Description

  The present invention relates to a recording apparatus for recording a broadcast program on an optical disc such as a DVD (Digital Versatile Disk) or a CD-ROM.

  In an optical disc such as a DVD-R that is inexpensive or has a warped disc, the writing of data at the outer periphery may become unstable. With such an optical disc, the finalization after the recording of the broadcast program has failed, and the recorded broadcast program cannot be viewed at all.

In order to prevent the occurrence of such a situation, a recording apparatus that adjusts the data writing position on the recording layer of the optical disk based on error information generated during recording on the optical disk is conventionally known. (For example, refer to Patent Documents 1 and 2). In addition, a recording apparatus is known that adjusts data writing to the recording layer of an optical disc in accordance with media information such as an optical disc manufacturer, product type, and manufacturing region (for example, Patent Document 3). reference).
JP 2004-110964 A JP 2004-227733 A JP 2004-342217 A

However, in the recording apparatuses described in Patent Documents 1 and 2, the writing operation to the optical disc must be performed at least once. Further, although the recording apparatus described in Patent Document 3 is not described in the document, in order to acquire information on such an optical disk manufacturing manufacturer, the writing operation to the optical disk is once performed again. It must be made.
On the other hand, it is often the case that the user recognizes in advance that the optical disk is warped or that the purchased optical disk is inexpensive and likely to cause a problem in writing. A configuration in which once writing to the optical disk is performed and then a determination is made as to whether or not a writing error occurs on the optical disk is inconvenient.

  In view of such circumstances, the present invention is intended to provide a recording apparatus that is excellent in convenience in storing information about an optical disc that may or may have a writing error.

  In order to achieve the above object, according to a second aspect of the present invention, a broadcast program to be received is recorded on an optical disc by controlling each part of the apparatus by a control means based on an instruction from an operation part having a plurality of keys.

Record on. Further, the recording device sets the recordable time of the optical disc to be small in response to the predetermined condition being satisfied. When an instruction is input from the user or when it is recognized that there is a possibility that a write error may occur on the optical disk, the maximum recording time that can be recorded on the optical disk is reduced. Set the recordable time of the optical disc. For example, when the maximum recording time of the optical disc is 120 minutes, the recordable time is set to 90 minutes, and the remaining 30 minutes are not recorded. By doing so, data writing to the outer peripheral portion of the optical disk is prohibited, and the occurrence of data writing errors due to warpage of the optical disk or the like can be suppressed.

  In addition, the recording apparatus includes a disk related information storage unit that stores disk related information regarding the optical disk when recording fails. That is, when recording of a broadcast program on the optical disc fails due to warping of the optical disc, the disc-related information related to the optical disc is stored in the disc-related information storage means. The disc-related information is not particularly limited as long as it is information that can specify an optical disc that has failed to be recorded. For example, a manufacturer code, a manufacturer ID, a product code, a manufacturing factory ID for identifying a manufacturer , Serial number, country / region of manufacture, etc.

  The recording apparatus includes writing means that enables writing of the disc related information to the disc related information means by operating the key of the operation unit. That is, the disc related information can be written by operating the operation unit of the user. With this configuration, when the user recognizes that there is a possibility of a write error on the optical disc, the disc-related information of the optical disc is mainly sent to the recording device by the user. Since it can be memorized, it is excellent in convenience.

According to a third aspect of the present invention, the control means sets the recordable time of the optical disc to be small in response to insertion of the optical disc related to the disc related information stored in the disc related information storage means. Is configured.
In the invention according to claim 3 configured as described above, when the optical disc related to the disc related information stored in the disc related information storage means is inserted, the recordable time is automatically set to be short. As a result, writing of data to the outer peripheral portion is automatically prohibited when an optical disc that may cause a writing error is inserted. Recording can be performed reliably.

According to a fourth aspect of the present invention, when the control means performs reserved recording, the bit rate is lowered if the broadcast time of the broadcast program reserved for recording is longer than the set recordable time. It is configured to record by setting.
In the invention according to claim 4 configured as described above, even if the recordable time is shortened, the broadcast program is surely recorded even if it is shorter than the broadcast time of the broadcast program reserved for recording. Is possible.

The invention according to claim 5 is configured such that the recordable time of the optical disc can be set.
In the invention according to claim 5 configured as described above, the recordable time of the optical disc can be set within a range in which the optical disc is shorter than the original recordable time.

