And an A / D conversion unit 111. A /
The D conversion unit 111 is a detection unit 140 that detects temperature and humidity.
The amplifier 109 is connected to the speaker 120. The bus 110 is composed of a plurality of signal lines, and the bus 110 is used for data exchange between respective parts inside the audio reproducing device 100 and control of peripheral parts by the CPU 101.
Through. When the power (not shown) of the audio reproducing device 100 is turned off, the data recorded in the memory 102 is erased, but the data recorded in the recording unit 103 remains as it is, and the power of the audio reproducing device is turned on next time. It can be used if

The audio reproducing device 100 is a CD in which music is recorded in the CD drive 106, like the conventional CD reproducing device.
When D130 is set, music reproduction is started. The music recorded on the CD is played back by the CPU 10
1, a CD drive 106 and a digital processing unit 107
By controlling. CD drive 10
6 rotates the CD 130 and transfers the digital acoustic data to the digital processing unit 107 by an optical pickup (not shown). The digital processing unit 107 decodes the encoded digital data to generate stereo sound data of a predetermined number of bits, and transmits the stereo sound data to the D / A conversion unit 108. Stereo sound data is converted from a digital signal to an analog signal by the D / A conversion unit 108, amplified by the amplifier 109, and then transmitted to the speaker 120 to be reproduced as sound.

The operation unit 104 receives a user operation and outputs a signal for controlling reproduction of the CD 130 to the CPU.
101 is transmitted. The CPU 101 receives a signal from the operation unit 104, fast-forwards the song being reproduced, restores it,
Controls such as skipping and stopping playback.

The characteristic of the audio reproducing apparatus 100 is that the CPU 10
1 automatically determines a predetermined keyword in response to signals from the clock means 105, the detection unit 140, and the operation unit 104, and associates the determined keyword with the information for specifying the song being reproduced. , As a search table in the recording unit 103. Further, when determining the music to be played back, a keyword is automatically determined according to the signal from the timing means 105, the detection unit 140, etc., and the keyword is used to search the search cable of the recording unit 103 to match. The feature is to play the song.

FIG. 2 shows the CP in the process of automatically determining the keyword using the signal from the clock means 105.
7 is a flowchart showing a process performed by U101.
In the following description, the CD 130 is the CD drive 106
, And the TOC information is read from the CD 130 and recorded in the memory 102.

In step 201, it is repeatedly judged whether or not the music of the CD 130 is being reproduced. If it is judged that the music is being reproduced, the process proceeds to step 202.

In step 202, it is determined whether or not the TOC information recorded in the memory 102 has information (hereinafter, referred to as "song specifying information") for specifying the currently reproduced music. When it is determined that there is music specifying information corresponding to the music being reproduced, the music specifying information is acquired and stored in the memory 102.
Is recorded in a predetermined area, and if it is determined that there is no such area, the processing ends. For example, the MCN and the track number can be used as the music identification information. The MCN can specify the CD 130, and the track number indicates the order of the songs recorded on the CD 130.
And using the track number as a pair,
Even if the CD 130 is exchanged, the song can be specified.

In step 203, the clock means 105
The current date and time is acquired from the above and is recorded in a predetermined area of the memory 102.

In step 204, step 203
The information of the month and day is acquired from the current date and time acquired in step 3, and the keyword that matches the acquired month and day is displayed in (a) of FIG.
It is acquired from the "candidate table" shown in. In FIG. 3A, month and day are used as an index, and words related to annual events, holidays, anniversaries, seasons, etc. are recorded as keywords. For example, if the current day is July 7, two keywords “Tanabata” and “summer” are determined.

In step 205, step 204
Similarly, the time information is acquired from the current date and time acquired in step 203, and the keyword corresponding to the time zone including the acquired time is acquired from the candidate table shown in FIG. 3B. In FIG. 3B, the time zone is used as an index.

For example, the current time is December 24, 19:05.
If it is 0 minute, the keyword “Christmas Eve” is determined by the processing of step 204, and the keyword “evening” is determined by the processing of step 205.

In step 206, step 202
Song identification information acquired in step 204 and step 2
The keyword determined by the processing of 05 and the degree of importance are associated and recorded in the “search table” of the recording unit 103. An example of the search table is shown in FIG.

In FIG. 4A, the music identification information {M
A plurality of {keyword, importance} groups are recorded in association with the CN, track number} groups. The importance is
For example, an integer value can be used. When newly recording, “1” is recorded as the degree of importance. If the same song identification information has already been recorded, the song identification information is not recorded and only the keyword and the importance (= 1) are additionally recorded. Furthermore, when the same song identification information and the same keyword are recorded, the importance of the corresponding keyword is set to 1
Only increase.

