    • PROBLEM TO BE SOLVED: To provide a method for preventing a data file from being copied for the purpose of transmission of information.
      SOLUTION: A method for transmitting a data file, which includes a stream of blocks obtained by encoding information content and has a format suitable for transmission, has a step in which DSV data patterns are integrated into the data file and a step in which the data file is transmitted via a network to a receiver, after the DSV data patterns are integrated, so as to reproduce the data file after the transmission. The DSV data patterns are selected, so that the data file may not be surely read out, when the data file is written to an optical disk, and are selectively arranged in a block regarded as an audio block which does not include the audio information content of the data file.

    • 要解决的问题:提供一种用于防止数据文件被复制以传送信息的方法。 解决方案:一种用于发送数据文件的方法,其包括通过对信息内容进行编码获得并具有适合于传输的格式获得的块的流,具有将DSV数据模式集成到数据文件中的步骤, 在DSV数据模式被集成之后,数据文件经由网络传送到接收器,以便在传输之后再现数据文件。 选择DSV数据模式,使得当数据文件被写入光盘时可能不能确定地读出数据文件,并且被选择性地排列在被视为不包括音频信息内容的音频块的块中 的数据文件。 版权所有(C)2009,JPO&INPIT
