  A recording control method or program according to one aspect of the present invention captures content recorded on a recording medium attached to an external device by causing the external device to reproduce the content, and stores the captured content in a predetermined recording medium. When there are contents in a plurality of formats as contents that can be recorded and taken in from the external device, only the contents in the first mode that takes in the contents in all formats and the contents in a predetermined format among the plurality of formats Including a step (for example, step S5 in FIG. 8) of accepting a user's operation for selecting any one of the second modes for capturing the image.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration example of a recording control system including a recording control apparatus 1 according to an embodiment of the present invention.

  As shown in FIG. 1, the recording control system includes, for example, a recording control device 1, a video camera 2, and a playback device 3.

  The recording control device 1 and the video camera 2, and the recording control device 1 and the playback device 3 are connected via an IEEE1394 cable. The video camera 2 and the playback device 3 are external devices of the recording control device 1 and operate according to control by the recording control device 1.

  As shown in FIG. 2, the recording control apparatus 1 is used when contents recorded on a plurality of tapes are grouped together on a single tape for each time code. In the example of FIG. 2, the content recorded on the tapes A to C attached to the external devices such as the video camera 2 and the playback device 3 serving as the player side devices becomes the recording control device 1 serving as the recorder side device. It is dubbed on a single tape attached to the tape.

  As shown in FIG. 1, the recording control apparatus 1 is provided with a tape mounting portion 11 on which a tape of a predetermined standard can be mounted, and a tape as a content dubbing destination is mounted on the tape mounting portion 11. Is done. The recording control device 1 is also provided with a display unit 12 made of an LCD (Liquid Crystal Display) or the like on the surface of the casing.

  In this way, by causing the external device to perform playback, the content is taken into the recording control device 1 from the dubbing source tape attached to the external device, and the captured content is dubbed to the recording control device 1. When recording on a tape, the user can capture content in all formats recorded on the dubbing source tape, and mode that captures and records only the content in a predetermined format. One of the modes can be selected.

  The video camera 2 is a video camera that supports recording of a plurality of formats such as HDV format, DVCAM format, DV SP format, etc. When shooting is performed by switching the format, a plurality of tapes are attached to the video camera 2. Content of the format will be mixed. In addition, since the playback device 3 is loaded with a tape or the like recorded by the video camera 2 and recorded with content, content in a plurality of formats may be mixed on the tape played back by the playback device 3.

  FIG. 3 is a diagram illustrating an example of a screen displayed on the display unit 12 of the recording control apparatus 1 when the content capture mode is selected.

  For example, the recording control device 1 and an external device are connected by an IEEE1394 cable, and a dubbing destination tape is attached to the tape mounting portion 11 of the recording control device 1 and a dubbing source tape is attached to the external device, and a predetermined operation is performed. Sometimes the screen of FIG. 3 is displayed.

  In the example of FIG. 3, “FORMAT SEL” is displayed on the right side of the screen, and “ALL”, “HDV1080i”, “DVCAM”, “DV SP” are displayed as characters indicating selectable modes below that. Is displayed. The user moves the cursor C by operating the upper and lower buttons of the cross key provided on the surface of the casing of the recording control apparatus 1, and selects the mode to which the cursor C is applied at that time by pressing the enter key. Can do.

  FIG. 4 shows the operation of the recording control apparatus 1 when “ALL”, “HDV1080i”, “DVCAM”, and “DV SP” displayed as a list of selectable modes are selected.

  "ALL" is HDV1080i format content (content including HD (High Definition) images with a horizontal scanning line number of 1080 and scanning method of interlace) recorded on a tape attached to an external device as a player, This is a mode in which DVCAM format content, DV SP format content, that is, content in all formats is played back by an external device. In this example, there are three types of content formats that can be dubbed by the recording control apparatus 1: HDV1080i format, DVCAM format, and DVSP format.

  In the example of FIG. 4, “ALL” is selected as the content capture mode, and the content (in HDV720p format, which is content that cannot be dubbed by the recording control apparatus 1), although the content is in HDV format on the dubbing source tape. In the case of recording 720 horizontal scanning lines and content that includes a progressive HD image), no signal is recorded at the dubbing destination tape position corresponding to the recording position. Yes.

