Description

  The present invention relates to a recording apparatus, and relates to an apparatus for recording information signals on a plurality of different recording media.

  Conventionally, a home video deck using a VHS magnetic tape as a recording medium has been widespread. In recent years, with the spread of personal computers, recording devices such as hard disks (hereinafter referred to as HDDs) have been increasing in capacity and price. Furthermore, the digitalization of such video equipment is also progressing, and the DV system is becoming mainstream especially in video cameras.

  Against this backdrop, the wave of digitization has also come to home video decks, and there are products that use optical discs such as rewritable DVD media and HDDs as recording media, encode image data using the MPEG2 system, and record / reproduce them. ing. Compared to conventional video cassettes that use magnetic tape as a recording medium, this includes many content management or playback that makes use of random accessibility, long-time recording, and simultaneous recording and playback that plays back recorded content while recording. There are benefits.

  In addition, many types of hybrid recorders equipped with removable optical disks and large-capacity HDDs have been commercialized and are becoming popular. In such a product, the user can select whether to record on an optical disk or an HDD. It is also possible to copy or move from one to the other.

  In addition, when the optical disc is selected as the recording medium and the scheduled recording is executed, if the optical disc is not loaded or the remaining amount is insufficient, the function of automatically recording from the head to the HDD, or recording on the optical disc, Some have a function of automatically starting recording on the HDD when the remaining amount becomes a predetermined amount or less. In this case, one content is recorded across the optical disc and the HDD.

Such a technique is described in Patent Document 1.
JP 2002-74839 A

  However, in the invention of Patent Document 1, when one content is recorded across the optical disc and the HDD, only the data recorded on the optical disc among the content recorded across the optical disc (hereinafter referred to as relay content) is transferred to another device. If you play with, you will not know whether it is the end or there is a continuation.

  Similarly, if this optical disc is not loaded in the recorder, when only the data recorded on the HDD of the relay content is played back, is the data of the first half of this content recorded separately? If it is relay content, there is no means for notifying the user of that fact.

  An object of the present invention is to solve such a problem and to make it easy to recognize that divided recording is performed even when one content is divided and recorded on a plurality of recording media. To do.

  In order to solve the above-described problems, the present invention provides a recording apparatus for recording information data, wherein the information data is recorded on a first recording medium that can be discharged outside the recording apparatus by a discharge mechanism. Recording means, second recording means for recording information data on a second recording medium that cannot be ejected outside the recording apparatus by the ejection mechanism, and the information data indicating a series of contents as the first After being recorded on the recording medium, it is recorded on the second recording medium, and the divided recording information data is divided and recorded on the first recording medium and the second recording medium. Control means for controlling the first recording means and the second recording means so as to generate identification information and record it on the first recording medium and the second recording medium; Information data and identification information Any one of the first reproducing means for reproducing, the second reproducing means for reproducing the information data and the identification information from the second recording medium, and any one of the first recording medium and the second recording medium Selecting means, and the control means selects the second recording medium by the selecting means and is instructed to start playback of the content recorded on the second recording medium. Accordingly, the divided recording information data corresponding to the divided recording information data recorded on the second recording medium based on the identification information recorded on the first recording medium and the second recording medium is the first recording medium. And whether or not the divided recording information data corresponding to the divided recording information data recorded on the second recording medium is recorded on the first recording medium , The divided record information The data was configured to control the first reproduction unit and the second reproducing means to reproduce from said second recording medium subsequent after playing from the first recording medium.

  According to the present invention, it is possible to know whether or not the separately recorded content is recorded on another recording medium, and the divided and recorded content can be easily reproduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of a recording / reproducing apparatus 100 to which the present invention is applied.

  Reference numeral 110 denotes a control unit that controls each unit of the recording / reproducing apparatus 100. The control unit 110 includes a microcomputer and a non-volatile memory (ROM) for storing a program thereof, a volatile memory (RAM) serving as a work area, an external bus for accessing data to other hardware and accessing a control register, At least a timer for measuring time is included.

