Abstract

When reading video data of a large size in a storage device and writing it to a recording medium with a small remaining capacity, if the size of the original data is larger than the remaining capacity of the recording medium to which the data is written, the video will be included in the remaining capacity of the recording medium. The data size is automatically divided to enable writing.
When copying large-size data of the copy source of the HDD 16 to the DVD 18 compared to the remaining capacity of the DVD 18, the remaining capacity is detected from the DVD 18 on which the remaining capacity is recorded, and the copy source data is stored on the DVD 18. The data is divided into sizes that fit in the remaining capacity and copied to the DVD 18. At this time, every time the copy source data of the HDD 16 is divided and copied, the division information indicating that the copy has been completed is created as a correspondence table in association with the copy source data. Then, at the time of the next copy, when the data portion following the previous divided copy is copied to another recording medium, the copy source data is divided and copied from the position of the previous division information.

  Embodiments of the invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a recording / reproducing apparatus according to Embodiment 1 of the present invention.
In FIG. 1, the apparatus main body 10 of the recording / reproducing apparatus includes a CPU 11 that controls each part in the main body, a ROM 12 that stores a program for controlling the inside of the main body and peripheral devices, and data necessary for the calculation and various processes of the CPU 11. , A bus line 14 connected to the CPU 11 for exchanging data with the interface of each unit, a hard disk interface (hereinafter referred to as HDD I / F) 15 connected to the CPU 11 via the bus line 14, An HDD 16 connected to the HDD I / F 15 for storing video and audio data, management data, and the like, and a DVD interface (hereinafter referred to as a DVD I / F) 17 connected to the bus line 14 to control writing and reading to the DVD 18. And connected to the bus line 14 for writing / reading drive control to the SD card 20 An SD interface (hereinafter referred to as SD I / F) 19, a display interface (hereinafter referred to as display I / F) 21 as display control means connected to the bus line 14 and performing display drive control of the display unit, and a display I / F Display unit 22 connected to F21 for displaying the current state of the apparatus main body and external recording medium (DVD, SD card, etc.) and operation information for the user, and light reception for receiving an infrared remote control signal from a remote controller (not shown). And a remote control interface (hereinafter referred to as a remote control I / F) 23 that processes a remote control signal from the light receiving unit 24 and notifies the CPU 11 via the bus line 14.

  The DVD I / F 17 of the apparatus body 10 drives the DVD 18 under the control of the CPU 11 with the DVD 18 placed on a disk tray (not shown). Similarly, the SD I / F 19 of the apparatus main body 10 drives the SD card 20 under the control of the CPU 11 with the SD card 20 mounted in a card socket (not shown). That is, the DVD 18 and the SD card 20 can be attached to and detached from the apparatus main body 10, respectively.

  Now, in the recording / reproducing apparatus as shown in FIG. 1, large-size data recorded in advance in the HDD 16 (for example, continuous data for 10 hours in the SP mode) is copied to the DVD 18 or the SD card 20, and this is stored in the apparatus main body. As an example, consider a usage mode in which the player is removed from the mounting portion 10 and attached to a portable DVD player as shown in FIG. 2A or a micro personal computer (referred to as a pocket PC) as shown in FIG. .

  In such a usage example, the storable capacity of the DVD 18 and the SD card 20 is smaller than the size of data recorded in the HDD 16 built in the apparatus main body 10 of the recording / reproducing apparatus. The continuous data for 10 hours cannot be copied to the DVD 18 or the SD card 20. Therefore, it is possible to copy 10 hours of continuous data into, for example, 2 hours so as to be in a DVD, but conventionally, as in Patent Document 1, 10 hours of continuous data is possible. In order to copy data to a plurality of DVDs, the user had to perform an editing operation to divide the HDD copy source data by two hours in advance.

  Thus, in the first embodiment of the present invention, the above-described large-size copy source data in the HDD is solved by automatically dividing it into a size that fits in the remaining capacity of the copy destination DVD or SD card.

  3 and 4 show flowcharts for explaining the operation of the CPU 11 of the apparatus main body 10. A case will be described in which a DVD 18 is mounted on the apparatus main body (hereinafter, HDD side) 10 and copying is performed from the HDD side to the DVD side. Here, the DVD 18 is selected as the copy destination recording medium, but the same applies to the copy operation of the SD card 20.

  In FIG. 3, when the copy button of the remote controller (not shown) is operated with the DVD side selected as the copy destination, the CPU 11 first reads the remaining capacity information held by the DVD 18 (step S1), and the copy source HDD. The data amount on the side and the remaining capacity on the copy destination DVD side are compared (step S2). If the continuous data amount on the HDD side is smaller than the remaining capacity on the DVD side, all the continuous data on the HDD side is copied to the DVD 18 (step S5).

