Description

  The present invention relates to a data recording apparatus that records data using, for example, an HDD (hard disk) and a DVD, and more particularly to movement control of recorded data. The present invention also relates to a data movement control method for controlling movement of recorded data.

  In recent years, recording / reproducing apparatuses such as DVD recorders equipped with HDDs have been widely used. Such a recording / reproducing apparatus can record one program as one title and can partially control the reproduction of the title by a reproduction unit called a chapter. In other words, one title is composed of a plurality of chapters. As a method of dividing chapters on one title, there are, for example, a method of automatically dividing chapters (every predetermined time) by a recording / reproducing apparatus, and a method of dividing chapters at arbitrary positions according to user designation.

  In addition, such a recording / playback apparatus can play a playlist based on a playlist that defines the playback order of a plurality of chapters. For example, by selecting several chapters from a plurality of chapters constituting one title and defining the playback order of these selected chapters by a playlist, only favorite scenes in one title are collected. Playback is possible. Also, by selecting several chapters from multiple chapters that make up multiple titles and defining the playback order of these selected chapters using a playlist, only the favorite scenes in multiple titles are collected. Playback is also possible.

From the viewpoint of copyright protection and the like, it is expected that copy-once programs replaced with copy-free programs will be widely spread in the future. The recording / reproducing apparatus as described above can record the copy once program (first recording), but the copy once program recorded by the recording / reproducing apparatus can be recorded in another recording destination (second recording). Can not. However, the copy-once program recorded by the recording / reproducing apparatus can be moved to another recording destination (see Patent Document 1).
JP2003-22610

  When moving the title of a copy-once program with a playlist defined to another recording destination, only the chapter specified by the playlist is extracted from a plurality of chapters constituting this title and moved to another recording destination. Conceivable. For example, such a movement can be considered when it is desired to use the created playlist at another recording destination.

  However, as a result of such movement, the chapters constituting one title of the movement source do not correspond to the one original program. It becomes a so-called worm-eaten title. In other words, if only the chapter specified by the playlist is extracted from the chapters that make up one title and moved to another recording destination, it corresponds to the original program at the destination or source. There was a problem that it could not be played back.

  In addition, as described above, a playlist can be set for a plurality of titles, and only the chapters designated by the playlist set for the plurality of titles are extracted and moved to another recording destination. If you do, the problem becomes even more serious. That is, a plurality of titles become worm-eaten.

  An object of the present invention is to solve the above-described problem, and it is impossible to reproduce an entire program by moving data corresponding to an instruction to extract a part of reproduced data constituting one program. It is an object of the present invention to provide a data recording apparatus and a data movement control method that can prevent this from happening.

  The data recording apparatus and data movement control method of the present invention are configured as follows.

  (1) A data recording apparatus according to the present invention comprises a recording means for recording reproduction data composed of a plurality of unit data, and at least one of unit data belonging to the recorded reproduction data is recorded in another manner. Instruction means for instructing movement to the apparatus, detection means for detecting reproduction data to which the unit data instructed to move belongs, and movement means for moving the detected reproduction data to the other recording apparatus I have.

  (2) In the data movement control method of the present invention, an instruction is given to move at least one of unit data belonging to reproduction data composed of a plurality of unit data to another recording device, and the movement is instructed. The playback data to which the unit data belongs is detected, and the detected playback data is moved to the other recording device.

  According to the present invention, a data recording apparatus and data capable of preventing the reproduction of one program from being disabled due to the movement of data corresponding to an instruction to extract a part of the reproduction data constituting one program A movement control method can be provided.

  Hereinafter, first and second embodiments of the present invention will be described with reference to the drawings. The contents shown in FIGS. 1 to 3 are common to the first and second embodiments.

  FIG. 1 is a block diagram showing a schematic configuration of a recording / reproducing apparatus (data recording apparatus) as an example of the present invention.

  As shown in FIG. 1, the recording / reproducing apparatus 1 includes an HDD 101, an IEEE 1394 I / F 102, a belonging title detection unit 201, a movement target chapter determination unit 202, a chapter order optimization unit 203, a movement control unit 204, and a control procedure information generation unit. 301, a control procedure information storage unit 302, an identification information display unit 303, a reproduction control unit 304, and an instruction input unit 305.

