Description

The present invention relates to a recording device for a disk recording medium such as a write-once recording disk or a rewritable recording disk with a limited number of rewrites, and more particularly, to a finalizing means and an information recording device using the same.

Conventionally, as a method of recording video information on a disk-shaped recording medium, there is a real-time video recording format as an application that performs video recording in real time and can easily perform editing processing after recording. This is a standard that allows TV broadcasts and the like to be recorded simultaneously with the broadcast, and that editing and erasing after recording can be easily performed.

On the other hand, the video format used in commercially available software that is assumed to be viewed on a commercially available DVD player is different from the video recording format because it is considered to be edited before recording. For this reason, there is a problem that a disc recorded in the video recording format cannot be viewed on a commercially available DVD player.

In view of this, a method has been proposed in which information is temporarily recorded in a simple format in real time, and the recording management data conforming to the standard video format is re-recorded by performing finalization processing at the end.

装置 Note that devices related to these are, for example, Patent Documents 1 and 2 and the like.

An actuator driver for driving an actuator (not shown), 36 is a video output terminal, 37 is a switch circuit, 38 is a camera unit, 39 is an output unit, 40 is a control unit, and 41 is a recording and reproducing unit.

Here, the operation of the camera section 38 will be described first. The image information is converted into an electric signal by the image sensor 6 via the lens unit 5 driven by the driver 11, and is converted into a video signal by the camera video signal processing circuit 7. On the other hand, the audio is converted into an audio signal by the audio input processing circuit 2 via the microphone 1.

Next, the operation of the output unit 39 will be described. The above signal is converted into a digital video / audio compression signal by a video / audio compression / expansion processing circuit 8. As a compression method, an MPEG method for handling moving images, a JPEG method for handling still images, and the like are implemented. The digital audio / video input terminal 12 can also handle external input information by switching. As an output means, an audio signal from the video / audio compression / expansion processing circuit 8 is output to an audio output terminal 4 via an audio output circuit 3. The video signal is displayed on the display means 10 via the video display / output processing circuit 9 and is output from the video output terminal 36 at the same time. Further, a digital video / audio signal is output from the digital output terminal 14 via the digital interface processing circuit 13. Here, the input signal and the output signal have been described via the video / audio compression / expansion processing circuit 8, but it goes without saying that these output signals do not necessarily need to be subjected to compression / expansion processing for both the audio signal and the video signal. No.

Next, the operation of the control unit 40 will be described. This device operates when the user operates the operation switch 18. The output of the operation switch 18 is input to the control microcomputer 16 of the entire apparatus. The control microcomputer 16 controls the lens unit 5 via the driver 11 to capture a desired image of the subject on the image sensor 6. Also, the video / audio compression / expansion processing circuit 8 controls to compress a moving image or a still image into a digital signal and temporarily store the digital signal in the D-RAM 15. These signals are sent to the signal / control processing circuit 24 of the disk type recording / reproducing apparatus via the interface circuit 19. As this interface circuit, for example, the ATAPI standard is adopted. In addition, the power supply state is monitored by monitoring the charging circuit 21, and the power supply processing of the camera unit is performed by controlling the switch circuit 37. The flash memory 17 is a memory for storing a program for operating the control microcomputer 16 and the like. The D-RAM 15 is a memory for temporarily storing processing data of the video / audio compression / expansion processing circuit 8 and processing data of the control microcomputer 16.

Finally, the operation of the recording / reproducing unit 41 will be described. The recording / reproducing unit 41 converts the moving image or still image information input from the interface circuit 19 into a recording format according to the disk medium in the signal / control processing circuit 24 and the D-RAM 25, and converts the information through the recording circuit 29 and the pickup 31. To record on the disk medium 32. The relative position between the disk medium 32 and the pickup 31 is determined by performing a reproduction operation on the pickup 31 in a time-division manner, detecting position information written in advance from the disk medium 32 via the reproduction circuit 30, and performing signal / control. Processed by the processing circuit 24 and the control microcomputer 28, the spindle motor 33 and the feed motor 34, which are actuators, and an actuator (not shown) for controlling focus and tracking in the pickup 31 are driven via an actuator driver 35. I do. Incidentally, the S-RAM 26 and the flash memory 27 temporarily store operation data of the control microcomputer 28 and programs.

The power supply circuit 23 supplies the power supplied from the external power supply input terminal 20 or the power supply of the battery 22 charged by the charging circuit 21 to the power supply circuit 23. ing.

Although the recording operation has been described above, almost the opposite operation is performed during reproduction. That is, information on the disk medium 32 is detected from the disk medium 32 via the pickup 31 and the reproduction circuit 30, and the signal / control processing circuit 24 and the control microcomputer 28 demodulate the recording format according to the disk medium, and the interface circuit 19 To the video / audio compression / expansion processing circuit 8 through which the compressed video signal and audio signal are decompressed, and the display means 10 via the video display / output processing circuit 9 and the audio output circuit 3 And output to the audio output terminal 4 and the video output terminal 36. Further, the information before expansion is output to the digital output terminal 14 via the digital interface processing circuit 13.

