Description

  The present invention relates to a recording / reproducing apparatus such as a hard disk recorder that performs reservation recording, for example, and more particularly to a recording / reproducing apparatus and a recording / reproducing method for displaying a library screen of recording information in repeated reservation recording such as a continuous drama.

  Recently, recording / reproducing apparatuses such as hard disk recorders are becoming more common with the spread of digital devices, and it becomes easier to access recorded information than in the case of recording / reproducing processing by the previous VTR (Video Tape Recorder). Yes. In such a recording / reproducing apparatus, it is possible to perform reservation recording processing, and automatically perform absence recording by giving a designated day, day of the week, date and time, channel selection information, and the like. Here, in particular, when a large amount of scheduled recording becomes easy in a recording / reproducing apparatus such as a hard disk recorder, video information is recorded as long as the capacity of the hard disk permits, and as a result, a large amount of recording is performed in the storage area. Since the information is full, there is a demand for easy management of recording information. On the other hand, as a method for organizing the management information of the recording information, a title sorting process and the like are known.

In Patent Document 1, in the recording / reproducing apparatus, the management information of such recording information is rearranged based on the attributes of the recording information, for example, the day of the week and the recording start time. It is possible to know how a plurality of recording information such as is recorded continuously.
JP 2001-266457 A.

  In the above-described prior art, a plurality of management information in units of recording information is sorted in the list and the display order is changed to make the screen relatively easy for the user to see. Therefore, for example, if there are 8 recordings of the continuous drama A, 8 rows of the management table are used, and if there are 6 recordings of the continuous drama B, 6 rows of the management table are further used. Therefore, the compression effect of the management table cannot be expected at all. For this reason, there is a problem that it cannot be said that it is a simple display method for a large-volume recording usage environment in which tens to hundreds of contents are handled as the capacity of the hard disk drive increases. Moreover, in a general user's sense, in a situation where there is a large amount of recording information, it is better to recognize the library for each content than to recognize the library for each recording unit. There is a problem that the library function of the device does not support such a recognition method.

  The present invention provides an additional recording mode (continuous mode) etc. when performing scheduled recording processing, and easily displays a large amount of information by displaying recording information in the same mode as a unit when displaying the library screen after recording. An object of the present invention is to provide a recording / reproducing apparatus capable of performing the above.

  A recording / reproducing apparatus according to an embodiment of the present invention is provided with a tuner unit that selects and decodes a broadcast signal and outputs video information, and a recording unit that records the video information of the tuner unit in a recording area. Stores day-of-week information, time information, channel selection information, and continuous mode information that repeatedly performs scheduled recording for these information and handles the recording information as a series of information, and controls the tuner unit and recording unit based on these information When displaying the recording information management information recorded by the continuous mode information as the library information, the image display as a unit of management information even when the recording information is recorded multiple times The recording / reproducing apparatus includes a library generation unit that generates display information as much as possible.

  In the recording / reproducing apparatus described above, when performing scheduled recording, for example, an additional recording mode (continuous mode) is provided as a recording mode for a program that is repeatedly recorded such as a continuous drama or a program broadcast every day. To make a scheduled recording. When the management information after recording is displayed on the library screen, even if the recording information in the additional recording mode (continuous mode) is, for example, 15 times, it can be displayed in one line (one unit) on the library screen. The management information of countless recording information in the hard disk having a large capacity can be compressed without difficulty and displayed very easily.

  Furthermore, by specifying or clicking the management information indicated in this line (one unit) by the user's operation, for example, 15 times of recorded information can be selected along with the display of viewing / unviewing. By displaying in a possible manner, the user can easily perform subsequent operations.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The recording / playback apparatus according to an embodiment of the present invention proposes a “additional recording mode” for recording a video title. The additional recording mode (continuous mode) is a recording mode in which the recorded title is repeatedly added to the recorded title as it is literally, and corresponds to repeated scheduled recording processing such as a continuous drama, for example. It is.

  When considering the usage scene of a video recorder, if recording is repeated weekly as in a drama, the number of titles displayed on the library screen etc. will increase as the number of titles increases every time recording is performed with a conventional video recorder. When checking the situation, it is necessary to refer to many pages, and there is a situation where it becomes very unusable. On the other hand, in the recording / reproducing apparatus according to the embodiment of the present invention, a recording mode called “additional recording mode” is proposed, thereby enabling a very simple library display and easily performing subsequent reproduction processing. be able to. If it is desired to cancel the write-once mode, it is easy to return to the same library display as before by changing the write-once mode to the normal mode when recording reservation.

