6. Overview
A Traffic System shall communicate, through a Schedule File, the spots to be played by the Ad Insertion System in response to various SCTE 35 [1] Cue Messages. The Ad Insertion System shall communicate, through a Verification File, which spots were played (or attempted to play), which failed to play (due to an error or due to no matching Cue Message), and any Cue Messages that were received but not acted upon. This document defines the necessary information to communicate both the scheduling of Spots from a Traffic System to an Ad Insertion System and the return path verifications in accordance with the various Tiers of service described in SCTE 118-1 [9]. Additionally, it details the file format for communication between a Traffic System and an SCTE 35 compliant Ad Insertion System. The schedule and verification files between the Traffic System and the Ad Insertion System are contained within Extensible Markup Language (XML) documents.
