Description of the invention (1) [Technical Field to which the Invention belongs] The present invention relates to a performance information recording device for recording performance information, and compression of performance information by compressing the amount of performance information Device, performance information decoding device for decoding, and telephone terminal device having these devices. [Knowledge technology] Generally, as a way to save MIDI IDI (Musical Instrument Digital Interface) data, standard MI DI files (hereinafter, referred to as SMF) are widely used. In this SMF, as shown in Figure 1 9 As shown, each piece of performance information is composed of two elements of time and event. △ Time refers to the relative time between adjacent events. Events include various performance information such as the state of the tone on or off, the interval (tone number), or the intensity (speed) of the tone. Here, the performance information is set to include information such as the intensity of the sound, the tempo of the performance of the music, and the tempo, in addition to the interval and the length of the sound displayed by the note. Furthermore, the type of the sound source, reset Controller information, etc. Right, in this SM, each performance information is arranged in time order to form a track. Here, the SMF method is not very good in terms of efficient use of memory capacity or transmission path. It records and transmits most of the music data, such as tunes from mobile phones or communication karaoke, and music databases. In the system, it is required to efficiently compress the data amount of the performance information. At the same time, in the incoming tunes of mobile phones, the reproduction of the incoming tunes is used to inform the phone of incoming calls. The paper size of the incoming tunes is subject to the Chinese National Standard (CNS) Α4 specification ( 210 × 297 mm) — -4-(Read the precautions on the back before reading this page) —Installation · f Thread 594670 A7 B7 V. Description of the invention (2) When the file is stored in the mobile phone itself as an SMF file, it is required Record as many song files as possible in a small part of the memory capacity of the mobile phone body. On the other hand, the LZ (L empe I · zif) method of reversibly (without loss) compression of digital data such as text to use text strings (data format) to compress and overlap parts is now being used. Widely used, the l Z method is said to have the highest compression rate among the reversible compression methods commonly used. The LZ method uses the character string to repeat the compression. It has the same number of data forms in a limited range appearing in the input data, and the same data form has a long length, and the compression rate becomes high. . Therefore, the applicant proposed in Japanese Patent Application Laid-Open No. 9 1 6 1 6 8 that before compression by the LZ method, the length of the same data form should be made long before the number of occurrences is large, and the performance information will be displayed at a short distance. Separate into interval, and intensity, and length, and other information, and arrange them in separate areas. Separate performance information at least into interval information, intensity information, and length information and other information. Generates a 1-time code generation means that arranges each information in an individual independent area, and generates a 2-time code generation of the information in each area of the 1-time code that was generated by the aforementioned 1-time code generation means by LZ method compression The performance information compression device of means. In this device, the primary code generation means calculates the common factor of the relative time between events and the common factor of the length of each note, and the relative time between the events and the length of each note. Dividing by these common divisors and encoding makes up the ideal form of the aforementioned proposal. In addition, the primary code generation method applies the Chinese National Standard (CNS) A4 specification (210X297 mm) at this paper size (please read the precautions on the back before you install-Ben Gong) Order the staff of the Intellectual Property Bureau of the Ministry of Economy Printed by a cooperative-5-594670 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _B7 V. Description of the invention (3) Calculate the number of interval information of each note by using a certain number of intervals The residual error of and the actual interval number 値 is expressed as the ideal form of the present invention. In addition, the primary code generation means is based on the number of intensities of the notes that appeared before, and calculates the residual error number of each note according to a certain function formula. Ideal form. In addition, the primary code generation means is constituted by using the parameters of events of the same type that occurred before it, and calculating the number of parameters 特定 of a specific type of event according to a certain function formula, and the residual error expression of the actual parameters 而. The ideal form of the aforementioned proposal. It is an ideal form of the present invention that the primary code generating means arranges the information in the sound track order in this area. Furthermore, the one-time code generation means that the regions with similar properties of data are arranged close to each other is an ideal form of the proposal. [Problems to be Solved by the Invention] Recently, the tune of the tune has been downloaded by the service side of the i mode to obtain the tune of the tune. The user has gradually acquired the tune of the tune of the tune (hereinafter, referred to as a file). When the membership fee is paid, the built-in memory of the mobile phone is small, and when the total file size of the downloaded file exceeds the capacity of the memory, it becomes necessary to delete the previously purchased file. In addition, the same problem occurs in the case where the user inputs his own performance data, or the use of software such as a dedicated personal computer, in the case of a mobile phone body record file. And 'future' as the file format of incoming tunes, it can be predicted that SMF (standard M IDI file) will be used instead of the conventional one (please read the precautions on the back first, then this page) — installed ...

