Problems solved by technology

[0007] However, the compression rate is about half of that of the original SMF, and it is expected to further improve the compression rate
[0008] In addition, incoming music is represented by a service called i-mode. Although it is currently protected in a closed network, when a system for downloading incoming music on an open network is provided in the future, it will be possible to use common data such as SMF. When the data is collected, there is a problem that the data produced by the supplier at a cost is used twice by a third party without authorization

[0019] figure 1 It is a block diagram illustrating the first embodiment of the data uploading method and the data reproducing method of the present invention.

[0020] exist figure 1 Among them, what 101 represented was the original performance information, which is illustrated here with SMF (Standard MIDIFile: Standard MIDI File) as an example, and it is also possible to form the special format for the above-mentioned incoming music. Since the SMF 101 and the lyric file 102 displaying the lyric text corresponding to the SMF 101 constitute one distribution file, it is converted into the performance information file 104 by the converting means 103 .

[0021] The performance information file 104 can be a special file format capable of describing interval information, sound intensity information, sound length information and other information, or can be the above-mentioned incoming music special format, or SMF and other components.

[0022] The lyrics file 102 is a file describ...

[0035] Refer below figure 2 The second embodiment of the data upload method and the data playback method of the present invention will be described.

[0036] exist figure 2In the above-mentioned first embodiment, the SMF 101 and the lyrics file 102 are input to the conversion device 103, and the performance information file 104 is generated. In this second embodiment, the performance information file 104 is compressed by the first compression means 107 . At this time, as a compression method, a method of performing primary encoding and secondary encoding processing as described in the first embodiment, etc. may be considered. The following takes the execution of primary coding and secondary coding as an example for illustration.

[0037] On the other hand, in the reproduction player 106 for reproducing the performance information file 104, decoding means for decoding the performance information file compressed by the above-mentioned compression method is included (this wi...

[0046] image 3 It is a block diagram showing the third embodiment of the data uploading method and the data reproducing method of the present invention.

[0047] exist figure 2 In the shown embodiment, in the playback player 106 in the portable terminal device 111, a code and a secondary code solution device 122, and a lyric color-changing display sequence generator 119 for displaying lyric words from the lyric file 102 are built in, and The sound reproduction device 121 that will replay SMF 101 is provided additionally, but in image 3 In the third embodiment shown, the primary code and secondary code decoding device 122 , the lyrics color-changing display sequence generator 119 and the sound playback device 121 can all be built in the playback player 106 .

[0048] In addition, the first compression device 107 uses an original compression method of an unpublished algorithm, and the first compression device 107 and the primary code and secondary code decoding device 122 a...

Abstract

To reduce the data quantity of a playing information file and to prevent the illicit use of the playing information file as the reproduction of the playing information file with another playback player is no more possible. This method is to separate the playing information to at least the information on intervals, the information on the intensity of tones, the information on the lengths of the tones and other information and arranging respective pieces of the information to respective independent regions and decoding the primary codes to respective pieces of the information described above that is executed by a primary codes decoder. Secondary codes are formed by compressing the playback player capable of reproducing the playing information and the primary codes.

Description

technical field [0001] The present invention relates to a data upload method and a data playback method capable of efficiently transmitting data such as image data and sound data. Background technique [0002] In the past, in communication terminal devices such as mobile phones, not only a monotonous melody, but a part of various music can be used as the performance of incoming music when a call is received. These call melodies can also be pre-stored in communication terminal devices such as mobile phones, but since the user wishes to use popular music as call melodies, the service can be downloaded from a database installed in a server or the like to the communication terminal device. . [0003] The data downloaded in this way is played back by a playback circuit built in a communication terminal device such as a mobile phone or software for playback stored in a ROM or the like. [0004] As the above-mentioned incoming music, compared with the method of replaying waveform...
