Description

  The present invention relates to a recording device, a data output device, a heterogeneous data recording method, a heterogeneous data output method, and a program, and in particular, a recording device that records data of different formats on the same recording medium, and data of different formats to the recording device. Data output device for transmission, heterogeneous data recording method applied to the recording device, heterogeneous data output method applied to the data output device, and to cause a computer to execute the heterogeneous data recording method and the heterogeneous data output method Regarding the program.

  Conventionally, a digital VTR (Video Tape Recorder) that records and reproduces an image signal on a magnetic tape as a digital signal is known. In recent years, digital VTRs have been introduced in which high-definition (HD) images are captured instead of conventional standard resolution (SD) images, encoded by the MPEG method, and recorded on a magnetic tape (for example, patent documents). 1).

  The DV system has been proposed as a consumer digital VTR standard for recording SD signals, and the HDV system has been proposed as a consumer digital VTR standard for recording HD signals. In the HDV system, an MPEG encoded image signal is recorded on the same magnetic tape as in the DV system.

The above-described digital VTR includes a digital I / F (interface) for outputting image data in an encoded state to the outside. Therefore, it is possible to perform dubbing by connecting two digital VTRs with a digital I / F. In this case, if the reproducing and transmitting side is an HDV digital VTR and the receiving and recording side is a DV digital VTR, the signal formats handled by the two are different, so the receiving and recording side records directly. I can't. Therefore, the HDV digital VTR on the playback transmission side converts the MPEG-encoded HDV data to DV data and transmits it, thereby enabling dubbing.
JP 2001-275077 A

  By the way, as described above, since the HDV digital VTR and the DV digital VTR use the same type of magnetic tape, the SD signal is obtained by the DV method and the HD signal is obtained by the HDV method. A digital VTR has been introduced which can record at the front and rear positions of one magnetic tape.

  When reproducing the image data recorded on such a digital VTR, the image signal is at the boundary between the portion where the DV SD signal is recorded on the magnetic tape and the portion where the HDV HD signal is recorded. It is necessary to switch the playback method.

  Therefore, image data reproduced from a magnetic tape in which HDV image data and DV image data are mixedly recorded is dubbed via the digital I / F in the two conventional digital VTRs. In this case, normal dubbing may not be possible. That is, in the dubbing source digital VTR, the playback method of the image signal must be switched at the boundary of the magnetic tape. However, as long as the dubbing is not stopped, a normal image is displayed in the dubbing destination digital VTR. There is a problem in that no signal is transmitted and meaningless data is recorded in the dubbing destination digital VTR.

Further, when performing such dubbing, the operator needs to perform an operation of switching the image signal reproduction method at the boundary of the magnetic tape, and it is desirable that dubbing is possible without performing such an operation. It was.

[First Embodiment]
FIG. 1 is a block diagram showing a main configuration of a recording apparatus according to the first embodiment of the present invention. The recording apparatus includes a control device including a CPU, a RAM, a ROM, and the like. The control device executes a predetermined control program, thereby realizing the functions of the respective units shown in FIG.

  In FIG. 1, reference numeral 11 denotes a digital interface (I / F) unit using a communication method conforming to the IEEE 1394 standard, which receives DV format data or MPEG format data transmitted from a data output device (reproducing device) (not shown). Do.

  The IEEE 1394 standard supports two transfer modes: asynchronous (asynchronous) transfer and isochronous (isochronous) transfer. Asynchronous transfer is a transfer of a control command or the like for controlling a connected device. In isochronous transfer, data reproduced by a data output device is transferred using an isochronous packet. The isochronous packet includes an isochronous packet header, a CIP (Common Isochronous Packets) header, and a data block. The format of the data to be transferred is identified by the FMT area of the CIP header. For example, if “000000” is described in the FMT area, it is defined as the DV format, and if “100000” is described, it is defined as the MPEG format. Yes.

  The data in the FMT area is input to the format detection unit 12, and MPEG / DV format detection is performed.

  Reference numeral 13 denotes a format selection unit for the operator to select and specify the format of data to be dubbed and recorded. A recording unit 14 records data output from the digital interface unit 11 on a recording medium (not shown) according to a format selected by the operator and input to the format selection unit 13.

