Description

  The present invention relates to a recording / reproducing apparatus, and more particularly to an improvement in recording control of a recording / reproducing apparatus provided with a plurality of recording medium driving devices in a casing.

  In order to meet the demands of the multimedia era, recent recording / playback devices include a DVD device using a DVD (Digital Versatile Disk) as a storage medium for large-capacity data and a large-capacity and inexpensive hard disk drive (HDD). It is common to have.

  The DVD device uses a red semiconductor laser with a wavelength of 6.50 nm as a pickup for the optical disk. A typical DVD has a storage capacity of 4.7 GB.

  On the other hand, Blu-ray Disc (registered trademark) and HD DVD (High Definition DVD) have been announced as optical discs having an increased recording capacity as compared with the prior art. Hereinafter, the Blu-ray disc is referred to as “BD”. In the case of BD, three types of recording capacity of single-sided single layer are standardized: 23.3 gigabytes (GB), 25 GB, and 27 GB. In the case of HD DVD, the recording capacity of single-sided single layer is 15 GB. The specification of 20 GB is also being studied. The recording capacity of these optical discs surpasses that of a DVD with a recording capacity of 8.5 GB for single-sided dual-layer recording. With a BD, a digital high-definition broadcast program lasting more than 2 hours can be recorded on a single disc. Can be recorded. Recording apparatuses using these optical discs are configured to use blue semiconductor laser light having a wavelength of 400 nm for recording and reproducing information (see, for example, Patent Document 1).

  In addition to the existing compact disc (CD) and DVD, in order to support BD, a laser light source of three wavelengths of short wavelength (BD) in addition to long wavelength (for CD) and medium wavelength (for DVD) Has been proposed (see, for example, Patent Document 2). In this apparatus, pickups corresponding to the above three types of wavelengths are provided to save space by using a single drive.

  Patent Document 3 describes a twin-deck type audio device for reproducing and recording a disc, and a two-tray type device having a reproduction-only deck and a recording-only deck.

  In recording AV data on such a recording medium, recording is generally performed by user operation or automatically selecting one of several recording modes having different bit rates and frame rates. Can be done. For example, three types of recording modes in an AV data recording apparatus are defined: fine mode, normal mode, and portable mode in descending order of bit rate and frame rate.

  The user can use these recording modes depending on the content of AV data to be recorded. For example, contents such as movies and dramas are recorded in the fine mode because the user desires to view the images with high image quality, and contents such as news and sports broadcasts are recorded in the normal mode where the image quality is slightly lowered. The portable mode is a content recording mode mainly for viewing on a portable terminal. As described above, the limited recording capacity of the recording medium can be efficiently used by properly using the recording mode according to the target data to be recorded.

  In the portable video recording device described in Patent Document 4, when the input audio and video data is encoded and stored in a memory card, the parameter setting device causes the video content, the image size, and the image resolution to be recorded. The average frame rate and bit rate are set within an optimum range, and the frame rate or frame image quality is dynamically changed during encoding to keep the overall bit rate constant. 2 and 3 of Patent Document 4 show a table configuration of a database that stores video content to be recorded, an image size and an image resolution, and a range of a frame rate and a bit rate corresponding thereto.

  In addition, when the remaining capacity of the recording medium decreases, the user may consider recording all of the content that he / she wants to record on the recording medium even if the image quality is lowered. For example, when the remaining capacity of the recording medium is 1 GB, it is impossible to record 60 minutes of AV data in the fine mode, but it is possible to record in the normal mode.

  In the information recording / reproducing apparatus and the information recording / reproducing method described in Patent Document 5, when it is determined that the recording capacity of the disc has become equal to or less than the specified value, the user sets the recompression setting flag or the recompression order setting flag so that the user can The contents that should be stored with high image quality and the contents that may be stored with low image quality are distinguished from each other, and recompression and rerecording processing according to the contents of the recording data can be performed.

  However, although there is a recording / reproducing apparatus provided with two or more disk devices, there is no description regarding the recording operation of the high-definition signal, for example, for a device provided with a BD, and between one drive when one of the twin drives is a BD device. There is no description regarding bidirectional dubbing control and automatic recording control.

In particular, in DVD and BD, for example, even when the user turns on the power of the device to be used and starts recording, it takes about 15 to 20 seconds until signal writing is actually started on the disk recording medium. However, once the disc recording medium is mistakenly taken out, it takes twice as much time to complete the preparation for recording again, and improvement in operability for the user has been desired.
For this reason, in a device having a plurality of recording or reproducing units in one recording / reproducing device, the current operating state of each recording or reproducing unit can be recognized at a glance, and the operability of the recording or reproducing unit is improved. A recording / reproducing apparatus equipped with display means has been desired.

  The present invention has been made in view of such problems, and an object of the present invention is to improve usability with respect to recording of a recording / reproducing apparatus including an optical disc apparatus including a BD.

  The recording / reproducing apparatus of the present invention is a recording / reproducing apparatus comprising a plurality of recording / reproducing units that record or reproduce information on a plurality of recording media, and a control unit that controls the plurality of recording / reproducing units, A high-definition signal detection unit that detects a high-definition signal; and a setting unit that preliminarily sets whether to record the high-definition signal with respect to any one of the plurality of recording media, and the control unit includes: When the high-definition signal is detected by the high-definition signal detection unit, the recording / reproducing unit of the recording medium set by the setting unit is controlled to perform recording.

  The recording / reproducing apparatus of the present invention includes a plurality of recording / reproducing units for recording / reproducing information on / from a plurality of recording media including first and second recording media capable of recording a high-definition signal, and the plurality of recordings A recording / reproducing apparatus including a control unit for controlling a reproducing unit, the high-definition signal detecting unit for detecting a high-definition signal, and the high-definition signal for any one of the first and second recording media And a setting unit that sets in advance whether recording is performed with priority, and when the high-definition signal is detected by the high-definition signal detection unit, the control unit has a recording / playback unit for the recording medium set by the setting unit. It is characterized by controlling to perform recording.

  More preferably, when recording by the recording / reproducing unit of the first recording medium cannot be performed, the control unit switches to recording by the recording / reproducing unit of the second recording medium and continuously records.

  More preferably, when recording by the recording / reproducing unit of the first recording medium cannot be performed, the control unit switches to recording by the recording / reproducing unit of the second recording medium and continuously records the recording. When recording by the recording / reproducing unit of the medium becomes possible, the continuous recording information recorded on the second recording medium is controlled to be written back to the first recording medium.

  When the recording / reproducing unit of the first recording medium cannot record the high-definition signal, the control unit down-converts the signal to a lower definition signal than the high-definition signal and continuously records it on a recordable recording medium. It may be.

  Further, as a specific aspect, a remaining capacity detection unit that detects a storable capacity of a recording medium that performs recording is provided, and the control unit lacks the remaining capacity of the recording medium detected by the remaining capacity detection unit. If it is, it is determined that the recording is not possible.