  FIG. 2 is a diagram showing a state in which the recording / reproducing apparatus 1 and DVHS (digital video) 2 shown in FIG. 1 are digitally connected by IEEE 1394 which is a digital interface.

  The recording / reproducing apparatus 1 is, for example, a DVD recorder that is a combined machine of HDD and DVD. That is, the recording / reproducing apparatus 1 has a function of recording a broadcast program on an internal medium such as an HDD or a DVD. The recorded program is managed as a recorded title (reproduction data), and a plurality of recorded titles can be managed simultaneously. Further, the recorded title can be managed by being divided into units (reproduction units) called chapters as necessary. The user can create a play list (play list) that defines the play order of any of a plurality of chapters included in one or a plurality of recorded titles. The recording / playback apparatus 1 plays back any chapter specified by the user in any playback order based on this playlist. Thereby, it is possible to view an arbitrary plurality of chapters in a desired reproduction order from one or a plurality of recorded titles recorded so far.

  FIG. 3 is a diagram illustrating an image of playlist reproduction based on a playlist. As shown in FIG. 3, one recorded title is composed of a plurality of chapters. The playlist designates the playback order of a plurality of arbitrary chapters selected from one or a plurality of recorded titles. FIG. 3 shows an example of a playlist that specifies the playback order of any of a plurality of chapters selected from a plurality of recorded titles.

  For example, it is assumed that three recording titles of a recording title 1, a recording title 2, and a recording title 3 recorded in the past are stored in the HDD built in the recording / playback apparatus 1. The recorded title 1 is assumed to be divided into chapters 1-1 and 1-2. Similarly, it is assumed that the recorded title 2 is divided into a chapter 2-1, a chapter 2-2, and a chapter 2-3. Similarly, it is assumed that the recorded title 3 is divided into a chapter 3-1 and a chapter 3-2.

  The user operates the recording / reproducing apparatus 1 to reproduce, for example, chapter 2-2, chapter 1-2, and chapter 3-1 in order from among a plurality of chapters included in the recorded titles 1, 2, and 3. A playlist can be created. When the user instructs the recording / playback apparatus 1 to play a playlist, the recording / playback apparatus 1 plays back chapter 2-2, chapter 1-2, and chapter 3-1 in order based on the playlist. As a result, the user can view a desired chapter in the order of the playlist.

  Next, movement control according to the first embodiment of the present invention will be described. FIG. 4 shows data recorded on the HDD of the recording / reproducing apparatus 1 based on the above-described playlist on the tape medium inserted in the DVHS 2 digitally connected to the recording / reproducing apparatus 1 (data permitted to be copied only once). It is a flowchart which shows the data movement process which moves.

  For example, it is assumed that the user instructs data movement based on the playlist via the instruction input unit 305 (ST101). That is, it is assumed that movement of at least one chapter constituting the recording title is instructed.

  Correspondingly, the affiliation title detection unit 201 detects all recorded titles to which the chapters whose playback order is specified by the playlist (ST102), and each chapter whose playback order is specified by the playlist, Each chapter included in the detected recorded title and whose playback order is not specified by the playlist is registered as a movement target in the movement target chapter determination unit 202 (ST103).

  In the first embodiment, the chapter 2-2 whose playback order is specified by the playlist is registered in the movement target chapter determination unit 202 as a movement target, and is further included in the recorded title 2 to which this chapter 2-2 belongs. Chapters 2-1 and 2-3 other than Chapter 2-2 are also registered in the movement target chapter determination unit 202 as movement targets. Similarly, the chapter 1-2 whose playback order is specified by the playlist is registered in the movement target chapter determination unit 202 as the movement target, and further, the chapter 1- 1 included in the recorded title 1 to which this chapter 1-2 belongs. Chapters 1-1 other than 2 are also registered in the movement target chapter determination unit 202 as movement targets. Similarly, the chapter 3-1 whose playback order is specified by the playlist is registered in the movement target chapter determination unit 202 as a movement target, and further, the chapter 3 included in the recorded title 3 to which this chapter 3-1 belongs. Chapters 3-2 other than −1 are also registered in the movement target chapter determination unit 202 as movement targets.

