Description

The present invention relates to a playlist creation device and a song playback device, and more particularly to a playlist creation device for creating a playlist of songs and a song playback device that plays songs according to the playlist.

It is preferable that the music listened to in the passenger compartment should be something that the driver or passenger wants to listen to or like for the driver to drive comfortably or to make the driving fun. Therefore, audio devices that provide music that matches the preferences of the driver and the mood at that time have been proposed (for example, see Patent Documents 1 and 2 below). Japanese Patent Application Laid-Open No. 2004-228688 analyzes audio preference based on past listening results, selects music that matches the driver's preference based on the analysis result, and provides the selected music to the driver An apparatus is disclosed.

However, it is not easy to analyze the preferences with high accuracy, and there is a possibility that there are many cases where the driver wants to listen to music that is not correctly selected. In addition, when selecting music that matches the driver's preference, it is highly likely that the same music is selected every time, and there is a high possibility that only music that is tired of listening will be provided.

Also, the music you want to listen to may change depending on your mood, and you may not want to listen to the song you wanted to hear today, or vice versa. I might want to listen to the song I had tomorrow. Therefore, the music that the user wants to listen to is the user's occasional mood, etc., and may be preferably selected by the user himself / herself.

However, if the user has to select all the songs, the operation becomes troublesome. In particular, mass storage devices such as HDD (Hard Disk Drive) have become popular recently.
Data related to a large number of songs (for example, 1000 songs) can be stored, but it is not easy to select a desired song from among 1000 songs.

For example, recently, as shown in FIG. 20, the data of the music itself recorded on CD2-1 to CD2-n (hereinafter referred to as music data) and TOC (Table Of Con) are stored in HDD1.
tents) information (for example, the number of songs and total performance time), and further information related to the CD (
For example, the title name, the number of recorded songs, the total performance time of the recorded songs, the singer name, the song name / performance time of each song) are stored.

The music data and TOC information may be read from CD2-1 to CD2-n and stored in the HDD 1. Since there is a service institution 3 that provides information on the CD, the service institution 3 The provided information may be acquired and stored in the HDD 1. It can be determined from the number of recorded songs and the total performance time whether the information on the CD provided by the service organization 3 corresponds to which song data is stored in the HDD 1. The first information stored on the CD whose title name is “Large Invention” (16 songs, total performance time 51 minutes 12 seconds) is the second stored song data (CD2). 2 can be determined to correspond to the music data recorded in -2.

By the way, if the number of songs selected by the audio device as described in Patent Documents 1 and 2 is too large, there is a possibility that a song desired by the user may not be played back during the drive despite being selected. There is.

For example, if the time required to reach the destination is 60 minutes, the predetermined range is set to 60 minutes, or the predetermined time is set so that the performance ends a little before reaching the destination. Can be set to 55 minutes (5 minutes ago), or the predetermined range can be set to 54 minutes (90%). As a result, it is possible to prevent a situation in which a song that is scheduled to be played is not played during driving.

In addition, the music playback device (5) according to the present invention includes a time required for completion of playback of the music included in the playlist in any of the music playback devices (1) to (4), and the mobile unit. And a processing means for performing a predetermined process relating to the reproduction of the music based on the reproduction status of the music, which is obtained based on the expected time required to reach the destination.

By the way, for example, if the vehicle is moving smoothly and the destination is reached earlier than planned because the road is empty or there are few stops due to traffic lights, the song that was scheduled to be played is driven There is a risk that it will not be regenerated inside. On the other hand, if the vehicle does not move smoothly because the road is crowded or there are many stops due to traffic lights, etc., if the arrival at the destination is behind schedule, the arrival at the destination There is a risk that the playback of the music will end much earlier than before.

According to the music playback device (5), the playback status of the music (for example, the situation where the destination has been reached earlier than planned and the music that was scheduled to be played may not be played during driving). Or, conversely, the arrival of the destination is behind schedule and there is a possibility that the reproduction of the song may end well before the arrival of the destination) Predetermined processing relating to reproduction is performed. As a result, for example, when the destination has been reached earlier than planned, a message such as “Please proceed a little more slowly” is played, and the planned song is not played during the drive. It can be avoided.

In the music playback device (6) according to the present invention, in the music playback device (5), playback of the music included in the playlist is not completed before the mobile body reaches the destination. If the situation is present, the processing means may perform one of an increase in the playback speed of the music, a shortening or cut of the waiting time between the music, and a cut or fade-out of the end part of each music. Yes.

