The reproduction method information includes, for example, (1) “random”, (2) “normal”, (3) “random once”, (4) “normal once”, (5) “random loop”, (6) “ For example, “normal loop”. (1) indicates that one or more associated music data is randomly played. In addition, (2) indicates that one or more music data associated with the music data is reproduced as usual (for example, in ascending order of music data identifiers). Further, (3) indicates that one or more pieces of music data associated with each other are reproduced at random once. (4) indicates that one or more pieces of music data associated with each other are reproduced only once as usual. Further, (5) indicates that one or more music data associated with each other is repeatedly reproduced at random. (6) indicates that one or more associated music data is repeatedly reproduced as usual.

  In addition, the scene management information may be associated with timing information indicating the timing of reproducing the music data included in the scene management information. The timing information is, for example, (1) “Time = 1000 msec”, (2) “Time = 2.5 sec, se01.wav”, and the like. (1) starts playback of the corresponding music data after 1000 milliseconds from the start of the running scene (after the scene information acquired by the scene information acquisition unit 12 described later meets the playback start condition) Indicates to do. (2) indicates that 2.5 seconds after the start of the traveling scene, the reproduction of the music data identified by “se01.wav” is started from the music data associated therewith.

  Further, the music switching method information, the playback method information, and the timing information may be anything that realizes the switching of the music data and the playback of the music data as described above, and the type, form, content, etc. are not limited. The music switching method information or the like may be a program that realizes the above processing.

  The scene management information may have a category identifier that identifies the category of music data. The category identifier may identify a so-called genre. The category identifier is, for example, “lock”, “just”, “up tempo”, “slow tempo”, or the like. The category identifier may be the same information as the scene identifier.

  Note that the method of associating each piece of information included in the scene management information is not limited. For example, it may be associated as an attribute value in one element of XML (Extensible Markup Language), may be associated as one record, or a so-called primary key as in an RDB (Relational Database) table. It may be associated with the attribute called. In this case, for example, the scene identifier is the primary key, and two or more tables are associated.

  In one scene management information, the playback start condition and the playback end condition are different, but in two or more scene management information, the playback start condition and the playback end condition may be the same. This means that the reproduction of one different piece of music data is started after the end of the reproduction of one piece of music data. The “after the end” is a concept including “at the same time as the end”.

  The scene information acquisition unit 12 acquires scene information. For example, when acquiring position-related information, the scene information acquisition unit 12 normally acquires map information indicating a map and current position information indicating the current position of the moving object, and sets the current position indicated by the current position information. Corresponding road information is acquired from the map information. The map information usually includes map road information indicating roads on the map, map area information indicating areas on the map, and map landform information indicating the topography on the map. The map road information includes, for example, road name information, road type information, road structure information, speed limit information, road position information indicating the position of a road start point, end point, waypoint, and the like. The map area information includes area name information and area position information indicating the position and range of the area. Further, the map terrain information includes terrain type information, terrain position information indicating the position and range of the terrain, and the like.

  The map information may have route information that is a set of two or more road information. The route information is information indicating a route from the departure place to the destination. In addition, the map information is normally held by the scene information acquisition unit 12, but may be stored in a predetermined storage area or an arbitrary storage area.

  For example, the scene information acquisition unit 12 determines whether or not the acquired current position information matches the position information included in the various pieces of information, and if they match, acquires the various pieces of information including the position information. The “determining whether or not they match” includes determining whether or not they are included in the range indicated by the position information. For example, when acquiring road information, the scene information acquisition unit 12 determines whether the acquired current position information matches the road position information included in the map road information. If they match, the scene information acquisition unit 12 acquires the map road information as road information that is scene information. For example, when acquiring area information, the scene information acquisition unit 12 determines whether the acquired current position information is included in a range indicated by the area position information included in the map area information. If included, the scene information acquisition unit 12 acquires the map area information as area information that is scene information. For example, when acquiring terrain information, the scene information acquisition unit 12 determines whether the acquired current position information matches the terrain position information included in the map terrain information, or included in the range indicated by the terrain position information. To determine whether or not If they match or are included, the scene information acquisition unit 12 acquires the map terrain information as terrain information that is scene information.

