  215 is a speaker driver for outputting sound, 216 is a speaker, and 217 is an external input / output terminal for inputting / outputting various information. The first recording / reproduction control circuit 223 and the second recording / reproduction control circuit 224 are control circuits for controlling recording / reproduction of the recording medium. 101 is a first recording medium, and 102 is a second recording medium. A CPU 230 controls the system. Reference numeral 222 denotes a memory for storing data for the CPU 230 and the system, and reference numeral 221 denotes a power supply apparatus that supplies power for operating each unit of the imaging apparatus 200.

First, an outline of the recording operation in the imaging apparatus 200 configured as described above will be described.
In the image, light from a subject incident through the lens 201 is converted into an electrical signal by the solid state sensor 202. Then, it is sampled by an A / D converter (A / D converter) 203 and converted into digital data of a moving image.

  The digital data is input to the CPU 230 as a digital video signal such as luminance Y, color difference Cr, Cb, or RGB signal. The lens 201 is moved by driving the motor 204 by a control command of the CPU 230 by an autofocus function and a zoom function. A timing signal for extracting data from the solid state sensor 202 is generated by the CPU 230.

  The opening degree of the iris 205 is controlled by the driving of the motor 204 by the CPU 230. The operation when the lens 201 has an anti-vibration function (acceleration sensor, anti-vibration actuator, etc.) is not shown in the figure, but the position sensor of the acceleration sensor and the anti-vibration actuator is input to the CPU 230. Done. For example, when the image stabilization control output signal is output from the CPU 230, the motor 204 is driven and controlled for the image stabilization actuator.

  In the audio system, an audio signal obtained from the microphone 209 functioning as an audio input unit is amplified by the microphone amplifier 210, then sampled by the A / D converter 211, converted into digital data, and input to the CPU 230. The

  The digital video signal is subjected to basic processing such as color separation, white balance, gamma correction, and aperture correction by the CPU 230 and additional processing such as image size, image quality adjustment, and position adjustment set by the operation key 212 of the imaging apparatus 200. . Furthermore, image compression processing such as MPEG, MJPEG, JPEG, JPEG2000, H264, etc. is performed according to the set compression method and compression parameters to obtain compressed image data. The audio data is subjected to additional processing such as sound quality adjustment set by the operation key 212 of the imaging apparatus 200, and audio compression data is obtained by the set compression method and compression parameters.

  In this embodiment, the MPEG standard is used for the compressed image data and the compressed audio data, and the stream format is defined by the MPEG standard together with the control data, and a data stream is formed as a program stream or a transport stream. The control data means photographing additional information such as information on the imaging apparatus itself, recording setting information such as images and sounds, and photographing environment information.

  The recording data stream is written as needed to the first recording medium 101 and the second recording medium 102 as a content file in a folder, which will be described later, as a file under file system management such as UDF or FAT. This writing is performed under the control of the first recording / reproducing control circuit 223 and the second recording / reproducing control circuit 224.

  When an operator operates the operation key 212 to stop recording, the recording of data on the first recording medium 101 and the second recording medium 102 is stopped, and the recorded data is registered and updated in the management file. do. In the present embodiment, the operator can select whether to record data on the first recording medium 101 or the second recording medium 102 by operating the operation key 212. Further, it is possible to record on both the first recording medium 101 and the second recording medium 102.

  The file system means a structure system composed of management information and file data for managing files. By sharing this file system, recording and playback can be performed on different recording media or recording and playback devices. The recording data is sent to the external input / output terminal 217 as necessary. Further, it is displayed on the display 214 through the display driver 213 for confirmation.

  The power supply of the imaging device 200 is supplied from the power supply device 221 and supplied to each circuit block. As the first recording medium 101 and the second recording medium 102, various memory cards, magnetic such as a hard disk, CD-RW, FD, MD, DVD-RAM, or an optical recording medium can be considered. Also, any of the above may be either fixed to the apparatus or removable.

In this embodiment, an example in which a hard disk is used as the first recording medium 101 and an optical disk is used as the second recording medium 102 will be described.
In this embodiment, the hard disk 101 is built in the imaging apparatus 200, and the optical disk 102 can be easily mounted and ejected using an unillustrated attachment / detachment mechanism, but any recording medium is built in the imaging apparatus 200. It may be configured. Conversely, any recording medium may be configured so that it can be easily ejected from and attached to the imaging apparatus 200.
Next, an image of data recorded on the hard disk 101 and the optical disk 102 will be described.