  If the amount of data on the HDD side is larger than the remaining capacity on the DVD side, the original data on the HDD side is divided into sizes that fit in the remaining capacity of the DVD 18, read out, and written on the DVD 18. That is, division copying is performed (step S3). Then, when the CPU 11 reads the divided content from the copy source data of the HDD 16, it writes a flag as division information (information indicating the division position) in the copy source data in the HDD 16 (step S4). That is, by writing a flag for the first time at the division position in the copy source data of the HDD 16, a correspondence table is created in which the division information indicating that the copy has been completed is associated with the copy source data.

  Thereafter, the display unit 22 displays whether the user continues to copy the previous continuation, does not copy the continuation (that is, whether to copy the next continuation at a later date, etc.), or copies from the beginning of the copy source data. In accordance with the operation screen shown in FIG. 6, for example, the selection is made by the cursor movement and determination (OK) operation by the remote controller (step S6). If "copy continuation" is selected, it is determined in step S7 whether or not all the original data on the HDD side has been copied. Since this is the first time, step S7 proceeds to “NO”, and an instruction to replace and mount another DVD is displayed on the display unit 22. Therefore, when another DVD is loaded (step S8), the flow returns to step S1 and the flow of steps S2 to S8 is repeated again, and divided copies to a plurality of DVDs 18 are carried out. The first and subsequent division flags are written in the copy source data, and a correspondence table is created.

  If it is determined in step S7 that all copy source data on the HDD side has been divided and copied, the process ends. If “copy from the beginning” is selected in step S6, the detailed operation is omitted, but the copy operation from the beginning of the copy source data on the HDD side is not referred to without referring to the flag that is the division information on the correspondence table. (Step S9).

  On the other hand, in step S6 of FIG. 3, after performing the first and subsequent divided copies (however, all of the copy source data has not been divided), select “Do not copy” and finish. In the case of performing a divided copy from the next time following the previous time at a later date or the like, the process proceeds according to the flowchart of FIG.

  When the power of the recording / reproducing apparatus main body 10 is turned on at a later date, the CPU 11 first detects the incomplete copy of the remaining data following the previous divided copy with respect to the content desired to be copied by referring to the correspondence table of the HDD 16 ( If it is known that all the contents of the copy source data have not been copied), the process proceeds to the flowchart of FIG.

  In FIG. 4, when a copy button of a remote controller (not shown) is operated in a state where a new DVD 18 is mounted on the apparatus main body 10 and the DVD 18 is selected as a copy destination, the CPU 11 first displays the remaining capacity information held by the DVD 18. Reading (step S11), the data amount on the copy source HDD side is compared with the remaining capacity on the copy destination DVD side (step S12). If the data amount on the HDD side is smaller than the remaining capacity on the DVD side, all the data on the HDD side is copied to the DVD 18 (step S16).

  If the amount of data on the HDD side is larger than the remaining capacity on the DVD side, the user copies the continuation from the previous time, does not copy (that is, cancels the current copy), or starts the copy source data Is selected by cursor movement and determination (OK) operations using the remote controller in accordance with, for example, the operation screen shown in FIG. 6 displayed on the display unit 22 (step S13).

  When “copy continuation” is selected in step S 13, the copy source data on the HDD side is divided into sizes that fit in the remaining capacity of the DVD 18, read out, and written onto the DVD 18. That is, division copying is performed (step S14). When the CPU 11 reads the divided content from the copy source data of the HDD 16, the CPU 11 writes a flag as division information in the copy source data in the HDD 16 (step S15). That is, the correspondence table is created by adding a flag to the next division position of the content of the copy source data in the HDD 16 for the previous time.

  After that, the user copies either the continuation from the previous time, does not copy (that is, cancels without performing the next divided copy), or copies from the beginning of the copy source data, Selection is performed by cursor movement and determination (OK) operations using the remote controller according to the operation screen shown in FIG. 6 displayed on the display unit 22, for example (step S18). If “copy continuation” is selected, it is determined whether or not all the copy source data on the HDD side has been copied (step S19). If all the copy source data on the HDD side has been copied, the process ends. If all the copy source data has not been copied, the process proceeds to “NO”, and an instruction to replace and mount another DVD is displayed on the display unit 22. Is done. Therefore, when another DVD is loaded (step S20), the process returns to step S11 and the flow of steps S12 to S20 is repeated again, and divided copies are made on the plurality of DVDs 18 and divided into copy source data in the HDD 16 as well. Each time, a plurality of division flags are written and created as a correspondence table.

  If it is determined in step S19 that all the copy source data on the HDD side is divided and copied, the process ends. If “copy from the beginning” is selected in steps S13 and S18, the detailed operation is omitted, but the flag as the division information on the correspondence table is not referred to, and the copy source data on the HDD side is started from the beginning. The copying operation can be performed (steps S17 and S21).

