[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a dubbing device that performs high-speed dubbing from, for example, an MD (Mini Disc) to an MD or a CD (Compact Disc) to an MD based on the concept of an HCMS (Hi Speed Copy Management System), and an audio apparatus including the same. It is about.
[0002]
[Prior art]
With the revision of the standard for high-speed dubbing of MD, the dubbing speed limit for the integrated MD recording / reproducing machine has been removed, and high-speed dubbing has become possible. Currently, the concept of HCMS is recommended from the viewpoint of copyright protection. . According to the "Report on Revision of Standards for MD High-Speed Dubbing", HCMS is a system that prohibits high-speed dubbing of the same song for 74 minutes after the start of high-speed dubbing. In Japan, a rental service of a CD recording music is widely used, and when dubbing from an MD to an MD, it is necessary to protect the copyright in consideration of dubbing from the rental CD to the MD. Therefore, the concept of HCMS is recommended. It is considered that the above-mentioned dubbing inhibition time was set in consideration of the fact that the recordable time in the recording MD is 74 minutes.
[0003]
Here, FIG. 4 shows a schematic configuration of an HCMS device as a dubbing device considered as a conventional technique. The HCMS apparatus includes a high-speed dubbing execution unit 51, a song information writing unit 52, a date and time information writing unit 53, a holding unit 54, a song information search unit 55, a date and time information comparison unit 56, a dubbing execution control unit 57, a clock unit 58, and a backup unit. A battery 59 is provided.
[0004]
The high-speed dubbing execution unit 51 performs high-speed dubbing, and reads music information of a song to be dubbed at a high speed (hereinafter, referred to as a high-speed dubbing song) from an MD or CD as a dubbing source. The song information writing unit 52 writes the song information of the high-speed dubbed song into the holding unit 54. The date and time information writing unit 53 writes the date and time information when the high-speed dubbing is performed into the holding unit 54. The holding unit 54 is formed of, for example, a non-volatile memory, and holds the music information and the date and time information.
[0005]
The music information search means 55 searches the music information held by the holding means 54 for the music information read by the high-speed dubbing executing means 51, and the same music information is held in the holding means 54. It is determined whether or not. When the same piece of music information is stored in the storage unit 54, the date and time information comparison unit 56 stores the date and time information when the high-speed dubbing execution unit 51 is driven, and the same date and time stored in the storage unit 54. Is compared with the date and time information (date and time information when the song of the song information was previously subjected to high-speed dubbing) corresponding to the song information and the high-speed dubbing prohibition period (for example, 74 minutes).
[0006]
The dubbing execution control unit 57 controls the high-speed dubbing execution unit 51 to execute high-speed dubbing based on the search result of the music information search unit 55 and the comparison result of the date and time information comparison unit 56.
[0007]
The clocking means 58 is for clocking the date and time when high-speed dubbing is performed, and is connected to the backup battery 59. Thus, even if the power of the digital audio equipment including the HCMS device itself is turned off, the power supply from the backup battery 59 allows the clocking means 58 to continue clocking the date and time.
[0008]
In the above configuration, when the high-speed dubbing performing unit 51 is driven to start the high-speed dubbing, first, the high-speed dubbing performing unit 51 performs the music information of the high-speed dubbing tune recorded on the MD or CD of the dubbing source. Is read. Next, the song information search unit 55 searches the song information held by the holding unit 54 for the song information read by the high-speed dubbing execution unit 51, and the same song information is stored in the holding unit 54. Then, it is determined whether or not it exists in 54.
[0009]
If it is determined that the same song information does not exist in the holding unit 54, the song information search unit 55 determines that dubbing is possible, and the song information writing unit 52 determines whether or not the high-speed dubbing read by the high-speed dubbing performing unit 51. The music information is written into the holding means 54. At the same time, the date and time information writing unit 53 writes the date and time information at that time into the holding unit 54. Then, the dubbing execution control unit 57 causes the high-speed dubbing execution unit 51 to start high-speed dubbing from MD to MD or from CD to MD.
