Hereinafter, embodiments of the present invention will be described in detail, with reference to the accompanying drawings as necessary.
Here, referring to a front view, a side view, and a plan view of the external recording apparatus 3 as shown in
While the menu screen is displayed on the display section 5, the fast-forward operation unit 10 and the rewind operation unit 12 function as operation units for moving a cursor displayed on the menu screen, and the play operation unit 11 functions as an enter operation unit for issuing an instruction to select a menu indicated by the cursor. While the menu screen is not displayed, the stop operation unit 7 functions as a play stop operation unit for issuing an instruction to stop playback. If the power operation unit 15 is operated at the central position, power is turned off, whereas if a slide operation is carried out upward or downward from the central position, the power is turned on to start a video mode or a computer mode, respectively. Note here that the video mode and the computer mode refer to an operation mode in which the external recording apparatus operates as an external recording apparatus for the video equipment and an operation mode in which the external recording apparatus operates as an external recording apparatus for the computer, respectively.
Under control of a sub-CPU 24 and the main apparatus, the main CPU 21 transmits or receives various commands or statuses to or from the main apparatus via the interface 23. In addition, the main CPU 21 receives video data, audio data, and so on from the main apparatus via the interface 23, and records the received data on the hard disk drive 22. In addition, conversely, the main CPU 21 reproduces the data from the hard disk drive 22, and outputs the reproduced data to the main apparatus via the interface 23. The main CPU 21 uses a memory 25 as a buffer memory to record or reproduce the data, and when in the video mode, the main CPU 21 performs a process of cache recording. Note here that the “cache recording” refers to a recording mode in which the video data and the audio data are sequentially recorded on the memory 25 cyclically while waiting for start of the recording, and if an instruction to start the recording is issued, the recording is stared with the video data and the audio data recorded on the memory 25 so that extra data corresponding to a period of several seconds prior to the issuance of the instruction to start the recording will be recorded.
In addition, the main CPU 21 transmits or receives, to or from the sub-CPU 24, various types of data necessary for processing by the sub-CPU 24. Moreover, upon notification from the sub-CPU 24 of detection of a falling, the main CPU 21 instructs the hard disk drive 22 to retract a head thereof. Still further, the main CPU 21 displays various types of information provided from the sub-CPU 24 on the display section 5. Note here that examples of the information displayed include the menu screen and the status (e.g., statuses, such as “during recording” or “during playback,” a time code, remaining battery life of the battery 4, etc.) of the external recording apparatus 3.
A falling sensor 26 is an acceleration sensor, and detects a falling of the external recording apparatus 3 and notifies the sub-CPU 24 of the falling. A memory 27 is formed by an EEPROM, for example, and records and holds a program for the sub-CPU 24 and various types of data necessary for execution of this program. Thus, in this external recording apparatus 3, the program executed by the sub-CPU 24 is provided by being installed in the external recording apparatus 3 beforehand. Alternatively, the program may be provided by being recorded on a recording medium such as an optical disc, a magnetic disk, or a memory card, or may be provided by being downloaded via a network such as the Internet.
The sub-CPU 24 executes the program recorded on the memory 27 to monitor the operation on any of the operation units 6 to 15 and accept various types of settings, and also controls operations of various parts. In addition, the sub-CPU 24 controls an operation of the main CPU 21 to display the menu screen and the status on the display section 5. Moreover, the sub-CPU 24 monitors for the connection of the main apparatus, and if the main apparatus is connected, the sub-CPU 24 accepts various settings from the main apparatus, and also controls operations of various parts. Still further, the sub-CPU 24 notifies the main apparatus of the status so that the main apparatus can display the various statuses.
Specifically, the sub-CPU 24 instructs the main CPU 21 to display the menu screen in accordance with an operation on the operation unit 6. In addition, in a situation where the menu screen is displayed, the sub-CPU 24 changes the display on the menu screen and accepts various settings in accordance with operations on the operation units 7 and 10 to 13.
Here,
Here, LINK is a menu for setting a recording format of the hard disk drive 22. AUTO is a menu for selecting automatic setting, HDV is a menu for selecting a recording format of HDTV (High Definition Television), and DV is a menu for selecting a recording format of the DV system. CAM LINK TYPE is a setting menu for a coordinated operation with the main apparatus. Cache Mode is a setting menu for On/Off of the cache recording. DELETE is a menu for file deleting. LAST SHOT is a menu for deleting a file that has been recorded last, ALL is a menu for deleting all recorded files, and FORMAT is a menu for issuing an instruction for formatting. TC Format and Sleep Mode are a menu for setting a format of the time code and a menu for setting the sleep mode, respectively. G Sensor is a menu for setting as to whether the falling sensor 26 is to be used to retract the head.