  Further, as a specific aspect, a remaining capacity detecting unit that detects a storable capacity of a recording medium to be recorded is provided, and the control unit should record the remaining capacity of the recording medium detected by the remaining capacity detecting unit. From the amount of information, it is determined whether or not the entire volume can be recorded in high-definition on the recording medium on which the recording is performed.If high-definition recording is impossible, down-conversion to a signal with a lower definition than the high-definition signal Record by high-definition and down-conversion.

  As a more preferable specific mode, switching from high-definition to down-conversion is performed at the time of CM or at the time of scene change or at least one broadcast signal change among stereo broadcast and monaural broadcast.

  As a specific aspect, the plurality of recording media include a combination of at least one of an HDD, an optical disk having a recording capacity of 8.6 gigabytes or more on one side, a DVD, a semiconductor memory, or an apparatus conforming to the IEEE 1394 standard.

  As a specific aspect, the first and second recording media are HDDs or optical disks having a single-side recording capacity of 8.6 gigabytes or more.

  It is more preferable that a notification unit that notifies the control by the control unit is provided.

  As described above, according to the recording medium recording / reproducing apparatus of the present invention, when the BD automatic recording mode is set, the recording data is preferentially recorded on the BD side in high definition. Since the high-definition signal is automatically recorded on the BD from the beginning, it is possible to save time and time for the user to transfer or move (move) the image data from the HDD to the BD later. Also, when there is no BD disc or when there is no remaining capacity on the BD, down-conversion recording is automatically performed on the DVD or BD.

  In addition, when automatically recording a high-definition signal of a broadcast signal on a BD, the BD disc is continuously recorded when the BD disc is full, the BD disc is replaced during recording on the HDD, and the high-definition signal continuously recorded on the HDD is recorded on the BD disc. Can be automatically forwarded back to

  Furthermore, when the high-definition signal of the broadcast signal is automatically recorded on the BD, the remaining capacity of the BD disc is detected, and when the entire BD disc does not fit, the entire volume is recorded on a single BD disc. Can be recorded on one BD disc.

  In this way, a usage method that makes use of the characteristics of a recorder equipped with a three-drive integrated HDD, BD, and DVD capable of recording a high-definition signal can be realized, and usability can be greatly improved.

  Hereinafter, preferred embodiments of a recording / reproducing apparatus of the present invention will be described in detail with reference to the accompanying drawings.

  In this specification, the optical disc includes, for example, a read-only CD-ROM, a DVD-ROM, a playable / recordable CD-R (W), a DVD-R (RW), and a BD. The optical disk device refers to a drive device that can drive these media.

First Embodiment FIG. 1 is a perspective view showing an external configuration example of a recording / reproducing apparatus according to a first embodiment of the present invention, and shows a state in which a front panel is closed. FIG. 2 is a view corresponding to the perspective view of FIG. 1 and showing a state in which the front panel is opened. FIG. 3 is a diagram showing an arrangement example of the disk device arranged inside the recording / reproducing apparatus according to the present embodiment. FIG. 4 is a diagram showing a configuration example of a remote control device (hereinafter referred to as “remote control device”) capable of remotely operating the recording / reproducing device. FIG. 5 is a functional block diagram showing an internal configuration example of the recording / reproducing apparatus according to the present embodiment.

  As shown in FIG. 1 to FIG. 3, the recording / reproducing apparatus A according to the present embodiment is different from the DVD apparatus 31 that is the first optical disk apparatus in that the second standard is different from the DVD apparatus in terms of storage capacity. This is a so-called two-tray type recording / reproducing apparatus in which a BD device 35, which is an optical disk device, is disposed adjacently.

  As shown in FIG. 3, the recording / reproducing apparatus according to the present embodiment has a DVD apparatus 31 on the left side and a BD apparatus 35 on the right side when viewed from the front when the general horizontal arrangement is used. A hard disk device (HDD) 33 is disposed below the DVD device 31. The optical disk devices 31 and 35 having a certain thickness are arranged on the left and right sides, and the HDD device 33 that can be made smaller and thinner than the optical disk device is arranged below the DVD device 31 so that the thickness of the housing 1 is increased. The thickness can be reduced. Further, since the finer processing is performed than the DVD disk, high positional accuracy between the pickup and the disk is required (that is, vibration resistance is required), and the HDD device 33 can be a vibration generation source. By arranging the BD device 35 in the horizontal direction and the HDD device 33 below the DVD device 31, the influence of vibration caused by the HDD 33 can be minimized. These disk devices 31, 33, and 35 can all be stored and played back, but include, for example, the case where a DVD device is dedicated to playback.

  In general, the hard disk device 33 has a practical storage capacity of about 400 GB (gigabytes), and can have the largest storage capacity among the three disk devices, and then the BD device 35 and the DVD. The storage capacity decreases in the order of the device 31. Therefore, the HDD device 33 is used as a basic storage device as a data server, and the content is appropriately transferred from the HDD device 33 to the BD device 35 or the DVD device in consideration of the usage status or the required image quality, the occupied storage capacity of the content, and the like. The discs can be distributed to DVD discs or BD discs 31 and stored in a storage medium semi-permanently. The content stored in these storage media can be played back by another playback device, or the original content can be created and distributed.

  As shown in FIG. 1, the recording / reproducing apparatus A according to the present embodiment includes a housing 1 on which an upper plate 1a is disposed, and an openable front panel 25a provided on the front surface when placed horizontally. . On the left and right of the front panel 25a are an RC light receiving unit 17 for receiving a command by an infrared ray from a power on / off switch 1b and a remote control device (hereinafter referred to as "remote control device") shown in FIG. A panel opening switch 25b for opening 25a and a front panel locking mechanism 25 for locking the front panel 25a are provided.

  Although a detailed description of the front panel lock mechanism 25 is omitted, the front panel 25a is normally locked, and the panel open switch of the remote control (the tray open / close switch in FIG. 4B also has this function) or the panel By turning on the opening switch 25b, the front panel 25a is pushed in the opening direction.

  Once the front panel 25a is pushed, the front panel 25a is rotated by the weight of the front panel 25a in the opening direction until the internal angle formed by the front of the housing and the front panel 25a is about 90 degrees, as shown in FIG. The rotation stops when the angle between the front of the body and the front panel 25a reaches about 90 degrees. Note that the front panel 25a can be opened by an operation from the remote control device by releasing the lock mechanism of the front panel 25a by the remote control device. A display unit 40 is provided on the front panel 25a. The display unit 40 includes a substantially circular first display unit 41, second display units 43 and 45, and a third display unit arranged with a certain interval in the horizontal direction when the housing 1 is placed horizontally. 47 are provided.

  As shown in FIG. 2, when the front panel 25a is opened, the first built in the recording / reproducing apparatus A is on the front side of the housing 1 and on the back side when the front panel 25a is closed. The front portions 31a and 35a of the trays of the DVD device 31 that is the optical disc device and the BD device 35 that is the second optical disc device appear. Open / close switches 31b and 35b are provided for loading and unloading the trays for loading the disks of the optical disk devices 31 and 35, respectively. By pushing the open / close switches 31b and 35b, trays for loading DVD disks or BD disks (not shown) corresponding to the respective optical disk apparatuses 31 and 35 are moved forward and backward.