The optical pickup 51 emits a laser beam corresponding to the drive current from the mounted laser diode 54 and irradiates the storage area of the optical disc D rotated at a predetermined number of revolutions by the disc motor 63, thereby performing a recording process. It is what is said.

(Detailed operation)
Recording Process etc. Next, the operation of the recording / reproducing apparatus 10 having such a configuration will be described in more detail. First, the operation during recording will be described in detail, including other embodiments. As an input side of the recording / reproducing apparatus 10, the network I / F unit 11 connects to the server S or the like via the Internet or the like and downloads content information or the like. The tuner unit 12 selects a broadcast signal via an antenna, demodulates it, and outputs a video signal and an audio signal. The tuner unit 12 corresponds to a wide variety of types, for example, terrestrial analog broadcasting, terrestrial digital It covers broadcasting, BS analog broadcasting, BS digital broadcasting, CS digital broadcasting, etc., but is not limited to this. Also, it is not always necessary to provide only one. For example, it is also preferable that the market has two or three analog broadcast tuners and functions in parallel in accordance with a reservation recording request. It is.

  The input unit 13 receives a luminance signal, a color difference signal, a video signal such as a composite, and an audio signal from the outside. These inputs are controlled by the selector 16 controlled by the control unit 30 and the like, and are selectively supplied to the encoder unit 21. In other words, an external analog video signal and an external analog audio signal from the input unit 13, or an analog video signal and an analog audio signal from the TV tuner 12 are input to the encoder unit 21 via the selector 16.

  The encoder unit 21 includes a video and audio analog-to-digital converter that digitizes an analog video signal and an analog audio signal input by the selector 16, a video encoder, and an audio encoder. Furthermore, a sub-picture encoder is also included. The output of the encoder unit 21 is converted into a predetermined DVD-RAM format by a formatter unit 23 including a buffer memory and supplied to the previous control unit 30.

  The encoder unit 21 can also supply the compressed digital video signal or digital audio signal directly to the formatter unit 23 when a directly compressed digital video signal or digital audio signal is directly input. The encoder unit 21 can also directly supply the digital video signal and audio signal that have been converted from analog to digital to the video mixing unit 24 and the selector unit 17.

  In the video encoder included in the encoder unit 21, the digital video signal is converted into a digital video signal compressed at a variable bit rate based on the MPEG2 or MPEG1 standard. The digital audio signal is converted into a digital audio signal compressed at a fixed bit rate based on the MPEG or AC-3 standard, or a digital audio signal of linear PCM.

  When a sub video signal is input from the input unit 13, or when a DVD video signal having such a data structure is broadcast and received by the TV tuner 12, the sub video signal in the DVD video signal is sub video. It is encoded by the encoder (run-length encoding) to become a sub-picture bitmap.

  The encoded digital video signal, digital audio signal, and sub-picture data are packed by the formatter unit 23 to become a video pack, an audio pack, and a sub-picture pack, and these are assembled to form a DVD-recording standard (for example, DVD -Standards recorded on RAM, DVD-R, DVD-RW, etc.).

  Here, the apparatus of FIG. 1 uses the control unit 30 to send information (packs of video, audio, sub-picture data, etc.) formatted by the formatter unit 23 and the created management information to the hard disk drive unit 18 or the disk drive. It can be supplied to the unit 19 and recorded on the hard disk unit 18 or the optical disc D. Also, information recorded on the hard disk unit 18 or the optical disk D can be recorded on the optical disk D or the hard disk unit 18 via the control unit 30 and the disk drive unit 19.

  Further, according to the above-described reservation recording management unit 42 and library generation unit 43, reservation information input from the remote controller R or the operation unit 32, or an EPG (via the tuner unit 12 or the network I / F unit 11) Scheduled recording is performed based on the electronic program guide) information, and library information corresponding to the recording information accumulated from the reserved recording is generated and managed by the library generation unit 43.

-Editing process etc. Next, the editing process of the recorded information is mainly described in detail including other embodiments. Editing processes such as deleting a part of video objects of a plurality of programs recorded on the hard disk unit 18 or the optical disk D or connecting objects of different programs can be performed.