In step 207, it is judged whether or not the reproduction of the next music piece is started. If it is judged that the reproduction of the next music piece is started, the process proceeds to step 202 and then step 2
The processing of 02 to 206 is repeated. When it is determined that the same song is being reproduced, it is determined whether a signal from the operation unit 104 has been received. When it is determined that the signal from the operation unit 104 is a signal corresponding to the music skip operation, the process proceeds to step 209.

In step 209, step 206
The importance of the keyword recorded in 1 is decreased by 1.

In step 210, it is judged whether or not there is an instruction to finish, and the process returns to step 207 until the termination instruction is given and the above processing is repeated.

As a result of the above, a search table in which the reproduced music identification information, keywords, and importance are recorded in association with each other is generated. The importance of the search table is
The greater the number of times the same song is played, the larger the value. If the user skips playback, the value will be smaller by that number. Therefore, as described later, the user listens to each song. Can be used as a desired measure.

Of the keywords in the candidate table shown in FIG. 3A, "graduation" on March 12th, "entrance" on April 5th, "marriage" on April 17th, and June 20th. "birthday"
Is data set by the user, and other data is set in advance. For example, the user can operate an operation button (not shown) such as a ten-key pad of the operation unit 104 to specify an arbitrary date, and register an arbitrary keyword.

FIG. 5 shows the CPU 10 in the process of determining the keyword according to the traveling speed of the automobile, as in FIG.
3 is a flowchart showing a process performed by 1.

In step 501, as a default setting, a predetermined value is set to the time interval Δt for detecting the traveling speed, 0 is set to the loop counter n, and the present time is set to T0.

In step 502, the current time is acquired from the time measuring means 105, it is compared with T0 to determine whether the time Δt has elapsed, and if it is determined that the time has elapsed, the process proceeds to step 503.

In step 503, the signal from the detector 140 is received via the A / D converter 111 to acquire the traveling speed, and the acquired speed is recorded in the memory 102 as the value of the variable V (n). At the same time, 1 is added to the counter n.

In step 504, the time variation of V (n) recorded in the memory 102 is evaluated. By repeating the processing of steps 502-510 as described later, the velocity data V (n) (n
= 1 to N, where N is the maximum number of speed data to be recorded) is recorded in the memory 102. In order to evaluate the time variation of V (n), for example, the variation width obtained by subtracting the minimum value from the maximum value of V (n) and the average value of V (n) are calculated.

In step 505, it is determined whether the fluctuation range calculated in step 504 is within a predetermined range. If it is determined to be within the predetermined range, step 5
If it is determined that the value is not within the predetermined range, the process proceeds to step 507.

In step 506, step 504
Using the average value calculated in, the candidate table is referenced and the corresponding keyword is determined. FIG. 3C shows an example of the candidate table. When (c) of FIG. 3 is used, the keyword “traffic jam” is used when the average speed is 0 to 5 km, and “slow” when the average speed is 5 to 20 km, 60
When the distance is more than km, the keyword is set to "fast", and in other cases (0 to 60 km), the keyword is not set. Further, similar to the process in step 206 (FIG. 2) described above, the music identification information being reproduced, the determined keyword, and the importance are recorded in the search table of the recording unit 103 in association with each other. The process when the same song identification information and the same keyword have already been recorded in the search table is the same as in step 206 (FIG. 2).

In step 507, the clock means 105
The current time is acquired from and set to T0.

In step 508, it is determined whether or not the number n of recording speeds detected by the counter n is exceeded. If it is determined that the speed is exceeded, an initial value 0 is set in the counter n in step 509. .

In step 510, it is judged whether or not there is an instruction to end, and the process returns to step 502 until the end instruction is given, and the above processing is repeated. As a result of the above processing, a search table similar to that shown in FIG. Further, similar to steps 208 and 209 (FIG. 2), it is possible to add a process of changing the degree of importance when the song being reproduced is affected by the operation unit.

It is also possible to determine the keyword to be attached to the music in accordance with the environment such as the weather. For example, a temperature sensor and a humidity sensor are used as the detection unit 140, these sensors are installed inside the vehicle, and signals from these sensors are acquired as digital data via the A / D conversion unit 111 at predetermined time intervals. To do. Using the acquired data, the discomfort index DI (%) can be calculated by, for example, Equation 1, and the result can be used to refer to a prepared candidate table to determine the corresponding keyword. DI = 0.81T + 0.01U (0.99T-14.3) +46.3 (Equation 1) where T is temperature (° C) and U is humidity (%).

