ANSI SCTE 223:2018 pdf download.Adaptive Transport Stream.
ANSI SCTE 223 describes the requirements and constraints on a single program transport stream (SPTS) that allow it to be used as an Adaptive Transport Stream, including stream conditioning and signaling of segment boundary points. Typically, multiple ATSs will be generated from a single input and sent to a packager, recorder or other device. The EBP structure can be inserted at the time of encoding or added during the transcoding process. This specification does not describe how an ATS is stored or how it may be converted to target delivery formats.
This document describes the wrapping, chunking. and conditioning of packetized elementary streams carried over MPEG-2 TS. These elementary streams are codec independent and could carry AVC, IIEVC, or even MPEG-2 video. Reference is made to SCTE 128 [31[33] to be compliant with MPEG-2 Systems layer constraints on the use of adaptation field public data.
These created ATS streams are then sent to a packager (also called a fragmentor or encapsulator) directly or stored to be sent to an packager upon request at a later time. Upon receiving such streams, an packager then processes these streams with EBP data and produces chunks according to the one or more adaptive streaming encapsulating technologies.