Description of the invention (4) The size of each file will become larger, which is pointed out as a problem. Therefore, it is easy to think that the file size can be reduced by using the file compression technology described in the aforementioned proposal, but by using the CPU mounted on the mobile phone to perform the compression processing as in the aforementioned proposal, as long as it is not completely thawed, All the files, the performance cannot be started at the beginning, and due to the slow processing speed on the actual terminal side, it takes a considerable amount of time after the phone calls to output the reproduced sound of the incoming tune, which becomes the problem. The present invention is made in view of the above-mentioned conventional problems. Therefore, by preliminarily storing one or a plurality of pre-designated files in a defrosted state in the internal or external memory of a telephone terminal such as a mobile phone, a call can be made to the phone. Instantly regenerate incoming tunes. [Means for solving problems] In order to achieve the above-mentioned objects, the present invention: (1) provides a method that can be decoded by: at least separating the performance information of the music into the information of the interval, the information of the intensity of the sound, and the information of the length of the sound, And other information, generating the first-time code generation means of arranging the foregoing information in individual independent regions; and compressing the second-time information of each region of the first-time code generated by the aforementioned first-time code generation means.

First, the input data 1 uses S M F shown in FIG. 7 and FIG. 19 as an example. The format of the S M F is constituted by △ time, state, number of notes, and speed. Here, in this detailed description, the "pronouncement start event" is referred to as a "note on event", and the "pronouncement stop event" is referred to as a "sound book paper size applicable to the Chinese National Standard (CMS) Α4 standard (210X297 public meal)" " " -14-594670 A7 ______B7 V. Description of the invention (Segmentation of traces. Furthermore, a channel map showing the correspondence between the soundtrack and the channel number as shown in Figure 3 is produced, and the subsequent processing is performed in soundtrack units. Here Although most of the events of SMF include channel information, so by dividing the sound track and making the channel map, the channel information of each event can be omitted, and the amount of data can be reduced. Mapping in the analysis means 12 In the processing shown in step 4, the note table shown in Fig. 5 and the controller table shown in Fig. 6 are produced for each sound track. First, △ time and events are sequentially read by SMF (step S 1), and △ time Calculate the time of the event based on the front end of the sound track (hereinafter, simply referred to as the event time) (step S 2). Then, analyze the event and classify the event as "note on event", "note off" There are three types of "events" and "controller events." In the case of the "note on event", the number of notes (intervals of notes) and speed ( The intensity of the note), in the case of the "note off event", calculate the duration (the length of the note) and register it in the note table (steps S 5-S 6). In the case of the "controller event", register it in the figure The controller table shown in FIG. 6 (step S 7). In this way, a note table and a controller table (step S 8 S 1) are prepared for each performance information. Here, the note table is as shown in FIG. 5. The note event information of the sound track is arranged in chronological order, and the controller table is as shown in FIG. 6, and the information of the controller (other than the note) of the sound track is arranged in chronological order. Also, in the "note open event" In the case of writing the number of notes and speed, the time of the event is written into the prescribed field of the note table, and the paper size of the note table applies the Chinese National Standard (CNS) Α4 specification (210 x 297 mm) ) (Please read the notes on the back first (Fill in this page) 11 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs -16- 594670 A7 ____B7 V. Description of the invention (The "note closing reference" field of d is taken as the initial stage and is set to "0". In addition, the event such as The note is closed, and the note table is scanned by the front end to select a time earlier than the note-off event, and the number of notes is the same, and the note-off reference field is set to a note of "0" to correspond to it. The difference between the time when the note is turned on τ ο η and