  FIG. 2 is a flowchart showing a procedure of recording processing executed in the recording unit 14.

  In step S21, the recording unit 14 first determines whether the format (recording mode) selected by the operator and input to the format selection unit 13 is the MPEG mode or the DV mode. As a result, if it is determined that the MPEG mode is selected and input, the process proceeds to step S28, and if it is determined that the DV mode is selected and input, the process proceeds to step S22.

  In step S22, the digital interface unit 11 is set to a state in which DV format data can be received. In step S23, it is determined whether data is input to the digital interface unit 11. If data is input, the process proceeds to step S24, and if data is not input, the process proceeds to step S27.

  In step S24, it is determined whether or not the DV format is detected by the format detector 12. As a result, when the DV format is detected, the process proceeds to step S25, and when the DV format is not detected, the process proceeds to step S26.

  In step S25, the DV format data input from the digital interface unit 11 is recorded on the recording medium. On the other hand, in step S26, the process waits without recording data. After execution of step S25 or step S26, the process returns to step S23, and the processes of steps S23 to S26 are repeated until no data is input to the digital interface unit 11.

  When no data is input to the digital interface unit 11, the process proceeds to step S27, and the recording process in the recording unit 14 is terminated.

  In step S28, the digital interface unit 11 is set to a state in which MPEG format data can be received. In step S29, it is determined whether data is input to the digital interface unit 11. If data has been input, the process proceeds to step S210, and if data has not been input, the process proceeds to step S27.

  In step S210, it is determined whether or not the MPEG format is detected by the format detector 12. As a result, if the MPEG format is detected, the process proceeds to step S211. If the MPEG format is not detected, the process proceeds to step S212.

  In step S211, the MPEG format data input from the digital interface unit 11 is recorded on a recording medium. On the other hand, in step S212, the process waits without recording data. After execution of step S211 or step S212, the process returns to step S29, and the processing of steps S29 to S212 is repeated until no data is input to the digital interface unit 11.

  When no data is input to the digital interface unit 11, the process proceeds to step S27, and the recording process in the recording unit 14 is terminated.

  As described above, in the first embodiment, if the format selected by the operator and input to the format selection unit 13 matches the format of the input data detected by the format detection unit 12, the recording medium is recorded. Recording is performed, and if there is a discrepancy, recording is not performed. This makes it possible to ensure good workability when dubbing a magnetic tape recorded with a mixture of MPEG format image data and DV format image data.

  In step S42, it is determined whether or not the format format in which the digital interface unit 31 is in a receivable state matches the format format detected by the format detection unit 32. If the format is matched, the process proceeds to step S49, and if not, the process proceeds to step S43.

  In step S49, the control unit 34 outputs a reproduction request command to the digital interface unit 31, and in the next step S410, the control unit 34 outputs a recording request to the recording unit 33 to execute a dubbing operation.

  On the other hand, in step S43, the control unit 34 outputs a reproduction standby request command to the digital interface unit 31, and in the next step S44, the control unit 34 outputs a recording standby request to the recording unit 33 to interrupt the dubbing operation. .

  Next, in step S45, it is determined whether the format detected by the format detector 32 is DV format or MPEG format. If it is DV format, the process proceeds to step S46, and if it is MPEG format, step S47 is performed. Proceed to

  In step S46, the digital interface unit 31 is set in a state where DV format data can be received, and in step S47, the digital interface unit 31 is set in a state where MPEG format data can be received.

  In the next step S48, it is determined whether or not the format format set by the digital interface unit 31 matches the format format detected by the format detection unit 32. If they do not match, wait until they match. If the format is the same, the process proceeds to step S49, where the control unit 34 outputs a reproduction request command to the digital interface unit 31, and in the next step S410, the control unit 34 outputs a recording request to the recording unit 33 to perform dubbing. Perform the action.

  The processes in steps S41 to S410 are repeated until it is determined in step S41 that no data is input to the digital interface unit 31. If it is determined in step S41 that no data has been input, the process proceeds to step S411.