  Further, when DV LP format content that is content that cannot be dubbed by the recording control apparatus 1 is recorded on the dubbing source tape, the dubbing destination tape corresponding to the recording position is recorded. In this position, DV LP format content captured from an external device is converted to DV SP format content and recorded.

  “HDV1080i” is a mode in which only content in the HDV1080i format recorded on a tape attached to an external device that is a player is played back and captured by the external device.

  When “HDV1080i” is selected as the content capture mode and content in a format other than the HDV1080i format is recorded on the dubbing source tape, the recording position is fast-forwarded (skipped) according to the control by the recording control device 1, Content in a format other than the HDV1080i format is not captured by the recording control apparatus 1.

  “DVCAM” is a mode in which only content in the DVCAM format recorded on a tape attached to an external device that is a player is played back and captured by the external device.

  When “DVCAM” is selected as the content capture mode and content in a format other than the DVCAM format is recorded on the dubbing source tape, the recording position is fast-forwarded according to control by the recording control device 1 and is not in the DVCAM format. The content of the format is not taken into the recording control apparatus 1.

  “DV SP” is a mode in which only the content in the DV SP format recorded on the tape attached to the external device as a player is played back and captured by the external device.

  When “DV SP” is selected as the content capture mode and content in a format other than the DV SP format is recorded on the dubbing source tape, the recording position is fast-forwarded according to control by the recording control device 1, and DV SP Content in a format other than the format is not taken into the recording control apparatus 1.

  These “HDV1080i”, “DVCAM”, and “DV SP” are the above-described “modes for capturing and recording only content in a predetermined format”.

  FIG. 5 shows an example of dubbing performed when a mode for capturing contents of all formats recorded on the dubbing source tape is selected, that is, when “ALL” is selected from the screen of FIG. FIG.

  In the example of FIG. 5, HDV1080i format content, DVCAM format content, DVSP format content, and no signal are recorded in chronological order on a dubbing source tape attached to an external device. In FIG. 5, the horizontal direction represents the time direction.

  In this way, when content of multiple formats is recorded on the dubbing source tape, the format change point and the format type of the content recorded at each position are controlled from the external device by IEEE1394 communication. This is determined from the system mode and track pitch information notified to the apparatus 1.

  The content recorded on the dubbing source tape is the HDV format content of HDV1080i, HDV720p, or HDV480p, and the content recorded on the dubbing source tape is the HDV format or DV format. Whether the content is in the format is determined by the system mode.

  Further, it is determined by the track pitch which DV format, DVCAM, DV SP, or DV LP, is the content recorded on the dubbing source tape.

  For example, if the content in the format as shown in the upper part of FIG. 5 is recorded on the dubbing source tape and “ALL” is selected as the capture mode, the recording control device as shown in the lower part of FIG. According to the control by No. 1, the content is played back by an external device in the order of content in HDV1080i format, content in DVCAM format, and content in DV SP format. The reproduced content is taken into the recording control device 1 via the IEEE1394 cable and recorded on the dubbing destination tape.

  Further, in this case, the position of the dubbing source tape where no signal is recorded is fast-forwarded, and no signal is not taken into the recording control device 1.

  FIG. 6 is a diagram illustrating an example of dubbing performed when a mode for capturing only content in a predetermined format is selected. Here, it is assumed that “HDV1080i” is selected from the screen of FIG.

  In the example of FIG. 6, HDV1080i format content, DVCAM format content, DV SP format content, no signal, and HDV1080i format content are recorded in chronological order on the dubbing source tape attached to the external device. Yes. In FIG. 6, the horizontal direction represents the time direction. The format change point and the format type of the content recorded at each position are determined from the system mode and track pitch information notified from the external device to the recording control apparatus 1 by IEEE1394 communication.

  For example, when the content in the format as shown in the upper part of FIG. 6 is recorded on the dubbing source tape and “HDV1080i” is selected as the capture mode, as shown in the lower part of FIG. According to the control by 1, the content in the HDV1080i format recorded at the top position in time is reproduced by the external device. The reproduced content in the HDV1080i format is taken into the recording control device 1 via the IEEE1394 cable and recorded on the dubbing destination tape.