According to the music reproducing device (6), a situation occurs in which the music that is scheduled to be reproduced is not reproduced during the drive, for example, because the mobile body reaches the destination earlier than planned. If there is a possibility, the reproduction speed of the music is increased, the waiting time between each music is shortened or cut, and the end part of each music is cut or faded out. As a result, it is possible to avoid a situation in which a planned music piece is not reproduced during driving.

In addition, the music playback device (7) according to the present invention is included in the playlist in the music playback device (5) or (6) at least a predetermined time before the mobile body reaches the destination. When the playback of the current music is completed, the processing means performs one of a decrease in the music playback speed, an extension of the waiting time between the music, and a repeat of the last part of each music. It is characterized by being.

According to the music reproducing device (7), the reproduction of the music is completed much earlier than the arrival at the destination because the arrival of the moving body at the destination is slower than planned. If there is a possibility that the music will be played, any one of a decrease in the reproduction speed of the music, an extension of the waiting time between the music, and a repeat of the last part of each music are performed. As a result, it is possible to avoid a situation in which the reproduction of the music ends much before the arrival at the destination.

The music playback device (8) according to the present invention is used by being mounted on a moving body such as a vehicle. The music playback device (8) selects a music from the music to be selected, and plays a music playlist. At least one of the second music playback means for playing back music and the playlist created by the fourth play list creation means according to the play list created by the fourth play list creation means The music introduction means is controlled so as to differentiate the introduction based on the music introduction means for introducing the music to the user and the degree to which the mobile body can be played before reaching the destination. And an introduction control means.

By the way, since the time when the music can be listened to is limited, the music that is scheduled to be played (that is, the music included in the playlist) is within the time (for example, driving until reaching the destination). There is a risk that it will not be regenerated. In particular, the time required to reach the destination tends to be longer or shorter due to road congestion, the number of stops due to signals, and the like.

Therefore, at the time of starting playback of a song according to the playlist, even if all the songs included in the playlist are scheduled to be played before reaching the destination, the destination is reached. If it becomes early, the planned music is left without being played.

According to the music playback device (8), since at least unplayed music is introduced to the user in the play list, the user says that there are still more music left to be played. And which songs are not being played. Further, the introduction can be differentiated based on the degree to which the mobile body can be reproduced before reaching the destination.

For example, if the time required to reach the destination is 20 minutes, the remaining 4 songs are introduced as reproducible (calculated as 5 minutes / 1 song), and the subsequent songs are considered difficult to play. Introduced. When the time required to reach the destination is 15 to 20 minutes, the remaining three songs are introduced as reproducible (blue display), and the next song is introduced as a reproduction subtlety ( (Displayed in yellow), and subsequent songs are introduced as difficult to play (displayed in red). Thereby, the user can grasp during the drive the music that will be played, the delicate music that will be played or the music that will not be played.

Further, the music playback device (9) according to the present invention includes a third environment setting means for setting an environment in which the user can change the playback order of the unplayed music in the music playback device (8). And when the reproduction order is changed in the environment set by the third environment setting means, the second music reproduction means reproduces the music according to the changed reproduction order. It is said.

According to the music playback device (9), since the user can freely change the playback order of unplayed music, the music that is expected to be subtle or difficult to play is preferentially played. Will be able to. As a result, it is possible to avoid a situation in which the user's favorite song, which is located in the second half of the playback order, remains without being played back.

Processing operations performed by the microcomputer 12 (the audio control unit 13) in the audio device 11 configured to include the playlist creation device and the music playback device according to the embodiment (1) [1.
-1] will be described based on the flowchart shown in FIG. This processing operation [1-1
] Is an operation performed when the power of the audio apparatus is turned on. First, as an initial setting, the dialogue scenario data D9 is read from the HDD 31 and stored in a memory (not shown) in the microcomputer 12 (step S1).

Next, by outputting the menu screen data to the display device 20, the menu screen as shown in FIG. 6 is displayed on the display panel 20b (step S2). In the figure, E1 indicates an anthropomorphic agent. Next, predetermined guidance text data is created based on the dialogue scenario data D9, and the created guidance text data is output to the voice synthesizer 23, so that the guidance text is output by voice from the speaker 25 (step S3). . For example, a guidance sentence such as “Do you want to help with the operation?” Is output from the speaker 25. At this time, it is desirable to move the mouth of the agent E1 so that the agent E1 is guiding.