  Below the area where the DVD device 31 and the BD device 35 are arranged side by side, for example, an IEEE 1394 terminal (DV terminal) and a slot 21 for a B-CAS card are provided. The B-CAS card is a card necessary for receiving various broadcasting services such as terrestrial digital television broadcasting, BS digital broadcasting, and 110-degree CS digital broadcasting, and is also used for copyright protection of digital broadcasting programs and the like. . For example, in order to use a broadcast service such as a digital broadcast free broadcast, pay broadcast, pay-per-view broadcast, NHK, automatic display message, and data broadcast interactive service, the slot 21 for the B-CAS card is used. It is necessary to insert a B-CAS card. Reference numeral 21a denotes a push button for taking out the B-CAS card inserted in the B-CAS card slot.

  When the B-CAS card is inserted into the B-CAS card slot 21 with the front panel 25a opened, the front panel 25a is closed by inserting it into the slot until the card is normally locked. In addition, the B-CAS card is prevented from being damaged by the collision of the front panel 25a and the edge of the B-CAS card.

  As described above, each adopts a two-tray system including a DVD device having a disk drive unit and a BD device, and also includes a built-in hard disk device. The delay due to the associated start-up time can be minimized. For example, when a DVD disc or BD disc is newly inserted into the DVD device 31 or the BD device 35, the information of the disc placed in each device is read, and the type of disc, Detect standards, etc. That is, it is possible to shift to the next process (actual reproduction or recording process) only after determining whether or not the disk can be operated for reproduction or recording by the disk device. By using the two-tray method, for example, by inserting two types of discs with different standards into a disc device that matches the standards, the information reading time of different discs is read in parallel, so that the disc device can be read in a short time. Can be started. That is, there is an advantage that the delay caused by reading the information on the disc when the two discs are loaded / unloaded can be reduced by performing the information reading on the two discs in parallel.

  In addition, a so-called dubbing process in which the playback side and recording side disks are fixed and the content recorded on one disk is played back and the played back content is recorded in real time on the other disk does not go through the hard disk device. Is possible. Therefore, it is also possible to record another process in which the hard disk device is in a free state during the dubbing process, for example, a program currently being broadcast on the hard disk device.

  Next, an internal configuration example of the recording / reproducing apparatus A according to the present embodiment will be described with reference to the overall functional block diagram of FIG. 5 and FIG. The description will be made with reference to FIGS. As shown in FIG. 5, the recording / reproducing apparatus A according to the present embodiment executes a CPU 3 (high-definition signal detection unit, remaining capacity detection unit, setting unit, control unit) that performs overall control and functions described later. And a functional block group. As described above, the DVD device 31, the hard disk device 33, and the BD device 35 are provided as blocks having a recording / reproducing function.

  Each of these disk devices 31, 33, and 35 operates based on a control command from the CPU 3 via the disk drive control unit 37 or directly. Actually, in the case of the remote control device RC, an infrared signal is received by the RC light receiving unit 17 by operating each operation button of the remote control device shown in FIG. Then, a signal corresponding to the operation is received and transmitted to the CPU 3. The CPU 3 outputs a command signal for instructing each functional block so as to perform an operation based on the above operation based on the received signal. For example, when the CS broadcast selection button 70d is pressed in the broadcast selection unit 70 of the remote control device RC and the BD selection button 71c is pressed in the target device selection unit, the CS broadcast is transmitted to the BD disc in the BD disc drive device 35. Program content can be recorded. Since a BD disc can store a larger amount of data than a DVD disc, for example, a CS broadcast of 2 to 3 hours or more can be recorded with high image quality.

  When recording, for example, when recording CS or BS digital broadcast, the image / audio signal processing unit 5 including a recording encoder / decoder records, for example, a video signal / audio signal from a CS broadcast program on a BD disc. For example, the signal recorded in the BD device 35 is converted into a format that can be displayed on the display monitor. At this time, the operating status of the BD device 35 is sent to the CPU 3. Thus, the CPU 3 can appropriately monitor the operation status of each disk device and give an appropriate instruction.

  Further, the recording / reproducing apparatus A according to the present embodiment is associated with the CPU 3, and includes a ROM 7 for storing a program for causing the CPU 3 to execute various processes to be described later, and a RAM 11 for developing the program data at a high speed. Broadcast signals from the antenna, content signals and D images obtained when the disk device is driven are output to a display monitor such as a liquid crystal TV, or connected to a DV camera (Institute of Institute) Electrical and Electronics Engineers) 1394 terminal (DV terminal), a LAN terminal connected to the Internet and the like, and an interface unit 15 for controlling input / output of various signals.

  Furthermore, the RC light receiving unit 17 described above, the B-CAS card slot 21, the cooling fan 23 for enhancing the heat dissipation effect, and the front panel driving unit 25 for opening and closing the front panel 25a are provided for opening and closing the front panel. It has a front panel drive unit 25 including a detection unit (not shown) that detects a state, and an input unit 61 that receives various input operations. In addition, the disk device drive control unit 37 and the display unit 40 provided on the front panel 25a are arranged at a certain interval in the horizontal direction when the housing 1 is placed horizontally as described above. The first display unit 41 having a substantially circular shape symbolizing the optical disk and the hard disk, the second display units 43 and 45, and the third display unit 47 are provided. The CPU 3 controls the display control unit 51. The display is controlled via.

  Similarly, the selection switches that also serve as the fourth to sixth display units 48 a to 48 c described above are subjected to display control by the CPU 3 via the display control unit 51. Further, each disk device is provided with detection units 31c and 35c for detecting the presence / absence of a disk, a driving state, and the like. 35c is sent to the CPU 3 via the disk drive control unit 37.

  The CPU 3 controls the operation of each functional unit of the recording / reproducing apparatus A and data communication between the functional units. Specifically, the CPU 3 can execute the necessary control, calculation, and processing of each drive in the recording / reproducing apparatus A by using as a working memory of the RAM 11 in accordance with an operation program stored in the ROM 7 or the like. As a specific operation of the present embodiment, the CPU 3 sets in advance whether to record the high-definition signal on a high-definition signal detection unit that detects a high-definition signal and on which recording medium, BD or HDD. It has a function as a setting unit and a control unit that controls the drive 31, 33, 35 of the set recording medium to perform recording when a high-vision signal is detected. These functions are realized by an automatic recording control process described later.

  Further, an OSD (On Screen Display) function unit 27 is connected to the CPU 3 to display information such as channel, time, and volume, and a message such as BD automatic recording mode setting / confirmation on a screen of a television or the like. The OSD data is not an image, but is stored in a format called a bitmap. This bitmap is converted into YUV format pixel values represented by Y, Cb, and Cr, and the converted pixels are used for television broadcasting or the like. Is superimposed on the original image.