FIG. 3D is an example of a candidate table in which the discomfort index and the keyword are associated with each other. As an index
It is also possible to use a combination of temperature and humidity values.

Further, it is possible to add an atmospheric pressure sensor to the temperature sensor and the humidity sensor and refer to a candidate table prepared in advance for the combination of these three types of sensors to determine the corresponding keyword.

It is also possible to add the number of passengers to the music as a keyword. In that case, the detection unit 14
A weight sensor is used for 0, it is embedded in the seat, and the number of passengers detected by the weight sensor is recorded for the search table in association with the music identification information being reproduced. For example, if the driver is riding alone, the song that you like to listen to,
When a passenger is present, information such as songs that he / she prefers to listen to can be reflected in the search table. Since the same song may be reproduced when the number of passengers is different, a plurality of passengers may be registered.

It is also possible to allow the user to directly input a keyword for each music piece from the operation unit 104 or select it from candidates. For example, the song identification information is obtained from the TOC information read from the CD and recorded in the recording unit 103, is displayed in a list on the display unit (not shown) as characters, and the user specifies a song to which a keyword is attached. After that, the keyword can be input as a character, can be input by voice, or can be selected from the keyword candidate list presented on the display unit.

It is also possible to determine a keyword to be attached to a song in accordance with the driver's state such as being sleepy. For example, using a CCD camera for the detection unit 140,
The driver's face is photographed, digital image data is obtained via the A / D converter 111, and the image is recorded in the memory 102 at predetermined time intervals. Image processing is performed on the recorded image data to detect the driver's eyes, and it is determined whether the driver is drowsy by analyzing the degree of opening and closing of the eyes, the time change pattern of opening and closing, etc. To do. If it is determined that the driver is drowsy, the driver may be drowsy by the song being played, or the song being played may not have the effect of awakening the driver from the drowsy state. From the above, the music specifying information being reproduced and the keyword “sleepiness” are recorded in the search table of the recording unit 103 in association with each other.

It is also possible to generate a search table by combining the plurality of keyword determination processes described above. FIG. 4B is an example of a search table generated using the current date, the current time, the traveling speed, the surrounding environment, the driver's awakening state, and the number of passengers.

The case where one search table is recorded in the recording unit 103 has been described above, but it is also possible to record it separately in a plurality of search tables. That is, after designating a search table for recording a keyword from a plurality of search tables to which identification information is added,
It is possible to play 130. In that case, the keyword and the music identification information determined by the above-described processing are recorded only in the designated search table.

It is also possible to employ a recording device (not shown) such as a removable semiconductor memory and record the search table in the recording device.

FIG. 6 is a block diagram showing an outline of an information providing apparatus according to the second embodiment of the present invention.

The information providing device 600 includes a CPU 101, a memory 102, a recording section 103, an operating section 104, and a clock means 1.
05, CD drive 106, digital processing unit 107,
D / A converter 108, amplifier 109, bus 110, speaker 120, CD 130, CD-ROM drive 60
1. A video memory (hereinafter referred to as “VRAM”) 602,
Video signal generator 603, GPS signal receiver 604, C
It is configured to include a D-ROM 610. The GPS signal receiving unit 604 is connected to the GPS antenna 620, and the video signal generating unit 603 is connected to the display unit 630.

The information providing device 600 is replaced with the A / D converter 111 in the audio reproducing device 100 shown in FIG.
It is equipped with means for realizing the car navigation function. 6, the same components as those in FIG. 1 are denoted by the same reference numerals, and these components are the audio reproducing device 100.
By performing the same function as, the sound recorded on the CD is reproduced.

CD-recording map information and related information
When the ROM 610 is set in the CD-ROM drive 601, the CPU 101 reads the map information and related information information and displays it on the display unit 630. CD-R
To read the map data recorded in OM610,
This is performed by the CPU 101 controlling the CD-ROM drive 601. CD-ROM drive 60
1 rotates the CD-ROM 610 and transfers digital map data to the memory 102 by an optical pickup (not shown). Next, two-dimensional map image data is generated from the map data recorded in the memory 102, and VR is generated.
Record in AM602. The video signal generator 603
The map and related information are displayed by reading out each pixel data of the map image data from the RAM 602, converting the pixel data into an analog video signal, and transmitting the analog video signal to the display unit 630.

Further, the CPU 101 has the GPS antenna 620 and the GPS signal receiving unit 604 at predetermined time intervals.
A GPS signal including transmission times transmitted from a plurality of artificial satellites is received via, and the distance to each artificial satellite is calculated from the time difference with the internal time measuring means 105. The position coordinates of the current vehicle are calculated using the calculated distance and the position information of the artificial satellite obtained from the orbit calculation of the artificial satellite, and the current position is set to the corresponding position of the map image data on the VRAM 602. By writing the predetermined graphic data to be displayed, a map on which a graphic representing the current position is superimposed is displayed on the display unit 630.