Then, based on the information obtained from the microphone 21, “Yes” from the user
If it is determined whether or not there is a response corresponding to “Yes” (step S4), and if it is determined that there is a response corresponding to “Yes” from the user, then either the navigation function or the audio function can be selected. A screen is displayed on the display panel 20b (step S5).
Based on the dialogue scenario data D9, predetermined guidance text data is created, and the predetermined guidance text is output by voice from the speaker 25 in the same manner as described above (step S6). For example, a guidance sentence such as “Do you want to operate the navigation function or the audio function?” Is output from the speaker 25.

Thereafter, based on the information obtained from the microphone 21, it is determined whether or not there is a response corresponding to “navigation” from the user (step S7), and if it is determined that there is a response corresponding to “navigation” from the user. The navigation control unit 14 is instructed to perform “navigation processing” (see FIG. 7) such as destination setting (step S8).

Next, it is determined whether or not there has been an instruction from the user to activate the audio function (for example, whether or not a changeover switch for switching between a navigation function and an audio function provided on the remote controller 19 has been pressed) (step S40). S9) If it is determined that there is an instruction from the user to activate the audio function, “audio processing” (see FIG. 10) is performed (step S10). On the other hand, if it is determined that there is no instruction to activate the audio function, the process directly returns to step S9.

On the other hand, if it is determined in step S7 that there is no response corresponding to “navigation” from the user, it is then determined whether or not there is a response corresponding to “audio” from the user (step S11). "Audio processing" (see FIG. 10) is performed (step S10). On the other hand, if it is determined that there is no response corresponding to “audio”, the process returns to step S7.

If it is determined in step S4 that there is no response corresponding to “Yes” from the user, it is then determined whether there is a response corresponding to “No” from the user (step S12). If it is determined that there is a response corresponding to “”, next, predetermined guidance text data is created based on the dialogue scenario data D9, and a predetermined guidance text is output from the speaker 25 by voice (step S13). For example, “So, if you need me (Agent E1)
"Please call me" is output from the speaker 25. After that, based on processing without agent assistance, that is, based only on user actions (manual and voice)
User operation processing "(see FIG. 18) is performed (step S14).

On the other hand, if it is determined in step S12 that there is no response corresponding to “No” from the user, the process returns to step S4. Even if a predetermined time (for example, 6 seconds) elapses, “Ye
If there is no response of “s” or “No”, it may be determined as “Yes” and the process may proceed to step S5. Further, the responses “Yes”, “No”, “navigation”, and “audio” are not limited to voice, and a touch operation on the display panel 20b may be adopted.

Next, a processing operation [1-2] performed by the microcomputer 12 (the navigation control unit 14) in the audio apparatus 11 configured to include the playlist creation apparatus and the music playback apparatus according to the embodiment (1) is illustrated. This will be described based on the flowchart shown in FIG. This processing operation [1-2] is an operation performed when an instruction to perform navigation processing is given from the audio control unit 13 which is the main control unit (step S8 in FIG. 5).

First, by limiting the speech recognition vocabulary to navigation (for example, removing the audio vocabulary), speech recognition is enhanced (step S21). In another embodiment,
The vocabulary for speech recognition is not limited but vocabulary weighting may be performed. For example, weighting is performed so as to reduce the hit probability of the vocabulary for audio.

Next, a menu screen for navigation is displayed on the display panel 20b (step S22), predetermined guidance text data is created based on the dialogue scenario data D9, and a predetermined guidance text is output from the speaker 25 by voice. (Step S23). For example, a guidance sentence such as “Are you sure you want to select a destination?” Is output from the speaker 25.

Then, based on the information obtained from the microphone 21, “Yes” from the user
It is determined whether or not there is a response corresponding to (Yes in step S24).
If it is determined that there is a response corresponding to, next, “destination selection processing” (see FIG. 8) is performed (see FIG. 8).
Step S25).

When the destination G selection process is completed, a guidance process for guiding the vehicle M to the destination G is performed (step S26), and then it is determined whether or not the vehicle M has reached the destination G (step S27).
). If it is determined that the vehicle M has not reached the destination G, a time Ta required for the vehicle M to reach the destination G is calculated (step S28), and then the process returns to step S26. on the other hand,
If it is determined that the vehicle M has reached the destination G, the time Ta is set to 0 (step S29).
Then, the processing operation [1-2] is terminated.

If it is determined in step S24 that there is no response corresponding to “Yes” from the user, it is then determined whether or not there is a response corresponding to “No” from the user (step S30). If it is determined that there is a response corresponding to “”, another navigation process other than the destination selection is performed (step S31).

On the other hand, if it is determined in step S30 that there is no response corresponding to “No” from the user, the process returns to step S24. Even if a predetermined time (for example, 6 seconds) elapses, “Y
If there is no response of “es” or “No”, it is determined as “Yes” and step S25 is performed.
You may make it go to. Further, the responses “Yes” and “No” are not limited to voice, and a touch operation on the display panel 20b may be employed.