  The control unit 30 provides an MPU (micro processing unit) or CPU (central processing unit), a ROM in which a control program is written, and a work area necessary for executing the program in order to facilitate editing processing. And a RAM for performing.

  The MPU of the control unit 30 uses the RAM as a work area according to the control program stored in the ROM, determines a read / write address in the hard disk drive unit 19, detects a defect location, detects an unrecorded area, records video It is also preferable to perform information recording position setting, UDF recording, AV address setting, and the like.

  As another embodiment, the control unit 30 includes a directory detection unit, a management information control unit for editing and recording, a VMG (whole video management information) information creation unit, and copy related information (not shown). It is also preferable to include a detection unit, a copy and scrambling information processing unit (RDI processing unit), a packet header processing unit, a sequence header processing unit, an aspect ratio information processing unit, and the like.

  The contents to be notified to the user during the editing process or other processes are displayed on the display unit 31 of the recording / playback apparatus or the OSD (ON Screen display). In addition, the control unit 30 has an operation unit 32 that gives an operation signal for operating this apparatus. It is preferable that the operation unit 32 further includes a remote controller R.

  The timing at which the control unit 30 controls the disk drive unit 19, hard disk drive unit 18, control unit 30, encoder unit 21, and / or decoder unit 22 is time data from an STC (system time clock) (not shown). Can be performed based on. Recording and playback operations are normally executed in synchronization with the time clock from the STC, but other processes may be executed at a timing independent of the STC.

・ Reproduction processing, etc.
Next, the process of reproducing recorded information will be described in detail including other embodiments. The decoder unit 22 separates and extracts each pack from a DVD format signal having a pack structure, a memory used when pack separation or other signal processing is performed, and main video data (video pack) separated by the separator. V decoder that decodes the content), an SP decoder that decodes the sub-video data (sub-picture pack content) separated by the separator, and an A decoder that decodes the audio data (audio pack content) separated by the separator Have In addition, a video processor is provided that appropriately synthesizes the decoded sub-video with the decoded main video, and outputs the menu, highlight button, subtitles, and other sub-videos superimposed on the main video.

  The output video signal of the decoder unit 22 is input to the video mixing unit 24. The video mixing unit 24 synthesizes text data. The video mixing unit 24 is also connected to a line that directly takes in signals from the TV tuner 12 and the input unit 13. The video mixing unit 24 is connected to a frame memory (not shown) used as a buffer. The output of the video mixing unit 24 is supplied to the selector unit 17, and if selected by the selector unit 17, it is supplied to the display 26 for display or supplied to an external device via the I / F (interface) unit 27. Is done.

  The output audio signal of the decoder unit 22 is analog-converted by a digital / analog converter (not shown) via the selector unit 17 and supplied to the speaker 25 or supplied to an external device via the I / F unit 27. The selector unit 17 is controlled by a select signal from the control unit 30. Thus, the selector unit 17 can directly select a signal that has passed through the encoder unit 21 when directly monitoring the digital signal from the TV tuner 12 or the input unit 13.

  The formatter unit 23 of the encoder unit 21 creates segmentation information during recording and periodically sends it to the MPU of the control unit 30 (information at the time of GOP head interrupt, etc.). The segmentation information includes the number of VOBU packs, the end address of the I picture from the beginning of the VOBU, and the playback time of the VOBU.

  At the same time, information from the aspect information processing unit is sent to the MPU at the start of recording, and the MPU creates VOB stream information (STI). Here, the STI stores resolution data, aspect data, and the like, and at the time of reproduction, each decoder unit is initialized based on this information.

  The control unit 30 receives data in VOBU units from the formatter unit 23 of the encoder unit 21 and supplies the data to the disk drive unit 19 or the hard disk drive unit 18. In addition, the MPU of the control unit 30 creates management information necessary for reproducing the recorded data. When the MPU recognizes a data recording end command, it sends the created management information to the control unit 30. Thereby, the management information is recorded on the disc. Accordingly, when encoding is performed, the MPU of the control unit 30 receives data unit information (such as segmentation information) from the encoder unit 21. The MPU of the control unit 30 recognizes management information (file system) read from the optical disk D and the hard disk unit 18 at the start of recording, recognizes an unrecorded area of each disk, and sets the recording area on the data to the control unit. 30 to the optical disc D.