  That is, the movement target chapter determination unit 202 includes chapters 2-2, chapters 1-2, and chapters 3-1 (a plurality of chapter data groups arranged in accordance with the playlist playback order) whose playback order is specified by the playlist. In addition, chapter 1-1, chapter 2-1, chapter 2-3, and chapter 3-2 (a plurality of remaining chapter data groups whose playback order is not determined by a playlist) are registered as movement targets.

  Subsequently, the chapter order optimization unit 203 rearranges the chapters registered in the movement target chapter determination unit 202 in the order of movement (ST104). For example, the chapters are arranged based on the reproduction order designated by the play list, and the remaining chapters whose reproduction order is not designated by the play list are arranged successively.

  FIG. 5 is a diagram for explaining the rearrangement process performed by the chapter order optimization unit. In the first embodiment, first, chapter 2-2, chapter 1-2, and chapter 3-1 are arranged in the order of the playlist, and then the remaining chapter 1-1, chapter 2-1, and chapter 2 are arranged. -3, chapter 3-2 are arranged.

  Subsequently, the movement control unit 204 controls movement of each chapter to the digitally connected DVHS 2 in the order optimized by the chapter order optimization unit 203 (in the order shown in FIG. 5) (ST105). The movement control unit 204 controls the DVHS 2 that is digitally connected to the recording start state, and then starts to transfer the first chapter. After the transfer is completed, the movement control unit 204 controls the DVHS 2 to a recording pause state or a recording stop state. Thereby, a marker signal (VISS marker) indicating a chapter break is recorded on the tape inserted in the destination DVHS 2, and it is convenient that the cueing operation is facilitated later when reproducing on the DVHS 2 side. Subsequently, the movement control unit 204 controls the movement of the chapters in the next order. After the recording control of the marker signal, the movement control unit 204 also controls the movement of the subsequent chapters in the same manner to control the movement of all the chapters.

  In this embodiment, an AV / C command defined for externally controlling a device connected by IEEE 1394 is used. First, the recording / reproducing apparatus 1 uses the RECORD command to cause the DVHS 2 to start recording and to transfer the first chapter. After the transfer is completed, the recording / reproducing apparatus 1 controls the recording stop of the DVHS 2 with a WIND (STOP) command. Similarly, the recording / reproducing apparatus 1 moves the chapters after the first chapter with respect to DVHS2.

  With the above movement control, chapters based on the playlist can be moved, and the remaining chapters included in the recorded titles to which the chapters specified by the playlist belong can also be moved. As a result, playback corresponding to the playlist can be performed at the destination, and all chapters included in the original recorded title can also be played back. That is, it is possible to prevent a plurality of chapters constituting the original recorded title from being dispersed at the movement destination and the movement source. If multiple chapters that make up the original recorded title are dispersed, only a part of the chapters that make up the original recorded title can be played at both the destination and the source, making usability worse. .

  Next, movement control according to the second embodiment of the present invention will be described. FIG. 6 shows data recorded on the HDD of the recording / reproducing apparatus 1 based on the above-described playlist on the tape medium inserted in the DVHS 2 digitally connected to the recording / reproducing apparatus 1 (data permitted to be copied only once). It is a flowchart which shows the data movement process which moves.

  For example, it is assumed that the user instructs data movement based on the playlist via the instruction input unit 305 (ST201). That is, it is assumed that movement of at least one chapter constituting the recording title is instructed.

  Correspondingly, the affiliation title detection unit 201 detects all recorded titles to which each chapter whose playback order is specified by the playlist (ST202), and each chapter whose playback order is specified by the playlist, Then, each chapter that is included in the detected recorded title and whose playback order is not specified by the playlist is registered as a movement target in the movement target chapter determination unit 202 (ST203).