The sub-CPU 24 controls the operations of various parts in accordance with the setting as specified using this menu screen. Specifically, if the recording operation unit 8 is operated in a situation where the menu screen is not displayed, the sub-CPU 24 instructs the main CPU 21 to record the data inputted via the interface 23, so that the data sequentially inputted is recorded on the hard disk drive 22. In the case where, at this time, the recording format of the hard disk drive 22 is set to AUTO by the setting specified using the menu screen, the main CPU 21 determines whether or not the data sequentially inputted is HDTV video data, and the recording format is switched in accordance with a result of this determination. Meanwhile, in the case where the recording format is set to HDV or DV, the data sequentially inputted is recorded in the recording format of the HDTV format or the DV format, respectively. In the case where this data includes the video data and the audio data and the cache recording has been set to on by the user, the main CPU 21 is controlled to carry out the cache recording. In the case where the format of the time code is set to AUTO, time code values in the video data sequentially inputted are recorded, whereas in the case where the format of the time code is set to NDF or DF, the time code values in the video data sequentially inputted are converted into a format corresponding to the setting, before being recorded.
Still further, if the stop operation unit 7 is operated during the recording, the sub-CPU 24 controls the main CPU 21 to stop the recording. In addition, the sub-CPU 24 controls the main CPU 21 to display, on the display section 5, the status such as “during recording” or “during playback,” the remaining battery life, the time code, and so on.
Still further, if the play operation unit 11 is operated in the situation where the menu screen is not displayed, the sub-CPU 24 instructs the main CPU 21 to reproduce a file that has been recorded most recently, so that the file in question recorded on the hard disk drive 22 is reproduced therefrom. In addition, the sub-CPU 24 controls the operations of various parts to output the reproduced data via the interface 23. Still further, if the fast-forward operation unit 10 or the rewind operation unit 12 is operated in a situation where a file is being played, the file being played is fast-forwarded or rewound. If the stop operation unit 7 is operated, the playing operation is controlled to stop. Still further, if the repeat play operation unit 13 is operated, the file being played is rewound by a predetermined period of time and then played from that point, so that the same portion is played repetitively.
Meanwhile, if the main CPU 21 detects the connection of the main apparatus, the sub-CPU 24 controls the main CPU 21 to establish the connection with the main apparatus. In addition, in response to a request from the main apparatus, the sub-CPU 24 provides the various menus as described above with reference to
Still further, if the operation unit 14 is operated to select the remote control by the main apparatus, the sub-CPU 24 sequentially inputs the video data and the audio data outputted from the main apparatus, and records the sequentially inputted video data and audio data in accordance with instructions from the main apparatus to start and stop the recording.

Moreover, an operation unit 70 for selecting an image quality adjustment profile and an operation unit 71 for checking various statuses are provided below the door 43.
The baseband control section 88 switches its operation in accordance with control of the GUI control section 83, and, at the time of recording the imaging result, processes the video data outputted from the camera video control section 84 and the audio data outputted from the AD/DA circuit 87, and outputs the resulting video and audio data to an HDV codec 89 or a tape deck control section 92. In addition, the baseband control section 88 displays a monitor image of the imaging result on the display section 44 and the electronic viewfinder (EVF) 30. Moreover, in a situation where the monitor image is being displayed, the baseband control section 88 presents an onscreen display of various statuses specified by the GUI control section 83. Still further, in response to an instruction from the GUI control section 83 to display the menu screen, the baseband control section 88 displays the menu screen on the display section 44 and the electronic viewfinder 30.
Meanwhile, in the case where the imaging result is reproduced for monitoring, the baseband control section 88 acquires the video data and the audio data from the HDV codec 89 or the tape deck control section 92, and displays a monitor image of the video data on the display section 44 and the electronic viewfinder 30. In this case also, in the situation where the monitor image is being displayed, the baseband control section 88 presents an onscreen display of a status specified by the GUI control section 83, and also displays the menu screen.
