Call method, copyright protection system and call system
First Claim
1. A call apparatus for bidirectional communication with voice for dialog over a network, comprising downloading means for downloading a sound source data file for the music, as the sound sustained for several minutes as a time unit, or a sound source data file for the effect sound, sustained for several seconds as a time unit, from a server connected to the network;
- storage means for storage of said sound source data file, downloaded by said downloading means;
hash value calculating means for calculating a hash value in a predetermined folder in said storage means; and
setting means for setting said hash value, calculated by said hash value calculating means, as the system information;
wherein the copyright of the sound source data file is protected based on said hash value as set by said setting means.

Abstract
The copyright or the use right is sometimes prescribed in a sound source data file used as BGM, so that, in a sound source data file, acquired by a user, copying and re-distribution need to be suppressed without detracting from its serviceability. To this end, a VoIP client writes a downloaded sound source data file in a prescribed folder in a HDD forming an external storage device. When the writing is finished regularly, a hash value in the folder is calculated. The so calculated hash value is set in the user-oriented system information in the external storage device. When the VoIP client is booted for VoIP call, a hash value in a prescribed folder in the external storage device is calculated, and the so calculated hash value is compared to the hash value stored as the system information. If the result of comparison indicates that the hash value calculated is equal to the hash value stored, the sound source data file, stored in the prescribed area in the external storage device, is displayed on the GUI.

5. A call system comprising
a data file server for storage of a sound source data file for the music, as the sound sustained for several minutes as a time unit, or a sound source data file for the effect sound, sustained for several seconds as a time unit, and for supplying the sound source data file, responsive to a request from a client; -
said client supplied with a desired sound source data file from said data file server and having bidirectional communication with voice for dialog over a network; and
a control server for controlling bidirectional communication by said client;
whereinsaid data file server stores, in storage means, the user information of a client in terms of a sound source data file, requested by said client, as a unit;
said control server sends the authentication information, sent by said client, to said data file server;
said control server sends the authentication information, sent by said client, to said data file server;
said data file server retrieves the user information, stored in said storage means, based on said authentication information from said control server, to transmit a list of available sound source data files through said control server to said client; and
whereinsaid client retrieves a prescribed area in said storage device to which said sound source data files are sent, based on said list of the available sound source data files received, to display only coincident sound source data files in a visual interface. - View Dependent Claims (6, 7)

8. A copyright protection method carried out in a call system including a data file server for storage of a sound source data file for the music, as the sound sustained for several minutes as a time unit, or the effect sound, sustained for several seconds as a time unit, and for supplying the sound source data file, responsive to a request from a client;
-
said client supplied with a desired sound source data file from said data file server and having bidirectional communication with voice for dialog over a network; and
a control server for controlling bidirectional communication by said client;
said method comprising the steps ofsaid data file server storing, in storage means, the user information of a client in terms of a sound source data file, requested by said client, as a unit;
said control server sending the authentication information, sent by said client, to said data file server;
said data file server retrieving the user information, stored in said storage means, based on said authentication information from said control server, to transmit a list of the available sound source data files through said control server to said client; and
said client retrieving a prescribed area in said storage device where said sound source data files are stored, based on said list of the sound source data files received, to display only coincident sound source data files in a visual interface. - View Dependent Claims (9, 10)