  In addition, when acquiring position-related information, the scene information acquisition unit 12 usually performs various position-related information from a satellite navigation system (such as a GPS receiver) or a device that receives position information from a mobile communication base station. Get information. In this case, the scene information acquisition unit 12 may have these devices or may be realized by these devices.

  Also, for example, when acquiring state-related information, the scene information acquisition unit 12 normally determines an ignition sensor that detects whether the engine is on or off, a speedometer that measures the speed of the moving body, and the fuel remaining amount of the moving body. Various state-related information is acquired from a device such as a fuel fuel gauge to be measured. In this case, the scene information acquisition unit 12 may have these devices or may be realized by these devices.

  For example, when acquiring time-related information, the scene information acquisition unit 12 normally acquires time information from a clock. The scene information acquisition unit 12 usually has a correspondence table of time conditions indicating time conditions and time subdivisions, and acquires time subdivisions corresponding to time conditions that the acquired time information matches, Get time zone information. In this case, the scene information acquisition unit 12 may have a clock or may be realized by a clock.

  For example, when acquiring weather-related information, the scene information acquisition unit 12 normally acquires weather-related information such as weather information from a device that receives weather information, forecast weather information, precipitation probability information, and the like. For example, when the weather information or the like is stored in a predetermined storage area or an arbitrary storage area, the scene information acquisition unit 12 may acquire the weather information or the like from the storage area. The scene information acquisition unit 12 usually acquires weather-related information such as rainfall information from a rain gauge that measures rainfall, a thermometer that measures temperature, and a hygrometer that measures humidity. In this case, the scene information acquisition unit 12 may have these devices or may be realized by these devices.

  Further, the scene information acquisition unit 12 may acquire the scene information according to the reproduction start condition stored in the scene management information storage unit 11, for example. For example, the scene information acquisition unit 12 determines what the reproduction start condition indicates according to a predetermined order with respect to the reproduction start condition stored in the scene management information storage unit 11. For example, when the reproduction start condition is a position-related condition that is a condition related to the position of the moving object, the scene information acquisition unit 12 acquires position-related information. For example, when the reproduction start condition is a state-related condition that is a condition related to the state of the moving object, the scene information acquisition unit 12 acquires the state-related information. For example, when the reproduction start condition is a time-related condition that is a condition related to time, the scene information acquisition unit 12 acquires time-related information. For example, when the reproduction start condition is a weather-related condition related to the weather, the scene information acquisition unit 12 acquires the weather-related information.

  Note that the scene information acquisition unit 12 normally continues to acquire scene information from immediately after the vehicle-mounted device 1 is turned on until the power is turned off. The acquisition timing is usually regular such as every second, every 10 minutes, or every hour, but may be irregular. For example, the scene information acquisition unit 12 may acquire scene information each time a region such as a prefecture or a municipality changes. In addition, since the method, procedure, etc. which detect that the area changed are well-known, detailed description is abbreviate | omitted.

  Moreover, the acquisition timing of scene information may be predetermined for each type of scene information. For example, information that changes from moment to moment as the vehicle travels and time elapses, such as position information, speed information, and time information, among scene information may be determined to be acquired periodically. In addition, for example, information that differs for each predetermined region (region, etc.), such as region name information, forecast weather information, and precipitation probability information, among scene information, every time the moving object passes the boundary of the region. It may be decided to get to.

  The processing procedure of the scene information acquisition unit 12 is usually realized by software, and the software is recorded on a recording medium such as a ROM. Also, the scene information acquisition unit 12 usually acquires some of the scene information by means described later.

  The route information storage unit 121 stores route information indicating a route to the destination. The route information usually includes one or more route point information indicating points on the route. The route point information usually has point position information indicating the position of the point.

