The American National Standards Institute has approved two SCTE standards, one on coaxial cable and the other on ad insertion.
ANSI/SCTE 15 2016, "Specification for Trunk, Feeder and Distribution Coaxial Cable," applies to material, electrical and mechanical properties of 75 ohm coaxial cables used to distribute RF, digital signals and power as applicable.
ANSI/SCTE 130-5 2016, "Digital Program Insertion- Advertising Systems Interfaces Part 5- Placement Opportunity Information Service," defines the messaging protocol for the POIS consistent with other parts of the SCTE 130 standard. A POIS, or a repository to which it has access, stores and maintains descriptions of content placement opportunities (typically for advertisements), and the interface supports query and notification operations for those opportunities. The specification defines a standardized interface for accessing the placement opportunity information known to a POIS.
Both standards are available at http://www.scte.org/SCTE/Standards/Download/SCTE/Standards/Download_SCTE_Standards.aspx.
