Hereinafter, a recording apparatus will be described as an example of the recording apparatus.
Note that the present invention is not limited to the following embodiments.

Embodiment 1
FIG. 1 is a conceptual diagram showing the external appearance of the recording apparatus 1. The recording device 1 operated by a remote control (remote control) R records, for example, television broadcasting, cable television broadcasting, Internet broadcasting, and the like. A TV (television) receiver 4 is connected to the recording apparatus 1. The recording device 1 outputs a video signal and an audio signal indicating the recorded broadcast content to the TV receiver 4. The TV receiver 4 is a liquid crystal television including a backlight and a liquid crystal panel, for example. The TV receiver 4 displays video based on the received video signal and outputs audio based on the received audio signal.
In the example of FIG. 1, the recording apparatus 1 and the TV receiver 4 are shown as separate bodies, but the recording apparatus 1 and the TV receiver 4 may be integrated.

FIG. 2 is a block diagram showing an internal configuration of the recording apparatus 1. The recording device 1 includes a drive device 2 and a back-end device 3.
The drive device 2 includes a disk drive (duplicating unit) 21, a drive recording unit (recording unit) 22, a drive control unit 23, and an interface unit 24.

A disc D having portability such as a DVD or a BD is detachably inserted into the disc drive 21. The disk drive 21 reads the video data recorded on the disk D and outputs it to the back-end device 3. The disk drive 21 records the video data input thereto on the inserted disk D.
The recording mode is not limited to recording video data on the disk D using the disk drive 21. For example, the form of recording may be a form in which a portable hard disk, a memory card, a flash memory, or the like is connected to or built in the drive device 2 instead of the disk drive 21.

The disk D has a unique disk ID. The disk ID is, for example, a manufacturing number, a serial number, or the like recorded on the disk D when the disk D is manufactured.
Note that the identification information of the disk D is not limited to the disk ID recorded in advance on the disk D when the disk D is manufactured. For example, the recording apparatus 1 may include means for writing identification information of the recording medium on the recording medium. As identification information in this case, various information such as a combination of a disc owner name and a sequence number, a time stamp, and the like may be used.

  The drive recording unit 22 includes a nonvolatile memory such as an EEPROM (Electrically Erasable and Programmable ROM), a flash memory, and a FeRAM (Ferroelectric RAM), or a hard disk. The recording capacity of the drive recording unit 22 is, for example, twice the recording capacity of the BD.

  In the drive recording unit 22, a recording area 22 a in which the owner name and content of the disc D can be recorded in association with the disc ID of the disc D is prepared by the back-end device 3. The recording area 22a associated with the disc ID is managed in a one-to-one relationship with the disc D on which the disc ID is recorded. Therefore, the number of recording areas 22a is the same as the number of disks D.

Further, in the recording area 22a associated with the disc ID, for example, a title, reproduction time, broadcast time, program information, and part or all of the content data of the recorded content are recorded. Here, part of the content data is data that can be repeatedly played back for a certain period of time from the start of the content program, for example. The data is used to display a list of video thumbnails related to the content on the TV receiver 4.
When new data is recorded in the recording area 22a or the disk D, a synchronization process is performed between the recording area 22a and the disk D on which the disk ID is recorded so that no data mismatch occurs. .

The drive control unit 23 is a processor such as a CPU (Central Processing Unit) and an MPU (Micro Processor Unit), and controls each component of the drive device 2.
The interface unit 24 is an interface of SATA (Serial Advanced Technology Attachment) standard or ATA (Serial Advanced Technology Attachment) standard, and is connected to the back-end device 3.
The drive device 2 exchanges data with the back-end device 3 via the interface unit 24. Each component of the drive device 2 is connected to the system bus 2b, and data is transferred according to an instruction from the drive controller 23.

The back end device 3 includes a digital tuner 31, an encoder 32, and a stream processing unit 33.
The digital tuner 31 receives broadcast signals such as BS (broadcast satellite) digital broadcast, CS (communication satellite) digital broadcast, and terrestrial digital broadcast received by the external antenna A. The digital tuner 31 converts a selected channel, that is, a broadcast signal of a specific frequency band among received broadcast signals into digital stream data such as MPEG (Moving Picture Experts Group) -2TS (Transport Stream).

  The encoder 32 receives a video signal and an audio signal from an external playback device, a server device connected via a network, a cable television line, or the like. The encoder 32 performs processing for encoding a video signal and an audio signal received from the outside into digital stream data such as MPEG-2PS (Program Stream) and MPEG-2TS.