  When playback of the HDV1080i format content is finished, the DVCAM format content, DV SP format content, and the position of the dubbing source tape on which no signal is recorded are fast-forwarded, and these contents are taken into the recording control device 1. Absent.

  When the fast-forwarding of the dubbing source tape is completed up to the position where no signal is recorded, the content recorded in the next HDV1080i format is reproduced by the external device according to the control by the recording control device 1. The reproduced content in the HDV1080i format is taken into the recording control device 1 via the IEEE1394 cable and recorded on the dubbing destination tape.

  By repeating such processing, only the content in the HDV1080i format is continuously recorded on the dubbing destination tape as shown in the lower part of FIG.

  As described above, the user can record the contents of all formats recorded on the dubbing source tape on the dubbing destination tape by selecting “ALL”.

  In addition, by selecting “HDV1080i”, the user can record only the content in the HDV1080i format recorded on the dubbing source tape on the dubbing destination tape. As a result, it is possible to prevent inconvenience for the editor due to a mixture of contents in a plurality of formats on one tape.

  The operation of the recording control apparatus 1 that performs dubbing by controlling an external device will be described in detail later.

  FIG. 7 is a block diagram illustrating a configuration example of the recording control apparatus 1.

  The main microcomputer 21 (main microcomputer 21) controls the sub-microcomputer 22 (sub-microcomputer 22) and the baseband block 37, and controls the overall operation of the recording control apparatus 1. Various operations of the user using a cross key or a determination key provided on the surface of the casing of the recording control device 1 are accepted by the main microcomputer 21.

  For example, the main microcomputer 21 controls the sub-microcomputer 22 to fetch content from the video camera 2 or the playback apparatus 3 connected to the recording control apparatus 1 via an IEEE1394 cable.

  The sub-microcomputer 22 controls the IEEE1394 I / F 31, the tape drive unit 33, the HDV MUX / DEMUX 34 (HDV multiplexer / demultiplexer 34), the HDV codec 35, and the DV codec 36 according to the control by the main microcomputer 21. For example, the sub-microcomputer 22 causes the IEEE1394 I / F 31 to take in content from an external device, transfer the taken content to the tape drive unit 33, and transfer it to the dubbing destination tape loaded in the tape loading unit 11. Let me record.

  In addition, the sub-microcomputer 22 has a function of processing HDV format content realized by the HDV MUX / DEMUX 34 and the HDV codec 35 and a function of processing DV format content realized by the DV codec 36. Switching according to the format of the content to be processed. For example, when content in HDV format is captured from an external device, the sub-microcomputer 22 controls the HDV MUX / DEMUX 34 and the HDV codec 35 to process the content, and DV format content such as DVCAM and DV SP is processed. When captured from an external device, the DV codec 36 is controlled to process the image.

  The IEEE1394 I / F 31 generates an AV / C command (AV / C Digital Interface Command Set) under the control of the sub-microcomputer 22, the video camera 2 connected via the IEEE1394 cable attached to the IEEE1394 terminal 32, playback Control external devices such as the device 3. The IEEE1394 I / F 31 outputs the HDV format content captured from the external device to the HDV MUX / DEMUX 34, and outputs the DV format content captured from the external device to the DV codec 36. Further, when data is supplied from the HDV MUX / DEMUX 34 and the DV codec 36, the IEEE1394 I / F 31 outputs the supplied data to an external device.

  The tape drive unit 33 controls the tape mounted on the tape mounting unit 11, outputs the HDV format content captured from the tape to the HDV MUX / DEMUX 34, and converts the DV format content captured from the tape to the DV codec 36. Output to. Further, when data is supplied from the HDV MUX / DEMUX 34 and the DV codec 36, the tape drive unit 33 records the supplied data on the tape.

  The HDV MUX / DEMUX 34 generates a stream from the HDV format data encoded by the HDV codec 35 under the control of the sub-microcomputer 22, and outputs the generated stream to the IEEE1394 I / F 31 and the tape drive unit 33. The HDV MUX / DEMUX 34 extracts a predetermined packet from the stream supplied from the IEEE1394 I / F 31 according to control by the sub-microcomputer 22 and outputs the extracted packet to the HDV codec 35.

