(First Example)

(1) Configuration FIG. 1 is a schematic diagram showing the overall configuration of a remote editing system 5 according to a first embodiment of the present invention. The remote editing system 5 is a computer system that realizes an environment in which an editing operator in a remote place edits original musical sound data recorded in a studio or the like, and communicates with each other via a communication network 4 such as the Internet. The editing server 1 and the remote editing terminal 2 are connected to each other. The viewer terminal 3 is connected to the editing server 1 of the remote editing system 5 through the communication network 4 so as to be able to communicate with each other.

  FIG. 2 is a block diagram showing a hardware configuration of the editing server 1. The editing server 1 is a computer that executes AV signal processing, decoding, encoding, and the like by executing an editing program. An HDD (Hard Disk Device) 10 stores an editing program.

Programs and data stored in the HDD 10 are read by the CPU 17 and transferred to the RAM 15. The CPU 17 executes various programs stored in the ROM 16 and the HDD 10 and controls each unit of the editing server 1. The ROM 16 is a nonvolatile memory that stores a startup program. The RAM 15 is a volatile memory that temporarily stores programs, processing target data, and the like. The communication unit 18 controls data transmission / reception processing with the remote editing terminal 2 or the viewer terminal 3 connected via the communication network 4. The external storage interface 12 is connected to an external recording medium such as a removable memory (not shown). Data stored in the external recording medium is input to the editing server 1 by the external storage interface 12, and data in the editing server 1 is output to the external recording medium by the external storage interface 12.

  FIG. 3 is a block diagram showing a hardware configuration of the remote editing terminal 2. The remote editing terminal 2 is a computer that executes AV signal processing, decoding, and the like necessary for remote editing processing by executing a remote editing program. The CPU 33 executes programs stored in the ROM 32 and the HDD 20 to control each unit of the remote editing terminal 2. The ROM 32 is a nonvolatile memory that stores a startup program. The HDD 20 stores a remote editing program. The remote editing program can be stored in the HDD 20 via a communication network 4 from another remote server (not shown). The RAM 31 is a volatile memory that temporarily stores various programs and processing target data. The communication unit 26 controls data transmission / reception processing with the editing server 1 or the like connected via the communication network 4. A display 28 such as an LCD is controlled by a display controller 27 and displays an operation screen for remote editing. The operation unit 30 includes a keyboard, a mouse, and the like. The sound controller 24 includes a D / A converter, an amplifier, and the like, and outputs an audio signal to the speaker 25.

(2) Operation FIG. 4 is a sequence diagram showing a flow of remote editing processing according to the first embodiment.
First, the editing server 1 inputs original musical sound data as original content data recorded in a studio or the like and stores it in the HDD 10 (step S100). Specifically, the CPU 17 inputs original musical sound data stored in a removable memory or hard disk (not shown) from the external storage interface 12 and stores it in the HDD 10. The editing server 1 may input the original musical sound data by recording or may input via the communication network 4. At this time, the external storage interface 12, a microphone (not shown), the communication unit 18, and the like function as “means for inputting original content data”. The original musical sound data is composed of high bit rate PCM data for each track such as vocals and guitars.

  In step S102, the editing server 1 generates a copy of the original musical tone data stored in the HDD 10, irreversibly compresses each track of the copied original musical tone data, and uses the compressed musical tone data at a low bit rate as compressed content data. Generate. Specifically, for example, the CPU 17 converts a copy of the original musical sound data read from the HDD 10 into the RAM 15 into the MP3 format. At this time, the CPU 17 functions as “means for generating compressed content data”. Note that the original musical sound data may be compressed by a dedicated DSP. The lossy compression format may be a WMA format, an AAC format, or the like. Although the bit rate after compression is arbitrary, it is set to, for example, 128 kbps and 64 kbps.

  In step S <b> 104, the editing server 1 transmits the generated compressed musical tone data to the remote editing terminal 2. Specifically, for example, the CPU 17 transmits the compressed musical tone data to the remote editing terminal 2 via the communication unit 18 in response to a transmission request for the compressed musical tone data transmitted from the remote editing terminal 2. At this time, the CPU 17 and the communication unit 18 of the editing server 1 function as “means for transmitting the compressed content data to the remote editing terminal”, and the CPU 33 and the communication unit 26 of the remote editing terminal 2 “receive the compressed content data from the editing server. It functions as a means to do. By transmitting the compressed musical sound data obtained by irreversibly compressing a copy of the original musical sound data from the editing server 1 to the remote editing terminal 2, the amount of data transmitted from the editing server 1 to the remote editing terminal 2 can be reduced.