Furthermore, it has an external power supply input terminal 20 as a power supply unit, which enables external power supply. The battery 22 is charged by the charging circuit 21 using the power supplied from the external power input terminal 20. Thus, when the external power is supplied, the power is supplied to each block via the power circuit 23. When the external power is not connected, the power from the battery 22 is supplied to each block via the power circuit 23. Supply to block.

Here, as the disk medium 32 that handles video signals, for example, there are those as shown in Table 1. There is a DVD-ROM for reproduction only, a DVD-R as a write once type, and a DVD-RW and a DVD-RAM as rewritable media. For example, a video format (DVD Video format) and a video recording format (Video recording format) have been proposed as recording formats.

The video format uses video information that has been sufficiently edited in advance, such as movies, to realize its own functions such as multi-angle, parental playback, random shuffle playback, and special playback such as fast forward and rewind. Have strong information data to support.

ビ デ オ In addition, the video recording format considers an application that records a video signal in real time without any editing processing on the premise of this rewritable disc, and allows easy editing processing after recording. However, there is a problem that many signals recorded in the video recording format cannot be reproduced by many DVD players for reproducing a reproduction-only disc recorded in the video format.

The problem is that, especially when recording on a disc medium in a video camera, once a rewritable disc such as a DVD-RW or DVD-RAM is once recorded in a video recording format, an editing operation is performed, and the data is converted to the video format again. However, once a DVD-R disc is a write-once disc, which is recorded once in a video recording format, it cannot be rewritten and the disc cannot be re-recorded. Can not be played with.

Therefore, in the DVD-R disc, a method is adopted in which information is temporarily recorded in a simple format in real time, and the recording management data conforming to the standard video format is re-recorded by performing a finalizing process at the end. . Hereinafter, a DVD-R disc will be described as an example, but it goes without saying that the same processing can be applied to a DVD-RW or DVD-RAM disc.

FIG. 2 schematically shows the data structure of a DVD disk. In a DVD capable of recording and reproduction, the management areas are an R-information area (R-Information Area), a lead-in area (Lead-in Area), and a border-out / lead-out area (Border-out / Lead-out Area, The R-information area is composed of a power calibration area (Power Calibration Area) and a recording management area (Recording Management Area). By making the content of the out area equal to that of the read-only DVD-ROM, compatibility of reproduction is ensured.

Each time a process involving recording, such as recording new data in the data recording area or editing data recorded in the data recording area, is performed, predetermined recording management data is rewritten to these management areas. The recording state is managed by writing.

In FIG. 2, a groove (Groove) and a land (Land) are formed spirally around the clamping area CA on the disk, and a wobble (Wobble) for defining a physical address is provided in the groove and the land. ) And a land pre-pit.

Based on the wobble and land pre-pit information, the position of the pickup of the information recording / reproducing apparatus is controlled with respect to the wobble, so that information recording on the groove (data writing) and information reproduction from the groove (data reading) are performed. Is being done.

In the groove in which the data writing or data reading is performed, an R-information area (R-Information Area: RIA) and an information area (Information Area: RIA) extend from the radial inner side (clamping area CA side) to the radial outer side. IA).

The R-information area RIA includes a power calibration area (PCA) and a recording management area (RMA), and the information area IA includes a lead-in area (lead-in area: LIA). It comprises a data recordable area (DRA) and a lead-out area (LOA).

Next, the operation of the finalizing process will be described with reference to FIG.
In the figure, when the user operates the operation switch 18, the operation of the finalizing process starts. First, in step 102, the end of the main data already recorded in the data recording area DRA, that is, the address of the start end of the lead-out area LOA is detected. Further, a predetermined range of the lead-out area LOA in the standard format is recorded.

Next, in step 103, the recording management data DCW is recorded in the recording manager area RMA.

Next, in step 104, recording management data DCW is recorded in a predetermined area of the lead-in area LIA according to the standard format as predetermined data indicating that the finalization has been performed.

In this way, when the finalizing process is performed, if the loaded disc 32 has the simple format, the recording management data DCW is automatically recorded in accordance with the standard format. Compatibility is ensured.

However, in the finalizing process, when the already recorded area is small as described above, the lead-out area LOA is recorded to a predetermined range (for example, 70 mm in diameter). For this reason, depending on the conditions, it is conceivable that a dozen minutes of finalization processing time is required.

