摘要： The invention concerns a method for distributing a nominal audiovisual stream to a recipient device, the nominal audiovisual stream comprising nominal coefficients; the method including; a step which consists in modifying, in the nominal audiovisual stream at least one nominal coefficient among said nominal coefficients so as to generate a modified main stream; generating a complementary information such that the nominal audiovisual stream is capable of being implemented based on said complementary information and on the modified main stream. The method is characterized in that it includes steps which consist in: applying a plurality of methods for protecting the complementary information to generate multiple protected complementary data, each of the respective protected complementary data enabling the nominal stream of the main stream to be implemented upon application of an access method compatible with the protection method which has been used to protect it; transmitting to the recipient device the modified main stream and the multiple protected complementary data.

摘要： The invention relates to a method for distributing a marked video sequence (106) from a nominal video sequence (1), said nominal video sequence having a nominal content, in which a first modified flow (101) having a modified content different from the nominal content is generated, and a second marked complementary flow (103) containing marked complementary digital data is generated. Said first modified flow and said marked complementary information are transmitted so as to enable the reconstruction at the addressee's equipment of said marked audiovisual sequence (106). A marking operation of said nominal audiovisual sequence (1) is carried out in order to determine a marked audiovisual sequence (106, 111) having a marked content. The method further comprises determining a difference between said marked content on the one hand and said modified content or said nominal content on the other hand. All the marked complementary digital information (103) is a function of said difference.
摘要翻译：本发明涉及一种用于从标称视频序列（1）分发标记视频序列（106）的方法，所述标称视频序列具有标称内容，其中具有不同于标称值的修改内容的第一修改流（101）产生内容，并且生成包含标记的互补数字数据的第二标记的互补流（103）。发送所述第一修改流和所述标记的补充信息，以便能够在收件人的设备处重建所述标记的视听序列（106）。执行所述标称视听序列（1）的标记操作，以便确定具有标记内容的标记的视听序列（106,111）。该方法还包括另一方面确定所述标记的内容与所述修改的内容或所述标称内容之间的差异。所有标记的互补数字信息（103）是所述差值的函数。

摘要： The invention relates to a method for the secured distribution of digital data transmitted to a client terminal (11), said digital data (1) having a first digital format of a non-audiovisual type, wherein said method uses a protection device (4) capable of protecting data (3; 31) having a second digital format and of transmitting said data to said client terminal (11). According to the invention, said second format is of the audiovisual type, and the method comprises a conversion step (2) for converting the digital data (1) having said first digital format into said second format.
摘要翻译：本发明涉及一种用于安全分发发送到客户终端（11）的数字数据的方法，所述数字数据（1）具有非视听类型的第一数字格式，其中所述方法使用保护装置（4）能够保护具有第二数字格式的数据（3; 31）并将所述数据发送到所述客户终端（11）。根据本发明，所述第二格式是视听类型，并且该方法包括用于将具有所述第一数字格式的数字数据（1）转换成所述第二格式的转换步骤（2）。