  Hereinafter, the operation of the recording / reproducing apparatus A configured as described above will be described.

  The recording / reproducing apparatus A according to the present embodiment is a recorder equipped with a three-drive integrated type of HDD, BD, and DVD, and has the following basic features (1) to (3).

(1) A recorder with a built-in HDD, BD, and DVD drive. It can record and play back digital broadcasts on HDDs and BDs with high-definition HDTV. Record and play back.
(2) By mounting a BD / DVD twin tray, 6-direction free dubbing and simultaneous recording / playback are possible between (HDD, BD, DVD).
(3) The next-generation digital interface “HDMI output terminal” allows digital broadcasts to be recorded digitally and output to the monitor as it is during playback. High sound quality can be achieved.

  The above (1) to (3) will be described more specifically.

(1) Three drive integrated type of HDD, BD, and DVD When the hard disk device 33 shown in FIG. 5 is configured to have a hard disk capacity of, for example, 160 GB, digital high-definition broadcasting is recorded for about 13 hours with the same high image quality. Is possible. This is an approximate time when BS digital broadcasting (2 Mbps) is recorded.

  In addition, the recording / reproducing apparatus A can be mounted (internal / external) with a terrestrial digital, BS / 110 degree CS digital tuner. When equipped with digital terrestrial and BS 110-degree CS digital high-definition tuners, it can be used as a tuner for digital broadcasting, as well as for digital broadcasting EPG (Electrical Program Guide). Recording and recording reservation can be made.

(2) Mounting of BD / DVD twin tray Three HDD, BD and DVD drives are provided, and six-way mutual dubbing is possible between three media (HDD, BD, DVD).

  FIG. 6 is a diagram for explaining the six-way mutual dubbing of the recording / reproducing apparatus A. In the figure, the direction of the arrow indicates the direction (A to L) of the dubbing between the drive and the interface, and the thickness of the arrow is the order in which the usage scene is large and the importance or requirement is high (thick arrow, thin arrow). , The use scene or the importance level is high in the order of broken-line arrows). Further, the use scene or the importance level is also indicated by a mark (図, ○, Δ in order of importance) in FIG.

  Figure 6a. As shown in FIG. 5, the main dubbing direction A is when high-definition video recording is performed on the HDD and the image quality is left as it is on the BD. In this case, BD is the final storage destination. It is also possible to simultaneously record on the BD while recording high-definition on the HDD.

  In addition, FIG. As shown in FIG. 6, by installing three drives, six-direction dubbing of HDD → BD, HDD → DVD, BD → HDD, BD → DVD, DVD → HDD, DVD → BD has become possible for the first time. As a result, a series drama recorded on multiple DVDs can be saved as a single BD and saved in a space-saving manner, or a program recorded on a BD can be dubbed to a highly compatible DVD-RW or DVD-R for friends. It can be used according to the purpose, such as handing it over. In addition, simultaneous recording and playback such as watching DVD movie software while recording a high-definition program on a BD is also possible. Note that programs that can be recorded only once are BD / DVD / i. It is possible to move to a LINK device. i. A LINK device refers to a device that conforms to the IEEE 1394 standard.

  Here, the case of 1 tray and the case of 2 trays are compared and described. First, in the case of one tray, bidirectional dubbing between HDD and DVD and between HDD and BD is possible, and a total of four data movement paths can be considered. On the other hand, in the case of two trays, as shown in FIG. 6, there are a total of six types of HDD-DVD (B, G), HDD-BD (A, D), and DVD-BD (E, H). Dubbing is possible and high in convenience, and in the case of two trays, the other optical disk can be inserted / removed while one optical disk is being accessed. In addition to DVD-BD dubbing, DVD and BD can be recorded simultaneously. For example, video can be recorded on a DVD with SD image quality via a downconverter, and the same program (can be one tuner) or different programs (in the case of two tuners) or HD image can be recorded on a BD. . As a result, the processing time can be shortened. At this time, there is an advantage that data can be recorded on the HDD at the same time.

  In the case of two tuners, it is possible to perform chasing playback between DVD and HDD while recording video on BD. For example, as chasing playback during dubbing, it is also possible to record this content on a DVD while reproducing and displaying the content of the BD. Furthermore, the DVD can also be chased and reproduced during dubbing from the DVD to the BD. For example, it is possible to record a broadcast program selected by a tuner on a DVD while reproducing a video recorded on a BD.

(3) Equipped with HDMI output terminal Equipped with a next-generation digital interface “HDMI output terminal” that can transmit digital high-definition program video and 5.1ch audio recorded and played back as-is with digital signals. Not only high-definition video but also 525i DVD video images can be up-converted to 1125i / 750p and output. High-definition image quality and high-quality sound of digital broadcasting can be realized simply by connecting to the HDMI terminal with an HDMI terminal compatible device with one HDMI cable.

  The above are the basic features (1) to (3) of the three-drive integrated recording / reproducing apparatus A for HDD, BD, and DVD, but also have the following features (4) to (13).

(4) Output of recorded program The program recorded on the HDD of the recording / reproducing apparatus A is i. It can be dubbed to a D-VHS video deck or AV-HDD connected by a LINK cable. Programs that can be recorded only once in digital broadcasting can be stored on other media by the move.

(5) i. LINK input recording A program recorded on the D-VHS can be recorded on the HDD of the recording / reproducing apparatus A, and the contents of the recorded D-VHS tape can be edited on the HDD. It can be saved on a BD to save space.

(6) Control from other device The recording / reproducing apparatus A from the other device, i. It is possible to control via LINK. For example, i. It is possible to control the recording / reproducing apparatus A from a LINK device or move (move) a high-definition program recorded on the HDD by another digital high-definition recorder to the HDD of the recording / reproducing apparatus A.

(7) "DV input" capable of high-quality dubbing from a DVC camera
i. High-quality digital dubbing is possible by connecting to a DV digital video camera via LINK. Operations such as playback / stop / fast forward / rewind of the video camera can also be performed by the remote control device RC (see FIG. 4).

(8) High-speed dubbing from HDD to BD It is possible to perform high-speed dubbing (when recording in the EP mode) to a BD at a maximum speed of approx.

(9) Time-shift viewing While viewing a high-definition program, automatic recording is possible at any time (selected from 30 minutes / 60 minutes / 90 minutes). You can pause the program you are watching or go back and review it.

(10) Chasing playback Even when recording a high-definition program, the recorded program can be viewed from the beginning with the same high-definition image quality without waiting for the end of the recording.

(11) High-definition program editing Supports editing of high-definition programs recorded on a hard disk or BD that require a large amount of data and high-speed processing. Unnecessary scenes can be cut by chapter or partial erasure. As a result, only necessary scenes can be dubbed after editing.

(12) "DVD super multi playback" that can play a wide range of DVD discs
In addition to DVD-RW / -R / + RW / + R, DVD-RAM playback is also supported. You can watch DVD discs borrowed from friends without worrying about the format.