  In the second embodiment, the chapter 2-2 whose playback order is specified by the playlist is registered in the movement target chapter determination unit 202 as a movement target, and is further included in the recorded title 2 to which this chapter 2-2 belongs. Chapters 2-1 and 2-3 other than Chapter 2-2 are also registered in the movement target chapter determination unit 202 as movement targets. Similarly, the chapter 1-2 whose playback order is specified by the playlist is registered in the movement target chapter determination unit 202 as the movement target, and further, the chapter 1- 1 included in the recorded title 1 to which this chapter 1-2 belongs. Chapters 1-1 other than 2 are also registered in the movement target chapter determination unit 202 as movement targets. Similarly, the chapter 3-1 whose playback order is specified by the playlist is registered in the movement target chapter determination unit 202 as a movement target, and further, the chapter 3 included in the recorded title 3 to which this chapter 3-1 belongs. Chapters 3-2 other than −1 are also registered in the movement target chapter determination unit 202 as movement targets.

  That is, the movement target chapter determination unit 202 includes chapters 2-2, chapters 1-2, and chapters 3-1 (a plurality of chapter data groups arranged in accordance with the playlist playback order) whose playback order is specified by the playlist. In addition, chapter 1-1, chapter 2-1, chapter 2-3, and chapter 3-2 (a plurality of remaining chapter data groups whose playback order is not determined by a playlist) are registered as movement targets.

  Subsequently, the chapter order optimization unit 203 rearranges the chapters registered in the movement target chapter determination unit 202 in the order of movement (ST204). For example, the chapters are arranged based on the configuration of all the recorded titles to which the chapters whose playback order is specified by the playlist belong.

  FIG. 7 is a diagram for explaining the rearrangement process performed by the chapter order optimization unit. Each recorded title is played back in a basic playback order corresponding to the recording order. For example, the basic playback order of the recorded title 1 is that chapter 1-1 is played back and chapter 1-2 is played back. The basic playback order of the recorded title 2 is that chapter 2-1 is played back, chapter 2-2 is played back, and further chapter 2-3 is played back. The basic playback order of the recorded title 3 is that chapter 3-1 is played back and chapter 3-2 is played back.

  That is, based on the configuration (basic playback order) of the recording title 1, the recording title 2, and the recording title 3, the chapter 1-1, the chapter 1-2, and the chapter 2- that configure the recording title 2 are included. 1, chapter 2-2, chapter 2-3, chapter 3-1 and chapter 3-2 constituting the recorded title 3 are arranged in this order.

  Subsequently, the movement control unit 204 controls movement of each chapter to the digitally connected DVHS 2 in the order optimized by the chapter order optimization unit 203 (in the order shown in FIG. 7) (ST205). The movement control unit 204 controls the DVHS 2 that is digitally connected to the recording start state, and then starts to transfer the first chapter. After the transfer is completed, the movement control unit 204 controls the DVHS 2 to a recording pause state or a recording stop state. Thereby, a marker signal (VISS marker) indicating a chapter break is recorded on the tape inserted in the destination DVHS 2, and it is convenient that the cueing operation is facilitated later when reproducing on the DVHS 2 side. Subsequently, the movement control unit 204 moves the chapters in the next order in the same manner. After the recording control of the marker signal, the movement control unit 204 also controls the movement of the subsequent chapters to move the movements of all the target chapters.

  In this embodiment, an AV / C command defined for externally controlling a device connected by IEEE 1394 is used. First, the recording / reproducing apparatus 1 uses the RECORD command to cause the DVHS 2 to start recording and to transfer the first chapter. After the transfer is completed, the recording / reproducing apparatus 1 controls the recording stop of the DVHS 2 with a WIND (STOP) command. Similarly, the recording / reproducing apparatus 1 moves the chapters after the first chapter with respect to DVHS2.

  With the above movement control alone, reproduction corresponding to a playlist cannot be realized even if reproduction is started from the beginning of the tape that is the movement destination. Therefore, the control procedure information generation unit 301 creates control procedure information for realizing reproduction corresponding to the playlist based on the order optimized by the chapter order optimization unit 203 (ST206). That is, the control procedure information is created based on the playlist so that the chapters arranged according to the basic playback order are played back in the playback order determined by the playlist.

