DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENET
Referring now to FIGS. 1 to 3, a description will be given of an embodiment of the invention.
FIG. 1 is a diagram illustrating a schematic configuration of a music-data reproducing system using a download program in accordance with the invention. In FIG. 1, the music-data reproducing system using a download program in accordance with the invention is comprised of a portable telephone 110 capable of fetching music data from a data card 101 into which music data has been fetched in advance; a communication network 120 to which the portable telephone 110 is line-connected through a wireless line; and an information provider (application software storage server) 130 which is a server connected to the communication network 120 through a wire line to provide application software, and in which a plurality of pieces of application software (131, 133) are stored.
Music data which is written in the data card 101 is music data which is written in a music data format such as MP3, MPEG, Quick-Time, etc. For instance, music data of the aforementioned music data format is directly purchased (copied) to the data card 101 or the portable telephone 110 from a personal computer through Internet or from an exclusive-use terminal installed in a convenience store or the like, though not shown.
Music data is thus fetched to the portable telephone. Software for reproducing this music data of the music data format is not installed in advance in the main body of the portable telephone, and necessary software is used by being downloaded from the provider (server) to the portable telephone.
In addition, in a case where application software for reproduction has already been downloaded from the server and has been installed in the portable telephone, and by executing the software as it is, it is possible to reproduce music data according to the user's preferred specifications by a headphone 111 attached to the portable telephone 110 or by the display means.
It should be noted that if the application software for reproduction has not been downloaded from the server, the user inquires the information provider (application software storage server) 130 through the communication network 120 as to what application software is available, and a list of pieces of application software is displayed on the display screen of the portable telephone. If the application software desired by the user is available, an instruction is given to download that application software. After the downloading, this application software is executed, thereby making it possible to reproduce the music data by the headphone 111 attached to the portable telephone 110 or by the display means according to the user's preferred specifications.
FIG. 2 is a diagram illustrating the structure of music data, and music data concerning MP3 is shown in FIG. 2. If a further explanation is given to FIG. 2, “MP3” is written as a data format identifier, “data, mp3” is written as data name, “11630” bytes is written as the data size of the music data proper, and data such as “10, 23, 56, 44, 81, 22, 33, 91, 26, . . . ” in decimal numbers (although essentially in binary numbers) is written as the contents of the music data proper.
FIG. 3 shows a flowchart for explaining the operation of the music-data reproducing system using a download program in accordance with the invention, which is shown in FIG. 1. Hereafter, a description will be given with reference to this flowchart.
First, in Step (abbreviated as St. in the flowchart) 301, music data is fetched to the portable telephone. As for the method of fetching music data, music data is fetched by using the data card shown in FIG. 1 or an I/O interface (not shown) attached to the main body through a communication line. It should be noted that, as for the method of fetching data to the data card, various methods are conceivable in addition to the aforementioned personal computer and exclusive-use terminal installed in a convenience store or the like, and the technical concept of the invention is not restricted solely to the illustrated method of fetching data.
Next, in Step 302, search is made for the presence or absence of application software corresponding to the aforementioned music data. Namely, search is first made as to whether there is a history of having already fetched that application software to the main body of the portable telephone. For example, in a case where reproduction application software of the data format of MP3 or the like has already been fetched, the fact that that application software has been installed in the portable telephone can be known by the search.
However, in a case where there is no history of having fetched such reproduction application software, since the application software of the music data format has not been installed in the portable telephone, the user searches through the communication network whether that application software has been registered in the information provider (application software storage server). At this time, by making an inquiry from the portable telephone to the information provider (application software storage server) for a list of application software registered in the server, the search can be made by the portable telephone side. Hence, from that list the user is able to confirm the presence or absence of the desired application software in the application software storage server. At this stage, the selection of the application software is not made.
Then, if it is determined in Step 303 that the corresponding application software in the portable telephone or in the application software storage server cannot be found as a result of the search, even if the music data is fetched, that data cannot be reproduced; therefore, the processing ends. Meanwhile, if it has been possible to find the corresponding application software in Step 303, the operation proceeds to an ensuing Step 304.
In Step 304, desired application software is selected by the user's operation. FIG. 1 illustrates an example in which music reproducing application software 131 and karaoke application software have been registered in the information provider (application software storage server) 130, but it is possible to select either one or both of them. Meanwhile, in a case where application software can be specified unitarily, the user's selecting operation may be omitted.
Next, the operation proceeds to Step 305 in which a determination is made as to whether or not the user's preferred application software has been installed in the portable telephone. If the user's preferred application software has not been installed in the portable telephone as a result of the determination, the operation proceeds to Step 306. In Step 306, the application software is downloaded from the application software storage server. Subsequently, the operation proceeds to Step 306.
On the other hand, if it is determined in Step 305 that the user's preferred application software has been installed in the portable telephone, the operation proceeds to Step 307. In Step 307, the application software is executed in association with the data. Upon completion of the execution, the processing ends.
As described above, in accordance with the music-data reproducing system using a download program, an advantage is obtained in that it is possible to download application software associated with music data from a server to a portable telephone, and the program downloaded in association with the music data can be executed by the portable telephone.