In the invention according to claim 2 of the present invention, when the user recognizes that there is a possibility of writing error of the optical disc, the user mainly gives the disc related information of the optical disc by the user. Since it can be stored in the recording apparatus, it is excellent in convenience.
In addition, the invention according to claim 3 is excellent in convenience and can reliably record the broadcast program on the optical disc.
In the invention according to claim 4, as a result of shortening the recordable time, even if the broadcast time of the broadcast program reserved for recording becomes shorter, it is possible to reliably record all the broadcast programs. .
In the invention according to claim 5, it is possible to set the recordable time of the optical disc within a range in which the optical disc is shorter than the original recordable time.

Hereinafter, embodiments of the present invention will be described in the following order.
(1) First embodiment:
(2) Various modifications:
(3) Summary:

(1) Configuration of recording / reproducing apparatus:
Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a block diagram illustrating a schematic configuration of a recording / reproducing apparatus according to the embodiment. In the present embodiment, a case will be described in which the present invention is applied to a recording / reproducing apparatus having a recording function for recording a broadcast program and a reproducing function for reproducing a recorded broadcast program. The recording / reproducing apparatus 1 records a television broadcast program on a rewritable optical disc 10 (DVD-RW, etc.) and a write-once optical disc 10 (DVD-R, etc.), and the optical disc 10 (DVD-R, DVD). -Broadcast programs and video data recorded on RW, DVD-ROM, etc.). The configuration of the recording / reproducing apparatus 1 is the same as that of a conventional recording / reproducing apparatus in hardware except that a reliable recording key to be described later is provided on the remote controller 20.

  Hereinafter, the recording / reproducing apparatus 1 will be described with reference to FIG. The control unit 18 includes a CPU 18a, a memory 18b, and a control circuit (not shown), and controls each unit of the recording / reproducing apparatus 1 when the CPU 18a executes a program stored in the memory 18b. Broken lines with arrows in the figure indicate the flow of control signals and control data. The memory 18b is also used as a storage area for various control data, a calculation work area for the CPU 18a, and the like.

  As shown in FIG. 2, the remote controller 20 includes a power switch 21 and a number of keys 22 (definite recording key 22a, menu key 22b, recording key 22c, playback key 22d, stop key 22e, Key 22f, cursor sol 22g, etc.). When the key 22 of the remote controller 20 is pressed, a signal of the pressed key 22 is transmitted to the control unit 18, and the control unit 18 controls each unit according to the key operation, whereby the optical disc 10 of the broadcast program is displayed. Recording and playback of recorded broadcast programs are performed. Although not shown in FIG. 1, a power switch, a reliable recording key, a recording key, a reproduction key, and a stop key are also provided on the operation panel 19 disposed on the front surface of the casing of the recording / reproducing apparatus 1. -Etc. are provided. In the following description, it is assumed that only the key 22 of the remote controller 20 is pressed. The clock IC 17 stores the current date and time (hereinafter referred to as the date and time together), and the control unit 18 reads and writes the date and time data.

  The broadcast receiving unit 12 selects a broadcast signal received by the antenna 11, further amplifies and detects the selected broadcast signal, and outputs a video signal and an audio signal. Each of the video signal and the audio signal is A / D converted by the recording signal processing unit 13, compressed and encoded, and written (recorded) on the optical disk 10 by the recording / reproducing unit 14. The recording / reproducing unit 14 includes a modulation circuit that modulates a compression-coded video signal and audio signal into a write signal on the optical disc 10, a demodulation circuit that demodulates a signal read from the optical disc 10, an optical pickup, and the optical disc 10. The tray includes a tray to be set, a rotation drive mechanism for rotating the optical disc 10, and the like.

  On the other hand, the signal read (reproduced) from the optical disc 10 by the recording / reproducing unit 14 is separated into a video signal and an audio signal by the reproduction signal processing unit 15, and the separated signal is decompressed and compounded after the separation. / A conversion. The D / A converted audio signal is input to the audio signal input terminal of the television 30. The OSD processing unit 16 superimposes the OSD signal on the D / A converted video signal. The OSD signal is an on-screen display signal generated by the control unit 18, and is output from the control unit 18 when on-screen display is performed on the screen of the television 30. Then, the output signal of the OSD processing unit 16 is input to the video signal input terminal of the television 30 (a display device connected to the outside).

  The data of the broadcast program recorded as described above is recorded in the data area of the optical disc 10 as a file for each recording operation (that is, for each broadcast program (title)). Also, file management information (recording start address, recording size, etc.) is recorded in the management area of the optical disc 10. Accordingly, the recorded broadcast program is erased by rewriting the file management information rather than erasing the data itself recorded in the data area. When broadcast program data is recorded in almost the entire area of the DVD-RW, the time required to rewrite the management information of all broadcast program files is about one minute.