[0010]
On the other hand, when the same piece of music information is present in the holding means 54, the date and time information comparing means 56 determines the date and time information at the time when the high-speed dubbing execution means 51 is driven and the same piece of music information stored in the holding means 54. It is determined whether or not the difference from the date and time information corresponding to the period exceeds 74 minutes which is the high-speed dubbing prohibition period.
[0011]
If it is determined that the difference exceeds 74 minutes, the date and time information comparing means 56 determines that dubbing is possible, and the song information writing means 52 and the date and time information writing means 53 perform the same operation as described above to execute dubbing. The control unit 57 causes the high-speed dubbing execution unit 51 to start high-speed dubbing.
[0012]
On the other hand, if it is determined that the difference is within 74 minutes, the date and time information comparing unit 56 determines that dubbing is not possible, and the dubbing execution control unit 57 stops the high-speed dubbing by the high-speed dubbing executing unit 51.
[0013]
As described above, when the song information about the same song as the song that is to be dubbed at a high speed by the high-speed dubbing performing unit 51 is held in the holding unit 54, that is, the above-mentioned high-speed dubbing has performed high-speed dubbing in the past. In the case of dubbing of the same song as the song that has been played, high-speed dubbing of the same song within a predetermined time can be prohibited by checking the lapse of time from the date and time when high-speed dubbing was performed in the past.
[0014]
[Problems to be solved by the invention]
However, in the configuration shown in FIG. 4, for example, for the song X that was dubbed at high speed on the date and time A, if the date and time of the timer 58 were changed to, for example, (A + 74 minutes) or more by the user within 74 minutes when high-speed dubbing was prohibited. However, there is a problem in that the high-speed dubbing is permitted and the high-speed dubbing is permitted in a timely manner even though the high-speed dubbing is originally prohibited.
[0015]
Further, in the above configuration, it is necessary to constantly manage the time lapse from when high-speed dubbing is performed, and a backup battery 59 for driving the clocking means 58 is indispensable even when the power of the digital audio device itself is OFF. is there. For this reason, there is also a problem that power consumption is increased by requiring two power supplies of the digital audio device itself and the backup battery 59.
[0016]
The present invention has been made in order to solve the above-described problems, and has as its object to eliminate the need for a backup battery for timekeeping, and to allow a user to change the date and time information intentionally for a certain period of time even when the date and time information is intentionally changed. An object of the present invention is to provide a dubbing device capable of reliably prohibiting high-speed dubbing within a device, and an audio apparatus including the same.
[0017]
[Means for Solving the Problems]
The dubbing apparatus according to the present invention, in order to solve the above-described problem, reads song information for identifying a song recorded on a recording medium of the dubbing source, and performs high-speed dubbing performing means for performing high-speed dubbing; Clocking means for clocking, holding means for holding song information of songs that have been subjected to high-speed dubbing in the past and date and time information at that time, and the high-speed dubbing executing means among the song information held in the holding means The song information search means for determining whether high-speed dubbing is possible by searching for the song information read by the device, and the high-speed dubbing performing means is driven when the same song information is held in the holding means. A comparison is made between the difference between the first date and time information at the time and the second date and time information corresponding to the same piece of music information held in the holding means and the magnitude relationship between the high-speed dubbing prohibition period. Date and time information comparing means for judging whether high-speed dubbing is possible or not, and dubbing execution control means for controlling high-speed dubbing execution by the high-speed dubbing executing means based on the judgment results of the song information searching means and the date and time information comparing means. A dubbing device, wherein the date and time information changing means for changing the date and time measured by the time measuring means; and the high-speed dubbing is performed after the date and time are changed within a high-speed dubbing prohibition period for an arbitrary song. When the means is driven, a date and time information updating means for updating the second date and time information corresponding to the music to the changed date and time is further provided.