In the case where the imaging result is to be recorded in HDTV format, the HDV codec 89 converts the video data outputted from the baseband control section 88 into corresponding HDTV video data, and outputs the HDTV video data to an encoding/decoding section 91 together with the audio data outputted from the baseband control section 88. Meanwhile, in the case where the imaging result is reproduced for monitoring and this imaging result is recorded in HDTV format, the HDV codec 89 receives the video data and the audio data outputted from the encoding/decoding section 91, performs the inverse of the process performed at the time of recording, and outputs the resulting video and audio data to the baseband control section 88.
In the case where the imaging result is to be recorded in DV format, a DV codec 90 converts the video data outputted from the baseband control section 88 into DV format, and outputs the resulting video data to the tape deck control section 92 together with the audio data outputted from the baseband control section 88. Meanwhile, in the case where the imaging result is reproduced for monitoring and this imaging result is recorded in DV format, the DV codec 90 receives the video data and the audio data outputted from the tape deck control section 92, performs the inverse of the process performed at the time of recording, and outputs the resulting video and audio data to the baseband control section 88.
In the case where the imaging result is to be recorded in HDTV format, the encoding/decoding section 91 encodes the video data and the audio data outputted from the HDV codec 89, and outputs the resulting video and audio data to the tape deck control section 92. Meanwhile, in the case where the imaging result is reproduced for monitoring and this imaging result is recorded in HDTV format, the encoding/decoding section 91 decodes a bit stream outputted from the tape deck control section 92 to obtain corresponding video and audio data, and outputs the video and audio data to the HDV codec 89.
The tape deck control section 92 controls a magnetic tape transport system under control of a transport mechanism control section 93, and records the data outputted from the encoding/decoding section 91 or the DV codec 90 on a magnetic tape sequentially. Meanwhile, at the time of reproducing, the tape deck control section 92 reproduces the video data and the audio data from the magnetic tape, and outputs the reproduced video and audio data to the encoding/decoding section 91 or the DV codec 90.
Accordingly, in the camera-integrated video tape recorder 2, the imaging result obtained by the imaging device 81 is processed by the baseband control section 88 and displayed by the display section 44 and the electronic viewfinder 30, so that the monitor image of the imaging result is displayed. Further, in the case where the imaging result is to be recorded in HDTV format, the video data and the audio data outputted from the baseband control section 88 are processed by the HDV codec 89, the encoding/decoding section 91, and the tape deck control section 92 sequentially so as to be recorded on the magnetic tape. Still further, in the case where the imaging result is to be recorded in DV format, the video data and the audio data outputted from the baseband control section 88 are processed by the DV codec 90 and the tape deck control section 92 sequentially so as to be recorded on the magnetic tape.
Still further, in the case where the imaging result recorded on the magnetic tape is to be reproduced for monitoring and this imaging result is recorded in HDTV format, the imaging result outputted from the magnetic tape is processed by the tape deck control section 92, the encoding/decoding section 91, and the HDV codec 89 sequentially to reproduce the original video data and the original audio data, and the reproduced video data is processed by the baseband control section 88 and displayed on the display section 44 and the electronic viewfinder 30. Meanwhile, in the case where the imaging result is recorded in DV format, the imaging result outputted from the magnetic tape is processed by the tape deck control section 92 and the DV codec 90 sequentially to reproduce the video data and the audio data, and the reproduced video data is processed by the baseband control section 88 and displayed on the display section 44 and the electronic viewfinder 30.
A LINK control section 94 is an IEEE 1394 input/output circuit, and if the external device is connected thereto, the LINK control section 94 establishes connection with this external device under control of the transport mechanism control section 93 to input or output various types of data from or to the external device. In addition, the LINK control section 94 inputs or outputs video data and audio data from or to the external device, and depending on the format of the video data inputted or outputted, the LINK control section 94 transmits or receives, to or from the tape deck control section 92, the encoding/decoding section 91, or the DV codec 90, the video data and the audio data inputted or outputted from or to the external device.
The transport mechanism control section 93 is a control circuit for controlling a recording/reproducing system of the camera-integrated video tape recorder 2, and controls various parts under control of the GUI control section 83.
The GUI control section 83 is processing means that executes a program recorded on a memory (not shown), and controls an operation of the whole camera-integrated video tape recorder 2 via the camera driving control section 82 and the transport mechanism control section 93. Thus, in the camera-integrated video tape recorder 2, the program executed by the GUI control section 83 is provided by being installed in the camera-integrated video tape recorder 2 beforehand. Alternatively, the program may be provided by being recorded on a recording medium such as an optical disc, a magnetic disk, or a memory card, or may be provided by being downloaded via a network such as the Internet.