  In step S411, the control unit 34 outputs a reproduction stop request command to the digital interface unit 31, and in the next step S412, the control unit 34 outputs a recording stop request to the recording unit 33 and ends the dubbing process.

  As described above, in the second embodiment, when the format format of the data that can be received by the digital interface unit 31 does not match the format format detected by the format detection unit 32, the digital interface unit 31 is changed to the format detection unit. In the receiving state, the data of the same format as the format detected at 32 is received. This makes it possible to ensure good workability when dubbing a magnetic tape recorded with a mixture of MPEG format image data and DV format image data.

As a result, if it is the MPEG mode, the process proceeds to step S108, if it is the DV mode, the process proceeds to step S102, and if it is the DV & MPEG mode, the process proceeds to step S1013.

  In step S102, the digital interface unit 31 is set to a state in which DV format data can be received. In step S103, it is determined whether or not data is input to the digital interface unit 31. As a result, if data is input, the process proceeds to step S104, and if data is not input, the process proceeds to step S107.

  In step S104, the format detection unit 32 determines whether a DV format has been detected. As a result, when the DV format is detected, the process proceeds to step S105, and when the DV format is not detected, the process proceeds to step S106.

  In step S108, the digital interface unit 31 is set to a state in which MPEG format data can be received. In step S109, it is determined whether or not data is input to the digital interface unit 31. As a result, if data is input, the process proceeds to step S1010, and if data is not input, the process proceeds to step S107.

  In step S1010, the format detection unit 32 determines whether an MPEG format has been detected. As a result, if the MPEG format is detected, the process proceeds to step S1011. If the MPEG format is not detected, the process proceeds to step S1012.

On the other hand, in step S1012, a recording standby request is output to the recording unit 33, and dubbing is interrupted. After execution of step S1011 or step S1012, the process returns to step S109, and the processing of steps S109 to S1012 is repeated until no data is input to the digital interface unit 31.

  When no data is input to the digital interface unit 31, the process proceeds to step S107, a recording end request is output to the recording unit 33, and the diving process is ended.

  Next, the processing after step S1013 in FIG. 7 will be described.

  When the DV & MPEG mode in which both the DV format data and the MPEG format data can be input is selected by the operator and input to the format selection unit 95, the process proceeds from step S101 to step S1013. In step S <b> 1013, the control unit 94 determines whether data is input to the digital interface unit 31. If data is input, the process proceeds to step S1014.

  In step S <b> 1014, it is determined whether the format format in which the digital interface unit 31 is in a receivable state matches the format format detected by the format detection unit 32. If the format formats match, the process proceeds to step S1021, and if the format formats do not match, the process proceeds to step S1015.

  In step S1021, the control unit 94 outputs a reproduction request command to the digital interface unit 31, and in the next step S1022, the control unit 94 outputs a recording request to the recording unit 33 to execute a dubbing operation.

  On the other hand, in step S1015, the control unit 94 outputs a playback standby request command to the digital interface unit 31, and in the next step S1016, the control unit 94 outputs a recording standby request to the recording unit 33 and interrupts the dubbing operation. .

In such a case, as in the second embodiment, when the format format of the data that can be received by the digital interface unit 31 does not match the format format detected by the format detection unit 32, the digital interface unit 31 detects the format. The reception state is set to receive data having the same format as the format detected by the unit 32. This makes it possible to ensure good workability when dubbing a magnetic tape recorded with a mixture of MPEG format image data and DV format image data.

The format of the data to be reproduced is identified by information described in the APT area of the ITI sector defined by the “DV standard” and “HDV standard”. For example, when “000” is described in the APT area, it is identified as DV format, and when “100,000” is described as MPEG format. The data described in this APT area is input to the format detection unit 52, and MPEG / DV format detection is performed.

  Reference numeral 53 denotes a format selection unit for the operator to select and input the format of data that the operator wants to record. Reference numeral 54 denotes a digital interface (I / F) unit using a communication system conforming to the IEEE 1394 standard, and transmits data to a recording apparatus (recorder) (not shown). The digital interface unit 54 supports two transfer modes: isochronous transfer for transferring data reproduced by the reproduction unit 51 and asynchronous transfer for transferring a control command for controlling a connected device. .

