[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1. Structure of the Embodiment First, the overall structure of the content transmission and the like of the data structure of the media slot according to the embodiment of the present invention will be described with reference to FIG. 1. In FIG. 1, the mobile phones (external devices) 2, 4, 6 can communicate with each other via the communication network 8 and receive files. Here, it is assumed that the mobile phones 2, 4 are models that can reproduce the private media files described later, but the mobile phone $ is a model that does not correspond to a certain peptide slot case. It is the server 10 of the case sending device, and when the files are transmitted and received between these banks, the files are temporarily stored, and the file format conversion and other processing are performed as necessary. ^ σσ 1 〇 The internal transmission and reception unit 12 performs various files and communication with the communication network g. The CPU (Central Processing Unit) M controls other components based on the second and second sections described below. In ROM (Read Only Memory) 18, a has recalled the initial program loader and so on. A ram (random access memory) 16 is used as a working memory of the CPU 14. On the hard disk, the memory device has recalled the terminal information database 24, which stores information about each mobile phone including the aforementioned lines 2, 4, and 6; the conversion engine%, which is root = necessary conversion to send to each mobile phone Files in the form of programs' and various other programs and data. Here, the identification of each mobile phone corresponding to and transferred to the mobile phone 2, 4 and transferred is given to the terminal information database 4 '.

O: \ 87 \ 87933.DOC 200422882 number 'and the file format that these mobile phones can correspond to 2. The data structure of the implementation, "Back, describes the data format of the daddy file used in this implementation. This data format It is based on the proposal proposed by this applicant, especially the SMAF (registered trademark) method. In this embodiment, the so-called "multimedia rhyme content" refers to plural types including image data, sound data, and text data. For content owners, X e X ^ + test whether to save the content that constitutes multimedia content in a file. The other "private multimedia files" as described in "a" refers to those who store multimedia content in one file. First, the overall structure of a multimedia broadcast is shown in FIG. 3A. In FIG. 3a, in the information block 210, the form of the content (calling melody, karaoke series, advertisement (CM) series), the language of the text information, the text encoding system, and the like are memorized. In the selection data block 220, a text string (text data object) displayed on a display or the like is memorized, and information of a specific representative image or the like (representative content designation information, described later in detail) is memorized. In addition, there are one or a plurality of dent track blocks 230,..., 23, that is, at least one each stores performance information of a music piece. There are one or a plurality of PCM (Pulse Code Modulation) audio magnetic blocks 24, ..., 240. A PCM audio magnetic block 240 includes a plurality of waveform data (sound data objects) and sequence information specifying a timing for reproducing such waveform data. In addition, one or a plurality of graphic magnet blocks 250, ....., 250 store a drawing sequence for a display device. Here, the so-called "drawing sequence" includes, for example, "drawing a specified image data object (bit-mapped image) to a specified position on a drawing surface", "erasing a specified image data object from a drawing surface", etc.—including Instructions. Therefore, by changing the drawing position and repeating the O: \ 87 \ 87933 DOC -12- 200422882 "drawing" and "erasing" of the object, animated images can also be represented. The main magnetic block 260 stores information such as the overall tonality, tempo, and tempo of the music or events (such as pauses or jumps) that control the reproduction system itself of the multimedia file. With each of these blocks 210 to 260, an archive block 200 is formed. "File block" means "multimedia file itself". Next, the data structure of the aforementioned blocks 200 to 260 will be described with reference to FIG. 3B. It is assumed in Fig. 3B 'that the block 300 is any one of the aforementioned blocks 200-260. In the front part of the block 300, a fixed-length (8-byte) block header 3 110 is set. In the block header 3 1 0, the unique block ID and the data size of the block are recorded. Also, the data body about the block 300 is stored in the body part 320. The operation result is memorized in the CRC (Cyclic Redundancy Check) section 33, which applies a specific CRC generator polynomial to the data rows in the block header 310 and the body section 320 to the operator. The CRC section 330 is provided only for the archive block 200, and is provided to check whether the archive block 200 is damaged. 3 · Operation of Embodiment 3 · 1 · Uploading Process Next, the operation of this embodiment will be described. Here, as an example, the operation when the mobile phone 2 and the multimedia file 30 (see FIG. 1) are uploaded by using the mobile phone 4 and 6 as the sending place will be described. In this case, the mobile phone 2 sends an upload request to the feeder 10 via the communication network 8 '. After receiving the upload request, the upload request receiving routine shown in FIG. 2A is displayed on the feeder. After the processing of FIG. M enters the normal SP2 (memory process), the multimedia file is sent by the mobile phone 2 through the communication network 8 and received at the server 10, and the file is stored in the hard disk 22. Secondly, after entering the regular state,