Specifically, in accordance with an operation on the operation unit 36, the GUI control section 83 displays the menu screen on the display section 44 and the electronic viewfinder 30, and accepts settings for various parts via the selection of menus on this menu screen. If the external recording apparatus 3 is not connected to the camera-integrated video tape recorder 2 at this time, the GUI control section 83 accepts only settings for the camera-integrated video tape recorder 2 via the menu screen displayed.
In response to the selection of this menu, the GUI control section 83 displays menus on a subordinate level as shown in
Meanwhile, in the case where the external recording apparatus 3 is connected to the camera-integrated video tape recorder 2, a setting for the external recording apparatus 3 is also accepted via the menu screen displayed. Thus, upon detection by the LINK control section 94 of the connection of the external device, the GUI control section 83 performs a procedure as shown in
Meanwhile, in the case where this external device is the external recording apparatus 3, the menu list is sent therefrom in response to the above request, and the GUI control section 83 acquires this menu list. Here, this menu list is a list of the menus immediately below the root, i.e., LINK, CAM LINK TYPE, Cache Mode, and so on as described above with reference to
Upon acquisition of one menu list, the GUI control section 83 notifies the external device of completion of the reception of the menu list. After the notification of the completion of the reception thereof, the external recording apparatus 3 provides notification that there is a remaining menu list if there is a menu list that remains to be transmitted, or provides notification that all menu lists have been transmitted if all the menu lists have already been transmitted.
In accordance with the notification, the GUI control section 83 continues to request and acquire menu lists until it receives all the menu lists, and when it has received all the menu lists, the GUI control section 83 finishes the procedure of

Specifically, if the user selects a lowest-level menu in connection with the external recording apparatus 3, the GUI control section 83 provides the external recording apparatus 3 with a menu ID that identifies a menu on a level superior to the selected menu and a setting value corresponding to the selected menu, receives notification that the setting has been completed from the external recording apparatus 3, and finishes this procedure. Note here that menu IDs are IDs specific to individual menu lists, and that the menu IDs are set in order of transmission in the procedure of
If the user selects the Memory menu in the menu screen displayed, the GUI control section 83 displays various setting items in connection with the recording/reproducing system to accept a selection by the user. In the case where the external recording apparatus 3 is connected to the camera-integrated video tape recorder 2 at this time, a menu (VTR KEY) for selecting a reproducing target is displayed, in addition to the other menus to be displayed, as shown in
Meanwhile, the GUI control section 83 acquires the imaging result in response to an operation on the operation unit 40, and displays the monitor image on the display section 44 and the electronic viewfinder 30. If the operation unit 39 is operated in this situation, this imaging result is recorded on the magnetic tape in the format set by the user with the menu screen. At this time, if the external device is connected to the camera-integrated video tape recorder 2 and this external device is a recording apparatus, the video data and the audio data are outputted to this external device. Further, each time the operation unit 39 is operated, the instruction to start the recording or the instruction to stop the recording is notified to the external device in response to the operation on the operation unit 39. The determination as to whether or not this external device is a recording apparatus is made based on type of the external device detected when the connection with this external device is established, for example.
As a result of the notification to the external device, the external recording apparatus 3 connected to the camera-integrated video tape recorder 2 sequentially records the imaging result on the hard disk drive 22 in accordance with the setting made with the menu screen of the camera-integrated video tape recorder 2 or the setting made with the menu screen of the external recording apparatus 3, in accordance with an operation on the operation units in the camera-integrated video tape recorder 2, in the case where the remote control by the main apparatus is selected by the operation unit 14.

Even in the case where the external recording apparatus 3 is connected to the camera-integrated video tape recorder 2, if the camera-integrated video tape recorder 2 is set as the reproducing target (see
Meanwhile, in the case where the external recording apparatus 3 is set as the reproducing target in the situation where external recording apparatus 3 is connected to the camera-integrated video tape recorder 2, the GUI control section 83 notifies the external recording apparatus 3 of the operation performed on any of the operation units 55 to 59, and remotely controls the external recording apparatus 3 to reproduce the video data and the audio data recorded on the hard disk drive 22. In addition, the GUI control section 83 acquires the reproduced video data and audio data, and displays the monitor image.
If the user operates the operation unit 71 in a situation where the monitor image is being displayed at the time of recording/reproducing, the GUI control section 83 displays various statuses of the camera-integrated video tape recorder 2. In addition, the GUI control section 83 causes page turning sequentially on this display in accordance with the operation on the operation unit 37.