Below, the case where the optical disk inserted in the recording / reproducing apparatus 1 is DVD-R is demonstrated.
FIG. 3 is an explanatory diagram for explaining the layout of the recording layer of the DVD-R. As a logical data layout in the recording layer of the DVD-R, an information area is formed from the inner circumference side to the outer circumference side of the disc. This information area is an area that includes all information necessary for ensuring data recording compatibility and reproduction compatibility.

  The information area is mainly composed of the following five areas. That is, it is composed of five areas: an inner drive area, a lead-in area, a data area, a lead-out area, and an outer drive area. Of these five areas, the lead-in area, the data area, and the lead-out area are areas that can be accessed without any problem even by a reproduction-only device. On the other hand, the inner drive area and the outer drive area are areas dedicated to the recording apparatus. When recording information, it is necessary to adjust the laser power during recording so that a correct recording mark can be formed. For this reason, test zones that can be used for test recording for obtaining optimum recording conditions and areas for recording management information relating to the recording conditions are formed in the inner drive area and the outer drive area.

  The data area is basically an area where user data is recorded. In the present embodiment, the data area is an area where broadcast programs are recorded as data. In the lead-out area, information indicating the end position of the data area (read-out data) is recorded. Note that management information may be recorded in this lead-out area. An area from the lead-out area where the lead-out data indicating the end position of the data area is stored to the outer drive area is an unrecorded area where no data is recorded.

  In FIG. 3, the data area where the broadcast program is recorded and the unrecorded area are 120 minutes in total. That is, in this DVD-R, when a broadcast program is recorded until the maximum recording time is reached, that is, when recording is performed until the unrecorded area disappears, 120 minutes can be performed. However, in the example shown in FIG. 3, since the recorded program is less than 120 minutes, the data area ends at a position of less than 120 minutes in terms of the time of the broadcast program, and then the lead-out area. Is formed.

  As described above, when the DVD-R is inexpensive, or when the disc is warped, data writing in the outer peripheral portion (right direction in FIG. 3) of the disc is not possible. May become stable. Therefore, in the recording / reproducing apparatus 1 according to the embodiment, when there is a possibility that a write error may occur in the inserted DVD-R when the certain recording key 22a is pressed, the end of the data area is reached. The position where the above lead-out data indicating the position is recorded is set on the inner circumference side of the disc so that no further recording of the broadcast program is performed. For example, when the certain recording key 22a is pressed and it is determined that the DVD-R has a possibility of writing error, the position where the read-out data is written is 0 to 90 as the recording time. Minutes are set so that no read-out data is written in an area of 90 to 120 minutes. Thereby, the recordable time of the DVD-R is set to 90 minutes.

  In the recording / reproducing apparatus 1 according to the present embodiment, as described above, when the certain recording key 22a is pressed, the inserted DVD-R, that is, the DVD-R from which a broadcast program is to be recorded will be recorded. When there is a possibility that a writing error will occur, recording is performed by reducing the recordable time from the maximum recording time. However, the memory 18b determines whether or not there is a possibility that a writing error may occur. Is performed based on the disc-related information stored in. That is, the memory 18b functions as the disk related information storage means. The disc-related information is information for identifying the DVD-R that was to be recorded when the recording of the broadcast program has failed in the past, and is recorded in a predetermined area in the recording layer of the DVD-R. It is what. In the present embodiment, it is assumed that the disc-related information of this DVD-R is recorded in the inner drive area (see FIG. 3). When the recording / playback apparatus 1 fails to record the broadcast program, the recording / reproducing apparatus 1 reads the disc related information recorded on the DVD-R involved in the failure, and stores the read disc related information in the memory 18b.

  FIG. 4 is a diagram showing the disk related information stored in the memory 18b. In the figure, a state in which a plurality of disc related information is stored in the memory 18b of the recording / reproducing apparatus 1 is shown. In this embodiment, three pieces of disk-related information are stored as disk-related information: a manufacturer code that identifies a manufacturer, a product code that identifies a product, and a serial number. ing. For example, in the inner drive area of a DVD-R that has failed to be recorded, there are three pieces of disc-related information: the manufacturer code “aaa”, the product code “bbb”, and the serial number “ccc”. Is stored, and is read and stored in the memory 18.