(13) Various recording modes The HDD and BD are provided with a manual mode in which the image quality can be selected from 13 stages including an AUTO mode that can record the image quality of digital broadcasting as it is, and a high-quality SXP mode that exceeds DVD. In DVD-RW / -R, the recording mode can be selected from 32 stages, and the recording mode can be selected according to the disk capacity and the program content.

  In the recording / reproducing apparatus A of the present embodiment configured as described above, AV data can be recorded on HDD, BD and DVD (generally referred to as “recording”). The recording mode includes an automatic recording mode and a manual recording mode, and the user can select the recording mode.

  FIG. 7 is a diagram showing a recording mode and recording time for recording AV data in the three drives of HDD, BD and DVD of the recording / reproducing apparatus A, and shows a recording mode selected by a recording mode button of the remote controller RC.

  The HDD recording in FIG. 7A and the BD recording in FIG. 7B are provided with an AUTO mode in which the image quality of digital broadcasting can be recorded as it is, and a high-quality SXP mode that exceeds DVD. 7A to 7C, the HDD, BD, and DVD have a high image quality (XP) mode, a standard (SP) mode, a long time double (LP) mode, and a long time triple (EP) mode. Prepare. The user can select any one (or a plurality of) of HDD, BD, and DVD according to the disc capacity and program content, and can select the recording mode shown in FIG. 7 for each of HDD, BD, and DVD. .

  FIGS. 8 and 9 are diagrams showing a manual recording mode and recording time for recording AV data on the three HDD, BD, and DVD drives of the recording / reproducing apparatus A. FIG. 8A shows HDD recording, and FIG. B) shows BD recording, FIG. 9C shows DVD-RW (VR format) recording, and FIG. 9D shows DVD-RW (video format) / DVD-R recording.

  When the user selects the manual mode with the manual mode button of the remote controller RC, the image quality can be selected from 32 levels. 8 and 9, the recording mode in which the image quality changes greatly is indicated by a bold line. In the manual recording mode, VBR (Variable bit rate) that changes the data amount to be recorded in accordance with the data amount of the video to be recorded is adopted, so that the recordable time varies depending on the video to be recorded. The image quality stage in the manual mode is an example and is not limited to this.

  Next, the recording operation of the recording / reproducing apparatus A will be described.

  FIG. 10 is a flowchart showing the BD automatic recording operation of the recording / reproducing apparatus A, which is executed by the CPU 3 of FIG. In the figure, S indicates each step of the flow.

  First, in step S1, it is determined whether or not the BD automatic recording mode is set. The BD automatic recording mode is a mode for automatically recording a high-definition signal on a BD, and can be realized for the first time by a recording / reproducing apparatus A having three drives of HDD, BD and DVD. Details of the BD automatic recording mode setting will be described later with reference to FIG. When not in the BD automatic recording mode, the recording data is recorded on the HDD in high-definition in step S10, and this flow is finished. If it is in the BD automatic recording mode, it is determined in step S2 whether or not the BD automatic recording condition is satisfied. The BD automatic recording condition is a condition for determining whether the current recording / reproducing apparatus A is in a device state capable of high-definition recording. For example, whether the broadcast signal is a high-definition signal or whether a BD disc (hereinafter simply referred to as BD) is in the tray. If the BD automatic recording condition is satisfied, the remaining capacity of the BD inserted in the tray is detected in step S3, and it is determined in step S4 whether or not all scheduled recordings are included in this BD. When all of the scheduled recordings are incorporated into the BD, it is determined in step S6 whether or not the scheduled recording is finished, the BD recording is continued until the scheduled recording is completed, and this flow is ended when the scheduled recording is completed.

  If the BD automatic recording condition is not satisfied in step S2, it is determined in step S7 whether or not down conversion is to be performed. If down conversion is to be performed, a down conversion process is performed in step S8, and this flow is terminated. Details of this down-conversion process will be described later with reference to FIGS. When down-conversion is not performed, the flag is set to “1” in step S9 and the process proceeds to step S10. This flag indicates that data to be recorded in the high-definition is not recorded on the BD and is not down-converted. Although described here as a flag, when there are a plurality of reserved recordings, these are status flags indicating the presence or absence of data to be recorded.

  In step S10, the recording data is recorded on the HDD in high definition, and this flow ends.

  By executing this flow, it is possible to record a digital broadcast on the HDD or BD with high definition. In particular, when the BD automatic recording mode is set, the recording data is recorded with priority on the BD side in high definition. Thereby, the high vision signal is automatically recorded on the BD without any special operation by the user. Since the high-definition signal is automatically recorded on the BD from the beginning, it is possible to save time and time for the user to transfer or move (move) the image data from the HDD to the BD later.

  Also, when there is no BD disc or when there is no remaining capacity on the BD, down-conversion recording is automatically performed on the DVD or BD. If the user does not select either BD recording or down-conversion recording while the BD automatic recording mode is set, recording is performed on the HDD in high definition. In this case, the HDD recording is recorded on the HDD with a status flag attached as a provisional recording, in distinction from the case of recording on the HDD from the beginning without setting the BD automatic recording mode.

  11 and 12 are subroutines showing the down-conversion process, and are called and executed by a subroutine call in step S8 in FIG. 10 or step S35 in FIG.

  First, in step S101, it is determined whether automatic execution is set in the down conversion setting table. The down-conversion setting table sets down-conversion conditions in advance, and is set according to FIG. If automatic execution is set in the down-conversion setting table, down-conversion to a DVD is immediately executed without waiting for user confirmation. If automatic execution is not set in the down-conversion setting table, a down-conversion execution confirmation message is displayed in OSD at step S102. The down-conversion execution confirmation message includes selection of a recording medium (BD or DVD) to be down-converted and down-conversion rate selection (image quality selection). The default is “DVD down-conversion” and “high image quality”. FIG. 16 is a diagram showing an example of a message 171 for down-conversion displayed on the broadcast screen 170 of the TV display unit (not shown). As shown in Fig. 16, “Reserved recording cannot be recorded in high-definition until the end of the program. If the down-converter is used, it is possible to record the whole volume. The down-conversion setting method is △△.” The message “Do you want to down-convert? Are you sure?” Is displayed in OSD. Further, a sound codec that digitally processes an output signal from the CPU 3 may be installed as a sound generator. The audio codec is composed of a PCM (Pulse Code Modulation) sound source IC or the like, and converts a signal received from the CPU 3 into an audio signal and outputs it from a speaker. In this case, an OSD display and a voice message may be used in combination.