  Further, as will be described later, the control unit 30 accesses the content information server S provided on the Internet, for example, via the network I / F unit 11, downloads the content information, and drives the hard disk drive. It can be recorded in the storage area of the unit 18. In addition, the content information recorded in the storage area of the hard disk drive unit 18 is read from the hard disk drive unit 18 and decoded by the decoder unit 22 in accordance with a user operation, and then via the video mixing unit 24. The signal is appropriately selected by the selector unit 17 and supplied to the external device via the speaker unit 25 and the display 26 or the I / F 27.

  The recording / reproducing apparatus 10 of this embodiment has a comprehensive function as described above, and performs recording / reproducing processing by the hard disk unit 18 (or the optical disc D) for many sources. Next, the broadcast signal reserved recording process using the hard disk unit 18 and the recording information library display process after recording will be described in detail below.

<Reserved recording process and library display process>
2 is an explanatory diagram showing an example of a recording reservation screen of the recording / reproducing apparatus according to the embodiment of the present invention, FIG. 3 is an explanatory diagram showing an example of a library screen (corresponding to the additional recording mode), and FIG. FIG. 5 is an explanatory diagram showing an example of the library screen (not applicable to the additional recording mode: title sort), and FIG. 6 is an explanatory diagram showing an example of the library screen (corresponding to the additional recording mode). FIG. 7 is an explanatory diagram showing an example of the playlist screen (viewed / unviewed display) of the library screen (corresponding to the appending mode), and FIG. FIG. 9 is a flowchart showing an example of display processing of the library screen (corresponding to the additional recording mode), and FIG. Flowchart illustrating a unified function), FIG. 10 is a flowchart showing an example of a reproduction process similarly performed from the library screen (append mode support).

  A recording / reproducing apparatus according to an embodiment of the present invention is a composite recording / reproducing apparatus having a recording function, a reproducing function, an editing function, etc. as described above, and the scheduled recording process is performed in the following procedure. Furthermore, library information corresponding to recording information by reserved recording or the like is generated and used.

Reservation recording processing Reservation recording processing is recorded reservation information based on input information given from the user via the operation unit 32 or the remote controller R, or an EPG (Electronic Program) acquired via the tuner unit 12 or the network I / F unit 11 Guide) is based on information. When the operation unit 32 or the remote controller R is used, the recording date (or every Friday, every day of the week, from Monday to Friday), the broadcast channel, the start time / end time, and “long time / high image quality / standard” And other parameters such as the recording mode such as “normal mode, overwrite mode, additional recording mode” are input. Furthermore, it is also preferable to type a title and other additional information into the user.

  It is also possible to make a recording reservation by displaying a broadcast program guide on a television screen or the like using an EPG acquired via the tuner unit 12 or the network I / F unit 11 and specifying it with a cursor or the like. In this case, additional information such as a title can be easily taken into the storage area of the scheduled recording management unit 42. Here, a recording reservation screen created based on the EPG information acquired via the analog terrestrial tuner included in the tuner unit 12 is shown in FIG. Here, “additional recording mode” (continuous mode), which is one embodiment of the present invention, is set to the recording reservation of the title “white imaginary tower” and the title “brand”.

  This “additional recording mode” (continuous mode) is a recording mode that is used, for example, for reserved recording of a continuous drama or the like, and displays a plurality of pieces of recording information as one unit of management information when creating a library to be described later. That is, this recording mode is used for recording reservations that are repeatedly recorded, for example, every Thursday, 8 channels, and 10: 00 to 11:00 at night.

  In accordance with such recording reservation information, for example, the tuner unit 12 selects and reproduces a desired broadcast signal under the control of the control unit 30 and the reserved recording management time unit 42, and the hard disk driver unit 18 and the like. Are repeatedly recorded in a predetermined storage area.

Library display processing Next, with respect to the recording information that has been reserved recording (including manual recording is possible) as described above, the control unit 30 and the library generation unit 43 operate according to an instruction from the operation unit 32 or the like of the user. The library display process is performed as shown in FIG. That is, when there is a library screen display instruction from the user via the operation unit 32 or the like (S11), under the control of the control unit 30, the library generation unit 43 stores the storage area of the scheduled recording management unit 42 or the hard disk driver. By searching the section 18, the management information of the recording information stored in the storage area such as the current hard disk driver section 18 is collected (S12). Then, for each piece of management information of the recording information, it is determined whether the management information is in the additional recording mode (S13). Here, if the management information is not the recording information recorded in the additional recording mode, all the plurality of management information is arranged in time series order, for example (S17), and corresponds to, for example, a library screen display as shown in FIG. Image information is generated and supplied to, for example, the video mixing unit 24 (S18).