The information providing device 600 selects one from the candidate list of places that are classified and recorded in advance, like the ordinary car navigation device.
It has the function of setting the destination. For example, CD-R in advance
The CPU 101 hierarchically displays the candidates on the display unit 630 by using the table recorded in the OM 610, in which the large classification, the small classification, the name, the address, and the position coordinates are associated with each other, as shown in FIG. The destination is determined by the user selecting one of them. The CPU 101 records information on the determined destination in the recording unit 103, and displays a predetermined graphic representing the destination at the position on the map corresponding to the target position coordinates.

FIG. 8 shows the CPU in the process of determining a keyword from the set destination by the information providing device 600.
10 is a flowchart of a process performed by 101.

The process of determining a keyword from a destination will be described below with reference to the flowchart of FIG. It is assumed that the destination is set in advance and related information is recorded in the recording unit 103.

In steps 801, 802, the process shown in FIG.
The same processing as steps 201 and 202 is performed.

In step 803, information regarding the currently set destination is acquired from the recording unit 103.
For example, when the ABC ski resort is set as the destination from the candidates in FIG. 7, “ski resort” is acquired as the text data of the small classification.

In step 804, it is determined whether or not the acquired text data is included in the preset candidate table. If it is determined that it is included, the process proceeds to step 805 and it is included. If it is determined that there is not, the process proceeds to step 806.

In step 805, the applicable keyword is determined by referring to the candidate table. For example, in the case of the candidate table shown in FIG. 3E, “ski” is determined as the keyword. The decided keywords are
Similar to step 206 (FIG. 2), the music identification information being reproduced is associated with the importance and recorded in the search table of the recording unit 103.

The processing in steps 806 to 809 is the same as the processing in steps 207 to 210 in FIG. 2, and therefore its explanation is omitted here.

By the above processing, the retrieval table in which the keyword corresponding to the destination is recorded is generated for the music piece reproduced until the destination is reached.

It is also possible to determine the keyword according to the current position of the automobile. In this case, the map is divided into a plurality of blocks of a predetermined size in advance, a candidate table in which the block number assigned to each block and the keyword are associated with each other is created and recorded in the recording unit 103.

From the signals acquired via the GPS antenna 620 and the GPS signal receiving unit 604, the CPU 101
The current position (for example, latitude and longitude) is calculated, the block number of the block including this current position is determined, the keyword corresponding to the block number determined by referring to the candidate table is acquired, and the acquired keyword is The information is recorded in the search table in association with the piece of music identifying information being reproduced and the importance. As a result, for example, by using a candidate table in which a plurality of blocks near the coast are associated with the keyword "sea", when the position where the car is running is located within the block near the coast, the reproduction is being performed. It is possible to associate the song identification information for identifying the song, the keyword "sea", and the degree of importance with each other and record them in the search table.

Next, a description will be given of a process of determining a music piece to be reproduced by using the search table in the audio reproducing device 100 (FIG. 1) according to the first embodiment of the present invention.
The search table (for example, (b) in FIG. 4) is stored in the recording unit 103.
It is assumed that it is recorded in.

FIG. 9 is a flow chart showing a process performed by the CPU 101 in the process of automatically determining the music piece to be reproduced by using the keyword.

In step 901, as described above, after obtaining the information of the current date, the current time, the traveling speed, the temperature, the humidity, the number of passengers, and the awakening state of the driver, the keyword corresponding to each is determined.

In step 902, all the keywords determined for each of the current date, the current time, the traveling speed, the temperature, the humidity, and the number of passengers are included in the search table, and the keyword "sleepiness" is included. The song identification information (MCN and track number) not acquired is acquired.

At step 903, the number (k) of the acquired music specifying information is judged, and the process is branched according to the judgment result. If k = 0, the process proceeds to step 905, and k = 1
If so, the process proceeds to step 907, and if k ≧ 2, the process proceeds to step 906.

At step 904, the keyword is set to 1
After reducing by two, the process proceeds to step 904. Various types of processing are possible for this reduction processing. For example, it is possible to arbitrarily reduce, specify the order of reduction in advance in the keyword of the candidate table, and delete in the order corresponding to this.

In step 905, step 904
It is determined whether or not there are any keywords remaining by the processing of step 1. If it is determined that no keywords remain, the processing ends, and if it is determined that there are remaining keywords, the process returns to step 902, and the number has decreased from the previous time. Search the search table using keywords.