Next, the microcomputer 12 (the navigation control unit 14) in the audio device 11 configured to include the playlist creation device and the music playback device according to the embodiment (1) performs “
The destination selection process ”(step S25 in FIG. 7) will be described based on the flowchart shown in FIG. First, “profile information setting / reading process” such as setting profile information used for selecting the destination G and reading the set profile information from the HDD 31 (FIG. 9).
(Refer to step S41), and then the process proceeds to step S42.

Examples of usable profile information include user profile information, profile information of users other than the user such as the user's family / friends, and artists (for example, the user's favorite artist). If profile information other than the user is used to select the destination G, for example, the user's father's favorite place is selected as the destination G, or the user's favorite artist's favorite place is selected as the destination G. Will be able to.

In step S42, a selection condition for selecting the destination G is set based on the profile information read from the HDD 31. For example, if the user's friend likes to go to a theme park or park, “theme park” and “park” are set as selection conditions. Also, if you like to go to “Oxland” more specifically, you may make it a selection condition. In addition, based on the user's past visit history data, “other than theme park” may be set as a selection condition if a theme park has been visited recently.

Next, the destination G is selected based on the facility data read from the DVD-ROM 17, the content data stored in the HDD 31, and the set selection conditions (step S43), and information on the selected location ( For example, the facility name, location, and genre) and who used the profile information are stored in the HDD 31 as visit history information in association with the current time (for example, date, time) (step S44). .

It ’s important to note that you ’re not sure if the user will actually visit the selected location,
In another embodiment, when the location is reached, information regarding the location may be stored in the HDD 31 as visit history information. In yet another embodiment, when the destination G is changed by the user, it is determined that the user does not like the location, and the determination result is stored in the HDD 31 as user history information. good. If this history information is used, it is possible to reduce the possibility of selecting a place that the user does not like as the destination G.

Next, the microcomputer 12 (the navigation control unit 14) in the audio device 11 configured to include the playlist creation device and the music playback device according to the embodiment (1) performs “
Profile information reading / setting process "(step S41 in FIG. 8) will be described based on the flowchart shown in FIG. First, profile information used for selecting the destination G is set based on a predetermined condition (step S51). Available profile information includes:
The profile information of the user himself / herself, and the profile information of the user other than the user himself / herself, such as the user's family / friends and artists. In addition, as a setting method of the profile information used for selection of the destination G, a method of setting at random, a method of setting based on the past profile information setting history (for example, avoiding the profile information used last time), etc. Can be mentioned. Further, the user himself / herself may be made to select which profile information should be used.

Next, it is determined whether or not the profile information to be used is that of the user (step S52). If it is determined that the profile information is that of the user, the profile information of the user is read from the HDD 31 (step S53). On the other hand, if it is determined that the profile information to be used is not that of the user, it is then determined whether or not the profile information to be used is that of the user's family / friend (step S54).

If it is determined that the profile information to be used is that of the user's family / friend, one person is selected from the family / friend based on a predetermined condition (step S55), and the profile information of the selected one is read (step S55). S56). In order to read out the profile information of the user's family / friend, the profile information of the user's family / friend may be stored in the HDD 31 in the same manner as the profile information of the user himself / herself.

On the other hand, if it is determined that the profile information to be used is not that of the user's family / friend, then the user's profile information is read (step S57), and the user's favorite artist is based on the read user's profile information. (Step S
58) The profile information of the set artist is acquired from the outside (for example, a server) using the mobile communication device 26 (step S59). The artist profile information does not have to be imported from the outside when stored in the HDD 31.

If destination G is selected based on profile information other than the user's own profile information rather than the user's own profile information, it will be possible to visit places that are rarely visited, making driving more enjoyable be able to. Here, the profile information of the user's family / friends and the user's favorite artist is listed as profile information other than the user himself / herself used for selecting the destination G. However, the profile information other than the user himself / herself is limited to these. Needless to say, it may be a celebrity other than an artist or a general person who is not a celebrity. For example, using profile information of people who visit the same places that people often visit (celebrities and ordinary people), it is estimated that the person visits other places (the user is likely to like them) May be set as the destination G.

In another embodiment, it may not be a real person, such as a user's family or friend, for example, created based on an imaginary person (for example, a character created by a manufacturer) or statistical data. It may be an average person (for example, an average male in his 20s living in Osaka, a female in his 30s who likes sports). Thereby, for example, the setting condition of the profile information to be used can be set to a person of the same age as the user (that is, a person whose birth year is the same or close).