[0018]
According to the above configuration, when the high-speed dubbing execution unit is driven, the high-speed dubbing execution unit reads the song information of the song recorded on the recording medium (eg, MD or CD) of the dubbing source, and the song information searching unit reads the song information. The music information read by the high-speed dubbing executing means is searched from the music information already held in the holding means.
[0019]
Here, if the same song information as the song information does not exist in the holding unit, there is no high-speed dubbing prohibition period for the song, and the song information search unit determines that the high-speed dubbing of the song is not possible. It is determined that it is possible, and based on this determination, the dubbing execution control means causes the high-speed dubbing execution means to execute high-speed dubbing.
[0020]
On the other hand, if the same piece of music information exists in the holding means, the date and time information comparing means compares the first piece of date and time information with the second piece of date and time information corresponding to the same piece of music information held in the holding means. Is compared with a high-speed dubbing prohibition period (for example, 74 minutes) to determine whether high-speed dubbing is possible or not.
[0021]
For example, if the difference between the two pieces of information exceeds the high-speed dubbing prohibition period, even if high-speed dubbing is performed, no two identical songs exist within the high-speed dubbing prohibition period. The means determines that high-speed dubbing of the music is possible, and based on this determination, the dubbing execution control means causes the high-speed dubbing executing means to execute high-speed dubbing.
[0022]
Conversely, if the difference between the two information is within the high-speed dubbing prohibition period, if high-speed dubbing is performed, there will be two identical songs within the high-speed dubbing prohibition period, which violates the concept of HCMS. Therefore, the date and time information comparing means determines that high-speed dubbing of the music is impossible, and based on this determination, the dubbing execution control means stops high-speed dubbing by the high-speed dubbing executing means.
[0023]
As described above, the dubbing execution control unit controls the execution of the high-speed dubbing based on the determination results of the song information search unit and the date and time information comparing unit, so that the HCMS that inhibits the high-speed dubbing of the same song within the high-speed dubbing prohibition period is provided. Can be provided.
[0024]
Here, in the above configuration, when the high-speed dubbing execution unit is driven after the time and date is changed by the date and time information changing unit within the high-speed dubbing prohibition period for an arbitrary song, the above-mentioned song is changed by the date and time information updating unit. Is updated to the changed date and time. If the change of the date and time is, for example, a reset of the date and time information changing means or the clocking means by turning off the power of the apparatus, the second date and time information is updated to, for example, 0:00 on the same day (the reset is performed). ).
[0025]
In this case, the date and time information comparing means determines whether or not high-speed dubbing is possible based on the magnitude relationship between the difference between the first date and time information and the changed date and time and the high-speed dubbing prohibition period. Since the first date and time information is temporally later than the changed date and time, as a result of the above determination, high-speed dubbing is prohibited during the high-speed dubbing prohibition period from the changed date and time. It is possible to do.
[0026]
Therefore, according to the above configuration, even if high-speed dubbing is performed on an arbitrary song and then the device is illegally used (intentionally changing the date and time or resetting) within the high-speed dubbing prohibition period, the device can be used within the high-speed dubbing prohibition period. High-speed dubbing of the same music as the above-mentioned music can be surely prohibited, and high-speed dubbing faithful to the concept of HCMS can be realized.
[0027]
Further, when the date and time are changed, the second date and time information is updated by the date and time information updating means, so that it is not necessary for the timing means to always keep the correct date and time. As a result, even when the dubbing apparatus of the present invention is applied to a digital audio device, a backup battery for supplying power to the timer when the power of the device is turned off can be eliminated. As a result, power consumption can be reliably reduced as compared with the related art in which the backup battery is considered necessary.
[0028]
In order to solve the above-mentioned problem, the dubbing device according to the present invention, when the date and time are not changed within the high-speed dubbing prohibition period for an arbitrary song, sets the high-speed dubbing prohibition period. After a lapse of time, the music information of the music stored in the holding means is deleted.
