<P>PROBLEM TO BE SOLVED: To resume a program under reproduction at a point in time when changing the program from the rest of the program. <P>SOLUTION: A plurality of data corresponding to each content is received from a server device successively in a reproduction order prescribed in a content list acquired from the server device connected via a communication network. If the reproduction position of a selected program is stored in a storage means when pseudo streaming reproduction is performed to a series of programs based on received data in parallel with data reception, data corresponding to the content included in the program start to be reproduced from the reproduction position of the stored program so long as the selected program is already stored in the storage means. The storage means stores the reproduction position of the program during reproduction according to the selection of the other program during program reproduction, thus resuming the remaining program after of the content under reproduction at a point in time when a user changes the program. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an electronic music apparatus and a program that receive data distribution from an external server apparatus via a communication network and reproduce a program composed of music, video, and the like. In particular, the present invention relates to an electronic music apparatus and program that can resume a program that was being played back at the time of switching to another program.

Conventionally, a so-called Internet broadcast or the like, which receives a program made up of music, video, or the like that is data-distributed (for example, download distribution, streaming distribution or pseudo-streaming distribution) from an external server device deployed on the Internet, 2. Description of the Related Art There is known an electronic music apparatus that allows a user to enjoy watching and listening to a program as the received program is reproduced as needed. An example of a technique for receiving and reproducing a program from an external server device via such a communication network is, for example, the technique described in Patent Document 1 shown below. In this Patent Document 1, based on a program file in which a plurality of contents are defined in the order of playback, the server apparatus sequentially pseudo-streams (or progressively) a plurality of contents included in a user-desired program with respect to the client apparatus. (Also referred to as download), and a technique is described in which a client device reproduces a plurality of contents delivered from a server device while sequentially receiving the content.
JP 2002-335507 A

  By the way, for example, in order to select a favorite program from among a large number of programs or to enjoy a variety of contents little by little, other users frequently play a program during a relatively short time. There is a case of switching to a program. In the conventional technology described above, when a user switches programs, the program is always started to be played back in order from the content defined at the head of each program in accordance with the switching of the program. This is because, based on the program file corresponding to the switched program, the server device again performs pseudo streaming distribution of a plurality of contents specified in the program file in order from the top. However, when it is desired to frequently switch programs during a relatively short time, it is very inconvenient that playback can always be started only from the beginning of each program. Therefore, when a re-switching operation to a program that has been switched to another program during playback is performed, the program that was being played back is being played back at the time of switching to another program. Electronic music devices that can be resumed are very useful, but none of them have been.

  The present invention has been made in view of the above points, and when a program composed of a plurality of contents that are pseudo-streamed distributed from a server device via a communication network is switched during playback, the program is switched. It is an object of the present invention to provide an electronic music apparatus and a program that can resume a program from the continuation of the content being reproduced.

  An electronic music apparatus according to the present invention is an electronic music apparatus that reproduces a series of programs composed of a plurality of contents in response to data distribution from a server apparatus connected via a communication network, and a selection for selecting a program Stipulated in the acquired content list, the acquisition means for acquiring from the server device a content list that defines the playback order of a plurality of contents included in the selected program based on the selection of the program; Reproduction means for sequentially receiving a plurality of data corresponding to each content from the server device in the reproduction order, and performing a pseudo streaming reproduction of a series of programs based on the received data in parallel with the reception of the data; Storage means for storing the playback position of the program that was being played in response to another program being selected during playback of the Control for controlling the playback means to start playback of data corresponding to the content included in the program from the playback position of the stored program when the playback position of the stored program is stored in the storage means Means.

  According to the present invention, a plurality of data corresponding to each content is sequentially received from the server device in the playback order defined in the content list acquired from the server device connected via the communication network, and the data In parallel with the reception, when pseudo-stream playback of a series of programs based on the received data, if the playback position of the selected program is stored in the storage means, the playback position of the stored program is The reproduction of data corresponding to the content included in the program is started. The storage means stores the playback position of the program being played in response to the selection of another program during the playback of the program. As described above, the reproduction position of the program being reproduced in response to the switching (selection) to another program by the user is stored, and when the program switched during the reproduction is selected again, Since the playback of the program is started from the playback position based on the stored playback position of the program, even when the user frequently switches the program, the program is being played at the time the program is switched. The program can be resumed from the continuation of the content.