  A control unit 55 controls the reproduction operation of the reproduction unit 51 and generates a control command for controlling a recording apparatus (not shown) connected via the digital interface unit 54.

  Next, the dubbing process performed by the control unit 55 will be described with reference to FIGS. 9 and 10.

  9 and 10 are flowcharts showing the procedure of the dubbing process performed by the control unit 55 shown in FIG.

  First, in step S61, the control unit 55 determines whether the mode selected and input by the operator to the format selection unit 53 is the HDV mode (a mode in which MPEG format data can be transmitted), or the DV mode (DV format data). Is in a mode capable of transmitting). As a result, if it is the HDV mode, the process proceeds to step S611, and if it is the DV mode, the process proceeds to step S62.

  In step S62, the digital interface unit 54 is set to a state in which DV format data can be transmitted (set to the DV mode). Next, in step S63, the control unit 55 determines whether or not reproduction data is output from the reproduction unit 51. If the reproduction data is output, the process proceeds to step S64, and if the reproduction data is not output, the process proceeds to step S69.

  In step S64, the control unit 55 determines whether or not the format detected by the format detection unit 52 is the DV format. If the format is the DV format (DV data is detected), the process proceeds to step S65. If it is not in the format (DV data is not detected), the process proceeds to step S67.

  In step S65, the control unit 55 outputs a reproduction request to the reproduction unit 51, and in the next step S66, outputs a recording request command to the digital interface unit 54 and ends the dubbing process.

  In step S67, the control unit 55 outputs a recording standby request command to the digital interface unit 54, and in the next step S68, a search request for searching for DV format data is output to the reproduction unit 51, and dubbing is interrupted.

  The processes in steps S63 to S68 are repeated until it is determined in step S63 that reproduced data is not output. If it is determined in step S63 that the reproduction data has not been output, the process proceeds to step S69, where the control unit 55 outputs a reproduction end request to the reproduction unit 51, and in the next step S610, recording ends to the digital interface unit 54. The request command is output and the dubbing process is terminated.

  In step S611, the control unit 55 sets the digital interface unit 54 in a state in which MPEG format data can be transmitted (set to the HDV mode). Next, in step S612, the control unit 55 determines whether or not reproduction data is output from the reproduction unit 51. As a result, if the reproduction data is output, the process proceeds to step S613, and if the reproduction data is not output, the process proceeds to step S69.

  In step S613, the control unit 55 determines whether or not the format detected by the format detection unit 52 is the HDV format. If the format is the HDV format (HDV data is detected), the process proceeds to step S614. If it is not a format (HDV data is not detected), the process proceeds to step S616.

  In step S614, the control unit 55 outputs a reproduction request to the reproduction unit 51, and in the next step S615, outputs a recording request command to the digital interface unit 54 to execute dubbing.

  On the other hand, in step S616, the control unit 55 outputs a recording standby request to the digital interface unit 54. In step S617, the control unit 55 outputs a search request for searching for MPEG format data to the reproduction unit 51, and interrupts dubbing.

  The processes in steps S612 to S617 are repeated until it is determined in step S612 that no reproduction data is output. If it is determined in step S612 that no reproduction data has been output, the process proceeds to step S69, where the control unit 55 outputs a reproduction end request to the reproduction unit 51, and in the next step S610, recording ends to the digital interface unit 54. The request is output and the dubbing process is terminated.

  Thus, in the fourth embodiment, if the format selected by the operator and input to the format selection unit 53 matches the format of the reproduction data detected by the format detection unit 52, the reproduction is performed. The reproduction by the unit 51 and the transmission by the digital interface unit 54 are executed. If they do not match, playback by the playback unit 51 and transmission by the digital interface unit 54 are not executed. This makes it possible to ensure good workability when dubbing a magnetic tape recorded with a mixture of MPEG format image data and DV format image data.

[Fifth Embodiment]
FIG. 11 is a block diagram showing a main configuration of a data output apparatus according to the fifth embodiment of the present invention. Since the configuration of the data output apparatus according to the fifth embodiment is basically the same as the configuration of the data output apparatus according to the fourth embodiment shown in FIG. 8, the same reference numerals are used for the same parts. A description thereof will be omitted.