  Reference numeral 103 denotes a bus. In addition to the external bus of the control unit 110, each block described later is connected to the bus 103, and is a transmission path that transfers data according to the control of the control unit 110. Reference numeral 101 denotes a tuner unit. The tuner 101 selects (selects) a channel from broadcast waves received via an antenna or cable according to the control of the control unit 110. Outputs the video signal of the selected channel. Reference numeral 102 denotes an encoder, which receives a video signal output from the tuner 101 during recording under the control of the control unit 110 and sequentially converts it into digital video data of the MPEG (Moving Picture Experts Group) system or the like.

  The digital video data is output from the address space of the bus 103 with the address designated by the control unit 110 at the head. Reference numeral 106 denotes a memory, and each block can be used for work. Reference numeral 104 denotes an ATA (ATAPI) querier section (hereinafter referred to as ATAPI_I / F section), 105 denotes a hard disk (hereinafter referred to as HDD), and 116 denotes a disk I / F. The ATAPI_I / F unit 104 has an interface with the control unit 110 and the memory 106 connected to the bus 103 and an interface with the HDD 105 and the optical disk 120, and accesses the control registers of the HDD 105 and the optical disk from the control unit 110 and the like. Perform the conversion.

  Reference numeral 116 denotes a disk I / F, which has a mechanical deck including a head and a motor, a control circuit that controls them, and an interface that can be connected to the ATAPI_I / F 104, and reads and writes data and the like on the optical disk D. The ATAPI I / F unit 104 is a so-called direct memory access (DMA) that automatically transfers read or write data by designating the head address and data amount on the bus 103 and the head sector of the HDD 105 (or optical disk 120). It has a function. The disc D is loaded into and ejected from the recording / reproducing apparatus 100 by an unillustrated ejecting mechanism.

  On the other hand, the HDD 105 is configured so that a general user cannot easily remove it by such an eject mechanism.

  A decoder 108 sequentially reads digital video data from an address on the bus 103 designated by the control unit 110, converts the digital video data into a video signal and an audio signal, and outputs them. Reference numeral 107 is an audio output terminal, and 109 is a video output terminal. The video output terminal 109 and the audio output terminal 107 are terminals for outputting video signals and audio signals of the NTSC system converted by the decoder unit 108 to the outside, and are connected to a television receiver or the like. An on-screen display (OSD) unit 113 superimposes information such as various setting menus, titles, and times on the video output.

  Reference numeral 111 denotes a display panel, which is disposed on the front surface of the main body or the like and is provided for displaying minimum information. Reference numeral 112 denotes an operation switch group, which is an input unit for the user to perform power-on, HDD and optical disc selection, recording / playback selection, recording mode for determining image quality, and the like. Reference numeral 114 denotes a remote control light receiving unit which receives a signal from the infrared remote control unit R and transmits it as a pulse to the control unit 110, which converts the data into data and recognizes it as a control command. The infrared remote controller R is a user input means like the operation switch group 112, and the description of operating the operation switch group 112 in the following description may basically be an infrared remote controller.

  Reference numeral 115 denotes a real-time clock for transmitting calendar and time information to the control unit 110. The initial value and the count start command are input by the user through the operation switch 112 and given through the control unit 110. For example, the recording reservation function uses time information generated by the real time clock 115. The same applies to the time stamp information given to the recorded content.

  The control unit 110 is equipped with software for handling a predetermined file system, and data is read from and written to the HDD 105 and the optical disc D according to this file system. In addition, from the start to the end of one recording is basically managed as one content. Even when a content list is displayed, this content unit is the basis.

  Next, the recording operation will be described. Here, it is assumed that the HDD 105 is selected as the recording medium.

  First, when the power is turned on, the control unit 110 searches the HDD 105 for a recordable (free) area in accordance with the file system described above. At this time, the recordable capacity is calculated, and the recordable time is calculated from the recordable capacity and the recording mode. Thereafter, during recording, the decrease in recordable capacity is monitored, and the recordable time is periodically updated. On the other hand, the user uses the operation switch group 112 to notify the control unit 110 of an operation for selecting a desired channel. The control unit 110 always detects the state of the switch and monitors the user's operation. Here, the tuning operation is detected, and the tuner unit 101 is controlled to change the channel. Hereinafter, the user's operation is transmitted to the control unit 110 through the operation switch group 112 unless otherwise noted.