  In the case shown in FIG. 4, three types of disc-related information are stored in the memory 18b, but it is determined whether or not the newly inserted DVD-R may cause a write error. At this time, all of these three disk-related information may be referred to, or one or two kinds of disk-related information may be referred to. In the following description, the above determination is made with reference to two of the three types of disk-related information shown in FIG. 4: the manufacturer code and the product code. That is, whether or not both the manufacturer code and the product code stored in the DVD-R inserted for recording coincide with those stored in the memory 18b. Determine.

  Hereinafter, the operation of the recording / reproducing apparatus 1 will be described. When the reliable recording key 22a of the remote controller 20 is pressed, the recording process shown in FIG. 5 is called and executed from a main routine (not shown). In this recording process, when the disc related information stored in the DVD-R inserted to record the broadcast program is also stored in the memory 18b, the recordable time of the DVD-R as the optical disc is calculated. In this process, recording is started by setting the recording time shorter than the maximum recording time of the DVD-R. In the following description, it is assumed that a DVD-R is set on the tray of the recording / reproducing apparatus 1 as the optical disc 10.

  First, the control unit 18 determines whether or not the optical disc 10 (DVD-R) is a recordable medium (S1). In this determination, the optical disk set in the tray is a disk that cannot be recorded by the recording / reproducing apparatus 1 or a broadcast program has already been recorded on the DVD-R, and additional recording is impossible. Check whether there is any. If the medium is not recordable (S1: NO), the control unit 18 outputs an error message display signal (S6). Specifically, on-screen display data is generated and transmitted to the OSD processing unit 16. As a result, an error message indicating that the medium cannot be recorded is displayed on the screen. If it is a recordable medium (S1: YES), the control unit 18 reads the disc related information from the DVD-R (S2). In this process, the control unit 18 reads disc related information (maker code and product code) stored in the inserted DVD-R.

  If the process of step S2 is executed, it is next determined whether or not it matches the disc related information stored in the memory (S3). In this process, the disc related information (see FIG. 4) stored in the memory 18b of the recording / reproducing apparatus 1 is the disc related information (maker code and product code) read out in step S2. It is determined whether or not it matches. For example, if the maker code read from the DVD-R is “ddd” and the product code is “eeee”, it is determined that they match.

If it is determined that the disc-related information matches the information stored in the memory (S3: YES), the control unit 18 shortens the recordable time of the DVD-R (S4). In this process, the position where the lead-out data indicating the end position of the data area, which is the area where the broadcast program is recorded, is set in advance so as to be shorter than the maximum recording time of the DVD-R. To do. By executing the process in step S4, for example, when the maximum recording time of the DVD-R inserted in the tray is 120 minutes, the recordable time is set to 90 minutes. When the recordable time on the DVD-R is shortened, the shortened time may be fixed (for example, 30 minutes) or may be arbitrarily set. When the recordable time is set shorter than the process in step S2, the control unit 18 starts the recording process (S5) and returns the process step to the caller.
On the other hand, if it is determined that it does not match the disc related information stored in the memory (S3: NO), the recordable time reduction setting in step S4 is not performed, and the recording process is started as it is (S5).

  As described above, when there is a possibility of writing error in the inserted DVD-R by simply pressing the reliable recording key 22a, the recordable time of the DVD-R is set to a predetermined time from the maximum recording time ( 30 minutes), and data writing to the outer peripheral portion of the recording layer of the DVD-R is intentionally stopped. As a result, when the user recognizes that the purchased DVD-R is inexpensive or warped, the user can simply press the reliable recording key. Since it is possible to reliably record a broadcast program, it is excellent in convenience.

In the above description, a case has been described in which the recordable time of the DVD-R is set to be shortened by pressing the certain recording key 22a, and recording is started immediately thereafter. The case of reservation will be described.
FIG. 6 is a flowchart showing the processing contents of a recording reservation process for making a recording reservation for a broadcast program. FIG. 7 is a diagram showing a recording reservation screen that is displayed on-screen on the screen of the television 30 at the time of recording reservation.

  When the menu 22b or the like is pressed when making a recording reservation, the recording reservation screen 50 is displayed on-screen, and the recording reservation process is called from the main routine and executed. On the upper side of the recording reservation screen 50, a recording reservation input screen 51 is displayed, and on the lower side, a recording reservation list 52 showing the contents of the recording reservations already performed is displayed. The recording reservation list 52 displays a recording reservation table for storing the contents of the recording reservation in a table format. The recording reservation table is stored in the memory 18b of the control unit 18. When the recording reservation screen 50 is displayed, the cursor start key 22f, the decision key 22f, etc. are operated in the same manner as in the past to specify the recording start time and whether or not to erase all broadcast programs. Recording reservation information is shown on the input screen 51.

