ANSI SCTE 142:2017 pdf download.Recommended Practice for Transport Stream Verification.
This document is identical to SCTE 142 2009 except for informative components which may have been updated such as the title page. NOTICE text, headers and footers. No normative changes have been made to this document.
This Recommended Practice provides a common methodology for describing Transport Stream conformance criteria. This document explicitly describes the elements and parameters of SCTE 54 [2], along with ATSC A/53-3 [5] and A/65 [6] 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.
ANSI SCTE 142 is based upon an ATSC Recommended Practice, A/78A [16], which provided a complete foundation for this work. SCTE would like to express its gratitude to the ATSC for this pioneering work.
While the SCTE standards define strict limits for each parameter, in practice the severity of the error may depend upon the magnitude of the deviation. This document recommends severity levels associated with the ranges of’ deviation from ANSI SCTE 142 in these parameters.
