Abstract: In order to protect against unauthorized duplication of a library file, or the like, according to the present invention, an executable module is generated. The executable module is generated by generating, with decryption of an encrypted protective object, a protective object containing a procedure for terminating a process operation due to invalid relationship between a first protect code and a second protect code contained in the executable module, linking the resultant decrypted protective object with other object, and writing a protect code. Then, the decrypted protective object is deleted after linking with the other object.

Abstract: Digital sound data is encrypted and recorded in a recording medium 200. Information 212 required for decoding the encrypted digital sound data 220 is recorded in a program 211 for controlling the reproduction of sound data separately from the digital sound data 220. This can prevent PCM sound data recorded in the recording medium as a part of a content, from being reproduced separately from the content.

Abstract: Image processing means comprises image converting means for converting manipulation data inputted by a user with a manual controller or a mouse into an input pattern image, geometric shape judging means for determining a type of an input geometric shape indicated by the input pattern image based on a plurality of geometric shape judging criterion, image appearance displaying means for displaying a symbolic image corresponding to the type of the input geometric shape on the monitor, and image form determining means for determining a form of the symbolic image displayed on the monitor. The image form determining means comprises accuracy calculating means for determining accuracy of the input geometric shape based on the number of deviations from an allowable range of a judging criteria used in judgment for the determined type of the input geometric shape, and modification displaying means for modifying the form of the symbolic image displayed on the monitor based on the accuracy of the input geometric shape.

Abstract: A first information processing apparatus extracts information expressing a characteristic of input information, changes the input information to character data, subjects the character data to prescribed processing based on the information expressing a characteristic, and sends the character data subjected to the prescribed processing to a network. A second information processing apparatus receives character data via a network, extracts prescribed information from the character data, changes the character data to other information, and subjects the character data or other information to prescribed processing based on the extracted prescribed information. The communication using the first and second information processing apparatuses is, for example, rich and enjoyable, and accompanied by, for example, emotions. The first and second information processing apparatuses enable smooth communication, without an increase in the amount of information that is mutually exchanged.

Abstract: It is an object of the present invention to provide a method of reproducing stream data according to which the order of reading stream data such as sound data can be controlled. The sound data reproducing processing is implemented by the reading processing portion 200 and the output processing portion 210. The reading processing portion 200 sequentially reads the sound data stored in a CD/DVD 220 to the buffer 161 according to the branch definition file stored in the CD/DVD 220, while the output processing portion 210 sequentially transfers the sound data read out to the buffer 161 to the sound reproducing processor (SPU) 140.

Abstract: It is an object of the present invention to provide a method of reproducing stream data according to which the synchronization between the reproduction of the stream data such as sound data and the operation of an application can be easily achieved.