  The stream processing unit 33 is connected to the digital tuner 31 and the encoder 32 and receives stream data from the digital tuner 31 and the encoder 32. The stream processing unit 33 performs data processing such as processing for releasing scramble for digital broadcasting on the received stream data.

When viewing the content related to the received stream data, the stream processing unit 33 outputs the stream data subjected to the data processing to the decoder 36 described later. The stream processing unit 33 outputs the stream data subjected to the data processing to the drive device 2 when recording the content related to the received stream data.
Both the output from the stream processing unit 33 to the decoder 36 and the output from the stream processing unit 33 to the drive device 2 may be executed at the same time, or only one of them may be executed. Further, the stream data output to the decoder 36 and the stream data output to the drive device 2 may be the same or different.

The back-end device 3 includes a back-end control unit (duplication unit, detection unit, determination unit, remaining capacity detection unit, recording determination unit, deletion unit) 34, a back-end recording unit 35, a decoder 36, a video processing unit 37, and an interface. Part 38 is included.
The back-end control unit 34 is a processor such as a CPU or MPU, and controls each component of the back-end device 3.
The back-end recording unit 35 includes a nonvolatile memory and a volatile memory, and records programs executed by the back-end control unit 34, work variables, temporary information, and permanent information. The information recorded by the back-end recording unit 35 is, for example, program recording reservation information, data management information recorded by the drive recording unit 22, and the like.

The decoder 36 receives stream data from the stream processing unit 33 or the drive device 2. The decoder 36 decodes the received stream data into a video signal and an audio signal, and outputs the decoded video signal and audio signal to the video processing unit 37. When the decoder 36 receives the stream data for thumbnails associated with the disk ID from the drive device 2, the decoder 36 decodes the received stream data into thumbnail video signals and outputs the decoded video signals to the video processing unit 37. .
Since the thumbnail is a reduced image, even if the image quality is lowered, it is not noticeable to the viewer. Accordingly, the video data for thumbnails may be subjected to thinning processing such as reducing the number of pixels.

  The video processing unit 37 receives a video signal and an audio signal from the decoder 36, and executes image processing such as pixel interpolation or color adjustment on the received video signal. The video processing unit 37 outputs the video signal and audio signal subjected to image processing to the external TV receiver 4 via an interface (not shown). In addition, when receiving a thumbnail video signal from the decoder 36, the video processing unit 37 generates a video signal for displaying a list of thumbnails grouped for each disk ID, and outputs the generated video signal to the external TV receiver 4. .

The interface unit 38 is an SATA standard or ATA standard interface and is connected to the drive device 2.
The back-end device 3 exchanges data with the drive device 2 via the interface unit 38.

The back end device 3 includes a time measuring unit 39 and a receiving unit 40.
The time measuring unit 39 measures time, date, and day of the week.
The receiving unit 40 receives signals related to various operations from the external remote controller R by, for example, an infrared method, a Bluetooth (registered trademark) method, an RF (Radio Frequency) method, and the like, and receives the received signals to the back-end control unit 34. Output.
The stream processing unit 33, the back-end control unit 34, the back-end recording unit 35, the decoder 36, the interface unit 38, and the time measuring unit 39 are connected on the system bus 3b. Delivery takes place.

  The back-end control unit 34 outputs a control signal for controlling each component of the drive device 2 to the drive control unit 23 of the drive device 2 based on a signal received from the remote controller R via the reception unit 40. The drive control unit 23 receives the control signal output from the back-end control unit 34, and controls each component of the drive device 2 based on the received control signal. That is, the back end control unit 34 indirectly controls each component of the drive device 2.

The control of the drive device 2 is not limited to the configuration in which the back end control unit 34 and the drive control unit 23 are performed in cooperation. For example, the back-end control unit 34 may directly execute input / output of various data to the drive recording unit 22 without using the drive control unit 23. Alternatively, the drive control unit 23 may not be provided.
The recording apparatus 1 includes two recording units, that is, a drive recording unit 22 and a back-end recording unit 35. When one recording unit also serves as the other recording unit, the recording unit 1 and the back recording unit 35 are connected to each other. Either one of the end recording units 35 may be omitted.

Next, the operation of the recording apparatus 1 will be described.
First, a process for generating the recording area 22a in the drive recording unit 22 will be described.
When the disk D is inserted into the disk drive 21, the drive control unit 23 reads the disk ID from the inserted disk D. The drive control unit 23 outputs the read disk ID to the back-end control unit 34. The back-end control unit 34 searches the drive recording unit 22 for the recording area 22a corresponding to the received disc ID. When the recording area 22a corresponding to the read disk ID is not found, the back-end control unit 34 determines that a new disk D has been inserted into the disk drive 21, and the recording area 22a corresponding to the disk ID of the new disk D. Is created in the drive recording unit 22. Further, the owner name of the new disk D input from the remote controller R is recorded in the recording area 22a corresponding to the new disk ID by the back-end control unit 34.

