as a section of Program_and_System_Information_Protocol#What_PSIP_does, where it is mentioned. This is an ATSC standard for North American digital TV. This is the standard for encoding program listings for PSIP. It appears in https://books.google.com/books?id=K9N1TVhf82YC&pg=PA1411&lpg=PA1411&dq=PMCP+television&source=bl&ots=RtqcaG9-pv&sig=i3dF587Le5SRSmkzXWxJIkp6i6c&hl=en&sa=X&ved=0ahUKEwiw2uCbnJzWAhXIrFQKHRbSAUcQ6AEIRjAH#v=onepage&q=PMCP%20television&f=false National Association of Broadcasters Engineering Handbook, a standard reference. It is obviously verifiable and the standard itself, a consensus document among manufacturers, is a reliable, authoritative source for the standard. The content is verifiable, but there isn't a lot of outside commentary out there; it is part of the DTV plumbing. I don't know if there is enough out there to make for WP notability, but as an important part of PSIP, merging it in context in the PSIP article will preserve verifiable material per  and enrich the article
