ANSI/SCTE 65 2016, "Service Information Delivered Out-of-Band for Digital Cable Television," defines SI tables delivered via an out-of-band path to support service selection and navigation by digital cable set-top boxes and other "digital cable-ready" devices. The SI tables defined in this standard are formatted in accordance with the Program Specific Information (PSI) data structures defined in MPEG-2 Systems.
ANSI/SCTE 214-1 2016, "MPEG-DASH for IP-Based Cable Services Part 1: MPD Constraints and Extensions," is part of a suite documenting usage of MPEG-DASH in IP-based cable networks. It specifies restrictions on MPD and codecs that apply to both MPEG-2 TS and ISO-BMFF segments. Thus, DASH/TS profile is a combination of part 1 (this standard) and part 2 (which defines aspects specific to MPEG-2 TS), and, analogously, DASH/FF profile is a combination of part 1 and part 3 (which defines aspects specific to ISO-BMFF). The DASH/TS profile is also very similar to the adaptive transport stream source description defined in SCTE 215.
ANSI/SCTE 214-2 2016, "MPEG-DASH for IP-Based Cable Services Part 2: DASH/TS Profile," defines DASH/TS - a profile of MPEG DASH which uses MPEG-2 TS segments. In addition, this profile integrates elements of SCTE specifications that define media formats and digital program insertion. This profile is based on of the philosophy of DASH MPEG-2 TS Simple Profile and is similar in its approach to the Common ISO-BMFF Profile.