  In the recording reservation process (FIG. 6), the control unit 18 determines whether or not all recording reservation information has been input to the input screen 51 (S21), and when all the recording reservation information has been input (S21: YES). ), Whether or not certain recording has been designated is determined. If certain video recording is designated (S22: YES), the disc related information (maker code and product code) is read from the DVD-R (S23), and then the DVD is read. It is determined whether or not the disc related information read from -R matches the disc related information stored in the memory (S24).

  If it matches the disc related information stored in the memory (S24: YES), the DVD-R can be recorded for a shorter recording time (S25). Once step S25 has been performed, it is next determined whether or not the program time is longer than the recordable time (S26). In this process, it is determined whether or not the broadcast time (program time) of the broadcast program to be reserved is longer than the recordable time of the DVD-R set to be shortened in step S25. If the program time is longer than the recordable time, it means that it is not possible to record all broadcast programs that are scheduled to be recorded.

When the program time is longer than the recordable time (S26: YES), processing for changing (decreasing) the bit rate of recording the broadcast program is performed (S27). When the bit rate is reduced, the amount of data per unit time is reduced. Therefore, even if the position where the lead-out data is recorded is the same, the recordable time is increased and scheduled recording is performed. It is possible to record all the broadcast programs to be recorded. If the process of step S27 is executed, or if reliable recording is not specified in step S22, if it does not match the disc related information stored in the memory in step S24, or the program time can be recorded in step S26 If it is determined that it is not longer than the time, the input recording reservation information is registered in the recording reservation table (S25), and the processing step is returned to the caller.
When the recording reservation process shown in FIG. 6 is executed and the recording start time is reached, the recording of the broadcast program is started. However, when the recording time reaches the recordable time set in step S25, the recording is started. It ends.

  As described above, by specifying the reliable recording when making the recording reservation, the recordable time of the DVD-R is shortened, and the data is intentionally written to the outer peripheral portion of the recording layer of the DVD-R. No longer done. As a result, when the user recognizes that the purchased DVD-R is inexpensive or warped, a simple operation of specifying certain recording at the time of recording reservation is performed. Thus, since it is possible to reliably record a broadcast program, it is excellent in convenience.

The above-described disc-related information is read from the inserted DVD-R and stored in the memory 18b when recording fails, but the recording / reproducing apparatus according to the present embodiment is a user. The disk-related information stored in the inserted DVD-R can be stored in the memory 18b by the operation of the key 22 of-. Hereinafter, writing of disc related information by user operation will be described.
When the menu key 22b of the remote controller 20 is pressed while a recordable DVD-R is inserted, the writing process shown in FIG. 8 is called from a main routine (not shown) and executed. First, the control unit 18 determines whether or not there is a write instruction (S31). In this process, when the menu key 22b is pressed and the menu screen is displayed, it is determined whether or not there is an instruction to write the disk related information to the memory 18b. When there is no writing instruction (S31: NO), the processing step is returned to the caller. On the other hand, when there is a write instruction (S31: YES), the disk related information stored in the DVD-R is read (S32), and the read disk related information is stored in the memory 18b of the recording / reproducing apparatus 1. A process of storing is performed (S33).

  (3) Various modifications:

However, if the recording apparatus has a broadcast program recording function, Well, it is not always necessary to have a playback function.
In the above-described embodiment, the recording / reproducing apparatus 1 and the television 30 are separate apparatuses. However, the recording apparatus of the present invention includes a recording / reproducing apparatus constituting a recording / reproducing apparatus integrated television.
Furthermore, in the above-described embodiment, the case where the DVD-R is applied as the optical disc has been described. However, the optical disc on which the recording apparatus of the present invention records a broadcast program is not limited to the DVD-R, and the DVD -RW, DVD + R, DVD + RW, CD-R, CD-RW, etc. can be applied.

(4) Summary:
As described above, according to the recording / reproducing apparatus 1 according to the embodiment, with the DVD-R inserted, the menu 22b is pressed to display the menu screen, and a predetermined operation is performed. As a result, the disc-related information (maker code and product code) stored in the inner drive area of the DVD-R can be written to the memory 18b. If the user recognizes that there is a possibility of writing error due to the purchase of a DVD-R at a low price or the warpage of the disc, the disc related to the DVD-R Since the information can be stored in the recording device by the user, it is excellent in convenience.