  Next, when the user generates a recording start request, the control unit 110 controls each block in order to start recording of the selected broadcast program. First, the encoder 102 starts the encoding process, and controls the digital video data to be accumulated at a predetermined address in the memory 106. Each time a predetermined amount of data is accumulated, the encoder 102 notifies the control unit 110 by means such as an interrupt. The control unit receives this notification and notifies the encoder 102 of the start address to be stored next. Further, the control unit 110 issues a command to the ATAPI_I / F unit 104 to write the digital video data stored in the memory 106 by the encoder 102 to the HDD 105.

  At this time, the area written in the HDD 105 is a recordable (empty) area searched according to the file system. A series of processing from the encoding processing to writing to the HDD 105 is repeated until a recording stop request is generated. Also, management information such as content recording time, recording date / time, channel, title, or information necessary for special playback is added as a file header (or footer), or a content management file is generated in the HDD 105. Record.

  Next, the reproduction operation will be described. Again, the content to be reproduced is selected by the operation of the operation switch group 112 by the user. A sequence in which reproduction is started by displaying a content list or a representative image (thumbnail) associated with the content (hereinafter referred to as a content selection screen), moving the pointer to the desired content, and determining it is common. Alternatively, by directly pressing a playback key (or a key assigned to issue a playback command), for example, the first content, the continuation from the previous playback, the last recorded content, or the like may be played.

  The control unit 110 reads the digital video data of the content determined as described above from the HDD 105. Specifically, a command is issued to the I / F unit 104 so that it is read from the HDD 105 and stored in the memory 106 contrary to the time of recording. At this time, the control unit 110 designates the read head sector of the HDD 105, the write head address of the memory 106, and the data amount in the same manner as in recording. Next, the control unit 110 issues a command to the decoder unit 8 to decode the digital video data stored in the memory 106. A series of processes is repeatedly executed so that the digital video data to be decoded by the decoder unit 108 is not interrupted until a user operation such as the end of content, stop, or pause is applied.

  An example of the content selection screen will be described with reference to FIG. A display screen 201 is output from the video output terminal 109 and displayed on a television receiver or the like. Reference numerals 203 to 208 are representative images of content. Reference numeral 211 denotes a selection frame, which is displayed to inform the user of the selected content. It moves according to the user's operation, moves the selection frame 205 to the desired content, and starts playback. Although not shown in FIG. 2, information such as content recording date, title, and recording mode may be displayed together.

  The recording and reproducing operations described so far are the same when recording and reproducing on the optical disc D. Data can be copied and moved between the HDD 105 and the optical disk D under the control of the control unit 110.

  Next, a recording operation that is a feature of the present invention will be described with reference to the flowchart of FIG.

  When a recording operation is started, such as when the user presses a recording key, it is determined whether the recording medium is the optical disc D or the HDD 105 (S401). If the HDD 105 is selected instead of the disk D, the recording process to the HDD 105 is executed until a recording stop command is generated as described above (S405).

  On the other hand, if the disk D has been selected, recording on the optical disk D is started in the same manner as recording on the HDD 105 (S402). Then, while recording on the disc D, it is determined whether or not the recordable time of the optical disc D is equal to or longer than a predetermined threshold (S403), and if there is a remaining recording, a recording stop command is generated by a user operation It is determined whether or not (S404). When a recording stop request is generated, the control according to this flowchart is terminated.

  Further, when the remaining recording capacity of the disk D becomes smaller than a predetermined threshold, data recording to the HDD 105 is started (S405b). The content of this process is almost the same as in step S405, but here, recording on the optical disc D is stopped after a predetermined time from the start of recording on the HDD 105. In addition, the data recording to the HDD 105 in step S405b is finished when a recording stop command is issued by the user.