  The present invention may be constructed and implemented not only as an apparatus invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

  According to the present invention, in response to switching (selection) of a program, the playback position of the program being played back at the time of switching is stored, and switching to a program switched during playback is performed again Since the reproduction of the program is started from the reproduction position based on the reproduction position of the stored program, the user continues the program being reproduced at the time when the program is switched. It is possible to resume from the beginning, and the effect that it is convenient is obtained.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Further, the CPU 1 is connected to a timer 1A for measuring the interrupt time and various times in the timer interrupt process (interrupt process). For example, the timer 1A generates a clock pulse, and gives the generated clock pulse to the CPU 1 as a processing timing command or to the CPU 1 as an interrupt command. The CPU 1 executes various processes according to these instructions.

  The ROM 2 stores various programs executed by the CPU 1 and various data. The RAM 3 is used as a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined program, or as a memory that stores a currently executed program and related data. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like. In the electronic music apparatus shown in the present embodiment, currently being played back, such as “selected program list”, “current program designation information”, “current content list”, “current content number”, “current playback position information”, or the like Various information related to the program and contents to be reproduced by the user, position information on the program being reproduced at the time when the program switching operation by the user such as “program recording information” is stored in the RAM 3 (details). (See FIG. 3 to be described later).

  The performance operator 4A is, for example, a keyboard provided with a plurality of keys for selecting the pitch of a musical tone, and has a key switch corresponding to each key. The keyboard etc. can be used for manual performance by hand-playing by the user, as well as program selection / distribution to the external server device 11A connected to the electronic music device via the communication network X. It can also be used as a means for instructing to perform, a means for starting / stopping reproduction of a program distributed from the server apparatus 11A, and the like. The performance operation detection circuit 4 generates a detection output by detecting pressing and release of each key of the performance operator 4A.

  The setting operation element (switch or the like) 5A includes, for example, a program selection switch for selecting a program and a program reproduction switch for instructing start / stop of program reproduction. In response to the operation of the program selection switch, the external server device 11A connected to the electronic music apparatus via the communication network X is instructed to select / distribute the program, and in response to the operation of the program playback switch. The electronic music apparatus performs playback control such as starting / stopping playback of a program distributed from the server apparatus 11A in response to the program selection / distribution instruction. Of course, this reproduction control may include not only reproduction start / stop but also controls such as fast forward, rewind, pause, and frame advance. In addition, the setting operator 5A is also a numeric keypad for inputting numeric data, a keyboard for inputting character data used for selecting / setting / controlling pitches, timbres, effects, etc., or a predetermined data displayed on the display 6A. Various operators such as a mouse used for operating the pointing device may be included. The setting operation detection circuit 5 detects the operation state of each switch, and outputs switch information corresponding to the operation state to the CPU 1 via the data and address bus 1D.

  The display circuit 6 is distributed to a display 6A composed of, for example, a liquid crystal display panel (LCD) or a CRT, but is distributed by an external server device 11A connected to the electronic music device via the communication network X, for example. A program list screen that presents possible programs, an information screen that introduces the contents of the selected program, a playback operation panel screen that controls playback of the program, a predetermined display according to the playback of the program (for example, song position) Or a known screen such as a display screen for displaying a score or an image corresponding to the above or a control state of the CPU 1 is displayed. By referring to these various types of information displayed on the display 6A, the user can easily perform operations related to selection / reproduction of programs, for example.

  The tone generator circuit 7 can simultaneously generate musical tone signals on a plurality of channels, and provides performance information generated in response to manual operation of the performance operator 4A by the user, which is given via the data and address bus 1D. Performance information generated according to the stored performance data, or entity data (for example, performance data, audio data, etc.) delivered from the external server device 11A connected to the electronic music device via the communication network X And a musical tone signal is generated based on the performance information and data. The musical sound signal generated from the sound source circuit 7 is given an effect via the effect circuit 8 and the like, and is generated from the sound system 8A including an amplifier and a speaker. Any conventional configuration may be used for the sound source circuit 7, the effect circuit 8, and the sound system 8A. For example, the tone generator circuit 7 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., and may be configured by software processing by the CPU 1 or by dedicated hardware. May be.