  On the other hand, when the management information indicates that the recording information is recorded in the additional recording mode (S13), the management information of the same date or channel (same title) is regarded as the same information and is converted into continuous recording information. A chapter point is set (S15). Then, the management information regarded as the same information is rearranged in chronological order (S16). Note that these processes may be performed when the scheduled recording starts and ends according to the reservation information, or may be performed when the user instructs display of the library screen. When these processes are completed for all management information (S17), the library generation unit 43 generates image information to display a library screen as shown in FIG. 3 on the display 26 or the like, for example, for example, video mixing. This is supplied to the unit 24.

  Here, the library screen corresponding to the “append mode” (continuous mode) shown in FIG. 3 will be described. In addition to the channel, viewed / not-viewed, date, start / end time, title and image quality The number of recordings is shown. Further, for example, since “additional recording mode” (continuous mode) is set for the title “brand” and the title “white imaginary tower”, there are three recording images or 14 recording images here. Nevertheless, only one unit of management information is displayed. Here, the “number of recordings” indicates that although one unit is displayed for the title “brand” and the title “white imaginary tower”, it has three recorded images or 14 recorded images. It is what.

  By adopting a library screen corresponding to such an “append mode” (continuous mode), the library screen is dramatically shorter and simpler, and it is understood that it is the best display format for the user.

  Also, as an example of the viewing / unviewing display method on the library screen of FIG. 3, if all of the recording information corresponding to one unit of management information has been viewed, the unviewed mark is not displayed, When some of the recorded information corresponding to one unit of management information includes unviewed image information, it is preferable to display an unviewed mark as shown in FIG. It doesn't matter how.

-Effect of library screen display by append mode The effect of the library screen corresponding to this "append mode" (continuous mode) can be understood by comparing it with the following display. That is, FIG. 4 simply shows the management information of the recording information in time series for the library screen that does not correspond to the additional recording mode. Here, the management information of a plurality of programs is shown in a cluttered manner, and the library screen is redundant and difficult to grasp the whole. Here, the length is at least twice that of FIG.

  Next, consider the case where the library screen is sorted and displayed by title name as shown in FIG. In this case, although it is a little easier to see, there is no change in the total number of titles compared to the case of FIG. 4, so a shortening effect cannot be expected. It is done.

  In addition, it is still difficult to see if you want to check such as “Which drama you have not watched?”. Furthermore, from the viewpoint of implementation, since the total number of titles that can be displayed is limited, occupying the title index with the same title is wasteful in display.

  In addition, as a manual editing process by the user, it is possible to combine the recorded data of the same title into one data as in the above-described additional recording mode by editing the playlist, etc. That is, for a light user who uses a video recorder only for broadcasting checks such as dramas, even playlist editing is an annoying operation. Therefore, “library display in the additional recording mode (continuous mode)” which is one embodiment of the present invention is It is considered that the user's merit is great in the sense that it automatically provides a redundant and cumbersome library screen with a simple and ideal management screen with high utility value.

  That is, for example, when a redundant library screen that has been reserved and recorded for 7 to 8 titles per week for about 10 consecutive dramas, etc. is displayed again in the above-mentioned additional recording mode, the screen length Is actually reduced to about 1/10 of the length, and it can be seen how great the effect of the library screen display by the write-once mode according to an embodiment of the present invention is.

・ Mode unification processing Next, for example, when performing scheduled recording of a repetitive program such as a continuous drama, first recording as “normal mode”, for example, four times, and then recording as “additional recording mode” three times Let us consider how to display the library information management information of the recording information. In the case of the flowchart of FIG. 8, the first four times are displayed by four lines, and the latter three times are displayed in the appending mode, so that the library is displayed by one unit, ie, one line.

  Here, in the processing shown in FIG. 9, the management information of the recording information in the normal mode is changed to the management information when recording in the additional recording mode retroactively when the mode is changed to the additional recording mode. That is, display is performed by one line.

  That is, when a library display process is performed as shown in FIG. 9 and there is a library screen display instruction from the user via the operation unit 32 or the like (S11), under the control of the control unit 30, the library generation unit 43 By searching the storage area of the reserved recording management section 42 or the hard disk driver section 18, the management information of the recording information stored in the storage area such as the current hard disk driver section 18 is collected (S12).

