The American National Standards Institute (ANSI) recently announced that it has approved the following SCTE standards:

ANSI/SCTE 215-1 2020 - HEVC Video Constraints for Cable Television Part 1- Coding

This document defines the coding constraints on ITU-T Rec. H.265 | ISO/IEC 23008-2 video compression (hereafter called "HEVC") for Cable Television. In particular, this document describes the coding of a single HEVC coded video elementary stream carried in MPEG-2 transport (ISO/IEC 13818-1) for linear delivery systems supporting ad insertion services. Beyond linear delivery with DPI, signaling is provided for segmentation of content for xDVR applications.

ANSI/SCTE 215-1-1 2020 - HEVC Video Constraints for Cable Television Part 1-1 HDR10 Coding

This document defines the additional coding constraints on SCTE 215-1 HDR video streams using an HDR10 format.

ANSI/SCTE 250 2020 - Real-time Event Signaling and Management API

This document details the interfaces between a Signal Acquisition System (SAS) and a Signal Decision System (SDS) in order to support signal and manifest processing. The APIs support synchronous signal processing, asynchronous signal processing, and processing of both linear and file-based content.