At step 906, one piece of music specifying information is selected from the plurality of pieces of music specifying information in consideration of the importance. Various kinds of processing are possible for this selection processing. For example, selecting the song specifying information including the highest importance, comparing the values obtained by adding all the importance corresponding to each song specifying information, and selecting the song specifying information corresponding to the highest value. It is possible. It is also possible to select the music identification information in consideration of the priority assigned to each keyword in advance. In this case, since the keywords used for the search correspond to all the selected song identification information, the keywords not used for the search among the keywords corresponding to the selected song identification information The priorities will be compared. In addition, character information (for example, MCN and track number of the song) corresponding to the selected song specifying information is displayed in a list on a display unit (not shown), and the user selects from the list to specify the song. It is also possible for the information to be determined.

At step 907, reproduction of the music recorded on the CD 130 corresponding to the determined music specifying information is started.

The processing in steps 908 to 911 is as follows.
This is similar to the processing in steps 207 to 210 of FIG. That is, when the operation unit is operated and an operation such as skipping or fast-forwarding is performed on the music being reproduced, the importance of the music identification information corresponding to the music being reproduced in the search table is decreased by one.

As described above, the music to be reproduced is automatically determined and reproduced by using the keyword automatically determined according to the current situation.

Also in the information providing apparatus 600 (FIG. 6) according to the second embodiment of the present invention, similarly, it is possible to automatically determine the music piece to be reproduced by using the keyword. That is, as described above, the keyword is automatically determined by using the set destination, current position, etc., and the song identification information corresponding to the keyword is acquired by referring to the search table, You can decide which song to play.

In the above, it has been explained that a set of {MCN, track number} can be used as an example of the music identification information, but a plurality of CDs may be sold as one set. In that case, the plurality of CDs may be sold. May all have the same MCN. In that case, since the song cannot be specified by the set of {MCN, track number}, information such as the start time and the playing time of each song in the TOC is used as the song specifying information. For example, a set of {MCN, track number, start time} or {MCN, track number, performance time} can be used as the music identification information.

Further, in the first embodiment shown in FIG. 1, the CD drive 106 is a drive whose data reading speed is faster than the sound reproducing speed, and the recording unit 103 is used.
In the data (acoustic data and TOC data) read at high speed from the CD, a high-capacity hard disk is used for the It is possible to record the acoustic data and the TOC data in the recording unit 103 while reading the acoustic data from the buffer at a speed suitable for the acoustic reproduction and reproducing the acoustic data. In the audio reproducing device having this configuration, it is possible to perform the above-described processing for automatically determining the keyword. In this case,
The sound data of each song is recorded in the recording unit 103 as a file with a non-overlapping file name, and the file name is used as the song identifying information, so that the TOC information is not used as the song identifying information. It is possible to directly associate the song and the determined keyword. Multiple CDs sold as a set as described above
Of the same MCN, or because there are CDs that do not have MCN, it may not be possible to specify the music by the music specifying information combined with the TOC information. By using the file name of the song as the song identification information, the song can be accurately identified.

In addition, the audio reproducing apparatus 100 shown in FIG.
It is also possible to configure with a serial interface for connecting to a mobile phone. In that case, by connecting a mobile phone, you can download additional information about the song (title, song description, singer, lyricist, composer, release date, etc.) from the server connected to the Internet and use it as song specific information. Correspondingly recorded in the recording unit 103, the additional information is searched using the keyword automatically determined as described above, and if there is a song that matches the keyword, the song can be reproduced. is there.

Further, in this case, it is possible to obtain the corresponding keyword from the candidate table (for example, (a) in FIG. 3) by using the release date of the song obtained from the server. Further, in step 907 (FIG. 9) in the process of determining the music to be reproduced, 1 is selected from the plurality of music identification information.
As a method of selecting one piece of music specifying information, it is possible to display a list of titles, singers, etc. corresponding to each piece of music specifying information so as to accept the user's selection.

Further, when the desired song data is downloaded from the server connected to the Internet via the mobile phone and is recorded in the recording unit 103, the recorded date and time is used, and step 203 in FIG. 2 is used. It is also possible to perform the same processing as that of steps 206 to 206 to determine the keyword and record it in the search table in association with the song identification information that identifies the downloaded song.

Although the case of using one CD has been described above, it is also possible to use a drive having an autochanger capable of mounting a plurality of CDs. Further, although the description has been made only with respect to the CD and the CD-ROM, the present invention is not limited to these and can be applied to a removable recording medium such as a DVD, an MD and the like.