  Next, “audio processing” performed by the microcomputer 12 (the audio control unit 13) in the audio device 11 configured to include the playlist creation device and the music playback device according to the embodiment (1) (step of FIG. 5). S10) will be described based on the flowchart shown in FIG. First, by limiting the speech recognition vocabulary to audio (for example, removing the navigation vocabulary), speech recognition is enhanced (step S61). In another embodiment, vocabulary weighting may be performed instead of limiting the vocabulary for speech recognition. For example, weighting is performed so as to reduce the hit probability of the navigation vocabulary.

Next, an audio menu screen is displayed on the display panel 20b (step S62), predetermined guidance text data is created based on the dialogue scenario data D9, and a predetermined guidance text is output from the speaker 25 by voice. (Step S63). For example, a guidance sentence such as “Do you want to play music or do you want to play a TV program or a radio program?” Is output from the speaker 25.

Thereafter, based on the information obtained from the microphone 21, it is determined whether or not there is a response corresponding to “music” from the user (step S64), and if it is determined that there is a response corresponding to “music” from the user. Next, “music reproduction processing” (see FIG. 11) is performed (step S65).

On the other hand, if it is determined that there is no response corresponding to “music” from the user, it is then determined whether or not there is a response corresponding to “TV” from the user (step S66).
If it is determined that there is a response corresponding to “TV broadcast reception processing” (see FIG. 17), the next step is performed (step S67).

If it is determined that there is no response corresponding to “TV” from the user, it is then determined whether or not there is a response corresponding to “radio” from the user (step S68). If it is determined that there is, then “radio broadcast reception processing” is performed (step S6).
9). The “radio broadcast reception process” is the same as the “television broadcast reception process” described in FIG.

On the other hand, if it is determined in step S68 that there is no response corresponding to “radio” from the user, the process returns to step S64. Even if a predetermined time (for example, 6 seconds) elapses,
If there is no response of “music”, “television”, or “radio”, it may be determined as “music” and the process may proceed to step S65. Further, the response of “music”, “TV”, and “radio” is not limited to voice, and a touch operation on the display panel 20b may be adopted.

  Next, “music reproduction processing” (FIG. 10) performed by the microcomputer 12 (the audio control unit 13) in the audio apparatus 11 including the reproduction list creation apparatus and the music reproduction apparatus according to the embodiment (1). Step S65) will be described based on the flowchart shown in FIG. First, “profile information setting / reading processing” such as setting profile information used for creating a playlist (selecting a music piece) and reading the set profile information from the HDD 31 is performed (step S71), and then step S72. Proceed to

Note that the “profile information setting / reading process” here is the same as the “profile information setting / reading process” shown in FIG. 9, and the profile information used to select the music is the user's own profile. The profile information is not limited to information, and may be profile information of a person other than the user himself / herself (for example, a real person, an imaginary person, or an average person created based on statistical data).

For example, the user's favorite artist's profile information can be set as the profile information used to select the song, and the user's favorite artist can select the song that the user often listens to. The profile information of the person who listens frequently is set as the profile information used for selecting the music, and the music that the person listens to frequently (that is, the music that the user is likely to like) is selected. May be.

In step S72, based on the profile information read from the HDD 31, selection conditions for creating a playlist (that is, selection conditions for selecting music) are set. For example, if the user's friend likes to listen to music without a sense of speed (slow music) or enka, “speed level 2 or lower” and “enka” are set as selection conditions. In addition, if the user likes to listen to the song “xxx” more specifically, it may be set as a selection condition. Further, if the user listens to the song “□ △ ☆” yesterday based on the user's past listening history, “other than □ △ ☆” may be set as the selection condition.
Next, “playlist creation processing” (see FIG. 12) for creating a playlist is performed based on the set selection conditions (see FIG. 12) (step S73). Processing "(see FIG. 13) is performed (step S74).

  Next, “playlist creation processing” performed by the microcomputer 12 (audio control unit 13) in the audio apparatus 11 including the playlist creation apparatus and the music playback apparatus according to the embodiment (1) (FIG. 11). Step S73) will be described based on the flowchart shown in FIG. First, information (for example, date, day of the week, time, time zone, season, weather, type of road on which the vehicle is traveling) related to the traveling environment condition of the vehicle M is acquired (step S81), and based on the acquired information, The reproduction order condition regarding the reproduction order is set (step S82). For example, if the season is spring or summer, the playback order conditions are set so that the songs are played in an order of increasing excitement, or if the season is autumn and winter, it will become increasingly mature The reproduction order condition is set so that the music is reproduced in a proper order.