the time that the note is closed Τ 〇ff (Τ 〇ff — Τ ο η) is regarded as the "duration (the length of the note)" and recorded in the "duration" field of the note table at the same time , Set the "Note Off Reference" field to "1". Here, although the idea of "duration" is not included in SM, but by using this, the note closing event can be omitted, and the data capacity can be reduced. In SMF, one note is represented by a combination of one note-on event and one note-off event as shown in FIG. 7, and the Δ time before the note-off event is equivalent to the duration. The number of notes in the note-off event is necessary to obtain the correspondence with the note-on event. If the duration of the note is used to obtain the correspondence between note-on and note-off, it is not necessary. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Also, the speed of the note-off event is faster than receiving almost all sound sources from the M I D I data, so there is no problem with erasure. Therefore, by omitting the note-off event (3 bytes), depending on the situation, there is an increase in the amount of time data. In short, the effect of the note-off event is large, and each note can be reduced by up to 3 bytes. As a result, it is not uncommon to include 10,000 notes in one piece of music. In this case, it can be reduced by a maximum of 30 Kbytes, and the compression effect is large. This paper scale applies the Chinese National Standard (CNS) A4 specification (210 × 297 mm) '-17- 594670 A7 ______B7_ V. Description of the invention (β events, such as events other than note on and note off, will be the time and content of the event It is registered in the controller table. In this way, the events of N A are registered in the note table. The events of NB are registered in the controller table. Next, the note Δ code generating means 13 and the controller △ code generating means 14 are explained. The reason why these two systems are the same is described below by taking the note △ code generating means 13 as an example. The note △ code generating means 1 3 is shown in FIG. 8 'First of all, For each event in the note table, calculate the difference between the time Ding [i] and the time Ding [i — 1] of the previous event: △ T [i] = (T [i) -T [il)) (step S 1 1) 'Write in a predetermined field of the note table (however, i = 1 to NA, T [〇] = 〇). That is, the relative time between each note event is obtained. Printed here by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the SMF, △ time is expressed as a variable length code that takes one-seventh of a beat as the basic unit. The smaller the number, the smaller the number of bytes required. Can be smaller. For example, if it is 1 2 7 or less, 1 byte is sufficient. If it is 1 2 8 or more and 1 6 3 8 3 or less, 2 bytes are required. △ The finer the basic unit of time is, the higher the expressiveness of music can be said, but with this, the number of bytes required also increases. On the other hand, if the survey is actually used for the delta time of the music, many of them do not use the 1 tick of the basic unit. Therefore, many of the delta T [i] are recorded with a capacity that is more than necessary. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -18- 594670 A7 B7 V. Description of the invention (Therefore, in order to obtain the actual relative time accuracy, all relative times registered in the note table △ τ [i] △ T s (step s 1 2). In this case, if it is difficult to find, take the appropriate common divisor as the largest common divisor, and output △ T [i S 1 3 to S 1 7). However, when ΔT [i] is achieved, 编码 Δding step S 1 5 is divided by ΔT s by ΔT s). Therefore, as shown in FIG. 9, the note Δ code is composed of the divisor Δ T s and 値 Δ T a [i] () of the N A number. Here, when decompressing and compressing with this performance information, read 値 aa [i] and multiply it by △ T s to restore it. Therefore, the amount of data can be reduced without losing S M F. For example, in the case of using a basic order with a time of △, which is 1 / 80th of a beat, and ΔT s = 10, the length of a beat is ΔT = 480 or the maximum convention for the largest common divisor is calculated.

On the other hand, in the middle, it is expressed by dividing by z \ Ts, which means that ΔΤ: = 48 or ΔΤ 2 4 can be used, each using 1 byte. That ’s because the △ time equivalent to 1/2 beat is used frequently, so if you can reduce 1 byte each time, the whole music can be reduced by ~ NA Shrinking code (i) Expressive Wide quilt, the length of the S beat or one of the △ capacity controller △ code generation means 1 4 is the same as the note △ code generation means 1 3 except that the processing object is not the note table and the controller table is stored.