  The control procedure information is mainly information for controlling cueing processing (forward skip, backward skip) and playback processing using a marker signal indicating a break between chapters recorded on the tape. An example of the control procedure information created by the control procedure information generation unit 301 is shown in FIG.

  For example, (1) to (6) are controlled to reproduce in the order of chapter 2-2, chapter 1-2, and chapter 3-1, which are the reproduction order specified by the playlist.

(1) Skip three chapters in the forward direction from the beginning of the tape and cue chapter 2-2.

(2) Play back chapter 2-2.

(3) Skip three chapters in the reverse direction from the end of chapter 2-2 and cue chapter 1-2.

(4) Play chapter 1-2.

(5) Skip three chapters in the forward direction from the end of chapter 1-2 and cue chapter 3-1.

(6) Play back chapter 3-1.

  It is assumed that a plurality of the control procedure information is created. The control procedure information generating unit 301 assigns identification information to each control procedure information so that the plurality of control procedure information can be identified (ST207). That is, the control procedure information and the identification information are stored in pairs in the control procedure information storage unit 302, and the target control procedure information can be called by inputting the identification information. Also, identification information is displayed by the identification information display unit 303 so that the user can call necessary control procedure information later. FIG. 8 is a diagram illustrating an example of display of identification information by the identification information display unit.

  The user stores the identification information displayed by the identification information display unit 303 by a method such as filling in the label on the tape. Thus, the DVHS 2 side tape can be reproduced based on the control procedure information corresponding to the identification information, relying on the identification information. That is, the DVHS 2 side tape can be played back in the playback order according to the playlist.

  Here, an operation in the case of reproducing a tape after movement of data based on a playlist will be described. The user instructs playback of the tape from the menu using a remote controller (instructed via the instruction input unit 305), and further performs normal playback in order from the beginning of the tape or a playlist based on the original playlist. Instructs whether to perform reproduction (instructed via the instruction input unit 305).

  When play list reproduction is instructed by the user, for example, an input screen for identifying information necessary for calling control procedure information is activated on the instruction input unit 305. FIG. 9 is a diagram illustrating an example of an input screen for identification information. When predetermined identification information is input via the instruction input unit 305, the reproduction control unit 304 calls the control procedure information from the control procedure information storage unit 302 based on the input identification information, and the DVHS2 side based on this control procedure information The reproduction of the tape is controlled (ST208). Thereby, the reproduction control according to the original playlist is realized.

  The first and second embodiments have been described above. The main difference between the two is an optimization process performed by the chapter order optimization unit 203. Either one of the optimization processing corresponding to the first embodiment and the optimization processing corresponding to the second embodiment may be fixed, or the user may perform either optimization processing. You may make it select. The selection of either optimization process is performed via the instruction input unit 305. The chapter order optimization unit 203 executes the optimization process selected via the instruction input unit 305.

  As described above, the recording / reproducing apparatus 1 of the present invention moves all the recorded titles to which each chapter to which the reproduction order is specified by the playlist belongs when moving the data recorded in the HDD of the recording / reproducing apparatus 1 based on the playlist. To do. As a result, it is possible to prevent a situation in which the recorded title from which the chapter is partially missing remains on the recording / reproducing apparatus 1 side after moving and the usability is deteriorated. In addition, since the chapter is moved based on the playlist, the user can perform reproduction corresponding to the playlist at the destination without performing any special operation. Alternatively, by generating the control procedure information based on the playlist, the user can reproduce the playlist corresponding to the playlist at the movement destination based on the control procedure information without performing any special operation.

  Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention in the implementation stage. In addition, the embodiments may be appropriately combined as much as possible, and in that case, the combined effect can be obtained. Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent requirements are deleted from all the constituent requirements shown in the embodiment, the problem described in the column of the problem to be solved by the invention can be solved, and the effect described in the column of the effect of the invention Can be obtained as an invention.