  The traveling state information acquisition unit 122 acquires current traveling state information that is information relating to the current traveling state of the mobile object. The current running state information is usually current position information, current speed information, and the like.

  The driving state information acquisition means 122 is usually realized by hardware (dedicated circuit) such as a satellite navigation system (such as a GPS receiver), a device that receives position information from a mobile communication base station, or a speedometer. However, it may be realized from an MPU or a memory. The processing procedure of the traveling state information acquisition unit 122 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The point position information acquisition unit 123 acquires the point position information from the route information storage unit 121. The said point position information is the point position information which the route point information which shows the point which normally meets the point conditions which are predetermined conditions has. The “point that matches the point condition” is as described above. In addition, although the said spot conditions are normally hold | maintained at the spot position information acquisition means 123, you may store in arbitrary storage areas.

  For example, when the point condition is “the closest tunnel entrance in the traveling direction”, the point position information acquisition unit 123 acquires one or more route point information indicating the tunnel entrance from the route information storage unit 121. Then, the point position information acquisition unit 123 calculates the distance between the position indicated by the current position information acquired by the traveling state information acquisition unit 122 and the position indicated by the point position information included in the one or more pieces of route point information. The description of the distance calculation method is omitted. Then, the location information acquisition unit 123 acquires location information where the calculated distance is minimum.

  In addition, for example, when the point condition is “the nearest tunnel exit in the traveling direction” or “the closest expressway entrance in the traveling direction”, the point position information acquiring unit 123 performs the same procedure as described above. To acquire the location information.

  The point distance information calculating unit 124 calculates the point distance information from the driving state information acquired by the driving state information acquiring unit 122 and the point position information acquired by the point position information acquiring unit 123. As described above, the distance to the point indicated by the point distance information is usually a spatial distance, but may be a temporal distance. For example, when calculating the point distance information indicating the spatial distance, the point distance information calculating unit 124 includes the current position information acquired by the traveling state information acquiring unit 122 and the point position information acquired by the point position information acquiring unit 123. From this, the spatial distance is calculated. Further, for example, when calculating the point distance information indicating the temporal distance, the point distance information calculating unit 124 calculates the point distance information indicating the temporal distance as described above, and the traveling state information acquiring unit 122 acquires the distance information. The time distance is calculated by dividing the distance information by the current speed information. When calculating the spatial distance, the point distance information calculating unit 124 may acquire the distance calculated when the point position information acquiring unit 123 acquires the point position information, for example.

  The end condition acquisition unit 13 acquires a playback end condition corresponding to the scene information acquired by the scene information acquisition unit 12. The end condition acquisition unit 13 normally determines whether the scene information acquired by the scene information acquisition unit 12 matches any of the reproduction start conditions of one or more scene management information stored in the scene management information storage unit 11. And the reproduction end condition corresponding to the matching reproduction start condition is acquired from the scene management information storage unit 11.

  Also, the end condition acquisition unit 13 may acquire the playback end condition when, for example, the scene information acquired by the scene information acquisition unit 12 matches a playback start condition different from the playback start condition that matches the previous one. Good. That is, the end condition acquisition unit 13 does not have to acquire the playback end condition while the scene information matches the same playback start condition.

  For example, it is assumed that the scene information acquisition unit 12 acquires road type information “general national highway”. Then, the end condition acquisition unit 13 acquires a playback end condition corresponding to the playback start condition that matches the “general national highway”. Thereafter, when the scene information acquisition unit 12 acquires the road type information “general national highway” again at the next acquisition timing, the end condition acquisition unit 13 reproduces the reproduction corresponding to the reproduction start condition that matches the “general national highway”. The end condition may not be acquired. Further, after that, it is assumed that the scene information acquisition unit 12 acquires different road type information “high-speed automobile national highway”. Then, the end condition acquisition unit 13 acquires a playback end condition corresponding to the playback start condition that matches the “high speed automobile national highway”.