  The nonvolatile memory 9 is a storage device capable of storing and holding, for example, constituted by a semiconductor memory, and can store and hold not only when the power is turned on but also when the power is not turned on. A backup battery may be combined with a volatile memory. The external storage device 10 stores various data and various control programs executed by the CPU 1. When no control program is stored in the ROM 2, the control program is stored in the ROM 2 by storing the control program in the external storage device 10 (for example, a hard disk) and reading it into the RAM 3. The CPU 1 can be operated in the same manner as in the case. In this way, control programs can be easily added and upgraded. The external storage device 9 is not limited to a hard disk (HD), but a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), a DVD (Digital Versatile Disk), etc. Any storage device may be used as long as the storage device uses various external storage media. Alternatively, a semiconductor memory such as a flash memory may be used.

  The communication network interface (I / F) 11 is connected to a wired or wireless communication network X such as a LAN, the Internet, or a telephone line, and communicates with an external server device 11A (server computer) via the communication network X. This is an interface for connecting to the electronic musical instrument side a control program or various data from the server device 11A. Such a communication network interface 11 may be both wired and wireless and may include both. The server device 11A stores a large number of various data (see FIG. 2 to be described later in detail), and a large number of various data stored in response to a request from the electronic musical instrument with respect to the electronic musical instrument connected via the communication network X. The corresponding data can be downloaded or pseudo-streamed according to the data type. Needless to say, if the control program and various data are not stored in the ROM 2 or the external storage device 10 (for example, a hard disk), the control program and various data can be downloaded from the server device 11A.

  The MIDI interface (I / F) 12 is used for inputting performance data (MIDI data) in a MIDI format from another externally connected MIDI device 12A or the like to the electronic musical instrument, or from the electronic musical instrument in a MIDI format. Is an interface for outputting to the other MIDI device 12A or the like. The other MIDI device 12A may be any device that generates data in MIDI format in response to a manual performance operation by a user. Any type of operation device such as a keyboard type, a guitar type, a wind instrument type, a percussion instrument type, a gesture type, etc. (Or comprising an operation form).

  The performance operator 4A is not limited to a keyboard instrument, but may be any type of instrument such as a stringed instrument, a wind instrument, or a percussion instrument. In addition, the performance operator 4A, the display 6A, the sound source circuit 7 and the like are not limited to being built in one device body, but each device is configured separately, and each device is connected using a communication means such as a MIDI interface or various networks. Needless to say, it may be configured to do so. Furthermore, the electronic music apparatus according to the present invention is not limited to electronic musical instruments and personal computers, but can be applied to any form of apparatus / equipment such as a karaoke apparatus, a game apparatus, a portable communication terminal such as a mobile phone, and an automatic performance piano. You may apply. When applied to a portable communication terminal, not only when a predetermined function is completed with only the terminal, but also a part of the function is provided on the server side, and the predetermined function is realized as a whole system composed of the terminal and the server. You may make it do.

  As described above, the electronic music apparatus shown in FIG. 1 receives distribution of various data stored in the server apparatus 11A via the communication network X, and reproduces a program based on the distributed data. Here, various data related to program distribution stored in each of the server apparatus 11A and the electronic music apparatus will be described. First, various data that is stored in the server device 11A and can be distributed to the electronic music device by the server device 11A will be described with reference to FIG. FIG. 2 is a conceptual diagram illustrating an example of various data stored in the server device 11A.

  As shown in FIG. 2, the server device 11A stores data such as “program list”, “program content list (program file)”, “data group” in a ROM, RAM, nonvolatile memory, external storage device or the like. These data are distributed to the electronic music apparatus as needed. The “program list” is data for listing all programs that can be distributed by the server apparatus 11A to the user. For example, the “program list” is a unique “program name” (lock, Jazz). When the server apparatus 11A is connected to the electronic music apparatus via the communication network X, the server apparatus 11A automatically downloads and distributes the “program list” to the electronic music apparatus.