[0029]
After the high-speed dubbing is started for any song, if the date and time are not changed within the high-speed dubbing prohibition period for the song, if the high-speed dubbing prohibition period elapses, the same song as the above song High-speed dubbing is possible, and it is no longer necessary to hold the music information on the music in the holding means. Therefore, according to the above configuration, by deleting song information that is unnecessary for determining whether high-speed dubbing is possible or not, it is not necessary to configure the holding unit with a large memory capacity, and the cost of the holding unit and thus the cost of the device are reduced. Can be reduced.
[0030]
In order to solve the above problem, the dubbing device according to the present invention, wherein the date and time information updating means resets the second date and time information when the date and time information changing means resets the date and time. Features.
[0031]
According to the above configuration, when the second date and time information is reset by the date and time information updating unit, the date and time information comparing unit determines whether the difference between the first date and time information and the reset time and the high-speed dubbing prohibition period are large or small. Since high-speed dubbing is determined based on the relationship, high-speed dubbing can be prohibited during the high-speed dubbing prohibition period from the time of reset. Therefore, even when the date and time are reset within the high-speed dubbing prohibition period, high-speed dubbing faithful to the concept of HCMS can be realized.
[0032]
In order to solve the above-mentioned problem, the dubbing device according to the present invention, wherein the date and time information updating means resets the second date and time information when the date and time are reset by turning off the power of the device. Features.
[0033]
According to the above configuration, when the date and time are reset by turning off the power of the apparatus, the date and time information comparison unit determines the date and time information based on the difference between the first date and time information and the reset time and the high-speed dubbing prohibition period. It is determined whether high-speed dubbing is possible. Further, since the time and date of the clock means are reset by turning off the power of the apparatus, the first date and time information is measured from the moment when the power is turned on next. Thus, when it is determined whether high-speed dubbing is possible or not based on the difference between the first date and time information and the reset time and the high-speed dubbing prohibition period, the high-speed dubbing prohibition period starts immediately after the power is turned on. During this time, high-speed dubbing can be prohibited. Therefore, according to the above configuration, even when the power is turned off during the high-speed dubbing prohibition period, high-speed dubbing faithful to the concept of HCMS can be realized.
[0034]
According to another aspect of the invention, an audio apparatus includes any one of the above-described dubbing apparatuses.
[0035]
According to the above configuration, the dubbing device realizes high-speed dubbing faithful to the concept of HCMS even when the device is illegally used within the high-speed dubbing prohibition period for an arbitrary song. By incorporating the in the audio device, the convenience can be reliably provided to the customer through the product of the audio device.
[0036]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of the present invention will be described below with reference to the drawings. The HCMS device as a dubbing device according to the present invention is a device that can perform high-speed dubbing from MD to MD, and is mounted on digital audio equipment. This digital audio device includes an AM / FM tuner, a cassette deck, a CD playback unit, a speaker, and the like, in addition to the HCMS device described above. Hereinafter, the HCMS device will be described in detail.
[0037]
As shown in FIG. 1, the HCMS apparatus includes a high-speed dubbing executing unit 1, a song information writing unit 2, a date and time information writing unit 3, a holding unit 4, a song information searching unit 5, a date and time information comparing unit 6, a dubbing execution control unit. 7 and timing means 8.
[0038]
The high-speed dubbing executing means 1 records contents (for example, music) recorded on one MD (recording medium) on the other MD at high speed, that is, performs high-speed dubbing. The high-speed dubbing is performed, for example, at twice the speed (twice the speed during normal dubbing). For example, if the first song of an MD containing 20 three-minute songs (3 × 20 = 60 minutes) was dubbed at 10:00 at high speed, the high-speed dubbing end time of the 20th song is 10:30. The dubbing speed at the time of high-speed dubbing is not limited to the above-mentioned double speed, but may be another speed such as triple speed.
[0039]
When the high-speed dubbing execution unit 1 is turned on, the high-speed dubbing execution unit 1 performs music information (for example, song identification information) for identifying the high-speed dubbing music recorded on the MD of the dubbing source before starting the high-speed dubbing. The song title, song length, etc.) are read for all recorded high-speed dubbed songs.
