10, display parts  52 - 1  to  52 - 8  indicate the contents of a preset editing program. As shown, editing program parts No.  1  to No.  8  have already been registered. In the case of FIG. 10, the whole space of the picture has already been fully used for display of information. There is left no room for any more information display. 
     If the editing execution mode is found at the step S 31  to have been turned on by the execution key of the VTR system operating device  24 , the flow proceeds to a step S 32 . At the step S 32 , the system control device  20  inhibits acceptance of remote operation commands at the VTR for the purpose of preventing the editing work from being suspended by any erroneous operation from the outside. At the same time, the system control device  20  causes the command acceptance inhibition display “S_OFF” to be turned on, as shown at the display part  50  in FIG.  11 . 
     At the next step S 33 , an editing execution mode display is turned on as shown in FIG.  11 . At a step S 34 , only the display of a part of the editing program currently in process of execution is inverted as shown by way of example at a part  54  in FIG.  11 . In the case of this display example, the editing program is indicated at a part  56  and a part of the editing program which is currently in process of execution is shown in an inverted state at the part  54  in FIG.  11 . The inverted display part clearly shows that the first part of the editing program is now in process of execution. 
     At a step S 35 , a check is made to find if a date code has been turned on. If so, the flow proceeds to a step S 36  to turn on a display of date code as shown at a part  58  in FIG.  11 . If not, the flow proceeds to a step S 37  to put out the display of date code. At the next step S 38 , a check is made to find if the editing action of the whole editing program has been finished. If not, the flow returns to the step S 33  to repeat the step S 33  and steps subsequent thereto. If so, the flow returns to the step S 31 . 
     As will be readily understood from the foregoing description, the start and end of the verifying work on the action of the command codes selected to be actually used become clear, so that the reliability of the verifying action can be enhanced by the arrangement of the embodiment described above. 
     Further, the arrangement for making a display of clock adjusted to the timing of transmission of the command codes while the selected code action verification is in process enables the editing work to be accurately carried out, because a recording medium which facilitates timing adjustment for accurate editing work can be prepared at the same time as the process of the selected code action verification by virtue of the arrangement described above. 
     The arrangement for making a clock display in a size larger than a normal character display size permits easy clock confirmation during the process of setting a timing adjusting value. 
     The arrangement for providing a means for inhibiting acceptance of commands while the editing work is in process (in the editing execution mode) effectively enables the operator to clearly know whether acceptance of commands is being inhibited or not. 
     The arrangement for making a display provided during the process of setting the editing program (editing program setting mode) different from a display provided during the process of executing the editing work (editing execution mode) enables some item that cannot be displayed in the editing program setting mode because of the limited space but must be displayed in the editing execution mode, such as a date display, to be displayed as necessary.