  The music switching method information acquisition unit 14 acquires music switching method information corresponding to the scene information acquired by the scene information acquisition unit 12. Note that the method and procedure for acquiring the music switching method information are the same as the method and procedure for acquiring the ending condition by the ending condition acquiring unit 13, and thus the description thereof is omitted.

  The music data acquisition unit 15 acquires one or more music data corresponding to the scene information acquired by the scene information acquisition unit 12. Note that the method and procedure for obtaining the music data are the same as the method and procedure for obtaining the reproduction end condition by the end condition obtaining unit 13, and thus the description thereof is omitted.

  The music data acquisition unit 15 may acquire one or more music data stored in the scene management information storage unit 11. The acquisition method does not matter. For example, you may acquire randomly and may acquire in the ascending order of the music data identifier which the said music data has, or descending order.

  The control unit 16 instructs the music data playback unit 17 described later to start playback of music data, end playback of music data, temporarily stop music data, start playback from a specified location of music data, and the like. Instruct.

  For example, when the music data acquisition unit 15 acquires one or more pieces of music data, the control unit 16 instructs the music data playback unit 17 to start playback of any one or more pieces of music data. In this case, the control unit 16 normally determines whether or not the music data acquisition unit 15 has acquired music data. When the music data playback unit 17 plays back to the end of the music data and finishes playback, the control unit 16 is one of the one or more music data, and the music data playback unit 17 plays back the music data. The music data playback unit 17 is instructed to start playback of music data that does not exist.

  For example, when the scene information acquired by the scene information acquisition unit 12 matches the reproduction end condition acquired by the end condition acquisition unit 13, the control unit 16 indicates that the reproduction of the music data is ended. The unit 17 is instructed. In this case, the control unit 16 normally determines whether or not the scene information matches the reproduction end condition. At this time, the music data acquisition unit 15 may acquire one or more new music data. Accordingly, the control unit 16 instructs the music data playback unit 17 to start playback of one or more new music data acquired by the music data acquisition unit 15 at the same time as instructing to end the playback. You may instruct.

  Further, for example, when the music data playback unit 17 is playing back music data, and the music data acquisition unit 15 acquires new music data, the control unit 16 temporarily plays back the music data being played back. The music data playback unit 17 is instructed to stop and to start playback of new music data. And the control part 16 records the location which stopped reproduction | regeneration of the said music data. Hereinafter, the stopped location is referred to as a stopped location. The stop location is usually a so-called offset. The offset is, for example, time or the size (capacity) of music data. In addition, the time is usually the time that has already been reproduced, but may be the remaining reproduction time. The size of the music data may be, for example, the size of the music data that has already been reproduced, or the size of the remaining music data. The recording method is not limited. For example, it may be held by the control unit 16 or may be stored in an arbitrary storage area or a predetermined storage area. When the music data playback unit 17 finishes playing the new music data, the control unit 16 first acquires a stop point. The “when the reproduction of the music data is completed” means that the control unit 16 instructs the music data reproduction unit 17 to end the reproduction of the music data, or the music data reproduction unit 17 reproduces the music data to the end. And when it ends. Then, the control unit 16 instructs the music data playback unit 17 to start playback of the music data whose playback has been temporarily stopped from the stop point.

  When instructing the start of playback or the end of playback, the control unit 16 normally starts the playback or ends the playback according to the music switching method information acquired by the music switching method information acquisition unit 14. The data reproduction unit 17 is instructed. For example, when the music switching method information is “start = fade in”, the control unit 16 instructs the music data playback unit 17 to start playback by fading in. When the music switching method information is “end = fade out”, the control unit 16 instructs the music data playback unit 17 to end playback by fading out. When the music switching method information is “crossfade”, the control unit 16 instructs the music data playback unit 17 to start playback and end playback by crossfading.

  In addition, the control part 16 controls the music data reproduction | regeneration part 17 normally with the combination of said 1 or more instruction | indication. In addition, the “end” and “stop” are generally synonymous.