[0040]
The song information writing unit 2 writes, in the holding unit 4, the song information of the music that has been subjected to the high-speed dubbing, out of the song information read by the high-speed dubbing performing unit 1. The date and time information writing means 3 writes the date and time information at the time of high-speed dubbing to the holding means 4. The date and time information is managed by a clock unit 8 or a date and time information updating unit 10 described later. The holding means 4 holds the music information of the music that has been subjected to high-speed dubbing in the past and the date and time information at that time as a set, and is composed of, for example, a nonvolatile memory that stores 8 bytes per music.
[0041]
The music information search means 5 searches the music information (songs that have been previously high-speed dubbed) held in the holding means 4 for the music information read by the high-speed dubbing executing means 1 and stores the music information in the holding means 4. It is determined whether the same music information is held. The song information search means 5 determines that dubbing is possible without the same song information. However, if the same song information is present, the song information searching means 5 does not immediately determine that dubbing is not possible. Entrust.
[0042]
The date and time information comparing means 6 outputs the date and time information at the time of driving the high-speed dubbing execution means 1 when the same music information as the music information read by the high-speed dubbing execution means 1 is held in the holding means 4. Hereinafter, referred to as first date and time information) and date and time information corresponding to the same piece of music information stored in the holding unit 4 (date and time information at the time of high-speed dubbing in the past; hereinafter, second date and time information) ) To determine whether dubbing is possible. Specifically, when the difference between the first date and time information and the second date and time information exceeds the high-speed dubbing prohibition period, the date and time information comparing means 6 determines that dubbing is possible. Is within the above-mentioned predetermined time, it is determined that dubbing is not possible.
[0043]
The high-speed dubbing prohibition period is a period that is set based on the concept of HCMS and prohibits high-speed dubbing of the same song. For example, in the case of MD, the recordable time of 74 minutes corresponds to this. I do.
[0044]
The dubbing execution control unit 7 controls the execution of high-speed dubbing by the high-speed dubbing execution unit 1 based on the determination results of the music information search unit 5 and the date and time information comparison unit 6. In other words, when the song information search means 5 or the date / time information comparison means 6 determines that dubbing is possible, the dubbing execution control means 7 causes the high-speed dubbing execution means 1 to execute high-speed dubbing while the date / time information comparison means If it is determined in step 6 that dubbing is impossible, high-speed dubbing by the high-speed dubbing executing means 1 is stopped.
[0045]
The timer 8 manages time information by measuring the date and time, and is composed of, for example, a clock. The time information measured by the timer 8 is input to the date / time information changer 9 described later in addition to the date / time information writer 3 and the date / time information comparator 6. In the present embodiment, since the backup battery of the timekeeping means 8 is not provided, when the power of the HCMS device is turned off, that is, when the power of the digital audio device itself is turned off, the timekeeping of the timekeeping means 8 is, for example, the same day. The clock is reset to 0:00, and the clocking of the clocking means 8 is restarted at the same time when the power is turned on.
[0046]
Next, the operation of the HCMS device having the above configuration will be described with reference to FIG.
[0047]
First, when the high-speed dubbing execution unit 1 is driven to start high-speed dubbing, the high-speed dubbing execution unit 1 reads all the music information of the high-speed dubbing music from the MD of the dubbing source (step 1; Simply abbreviated as S).
[0048]
Subsequently, the music information search means 5 searches the music information stored in the holding means 4 for the music information read by the high-speed dubbing executing means 1, and the same music information is stored in the storage means 4. Is determined (S2).
[0049]
If it is determined in S2 that the same piece of music information does not exist, the piece of music information searching means 5 determines that dubbing is possible (S3), and the piece of music information writing means 2 reads the high speed data read by the high speed dubbing executing means 1. While the song information of the dubbed song is written into the holding unit 4, the date and time information writing unit 3 writes the date and time information at that time into the holding unit 4 (S4). Then, the dubbing execution control means 7 starts the high-speed dubbing by the high-speed dubbing execution means 1 (S5).