  In step S103, it is determined whether or not down-conversion is to be executed. If down-conversion is not to be executed, this subroutine is terminated, and the process returns to step S8 in FIG. 10 or step S35 in FIG. When performing BD down-conversion, it is determined in step S104 whether or not the BD is in the tray. If the BD is not in the tray, a message “Prompt to insert BD in tray” in step S105. Please OSD "is displayed. When the BD is in the tray at step S104 or when the BD is inserted into the tray at step S106, the remaining capacity of the BD is detected at step S107. Next, in step S108, down-conversion recording is performed in a bit-rate recording mode that provides the highest possible image quality for the BD. In step S109, it is determined whether or not BD down-conversion recording has been completed. When the BD down-conversion recording is completed, a down-conversion end message is OSD displayed in step S110, this subroutine is terminated, and the process returns to step S8 in FIG. 10 or step S35 in FIG.

  On the other hand, if automatic execution is set in the down conversion setting table in step S101, or if DVD down conversion is executed in step S103, the process proceeds to step S111. That is, if automatic execution is set in the down-conversion setting table, the OSD display in step S102 and the user confirmation in step S103 are omitted, and the process proceeds to DVD down-conversion processing. As a result, a series of DVD down-conversion proceeds without forcing the user to confirm down-conversion execution.

  In step S111, it is determined whether or not the DVD is in the tray. If the DVD is not in the tray, the message “Please insert the DVD into the tray” prompting insertion of the DVD is displayed in OSD in step S112. When the DVD is in the tray at step S111 or when the DVD is inserted into the tray at step S113, the remaining capacity of the DVD is detected at step S114. Next, in step S115, the DVD performs down-conversion recording in a bit rate recording mode that provides the highest possible image quality. In step S116, it is determined whether the DVD down-conversion recording has been completed. When the DVD down-conversion recording is completed, a down-conversion end message is OSD displayed in step S117, this subroutine is ended, and the process returns to step S8 in FIG. 10 or step S35 in FIG.

  FIG. 13 and FIG. 14 are flowcharts showing recording data write-back processing for writing back HDD recording data to the BD.

  First, it is determined whether or not the BD automatic recording mode is set in step S21. If the BD automatic recording mode is set, it is determined whether or not the HDD has recording data of the flag “1” in step S22. When not in the BD automatic recording mode, or when there is recorded data with flag “1” in the HDD, this flow ends. If there is recorded data with flag “1” in the HDD, it is determined that there is temporary recorded data in the HDD, and a message to transfer the HDD recorded data to the BD is notified in step S23. For example, “Do you want to move the recorded data on the HDD to the BD? It takes about XX minutes.”, “Do you want to downconvert the recorded data on the HDD and record it on the DVD? It takes about XX minutes.” Is displayed in OSD. Moreover, the aspect which uses a voice message together may be sufficient.

  In step S24, it is determined whether or not the DVD is down-converted from the HDD. If the DVD is down-converted, the status flag of the corresponding recording data is lowered (set to "0") in step S35, and the down-conversion processing (FIGS. 11 and FIG. 11) is performed. 12 subroutine) is executed, and this flow is finished. The recording / reproducing apparatus A of the present embodiment is characterized in that digital broadcasting can be recorded on the HDD and BD as high-definition. The high-definition recording data of the HDD is bidirectional on the BD, and the high-definition recording data of the BD is bidirectional on the HDD. Can be moved or dubbed, but down-conversion is required when recording on a DVD. In this embodiment, from the viewpoint that there are few usage methods for down-converting data recorded on the HDD in high-definition BD to BD capable of high-definition recording, the HDD down-converts the DVD in step S24. You may enable it to select a medium.

  If the HDD is not downconverted in step S24, it is determined in step S25 whether or not high-definition video recording data is moved from the HDD to the BD. If HDD → BD high-definition video recording data is moved, the BD enters the tray in step S26. If the BD is not in the tray, the message “Please put BD in the tray” prompting the insertion of the BD is displayed in OSD in step S28. When the BD is in the tray in step S26 or when the BD is inserted into the tray in step S28, it is determined in step S29 whether or not the high-definition recording data movement is OK from the HDD to the BD. Since a certain amount of time is required for moving the high-definition video recording data, the user is asked for confirmation. For example, OSD displays a message such as “From now, the recorded data on the HDD will be transferred to the BD. It takes about XX minutes. Are you sure? Select the following menu if you want to move the recorded data later”. Confirm with the user. When the recorded data is transferred later, it waits until the time or condition (for example, when the user is not watching the broadcast program at night or when the user is out, etc.) when the execution instruction is given in step S30. . If the HDD → BD high-definition recording data movement is to be stopped, this flow is terminated as it is.

  When the high-definition video recording data can be moved from the HDD to the BD, in step S31, the video recording data is transferred from the HDD to the BD in high-vision, and it is determined whether or not the HDD → BD video recording data movement is completed. When the HDD → BD recording data movement is completed, the flag relating to the recording data such as the recording reservation whose data has been moved is set to “0” in step S33, and the HDD → BD movement end is OSD displayed in step S34, and this flow is ended. .

  On the other hand, if the HDD → BD high-definition recording data is not moved in step S25, the HDD → BD high-definition recording data is not instructed even though the BD automatic recording mode is present and there is provisional recording data in the HDD. In step S37, there is a message indicating that there is high-definition video recording data in the HDD. For example, “There is high-definition video recording data in the HDD. Do you want to leave it in the HDD as it is? OSD displays a message such as “△△” if it is to be converted, or “XX” if it is to be downconverted to a DVD. ” Next, in the case where the HDD high-definition recording data is stored until instructed in step S38, this flow is terminated as it is (flag “1” is held), and in the case where the HDD high-definition recording data is not stored, in step S39. A flag relating to recording data such as recording reservation is set to “0”, and this flow ends.

  FIG. 15 is a flowchart showing the operation of setting the BD automatic recording mode.

  First, at step S41, the BD automatic recording mode setting screen is OSD-displayed, and at step S42, a user setting input is awaited. When the user setting is completed, the down conversion setting screen is OSD-displayed in step S43, and the user setting input is waited for in step S44. In step S45, the user-set BD automatic recording mode and down-conversion settings are stored as table data. This table data is stored in a nonvolatile memory area of the CPU 3, for example. The recording / reproducing apparatus A has a feature capable of 6-way free dubbing and simultaneous recording / playback between HDD, BD, and DVD. In order to make better use of the feature, a user's usage mode is set in advance, and a recording operation or the like is performed. Prepare a BD automatic recording mode to support For example, “0. Use BD automatic recording mode” “1. Automatically record high-definition signals on BD” “2. If there is no BD, temporarily record to HDD” “3. Downconvert to DVD ”And the detailed information thereof are displayed on the OSD, and the user selects and sets the items and recording media in advance and stores them in a table. After the BD automatic recording mode is set, for example, when a high-definition signal is input to the recording / reproducing apparatus A, it is automatically recorded on the BD directly without being recorded on the HDD (this is an example of the setting, HDD / BD simultaneous recording, HDD Only recording is possible). At that time, it is also possible to omit the OSD display to notify the user and the confirmation instruction. In the down conversion setting, the down conversion execution condition, the priority order of the down conversion recording medium, and the like are set in advance.

