Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mini disc (hereinafter, also referred to as MD) which reproduces information (hereinafter, also referred to simply as information) such as music recorded on a compact disc (hereinafter, also referred to as CD) at a high speed. ) And a dubbing apparatus for recording data on a recordable disc such as a CD-R at high speed, and a control method therefor.

[0002]

2. Description of the Related Art An outline of a conventional dubbing apparatus and its control method will be described below with reference to two examples. Below, CD
A conventional dubbing apparatus having a so-called high-speed dubbing function of reproducing information recorded on a recordable disc in a shorter time than real time and recording it on a recordable disc at a higher speed than real time.
The case of recording in D will be described as an example. First, a first conventional example will be described. In the first conventional dubbing apparatus,
CD playback means for reproducing information recorded on a CD at high speed, MD recording means for recording information on an MD at high speed, and system control means for controlling the CD reproduction means and MD recording means; The recorded information is reproduced and recorded on the MD at high speed. In high-speed dubbing from a CD to an MD, synchronous recording (synchronized recording) is performed by the system control means. Synchronous recording from a CD to an MD is disclosed in, for example, Japanese Patent Application Laid-Open No. H7-110978, so that the description is simplified here.

The first conventional dubbing apparatus has a function for preventing high-speed dubbing of the same information two or more times within a predetermined time. That is, after high-speed dubbing a certain track of a CD, high-speed dubbing of the track or a CD including the track is prohibited until a certain time has elapsed, and when a certain time has elapsed since the first dubbing, This is to release the high-speed dubbing prohibition. The following method is employed as one method for providing this function.

That is, an ISRC (International Standard Recod) unique to each track of a CD is previously assigned to each track.
ing Code). When an ISRC of a certain track is detected when a CD is reproduced in high-speed dubbing, the ISRC is stored in a high-speed recording management table recorded in a memory 29 such as an SRAM. At the same time, the timer is started, and if the user attempts to perform high-speed dubbing on the same track or a CD including the track again within 74 minutes thereafter, high-speed dubbing is prohibited. On the other hand, when 74 minutes have elapsed without detecting the track after the ISRC of the track is first detected, the IRC
The SRC is deleted from the high-speed recording management table to permit high-speed dubbing.

Next, a second conventional example will be described. In the second conventional dubbing apparatus, a CD reproducing means capable of reproducing information recorded on a CD at a high speed, an MD recording means capable of recording information on an MD at a high speed, the CD reproducing means and the M
D control means for controlling the recording means,
The point that the information recorded on D is reproduced and the information is recorded on MD at high speed is the same as the first conventional example. After high-speed dubbing a certain track of the CD, high-speed dubbing of the track or a CD including the track is prohibited until a certain time has elapsed, and when a certain time has elapsed since the first dubbing, The first is that the high-speed dubbing prohibition is released.
Is the same as the conventional example.

However, the technique for providing the high-speed recording inhibition function is different between the first conventional example and the second conventional example. That is, in the second conventional dubbing apparatus, in order to provide the high-speed recording prohibition function, the TOC (Table of Content) of the CD is used instead of the ISRC attached to each track.
s) The difference is that information is used, and the track for which high-speed dubbing is prohibited is specified using the track number and the TOC information of the CD including the track.

More specifically, in the second conventional dubbing apparatus, the track number of a track on which high-speed dubbing has been performed is associated with the TOC information of the CD including the track and stored in the high-speed recording prohibition management table. Until a predetermined time (for example, 74 minutes) elapses from the first high-speed dubbing, high-speed recording of the same track or a CD including the track is prohibited. On the other hand, after the high-speed dubbing of the track is performed, when 74 minutes have elapsed without reproducing the track at all, the track number of the track and the CD of the CD stored in association with the track number are stored. The TOC information is deleted from the high-speed recording management table to permit high-speed dubbing.

In this case, it is determined whether or not high-speed recording of information of a certain track or a certain CD is permitted. For a track to be subjected to high-speed dubbing, a track having the same track number and TOC information is set to the high-speed recording prohibition. This is performed based on whether or not it is stored in the management table. That is, for a certain track to be subjected to high-speed dubbing, the track number of the track and the TOC information of the CD including the track are associated with the track number and the track number stored in the high-speed recording prohibition management table. The TOC information is compared with the TOC information. If there is a matching track, high-speed recording (high-speed dubbing) is prohibited for that track. Allowed.

