This Recommended Practice provides a common methodology for describing Transport Stream conformance criteria. This document explicitly describes the elements and parameters of SCTE 54 , along with ATSC A/53-3  and A/65  that should be verified in an SCTE Transport Stream for it to be considered a proper emission. It does not cover RF, captioning or elementary streams.
This Standard is based upon an ATSC Recommended Practice, A/78A , which provided a complete foundation for this work. SCTE would like to express its gratitude to the ATSC for this pioneering work.