At this time, in the case where the external recording apparatus 3 is connected to the camera-integrated video tape recorder 2, the GUI control section 83 requests the external recording apparatus 3 to provide the notification of the status at regular intervals, to acquire the status of the external recording apparatus 3. In addition, as illustrated in
The camera-integrated video tape recorder 2, which forms a part of the recording/reproducing system 1 with the above-described structure, can be used on its own, and in that case, the imaging result obtained by the imaging device 81 is processed by the camera video control section 84 and displayed on the display section 44 and the electronic viewfinder 30 via the baseband control section 88, so that the imaging result is displayed thereon for monitoring (
Further, in response to an operation on the menu operation unit 36, the menu screen is displayed on the display section 44 and the electronic viewfinder 30 (FIG. 7), and if a menu on the menu screen is selected, the format of the video data and the audio data to be recorded on the magnetic tape is set, for example. In the case where they are to be recorded in HDV format, for example, the video data and the audio data outputted from the baseband control section 88 are processed by the HDV codec 89 and the encoding/decoding section 91 sequentially and recorded on the magnetic tape. Meanwhile, in the case where they are to be recorded in DV format, the video data and the audio data outputted from the baseband control section 88 are processed by the DV codec 90 and recorded on the magnetic tape.
Further, in accordance with an operation on the operation units 55 to 59 and so on in connection with reproducing processing, the imaging result recorded on the magnetic tape is reproduced by the tape deck control section 92 and processed by the encoding/decoding section 91 and the HDV codec 89 sequentially, or by the DV codec 90, and then inputted to the baseband control section 88. The imaging result inputted to the baseband control section 88 is displayed on the display section 44 and the electronic viewfinder 30, so that the user can monitor the imaging result recorded on the magnetic tape.
Still further, if the operation unit 71 for checking the status is operated in a situation where the monitor image of the imaging result is being displayed, an onscreen display of various statuses of the camera-integrated video tape recorder 2 is presented on the display section 44 and the electronic viewfinder 30, and in response to an operation on the operation unit 37, the onscreen display is subjected to the page turning to allow the user to check the remaining battery life, the various settings at the time, and so on, for example (
On the other hand, the external recording apparatus 3 is connected to various types of video equipment to receive the video data and the audio data therefrom, and in response to an operation on the operation unit 8, the video data and the audio data inputted thereto sequentially are processed by the main CPU 21 and recorded on the hard disk drive 22 (
Accordingly, it is possible to use the external recording apparatus 3 for the recording and reproducing of the video data and the audio data, by connecting it to various types of video equipment that input and output the video data and the audio data. However, the smaller the external recording apparatus 3 is, the harder the operation of the operation units will become. Thus, making various settings by operating the operation units will become more cumbersome, and the operation for the recording or reproducing will also become more cumbersome, resulting in a reduction in usability. In addition, when checking the status such as the remaining battery life, it is necessary to take the trouble to view the small display section 5 provided on the external recording apparatus 3 in order to check it, resulting in a reduction in usability. In particular, in the external recording apparatus 3, the operation units 10 to 12 are used for both the operation of selecting a menu on the menu screen and the operation of reproducing the data recorded on the hard disk drive 22, and thus they not only have poor usability but also they are likely to be operated erroneously because of the small size.
As such, in the recording/reproducing system 1 including the camera-integrated video tape recorder 2 and the external recording apparatus 3 connected thereto (
Further, if the user operates the operation unit 36 in the camera-integrated video tape recorder 2 to issue the instruction to display the menu screen, the menu screen is displayed on the camera-integrated video tape recorder 2, while the menu representing the external device is added as an uppermost-level item in the menu screen (
Therefore, in this case, various settings for the external recording apparatus can be made only by performing operations on the part of the camera-integrated video tape recorder 2 as the main apparatus, with no need to operate the external recording apparatus 3. Thus, even in the case where the external recording apparatus is designed to be small and capable of being connected to various types of video equipment and is equipped with various types of operation units, an alarm display section, and so on, it is possible to effectively avoid a reduction in usability of the external recording apparatus when it is connected to a main unit.
