Abstract: A method for providing extended control of media displayed on individual and groups of digital signs for use in near realtime scenarios by leveraging the short message service (SMS) as a transport mechanism to enable immediate temporary or permanent changes to displayed media shown on digital signage. Each SMS message utilizes command codes and variable arguments to query for information to be returned or indicate actions to be performed, providing a subset of the data and control mechanisms exposed by the digital signage management service. SMS endpoints are authenticated against a whitelist also containing a list of valid digital signage management groups with associated message routing information. Data requests require no additional validation, while action requests include a secondary verification as a protection against caller ID spoofing.
