  FIG. 3 is a diagram showing an example of a recording / reproducing system to which the present invention is applied.

  301 is an A camera having the configuration of the video camera 100 of FIG. 1, 302 is a B camera having the configuration of the video camera 100 of FIG. 1, 303 is an A deck having the configuration of the video recorder deck 200 of FIG. 2, and 304 is an A camera. 301, a removable disk 305 which is a recording medium that can be used in common between the B camera 302 and the A deck 303, is a diagram showing the contents recorded on the removable disk 305.

  In the configuration of FIG. 3, the control operation by the main microcomputer 111 in the recording mode by the A camera 301 and the B camera 302 will be described with reference to the flowchart shown in FIG.

  The recording devices have device IDs indicating the individual devices of “CA00000001”, “CA00000002”, and “DK00000001”, respectively.

  When the disk 304 is inserted into the main body by the user after the power is turned on, the disk I / F 104 recognizes the disk and analyzes the contents of the data recorded on the disk (S402). This process is performed to confirm the content and file name of a file already recorded on the disc, and to determine the file name of a file to be created when recording is performed next.

  Next, when an instruction to start recording is given by the operation key 110 (S402), the image signal obtained from the imaging unit 1012 and the audio signal obtained from the microphone 102 are encoded by the MPEG codec 103, and the disc I / F 104 discs the disc. Recording is started on D (S403). When there is an instruction to stop recording, recording of MPEG data to the disk is stopped (S404). Then, the device ID is recorded in the file management area of the disk D together with the file information of the MPEG data just recorded. In this embodiment, the MPEG data recorded between the recording start instruction and the recording stop instruction is recorded as one file, and the main microcomputer 111 records the recording position of each file recorded on the disk D and the like. Management information including a file name, thumbnail image data of each file, recorded device ID, and the like is generated and recorded in the management information area on the disk D by the disk I / F 104.

  The processing at the time of recording in the deck A 303 is almost the same as the processing of the video camera 100 according to the flow of FIG. 4, but the main microcomputer 210 receives an instruction to start recording from the operation key 208 or the remote control sensor 209. The difference is that the image and audio signals from the tuner 201 or the image input / output unit 202 and the audio input / output unit 203 are encoded by the MPEG codec 205 and recorded on the disk. In addition, the user records either an image or sound from the tuner 202, and an image or sound signal from an external device (for example, a conventional analog VTR) connected to the image input / output unit 202 or the sound input / output unit 2032. It can be arbitrarily selected. Further, the main microcomputer 210 records the ID information of the A deck 303 added to the management information.

  Next, the process when the A camera 301 or the B camera 302 reproduces the disk 304 in which MPEG data is recorded and used in common by the A camera 301, the B camera 302, and the A deck 303 in this way is shown in FIG. This will be described with reference to the flowchart shown in FIG.

  FIG. 5 is a flowchart showing processing at the time of reproduction by the main microcomputer 111 in the video camera 100 of FIG. 1 as the A camera 301 and the B camera 302.

  After the power is turned on, when the user inserts the removable disk 304 into the main body, the disk I / F 104 recognizes the disk, reads management information recorded on the disk, and writes it to the EEPROM 112 (S501). And the data content is confirmed based on this management information. The thumbnail image data included in the management information is written in the memory 109.

  Next, when it is detected that the index display key is pressed (S502), the file order is sorted based on the management information (S503). Next, the contents of the management information are confirmed in the sort order (S504), and the device ID indicating the device recording each file is extracted from the management information (S505).

  Next, the thumbnail image data of the designated file stored in the memory 109 is read and sent to the display driver 108 (S506). Then, it is detected whether or not the device ID detected in S505 matches the device ID of the main body of the device performing this operation (S507). If they match, the thumbnail image is displayed in the index screen. The display driver 108 is controlled so as to be enlarged to a predetermined size (S508). The display driver 108 has a RAM for generating a display screen inside, and the thumbnail image is enlarged and written to an address on the RAM corresponding to the display position on the index screen. If they do not match, the thumbnail image is not enlarged and placed on the RAM in its normal size (S509).

  Next, it is detected whether a predetermined number of thumbnail images to be displayed on one screen have been written on the RAM or there are no more files to be read (S510). The same processing is repeated for the thumbnail image of the file (S515).

