A FEDERATED DATA DISTRIBUTION SYSTEM FOR ACCURATE, UPDATED, COINCIDENT DELIVERY OF PROGRAM METADATA TO END USER DEVICES

摘要

We introduce MetaPub, a metadata distribution system for public radio. MetaPub is a federated clearinghouse for story level, time scheduled public media metadata (text, images, links, and background information), supporting distribution to HD radio receivers, mobile radio apps, web streaming systems, and RDS. MetaPub is designed for the unique needs of public radio: breaking news, story-telling, live performances, art, music, and other cultural programming. Currently, most delivery platforms for public radio do not provide information beyond station name, logo and the name of the program currently on air. MetaPub provides a framework for the next generation; gathering fine-grained per-story and per-piece metadata from existing producer databases, integrating local station information, and distributing to metadata enabled devices and radios.