Here, an embodiment showing one feature of the present invention will be described with reference to FIG. In the present apparatus, when the finalizing process is started by operating the operation switch 18, as shown in FIG. 4, first, in step 112, the remaining amount of the battery 22 is determined. Here, when it is determined that there is a sufficient remaining amount for the finalizing process, the finalizing process is performed in step 114. However, when it is determined that the finalizing process is insufficient, the connection of the external power supply is performed in step 113. Is displayed on the display means 10 to inform the user. The remaining amount determination uses, for example, the voltage value of the normal battery terminal. That is, the remaining amount is determined using the fact that the voltage gradually decreases when the remaining amount of the battery is exhausted. Of course, other methods may be used.

Another embodiment will be described with reference to FIG. In the present apparatus, when the finalizing process is started by operating the operation switch 18, first, as shown in FIG. 5, in step 122, it is determined whether or not an external power supply is connected. This determination is made by detecting in the charging circuit 21 that the external power supply is connected to the external power supply input terminal 20 and providing the result to the control microcomputer 16. If there is an external power supply, the finalizing process is performed in step 124. If it is determined that the external power supply is not connected, the display unit 10 informs the user of the connection of the external power supply in step 123. indicate.

Another embodiment will be described with reference to FIG. In this apparatus, when the finalizing process is started by operating the operation switch 18, first, as shown in FIG. 6, it is determined in step 132 whether or not the battery and the external power supply are connected. This determination is made by detecting that the external power supply is connected to the battery 22 and the external power supply input terminal 20 by the charging circuit 21 and providing the result to the control microcomputer 16. If there is a battery and an external power supply, the finalizing process is performed in step 134. If it is determined that the battery and the external power supply are not connected, a display means is provided in step 133 to inform the user of the connection between the battery and the external power supply. This is indicated at 10.

In the present embodiment, the finalizing process is performed only when the power is supplied to the apparatus from both the battery and the external power source. That is, the finalizing process is not performed by using only one power source. Among them, there is an advantage that processing can be completed more safely even if one power supply is cut off for some reason.

Another embodiment will be described with reference to FIG. In the present apparatus, when the finalizing process is started by operating the operation switch 18, first, as shown in FIG. 7, it is determined in step 142 whether or not an external power supply is connected. If there is an external power supply, a finalizing process is performed in step 145. On the other hand, when there is no external power supply, the remaining amount of the battery 22 is determined in step 143. If it is determined that there is a remaining amount, a finalizing process is performed in step 145. If it is determined that there is no remaining amount, this is displayed on the display means 10 to inform the user of the connection of the external power supply in step 144.

In FIGS. 4, 6 and 7, etc., when the finalizing process is performed with the power supply of the battery 22, display examples of the finalizing process time and the remaining battery time are shown in FIGS. FIG. 8 shows the time required for the finalizing process and the remaining battery time so that the user can determine whether there is a sufficient remaining battery margin. This time is also displayed during the finalization process, and has the effect of displaying the remaining time until the process is completed. FIG. 9 shows another display example. An example is shown in which the remaining battery power is displayed as an image when the remaining battery time cannot be quantitatively represented by time.

Next, another feature of the present invention will be described with reference to FIG. In the finalization processing period, it is conceivable that another new operation is not accepted, especially in the sense of effectively using the remaining battery power. For example, a control signal from the control microcomputer 16 to the driver 11 for driving the lens unit 5 of the camera unit 38 is prohibited. Normally, the lens unit 5 is controlled via the control microcomputer 16 and the driver 11 by an operation such as tele / wide from the operation switch 18, but when the finalization process is started by the control microcomputer 16, this lens unit 5 Until the processing ends, for example, the operation of the camera unit such as the above-described tele / wide is prohibited. As a result, there is an advantage that the power consumption of the camera unit can be limited so as not to increase during the finalizing process.

In the same meaning, the power of the entire camera unit or a part thereof is not actively supplied during the finalization processing period. This can be realized by switching the switch circuit 37 by the control microcomputer 16.

Next, another embodiment of the present invention will be described with reference to FIGS. After starting the finalization process, it may be inevitably interrupted on the way for various reasons. For example, it is conceivable that the finalization process is started by mistake, that it is desired to immediately perform camera recording, or that the power supply is stopped. An example of such a process will be described with reference to FIG. After detecting the start end of the lead-out data recording in step 152, the data of the lead-out area is recorded in units of a predetermined amount in step 153. Then, every time recording is completed in units of a predetermined amount, in step 154, for example, the remaining battery level is detected and determined. If there is a predetermined remaining amount (a voltage value equal to or higher than a predetermined value), it is determined whether or not the lead-out area recorded in the next step 155 has reached a predetermined range. If it has not arrived, the process returns to step 153 again, and recording is resumed in units of a predetermined amount following the data of the already recorded lead-out area. If it is determined in step 155 that the recorded lead-out data has been recorded in the predetermined leader-out area, the recording management data of the disc is recorded in step 156, and the lead-in area is recorded in step 157.
Here, the disc management data and the lead-in area are predetermined areas, and the recording time is about several tens of seconds, which is much shorter than the lead-out area.