Description of Invention (2) 1 F 〇 (hex), FF (hex) (but n = 〇 ~ F (he X ) And η are channel numbers). The "normal event" is to remove the note-on 8 n (he X) and note-off 9 n (he X) from the above M IDI state, but in the present invention, as described above, it is not necessary to express the channel number, There are 7 types of flags for "normal events". Therefore, the flag F has a higher probability than the M I D I state, and the compression ratio in the case of using the L Z method is higher. The code of the "normal event" is after the flag F, and the data bytes of the M I D I status 1 byte of SM F are arranged. Moreover, in SMF, a certain number of types of events occur continuously in a certain number or more, and there are many parts where the parameter 値 (data byte) of each event changes almost by a certain rule. For example, part of the "Tone Wheel Change" event is used. This event is a subtle change in the pitch of the note to enhance the expressiveness of the music. In terms of its nature, many parameters with different plural events are continuously used. Such events are called "continuous events", and this part is called "continuous event blocks". In the following description, as an example of the "continuous event", although "pitch wheel change" is mentioned, it is not limited to this. Map 15 shows an example of the "continuous event block" of SMF. In this case, because the parameters of each event are different, the length of the same data form of the SMF is (△ time.1 byte + state.1 byte), a total of 2 bytes. In this length, it is almost impossible Get the effect of compression by the LZ method. Therefore, for the area where the "tune wheel change" appears continuously for more than a certain number in the controller table, and the parameters change with almost a certain rule, this paper size applies the Chinese National Standard (CNS) Α4 specification (210 × 297 mm) ( Read and read the notes on the back, then fill out this page), 1T printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, employee consumer cooperatives-24- 594670 A7 ___B7 V. Description of the invention (2) The controller code is generated by applying the following processing . First, in the case where the number of "tune wheel changes" does not satisfy a certain number, it is coded as the aforementioned "normal event". Moreover, as in the formula (4), with the parameters 値 p [i-1], pl [i-2], ..., p [.1-1u] of the U events that occurred before as the function h of variables () And residual error r [1] indicates the parameter p [i] of the event in the continuous event block (however, p [i-1] is a parameter before p [i], and p [i-2] is p [i) the parameter of the two previous events 値). The composition of consecutive event codes is as shown in Figure 16, following the flag F which means that the tune wheel changes the continuity. For the events from the first to the U, it is the parameter itself. In the (U + 1) th and subsequent events, r [i] is arranged in chronological order. p [i] = h (p [i-1], p [i-2], ..., p [iU]) + Y [i] (4) However, with the number of events in consecutive event blocks as NC, i = (U + 1) '(U + 2), ..., although the NC function h () can consider all kinds of people, but by choosing as much as possible the same [r] [i] repeated occurrences, in the second code Efficient compression in production means 4 becomes possible. As an example, the effect in the case of using the function of the formula (5) will be described. This means U 2 1, using the difference from the previous parameter. P [i] = P [i— l] + r [i] (5) The paper size is applicable to Chinese and National Standards (CNS) A4 specifications (210X297 mm) (Please read the precautions on the back before filling this page )-Order printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs-25- 594670 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _ ^ _ B7__ V. Description of the Invention (However, the number of events in consecutive event boxes is NC, i = i = 2, 3,…, NC According to this method, the area shown in Figure 15 is converted into the controller code shown in Figure 17. In this case, the data of the second and subsequent events are all the same. [1] Therefore, the compression rate by the LZ method is increased. Also, because the controller code does not include the △ time, even if the Δ time is different for each event, the compression rate of the LZ method is reduced. Rarely. Depending on the situation, instead of (4), you can use the function e () that uses the time information of the event in the variable (6). However, t [i] is the time of the event for which the parameter is obtained , T [i-1] is the time of the event before it. P [U = e (p [卜 1], p [i- 2], "., P [iU], t [i], t [i-1], "., T [iU]) + Y [i] (6) However, let's set the number of events in consecutive event blocks Is NC, i = (U + 1), (U + 2), ..., NC arranges each of the above codes in the area of 攘 18 in