  FIG. 2 shows the appearance of the disk-shaped optical disk 102, and the recorded data is recorded as digital data on concentric circles. 2 is a hole for chucking when the disk is rotated. In FIG. 2, section B is a management area for recording data for managing data written in the disc. 2 is a data area in which actual recording information data is written. In FIG. 2, portions D and E show how actual recording data is written. For data recording, single-sided, double-sided, double-layered, multilayered surface, or the like is used.

  FIG. 3 shows an example of a folder of files recorded on the first recording medium 101 or the second recording medium 102. In FIG. 3, there are folders for VIDEO, DCIM, and MISC under the ROOT folder. A management folder MANAG folder is located under the VIDEO folder, and a disk.inf file describing the attributes of the recording medium and the like is located below the management folder MANAG folder.

  A file mgri001.inf for managing a content file recorded on a recording medium, which will be described in detail later, manages the content file on the recording medium with the file. In addition, a content file group and an img0001.thm file for collectively recording representative images of the content file group recorded on the recording medium are placed under the PRG0001 folder under the VIDEO folder. Also, img0001.mp7 for collectively recording the title of the content group recorded on the recording medium, a search table, additional information, maintenance information, and the like is placed.

  The search table creates a hash table using the content file attributes, title, date, incidental information, and the like as keys. As an example of content file, MPEG data file img0001.mpg. An information file img0001.inf describing the time stamp, structure information, etc. of the MPEG data stream. MPEG audio data file img0002.mp2. JPEG still image file img0004.jpg. Text data file img0005.txt. Bitmap image file img0006.bmp. Using the content recorded on the recording medium, a playlist file img0007.smi and the like describing the scene are recorded.

  When the number of content files or the number is greater than or equal to a predetermined value or when a predetermined condition is changed, a folder is newly created as PRG0002 under the VIDEO folder, and the content file is arranged under the folder. For example, when the recorded content file is an MPEG data stream, the content file number is obtained by adding “+1” to the previously recorded content file number as the file name.

  For example, the file name is img008.mpg and recorded at the location of \ VIDEO \ PRG0001 \. In this case, the MPEG2 file records the stream information file obtained at the time of creating the MPEG2 file together as an img0008.inf file. It is also possible to place content defined by each standard under DCIM defined by DCF and MISC folder defined by DPOF under ROOT.

Next, details of the content management file mgri001.inf will be described.
The content file managed by the content management file can be a case where a folder and a file group below the VIDEO folder described in FIG. 3 are managed, and a case where a folder and a file group of all recording media below the ROOT are managed. Furthermore, it is conceivable to link to a file other than the recording medium, for example, a content file on an intranet or the Internet. In this embodiment, ROOT and below are managed.

  FIG. 4 shows a content management file (index file) in which incidental information is described. The incidental information includes management information such as index type information, valid index identifier, standard version, compatibility level, and recording medium unique number at the head of the mgri001.inf index file. Also, file size, number of used indexes, maximum number of indexes, date information such as creation, update, and access, creator, text information, resume information, and the like.

  FIG. 5 shows the contents of each index, describing attributes, index numbers, additional information extended indexes, thumbnail index file names, additional information on the contents, file resume information, content protection information, and other information to be described later. The

  Examples of attributes are 0x01 for MPEG1, 0x02 for MPEG2, 0x03 for MPEG4, 0x80 for playlists, and 0x90 for effects. Also, 0xC0 to 0xFE are described as reservations. Furthermore, 0xFF is specified as a manufacturer-specific extended attribute. Regarding the file name, when the same file name is handled in another folder, it is necessary to describe the file name with a full path, but in this case, management becomes complicated. Therefore, management can be facilitated by adding attributes to file names for management. For example, the attributes are defined as VIDEO folder = 0x00, DCF folder = 0x01,..., Device external folder = 0x80, and the like.

Next, details of the content protection information will be described.
The content protection information includes copyright information, editability information, copy restriction information, and the like for the recorded content. Among them, the copy restriction information records information such as a copy process permission / prohibition flag, a one-time copy permission / prohibition flag, and a movement permission / prohibition flag, and protects recorded contents. Information is recorded.

  Each index may be either a fixed length or a variable length. In the case of a variable length, size information is added to each index. In addition, the fixed length and variable length sizes are set to N times the sector and cluster size of the file system, thereby facilitating file access.

Next, an outline of a basic moving image playback operation in the configuration of FIG. 1 will be described.
Description will be given of a case where a specified file in a recording medium selected by the operator by operating the operation key 212 in the content file group recorded on the first recording medium 101 or the second recording medium 102 is reproduced. To do.