  Further, the HDV MUX / DEMUX 34 is fetched from the external device by the IEEE1394 I / F 31, and the supplied content stream is output to the tape driving unit 33 and recorded on the tape mounted on the tape mounting unit 11.

  The HDV codec 35 encodes the data supplied from the baseband block 37 as HDV format data under the control of the sub-microcomputer 22, and outputs the encoded data to the HDV MUX / DEMUX 34. Further, the HDV codec 35 decodes the data supplied from the HDV MUX / DEMUX 34 under the control of the sub-microcomputer 22 and outputs the data obtained by the decoding to the baseband block 37.

  The DV codec 36 encodes the data supplied from the baseband block 37 as DV format data under the control of the sub-microcomputer 22, and sends the data obtained by the encoding to the IEEE1394 I / F 31 or the tape drive unit 33. Output. Further, the DV codec 36 decodes the data supplied from the IEEE1394 I / F 31 and the tape drive unit 33 under the control of the sub-microcomputer 22, and outputs the data obtained by the decoding to the baseband block 37.

  Further, the DV codec 36 is fetched from the external device by the IEEE1394 I / F 31, and the supplied content is output to the tape driving unit 33 and recorded on the tape mounted on the tape mounting unit 11.

  The baseband block 37 controls display on the display unit 12 according to control by the main microcomputer 21 and outputs data obtained by performing predetermined processing on the supplied data to an external device. For example, the baseband block 37 causes the display unit 12 to display a capture mode selection screen as shown in FIG.

  The baseband block 37 also displays an image on an external monitor connected to an S terminal 38, a D terminal 39, and an HDMI (High-Definition Multimedia Interface) terminal 40.

  The power supply microcomputer 41 controls the supply of power to each part of the recording control apparatus 1.

  Here, with reference to FIG. 8, the process of the recording control apparatus 1 that performs dubbing by controlling an external device will be described.

  This process is started, for example, when a predetermined mode is selected from the capture mode selection screen displayed on the display unit 12 and a predetermined operation for starting dubbing is performed by the user.

  In step S1, the main microcomputer 21 receives a start operation by the user and activates the dubbing function. Here, the user selects whether to perform dubbing after rewinding the dubbing source and dubbing destination tapes.

  When the user selects to perform dubbing after rewinding the dubbing source and dubbing destination tapes, the process proceeds to step S2, and the main microcomputer 21 controls the sub-microcomputer 22 to transfer the dubbing source to the external device as a player. The tape is rewound, and the dubbing destination tape mounted on the tape mounting portion 11 is rewound. Under the control of the sub-microcomputer 22, an AV / C command that instructs the external device to rewind the tape is output from the IEEE1394 I / F 31, and the tape drive unit 33 rewinds the tape.

  In FIG. 8, the letter “P” shown in the frame representing each step represents an external device that is a player, and the letter “R” represents the recording control device 1 that is a recorder.

  When dubbing is not selected after rewinding the dubbing source and dubbing tape in the state of step S1, or when rewinding of the dubbing source and dubbing tape is completed in step S2, the process is as follows. Proceed to step S3.

  In step S <b> 3, the main microcomputer 21 controls the sub-microcomputer 22 to change the state of the external device to the playback pause state and to change the recording state by the tape drive unit 33 to the recording pause state. At this time, the main microcomputer 21 causes each unit to prepare for dubbing. For example, information on the capture mode selected by the user is notified from the main microcomputer 21 to the sub-microcomputer 22.

  When the preparation for dubbing is completed, the process proceeds to step S4, where the main microcomputer 21 controls the sub-microcomputer 22 to cause the external device to play back the content recorded on the dubbing source tape and also to IEEE1394 I / F 31. The content captured by is recorded on the dubbing destination tape.

  That is, an AV / C command for instructing the external device to play back content is output from the IEEE1394 I / F 31, and the content supplied from the external device via the IEEE1394 cable in response to the execution of this command It is taken in by I / F31. The content captured by the IEEE1394 I / F 31 is output to the HDV MUX / DEMUX 34 and DV codec 36 according to the format, and is output to the tape drive unit 33 via the HDV MUX / DEMUX 34 and DV codec 36. The content output to the tape drive unit 33 is recorded in the playback order on the dubbing destination tape mounted on the tape mounting unit 11.