  The music data playback unit 17 starts playback of one or more music data acquired by the music data acquisition unit 15, ends playback of the music data, temporarily stops the music data, and a location specified by the music data Start playback from. Since the method and procedure for reproducing the music data are known, detailed description thereof is omitted. Further, the reproduction of the music data may be synonymous with the output of the music data. Output is usually output to a speaker.

  The music data playback unit 17 normally performs the start of playback in accordance with an instruction from the control unit 16. For example, when the control unit 16 instructs to start reproduction of music data, the music data reproduction unit 17 starts reproduction of music data. For example, when the control unit 16 instructs to end the reproduction of the music data, the music data reproduction unit 17 ends the reproduction of the music data. The other processes are the same as the contents of the above instruction, and will not be described here.

  Further, for example, when receiving an instruction to end the reproduction of the music data from the control unit 16, the music data reproduction unit 17 places the end of the reproduction in an arbitrary storage area or a predetermined storage area. You may accumulate. The “finished place” has the same meaning as the “stop place”.

  The music data playback unit 17 may or may not include an output device such as a speaker. The music data reproducing unit 17 can be realized by driver software of an output device or driver software of an output device and an output device.

  The scene management information storage unit 11 and the path information storage unit 121 are preferably non-volatile recording media, but can also be realized by volatile recording media.

  In addition, the scene information acquisition unit 12, the point position information acquisition unit 123, the point distance information calculation unit 124, the end condition acquisition unit 13, the music switching method information acquisition unit 14, the music data acquisition unit 15, and the control unit 16 are usually MPUs. Or a memory or the like. The processing procedure of the scene information acquisition unit 12 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  FIG. 4 is a block diagram of the in-vehicle device 2 in the present embodiment. The in-vehicle device 2 includes a scene management information storage unit 21, a music data storage unit 28, a scene information acquisition unit 12, an end condition acquisition unit 23, a music data acquisition unit 25, an attribute change information acquisition unit 29, a control unit 26, and music data reproduction. The unit 27 is provided.

  The scene management information storage unit 21 stores one or more scene management information. The scene management information in the present embodiment is information having one or more attribute change information, a change start condition, and a change end condition in association with each other.

  The attribute change information is information indicating the content of attribute change at the time of reproduction of music data. The “attribute at the time of reproduction” is, for example, volume, left / right balance of volume, tone (tone), pitch (pitch), tempo (beat number, speed), and the like. “Changes” means, for example, increasing the volume, decreasing the volume, increasing the left volume and decreasing the right volume, changing the tone, increasing the pitch, increasing the tempo, etc. It is. That is, the attribute change information includes, for example, (1) “volume + 1”, (2) “left + 2 | right-2”, (3) “high tone: strong | low tone: weak”, and (4) “pitch + 2 semitones”. ”, (5)“ tempo × 90% ”. (1) indicates that the volume is increased by 1. (2) indicates that the left volume is increased by 2 and the right volume is decreased by 2. (3) indicates that the treble is strengthened and the bass is weakened. (4) indicates that the pitch is raised by two semitones. (5) indicates that the tempo is set to 90%. Further, the attribute change information may be a combination of two or more of these.

  Further, the change start condition is the same as the reproduction start condition in the first embodiment, and thus the description thereof is omitted. The change end condition is also the same as the playback end condition in the first embodiment, and thus the description thereof is omitted.

  Further, the scene management information in the present embodiment may have a scene identifier, similar to the scene management information in the first embodiment. In addition, the scene management information in the present embodiment is not limited as long as one or more attribute change information, a reproduction start condition, and a reproduction end condition are associated with each other. Further, in one scene management information in the present embodiment, the playback start condition and the playback end condition are different, but in two or more scene management information, the playback start condition and the playback end condition may be the same.

  The music data storage unit 28 stores one or more music data.

