~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Processing video (and audio) data can be conceived as a graph (more precisely
_directed acyclic graphs_). In this model of video processing, data flows
a _directed acyclic graph_). In this model of video processing, data flows
along the edges of the graph and is processed at the nodes.
The following figure depicts manipulating video data as a graph. The nodes of
the root of the graph is where data input occurs. From there, the data moves on
to the next nodes: the direct siblings of the root. Here, the video data
pre-processing occurs. All other operations on the data can be represented by

pre-processed. All other operations on the data can be represented by
nodes, and data flows from one operation to the next along the nodes of the
graph.