O: \ 87 \ 87933.DOC -13- 200422882: The mobile device of the end device 4,6 ’notifies the main point of uploading the slot case. Hereby, the processing of the upload request ends. 3 · 2 · Download processing = After the media case, the user of the mobile phone 4,6 requested the download of the server case. At this point, after any one of the mobile phones 4, 6 receives the download request, it starts to display on the server 1 () and displays the normal mode. In _, the process enters the routine SP22 (request reception process) = Get the terminal information of the mobile phone for downloading the request source via the communication network ^ of the process into the routine SP24 (determination process), refer to the terminal poor information : Shell database ... Determine whether the mobile phone about the obtained terminal information can reproduce the uploaded multimedia files. "For example, if the terminal requesting the download is a mobile phone 4, it is judged as" YES "here, and the process proceeds to the f-type (transmission process). At this time, the multimedia planting case is still sent to the source of the download request. The terminal of the phone's lamp download request is a terminal that does not correspond to the multimedia slot case, such as mobile phone 6. Proceed to SP26 (conversion process). The conversion engine% is started at the routine sp26 ', and the multimedia slot is converted into one or a plurality of representative content files 32 (see FIG. 1). ... here "the so-called" representative content "means a still image of a moving scene contained in a multimedia file" The text data placed on the moving image ^ The audio data generated in synchronization with the 4 moving sad image is equal to the requirements Source terminal ^ Inner valley and can generate content based on multimedia content. The method of generating the case on behalf of Gubo will be described later. Secondly, processing goes to regular milk $

O: \ 87 \ 87933.DOC -14- 200422882 After that, the generated representative content is sent to the mobile phone of the request source, and the process of downloading the request receiving routine ends. 3.3 Reproduction Process of Multimedia File Now, the operation of reproducing the multimedia file will be described with reference to FIG. 4 on the mobile phone 4 and the like. In FIG. 4, the horizontal axis is the elapsed time after the content reproduction is started, and the length in the horizontal axis direction of the rectangle in the figure * shows the period during which each object is reproduced. : For example, at time ti, the reproduction of the sound data object 11 is started, and the reproduction of the sound data is continued until time t10. At time 12, the reproduction of the image data object (still image) 102 is started, and at time 0, the reproduction of the text data object 108 is started. Therefore, after displaying such multimedia content on a display such as a mobile phone 4, and at time t101, shortly after time t3, an image obtained by adding a text data object 108 to an image data object 102 is displayed. . After time t101, the reproduction of the image data object 10 is started at time 14. At time t5, the reproduction of the image data object 10 is completed. At time t6, the reproduction of the image data object 104 is started. Therefore, at time 1102 shortly after time "1, an image obtained by adding text data objects ι 08 to image data objects 104 and 106 is displayed on a display or the like. For the objects constituting multimedia content, the aforementioned In addition, it is also preferable to include performance information objects (such as the MIDI (SMF) method) recorded in the dent magnetic block 230. 3.4. Data conversion processing (3-26) Secondly, the foregoing of FIG. 2B will be described with reference to FIGS. 3A and 3B. Details of the data conversion processing of the routine SP26. First, the aforementioned selection data block 220 contains information for specifying one or plural representative contents (representative content designation information).

O: \ 87 \ 87933.DOC -15-200422882). The representative content designation information is roughly classified into two types. The first type of information is the information that specifies any object itself as the representative content. For example, in the example of FIG. 4, "image data object 102", "text data object 108", and "sound data object 11" may be designated as representative contents, respectively. In addition, the second type of information is information that designates "display content of the display at a certain time" as the representative content. For example, in the example of FIG. 4, "display state of time", "display state of time t102", etc. may be specified as representative contents. However, the content designated as the representative content is actually different because the correspondence status of the mobile phone 6 according to the download request source is different. 3 · 4 · 1 · When all the representative contents are corresponded In the case where the mobile phone 6 corresponds to all the representative contents, in the aforementioned routine SP26, all the representative contents designation information included in the selection data block 22 is read out. Moreover, for the first type of information, the information about the information = object is generated as the representative content. That is, by representing the image content object fU, the image data object 'then generates a bitmap file, specifying the text file object' generates a text file, and specifying the sound data object, generates a waveform data file as the representative content file. 32. In the case where the designated information of the representative content is the second type of information, all the image data objects to be displayed are extracted on the day of the fingertips, and a single-bit mapping file is produced by synthesizing these. In the example shown in FIG. 4, for example, if "time" is designated as the second type of poor information, the image data object 104, the Zezzi 、,, and the like should be displayed at the time point for retrieval. Bit mapping file for file 32. When 吝 4 — ^, the mapping file is generated, and then at that time