[0009]

However, in the first prior art dubbing apparatus, when information is dubbed at a high speed in units of CDs or tracks, the ISRC of the track is first detected during the high speed dubbing. At that time, the ISRC is stored in the high-speed recording prohibition management table in the memory at that time, and the timer is started. If the user starts reproducing the CD and recording the MD in order to perform high-speed dubbing on the CD or the track again before 74 minutes have elapsed from this time, the high-speed recording is performed from the digital audio signal read from the CD. If there is an ISRC that is the same as the ISRC stored in the prohibition management table, high-speed dubbing prohibition of the track is displayed and recording on the MD is stopped.

For this reason, the user cannot know whether or not high-speed dubbing of the information is permitted before starting high-speed dubbing, and within a predetermined time after the ISRC of the track is first detected, If high-speed dubbing of the CD is attempted again, high-speed dubbing is prohibited after recording in high-speed dubbing is started. And C
In a non-rewritable recording medium such as DR, a recording area is wasted.

As a solution to the above problem, the timing of starting recording on the MD is delayed from the start of reproduction of CD by a time sufficient for detecting ISRC, and ISRC is detected and high-speed recording is permitted. After the confirmation, it is conceivable to start reproduction from the beginning of the track of the CD and start recording on the MD, but there is a problem that control of recording / reproduction becomes complicated. This problem is exacerbated when, for example, it is desired to perform high-speed dubbing of the entire CD including the track immediately after high-speed dubbing of some tracks.

In the second prior art dubbing apparatus, a track (or a CD including the track) for which high-speed recording is prohibited is specified by a track number and TOC.
Use information. For this reason, a CD on which ISRC is not recorded is also a management target of high-speed recording prohibition, and high-speed recording is prohibited more than necessary. The present invention has been made in view of the above problems, and has as its object to provide a dubbing apparatus and a control method of a dubbing apparatus capable of discriminating at an early stage whether dubbing of a track or a CD to be dubbed at a high speed is permitted or not. It is to provide.

According to the dubbing apparatus of the present invention, the ISRC
For a CD on which high-speed dubbing is not performed, high-speed recording is always permitted because a high-speed dubbing track is not stored in the high-speed recording prohibition management table. For a CD on which ISRC is recorded, a certain high-speed dubbing target track is recorded. The track number and TOC information, and the track number and T stored in the high-speed write inhibit management table
By prohibiting high-speed recording only on the track whose OC information matches, the danger of prohibiting high-speed recording more than necessary can be avoided.

According to a fifth aspect of the present invention, in the dubbing apparatus according to any one of the first to fourth aspects, when a predetermined time elapses after the ISRC of a certain track to be subjected to high-speed dubbing is first detected, the ISRC is first activated. And the TOC information stored in association with the track number detected in the high-speed recording prohibition management table.

FIG. 2 is a flowchart showing an embodiment of a method for controlling a dubbing apparatus according to the present invention.
This is an example of high-speed dubbing. The control method of the dubbing apparatus of this embodiment is applied to the dubbing apparatus 10 shown in FIG. The processing shown in the flowchart of FIG.
This is a process that is always executed when dubbing from a disc to an MD. When the information of a certain track is firstly dubbed at a high speed, the ISRC detecting means 21 of the high-speed recording prohibition determining means 25 detects the ISRC of the track. If this is the case, the track number of the track and the TOC information of the CD are stored in association with each other in the high-speed recording prohibition management table written in the memory 29 such as an SRAM.

Then, a certain time (74 minutes) from this time
If the user attempts to perform high-speed dubbing on the same track again, the TOC information comparison unit 23 of the high-speed recording prohibition determining unit 25 sets the track number of the track and the TOC information of the CD including the track, and the high-speed recording prohibition. The track number stored in the management table is compared with the TOC information of the CD stored in association with the track number, and the same track as the track is detected from the list in the high-speed recording prohibition management table. Then, the high-speed recording prohibition determining means 25 prohibits high-speed dubbing of the track.

Also, until a certain time (74 minutes) elapses after the ISRC of a certain track is first detected, the corresponding IS stored in the high-speed recording prohibition management table.
When the reproduction of the track corresponding to the RC has not been performed, the high-speed recording prohibition determining means 25 releases the high-speed dubbing prohibition of the track, and associates the high-speed recording prohibition management table with the track number and the track number from the high-speed recording prohibition management table. Deleted TOC information. Further, in response to the judgment by the high-speed recording prohibition judging means 25, the display control means 27 controls the display means 19 to display that the high-speed dubbing prohibition has been released. In each flowchart, “high-speed recording prohibited” means “high-speed dubbing prohibited”.