[0050]
On the other hand, if it is determined in S2 that the same piece of music information is present in the holding unit 4, the date / time information comparing unit 6 sets the first date / time information at the time of driving the high-speed dubbing execution unit 1 and the holding unit 4 Is compared with the difference between the second date and time information corresponding to the same piece of music information and the high-speed dubbing prohibition period (S6).
[0051]
In S6, if it is determined that the difference between the two exceeds the high-speed dubbing prohibition period, the date and time information comparing means 6 determines that dubbing is possible, and proceeds to S3 to perform the same processing as described above. On the other hand, if it is determined in S6 that the difference between the two is within the high-speed dubbing prohibition period, the date / time information comparing means 6 determines that dubbing is not possible (S7), and the dubbing execution control means 7 sets the high-speed dubbing control. The high-speed dubbing by the implementation means 1 is stopped.
[0052]
According to the above configuration, when the song information about the same song as the song to be dubbed at high speed is held in the holding unit 4, unless the predetermined time has elapsed since the start of the high-speed dubbing of the same song, the high-speed dubbing is performed. No dubbing is performed. Therefore, high-speed dubbing faithful to the concept of HCMS in which digital high-speed dubbing of the same music within a predetermined time is prohibited can be realized. As a result, convenience can be reliably provided to the customer through a product called digital audio equipment.
[0053]
Next, features of the present invention will be described. As shown in FIG. 1, the HCMS device of the present invention further includes a date / time information changing unit 9 and a date / time information updating unit 10 in addition to the above configuration.
[0054]
The date and time information changing means 9 changes (including resetting) the date and time measured by the time measuring means 8. For example, if the time and date measured by the timekeeping means 8 deviate from the official date and time, the user can correctly reset the time and date by the time and date information changing means 9.
[0055]
The date and time information updating unit 10 changes the time when the high-speed dubbing execution unit 1 is driven after the time and date is changed by the date and time information changing unit 9 during the high-speed dubbing prohibition period for an arbitrary song. The corresponding second date and time information is updated (overwritten) to the date and time after the change. If the change is a reset of the timekeeping means 8 by the date and time information changing means 9, the date and time information updating means 10 resets the second date and time information (updates to 0:00 on the same day).
[0056]
The date and time information updating means 10 is set so as to reset the second date and time information even when the power of the HCMS device is turned off, that is, when the power of the digital audio device itself is turned off.
[0057]
In the above configuration, assuming that the time keeping by the time keeping means 8 is continued in S11 of FIG. 3, the date and time information updating means 10 determines whether or not the date and time have been changed (S12). If there is no change in the date and time in S12, the second date and time information held in the holding unit 4 is not changed by the date and time information updating unit 10 (S13).
[0058]
On the other hand, in S12, if there is a change in the date and time, the date and time information updating means 10 overwrites the second date and time information with the date and time after the change, and if the date and time is reset, the date and time information The updating unit 10 resets the second date and time information to 0:00 on the same day (S14). Thereby, the content (second date and time information) held by the holding unit 4 is changed (S15).
[0059]
According to the above configuration, when the date and time of the timekeeping means 8 is changed, the second date and time information is updated to the date and time after the change. Therefore, in S6 of FIG. Whether high-speed dubbing is possible or not is determined based on the date and time after the change. Specifically, in S6, if the difference between the first date and time information and the changed date and time is within a predetermined time (for example, within 74 minutes), it is determined that dubbing is not possible (S7), and the difference is determined by the predetermined date and time. If the time has passed, it is determined that dubbing is possible (S3).
[0060]
That is, by the above update, the starting point of the 74-minute high-speed dubbing prohibition period is not the date and time (second date and time) when dubbing was performed for the same song in the past, but the date and time after the change. Therefore, no matter how the date and time of the clock means 8 is changed, high-speed dubbing can be prohibited for 74 minutes after the change.