  Also in the fifth embodiment, the digital interface unit 54 sends an isochronous transfer for transferring reproduction data from the reproduction unit 51 and a control command for controlling the connection destination device (recording device) to the connection destination device. Two transfer modes are supported: asynchronous transfer and transfer.

  By the way, in the asynchronous transfer, a control command for inquiring the state of the connection destination device is prepared. For example, the status of the connection destination device can be inquired by using the “AV / C Input Plug Signal Format” command. As a result, the format information is described in the FMT area of the CIP header and transmitted from the connection destination device. .

  Therefore, the format setting detection unit 74 detects the format information described in the FMT area of the CIP header transmitted from the recording device that is the connection destination device.

  The control unit 75 controls the reproduction operation of the reproduction unit 51 and generates a control command for controlling a recording device (not shown) connected to the digital interface unit 54.

  Next, a dubbing process performed by the control unit 75 will be described with reference to FIG.

  FIG. 12 is a flowchart showing the procedure of the dubbing process performed by the control unit 75 of FIG.

  First, in step S81, the control unit 75 determines whether or not reproduction data is output from the reproduction unit 51. If the reproduction data is output, the process proceeds to step S82, and if not, the process proceeds to step S88.

  In step S <b> 82, the control unit 75 determines whether or not the format type detected by the format setting detection unit 74 matches the format type detected by the format detection unit 52. If the format is matched, the process proceeds to step S86, and if not, the process proceeds to step S83.

  In step S86, the control unit 75 outputs a reproduction request to the reproduction unit 51, and in the next step S87, outputs a recording request command to the digital interface unit 54 to execute a dubbing operation.

  In step S83, the control unit 75 outputs a reproduction standby request to the reproduction unit 51, and in the next step S84, outputs a recording standby request command to the digital interface unit 54 to interrupt the dubbing operation. At this time, the recording apparatus side receives a recording standby request command, detects a format mismatch, and executes switching of the format setting.

  In step S85, the control unit 75 waits until the switching of the format setting in the recording apparatus is completed and the format format detected by the format setting detection unit 74 matches the format format detected by the format detection unit 52. If it is determined in step S85 that the format formats match, the process proceeds to step S86.

  In step S86, the control unit 75 outputs a reproduction request to the reproduction unit 51. In the next step S87, a recording request command is output to the digital interface unit 54, and the dubbing operation is resumed.

  The processes in steps S81 to S87 are repeated until it is determined in step S81 that reproduced data is not output. If it is determined in step S81 that the reproduction data is not output, the process proceeds to step S88, where the control unit 75 outputs a reproduction stop request to the reproduction unit 51, and in the next step S89, a recording stop request is sent to the digital interface unit 54. A command is output and the dubbing process is terminated.

  As described above, in the fifth embodiment, when the format format on the recording apparatus side detected by the format setting detection unit 74 and the format format of the reproduction data detected by the format detection unit 52 do not match. Then, a recording standby request command is transmitted to the recording apparatus side. As a result, the format format is changed on the recording device side, and after this change, data reproduction by the reproduction unit 51 and transmission of reproduction data by the digital interface unit 54 are executed. This makes it possible to ensure good workability when dubbing a magnetic tape recorded with a mixture of MPEG format image data and DV format image data.

[Sixth Embodiment]
FIG. 13 is a block diagram showing a main configuration of a data output apparatus according to the sixth embodiment of the present invention. Since the configuration of the data output apparatus according to the sixth embodiment is basically the same as that of the data output apparatus according to the fifth embodiment shown in FIG. 11, the same reference numerals are used for the same parts. A description thereof will be omitted.

  In the sixth embodiment, a format selection unit 116 is provided for the operator to select and input the format of data that the operator desires to record. Further, a control unit 115 that performs control different from the control unit 75 in the fifth embodiment is provided.

  14 to 16 are flowcharts showing the procedure of the dubbing process executed by the control unit 115.

  The processing in steps S121 to S1217 shown in FIGS. 14 and 15 is the same as the processing in steps S61 to S617 of the dubbing processing in the fourth embodiment shown in FIGS. Therefore, the description is omitted here.