  The remote editing terminal 2 that has received the compressed musical tone data from the editing server 1 executes the remote editing application and sets editing parameters for the original musical tone data (step S106). Specifically, for example, the CPU 33 decodes the compressed musical tone data to generate musical tone data in the PCM format, and displays an editing operation screen 100 as shown in FIG. The editing operation screen 100 displays an icon for inputting an editing operator's instruction to the remote editing terminal 2, a waveform of musical sound data, and the like. For example, when the editing operator selects a section to be edited from the waveform display area 106 using a mouse or a keyboard, an instruction to set an editing target section is input to the remote editing terminal 2. For example, when the editing operator selects items such as reverb, pitch correction, time stretch, and delay from the effect menu 108, the remote editing terminal 2 displays a detailed setting window for inputting detailed setting instructions for each item. To do. For example, when the editing operator operates icons such as the pan control slider 102 and the volume control slider 104, the remote editing terminal 2 inputs a sound image localization position for each track and a volume setting instruction for each track. The CPU 33 sets the editing parameters of the original musical sound data in accordance with the input setting instruction. At this time, the CPU 33 functions as “means for setting editing parameters”. The edit parameter has an edit item corresponding to the item of the effect menu 108, a start time and an end time of the edit section corresponding to the selected section of the waveform display area 106, and a value indicating the content (for example, sound image localization position) for each edit item. . The editing parameters can be set for each track or for the whole. The editing parameters set for each track are used for editing processing for each track, and the editing parameters set for the whole are used for editing processing after the mixing processing. For example, the edit parameter “pitch (0: 00: 01.00,0: 00: 05.00, + 2);” shown at 112 in FIG. 5B is the track 1 from the first second position to the fifth second from the beginning of the song. This means that the pitch of the interval is corrected by +2 levels. When the editing operator clicks the reproduction icon 110 with the mouse, the CPU 33 performs audio signal processing corresponding to the editing parameters on the low-bit-rate musical sound data, and outputs the data generated as a result to the sound controller 24 to generate the sound. The controller 24 drives the speaker 25 based on the data. Therefore, the editing operator can confirm in advance with low sound quality the musical sound obtained when the editing server 1 edits the original musical sound data based on the editing parameters.

  In step S108, the remote editing terminal 2 transmits the editing parameters set as described above to the editing server 1. Specifically, the editing parameters are transmitted from the communication unit 26 of the remote editing terminal 2 to the communication unit 18 of the editing server 1 via the communication network 4. At this time, the CPU 33 and the communication unit 26 function as “means for transmitting editing parameters to the editing server”. Since the data size of the editing parameter is extremely small compared to the data size of the musical sound data, the amount of data transmitted from the remote editing terminal 2 to the editing server 1 can be reduced by transmitting the editing parameter from the remote editing terminal 2 to the editing server 1. Can be reduced.

  In step S110, the editing server 1 uses the editing parameters received from the remote editing terminal 2 to execute an editing process on the high-bit-rate original musical tone data to generate high-quality edited musical tone data. Specifically, the CPU 17 performs audio signal processing corresponding to the editing parameters on the high-bit-rate original musical tone data read from the HDD 10 and stored in the RAM 15 to generate edited musical tone data in the LR2 channel PCM format, for example. The editing parameters set for each track are used for audio signal processing for each track, and the editing parameters set for the entire track are used for audio signal processing after mixing processing. For example, if time stretch is set for a section of the track specified by the start time and end time, the playback period of that section is specified without changing the pitch (pitch). The CPU 17 executes a process of deforming the waveform of the section so as to change. Further, for example, when pan is set for a certain section of the track, delay processing is executed for the LR channel during mixing processing. At this time, the CPU 17 functions as “means for generating edited content data”. Such editing processing may be executed by a dedicated circuit such as a DSP. By generating edited musical tone data from original musical tone data using the editing parameters received from the remote editing terminal 2, the editing server 1 can output high-quality edited musical tone data.