  First, the content management file mgri001.inf is transferred from the designated first recording medium 101 or second recording medium 102 under the control of the first recording / reproducing control circuit 223 or the second recording / reproducing control circuit 224. Is read and analyzed. By analyzing the index of the management file, a list of moving image contents recorded in the recording medium can be obtained.

  An example in which the operator selects the designated file by operating the operation key 212 from the content list is displayed as a list on the display unit 214. For example, six representative images (thumbnail) from the top are selected from the moving image content list from img0001.thm in which the representative images are recorded collectively, and displayed on the display 214 as a list.

  When the operator operates the operation key 212 to select and specify a desired file and execute playback, first, the specified file is read from the content file group through the recording / playback control circuits 223 and 224. The read data is sent to the CPU 230, where the read data is analyzed and separated, and supplied to the image data portion, the sound data portion, the information data portion, and the like.

  The image data portion is for performing predetermined processing on the moving image data. When the moving image data to be processed is compressed, the image data portion is expanded and displayed on the display 214 through the display driver 213. The audio data section is for performing predetermined processing on the audio data. When the audio data to be processed is compressed, the audio data portion is expanded and sent to the speaker 216 through the speaker driver 215. Depending on the contents of the information data portion, processing such as image data and audio data effects and retouching are performed. Moreover, it displays on the display 214 as needed. The moving image data, audio data, and information data are also sent to the external input / output terminal 217.

Next, a resume information recording operation when the operator stops the reproduction by operating the operation key 212 during the moving image reproduction operation will be described.
If the operator operates the operation key 212 to stop playback during playback of moving image content, the CPU 230 executes stop processing and records resume information in the management file. In the present embodiment, when the resume information is recorded, a flag indicating that the resume information exists and the name or index number of the stopped execution are recorded in the management file mgri001.inf. Further, in the file resume information of the index indicated by the index number, the elapsed time from the beginning when playback is stopped or the address when playback is stopped is recorded as playback stop position information of the file.

  When the reproduction is instructed after the reproduction is stopped in this way, the CPU 230 reads and analyzes the management file mgri001.inf. It is determined from the management file information whether resume information is valid or invalid. If the result of this determination is that the file is valid, file resume information is acquired from the index information of the file instructed to be played, and playback is started from the playback stop position indicated by the resume information.

  The above describes the resume playback in the playback operation, playback stop, and playback start operation. However, in addition to this, when the playback operation, playback stop mode, recording, etc. mode transition, power OFF or removal of the recording medium, and then restarted in playback mode and playback starts, immediately after the previous playback stop It is also possible to start playback from.

The user can also disable the resume function by operating the operation key 212.
If there is an instruction to invalidate the resume function, the file resume information of the index indicated by the resume information of the management file mgri001.inf is cleared (in a state where no numerical value or instruction is given) at the time of the instruction to stop playback. Furthermore, the resume information can be erased by clearing and setting the resume information in the management file to invalid.

  In addition to the instruction from the user, the timing for deleting the resume information can be freely set as the operation specification of the imaging apparatus 200. For example, when reproduction is resumed, when a stop operation is performed twice in succession, when switching from reproduction to recording operation mode, when turning off the power, and the like are common.

Next, content copying and moving operations will be described.
Copying of content is an operation of copying content recorded on the first recording medium 101 or the second recording medium 102 to another recording medium. In this case, there are a case of copying to another recording medium in the imaging apparatus 200 and a case of copying content recorded on the recording medium to an external device through an external input / output terminal 217 such as a USB. For example, a case of copying to a personal computer, an external storage, a PC on a network, or a storage can be considered.

  On the other hand, the content is moved by recording the content recorded on the first recording medium 101 or the second recording medium 102 on another recording medium, and recording the content on the recording medium that is the movement source. Is an operation of erasing. In this case as well, when moving to another recording medium in the imaging apparatus 200 and erasing the content from the original recording medium, the content recorded on the recording medium is externally transmitted through an external input / output terminal 217 such as a USB. Move to equipment. Then, it may be possible to erase the original content.

  In this embodiment, a case where data recorded on the first recording medium 101 that is a hard disk is copied or moved to the second recording medium 102 that is an optical disk is described. However, a case where data is copied from the optical disk 102 to the hard disk 101 is also described. It is the same.

