The SCTE has approved one ad insertion recommended practice and two MPEG-4 standards.
The SCTE has approved SCTE 194-2 2014, "DTS-HD AUDIO SYSTEM - Part 2: Constraints for Carriage over MPEG-2 Transport." The document describes the carriage of DTS-HD audio in MPEG-2 systems, as well as the descriptor necessary to signal DTS-HD audio. Multiplexing and transport for cable using MPEG-2 systems are defined in SCTE 54 [5]. Coding constraints for DTS-HD audio elementary streams are defined in SCTE 194-1 [4].