O: \ 87 \ 87933.DOC -16- 2882 Carved 11 02 The text displayed on the screen can be used with caution. 2. The content of the subject object 108 is added to the bitmap file 3 · 4 · 2. If the corresponding representative content is limited, the second mobile phone 6, if the corresponding representative content is limited, Ann 3: With regard to the representative content that can be corresponded, the representative content file A is generated: the mobile phone 6 only corresponds to the text data, and only the text is generated: X subscription mobile phone 6 sometimes even if it is a party that can reproduce the image data file, it is also f Acceptable-Zhang. In this case, as for the image data, only ^ image * data file is used to designate information based on the first representative content of the specified image data object (or time). In addition, the mobile phone 6 sometimes supports only one blade of the case even if it can reproduce image data. For example, the original image data object representing the content is in the JPEG format. When the mobile phone 6 only supports the touch format, it is necessary to convert the image data slot from the IPEG format to the pNG format. In addition, as a case where the recorded performance information is designated in the MIDI format as the representative content, the mobile phone 6 may only respond to the PC-II data or the data designated in the form of a bribe. In this case, based on the original performance information, the form of the music signal of the synthesized PCMf material is converted into a mode. As described above, according to the above-mentioned method, the representative content corresponding to the mobile phone of the download request source is automatically generated. In addition, with this method, because the selection data block in the multimedia file contains one or a plurality of representative content specifying information, the multimedia content and the representative content can be integrated, and the representative image and other can be managed very easily. On behalf of Uchiya. The user of mobile phone 4 corresponding to the reproduction of multimedia files is based on

O: \ 87 \ 87933 DOC -17- 200422882 If necessary, by rewriting the contents of the selection block 220, the contents representing the contents can be arbitrarily edited. The aforementioned first and second types of representative content specifying information may also be mixed together, and needless to say, stored in the selection data block 220. 4. Modifications The present invention is not limited to the aforementioned embodiments, and may be modified in various ways, for example, as follows. (1) In each of the embodiments described above, processing of content data conversion and the like is performed by a program operating on the server 10. However, the application program may be stored only in a recording medium such as a CD-ROM or a floppy disk. And distribution, or distribution via transmission channels. The data format of the multimedia files in the foregoing embodiments is not only used to move files between telephones and other machines, but can also be used, for example, in multimedia file retrieval systems. In other words, by referring to most of the multimedia cases first, the representative content designation information such as still images can be processed on a personal computer to create a list of representative content. In this way, users can grasp the outlines of most multimedia files at a glance, and can quickly retrieve the necessary multimedia files. In the foregoing embodiment, the representative content information ^ information is stored in the multi-body coffin case ^ The multimedia content and the representative content designation information do not necessarily need to be stored in the same-tan case, and both can be stored in other bidding cases. Moreover, the multimedia content itself does not need to be stored in the same slot (multimedia file), and the multimedia content can also be constituted by individual files of each object. The mobile phone on the side of the valley is also applicable to each (4) in the foregoing embodiment. By receiving the operation of the delegate, download multimedia content or

O: \ 87 \ 87933.DOC -18- 200422882 Different representative content sending methods are also good. For example, only the text data object may be sent to the receiving side as an email, and the image data object may be displayed on the day side of the receiving side. The object of the present invention can also be achieved by: supplying a code for recording software that implements the functions of the embodiment to a system or a device, the system or a computer (or a CPU and an MPU) of the device being read out and stored in a storage medium Code. At this time, the code itself read from the storage medium will realize the function of the foregoing embodiment, and the storage medium storing the code will constitute the present invention. When the code is supplied via a transmission medium or the like, the code itself constitutes the present invention. As a memory medium in these cases, downloads and the like can be used in addition to the ROM, which is via a floppy disk (registered trademark), hard disk, optical disk, magneto-optical disk, CD-ROM, CD-R / RW, DVD-ROM , DVD-RAM, DVD-R / RW, DVD + RW, NV-RAM, magnetic tape, non-volatile memory card, or internet. Moreover, by implementing the code read by the computer, not only the functions of the aforementioned embodiment are realized, but also based on the instructions of the code, the OS or the like operating on the computer performs part or all of the actual processing, and the processing It is needless to say that the case of realizing the functions of the aforementioned embodiment is included in the present invention. Furthermore, after the code read from the memory medium is written into the memory, the memory system is inserted into the computer's function expansion board and the function expansion unit connected to the computer. Based on the instructions of the code, the function expansion board and A part or all of the actual processing of the CPU and the like included in the function expansion unit, and the case where the functions of the foregoing embodiment are realized by this processing are also included in this O: \ 87 \ 87933.DOC -19- 200422882 .