  Through the process of S405b, the data immediately before the recording stop on the optical disc D is recorded in common on the HDD 105, and after the recording on the disc D is stopped, the data is continuously recorded on the HDD 105. Hereinafter, this operation is referred to as relay recording. At the time of relay recording, a predetermined section near the switching portion from the disk D to the HDD 105 is recorded on both media. This section is a marginal area.

  In this way, when there is a recording stop instruction after relay recording, the remaining amount of the optical disk D is compared with the amount of data recorded in the HDD 105 relay (S408). The amount of data relay-recorded on the HDD 105 to be compared here is the amount of data excluding the margin from the content newly recorded on the HDD 105 this time.

  If the remaining amount of the disk D is larger than the amount of data relay-recorded on the HDD 105, the data relay-recorded on the HDD 105 is moved to the optical disk D. In other words, the fact that the remaining amount of the disk is larger in S406 indicates that although the relay recording is performed on the HDD 105, the recording to the end is possible even if the recording is continued on the optical disk D. Here, the data relay-recorded on the HDD 105 is moved to the optical disc D and combined as one file.

  However, here, the marginal part is deleted and combined. Combining is to add to the file originally recorded on the optical disc D, and to make the stream divided into two into one file in chronological order. In addition, the management file of the disk D generated thereby is simultaneously updated.

  On the other hand, if the amount of data relay-recorded on the HDD 105 in S406 is larger than the remaining amount of the disk D, relay record management information for managing the content recorded across the optical disk D and the HDD 105 is generated in this way, Recording is performed on the HDD 105 and the disk D (S407). The relay record management information may be described in the content management file described above. The controller 110 must be able to identify a specific content from a plurality of optical discs, that is, a disc on which content related to the relay recording management information is recorded. Therefore, a code for identifying which relay management information is related to the relay-recorded content and is associated with the content management information or content file to be recorded on the optical disc is recorded.

  Here, the relay record management information will be described with reference to FIG.

  FIG. 3 is an example of relay record management information recorded in the HDD 105. Reference numeral 301 denotes HDD content management data, and items such as HDD content ID, recording date and time, start position, recording time, capacity, and the like relate to portions recorded in the HDD. The relay ID is assigned only when there is content recorded in the relay, and is “0” when the content is not relay recorded. The control unit 110 generates and records this relay recording management information for each content file recorded in the HDD 105.

  302 is identification data relating to the relay recording content recorded on the optical disc D (hereinafter referred to as relay recording disc section information). DISC_ID is information given to be unique for each optical disc, and the content ID, recording date / time, recording time, free capacity, etc. are all information relating to the optical disc. The relay recording disk unit information 302 is associated with the relay ID. The control unit 110 generates the relay recording disk unit information 302 for each relay recording content file recorded in the HDD 105, records it in a predetermined area of the HDD 105, and records the same information in the relay recording content recorded in the optical disk D. Record each file.

  In this way, by comparing the relay recording management information recorded on the HDD 105 with the relay recording disk portion information 302 recorded on the optical disc D, the relay recording contents recorded on the optical disc D and the HDD 105 can be associated with each other.

  The DISC_ID is information described by the system when the optical disk D is first inserted into the main body or formatted. If individual IDs are written on all discs according to the standard, or if an identification means such as a wireless ID tag is provided, it may be used.

  Next, message information notifying that the remaining relay-recorded data is recorded on the last content recorded on the optical disc is generated and recorded on the disc D. For example, video data for reproducing a video as shown in FIG. 5 for a predetermined time is recorded. This data is video data that has been compressed by the same method as the compression method by the encoder 102. It is also compressed in advance and stored in ROM as a program in the control unit or recorded in the HDD 105 at the time of manufacture.

  By performing the control of the flowchart of FIG. 4 described so far, relay recording is possible, and even when only the data recorded on the optical disc D is reproduced by another device, the content recorded in the relay exists. I understand that

  Next, the state of the content recorded by the flowchart of FIG. 4 will be described with reference to FIG.