  If there is a recording mode inconsistency for the management information of (same title) or the same date (every day, etc.) (S21), the management information of (same title) or the same date (every day, etc.) Then, retroactively, the current recording mode, that is, the additional recording mode is changed and unified (S22). Then, it is determined for each piece of management information of the recording information whether or not the management information is in the write-once mode (S13). Here, if the management information is not the recording information recorded in the additional recording mode, all the plurality of management information is arranged in time series order, for example (S17), and corresponds to, for example, a library screen display as shown in FIG. Image information is generated and supplied to, for example, the video mixing unit 24 (S18).

  On the other hand, when the management information indicates that the recording information is recorded in the additional recording mode (S13), the management information of the same date or channel (same title) is regarded as the same information and is converted into continuous recording information. A chapter point is set (S15). Then, the management information regarded as the same information is rearranged in chronological order (S16). Note that these processes may be performed when the scheduled recording starts and ends according to the reservation information, or may be performed when the user instructs display of the library screen. When these processes are completed for all management information (S17), the library generation unit 43 generates image information to display a library screen as shown in FIG. 3 on the display 26 or the like, for example, for example, video mixing. This is supplied to the unit 24.

Reproduction Process Next, the reproduction process of the recording information in the additional recording mode (continuous mode) in such library display will be described with reference to the flowcharts of FIGS. In the above-described additional recording mode (continuous mode), the recording information that is repeatedly recorded is treated as one continuous recording information in the management information. As shown in FIG. The recording information of “Tower” is stored again in the scheduled recording management section 42 or the library generation section 43 as continuous recording information given chapter points. In other words, here, when newly recorded video information is added to the existing video recording information, at least information on new chapter points, total recording time, address, and viewed / unviewed information is displayed. By adding to the management information, it is considered that the additional writing process has been performed.

  Further, when the library screen of FIG. 3 is displayed on the display 26 or the like, the management information of the postscript mode (continuous mode) is selected by the user's operation, and as shown in (2) of FIG. The viewed data and the unviewed data are displayed so as to be distinguishable from each other.

  Here, with reference to the flowchart of FIG. 10, the reproduction process of the recording information in the additional recording mode (continuous mode) in the library display will be described. When the library screen is displayed (S31), the management information of the additional recording mode from the user is displayed. On the other hand, for example, when a reproduction instruction is given by specifying an area with a cursor or a double click operation with an enter key or the like (S32), the recorded information is recorded from the head of unviewed according to whether the recorded information is viewed or not viewed. Is reproduced (S34). The operation is that a so-called resume point is at the start point of the unviewed chapter.

  If a skip operation is received from the user via the remote controller R or the operation unit 32 during the reproduction, the jump operation jumps to the chapter point designated by the skip operation according to the chapter point shown in FIG. 6 (S36). The recorded information is reproduced from the chapter points thus obtained (S37). If it is not the management information in the write-once mode in step S32, the recorded information may be reproduced from the address corresponding to the management information designated for reproduction as in normal reproduction (S33).

  As described above in detail, according to the recording / reproducing apparatus according to an embodiment of the present invention, a repetitive scheduled recording such as 10:00 every Thursday is performed by newly setting an additional recording mode (continuous mode), and a library At the time of display, for example, recording information for 10 times is also displayed in one unit, so that the library display can be very compressed and displayed concisely. As a result of the future price reduction and capacity increase of hard disks, for example, by using 7 to 8 serial dramas and regular programs every week in a state of scheduled recording, there are several tens of times in the hard disk. Assuming a usage environment in which recording information overflows in units of 100 to 100, it is considered that the simplified library display by the above-described additional recording mode (continuous mode) is indispensable. That is, in such an environment, it is desirable to display a large amount of recorded information in the hard disk in a library on one or several screens as much as possible. Here, for example, management of an additional recording mode (continuous mode) having recording information for about 10 times. Since the information is compressed to about 1/10 and displayed on the library screen, a very compression display effect can be expected.

  In the above-described embodiment, the recording / reproducing apparatus as a multifunction peripheral including the disk driver unit of the optical disk has been described. However, the present invention is not limited to this. For example, the recording only handles the hard disk driver unit. It goes without saying that the playback apparatus can perform the same processing.