  In step S112, the editing server 1 transmits the edited musical sound data to the viewer terminal 3 via the communication network 4, transfers it to a speaker via a sound system (not shown), or writes it to a removable memory such as a CD. Equally output. Specifically, for example, the CPU 17 and the communication unit 18 send the edited musical sound data to the communication line in response to the viewing request transmitted from the viewer terminal 3. At this time, the communication unit 18, the external storage interface 12, a sound system (not shown), a speaker, and the like function as “means for outputting edited content data”.

(Second embodiment)
In the second embodiment, an embodiment in which one musical tone data is edited in parallel between the editing server 1 and a plurality of remote editing terminals 2 will be described. FIG. 6 is a sequence diagram showing a flow of remote editing processing according to the second embodiment of the present invention. In the following description, as shown in FIG. 6, an embodiment will be described in which editing parameters for one original musical tone data are set by the remote editing terminals 2A and 2B.
First, the editing server 1 irreversibly compresses a copy of the original musical tone data stored in the HDD 10 or the like to generate compressed musical tone data (step S200). More specifically, for example, a copy of high bit rate original musical tone data having LR2 channels is converted into an MP3 format for generating low bit rate compressed musical tone data.

  In step S202, the editing server 1 transmits the compressed musical tone data to the remote editing terminal 2A. Specifically, for example, the CPU 17 transmits the compressed musical sound data to the remote editing terminal 2A via the communication unit 18 in response to a transmission request from the remote editing terminal 2A.

  In step S204, the editing server 1 transmits the compressed musical sound data to the remote editing terminal 2B as in step S202.

  In step S206, the remote editing terminal 2A executes the remote editing application and sets editing parameters in a specific section of the original musical sound data. Specifically, the CPU 33 executing the remote editing program decodes the compressed musical tone data received from the editing server 1 to generate PCM format musical tone data, and displays the editing operation screen 100 on the display 28. The CPU 33 sets editing parameters in a specific section of the original musical sound data in accordance with setting instructions such as volume and pitch correction input by the editing operator. The specific section means, for example, the first half and second half of a song, a singing voice track and an accompaniment track, and the like.

  In step S210, the remote editing terminal 2B also sets an editing parameter in a specific section of the original musical sound data as in step S206.

  In step S208, the remote editing terminal 2A transmits the set editing parameters to the editing server 1.

  In step S212, the remote editing terminal 2B transmits the set editing parameters to the editing server 1 as in step S208.

  In step S214, the editing server 1 uses the editing parameters of the specific section received from the remote editing terminal 2A and the editing parameters of the specific section received from the remote editing terminal 2B to edit edited musical sound data from the original musical sound data. Generate. Specifically, the CPU 17 reads the original musical tone data from the HDD 10 into the RAM 15, and uses the editing parameters received from the remote editing terminal 2A for the original musical tone data of the section that received the editing parameters from the remote editing terminal 2A. The signal processing is executed, and the original musical tone data of the section that has received the editing parameters from the remote editing terminal 2B is subjected to the audio signal processing using the editing parameters received from the remote editing terminal 2B, and edited in one PCM format. Generated musical tone data.

  As described above, a plurality of remote editing terminals 2 set editing parameters in different sections of the same musical sound data, and the editing server 1 uses the editing parameters received from the plurality of remote editing terminals 2 to produce one original musical sound data. By generating one edited musical tone data from the above, the editing operation of the original musical tone data can be performed in parallel by a plurality of remote editing terminals. Further, the editing server 1 transmits the compressed content data together with the received editing parameters to the remote editing terminal 2, whereby the editing parameters can be reused, and the efficiency of editing work is improved.

In the following description, as shown in FIG. 7, an embodiment in which editing parameters for one original musical tone data are set by two remote editing terminals 2A and 2B will be described.
First, the editing server 1 generates compressed musical tone data from the original musical tone data, and transmits one compressed musical tone data to the remote editing terminals 2A and 2B (steps S300 and 302).

  In step S304, the remote editing terminal 2A sets the editing parameter A over the entire original musical tone data using the received compressed musical tone data, and transmits it to the editing server 1.

  In step S306, as in step S304, the remote editing terminal 2B sets the editing parameter B over the entire original musical tone data using the received compressed musical tone data, and transmits it to the editing server 1.
