Displaying interconnects having an appearance indicating data characteristics

A method for displaying interconnects that connect nodes of a process tree displayed in a multimedia application of a computer system the method comprising:

• displaying a plurality of nodes of the process tree, each node representing one of a multimedia item and a function being performed on at least one multimedia item;
• and
• displaying a plurality of interconnects that indicates a flow of data through the process tree, each interconnect representing data being passed between a pair of nodes that the interconnect connects and having
• a particular graphical appearance that indicates one or more characteristics of the data being passed between the pair of nodes that the interconnect connects.

A non-transitory computer readable medium storing a computer program executable by a processor, the computer program comprising sets of instructions for:

• displaying a plurality of nodes of a process tree that indicates a flow of data propagated through the plurality of nodes, each node representing one of a multimedia item and a function being performed on at least one multimedia item;
• and
• displaying a plurality of interconnects that connect the nodes of the process tree, each interconnect displayed in one or more graphical appearances and representing data being propagated between a pair of nodes that the interconnect connects,
• wherein first and second graphical appearances of a first interconnect indicate first and second characteristics of the data represented by the first interconnect,
• wherein first and second graphical appearances of a second interconnect indicate first and second characteristics of the data represented by the second interconnect,
• wherein each of the first and second graphical appearances of the first and second interconnects are different from each other in order to indicate different first and second characteristics of the data represented by the first and second interconnects.

A computer readable medium storing a computer program comprising a graphical user interface (“GUI”), said GUI comprising:

• a display area for displaying a process tree of a media application of a computer system, the process tree comprising a plurality of interconnects connecting a plurality of nodes of the process tree, each interconnect representing data being passed between a pair of nodes, each node representing a multimedia item or a function performed on a multimedia item;
• a display area for displaying a plurality of selectable graphical display appearances, each graphical display appearance indicating a different characteristic of data;
• and
• a set of controls for receiving a selection of one or more graphical display appearances to apply to each interconnect that represents data with the characteristics indicated by the selected graphical appearances, wherein the selection of a particular graphical display appearance is applied to a plurality of interconnects when the plurality of interconnects represent data having the particular characteristic of data indicated by the particular graphical display appearance.