Next, based on the selection condition for selecting the music and the playback order condition, the music that is recorded on the HDD 31 should be played first, satisfying the selection condition and the playback order condition. A music piece is selected (step S83). Next, based on the selection condition for selecting a song and the playback order condition, the selection condition and the playback order condition are satisfied from the songs recorded in the HDD 31 and should be played back last. A music piece is selected (step S84).

Next, it is determined whether or not the destination G is set and guidance processing to the destination G is performed (step S85). If it is determined that the guidance process to the destination G has been performed, in order to end the reproduction of the music during driving (that is, to end the reproduction of the music before reaching the destination G), Based on the time Ta required to reach the ground G, the playback time of the first song, and the playback time of the last song, the remaining playable time (= time Ta-1 playback time-last song playback time) Calculate (step S86), and then proceed to step S88.

On the other hand, if it is determined that the guidance process to the destination G has not been performed, the total playback time is set to 60 minutes, and the remaining playback time (= 60 minutes—the playback time of the first song—the playback of the last song) Time) is calculated (step S87), and then the process proceeds to step S88. The total playback time may be set by the user in advance or may be freely set at any time.

In step S88, the second and subsequent songs (excluding the last song) are selected based on the selection condition, the reproduction order condition, and the remaining playable time, and a reproduction list is displayed based on the selection result. By displaying on the panel 20b, the reproduction list is introduced to the user (step S89). Next, predetermined guidance text data is created based on the dialogue scenario data D9, and the predetermined guidance text is output by voice from the speaker 25 (step S90). For example, a guidance sentence such as “Are you sure you want to play list?” Is output from the speaker 25.

Then, based on the information obtained from the microphone 21, “Yes” from the user
It is determined whether or not there is a response corresponding to “Yes” (step S91).
If it is determined that there is a response corresponding to, the information about the selected music (for example, music name, singer name, genre) and who used the profile information are then displayed for the current time (for example, It is stored in the HDD 31 as music listening history information in association with the date (time, date) (step S92).

As for the selected song, the user is not sure whether to actually listen,
In another embodiment, when the music actually starts to be reproduced (or completed), the music information may be stored in the HDD 31 as music listening history information. In still another embodiment, when playback is stopped by the user, it may be determined that the user does not like the music and the determination result is stored in the HDD 31 as user history information. If this history information is used, it is possible to reduce the possibility of selecting music that the user does not like.

On the other hand, if it is determined that there is no response corresponding to “Yes”, then “No” from the user
(Step S93). If it is determined that there is a response corresponding to “No”, an environment in which the playlist can be changed is set (step S94). If it is determined that the change instruction has been completed (step S95), the playlist is changed based on the change instruction (step S96), and then the process returns to step S89.

On the other hand, if it is determined in step S93 that there is no response corresponding to “No” from the user, the process returns to step S91. Even if a predetermined time (for example, 10 seconds) elapses,
If there is no response “Yes” or “No”, it is determined as “Yes”, and step S9 is performed.
You may make it progress to 2. Further, the responses “Yes”, “No”, “navigation”, and “audio” are not limited to voice, and a touch operation on the display panel 20b may be adopted.

  Next, a “list reproduction process” performed by the microcomputer 12 (the audio control unit 13) in the audio apparatus 11 including the reproduction list creation apparatus and the music reproduction apparatus according to the embodiment (1) (FIG. 11). Step S74) will be described based on the flowchart shown in FIG. First, it is determined whether the destination G is set and guidance processing to the destination G is performed (step S101).

If it is determined that the guidance process to the destination G is performed, it is necessary to play the unplayed portion of the music included in the play list based on the play list and the play status of the music. Time Tb is calculated (step S102), and then whether or not the time Ta required to reach the destination G is equal to or longer than the time Tb (that is, the music that was scheduled to be played is played during driving) Whether or not it can be performed) is determined (step S103).

If it is determined that reproduction is possible (Ta ≧ Tb), then the time Ta becomes the time Tc (= time Tb).
It is determined whether or not it is greater than + time α) (step S104). For example, the time α is set to 10 minutes, and it is determined whether or not the reproduction of the music ends much before the arrival at the destination G. If it is determined that the time Ta is larger than the time Tc (that is, the reproduction of the music is finished much before the arrival at the destination G), the reproduction speed is reduced (step S10).
5) Then, it progresses to step S107. On the other hand, if it is determined that the time Ta is not greater than the time Tc, the process directly proceeds to step S107.