  The horizontal axis of FIG. 6 represents the capacity of video data. Ds to De are the maximum amount of video data that can be recorded on the optical disc D. D1 to De correspond to a remaining amount threshold value for determining whether or not to perform relay recording in step S403, and D2 to De are capacities required to record the video data of FIG. The right direction from Hs represents the state of data recorded on the HDD 105. A, B, C, and D represent the respective flows in FIG. 4, and the images shown on the right side are examples of the video data amount and arrangement. Reference numerals 601 to 609 denote video data to be recorded. Hereinafter, it is described as video data 601. Reference numeral 610 denotes relay record management information.

  In FIG. 6A, since the HDD 105 is selected as the recording medium, data is not recorded on the optical disc D. In B, since recording was stopped while the capacity of the optical disk D remained, relay recording was not performed.

  C is a case where relay recording occurs, and when the video data 603 approaches D1, the process proceeds from step S403 to step S405b, recording to the HDD 105 is started, and video data 606 and 608 are recorded. Further, when the video data 603 reaches D2, recording on the optical disc D is stopped. Further, the data in the section D1 to D2 of the video data 603 and the video data 606 are data recorded at the same time, and are the same as the video stream. Also, the video data 605 is recorded after the end of recording as described above. The video data 605 is the video data described with reference to FIG. Although the video data 606 and 608 are divided into two for explanation, they are actually recorded in the HDD 105 as one content (file).

D is once relay-recorded on the HDD 105, but the data 609 relay-recorded on the HDD 105 is less than the remaining amount of the optical disk D, that is,
(D2-De) ≧ video data 609
Therefore, the video data 609a once relay-recorded in the HDD 105 is moved to the disk D and recorded as the video data 609. As described above, the video data 604 and 609 are recorded as one content. As a result, the B pattern and the capacity are only different. Note that the video data 607 and 609a are deleted from the HDD 105 after the movement.

  Next, processing during playback will be described.

  In the present embodiment, a case will be described in which one of the optical disk D and the HDD 105 is selected, and one of the contents recorded on the selected medium is selected and reproduced.

  First, a reproduction operation when the optical disc D is selected by a user operation will be described with reference to the flowchart of FIG. When one of the contents recorded on the disc D is selected and playback is instructed, it is determined whether or not the content instructed to be played is relay recorded content based on the relay recording management information described above. (S701).

  If the content instructed to be reproduced is content that has been relay-recorded, the relay recording disk portion information recorded in the HDD 105 further indicates whether or not the content corresponding to the content instructed to be reproduced is recorded in the HDD 105. The determination is made by comparing the relay ID 302 and the relay ID of the relay recording management information reproduced from the disk D (S702).

  If the relay recording content corresponding to the HDD 105 is recorded as a result of the determination, the content selected from the optical disc D is first played back (S703). And it is discriminate | determined whether the content recorded on the optical disk D became the end part vicinity (S704). Specifically, in the case of C in FIG. 6, it is determined whether or not the video data 603 has been reproduced up to D1, and the relay recorded in the HDD 105 based on the relay recording disk unit information 302 at the time of reproduction up to D1. Playback of the recorded content is started (S705).

  Then, the video signal output from the video output terminal 109 and the audio output terminal 107 are output during the period in which the data D1 to D2 in the video data 603 of FIG. The audio signal to be played is switched to that obtained from the reproduction data from the HDD 105, and the reproduction of the optical disc D is stopped. At this time, naturally, the message screen shown in FIG. 5 recorded as the data 605 in FIG. 6 is not reproduced.

  Thereafter, the remaining portion of the relay recording content recorded in the HDD 105 is reproduced.

  If it is not relay recording content in S701, or if the relay recording content corresponding to the HDD 105 is not recorded as a result of the determination in S702, it is not relay recording or is not self-recording content and is normally played back. This control is terminated.

  Here, when the content instructed to be reproduced is a relay recording content recorded by another device, that is, when the transition is made from step S702, the message screen of FIG. The Therefore, the user can easily understand that there is a continuation of the content in another device.

  In addition, when the relay recording content recorded on the disc D is played back on the device not equipped with the relay recording function described above, the message screen of FIG. 5 is also displayed, and the user has a continuation. Can be easily recognized.