  Next, when processing of thumbnail images to be displayed on one screen is completed, an index screen is displayed on the display 107 by the display driver 108.

  In this state, when one of the thumbnail images on the index screen is selected by the user and there is an instruction to start playback (S512), playback of the data of the file selected by the disk I / F 104 is started, and the MPEG codec 103 is started. Is decoded and sent to the display driver 108. The display driver 108 displays the reproduced image data on the display 107 instead of the index screen in response to an instruction to start reproduction. When an instruction to stop playback is given, the disk I / F 104 is controlled to stop playback of the file.

  Note that the processing in the playback mode in the A deck 303 is almost the same as the processing of the video camera 200 according to the flow of FIG. 5, but in the deck 200 of FIG. In step 214, an index screen is generated. The index screen is output to the TV monitor by the image input / output unit 202. When an instruction to start playback is given, the image input / output unit 202 outputs a playback image to the TV monitor, and the audio input / output unit 203 outputs playback sound.

  FIG. 6 is a diagram showing the state of the index screen of the disc 304 on which the content 305 shown in FIG. 3 is recorded by the series of processing shown in FIGS.

  Reference numeral 601 denotes an index screen when the A camera 301 reproduces the disc 304. Among the contents recorded on the disc 304, thumbnail images indicating “C” and “E”, which are contents recorded by the A camera 301 itself, are displayed. It is displayed in a size larger than other thumbnail images. Reference numeral 602 denotes an index screen when the disc 304 is reproduced by the B camera 302, and indicates “A” and “F”, which are the contents recorded by the B camera 302 itself among the contents recorded on the disc 304. The thumbnail image is displayed in a larger size than other thumbnail images. Further, reference numeral 603 denotes an index screen when the disc 304 is played back on the A deck 303, and shows “B” and “D” which are contents recorded on the A deck 303 itself among the contents recorded on the disc 304. The thumbnail image is displayed larger than the other thumbnail images.

  In this way, in this embodiment, when displaying the index screen of a disc that is used in common among a plurality of devices, the size of the thumbnail image of the content recorded by the currently playing device is compared with the thumbnail image of the other content. The large display allows the user to easily recognize the content recorded by the device currently being played.

  In this embodiment, it is possible to adopt a configuration in which editing or deletion of the file is permitted only when the device ID detected from the management information matches the ID of the main body. In this case, as shown in FIG. 7, a mark indicating that, for example, a key mark, is displayed in the vicinity of a thumbnail image other than the thumbnail image that is displayed in an enlarged manner to clearly indicate that editing or deletion cannot be performed. Also good.

  In this embodiment, the device ID recorded as the disc management information is recorded. However, the disc ID and file name information are recorded on the recording device side and stored in the device and the ID detected from the disc during playback. The index screen may be displayed as described above by collating the disc IDs.

<< Second Embodiment >>
A second embodiment will be described with reference to the drawings.

  The block diagram on the disc video camera side in this embodiment and the block diagram on the disc video recorder deck side in this embodiment are the same as the block diagrams shown in FIGS. 1 and 2 of the first embodiment.

  FIG. 8 is a diagram showing an example of the recording / reproducing system of the present invention. 801 is a C camera having the configuration of the video camera 100 of FIG. 1, 802 is a B deck having the configuration of the video recorder deck 200 of FIG. 2, and 803 is a recording medium that can be used in common between the C camera 801 and the B deck 802. A removable disk 804 is a diagram showing the contents recorded on the removable disk 803.

  The operation of the recording mode in the C camera 801 and the B deck 802 with the configuration of FIG. 8 will be described with reference to the flowchart shown in FIG.

  The recording device has a source ID indicating a video input source of “CAM001” for camera input, “TUN001” for tuner input, “AIN001” for analog external input, and “DIN001” for digital external input. .

  When the disk 803 is inserted into the main body by the user after the power is turned on, the contents of the disk are confirmed (S901). Next, when there is an instruction to start recording, the file name is determined and recording is started (S903). When there is an instruction to stop recording (S904), recording of MPEG data is stopped and management information including the source ID is recorded in the file management area of the disc (S905). In this embodiment, since the video camera 100 of FIG. 1 has only the imaging unit 101 as a source of image data, a camera input ID is added as a source ID. In the deck 200 of FIG. 2, there are three image data sources: a tuner 201, an analog input from the image input / output unit 202, and a digital input from the digital I / F 204. You can choose any source. The main microcomputer 210 adds an ID corresponding to the selected image source to the management information and records it.

