Using web-based protocols to assist graphic presentations in digital video playout

Abstract:

Playing out digital video with customized graphics whose appearance and operation are specified by a graphics template expressed using one or more web-based protocols. One or more software modules, executing on a media server, identify, for a particular digital video, a markup language document which describes a customized appearance of one or more graphics to be incorporated into a presentation of particular digital video. The markup language document may be an Extensible Markup Language (XML) document or a HyperText Markup Language (HTML) document. The media server plays out the particular digital video with the one or more graphics in accordance with the markup language document. An HTML rendering engine, executing on the media server, may pass through one or more audio streams to be incorporated into an output stream used in playing out the particular digital video without re-encoding the one or more audio streams.
