DOC: Intro -- clearer wording
The paragraph that describes the pull processing seems slightly confusing, notably the follow-up processing is done by child nodes, not siblings. I attempted to use a more descriptive language

@ -144,12 +144,12 @@ Processing video (and audio) data can be conceived as a graph (more precisely
|
|||
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 at
|
||||
the top of the graph are where data input occurs. From there, the data moves on
|
||||
to the next nodes: the direct siblings of the root. Here, the video data is
|
||||
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.

The following figure depicts manipulating video data as a graph.
|
||||
Input data is retrieved from the source nodes, which are located at the
|
||||
top of the figure. From there, the data moves on to the next stage, where
|
||||
video and audio data and meta information is pre-processed. All the further
|
||||
operations on data can be represented by nodes, and data flows from one operation
|
||||
to the next along the nodes of the graph.