[0061]
The same applies to the case where the date and time of the timekeeping means 8 is reset. By resetting the second date and time information, high-speed dubbing can be prohibited for 74 minutes after the reset.
[0062]
Therefore, in the above configuration, even after the high-speed dubbing of a certain song is performed, for example, if the device is illegally used (intentionally changing the date and time or resetting) within 74 minutes, the high-speed dubbing prohibition period, which is the concept of HCMS, is not used. , The prohibition of high-speed dubbing of the same music as the above music can be surely executed without violating the rules.
[0063]
When the power of the digital audio equipment is turned off and the HCMS device is turned off, the date and time information updating means 10 not only resets the second date and time information, but also keeps the time of the The timer is reset by itself, and the clocking of the clocking means 8 starts simultaneously with the turning on of the power supply. As a result, the starting point of the 74-minute high-speed dubbing prohibition period is the time when the power is turned on. Therefore, even if the power of the digital audio device is turned off within 74 minutes after the high-speed dubbing of a certain song, the high-speed dubbing can be prohibited for 74 minutes after the power is turned on. Prohibition of high-speed dubbing based on the above can be surely executed.
[0064]
Further, since the date and time information updating means 10 for updating the second date and time information when the date and time of the clocking means 8 is changed is provided, it is not necessary for the clocking means 8 to always keep the correct date and time. This eliminates the need for a backup battery for supplying power to the clock unit 8 when the digital audio device is turned off, thereby reducing power consumption. In addition, since the time can be managed using only the power supply of the digital audio device, the HCMS device can be operated efficiently.
[0065]
In other words, the HCMS apparatus of the present invention includes a high-speed dubbing executing unit 1 for performing high-speed dubbing, a timekeeping unit 8 for managing date and time information, song information for identifying high-speed dubbed music, and date and time information for performing high-speed dubbing. , A song information search unit 5 for searching for song information subjected to high-speed dubbing, and a date / time information comparing unit 6 for comparing date / time information for high-speed dubbing with the held date / time information. A dubbing execution control means 7 for disallowing high-speed dubbing under certain conditions; and a date and time corresponding to the held high-speed dubbed music when the timekeeping means 8 is initialized or changed. The above effects can be obtained by providing the date and time information updating means 10 for initializing the information or overwriting the changed date and time information.
[0066]
In the present embodiment, high-speed dubbing of a certain song X is started at, for example, date and time A, and the above-mentioned date and time A is changed within the period of prohibition of high-speed dubbing of song X (reset by the date and time information changing means and device power-off). (Including resetting of the song), after the prohibition period of the high-speed dubbing has elapsed, that is, after the date and time (A + 74 minutes), the song information on the song X held in the holding means 4 and the song information are corresponded. The holding means 4 is set so that the second date and time information to be deleted is deleted.
[0067]
For example, assuming that the high-speed dubbing start time of the song X is 10:00, for example, the power of the digital audio device is continuously ON until 11:14, and if the date and time are not changed, the digital audio device is thereafter stored in the storage unit 4. The music information of the music piece X and the second date and time information corresponding to the music information are automatically deleted. This enables high-speed dubbing of the music piece X from the same MD again from 11:15.
[0068]
In this way, by deleting the song information that is not necessary for determining whether or not high-speed dubbing is possible, the holding unit 4 does not need to be configured with a large memory capacity. Therefore, the cost of the holding means 4 and thus the device can be reduced.
[0069]
When the holding unit 4 is set as described above, if the date and time is not changed within the high-speed dubbing prohibition period, whether the song information on the same song as the high-speed dubbing song is held in the holding unit 4 is determined. Only by the song information search means 5, it is possible to determine whether or not high-speed dubbing is possible for the same song. Therefore, in this case, it is possible to omit the step S6 in FIG.