Next, a recording process of the recording apparatus 1 performed before the automatic editing process will be described.
FIG. 3 is a flowchart showing a procedure of processing in which the recording apparatus 1 records a broadcast program. FIG. 3 shows the procedure of a process for recording a broadcast program in a reserved manner, but the same process is basically performed in a normal recording process.
Note that the broadcast program recording process is an example of a process in which the recording apparatus 1 records content, and the content recorded by the recording apparatus 1 is not limited to the broadcast program.

  The back-end control unit 34 starts preparation for program recording based on the reservation information recorded in the back-end recording unit 35 and the timing of the timing unit 39.

  The back-end control unit 34 records the program video in the recording area 22a corresponding to the user who has set the recording reservation (step S101). The back-end control unit 34 records the content information of the recorded program in the recording area 22a (step S102), and ends the process. The content information is, for example, a title, playback time, broadcast date and time, and program information.

  As described above, the program video is recorded in the recording area 22 a of the drive recording unit 22. For this reason, even if the user forgets to insert the disk D into the disk drive 21 even though the reserved recording is set, the recording of the program video does not fail.

  The recording capacity of the drive recording unit 22 is finite, and the recording capacity of recorded content is also finite. Therefore, when the number of content recordings increases and the remaining capacity of the drive recording unit 22 becomes smaller than a predetermined value, a state in which the content cannot be recorded in the recording area 22a of the drive recording unit 22 occurs. In order to prevent this, when the disc D is inserted into the disc drive 21, the back-end control unit 34 executes an editing process for moving the content recorded in the recording area 22a to the disc D. That is, when the remaining capacity of the drive recording unit 22 becomes a predetermined value or less, the back-end control unit 34 is recorded in the recording area 22a corresponding to the disc D when the disc D is inserted into the disc drive 21. The oldest content is moved to the disc D. This automatic editing process is automatically executed by the back-end control unit 34 without an instruction from the user.

  Note that the predetermined value that is one of the conditions for executing the automatic editing process described above may be a half of the recording capacity of the drive recording unit 22 or may be a quarter, and is not limited to a specific value. This predetermined value may be set in advance by the user in consideration of the recording capacities of the drive recording unit 22 and the disc D.

  FIG. 4 is an explanatory diagram regarding data before synchronization between the disk D and the drive recording unit 22. FIG. 5 is an explanatory diagram relating to data after synchronization is obtained between the disk D and the drive recording unit 22. 4 and 5, it is assumed that the process of step S102 in FIG. 3 has not been executed.

Before synchronization, content information A, B to X, a stream for thumbnails A and B to X, and new recording data Y are recorded in the recording area 22a of the disc ID = 1. On the other hand, recording data A, B to X are recorded on the disk D with the disk ID = 1, but Y recording data is not recorded.
The Y content information is created by the automatic editing process and the automatic synchronization process, and the created Y content information is recorded in the recording area 22a. Also, by the automatic editing process and the automatic synchronization process, the new recording data of the content Y is copied from the recording area 22a to the disk D, and the new recording data of the content Y is deleted from the recording area 22a. However, the head portion of the Y stream data is left so that the Y thumbnail stream remains in the drive recording unit 22, and the new recording data of Y is deleted for the other portions.
After synchronization, the content information of A, B to X and Y and the thumbnail streams of A, B to X and Y are recorded in the recording area 22a with the disc ID = 1. However, new recording data of Y is not recorded in the recording area 22a of the disk ID = 1. On the other hand, recorded data of A, B to X, Y is recorded on the disk D with the disk ID = 1.

  FIG. 6 is an explanatory diagram relating to recorded data recorded in the recording area 22a before and after synchronization. Note that FIG. 6 deals with the case where step S102 in FIG. 3 is executed.

Execution of step S102 does not change the point that the content information is held in the recording area 22a of the drive recording unit 22 before and after synchronization in FIG. Before the synchronization, new recorded content is recorded in the recording area 22a. The stream data of the newly recorded content recorded in the recording area 22a by the automatic editing process is copied to the disk D. Further, the stream data of the newly recorded content recorded in the drive recording unit 22 leaves the stream data for thumbnails, and the stream data of the other part is deleted.
When the recorded data is copied from the recording area 22a to the disk D by the automatic editing process and the automatic synchronization process, the remaining recordable capacity of the drive recording unit 22 is increased by deleting the data recorded in the recording area 22a. be able to.

