This operation may be performed by directly inputting an address, or by selecting an address registered in advance.
[0046]
The player-specific password description means 75 is activated when the address setting by the address setting means 73 is completed, and selects and sets a player-specific password corresponding to the BGM player 16 as a destination of the e-mail 24 by an operation of the operator. . When the player-specific password is selected by the operation of the operator, the player-specific password description means 75 describes the selected player-specific password 99 in the e-mail 24 of FIG. 7, as shown in FIG.
The player-specific password 99 is a character string determined so as to be different for each BGM player 16. Note that it is not always necessary to assign a different password for each player to each BGM player 16. For example, the BGM players 16 installed in each chain store where a common playback program is used are common. May be assigned a player-specific password.
[0047]
In addition to the player-specific password 99, which is determined differently for each BGM player 16 (or for each chain store), a common player-specific password may be set for all BGM players 16 of the BGM playback system 10. This will be described later.
[0048]
The mail transmitting means 78 can transmit the electronic mail 24 to a specific address of the BGM player 16 set by the address setting means 73 by a predetermined operation by the operator.
When the transmission operation by the mail transmission unit 78 is performed by the operator, the system password description unit 79 is automatically activated. The system password description means 79 describes a predetermined system password 98 in the transmitted e-mail 24 as shown in FIG. The system password 98 is a character string uniquely defined for each BGM playback system 10, and the e-mail 24 in which it is described is used for controlling the BGM player 16 of the specific BGM playback system 10. It is shown that.
When the system password description means 79 describes the system password 98, the e-mail 24 is transmitted to the BGM player 16 corresponding to the address set as the destination via the mail server.
[0049]
In the present embodiment, the command and the reproduction program are described in the text of the electronic mail 24, but a file in which these are described may be attached to the electronic mail 24 as an attached file.
Describing the system password 98 and the player-specific password 99 in the e-mail 24 includes the case where the system password 98 and the player-specific password 99 are described in an attached file attached to the e-mail 24.
[0050]
Next, the internal configuration of the BGM player 16 will be described with reference to FIG.
The BGM player 16 includes a control unit 82 operated by firmware or the like set in advance to control the operation of the entire player, a communication unit 84 for connecting to a communication line such as the Internet 12, and a content according to a schedule such as a calendar. The playback order is determined. The playback program storage unit 86 stores a playback program 80 that controls the control unit 82 so that the content is played back with the determined content. A plurality of contents are stored as digital data. A content storage unit 88 and a reproduction unit 89 including a D / A conversion circuit and an amplification circuit for performing D / A conversion of the content as digital data extracted from the content storage unit 88 are provided.
Further, a speaker 90 for reproducing the content as audio and a monitor device 91 for reproducing the content as video are connected to the reproducing means 89. The speaker 90 and the monitor device 91 may be provided integrally with the BGM player 16 or may be provided separately.
[0051]
The control unit 82 includes a mail receiving unit 83 configured as firmware, a system password checking unit 85, a player-specific password checking unit 87, and a content reproduction control unit 92.
[0052]
The operation of the BGM player 16 will be described.
The mail receiving means 83 of the BGM player 16 receives the e-mail 24 that has arrived at the mailbox of the mail server via the communication unit 84.
When the e-mail 24 is received, the system password checking means 85 checks whether or not the e-mail 24 has a correct system password. The system password checking means 85 checks whether or not the e-mail 24 describes the correct system password used in the BGM playback system 10. If the correct system password is not described, the mail is discarded, and the command described in the electronic mail 24 is not analyzed and executed. Only when a correct system password is described, the player-specific password checking means 87 is activated to check the player-specific password.
[0053]
The player-specific password checking means 87 checks whether or not the e-mail 24 includes a player-specific password 99 corresponding to the BGM player 16.
If the correct password for each player assigned to the BGM player 16 is not described, the BGM player 16 sends an e-mail notifying the data transmitting apparatus 14 that the password for each player is incorrect. Send By receiving the e-mail, the data transmission device 14 allows the operator of the data transmission device 14 to recognize that the destination of the e-mail 24 describing the command was erroneously transmitted, and to write the command. It is possible to take measures such as reissuing the e-mail 24.
[0054]
If both the system password and the player-specific password are correct, the BGM player 16 executes a process based on the command or command sequence described in the e-mail 24.
If the command is for setting a playback program, the content playback control means 92 of the BGM player 16 accesses the content storage server 28 described in the received e-mail 24 and also writes the content in the e-mail 24. Following the storage path, the corresponding content is downloaded from the content storage server 28.
Further, the content reproduction control means 92 causes the reproduction program storage means 86 to store the reproduction program 80 described in the electronic mail 24 in order to execute the content.
[0055]
The content reproduction control means 92 reads out the reproduction program 80 from the reproduction program storage means 86 and executes it, thereby controlling the contents stored in the content storage means 88 to be reproduced in order based on the reproduction program 80. I do.
[0056]
According to the system password checking means 85, the BGM player 16 executes the command described in the e-mail 24 only when the correct system password is described in the e-mail 24 received by the BGM player 16. It is possible to prevent a malfunction from being caused by an e-mail from a third party due to wrong transmission or malicious intention.
[0057]
Also, according to the player-specific password checking means 87, the password is described in the e-mail 24 only when the e-mail 24 received by the BGM player 16 describes the player-specific password corresponding to the BGM player 16. In order to execute the command, it is possible to prevent the BGM player 16 having received the e-mail 24 from executing the command described in the e-mail 24 when the operator makes a mistake in setting the address by the address setting means. it can.
[0058]
The BGM playback system of the present embodiment employs both a system password and a player-specific password. Then, in the BGM player 16, the system password checking means 85 is performed before the player-specific password checking means 87. If the system password is wrong, the command is not executed and the player-specific password is wrong. By not replying to the e-mail to notify the BGM player of an incorrectly transmitted or malicious e-mail from a third party, the third party is notified that the password for each player is incorrect. An e-mail is not transmitted (replyed), and information on the BGM player is not given to the third party.
[0059]
By the way, for example, an administrator of the BGM reproduction system 10 may want to transmit a common command to a plurality of BGM players 16. For example, there is a case where the firmware of the BGM player is desired to be simultaneously upgraded by a command. In such a case, it is troublesome for the administrator to check the corresponding player-specific password for each BGM player 16 and create different e-mails.
[0060]
In order to solve this problem, each BGM player 16 is provided with a second corresponding player-specific password separately from the player-specific password, and the second player-specific password is shared among the BGM players 16. It should just be set to something. When the BGM player 16 checks the player-specific password described in the e-mail received by the player-specific password checking means 87, the player-specific password described in the e-mail matches one of the two player-specific passwords. Then, it is determined that the corresponding play-specific passwords match.
Thereby, when it is desired to send a command in which a common command is written to a plurality of BGM players 16, a second player-specific password common to each BGM player 16 is described, so that the same electronic mail can be used. BGM player 16 can execute a command.
However, since the second player-specific password is valid for any BGM player 16 of the BGM playback system 10, the second player-specific password has special authority for the playback system 10, such as the manager of the playback system 10. It is desirable to manage so that only the person can know.
[0061]
In the above-described embodiment, the content of the BGM player 16 is obtained by downloading the content from the content storage server 28. In this way, traffic is not congested, and even if the number of BGM players 16 increases, 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 content is attached to the e-mail 24 from the data transmission device 14 and directly delivered to the BGM player 16. It may be. In such a case, there is no need to describe the content identifier in the e-mail 24.
[0062]