Here, the playback speed is reduced to avoid the occurrence of a situation where the playback of the music ends much before the arrival at the destination G. The method of doing is not limited to this, and in another embodiment, for example, the waiting time between each piece of music may be extended, or the end part of each piece of music may be repeated.

If it is determined in step S103 that the time Ta is not equal to or longer than the time Tb (that is, the destination G arrives at the destination G before playing the music in the playlist), the playback speed is increased (step S106). Thereafter, the process proceeds to step S107. It should be noted that here, the playback speed is increased to avoid a situation in which the music that was scheduled to be played is not played during the drive, but the method of avoiding the situation is limited to this. Without
In another embodiment, for example, the waiting time between music pieces may be shortened or cut, or the end part of each music piece may be cut or faded out.

In step S107, the music data is read from the HDD 31, and the music is reproduced according to the reproduction list. Next, it is determined whether or not the reproduction of all the music in the reproduction list is completed (step S108). If it is determined that the reproduction of is completed, the “list reproduction process” is terminated. On the other hand, if it is determined that the process has not been completed, the process returns to step S101.

Next, “list reproduction processing” (step S74 in FIG. 11) in another embodiment will be described based on the flowchart shown in FIG. First, the destination G is set and the destination G
It is determined whether or not the guidance process to the destination G is performed (step S111). If it is determined that the guidance process to the destination G is performed, the playlist, the playback status of the music, and the destination G are reached. Based on the time Ta it takes to drive, while driving (until the vehicle M reaches the destination G),
Whether or not playback is possible is determined for each music piece (step S112).

Based on the determination result, for example, by displaying a screen as shown in FIG. 15 on the display panel 20b, the user is informed of which piece of music can be reproduced (step S113). The first song “XX” to the fourth song “□□□” indicate that playback has ended (black display), and the fifth song “☆☆☆” is playing (blue flashing display). It is shown that the eighth to eighth songs are playable (blue display), and the ninth and tenth songs are not playable (red display). In yet another embodiment, the reproducible status may be indicated in three or more stages, rather than in two stages where reproduction is possible and impossible. For example, as shown in FIG. 16, “□ ☆☆” of the ninth song may be shown to be subtle (yellow display).

Next, an environment in which the order of the playlist can be changed is set (step S114). If it is determined that the user has instructed to change the order of the playlist (step S115), playback of the playlist is performed based on the instruction. The order is changed (step S116), and then the process proceeds to step S117. On the other hand, if it is determined that the instruction to change the order of the playlist has not been given, step S116 is skipped and the process proceeds directly to step S117.

In step S117, the music data is read from the HDD 31, the music is reproduced according to the reproduction list, and then it is determined whether or not the reproduction of all the music in the reproduction list is completed (step S118). If it is determined that the reproduction of is completed, the “list reproduction process” is terminated. On the other hand, if it is determined that the process has not been completed, the process returns to step S111.

Note that, here, a case has been described in which music is played in the order in accordance with the playback order of the playlist (including the playlist after the change), but in another embodiment, according to the playback order of the playlist. Rather than setting the environment in which the user can perform playback instructions in a random order, and if there is a playback instruction in a random order, songs in a random order rather than in the playback order of the playlist You may make it perform reproduction | regeneration. This means that, for example, a good piece of music is played at the beginning, a quiet piece of music is played on the way, and a ballad is played at the end. You will be able to enjoy the performance in the form of no.

  Next, “TV broadcast reception processing” performed by the microcomputer 12 (the audio control unit 13) in the audio apparatus 11 including the playlist creation apparatus and the music playback apparatus according to the embodiment (1) (FIG. 10). Step S67) will be described based on the flowchart shown in FIG. First, profile information used for selecting a television program is set, the set profile information is read from the HDD 31 or the like (step S121), and the process proceeds to step S122. The “profile information setting / reading processing” here is the same as the processing shown in FIG.

In step S122, selection conditions for selecting a television program are set based on the profile information read from the HDD 31. For example, if the user's favorite artist likes to watch a sports program, the selection condition is set to “sport level 4 or higher”. Further, if the user likes to watch a TV program “Sports XX” more specifically, it may be set as a selection condition.

Next, the mobile communication device 26 is used to acquire the information from a server that provides information related to the contents of the television program (step S123), and reception is possible based on the acquired information and the selection condition. A program satisfying the selection condition is selected from the programs (step S124).
) In order to view the selected program, the reception frequency in the broadcast wave receiver 16 is adjusted, the video of the received television program is displayed on the display panel 20b, and the sound is output from the speaker 25 (step S125).