Referring to FIG. 2, in step S3, at the start of dubbing, the CD TO
Acquire C information. Then, the track number TNO of the track to be reproduced is set to 1 and the RTNO is set to 0, and the process proceeds to step S5. The RTNO is determined in step S7 described later.
Is the track number of the latest track for which the discrimination processing has been completed. In step S5, it is determined whether or not RTNO = TNO. That is, it is determined whether or not high-speed dubbing is permitted for the track (step S
It is determined whether or not 7) has been completed. If they are the same, the process proceeds to step S11; otherwise, the process proceeds to step S7.

In step S7, it is determined whether or not a track that matches the track number TNO of the track and the TOC information of the CD is in the high-speed recording prohibition management table. If so, the process proceeds to step S9; Proceed to S11. In a case where management is performed such that high-speed dubbing of all tracks of a CD including the track is prohibited within a predetermined time after high-speed dubbing of a certain track,
In the process of step S7, if none of the tracks included in the CD is in the high-speed recording prohibition management table, high-speed recording is permitted. If any of the tracks is in the high-speed recording prohibition management table, High-speed recording is prohibited for all tracks.

In step S9, the display control means 27 and the display means 19 display a message indicating that high-speed recording is prohibited, and the flow advances to step S10. In step S10, RTNO = T
NO is set, then TNO is incremented by 1, and the process proceeds to step S15. In step S11, recording on the MD by high-speed dubbing is started or high-speed recording is continued. Here, the recorded track number R
The value of TNO is made the same as the current track number TNO, and the process proceeds to step S13. The process in step S13 is
IS executed when high-speed dubbing operation is performed
This is a process for RC detection, and executes a process for starting a timer and creating a high-speed recording prohibition management table based on ISRC detected from digital audio data reproduced by the CD reproducing means 11. When the process is over, the process moves to a step S15.

The process of step S15 is a canceling process of high-speed recording prohibition (high-speed dubbing prohibition) and a display process.
The countdown of the running timer is executed according to the track number and the TOC information currently stored in the high-speed recording prohibition management table, and the timer corresponding to the timer whose timer value has become 0 has reached the timer time (74 minutes). The track number and the TOC information associated with the track number are deleted from the high-speed recording prohibition management table, and the display means 19 displays that high-speed dubbing prohibition has been released. Next, in step S17, are all tracks recorded? And did the user instruct recording end? Is determined, and if all the tracks have been recorded, or if the user has instructed the end of the recording, this flow ends, and otherwise, the process proceeds to step S5.

FIG. 4 is a flowchart showing an ISRC detection corresponding process according to the embodiment of the method of controlling the dubbing apparatus of the present invention, and corresponds to step S13 in the flowchart shown in FIG. In FIG. 4, at step S31, it is determined whether or not the reproduction of the track (current track) that has been reproduced until now has been completed. This discrimination processing is performed, for example, when the Q of the mode 1 inserted in the digital audio data input to the system control means 13.
This is performed by detecting a change in the track number (TNO) in the channel data. Then, when it is determined that the reproduction of the current track has been completed, Yes is determined, the process proceeds to step S33, and when the reproduction of the current track is not yet completed, No, the process proceeds to step S35.

In step S33, the value of TNO is set to 1
After that, the flow is terminated, and the routine goes to the processing of step S15 shown in FIG. On the other hand, step S
In step 35, the ISRC detecting means 21 determines whether or not the ISRC of the track being reproduced has been detected by the previous time. If the ISRC has been detected, the flow proceeds to step S15 shown in FIG. The process proceeds to step S37, and if not detected, the determination is No, and the process proceeds to step S37. Step S
In order to perform the process of 35, the ISRC detection means 21
When the ISRC of the track is detected for the first time, it is necessary to set a flag to that effect and hold this flag in the SRAM or the like.

In step S37, it is determined whether or not the ISRC of the track being reproduced is detected for the first time.
In this determination, the contents of the Q channel subcoding data (Q channel data in mode 3) inserted into the audio data of the track are referred to, and the ISR
C is detected. And if not detected, No,
This flow is ended, and the process proceeds to the process of step S15 shown in FIG. 2. If the detection is detected, the determination is Yes, and the process proceeds to step S41.