  When no signal is detected by, for example, IEEE1394 I / F 31 based on information notified from the external device in the state of step S4 in which such dubbing is performed, or a format designated by the user as a format to be captured When a content other than is detected, the process proceeds to step S5.

  When “ALL” is selected as the capture mode, content other than the specified format is detected when content in HDV1080i format content, DVCAM format content, DV SP format, or DV LP format is detected. It is determined that it has been detected. As described above, when DV LP format content is detected, the content is taken in by the IEEE1394 I / F 31, converted into DV SP format content by the DV codec 36, and recorded on the dubbing destination tape.

  If “HDV1080i” is selected as the capture mode, when content in a format other than the HDV1080i format is detected, it is determined that content other than the specified format has been detected, and “DVCAM” is selected. If a content of a format other than the DVCAM format is detected, it is determined that a content other than the designated format has been detected.

  When “DV SP” is selected as the capture mode, it is determined that content other than the specified format has been detected when content in a format other than the DV SP format is detected.

  In step S5, the main microcomputer 21 controls the sub-microcomputer 22 to determine the position of the tape on which no signal is recorded and the position of the tape on which content in a format other than the specified format is recorded on the external device. While fast-forwarding, the recording state by the tape drive unit 33 is stopped.

  Thus, no content is recorded on the dubbing destination tape while fast-forwarding is performed in the external device. If “ALL” is selected as the capture mode and it is detected that HDV720p format content is recorded on the dubbing source tape, no signal is recorded on the dubbing destination tape as described above. The

  When fast-forwarding is performed by an external device in step S5, for example, the IEEE1394 I / F 31 detects that content is recorded on the dubbing source tape, and the detected content is designated by the user. If it is determined that the content is in a certain format, the process returns to step S4, and the reproduction of the content by the external device and the recording by the recording control device 1 are resumed.

  As will be described later, when the rewinding is completed in step S6, the reproduction of the content by the external device and the recording by the recording control device 1 are resumed in step S4.

  For example, when the tape end of the dubbing source tape is detected by the IEEE1394 I / F 31 in the state of step S4 in which dubbing is being performed or in the state of step S5 in which the dubbing source tape is fast-forwarded, or the tape When the tape end of the dubbing destination tape attached to the attachment unit 11 is detected by the tape drive unit 33, the process proceeds to step S7.

  The dubbing interruption operation is performed by the user in the state of steps S2 to S4 described above, and the process proceeds to step S7 when it is accepted by the main microcomputer 21.

  In step S <b> 7, the main microcomputer 21 controls the sub-microcomputer 22 to stop reproduction by the external device and to stop recording by the tape drive unit 33. At this time, it is possible to replace the tape mounted on the external device, or replace the tape mounted on the tape mounting unit 11 of the recording control apparatus 1.

  When the dubbing restart operation is performed by the user and accepted by the main microcomputer 21, if the user does not select dubbing after rewinding the dubbing source tape and the dubbing destination tape, the process proceeds to step S4. The dubbing is resumed.

  On the other hand, when the dubbing restart operation is performed by the user in step S7 and accepted by the main microcomputer 21, the user selects to perform the dubbing after rewinding the replaced dubbing source and dubbing destination tapes. If so, the process proceeds to step S6.

  In step S6, the main microcomputer 21 controls the sub microcomputer 22 to rewind the exchanged tape of the dubbing source tape and the dubbing destination tape, and when the rewinding is completed, Proceeding to S4, dubbing is resumed.

  If the occurrence of an error is confirmed in the state of step S7 where dubbing is interrupted, the process proceeds to step S8, and the error is reconfirmed. When an operation for eliminating the error is performed by the user and accepted by the main microcomputer 21, the process returns to step S7.

  In the state of step S7, when the dubbing end operation is performed by the user and accepted by the main microcomputer 21, the main microcomputer 21 proceeds to step S9 and ends the dubbing process.