the code allocation means 19 to generate the primary code 3. The head is The management information including the start address or length of each code and the aforementioned channel map. As already explained, compared with SMF, each code has the same number of occurrences of the same data, and the length of the same data form is also longer. However, further efforts are made to make the same data form appear at close range. First, in the same type of code, the probability of the same data column appearing is high, so the same type of code is arranged in the order of sound tracks. Moreover, the phonetic paper scale is applicable to China National Standard (CNS) Α4 specification (210X297 mm) (Please read the precautions on the back before this page)

Description of the invention (2 this symbol △ code and controller △ code and duration code are all time information, compared to the different note character numbers. Or speed code, the probability of the same data row is high, so the distances of these are arranged close. Then, return to the example shown in Figure 19, and specifically review to what extent the length of the same data form is improved. Here Each tune is composed of 50 note-on events and 50 note-off events. All △ time is set to 1 byte. 'All events are assumed to be 3 bytes. The number of notes in each tune As before, they are exactly the same. In SMF, the data amount of each tune is: (1 + 3) χ50χ2 = 400 bytes. If the time and speed of each tune are exactly the same, the length of the same data form It is 400 bytes. However, if the total △ time between the two tunes and the speed at which the notes are turned on are set to be different, in SMF, the maximum length of the same data form is the order of the note off state, the number of notes, and the speed 3 Bytes. To this extent, the compression of the LZ method has almost no effect. On the other hand, in the present invention, encoding is performed by separating △ time, number of notes, and speed, at least among the number of notes, 50 bytes. The same data form appears in the same length. As mentioned above, even if the speed of the SMF is completely different, many of the speed codes appear in the same data form. Therefore, the compression rate by the LZ method is clearly improved. From the above description, it can be clearly understood that the first code 3 will not miss the amount of music information of the SMF and can reduce the amount of data. At the same time, compared with SMF, the length of the same data form is longer and the number of occurrences is greater. Moreover, because of their nature of close range, in the secondary code generation method 4, you can do (please read the precautions on the back-install-then write the book I). Order-line · This paper size applies to China National Standard (CNS) A4 Specification (210 × 297 mm) 594670 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ___B7 V. Invention Description (2 effective compression today. Also, this one-time code itself It also becomes a reasonably compressed amount of data, and the primary code 3 can also be directly output. In the secondary code generating means 4, the output 3 of the primary code generating means 2 is compressed by the LZ method. The LZ method is a widely used method in the compression programs of gz ip and L Η A. This is to search for the same data form from the input data. If it exists, by replacing it with (the distance to the form that appeared in the past, (Form length) to reduce the amount of data. For example, "ABCED" is repeated, and the data of "ABCDEABCE DF" is replaced with "ABCEDE (5, 5) F" information. The compression code (5, 5) means to return 5 characters and copy 5 characters. The treatment should be as follows. The generation of the secondary code 5 is performed by sequentially moving the processing position from the front end of the primary code 3. If the data form of the processing position is consistent with the previous data form within a certain range, the distance from the processing position to the data form and the length of the consistent data form are output as the second code 5 and the processing position is moved to the first position. The end of the two data formats will continue to be processed. If the data format of the processing location is inconsistent with the previous data format within a certain range, copy the code 3 times i as the second code 5 and output. It can be clearly understood from the above description that the larger the two same data areas, the higher the compression rate becomes. In addition, the distance of the same data needs to be within a certain range. As mentioned above, the same tune is used repeatedly in the music, but under the original SMF, if you compare these materials, the same paper size applies the Chinese National Standard (CNS) M specification (210 × 297 mm) " -28-(Please read the precautions on the back before this page).