  Note that the BD automatic recording mode setting and the down-conversion setting are only for simplifying the user operation and improving usability, and the mode-set function is only higher in the priority order. Even if the BD automatic recording mode setting is performed or not performed, the use form / function is not limited.

  As described above, the recording / reproducing apparatus A according to the present embodiment includes three drives, HDD, BD, and DVD, and the CPU 3 preferentially records the high-definition signal on any recording medium of BD or HDD. This is set in advance as a BD automatic recording mode, and when a high-definition signal is detected, the HDD 33, 35, and 31 drives 33, 35, and 31 are controlled to perform recording. In the first embodiment, when the BD automatic recording mode is set, the recording data is recorded in high definition with priority on the BD side. Since the high-definition signal is automatically recorded on the BD from the beginning, it is possible to save time and time for the user to transfer or move (move) the image data from the HDD to the BD later. Also, when there is no BD disc or when there is no remaining capacity on the BD, down-conversion recording is automatically performed on the DVD or BD. As described above, the high-definition signal is automatically recorded on the recording medium intended by the user regarding the recording of the recording / reproducing apparatus A, and when there is no remaining capacity in the BD, the recording is down-converted or temporarily recorded in the HDD. Recording and recording back to the BD at an appropriate time and conditions, making it possible to realize a usage method that takes advantage of the characteristics of the recorder with a built-in HDD, BD, and DVD drive capable of recording high-definition signals. Can be improved.

  In the present embodiment, the mode of provisional recording in the HDD is shown, but as shown in FIG. It is of course possible to continue recording on an external BD or HDD device connected to the LINK, and the same effect can be obtained.

  In this embodiment, the HDD or BD corresponds to the first and second recording media as the first and second recording media capable of recording the high-definition signal. More specifically, although BD corresponds to the first recording medium and HDD corresponds to the second recording medium, the present invention is not limited to this combination.

Second Embodiment The recording / reproducing apparatus according to the present embodiment, when automatically recording a high-definition signal of a broadcast signal on a BD, continuously records it on the HDD when the BD disk becomes full, and records the BD disk during recording on the HDD. Is exchanged, and the HDTV signal continuously recorded on the HDD is controlled to be automatically transferred to the BD disc.

  The hardware configuration of the recording / reproducing apparatus of the present embodiment is the same as that of the first embodiment shown in FIGS.

  17 and 18 are flowcharts showing the BD automatic recording operation of the recording / reproducing apparatus A according to the second embodiment of the present invention.

  First, in step S51, it is determined whether or not the BD automatic recording mode is set. The BD automatic recording mode is a mode for automatically recording a high-definition signal on a BD. Details of the BD automatic recording mode setting have been described with reference to FIG. If it is in the BD automatic recording mode, it is determined in step S52 whether or not the BD automatic recording condition is satisfied. The BD automatic recording condition is a condition for determining whether the current recording / reproducing apparatus A is in a device state capable of high-definition recording. For example, whether the broadcast signal is a high-definition signal or whether a BD disc is in the tray.

  In step S53, the type of broadcast signal is acquired. In step S54, it is determined whether or not the broadcast signal is a high-definition signal. If the broadcast signal is a high-definition signal, it is determined in step S55 whether or not high-definition reserved recording is specified. If high-definition reserved recording is specified, the remaining capacity of the BD disc is detected in step S56. In the processing so far, when the BD automatic recording mode is not set at step S51, when the BD automatic recording condition is not satisfied at step S52, when the broadcast signal is not a high-definition signal at step S54, or when the high-definition signal is set at step S55. When no reservation recording is designated, it is determined that the execution condition for the BD automatic recording operation is not satisfied, and this flow is ended.

  In step S56, the remaining capacity of the BD disc is detected, and in step S57, the reserved recording is recorded on the BD in high definition. Next, in step S59, it is determined whether or not the reserved recording has ended. When the reserved recording ends, this flow is ended as it is because the high-definition video can be recorded on the BD. If the scheduled recording has not ended, it is determined in step S59 whether or not the remaining capacity of the BD disc is full. If the remaining capacity of the BD disc is not full, the process returns to step S57 to perform high-definition recording on the BD. continue.

  When the remaining capacity of the BD disc is full, the continuous recording data of the reserved recording (hereinafter referred to as continuous recording data) that could not be recorded on the BD disc at the time when the BD disc is full in step S60 is recorded on the HDD in high definition. Record on. Next, in step S61, it is determined whether or not the reserved recording is finished. When the reserved recording is finished, it is a time when the continuous recording data has been recorded on the HDD in the high-definition, so the storage capacity of the continuous recording data in step S62. Is detected. In the process so far, when the BD disc is full, continuous recording data is automatically continuously recorded on the HDD. Thereafter, the process of automatically transferring the continuous recording data recorded on the HDD to the BD disc is performed.

  First, in step S63, a BD disk replacement message is displayed in OSD. The exchange message is, for example, “The BD disc is full. Please insert a new BD disc.” “If you do not want to record on the BD disc, you can down-convert to DVD. Please exit the message and perform the down-conversion operation from the BD automatic recording mode. " The down-conversion process has been described with reference to FIGS. A full-length recording method using down-conversion will be described later with reference to the third embodiment.

  In step S64, it is determined whether or not the high-vision continuous recording data movement from the HDD to the BD is OK. Since a certain amount of time is required for moving the high-definition video recording data, the user is asked for confirmation. For example, OSD displays a message such as “From now, the recorded data on the HDD will be transferred to the BD. It takes about XX minutes. Are you sure? Select the following menu if you want to move the recorded data later”. Confirm with the user. If the HDD → BD high-definition recording data movement is to be stopped, this flow is terminated as it is.

  If the HDD → BD high-vision continuous recording data movement is OK, it is determined in step S65 whether or not the BD is in the tray. If the BD is not in the tray, the message “Please put BD in the tray” prompting the insertion of the BD is displayed in OSD in step S63. When the BD is in the tray or when the BD is inserted into the tray in step S65, it is determined in step S66 whether or not there is enough free space for continuous recording data in the BD, and all the continuous recording data is recorded. If not, return to step S63 and prompt the message to insert a BD with sufficient free space “The free space on the BD disc is insufficient. The continuous recording time is about XX. Insert a new BD disc or cancel Please display a message such as "Please do". If continuous recording data can be recorded on the BD, the recording data continuously recorded on the HDD is transferred to the BD in step S67, and the continuous recording data movement from the HDD to the BD is OSD displayed in step S68.

  In step S69, it is determined whether or not the continuous recording data movement from the HDD to the BD is completed. If the continuous recording data movement from the HDD to the BD is not completed, the continuous recording data movement and the OSD display are continued in step S67. When the continuous recording data movement from the HDD to the BD is completed, the continuous recording data movement completion OSD display from the HDD to the BD is displayed in step S70, and this flow is finished. It is preferable to notify that this message is continuously recorded, for example, “The movement of the continuous recording data to the BD disc has been completed. The designated reserved recording is in two BD discs”.