If it is determined in step 154 that there is no remaining battery (a voltage value equal to or less than a predetermined value), the process jumps to step 158 to interrupt the finalizing process and end.

In FIG. 10, although the determination of the remaining battery level is shown as step 154, this step may be the determination of the presence or absence of connection of the external power supply in FIG. The same effect can be obtained by applying the process of determining whether or not the user has input a command to interrupt the finalization process using the operation switch 18 to the apparatus in step 154.

Next, a method of re-finalizing the disc 32 suspended in such a state will be described. In the present apparatus, when the finalizing process is started by operating the operation switch 18, the start end of the lead-out data recording is detected in step 152 as shown in FIG. By this step 152, the last position of the already recorded lead-out data in the lead-out area is also detected for the disk 32 whose finalization processing has been interrupted in the middle, and subsequently, new lead-out data is newly added. By starting recording, the finalization process can be completed.

Next, an embodiment relating to a trigger for performing the finalizing process will be described with reference to FIG. 1 and FIGS. When the user executes the finalizing process, an instruction is given to the apparatus from the operation switch 18, and this may be caused, for example, by an operation to remove the disk 32 from the apparatus. That is, when the eject button (details are not shown) is operated to remove the disk 32 from the operation switch 18, a display as shown in FIG. 11 is displayed on the display means 10 by step 162 shown in FIG. Lets the user choose whether to perform the finalization process. At this time, the recorded capacity (or time, etc.) and the remaining capacity (or time, etc.) of the disk 32 are displayed to provide a user with information.

This display is particularly effective when the recording capacity of the disk 32 is low, and when the eject button (not shown) is operated by the present apparatus, the remaining capacity of the disk 32 is determined by step 172 shown in FIG. The remaining capacity is determined, and if the remaining capacity is equal to or more than the predetermined value, an ejecting operation is executed in step 174. If the remaining capacity is less than the predetermined value, in step 173, FIG. A configuration that prompts the user. Here, the remaining capacity of the disc 32 is determined by the control microcomputer 16 by collecting information on the remaining capacity of the recording capacity of the disc 32 from the control microcomputer 28 of the recording / reproducing unit 41 via the interface circuit 19 and the signal / control processing circuit 24. I do.

In addition, not only when the disk 32 is removed, but also when the recording pause (recording pause) is operated from the operation switch 18 at the time of camera recording with the present apparatus and the remaining capacity is less than a predetermined value, FIG. It is configured to prompt the execution of the finalizing process.

Further, even when the remaining capacity of the disk 32 is exhausted during recording, similarly to step 162 in FIG. 12, FIG. 11 is displayed to prompt the execution of the finalizing process.

Next, an embodiment regarding the shortening of the finalizing processing time will be described with reference to FIGS. 1, 14 and 15. FIG. At the time of normal camera recording, as shown in FIG. 14, a signal photographed by the camera unit 38 is compressed by the output unit 39 into a video / audio signal, and is taken as photographing information 64 in the buffer memory (D-RAM 15) in the control unit 40. Provided as buffer input 65. On the other hand, the recording / reproducing unit 41 loaded with the disk 32 normally drives the disk 32 at a sufficiently high recording transfer rate for recording real-time video captured by the camera unit 38. In particular, when a state occurs in which stable recording cannot be performed due to large vibrations or the like in a portable device, it is necessary to record the same information again at the same location or a different location on the disk 32. The buffer memory (D-RAM 25) is secured with a sufficiently large capacity, and the recording transfer rate on the disk 32 is set higher than the shooting information 64 rate as the upper input signal. In FIG. 14, about twice is shown as an example. That is, the buffer output 66 from the upper buffer memory (D-RAM 15) is intermittently read at a data rate about twice that of the upper buffer input 65, and this information is recorded on the disk 32. At this time, the ON / OFF state of the medium recording 67 is in the recording state only for about 1/2 period as shown in FIG.

On the other hand, recording on the disk 32 in the finalizing process is not necessary for real-time recording, unlike the upper-end camera recording. Further, it is preferable that the processing time be completed in a short time from the viewpoint of ease of use and power consumption. Therefore, as shown in FIG. 15, the lead-out recording data 68 generated by the signal / control processing circuit 24 or the like is continuously recorded (on state) on the disk 32 as shown in the medium recording 69, so that the data can be compared at the time of camera recording. The average recording transfer rate is increased to shorten the finalization processing time. Here, the recording data in the lead-out area has been described, but the same applies to other recording management data and data in the lead-in area.

Also, in this description, the maximum recording transfer rate is described as being the same, but of course, the rotation speed of the disk 32 during the finalizing process is increased to further increase the maximum transfer rate, thereby shortening the processing time and reducing power consumption. May be.
