    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. The script is configured to cause the script to be interpreted by the application program to simulate a multi-threaded execution environment by: iteratively scheduling and performing a first simulated thread which involves decoding encoded video data received by the user-computing platform into decoded video data comprising one or more frame images; and iteratively scheduling and performing a second simulated thread which involves rendering the decoded video data by displaying the one or more frame images.

    Abstract: Methods are provided for encoding watermark information into media data containing a series of digital samples in a sample domain. The method 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; assigning a nominal bit value to each group according to a bit assignment rule, the bit assignment rule based on the energy values of the sections in the group; and assigning a watermark bit value to each group. 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.