  On the other hand, when the scheduled recording ends in step S58, it is a case where the entire BD is recorded on the BD disc and it is determined that the recording to the HDD is not necessary, and this flow is ended. If the high-definition continuous recording data movement from the HDD to the BD is not OK in step S64, this flow is terminated as it is a case where it has been canceled due to the user's intention.

  As described above, according to the recording / reproducing apparatus of the present embodiment, when the high-definition signal of the broadcast signal is automatically recorded on the BD, the BD disc is continuously recorded when the BD disc is full, and the BD disc is being recorded on the HDD. The high-definition signal continuously recorded on the HDD can be automatically transferred back to the BD disc.

Third Embodiment The recording / reproducing apparatus according to the present embodiment, when automatically recording a high-definition signal of a broadcast signal on a BD, if it does not completely enter the BD disc, down-converts the entire program to one BD disc. It is an example which performs control which records.

  The hardware configuration of the recording / reproducing apparatus of the present embodiment is the same as that of the first embodiment shown in FIGS.

  In the present embodiment, the CPU 3 in FIG. 5 further has CM detection and scene change detection functions. When the CM information is included in the program supplementary information superimposed on the broadcast signal, or when the CM information can be downloaded from the Internet, the CPU 3 detects the CM from the information. Actually, CM information is not always supplied by being superimposed on a broadcast signal or the like. Therefore, the CPU 3 detects CM from a television broadcast signal made up of video and audio signals. (1) CM is detected from the difference in broadcasting system between stereo broadcasting [CM] and monaural broadcasting or bilingual broadcasting [main edition], (2) scene change point of image from video signal in silent section of audio signal There is a method of detecting CM and detecting CM from its regularity. In the method (1), CM detection can be easily detected, but cannot be detected when the main part is a stereo broadcast. Although the method (2) is slightly complicated, the CM can be detected with high accuracy. In the present embodiment and each embodiment described later, the method (2) is adopted in order to ensure the image display control accuracy in the CM detection. However, this process can be omitted or skipped if EPG and CM information can be reliably acquired from the program supplementary information superimposed on the broadcast signal.

  FIG. 19 is a flowchart showing the BD automatic recording operation of the recording / reproducing apparatus A according to the third embodiment of the present invention. Steps for performing the same processing as in the flow of FIG. Omitted.

  When the remaining capacity of the BD disc is detected in step S56, it is determined in step S71 whether or not the entire scheduled recording can be recorded on the BD disc. Whether or not the entire scheduled recording can be recorded on the BD disc can be calculated from the remaining capacity of the BD disc and the high-definition scheduled recording time. When the entire reserved recording can be recorded on the BD disc, the entire reserved recording is recorded in high definition in step S72, and it is determined in step S73 whether or not the reserved recording is completed, and the BD recording is performed in high definition until the reserved recording ends. continue. This flow ends when the scheduled recording ends.

  On the other hand, when it is not possible to record the entire scheduled recording on the BD disc in step S71, the process proceeds to the entire recording process in step S74 and this flow is terminated.

  FIG. 20 is a subroutine showing the full-length recording process, and is called and executed by a subroutine call in step S74 of FIG.

  First, a scheduled down-conversion switching time is set in step S201. The scheduled down conversion switching time will be described. When the entire scheduled recording does not fit on the BD disc, it is down-converted and recorded on one BD disc. Down-conversion reduces image quality compared to high definition. Further, as shown in FIGS. 7 and 9, in the down-conversion, there are recording modes with a plurality of bit rates, and the higher the bit rate, the better the image quality but the shorter the recordable time. Therefore, in this embodiment, even when down-converting from high-definition recording, the timing for switching from high-definition to down-conversion is automatically set as the scheduled down-conversion switching time so that the image quality is as low as possible and the image quality is as low as possible. is there. Since HDTV has extremely high image quality and high definition, when switching to down-conversion, if the recording mode of down-conversion is not high-quality, the user is strongly impressed when image quality is switched from high-definition to down-conversion. On the other hand, there is a demand for recording on a BD disc with high-definition video as long as possible. For example, if high-definition recording is performed on a BD disc until the remaining capacity is low, the remaining reserved recording portion must be down-converted and recorded in a mode with a low bit rate (poor image quality). In the present embodiment, a scheduled down-conversion switching time is set in step S201 so that the video recorded on one BD disc has as high image quality as possible and the switching point is not noticeable. Switch from to down-conversion. As an example, down-conversion is set to a recording mode with the highest image quality, and the high-definition recording is continued until the limit time at which the entire reserved recording can be recorded on one BD disc by the recording mode with the highest image quality. In step S201, the scheduled down-conversion switching time is calculated based on the combination of the remaining capacity of the BD disc, the reserved recording time of the entire volume, and the down-conversion recording mode.

  Returning to the flow of FIG. 20, it is determined whether or not high-definition recording is performed at the beginning of reserved recording. If high-definition recording is performed from the beginning of reserved recording, high-definition recording is performed on the BD in step S203. Next, in step S204, it is determined whether or not it is a preparation period preceding the scheduled down-conversion switching time. In the present embodiment, a preparation period is provided prior to the scheduled down-conversion switching time, and it is determined whether or not there is a timing at which switching from hi-vision to down-conversion is not noticeable during this preparation period. As the timing at which switching is not conspicuous, for example, CM time or scene change time is used, but it is not limited to this.

  During the preparation period of the scheduled down-conversion switching time, it is determined whether or not a commercial is being performed in step S205, and if it is not during a commercial, it is determined whether or not a scene change is being performed in step S206. If it is not a scene change, it is determined in step S207 whether or not the scheduled down-conversion switching time has elapsed. If the scheduled down-conversion switching time has not elapsed, the process returns to step S204.

  When the scheduled down-conversion switching time is reached in step S207, the high-vision is switched to down-conversion recording in step S208. If a CM or a scene change is detected during the preparation period for the scheduled down-conversion switching time, the process proceeds to step S208 without waiting for the scheduled down-conversion switching time to switch to down-conversion recording. As a result, switching from high-definition to down-conversion is not conspicuous at the time of CM or scene change, and down-conversion can be avoided for the user due to down-conversion.

  In step S209, the entire scheduled recording is recorded on one BD by down-conversion. In step S210, it is determined whether or not the BD down-conversion recording is completed, and the BD down-conversion recording is continued until the recording is completed. When the BD down-conversion recording is completed, a down-conversion recording end message is OSD displayed in step S211, and the process returns to step S74 in FIG. In the down-conversion recording end message, in addition to “Recording by down-conversion has ended.”, “Since the scheduled recording does not fit on the BD disc, it was down-converted and the entire volume was recorded on one BD disc.” It is preferable to display such a message.

  As described above, according to the recording / reproducing apparatus of the present embodiment, when the high-definition signal of the broadcast signal is automatically recorded on the BD, the remaining capacity of the BD disc is detected. Since the entire program is recorded on one BD disc, the entire program can be recorded on one BD disc.