  The “program structure content list” is data indicating content information regarding all the contents included in one program, and includes, for example, “data groups” such as performance data (MIDI data), audio data, moving image data, and still image data. Content information relating to the individual entity data included is stored in the program progression order (reproduction order). For example, one program starts with an opening MC (audio data), the first song (MIDI data), MC (audio data), the second song (audio data), the third song (video data), and the ending MC (audio data). In this way, the “program configuration content list” stores content information regarding each entity data corresponding to the progression order (see the program configuration content list of program 1 in the figure). The content information is information that includes “content basic information”, “content URL”, “content number”, and the like, but since it is publicly known, detailed description thereof is omitted here. The server device 11A downloads and distributes a “program configuration content list” in response to a program selection instruction from an electronic music device connected via the communication network X. The “data group” is entity data corresponding to individual contents included in each program. For example, performance data (MIDI data), audio data, moving picture data, still picture data, and the like are used for generating contents. The data itself. The server apparatus 11A starts pseudo streaming distribution in response to a program playback instruction from an electronic music apparatus connected via the communication network X, and sequentially distributes individual entity data from the “data group”.

  Next, various data stored in the electronic music apparatus will be described with reference to FIG. FIG. 3 is a conceptual diagram showing an example of various data stored in the electronic music apparatus. However, although illustration is omitted here, the electronic music apparatus stores data similar to the data (program list, program configuration content list, data group) stored in the server apparatus 11A, such as the ROM 2, the external storage apparatus 10, and the like. The electronic music device can store a program on the electronic music device alone without receiving distribution from the server device 11A connected via the communication network X using the built-in data. It can also be played. These are, for example, preset song data originally built in the electronic music device, song data created by the user, and song data downloaded by the user for free or free of charge.

  As shown in FIG. 3, the electronic music apparatus stores data in the RAM 3 or the nonvolatile memory 9 according to the data type. Here, the “selected program list”, “current program designation information”, “current content list”, “current content number”, “current playback position information”, and “current performance data” are stored in the RAM 3, and the nonvolatile memory 9 Stores "program record information". The “selected program list” is a “program list” distributed from the server apparatus 11A connected via the communication network X, and the electronic music apparatus displays a list of programs being distributed by the server apparatus 11A based on the “program list”. Can do. “Current program designation information” is data indicating a program selected by the user from the list of programs being distributed. The “current content list” is a “program content list” distributed from the server device 11A connected via the communication network X, and is data indicating content contents included in the program selected by the user. “Current content number” is data indicating the content currently being played back, and is, for example, a unique number assigned in advance for each content.

  “Current playback position information” is data indicating the playback position of the content currently being played back. For example, when the content is a song, the position of the song being played is represented by a combination of the number of measures and the number of beats (for example, the second beat of measure 17). The “current performance data” is simulated from the server apparatus 11A in accordance with the substance data of the content distributed from the server apparatus 11A connected via the communication network X, that is, the program selection / playback operation (also referred to as switching operation) by the user. This is entity data corresponding to a plurality of contents included in each stream-distributed program. These “current content number”, “current playback position information”, and “current performance data” are appropriately updated to those related to the content being played back as the program progresses.

  “Program recording information” is data indicating various types of information related to individual programs reproduced from the time when the electronic music apparatus is powered on until the power is turned off. As shown in the figure, various information relating to each program includes “reproduced program”, “content number”, “reproduction position”, and “recording position of entity data corresponding to the reproduction position”. The “reproduced program” is data indicating a program switched to another program during the program reproduction. The “content number” is data indicating the content that was being reproduced when the program was switched to another program among the content included in the program switched to another program during the program. “Reproduction position” is data indicating to what position the content that was being reproduced when the program was switched to another program was reproduced. For example, when the content being reproduced is music content, the position is represented by a combination of the number of measures and the number of beats. “Recording position of entity data corresponding to the reproduction position” indicates the actual position of the content that was being reproduced when the program was switched to another program, and the entity data corresponding to the content is stored. The data is indicated by the recording position on the device, and the recording position of the actual data includes a memory address and / or a URL (Uniform Resource Locator) that is a network address.

