    Abstract: Methods are provided for encoding watermark information into media data containing a series of digital samples in a sample domain. The methods involves: 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 are provided for cross-platform rendering of video content on a user-computing platform that is one type of a plurality of different user-computing platform types. A script is transmitted to the user-computing platform and is interpreted by an application program compiled to operate on any one of the plurality of user-computing platform types. A series of frame images is encoded to provide the encoded video data. Encoding the frame images comprises encoding the frame images into a content-transfer format whereby the content-transfer encoded frame images can be passed by a script interpreter interpreting the script to the application program. The encoded video data is transmitted to the user-computing platform. The script is further configured to cause the script to be interpreted by the application program to: decode the transmitted encoded video data into decoded video data comprising the content-transfer encoded frame images; and render the decoded video data by displaying the frame images.

The methods also involve, for each group, comparing the watermark bit value to the nominal bit value and, if the nominal bit value and the watermark bit value of the watermark information bit do not match, modifying one or more energy values of one or more corresponding sections in the group such that re-application of the bit assignment rule would assign the watermark bit value to the group. The bit assignment rule may comprise: a categorization rule for categorizing each group into one of a plurality of categories; and for each category, a unique category bit assignment rule for assigning a nominal zero bit value or a nominal one bit value to each group.