FIG. 7 is a diagram for explaining the outline of the copy operation.
When copying content from the recording medium A (hard disk 101 in the present embodiment) to the recording medium B (optical disk 102 in the present embodiment), the content data is recorded on the recording medium B. Further, the management data of the recording medium B is also updated with the copy to the recording medium B. However, the resume information accompanying the copied content data is not copied. In this case, when the resume information already exists in the recording medium B, the resume information is not erased and is retained in the recording medium B. However, depending on the specifications of the imaging apparatus 200, the resume information that has already been recorded on the recording medium B may be deleted, or the resume information on the recording medium A may be deleted.

FIG. 8 is a diagram for explaining the outline of the moving operation.
When moving content from the recording medium A to the recording medium B, the content data is recorded on the recording medium B, and the management data of the recording medium B is also updated as the content moves to the recording medium B. Resume information accompanying the content data recorded on the recording medium B is also read from the recording medium A and recorded on the recording medium B. After the content data and the resume information are recorded from the recording medium A to the recording medium B, the content data recorded on the recording medium B and the resume information associated with the content data are erased from the recording medium A. In addition, the management data of the recording medium A is updated.

FIG. 6 is a flowchart for explaining an example of the content copy operation or move operation according to this embodiment.
In FIG. 6, when there is an instruction to copy or move the content in step S101, the process proceeds to step S102, and a determination is made as to the copy instruction or the movement instruction. If the result of this determination is a movement instruction, the process advances to step S109 to determine whether there is a movement restriction on the accompanying information of the content.

  If the result of this determination is that there is a restriction on movement prohibition, it is displayed on the display 214 to notify the operator that the content cannot be moved due to movement prohibition, and then the operation proceeds to step S150 to end the operation. On the other hand, as a result of the determination in step S109, if the movement is permitted, the process proceeds to step S110, and the content movement operation described with reference to FIG. That is, the processing of “content movement” and “resume information movement” is executed.

  If the copy instruction is determined in step S102, the process proceeds to step S103, and it is determined whether or not there is a copy restriction in the content protection information in the incidental information of the content to be copied. If the result of this determination is that copying is prohibited, the information is displayed on the display 214 to notify the operator that copying cannot be performed because copying is prohibited. Next, notification of performing the moving operation is performed, and the process proceeds to step S109. In this state, it is possible to provide a selection means that allows the operator to select whether or not to perform the moving operation.

  On the other hand, if the result of determination in step S103 is that copying is permitted, the process proceeds to step S104, the content copying operation described in FIG. 7 is performed, and then the process proceeds to step S150 to finish the work.

  In the above description, the method for controlling the resume information associated with the content in the content copy / move processing has been described. However, in addition to the resume information, the reproduction operation state information associated with the content may also be copied or moved. In copying, the reproduction operation state information may not be copied, and the reproduction operation state information may be moved during movement. It is done. The reproduction operation state is information indicating a reproduction state such as the number of viewing times and reproduction environment information.

  As described above, when content data is copied, management data associated therewith is also updated, but resume information accompanying the content data is not copied. Further, when moving content, the content data is moved, management data associated therewith is updated, and resume information accompanying the content data is also moved. Accordingly, timely control of the resume function is executed without complicated settings by the operator, and thus a function with high convenience and operability can be provided.

  Further, by determining the content protection information attached to the content, it is possible to provide an effective resume function that is consistent for different purposes of copyright protection and resume function.

  In addition, by providing the imaging apparatus 200 with a selection unit that selects copying or moving of resume information, a function for an operator to manually set as needed can be provided. Furthermore, it is possible to provide a resume control function suitable for application not only to a recording / reproducing apparatus such as the imaging apparatus 200 described in the embodiment, but also to a device such as a video camera that inputs sound and images.

  As described above, according to the imaging apparatus 200 of the present embodiment, when content is moved for playback and viewing on another recording medium or another device, playback before moving is performed when playback and viewing is performed at the destination. The resume function that starts playback from the position is enabled. Also, when copying content to distribute it to others, the resume function does not work. For this reason, when the person to whom the content has been distributed reproduces the content, the resume function can be controlled in a timely manner without a complicated setting operation by the user. Thereby, a function with high convenience and operability can be provided.

  In addition, the copy and move process of the resume is controlled in a timely manner corresponding to the copyright protection of the content, so there is an effective resume function that is consistent for different purposes of the copyright protection and the resume function. Can be provided.

Furthermore, since the selecting means for selecting copy or movement of the resume information is provided, the operator can manually set the copy or movement of the resume information as necessary. Accordingly, it is possible to select resume information movement, copy, clear copy source resume information at the time of copying, and the like at the user's will.