Thereafter, information relating to the contents of the viewed TV program and who used the profile information are stored in the HDD 31 as TV program viewing history information in association with the current time (for example, year, month, day) ( Step S126). Regarding the time, not only the reception start time but also the reception end time may be stored in the HDD 31 as history information.

Further, here, information related to the contents of the program is stored in the HDD 31 as viewing history information. However, in another embodiment, information related to a broadcasting station broadcasting the viewed broadcast program (for example, a broadcasting station) Name, frequency, and genre) as viewing history information.
1 may be stored.

  Next, “user operation processing” (FIG. 5) performed by the microcomputer 12 (the audio control unit 13) in the audio device 11 configured to include the playlist creation device and the music playback device according to the embodiment (1). Step S14) will be described based on the flowchart shown in FIG. First, a screen capable of selecting either the navigation function or the audio function is displayed on the display panel 20b (step S131).

Next, it is determined whether or not an instruction to operate the navigation function by the user has been performed (step S132). If it is determined that an instruction to operate the navigation function has been performed by the user, the navigation controller 14 is instructed. An instruction is given to perform navigation processing (see FIG. 19) such as ground setting (step S133).

Next, it is determined whether or not there has been an instruction from the user to activate the audio function (for example, whether or not a changeover switch for switching between a navigation function and an audio function provided on the remote controller 19 has been pressed) (step S40). If it is determined in step S134 that the user has instructed the audio function to operate, the process proceeds to step S136.

On the other hand, if it is determined in step S132 that an instruction to operate the navigation function has not been issued, it is then determined whether or not an instruction to operate the audio function has been issued by the user (step S135). If it is determined that an instruction to operate is issued, the process proceeds to step S136. On the other hand, if it is determined that the instruction to activate the audio function has not been given, the process returns to step S132.

In step S136, it is determined whether or not the user has performed an operation of reproducing music (for example, whether or not an operation of reproducing music stored on a CD or an operation of reproducing music stored in the HDD 31 has been performed). ). If it is determined that the operation for reproducing the music has been performed, the music desired by the user is reproduced based on the operation (step S137).
Information related to the reproduced music (for example, music name, singer name, genre) is stored in the HDD 31 as music listening history information in association with the current time (for example, date, time) (step S141).

On the other hand, if it is determined that the operation for reproducing the music has not been performed, it is next determined whether or not an operation for receiving a television broadcast or a radio broadcast by the user has been performed (step S138).
If it is determined that the operation has been performed, the television broadcast or radio broadcast desired by the user is received based on the operation, and the video is displayed on the display panel 20b.
Audio is output from the speaker 25 (step S139).

Next, information about the contents of the received program (for example, genre, performer, flow in the program) from the server that provides information about the contents of the TV program or radio program using the mobile communication device 26. (Step S140), the acquired information (that is, information about the contents of the watched TV program or the listened radio program) is associated with the current time (for example, date, time), It is stored in the HDD 31 as program viewing history information (step S141).

Here, information related to the contents of the program is stored in the HDD 31 as viewing history information. However, in another embodiment, information related to a broadcasting station that broadcasts a broadcast program that has been viewed or listened to (for example, The broadcast station name, frequency, and genre) may be stored in the HDD 31 as viewing history information.

  Next, a processing operation [1-3] performed by the microcomputer 12 (the navigation control unit 14) in the audio apparatus 11 configured to include the playlist creation apparatus and the music playback apparatus according to the embodiment (1) is illustrated. This will be described based on the flowchart shown in FIG. This processing operation [1-3] is an operation performed when an instruction to perform navigation processing is given from the audio control unit 13 which is the main control unit (step S133 in FIG. 18).

First, a menu screen for navigation is displayed on the display panel 20b (step S1).
51) Next, it is determined whether or not a destination setting operation has been performed by the user (step S152). If it is determined that the destination setting operation has been performed, the information related to the destination G set by the user (for example, the facility name, location, and genre) is associated with the current time (for example, date, time). And stored in the HDD 31 as visit history information (step S15).
3). In addition, since it is not known whether or not the user actually visits the place set as the destination G, in another embodiment, when the destination is reached, information on the place is sent to the HDD 31 as visit history information. You may make it memorize | store.

Next, a guidance process for guiding the vehicle M to the destination G is performed (step S154), and it is determined whether or not the vehicle M has reached the destination G (step S155). If it is determined that the vehicle M has reached the destination G, the processing operation [1-3] is terminated. On the other hand, if it is determined that the vehicle M has not reached the destination G, the process returns to step S154.