  Next, the reproduction operation when the HDD 105 is selected will be described with reference to the flowchart of FIG.

  When one of the contents recorded on the HDD 105 is selected and reproduction is instructed, it is determined whether or not the content instructed to reproduce is content recorded by relay based on the above-described relay recording management information. (S801).

  When the content instructed to be reproduced is a content recorded by relay, the relay recording disc portion recorded in the HDD 105 further indicates whether or not the content corresponding to the content instructed to be reproduced is recorded in the optical disc D. The determination is made by comparing the relay ID of the information 302 with the relay ID of the relay recording management information reproduced from the disk D (S802).

  If it is determined that the relay recording content corresponding to the HDD 105 has been recorded, the corresponding relay recording content recorded on the optical disc D is detected based on the relay recording management information of FIG. Is reproduced (S803). And it is discriminate | determined whether the content recorded on the optical disk D became the end part vicinity (S804). Specifically, in the case of C in FIG. 6, it is determined whether or not the video data 603 has been reproduced up to D1, and at the time of reproduction up to D1, reproduction of the relay recording content recorded in the HDD 105 is started (S805). ).

  Then, the video signal output from the video output terminal 109 and the audio output terminal 107 are output during the period in which the data D1 to D2 in the video data 603 of FIG. The audio signal to be played is switched to that obtained from the reproduction data from the HDD 105, and the reproduction of the optical disc D is stopped. At this time, naturally, the message screen shown in FIG. 5 recorded as the data 605 in FIG. 6 is not reproduced.

  Thereafter, the remaining portion of the relay recording content recorded in the HDD 105 is reproduced.

  As described above, when relay recorded content is played back by a device that has performed relay recording (self-recording / playback), the corresponding relay recorded content does not matter whether the optical disc D or the HDD 105 is selected. When recorded on the optical disc D and the HDD 105, the user can continuously view the data relay-recorded from the optical disc D to the HDD only by instructing reproduction.

  As described above, according to the present embodiment, when recording on a removable optical disk, when the backup recording (relay recording) is performed on a built-in large capacity recording medium such as a hard disk due to insufficient capacity, the relay recording recorded on the optical disk is performed. Since the message screen information indicating relay recording is added to the end of the content and recorded, the continuation of the content is recorded even if the relay recorded content recorded on this optical disc is played on another device It becomes possible to know what is recorded in the apparatus.

  In this embodiment, when relay recording is performed, identification information for associating relay recording contents with each other is recorded on the optical disc and the HDD, and at the time of reproduction, the relay recording recorded on the optical disc and the HDD according to the identification information. Since the content is automatically and continuously played back, the user can easily view the content recorded on the HDD simply by selecting and playing back the desired content recorded on the optical disc.

  In this embodiment, when relay recording occurs, recording is performed so that the message screen of FIG. 5 is displayed after the relay recording content of the optical disc is reproduced. However, the present invention is not limited to this, and recording is performed as management information. You may do it. However, in this case, it is necessary to define the meaning of the information in advance so that the compatibility between the devices is maintained.

  Also, instead of video data on the message screen, audio data for notifying that it is relay recording content is encoded and recorded on the optical disc, and this message audio data is reproduced after the relay recording content of the optical disc is reproduced. The structure to do may be sufficient.

  Next, a second embodiment will be described.

  FIG. 9 is a block diagram of the second embodiment. The blocks having the same numbers as those in FIG. An encoder unit 902 receives video data from the tuner 101 under the control of the control unit 110 and sequentially converts it into digital video data of the MPEG (Moving Picture Experts Group) system or the like. In addition, an interface for inputting an audio signal from the decoder 908 described later and a video signal from the OSD unit 913 is provided, and can also be converted into MPEG data. Reference numeral 908 denotes a decoder, which sequentially reads MPEG data from an address on the bus 103 designated by the control unit 110, decodes it, and outputs it. Reference numeral 913 denotes an on-screen display (OSD) unit that superimposes bitmap data on digital video data from the tuner 101. Note that the decoder 908 and the OSD unit 913 are devised so that output to the encoder 902 is possible.

