The American National Standards Institute has approved two SCTE standards on streaming video.
ANSI/SCTE 217 2017, "MPEG DASH Reference Architecture for IP-based Cable Services," is intended to serve as informational background to a suite of specifications that define the usage of MPEG-DASH in cable networks. It introduces adaptive bitrate streaming as a general service and defines reference architecture in which content processing components, flows of process, use cases and scope definition of each part of other relevant documents are described.
ANSI/SCTE 223 2017, "Adaptive Transport Stream," 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.