  The end condition acquisition unit 23 acquires a change end condition corresponding to the scene information acquired by the scene information acquisition unit 12. Since the method and procedure for acquiring the change end condition are the same as the method and procedure for acquiring the reproduction end condition by the end condition acquiring unit 13, the description thereof is omitted.

  The music data acquisition unit 25 acquires one or more music data stored in the music data storage unit 28. The acquisition method does not matter. For example, you may acquire randomly and may acquire in the ascending order of the music data identifier which the said music data has, or descending order.

  The attribute change information acquisition unit 29 acquires one or more attribute change information corresponding to the scene information acquired by the scene information acquisition unit 12. Since the method and procedure for acquiring the attribute change information are the same as the method and procedure for acquiring the reproduction end condition by the end condition acquiring unit 23, description thereof will be omitted.

  The control unit 26 usually instructs the music data playback unit 27 described later to restore the attribute at the time of playback of the music data. Further, the control unit 26 may instruct the music data reproducing unit 27 described later to change the attribute at the time of reproducing the music data.

  For example, when the attribute change information acquisition unit 29 acquires the attribute change information, the control unit 26 instructs the music data playback unit 27 to change the playback attribute according to the attribute change information. For example, when the attribute change information indicates that the volume is to be increased, the control unit 26 instructs the music data reproduction unit 27 to increase the volume. For example, when the attribute change information indicates that the pitch is to be lowered, the control unit 26 instructs the music data reproducing unit 27 to lower the pitch.

  For example, when the scene information acquired by the scene information acquisition unit 12 matches the change end condition acquired by the end condition acquisition unit 23, the control unit 26 changes the attribute at the time of playback of the music data being played back before the change. Is returned to the music data reproducing unit 27. In this case, the control unit 26 normally determines whether the scene information matches the change end condition. At this time, the attribute change information acquisition unit 29 may acquire new attribute change information. Therefore, the control unit 26 instructs to return the attribute at the time of reproduction before the change, and at the same time, changes the attribute at the time of reproduction in accordance with the new attribute change information acquired by the attribute change information acquisition unit 29. The playback unit 27 may be instructed.

  Further, when instructing to change or restore the attribute at the time of reproduction, the control unit 26 changes the attribute at the time of reproduction according to any one of two or more attribute change method information indicating the attribute change method at the time of reproduction. The music data reproducing unit 27 may be instructed to restore it. The attribute change method information is normally held by the control unit 26, but may be stored in an attribute change method information storage unit (not shown). The attribute change method information indicates, for example, the time required for the change such as gradually changing the attribute at the time of reproduction or changing the attribute instantaneously. The attribute change method information includes, for example, “gradually”, “slowly”, “instantaneous”, “fast”, “2 seconds”, “5 seconds”, and the like. For example, when the attribute change method information is “gradual”, the control unit 26 instructs the music data playback unit 27 to gradually change the playback attribute. Note that the attribute change method information may or may not be predetermined. If it is determined in advance, it may be determined by user selection, for example.

  The music data reproduction unit 27 reproduces one or more music data acquired by the music data acquisition unit 25. In addition, the music data reproduction unit 27 normally changes the attribute at the time of reproduction of the music data according to the attribute change information acquired by the attribute change information acquisition unit 29. Further, the music data reproducing unit 27 may change the attribute at the time of reproducing the music data in accordance with an instruction from the control unit 26. For example, when the attribute change information or the instruction from the control unit 26 is “volume + 3 | 5 seconds”, the music data reproduction unit 27 increases the volume by 3 for 5 seconds. For example, when the instruction from the control unit 26 is “tempo-4 | instant”, the music data playback unit 27 instantaneously lowers the tempo by four. The other processes are the same as the contents of the above instruction, and will not be described here.

  The music data playback unit 27 may or may not include an output device such as a speaker. The music data reproducing unit 27 can be realized by driver software of an output device or driver software of an output device and an output device.

  The scene management information storage unit 21 and the music data storage unit 28 are preferably non-volatile recording media, but can also be realized by volatile recording media.