  In the configuration of FIG. 9, it is possible to generate a bitmap screen designated by the control unit 110 from the OSD 913 and output it to the encoder unit 902 so that it can be encoded into MPEG data and recorded on the HDD 105 or the optical disc D. .

  In the first embodiment, the message information screen for relay recording to be recorded on the optical disc D is fixed, but in this embodiment, message information that changes as appropriate can be created.

  Therefore, in this embodiment, the relay record information of FIG. 5 is changed as shown in FIG.

  Reference numeral 1001 denotes a screen generated by the OSD unit 913 under the control of the control unit 110. Further, this is compression-encoded by the encoder 902 and recorded on the optical disc D so as to be finally played back when the relay recording content is played back. Reference numeral 1002 denotes an information message, which is different from FIG. 5 in that a variable character string, that is, a character string “1 hour” is added. The one hour is a recording time recorded in the HDD 105 by relay. That is, in this embodiment, when relay recording to the HDD 105 is completed, the playback time of the relay recording content recorded on the HDD 105 is detected, and a message screen is generated based on this playback time information.

  The “manager” part may be registered in advance in the apparatus and replaced with a character string, for example, the owner's name, nickname, or contact information. Further, an image or sound of an area recorded in the HDD may be used as the background.

  As described above, according to the second embodiment, when the relay-recorded optical disk is reproduced by another device, the user can obtain the remaining portion of information more accurately.

  Next, a third embodiment will be described.

  In this embodiment, when the user selects content to be reproduced from the thumbnail list of each content recorded on the optical disc D or HDD 105, an icon as shown in FIG. 11 is displayed in this embodiment.

  An icon 1120 is displayed in the vicinity of the thumbnail of the corresponding content when the control unit 110 determines that the content is relay-recorded on the thumbnail list display screen. 1101 is an example of a content selection screen in the present embodiment. The icon 1120 displayed on the representative images 205 and 208 visually indicates that this content is relay recording content. The icon 1120 is displayed regardless of whether the HDD 105 or the optical disk D is selected.

  That is, when there is an instruction to display the thumbnail list screen with the HDD 105 selected, a representative image of each content recorded in the HDD 105 is displayed as a list as shown in FIG. 10, and the relay recording content is based on the relay recording management information. An icon 1120 is displayed in the vicinity of the representative image. On the other hand, when there is an instruction to display a thumbnail series screen with the optical disc D selected, similarly, representative images of each content recorded on the optical disc D are displayed as a list as shown in FIG. Based on this, an icon 1120 is displayed in the vicinity of the representative image of the relay recording content.

  By displaying the icon 1120 in this manner, for example, when the HDD 105 is selected, it can be understood that the head portion of this content is not recorded in the HDD 105 if there is no optical disk. It is possible to know before playback that the relay recording content cannot be viewed until the end unless it is self-recording playback. If the optical disk is not self-recording / reproducing, the color and shape of the icon 1120 may be changed.

  As described above, according to the present embodiment, in the case of a device having this function, the user can know whether or not the relay recording is performed when selecting the content, and the disc can be prepared in advance.

  Further, when the first half of the data corresponding to the relay recording content recorded on the HDD is not recorded on the optical disc, the control unit 110 is the content in which the designated content is relay recorded, and the first half of the data is recorded. The OSD unit may be controlled to generate and output a message screen indicating that it is recorded on another optical disc.

  At that time, if the optical disk is not a recorded medium, notification may be made to replace the medium.

  Further, relay recording may not be executed when the recording capacity can be calculated in advance, such as recording reservation, and recording may be performed on the HDD when the capacity of the optical disk is insufficient.

  In the above-described embodiments, the device for recording and reproducing the video and audio data with respect to the optical disc has been described. On the other hand, the present invention can be similarly applied to an apparatus for recording and reproducing video, audio data, and the like, and has the same effect.

  Also, the hardware, software, screen configuration, and design described here are not limited, and it is sufficient that the same function can be realized. For example, software that operates on a personal computer with a built-in tuner and realizes the above functions may be used.