FIG. 7 is a flowchart showing a procedure of automatic editing processing and automatic synchronization processing. FIG. 7 deals with the case where step S102 in FIG. 3 is executed.
When the disk D is inserted into the disk drive 21, the back end control unit 34 reads the disk ID from the disk D (step S201). The back end control unit 34 records the read disk ID in the back end recording unit 35 (step S202).
The back end control unit 34 detects the remaining capacity of the drive recording unit 22 (step S203). The back end control unit 34 determines whether or not the detected remaining capacity of the drive recording unit 22 is less than a predetermined value (step S204). If the back-end control unit 34 determines that the detected remaining capacity of the drive recording unit 22 is not less than the predetermined value (step S204: NO), the process ends. When the back-end control unit 34 determines that the remaining capacity of the detected drive recording unit 22 is less than the predetermined value (step S204: YES), the content of the content recorded in the recording area 22a corresponding to the inserted disc D The oldest content is specified (step S205). The back-end control unit 34 copies the identified oldest content to the disc D (step S206). The back-end control unit 34 deletes the content related to duplication from the recording area 22a while leaving the thumbnail stream (step S207), and ends the process.

If no content is recorded in the recording area 22a corresponding to the inserted disc D between step S204 and step S205, a step of ending the processing may be inserted.
Step S207 may be executed in parallel with step S206, or may be executed in parallel at a timing at which part of the end of step S206 overlaps.
In step S207, the back-end control unit 34 may perform marking that permits overwriting on the portion of the recording area 22a other than the remaining stream for the thumbnail without deleting the content related to the duplication from the recording area 22a. In other words, the duplication here is a broad sense duplication including both so-called movement and copying.

There may be various other modes of data synchronization between the disk D and the drive recording unit 22. This relates to what kind of processing is executed in the broadcast program recording processing shown in FIG.
FIG. 8 is an explanatory diagram of another example regarding data before synchronization between the disk D and the drive recording unit 22. FIG. 9 is an explanatory diagram of another example relating to data after synchronization has been established between the disk D and the drive recording unit 22. FIGS. 8 and 9 deal with a case where processing for recording a thumbnail stream for 30 seconds, for example, for 30 seconds from the start of the program is inserted into the recording area 22a before or after step S102 in FIG.

Before synchronization, content information A, B to Y, thumbnail streams A and B to Y, and new video recording data Y are recorded in the recording area 22a of disk ID = 1. On the other hand, recording data A, B to X are recorded on the disk D with the disk ID = 1, but Y recording data is not recorded.
Through the automatic editing process and the automatic synchronization process, the new recording data of Y is copied from the drive recording unit 22 to the disk D, and the new recording data of Y is deleted from the drive recording unit 22.
After synchronization, the A, B to Y content information and the A, B to Y thumbnail streams are recorded in the recording area 22a of the disc ID = 1. However, new recording data of Y is not recorded in the recording area 22a of the disk ID = 1. On the other hand, recording data of A and B to Y are recorded on the disk with the disk ID = 1.

According to the recording apparatus 1, data duplication processing can be automatically performed between the recording area 22 a of the drive recording unit 22 and the disk D.
For example, in the case of another recording device equipped with a hard disk, a dubbing operation is required when the program video recorded on the hard disk is stored in another recording medium. However, according to the recording apparatus 1, the trouble of such dubbing can be saved. That is, according to the recording apparatus 1, content is automatically dubbed from the recording area 22a to the disc D.

  According to the recording apparatus 1, when the video data of the content recorded in the recording area 22a is copied to the disk D, the recording is performed during the movement of the video data, after the movement of the video data, or from the movement of the video data to after the movement. The video data of the content to be moved is deleted from the area 22a. With this function that can be called automatic dubbing, the remaining capacity of the drive recording unit 22 can be increased. In addition, the video data deleted from the drive recording unit 22 is not all, but a part of the video data excluding thumbnail video data is deleted. For this reason, the video data for thumbnail remains in the recording apparatus 1. As a result, the user can display the content video as a thumbnail without inserting the disc D into the disc drive 21, and can check the content recorded on the disc D without the disc D.