It is detected (S1005).

  Next, the thumbnail image data of the designated file is reproduced (S1006), and it is detected whether or not the detected source ID matches the source ID of the current priority reproduction mode (S1007). Here, the priority playback mode is a mode in which the user can set which of the above-mentioned multiple sources the image data recorded by the user is to be played back with priority.

  If the source ID matches the ID of the priority playback mode in S1007, the size of the thumbnail image of this file is enlarged to a predetermined size and placed on the RAM in the display driver 108. If they do not match, the thumbnail image is placed on the RAM as it is without being enlarged. Next, it is detected that the number of thumbnail images arranged on the RAM has reached a predetermined number of pages or that there are no more files to be read, and if there are still thumbnail images to be displayed, the next file is designated. Then, the same processing is repeated. If there is no thumbnail image to be displayed, the generated index screen is displayed (S1011).

  In this state, when one of the thumbnails displayed on the index screen is selected and a reproduction start instruction is issued (S1012), reproduction of the selected file is started (S1013), and a reproduction stop instruction is issued. The reproduction is stopped and finished (S1014).

  FIG. 11 is an example of an index screen of the disc 803 on which the content 804 shown in FIG. 8 is displayed, which is displayed by the processing of FIGS. 9 and 10.

  Reference numeral 1101 denotes an index screen when the disc 803 is reproduced by the C camera 801. Since the C camera 801 has only a camera as an image input source, the file in which the camera image is recorded is preferentially reproduced in the reproduction mode. At this time, among the contents recorded on the disk 803, thumbnail images indicating “c” and “e” whose input source is a camera are enlarged and displayed.

  Reference numerals 1102 to 1104 denote index screens when the disc 803 is reproduced on the B deck 802. The B deck 802 has a TV tuner, analog external input, and digital external input as image input sources, and there are a TV recording / playback mode, an analog input recording / playback mode, and a digital input recording / playback mode, respectively.

  Reference numeral 1102 denotes an example of an index screen in the TV recording / playback mode. Among the contents recorded on the disc 803, thumbnail images showing “a” and “f” whose input source is the TV tuner are enlarged and displayed. Reference numeral 1103 denotes an example of an index screen in the analog input recording / playback mode. Among the contents recorded on the disc 803, a thumbnail image indicating “d” whose input source is analog input (line input) is enlarged and displayed. . Reference numeral 1104 denotes an example of an index screen in the digital input recording / playback mode. Among the contents recorded on the disc 803, a thumbnail image indicating “b” whose input source is digital input is enlarged and displayed.

  In this way, in this embodiment, when displaying an index screen of a disc that is commonly used among a plurality of devices, the size of the thumbnail image of the content from the specified source among the image sources of each file is changed to other content. By displaying the thumbnail image larger than the thumbnail image, the user can easily recognize the content recorded from the designated source.

  In this embodiment, it is also possible to adopt a configuration in which editing or deletion of the file is permitted only when the source ID detected from the management information matches the ID of the main body. In this case, as shown in FIG. 12, a mark indicating that fact, for example, a key mark, is displayed in the vicinity of the thumbnail image other than the thumbnail image that is displayed in an enlarged manner to clearly indicate that editing or deletion cannot be performed.

The current source ID is compared (S2003). Then, it waits for an instruction to start playback (S2004), and if there is an instruction to start playback, it determines whether there is a playlist file with a matching source ID (S2005).

  When a playlist file having a matching ID is recorded, the playlist file with the matching ID is reproduced from the disc, the disc I / F 104 is controlled according to the playlist, and the specified file is Playback from the disc (S2006). On the other hand, if a playlist with the same source ID has not been recorded, the files are reproduced in a predetermined order (S2007). If there is an instruction to stop playback, playback is stopped (S2008).

  As described above, in this embodiment, when an image file is recorded, a playlist to which an ID corresponding to the source of the recorded image data is added is generated, and at the time of reproduction, the selected source ID is added to the playlist. Since an image file is automatically played back based on this, when playing a disc that is commonly used among multiple devices, it is possible to automatically play back an image file recorded from a specific source, which is easy to use. .