  When the reproduced program is internal data of the electronic music apparatus, the recording position corresponding to the reproduction position in the actual data stored in the internal memory or the external storage device is stored. On the other hand, when the reproduced program is data distributed from the server apparatus 11A, the recording position indicating the storage position in the server apparatus 11A of the substantial data distributed to the electronic music apparatus by the server apparatus 11A is set as a URL or the like. Store by network address.

  Next, in the electronic music apparatus, a specific process (program reproduction process) for reproducing the content included in the program in accordance with the distribution of the program from the server apparatus 11A (specifically, pseudo streaming distribution of entity data) will be described. To do. FIG. 4 is a flowchart showing an example of “program reproduction processing”. However, here, for convenience of illustration, the above processing is divided into the first half and the second half in the order of processing. 4A is a flowchart showing an example of the first half process in the “program reproduction process”, and FIG. 4B is a flowchart showing an example of the second half process subsequent to the first process in the “program reproduction process”. This process is a process executed by operating the program playback switch after selecting a program according to the operation of the program selection switch by the user. Hereinafter, “program reproduction processing” will be described with reference to the flowcharts shown in FIGS. 4A and 4B.

  As shown in FIG. 4A, in step S1, a predetermined program is initialized to current program designation information. Thereby, the program selected first is determined. Here, the predetermined program is, for example, a local program that sequentially plays the built-in music. Note that the current program designation information may be stored in the nonvolatile memory so that the last program selected last time may be selected first time next time, but in this case, the process of step S1 is unnecessary. . Step S2 refers to program recording information based on the set current program designation information. In step S3, the content list of the selected program (program after switching) is acquired from any of the internal memory of the electronic music device, the external storage device, or the server device. In step S4, it is determined whether there is a record corresponding to the program set in the current program designation information in the program record information.

  When it is determined that there is no record of the corresponding program in the program record information (no in step S4), the current content number is set to the top content number of the acquired content list (step S5). Also, the current playback position is set to the top position in the content at the top of the content list (step S6). For example, the current content number is set to the top content number “1”, and the current playback position is set to “1 bar 1st beat”. On the other hand, if it is determined that the corresponding program is recorded in the program record information (step S4: yes), the current content number is changed to the content number of the program record information (step S7). Further, the current playback position is changed to the playback position of the program record information (step S8). In step S9, the corresponding entity data is acquired from any of the internal memory, the external storage device, and the server device based on the set or changed current content number. A step S10 changes the read position of the acquired entity data up to the set or changed current reproduction position. That is, playback position cueing processing is performed. At this time, if the entity data from the server device to at least the current playback position has not been distributed and the entity data in the range is not stored in the memory (RAM), the entity data in the range is distributed. Of course, it is necessary to wait for the cueing process until it is finished.

  As shown in FIG. 4B, step S11 starts reproduction of the acquired entity data. In step S12, it is determined whether or not a program switching operation by the user, that is, a selection / playback operation of a program different from the program being played back has been performed. If it is determined that the program switching operation has been performed (yes in step S12), the reproduction of the program currently being reproduced is stopped, and the reproduction state of the program (reproduction program, content number, reproduction position, recording position) is changed. Record in the program record information (step S17). Also, the current program designation information is changed to the program after switching (step S18). After completion of these processes, the process returns to step S3 in FIG. 4A. On the other hand, if it is determined that the program switching operation has not been performed (no in step S12), the program record information is periodically updated in the current state (step S13). As a result, even if the power is turned off halfway, it is possible to memorize how many bars have been reproduced in the program record information. In the case where the reproduction is resumed from the beginning of the interrupted song or from the beginning of the next song after the interrupted song, the process of step S13 is not necessary.