  There are problems that make it difficult to realize simple operations of AV devices, such as elderly users who do not understand the concept of recording on a hard disk and who do not understand how to use the disk D. However, according to the recording apparatus 1, as long as the disc ID is registered in the recording area 22a of the drive recording unit 22, the content can be recorded in the recording area 22a. Even content can be enjoyed. In addition, since the user feels as if the content recorded in the recording area 22a is recorded on the disc D, it is possible to provide excellent operability even for a user who is unfamiliar with the handling of AV equipment. The automatic dubbing function described above ensures this excellent operability.

In the present embodiment, the oldest content recorded in the recording area 22a is copied to the disc D. However, the oldest content recorded in the recording area 22a is an example of content copied from the recording area 22a to the disc D. The content copied from the recording area 22a to the disc D may be the newest content recorded in the recording area 22a. Further, the content related to duplication may be the content with the largest recording capacity recorded in the recording area 22a or the content with the smallest recording capacity. Alternatively, the user may record in advance a rule for specifying the content related to duplication in a file or the like, and the back-end control unit 34 may specify the content related to duplication by referring to the file or the like.
Furthermore, the following forms may be used. When the remaining capacity of the drive recording unit 22 is larger than a predetermined value, two statuses, unviewed and viewed, are recorded for each content recorded in the recording area 22a. The back-end control unit 34 may specify content related to duplication from unviewed or viewed content.

Embodiment 2
The second embodiment relates to an automatic editing process when the remaining capacity of the inserted disc D is smaller than the recording capacity of the oldest content recorded in the recording area 22a.

  When the recording capacity of the inserted disc D is smaller than the recording capacity of the content to be copied, the back-end control unit 34 searches for the content recorded in the recording area 22a corresponding to the disc D, and records less than the remaining capacity of the disc D. Select capacity content. The back-end control unit 34 automatically copies the oldest content among the selected content to the disk D. Further, when the recording capacity of the disk D has a margin, the back-end control unit 34 selects a content that can be further copied and copies it to the disk D. The back-end control unit 34 confirms the recording capacity of the disk D and repeats this operation until there is no content that can be copied.

FIG. 10 is a flowchart illustrating the procedure of another example of the automatic editing process and the automatic synchronization process.
When the disk D is inserted into the disk drive 21, the back-end control unit 34 reads the disk ID from the disk D (step S301). The back end control unit 34 records the read disk ID in the back end recording unit 35 (step S302). The back end control unit 34 detects the remaining capacity of the drive recording unit 22 (step S303). The back end control unit 34 determines whether or not the detected remaining capacity of the drive recording unit 22 is smaller than a predetermined value (step S304). If the back-end control unit 34 determines that the detected remaining capacity of the drive recording unit 22 is not less than the predetermined value (step S304: NO), the process ends.

  When the back-end control unit 34 determines that the detected remaining capacity of the drive recording unit 22 is less than the predetermined value (step S304: YES), the back-end control unit 34 detects the remaining capacity of the disk D (step S305). The back end control unit 34 determines whether or not content having a recording capacity smaller than the remaining capacity of the disc D is recorded in the recording area 22a (step S306). When the back-end control unit 34 determines that content having a recording capacity smaller than the remaining capacity of the disc D is recorded in the recording area 22a (step S306: YES), the back-end control unit 34 matches the determination and determines the oldest content. Specify (step S307). The back-end control unit 34 copies the identified oldest content to the disc D (step S308). The back end control unit 34 deletes the content related to the duplication from the recording area 22a while leaving the thumbnail stream (step S309), and returns the process to step S303.

  When the back-end control unit 34 determines that no content having a recording capacity smaller than the remaining capacity of the disc D is recorded in the recording area 22a (step S306: NO), the process ends.

  If the back-end control unit 34 determines that content having a recording capacity smaller than the remaining capacity of the disc D is not recorded in the recording area 22a (step S306: NO), the process ends without performing the following process. Processing may be added. The additional process is a process of presenting an instruction to insert a new disk D into the disk drive 21 and returning to step S305.

  According to the recording apparatus 1, in consideration of the remaining capacity of the disc D, the content to be copied to the disc D is specified from the content recorded in the recording area 22 a corresponding to the disc D. As a result, duplication can be performed in units of content, and it is possible to avoid copying only partial data of the content to the disk D. In addition, since the duplication process is automatically repeated until there is no content that can be duplicated from the recording area 22a, the trouble of repeating the operation of inserting the disc D into the disc drive 21 is reduced. Furthermore, the repetition of automatic duplication processing can efficiently increase the recording capacity of the recordable drive recording unit 22.

  The second embodiment is as described above, and the other parts are the same as those of the first embodiment. Accordingly, the corresponding parts are denoted by the same reference numerals, and detailed description thereof is omitted.
