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.
