A long-awaited first industry standard for digital signage has been released by the Digital Signage Standards Committee at the Point-Of-Purchase Advertising International (POPAI), the not-for-profit industry association for marketing at retail.
The committee’s non-technical standard terminology document defines 10 key industry terms – and their synonyms, when appropriate.
The standards document also provides a Digital Signage Reference System – a diagram depicting a typical configuration and content flow of a multi-site digital signage network.
The signage process, as represented, begins in a network operations center, where content is authored and scheduled for a distribution server. Content can be distributed to the local point-of-presence via satellite, Internet, or virtual private network (VPN). Playout can occur via a single or multichannel player and drive one or multiple displays.
Members of the digital signage standards committee include Matt Nelson of Avocent, Jeff Porter of Scala, William Wu of DS-IQ, and Dustin Speer of Vestcom, along with Joe Finizio, POPAI’s vice president of member services.
The standards soon will be posted on many signage providers’ Web sites. The POPAI group is also seeking industry feedback on these initial standards.