In particular, in the camera-integrated video tape recorder 2, the menu screen is displayed while the menus acquired from the external recording apparatus 3 are added to the menus displayed on the camera-integrated video tape recorder 2. Therefore, the user is able to make various settings for the external recording apparatus 3 at the same time when making settings for the camera-integrated video tape recorder 2, with a unified and the same operation as when the user makes various settings for the camera-integrated video tape recorder 2. Accordingly, when they are viewed as the recording/reproducing system 1, the user is able to make various settings for the external recording apparatus 3 without distinguishing between the main apparatus and the external recording apparatus. Thus, an improvement in usability is achieved.
Still further, if the imaging result is to be recorded in HDTV format in accordance with the settings in the menu screen in the camera-integrated video tape recorder 2 in a situation where the external recording apparatus 3 is connected to the camera-integrated video tape recorder 2 and the imaging result is being displayed on the display section 44 and the electronic viewfinder 30, a bit stream composed of the video data and the audio data outputted from the encoding/decoding section 91 is outputted to the external recording apparatus 3 via the LINK control section 94. Meanwhile, if the imaging result is to be recorded in DV format, a bit stream composed of the video data and the audio data outputted from the DV codec 90 is outputted to the external recording apparatus 3 via the LINK control section 94. Still further, if the user operates the operation unit 39 to issue the instruction to start or stop the recording of the imaging result, the instruction to start or stop the recording is notified to the external recording apparatus 3 via the LINK control section 94.
In the case where the remote control by the main apparatus is selected in the external recording apparatus 3 as a result of the operation on the operation unit 14, the bit stream composed of the video data and the audio data outputted from the camera-integrated video tape recorder 2 is recorded on the hard disk drive 22, or this recording is stopped, in accordance with the above instruction to start or stop the recording. Accordingly, in this case, it is possible to record the imaging result in accordance with the operation on the operation unit 39 in the camera-integrated video tape recorder 2, without the need to operate any operation unit in the external recording apparatus 3. This also contributes to effectively avoiding a reduction in usability of the external recording apparatus when it is connected to the main unit.
Meanwhile, if the operation units 55 to 59 in connection with the reproducing are operated in the camera-integrated video tape recorder 2 when the external recording apparatus 3 is set as the reproducing target in the menu screen (
Still further, in the case where the external recording apparatus 3 is connected to the camera-integrated video tape recorder 2, the camera-integrated video tape recorder 2 acquires the status of the external recording apparatus 3 at regular intervals, and if the user operates the operation unit 71 to issue the instruction to display the status, the status of the external recording apparatus 3 is displayed together with the status of the camera-integrated video tape recorder 2.
Therefore, according to the recording/reproducing system 1, the user is able to check the status of the external recording apparatus 3 together with the status of the camera-integrated video tape recorder 2, without the need to take the trouble to check the status displayed on the display section 5 of the external recording apparatus 3. This also contributes to effectively avoiding a reduction in usability of the external recording apparatus when it is connected to the main unit.
According to the above-described structure, in the case where the external recording apparatus is connected to the main apparatus, the menus for the external recording apparatus are provided to the main apparatus, and the settings for the external recording apparatus are accepted with the main apparatus. Because of this, even in the case where the external recording apparatus is designed to be small and capable of being connected to various types of video equipment and is equipped with various types of operation units, the alarm display section, and so on, it is possible to effectively avoid a reduction in usability of the external recording apparatus when it is connected to the main unit.
In the above-described embodiment in particular, the main apparatus is the camera-integrated video tape recorder that records and reproduces the video data and the audio data, and therefore, it is possible to display the menu screen for the external recording apparatus on the display section that is used to display the monitor image of the video data, so as to accept various settings therewith. Thus, a further improvement in usability is achieved.
Moreover, the operations on the operation units for the recording/reproducing in the main apparatus are notified to the external recording device to control processing for the recording/reproducing in the external recording apparatus. Therefore, the reduction in usability can be avoided effectively, even in connection with the operation for the recording/reproducing.
Still further, the main apparatus acquires the status of the external recording apparatus from the external recording apparatus, and displays the acquired status on the display section of the main apparatus. Therefore, the reduction in usability can be avoided effectively, even in connection with the checking of the status.
In the above-described embodiment, the camera-integrated video tape recorder is adopted as the main apparatus. Note, however, that the present invention is not limited to that case, but is also applicable to a wide variety of cases where the external recording apparatus is connected to various types of video equipment, other than the camera-integrated video tape recorder, that input and output the video data and the audio data.
The present invention is applicable to a system that includes a camera-integrated video tape recorder and an external recording apparatus connected to the camera-integrated video tape recorder, for example.