  In the above-described embodiments shown in FIGS. 3 and 4, the copy destination recording medium is described as only the DVD for easy understanding. However, as the flow of the copy operation, first the copy destination recording medium is selected. Steps can also be added. That is, at the start of the copy operation of FIGS. 3 and 4, first, the CPU 11 selects the copy destination recording medium (DVD or SD card) and then the CPU 11 selects the copy destination recording medium (for example, the SD card). ) Is read and compared with the size of the content of the copy source on the HDD side, and if the remaining capacity of the SD card is smaller in the same manner as in FIG. 3 and FIG. The amount of data can be divided and copied.

  Next, when there are a plurality of types of copy destination recording media (for example, DVD 18 and SD card 20 as shown in FIG. 1) and division copying is performed on these different types (or states) of recording media, division copying is performed on the copy source data. An example of writing division information written as a history, that is, a correspondence table creation example will be described.

  FIG. 5 shows flags F1, F2,... As division information written to the user-desired content (copy source data) on the copy source HDD side at the time of execution of divided copy. When the user divides and copies the recording data for 2h for the first time from the copy source content of a predetermined size recorded in the HDD 16 (for example, 10 hours and 10h in the SP mode) to the DVD 18 having the remaining capacity for 2h. The division flag F1 is written in the copy source content. Then, for the second time, for example, the recording / reproducing apparatus main body 10 is turned on to enter the operation standby state on the next day, and when the SD card 20 having a free capacity of 1 h is selected as the copy destination recording medium and divided copying is performed, A division flag F2 is written in the content. Similarly, when the third copy is divided and copied to another DVD 18 having a free space of 2h, a division flag F3 is written in the copy source content. Next, as a fourth time, for example, when divided copying is performed on a DVD 18 that has been recorded for 30 minutes and has a remaining capacity of 1.5 hours, the remaining capacity for 1.5 hours is detected in the embodiment of the present invention. The copy source data is automatically divided to a size that falls within the range, and a division flag F4 is written in the copy source content. Furthermore, when the SD card 20 having a free space of 1 h is selected and dividedly copied for the fifth time, the division flag F5 is written in the copy source content. Similarly, 10h worth of copy source content can be divided and copied to a plurality of recording media of different types and recording states according to the remaining capacity.

  According to the first embodiment described above, when the content recorded by the recording / playback apparatus is divided and copied, the division information indicating how far the content has been copied is written in the copy source content. It is possible to copy from the rest. Therefore, since the content of the copy source has the copied information, even if all of the content files are moved to another storage device different from the HDD 16 of the apparatus main body 10, the copy is continued from the storage device. Is possible.

  In the first embodiment described above, the example in which the division information is written in the copy source content of the HDD 16 and used as the correspondence table for the division copy has been described. However, each time for the entire size (or time) of the copy source content is described. A correspondence relationship table showing the relationship of the division positions (or division times) may be created and stored in a memory means (not shown) separate from the HDD 16. By configuring in this way, since the division information is not included in the copy source content on the HDD side, when you want to copy again from the beginning of the copy source content that has already been divided and copied, without worrying about the division information, It becomes easy to copy from the beginning.

  In the first embodiment described above, the DVD 18 and SD card 20 which are copy destination recording media are mounted on the recording / reproducing apparatus main body 10, and the remaining capacity is the state where the DVD 18 and SD card 20 are mounted on the apparatus main body 10. Thus, the CPU 11 detects the remaining capacity information. In contrast to such a configuration, the recording / reproducing apparatus main body 10 shown in FIG. 1 is connected to a portable DVD player or a pocket PC as shown in FIG. 2 using a USB connection cable or the like (or wirelessly). A configuration may be adopted in which data is copied from the apparatus main body (HDD side) 10 to each apparatus shown in FIGS. 2A and 2B in a state in which a DVD or SD card as a recording medium is mounted in a portable DVD player or a pocket PC. . However, when the copy source device and the copy destination device are connected via a connection cable or wirelessly in this way, first, a copy capacity request is sent from the copy source device CPU to the copy destination device CPU, and the copy received is received. The CPU of the destination apparatus notifies the CPU of the copy source apparatus by transmitting the remaining capacity information written in its own recording medium to the CPU of the copy source apparatus. In the case of such a connection cable or wireless connection configuration, the divided copy procedure is the same as that described in FIGS. 3 and 4 except that copy data from the copy source device is sent as communication data to the copy destination device. It is the same.

  Furthermore, in the above-described first embodiment, as an example in which large-size original data in the storage device is read and written to a recording medium with a small remaining capacity, the original data in the storage device is divided and copied so as to fit in the remaining capacity of the recording medium. However, the present invention is not limited to the case where divided copying is performed, and can also be used in the case where the original data of the storage device is divided and moved so as to fall within the remaining capacity of the recording medium. It is.

  In addition to a recording / playback device having a large-capacity storage device such as an image file device or a server device that stores video content or multimedia content, the present invention includes a hard disk built-in DVD recorder, digital camera, digital video camera, etc. The present invention can be widely applied to a recording / reproducing apparatus that records and reproduces video and / or audio data.