  In step S14, it is determined whether or not reproduction has been performed up to the end of the entity data. If it is determined that reproduction has not been performed up to the end of the actual data (no in step S14), the process returns to step S12. On the other hand, when it is determined that the reproduction has been performed up to the end of the actual data (step S14: yes), “1” is added to the current content number to update one number (step S15). In step S16, it is determined whether or not the updated current content number exceeds the content number defined at the end of the current content list. If it is determined that the updated current content number does not exceed the content number defined at the end of the current content list (no in step S16), the process returns to step S9 in FIG. 4A. That is, in this case, the succeeding next content in the program is reproduced. On the other hand, if it is determined that the updated current content number exceeds the content number defined at the end of the current content list (step S16: yes), the process returns to step S5 in FIG. 4A. That is, in this case, the program is repeatedly reproduced from the top content.

  In the above-described embodiment, when a selection / playback operation (program switching operation) is performed so that a program switched during playback is played back again, from the playback position of the content being played back at the time of switching. Although the case where playback is started, that is, the case where playback of content whose playback has been stopped in the middle is restarted from the stop position has been described as an example, the present invention is not limited thereto. For example, it is easier for the user to restart the program from the next content following the content, rather than from the middle of the content being played at the time of switching. Therefore, a case where the program is restarted from the beginning of the next content subsequent to the content being reproduced at the time when the switching operation is performed will be described with reference to FIG. FIG. 5 is a flowchart showing another example of the “program reproduction process”.

  Steps S21 to S24 shown in FIG. 5 are the same as the processes from Step S1 to Step S4 in FIG. If it is determined in step S24 that the program record information is not recorded (no in step S24), the process jumps to step S28. On the other hand, if it is determined that there is a record in the program record information (yes in step S24), "1" is added to the current content number to update one number (step S25). Then, it is determined whether or not the updated current content number exceeds the content number defined at the end of the current content list (step S26). If it is determined that the updated current content number exceeds the content number defined at the end of the current content list (yes in step S26), the content of the next program following the current program designation information based on the selected program list The list is acquired from any of the internal memory of the electronic music device, the external storage device, or the server device (step S27). That is, the program to be reproduced is automatically set as the subsequent program. A step S28 sets the current content number to the top content number of the acquired content list.

  In step S29, corresponding entity data is acquired from any of the internal memory, the external storage device, and the server device based on the set or changed current content number. In step S30, reproduction of the acquired entity data is started. In step S31, it is determined whether a program switching operation has been performed by the user. If it is determined that the program switching operation has been performed (yes in step S31), the playback of the currently playing program is stopped, and the playback state of the program (playback program, content number, playback position, recording position) is changed. Record in the program record information (step S34). Also, the current program designation information is changed to the program after switching (step S35). After completion of these processes, the process returns to step S23. On the other hand, if it is determined that the program switching operation has not been performed (no in step S31), the program record information is periodically updated in the current state (step S32). As a result, even if the power is turned off halfway, how many bars have been played is stored in the program record information. Note that when the reproduction is resumed from the beginning of the interrupted song or from the beginning of the next song after the interrupted song, the process of step S32 is not necessary. In step S33, it is determined whether or not reproduction has been performed up to the end of the entity data. If it is determined that the reproduction has not been performed up to the end of the entity data (no in step S33), the process returns to step S31. On the other hand, when it is determined that the reproduction has been performed up to the end of the actual data (step S33: yes), the process returns to step S25.

  As described above, the electronic musical instrument according to the present invention receives a plurality of data corresponding to each content from the server device in the playback order defined in the content list acquired from the server device connected via the communication network. In addition to receiving sequentially, in parallel with the reception of the data, when the pseudo-stream playback of a series of programs based on the received data, the playback position of the selected program is stored in the storage means, The reproduction of data corresponding to the content included in the program is started from the stored program reproduction position. That is, the playback position of the program being played back is stored in response to switching (selection) to another program by the user, and when the program switched during this playback is selected again, the stored position is stored. Based on the playback position of the program, playback of the program is started from the playback position. As a result, even if the user frequently switches the program, the program that is being played back at the time the program is switched is the content of the content that is being played back at the time the program is switched. The program can be resumed from the continuation, which is convenient.

  Note that when a program that was being played back at the time of program switching is played back again, the playback of the program may be started not from the middle of the content but from the beginning of the next content that follows. Further, the program is not limited to restarting from the beginning of the next content, but the program may be restarted from the beginning of the content that was being played back, or the program can be restarted from the content arbitrarily determined by the user. It may be.
