Abstract

The system and method creates a broadcast tree comprising a hierarchy of broadcast constituents, each constituent represented as a node in the tree. The tree includes at least two nodes representing at least two of the following constituents arranged in accordance with the following hierarchical order; channel, schedule, program, pod and element, wherein the channel is the highest order constituent and the element is the lowest order constituent and wherein each higher order constituent can be composed of one or more constituents of the same or lower order. Associations are provided between constituents to be used to identify the sequence the constituents are played in order to generate a broadcast. These associations identify the paths to be taken from a higher order node to a lower order node. Thus, to generate a broadcast, the tree is traversed beginning at the highest order constituent, and for each higher order constituent, the associations among lower order constituents of the same order are evaluated to determine the sequence the lower order constituents are to be played.
