Abstract: Methods are provided for encoding watermark information into media data containing a series of digital samples in a sample domain. The methods involve: dividing the series of digital samples into a plurality of sections in the sample domain, each section comprising a corresponding plurality of samples; processing the corresponding plurality of samples in each section to obtain a single energy value associated with each section; grouping the sections into groups, each group containing three or more sections; for each group, assigning a nominal bit value according to a bit assignment rule, assigning a watermark bit value and comparing the watermark bit value to the nominal bit value. If the nominal bit value and the watermark bit value do not match, modifying one or more energy values of one or more corresponding sections in the group where re-application of the bit assignment rule would assign the watermark bit value to the group.

Abstract: Systems and methods render video content on different user-computing platform types. The method comprises: transmitting a script to the user-computing platform, the script comprising a non-compiled series of instructions which is configured to be interpreted by an application program operating on any one of the plurality of user-computing platform types; and using the application program to interpret the transmitted script by performing the series of instructions to thereby decode encoded video data accessible to the user-computing platform into decoded video data comprising one or more frame images without use of a previously compiled program module that is installed prior to the interpreting and without compiling the series of instructions prior to the interpreting.

Abstract translation: 提供了用于将水印信息编码到包含样本域中的一系列数字样本的媒体数据的方法。 该方法涉及：将一系列数字样本分成样本域中的多个部分，每个部分包括相应的多个样本; 处理每个部分中相应的多个样本以获得与每个部分相关联的单个能量值; 将部分分组成组，每组包含三个或多个部分; 对于每个组，根据比特分配规则分配标称比特值，分配水印比特值并将该水印比特值与标称比特值进行比较。 如果标称比特值和水印比特值不匹配，则修改组中一个或多个相应部分的一个或多个能量值，其中重新应用比特分配规则将水印比特值分配给组。
