An outline of a content distribution operation of the BGM reproduction system according to the present embodiment will be described with reference to FIGS.
First, the data transmission device 14 describes a reproduction program in the mail text of the electronic mail 24 to the BGM player 16. Further, the data transmitting device 14 stores the name of the content storage server 28 in which the content instructed to be reproduced in the reproduction program is stored, the storage path to the content to be distributed to the BGM player 16, and the content in the BGM player. The path to the folder (content identifier) of the storage means 36 and a processing command indicating the processing for the content are described.
The process for the content includes, for example, a process of downloading the content to the storage unit 36 of the BGM player 16 and a process of decompressing the downloaded content if the content is compressed.
[0021]
The data transmission device 14 simultaneously transmits, to the BGM player 16, an e-mail 24 in which a reproduction program, an identifier of the content stored in the storage unit, and a processing command for the content are described.
The BGM player 16 receives the electronic mail 24 via the input / output means 32.
[0022]
The control unit 30 of the BGM player 16 accesses the content storage server 28 described in the identifier of the received e-mail 24, follows the storage path where the content is stored, and downloads the content from the content storage server 28.
At this time, the identifier analyzing unit 44 analyzes whether or not the identifier specifies the storage unit 36 for storing the content in which storage unit 36. The storage means selection means 45 selects the storage means 36 in which the downloaded content is to be stored, based on the result of the identifier analysis by the identifier analysis means 44 and the configuration of the storage means 36 owned by itself.
[0023]
The BGM playback system 10 according to the present invention aims at distributing the contents in a lump regardless of the hardware configuration of the BGM player 16. May be designated, and in this case, the content is stored in the storage means 36 (c drive in the electronic mail 24 shown in FIG. 2) designated by the identifier.
On the other hand, when the storage means 36 for storing the content is not specified in the identifier (in the electronic mail 24 shown in FIG. 2, it is described as x drive), the storage means selection means 45 has After recognizing the configuration of the storage unit 36, the storage unit 36 in which the content is to be stored is appropriately selected. Note that, when the importance, the frequency of use, the purpose of use, and the like of the content are identifiably described in the identifier, it is also possible to use such information as a material for determining the storage unit 36. When the storage means 36 for storing the content is selected, the content is stored in the storage means 36 (c drive in the present embodiment) of the selected BGM player 16.
[0024]
In order to execute the content stored in the storage means 36 designated by the storage means selection means 45, the reproduction program described in the e-mail is stored in the reproduction program storage means 34, and further described in the reproduction program. It is necessary to change the storage destination path of the stored content to the storage path up to the folder of the storage means 36 of the BGM player 16 selected by the storage means selection means 45.
The rewriting process of the reproduction program is performed by the reproduction program rewriting means 46 based on the analysis result of the identifier by the identifier analysis means 44 and the information of the content storage folder in the storage means 36 selected by the storage means selection means 45. .
[0025]
FIG. 4 is an explanatory diagram showing the rewriting process of the e-mail reproduction program portion shown in FIG. The rewriting process of the reproduction program will be described more specifically with reference to FIG.
In the present embodiment, at the time of transmission from the data transmission device 14, the name of the storage means 36 for storing contents is x drive. The x drive is a non-existent drive name, and the storage means selecting means 45 appropriately selects the storage destination of the content according to the hardware configuration of the BGM player 16.
The content is stored in the selected storage means 36 (c drive in the present embodiment) by the storage means selection means 45.
[0026]
The playback program rewriting means 46 checks the drive name of the storage means 36 selected by the storage means selection means 45, and writes the drive name of the storage destination path of the content described in the playback program from the x drive to the c drive. Replace.
Thereby, in the reproduction program of the BGM player 16 to which the content has been distributed, the storage path of the content temporarily described on the data transmission device 14 side can be matched with the storage path in which the content is actually stored. .
[0027]
The control unit 30 reads from the reproduction program storage means 34 the reproduction program rewritten by the reproduction program rewriting means 46 so as to be suitable for each BGM player 16 and executes the read reproduction program, thereby converting the rewritten reproduction program. Based on this, control is performed so that the contents stored in the storage means 36 are reproduced in order.
[0028]
As described above, by distributing the content using the e-mail system that is widely used at present, low-cost distribution becomes possible. Also, since the e-mail 24 has a content that does not depend on the hardware configuration of the BGM player 16 of the distribution destination, the e-mail 24 can be distributed to a plurality of different BGM players 16 at the same time. Can be done.
[0029]
The contents to be executed based on the playback program are recognized by the hardware configuration in the BGM player 16 and the storage means 36 to be stored is appropriately selected by the storage means selection means 45 in accordance with the hardware configuration. The storage means 36 can be selected according to the free space of the means 36, the purpose of use of the contents, and the like.
Thus, the content can be stored in accordance with the state of the storage means 36 of the BGM player 16 at each store, so that the possibility that the free space of the storage means 36 becomes insufficient is reduced.
[0030]
Further, it is also possible to delete the content in the storage means 36 of the BGM player 16 by a command described in the e-mail 24.
For example, in the case where the free space of the storage unit 36 of the BGM player 16 becomes small, new contents can be stored by removing unnecessary or unused contents among the contents stored in the storage unit 36. Need to be removed. In order to delete the content, an e-mail 24 to which a delete command for deleting the content has been added during the reproduction program may be transmitted to the BGM player 16.
When the BGM player 16 receives the electronic mail 24, the control unit 30 deletes the electronic mail 24 from the storage unit 36 in which the content specified by the delete command is stored. As a result, the free space of the storage unit 36 increases, and new content can be stored.
[0031]
In the above-described embodiment, the BGM player 16 obtains the content by downloading the content from the content storage server 28 based on the content identifier of the e-mail 24 transmitted from the data transmission device 14. Met.
By adopting such a mode, even if the network traffic is not congested and the number of BGM players 16 increases, the congestion of the transmission path from the data transmitting device 14 to the Internet 12 can be reduced.
However, if the data transmission device 14 and the BGM player 16 are connected by a large-capacity line, the contents should be attached to the e-mail from the data transmission device 14 and delivered directly to each BGM player 16. It may be.
In the BGM player 16, the delivered e-mail 24 may be processed by the method described above, and a detailed description thereof will be omitted.
[0032]
As described above, various preferred embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments, and even if many changes are made without changing the gist of the present invention, the present invention is not limited thereto. It goes without saying that it belongs to the technical scope of the invention.
For example, the correction of the actual storage destination of the content reproduced based on the reproduction program does not need to be performed by the reproduction program rewriting means 46, and may be performed by the user on the BGM player 16 side.
[0033]
Further, when the content is accompanied by audio, the configuration may be such that the volume at the time of executing the content can be set in advance. Further, when the content including only audio and the content including only image are combined, Alternatively, the execution time of each content may be synchronized.
[0034]
In the e-mail 24 transmitted when the contents are distributed, a list of contents necessary for the reproduction program is described, the control unit 30 of the BGM player 16 checks the list, and the contents storage device 36 of the BGM player 16 If there is a content stored in the content storage server 28, it is preferable to set the content not to be downloaded from the content storage server 28, because communication costs can be reduced.
[0035]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the present invention, in a uniform BGM playback system basically operated with common content distributed from a distribution side, a content distribution command is created without being conscious of a hardware configuration of a distribution destination. Therefore, the work load on the content distributor can be greatly reduced.
Also, in a BGM player having a plurality of storage means, by storing the minimum necessary content in the same storage means as the storage means in which the reproduction program is stored, a certain storage means is stored for some reason. Even in the case of a failure, there is a remarkable effect that the function as a BGM player is not completely lost.
