The SCTE has approved two streaming video standards.
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 (ABR) 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.
SCTE 223 2017, "Adaptive Transport Stream," is intended to address a variety of adaptive streaming wire formats. Some are based on an MPEG-2 Transport Stream container such as HLS (HTTP Live Streaming: Apple) and others on a fragmented MP4 container such as HSS (HTTP Smooth Streaming: Microsoft) and HDS (HTTP Dynamic Streaming: Adobe); whereas DASH (Dynamic Adaptive Streaming over HTTP: MPEG) supports both containers. While different, they utilize common video and audio compression formats; namely: ISO/IEC 14496-10 (AVC) and ISO/IEC 14496-3 (AAC). Additional audio formats, such as Dolby Digital Plus and DTS-HD, may also be supported by these or a subset of these adaptive bitrate (ABR) formats.