In step S41, it is checked whether or not there is a timer that is not currently being used. If there is, one timer is selected, a flag indicating that ISRC has been detected is set, and the flow advances to step S43. Finish the flow and Figure 2
The processing moves to the processing of step S15 shown in FIG. In the process of step S41, if there is no timer that is not currently used, the subsequent high-speed dubbing itself may be prohibited. In this case, if the timer time expires as time elapses from the timer started first and is cleared from the management table and there is an unused timer, the state where high-speed dubbing is possible is established. Will be restored.

In step S43, along with the timer ID of the selected timer, the track number of the track where ISRC is detected and the TOC information of the CD are associated with each other and stored in an unused area of the high-speed recording prohibition management table. Proceed to step S45. In step S45, title information and the like necessary for display are extracted from the memory storing the TOC information and the like. In the information extraction, title information is extracted from TOC information and text information (character information) read from the lead-in area of the CD and stored in the memory. If these are not recorded on the CD, the information necessary for display is extracted from the title information recorded on the UTOC of the MD. In Step S47, Step S
The timer selected in 41 is started, this flow is ended, and the routine goes to the processing of step S15 shown in FIG. The timer starts counting down from a timer time T (74 minutes), for example.

It is to be noted that the timing for starting the timer in step S47 may be such that the timer is started immediately after the determination processing in step S41. The determination process in step S41 and the timer activation process in step S47 may be shifted between step S31 and step S33, and the timer may be activated at the timing when the recording of the current track ends. In this case, if the predetermined timer time has not elapsed since the end of the recording of the current track,
Again, the same track as the current track cannot be dubbed at high speed.

As described above, for a track for which an ISRC is detected during high-speed dubbing, the track number of the track and the TOC information of the CD are stored in the high-speed recording prohibition management table, and at the same time, the 74 minutes Start the timer, count down the timer, and if high-speed dubbing of the same track is not performed within 74 minutes after the timer starts, display of "high-speed dubbing prohibition release" is permitted on the display device. This is performed together with the title information relating to the selected track and the like. In this display, SRA
It is displayed based on the title information stored in M or the like. Therefore, when title information is recorded on a CD,
The track number of D and the title information of the CD are displayed.
If no title information is recorded in the CD, the track number of the CD and the title information read from the MD are displayed.

If no title information is recorded on the CD or the MD, the title information input by the user is displayed together with the track number of the CD, or the TOC information of the CD including the track is displayed. indicate.
By doing so, even when the title information is not displayed, it becomes easy for the user to identify which information is the information whose high-speed dubbing prohibition has been canceled. TO to display here
The C information is at least the maximum track number and the total recording time of the CD, and the number of frames may be added to this. After the display of the high-speed recording prohibition (high-speed dubbing prohibition) release is started in step S27 shown in FIG. 3, it is necessary to continue the display for a time sufficient for the user to recognize or use the display. .

As described in detail above, according to the dubbing apparatus and the method of controlling the dubbing apparatus of the present invention, when reproducing information recorded on a CD and dubbing the recordable disc at a high speed, the dubbing is performed during the high-speed dubbing. When the ISRC of a certain track is detected from the reproduction signal of the CD, the track number of the track corresponding to the detected ISRC is associated with the TOC information of the CD including the track, and the information is stored in the high-speed recording prohibition management table. When determining whether or not to permit high-speed recording of a certain track to be subjected to high-speed dubbing, it is necessary to associate at least the track number and the track number stored in the high-speed recording prohibition management table. Information of the recorded CD, the track number of the track to be subjected to high-speed dubbing, and the T
By comparing the OC information with the OC information, it is determined whether or not recording of information to be subjected to high-speed dubbing is permitted.

Accordingly, whether high-speed recording of information to be subjected to high-speed dubbing is permitted or not is determined at the time of starting high-speed dubbing before recording is actually started. After recording up to that point, there is no situation in which the data must be erased again. Further, when the recording medium is a non-rewritable disc such as a CD-R, it is possible to prevent a useless recording area from being generated due to the management of high-speed recording prohibition. And for CDs for which ISRC is not detected,
Even when high-speed recording prohibition is not managed and high-speed dubbing is performed, its track number, TOC information, and the like are not stored in the high-speed recording prohibition management table. Therefore, even when the high-speed recording prohibition is managed using the TOC information, there is an effect that the danger of prohibiting the high-speed recording more than necessary can be avoided.