  In step S121 shown in FIG. 14, the control unit 115 determines whether the format selected by the operator and input to the format selection unit 116 is the MPEG mode (HDV mode), the DV mode, or DV & MPEG. Determine whether the mode. As a result, if it is determined that the DV & MPEG mode is selected and input, the process proceeds to step S1218 in FIG.

  In step S1218, the control unit 115 determines whether or not reproduction data is output from the reproduction unit 51. If the reproduction data is output, the process proceeds to step S1219. If the reproduction data is not output, the process proceeds to step S1228.

  In step S1219, it is determined whether or not the format type detected by the format setting detection unit 74 matches the format type detected by the format detection unit 52. If the format formats match, the process proceeds to step S1226, and if they do not match, the process proceeds to step S1220.

  In step S1226, the control unit 115 outputs a reproduction request to the reproduction unit 51. In the next step S1227, a recording request command is output to the digital interface unit 54 to execute a dubbing operation.

  On the other hand, in step S1220, the control unit 115 outputs a reproduction standby request to the reproduction unit 51, and in the next step S1221, outputs a recording standby request command to the digital interface unit 54 to interrupt the dubbing operation.

  Next, in step S1022, it is determined whether the format detected by the format detector 52 is the DV format or the MPEG format. If it is the DV format, the process proceeds to step S1223, and if it is the MPEG format, the process proceeds to step S1224.

  In step S1223, the digital interface unit 54 is set in a state in which DV format data can be received. In step S1224, the digital interface unit 54 is set in a state in which MPEG format data can be received, and the process proceeds to step S1225.

  In step S1225, the process waits until the setting in the digital interface unit 54 is completed and the format format set in the digital interface unit 54 matches the format format detected in the format detection unit 52. If the format formats match, the process proceeds to step S1226.

  In step S1226, the control unit 115 outputs a reproduction request to the reproduction unit 51. In the next step S1227, a recording request command is output to the digital interface unit 54, and the dubbing operation is resumed.

  The processes in steps S1218 to S1227 are repeated until it is determined in step S1218 that reproduced data is not output. If it is determined in step S1218 that the reproduction data has not been output, the process proceeds to step S1228, in which the control unit 115 outputs a reproduction stop request to the reproduction unit 51, and in the next step S1229, a recording stop request is sent to the digital interface unit 54. A command is output and the dubbing process is terminated.

  As described above, in the sixth embodiment, the format format of the reproduction data detected by the format detection unit 52 and the setting format format of the external device (recording device) detected by the format setting detection unit 74 are the same. If not, the format set in the digital interface unit 54 is changed to match the format format of the reproduction data. This makes it possible to ensure good workability when dubbing a magnetic tape recorded with a mixture of MPEG format image data and DV format image data.

Data comprising reproducing means for reproducing a plurality of data recorded in a recording medium in different formats, and transmitting means capable of transmitting a plurality of data each having a different format reproduced by the reproducing means to an external storage device In a program for causing a computer to execute a heterogeneous data output method applied to an output device,
A reproduction data format detection step for detecting a format of data reproduced by the reproduction means;
An external setting format detection step for detecting a format of data to be recorded by the external recording device;
If the format detected by the reproduction data format detection step does not match the format detected by the external setting format detection step, a recording standby command is sent to the external recording device via the transmission means. A command sending step for sending
After the recording standby command is transmitted, the reproduction by the reproduction unit and the transmission unit are performed in accordance with a match between the format detected by the reproduction data format detection step and the format detected by the external setting format detection step. And a control step for executing transmission. Data output comprising a reproducing means for reproducing a plurality of data recorded on a recording medium in different formats and a transmitting means capable of transmitting a plurality of data each having a different format reproduced by the reproducing means to an external device In a program for causing a computer to execute a heterogeneous data output method applied to an apparatus,
A reproduction data format detection step for detecting a format of data reproduced by the reproduction means;
An external setting format detection step for detecting a format set in the external device;
When the format detected in the reproduction data format detection step does not match the format detected in the external setting format detection step, the format of data to be transmitted by the transmission means is determined as the reproduction data format detection step. And a setting step for setting to a format that matches the format detected in (1).