[0070]
In the above, the HCMS device that performs dubbing from MD to MD has been described. However, the HCMS device of the present invention can be applied to, for example, dubbing from CD to MD and from CD to CDR or CDWR.
[0071]
【The invention's effect】
As described above, the dubbing device according to the present invention has the date and time information changing means for changing the date and time being timed by the time measuring means, and the date and time has been changed within the prohibited period of high-speed dubbing for any music. After that, when the high-speed dubbing execution unit is driven, a date and time information updating unit that updates the second date and time information corresponding to the music to the changed date and time is further provided.
[0072]
Therefore, the date and time information comparison means determines whether or not high-speed dubbing is possible based on the difference between the first date and time information and the changed date and time and the high-speed dubbing prohibition period. During the high-speed dubbing prohibition period from the date and time after the change, high-speed dubbing can be prohibited.
[0073]
Therefore, according to the above configuration, even if high-speed dubbing is performed on an arbitrary song and then the device is illegally used (intentionally changing the date and time or resetting) within the high-speed dubbing prohibition period, the device can be used within the high-speed dubbing prohibition period. High-speed dubbing of the same music as the above-mentioned music is surely prohibited, so that high-speed dubbing faithful to the concept of HCMS can be realized.
[0074]
Further, when the date and time are changed, the second date and time information is updated by the date and time information updating means, so that it is not necessary for the timing means to always keep the correct date and time. As a result, even when the dubbing apparatus of the present invention is applied to a digital audio device, a backup battery for supplying power to the timer when the power of the device is turned off can be eliminated. As a result, there is an effect that power consumption can be surely reduced as compared with the related art in which the backup battery is considered to be necessary.
[0075]
As described above, the dubbing apparatus according to the present invention, as described above, the holding unit, when the date and time is not changed within the high-speed dubbing prohibition period for any song, after the high-speed dubbing prohibition period has elapsed, This is a configuration in which song information on the song stored in the holding unit is deleted.
[0076]
Therefore, by deleting music information unnecessary for determining whether high-speed dubbing is possible or not, it is not necessary to configure the holding unit with a large memory capacity. As a result, there is an effect that the cost of the holding means and thus the device can be reduced.
[0077]
As described above, the dubbing apparatus according to the present invention is configured such that the date and time information updating means resets the second date and time information when the date and time information changing means resets the date and time.
[0078]
Therefore, when the date and time information updating means resets the second date and time information, the date and time information comparing means sets the high speed dubbing based on the difference between the first date and time information and the reset time and the high speed dubbing prohibition period. Is determined, the high-speed dubbing can be prohibited during the high-speed dubbing prohibition period from the time of resetting. Therefore, even when the date and time are reset during the high-speed dubbing prohibition period, high-speed dubbing faithful to the concept of HCMS can be realized.
[0079]
As described above, the dubbing device according to the present invention has a configuration in which the date and time information updating means resets the second date and time information when the date and time are reset by turning off the power of the device.
[0080]
Therefore, when the date and time is reset by turning off the power of the apparatus, the date and time information comparing means determines whether high-speed dubbing is possible or not based on the magnitude relationship between the difference between the first date and time information and the reset time and the high-speed dubbing prohibition period. Will be determined. Since the time and date of the time measuring means are reset by turning off the power of the apparatus, the first date and time information is measured from the moment when the power is turned on. Thus, when it is determined whether high-speed dubbing is possible or not based on the difference between the first date and time information and the reset time and the high-speed dubbing prohibition period, the high-speed dubbing prohibition period starts immediately after the power is turned on. During this time, high-speed dubbing can be prohibited. Therefore, according to the above configuration, even when the power is turned off during the high-speed dubbing prohibition period, high-speed dubbing faithful to the concept of HCMS can be realized.
[0081]
As described above, the audio device according to the present invention is configured to include any of the above-described dubbing devices.
[0082]
Therefore, there is an effect that the convenience can be reliably provided to the customer through a product called an audio device including the dubbing device.