This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -45- 594670 A7 ___B7_ 5. Description of the invention (岣 Figure 4 3 shows the fifth embodiment when the compression according to the present invention is performed. In the method, the original performance information is compressed as it is. In the case of using the performance information in the incoming tune, etc., the incoming tune must be reproduced immediately after the call is received. In order to understand the frozen compressed file, a high-speed terminal is required. Processing speed. Therefore, as shown in Figure 4, the performance information file is divided into two blocks of box 1 and box 2 on the time series, and compressed in individual box units. At this time, box 1 is as much as possible. On the terminal side, the data can be thawed immediately, and compression is performed only once, but not twice. Block 2 is performed in order to reduce the overall memory capacity or the size of the transmission file. Encoding and compression of secondary encoding. In this way, the compression block 1 to which only the primary encoding is applied and the compression block 2 to which the primary encoding and the secondary encoding are applied are transmitted as one file. Send it and record it in the memory on the terminal side. The employee ’s consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints a block 1 such as the first 5 seconds, etc., to make it short to some extent. Thaw the compressed block 1, while regenerating the incoming tune equivalent to the part of block 1, while thawing the compressed block 2 at the same time. Therefore, if block 1 has sufficient time for thawing of block 2 to be as short as possible It is better. This is also important in terms of shortening the operation time of thawing the compressed block 1. Figure 4 shows the encoding process of the fifth embodiment. First, the SMF is taken (step 601), and in step 602 Divide the SMF by 2 on the time axis, treat the first 5 seconds as block 1, and the remaining part as block 2. Also, in step 6 0 3, encode the block 1 once, and thus, in step 6 0 4. Generate compressed block 1 of compressed block 1.

Description of the invention (called, in step 6 0 5, Primary encoding and secondary encoding 2 'In step 606, the file of compressed box 2 is generated. Furthermore, the files of compressed box 1 and compressed box 2 are aggregated into 1 (step 607), and the encoding is finally printed. Next, the operation during reproduction will be described with reference to FIGS. 4 5 and 4 6. When a call occurs, the music file corresponding to the opponent of the message is retrieved into the information memory means by the music retrieval means 5 3 4. 5 3 5. In the case that the music file has been included in the information memory means 5 3 5, it can be thawed directly. First, start compressing the thawing of box 1. At this time, the compression block 1 is only encoded once, and is decoded by the primary code decoding means 5 3 1 in FIG. 4 to instantly reproduce the performance information. Furthermore, while regenerating the performance information, defrosting of the cube 2 is started. Compression block 2 is decoded twice by the secondary code decoding means 5 3 2 in FIG. 4 5, and then decoded once by the primary code decoding means 5 3 1. The file size of Box 1 is decoded twice, and the performance information of Box 2 becomes the time sequence that can be reproduced. It is better to wait for the time hesitation. In addition, there is a case where the performance information describes the speed (t e m p 〇) in the bass section, and the reproduction speed must be set to the maximum (fastest) speed on the terminal side. The expanded music data is recorded in the information memory means 5 3 5. Furthermore, by the music reproduction means 5 3 6, the performance information developed in the information memory means 5 3 5 is reproduced. Also, in the above-mentioned embodiment, although the music file corresponding to the sending opponent is selected, it is also possible to use the same incoming tune for all of the sending opponent, and switch the music according to the preference of the user of the telephone.

Invention description (岣 Also, although the above is explained in terms of incoming tunes Even if it is karaoke or BGM, the point at which you can start playing immediately at the time of reproduction instruction, which is enough for practical use, can also be applied to these use forms. [Effects of the Invention] As explained above, as According to the present invention, prior to compression by means such as the LZ method, the length of the same data form is long before the number of occurrences is large, and the appearance information is separated into intervals, intensity, and length and others in close proximity. The primary code is generated by arranging each information in a separate area. The primary code is compressed by the LZ method, which can efficiently compress the amount of data of the performance information and specify the phone in advance on the terminal device side. The music that is reproduced at the time of the call, describes the performance information file of the designated music, and is defrosted twice or once compressed. It is newly saved or added to the recording medium. In addition, when an incoming call is made, the incoming tune can be reproduced immediately, and it has the effect of reducing the size of the memory recorded on the recording medium. Furthermore, by providing such a device, the SMF is divided into two or more At least the first block is a device that does not perform the aforementioned first compression and / or the aforementioned second compression, and can provide a terminal that can immediately reproduce from the compressed state. As a primary code, the performance information is separated into The interval area of the note, the intensity area of the note, the length area of the note, and at least four areas of the other areas are coded, so that the original playing information has no performance taste, and it is familiar It can greatly reduce the data capacity. Therefore, a small-capacity recording medium can be used for storing data.
