2.3.7 Media Sequencer
The Media Sequencer is middleware software primarily used by control applications to
connect to for example render engines, newsroom systems and video server (e.g. Viz
One) systems.
More concrete the Media Sequencer is a framework for defining and executing media
elements. The media elements are defined in a tree-based schedule that the sequencer
interprets. The schedule is saved as an XML file (named default.xml). The XML file,
in short, contains the configuration settings and the playlists saved to it by the control
application.
The Media Sequencer’s scheduler has a high-resolution timer that manages a Virtual
Document Object Model (VDOM) that contains the schedule. The scheduler also
performs the actual execution of the schedule by interpreting elements describing
actions from the VDOM. The communication between end user products and the Media
Sequencer mostly goes through a protocol named TreeTalk.
