Abstract: A server includes a communication port connected to an internet of things (IoT) cloud, at least one hardware processor connected to the communication port, and memory including instructions. The instructions, when performed by the at least one hardware processor, cause the at least one hardware processor to perform operations comprising identifying, to a client application of a separate computing device, one or more available radio broadcast stations available for transmitting a message in a radio broadcast signal to one or more end devices of an IoT; receiving a message from the client application indicating one or more of the available radio broadcast stations for transmitting the message; and sending the encrypted message via the IoT cloud to one or more other servers included with radio broadcast automation equipment of the one or more indicated available radio broadcast stations.

Abstract: A method comprises: generating a traffic sign message configured to configure an active traffic sign that is electronically configurable; encrypting the traffic sign message to produce an encrypted traffic sign message; sending the encrypted traffic sign message to a radio broadcast transmitter; and at the radio broadcast transmitter, transmitting the encrypted traffic sign message in a radio broadcast signal; and at the active traffic sign: receiving the radio broadcast signal and recovering the encrypted traffic sign message from the radio broadcast signal; decrypting the encrypted traffic sign message to produce the traffic sign message; and configuring the active traffic sign according to the traffic sign message.

Abstract: Methods and systems for advancing to another service from a plurality of services in a digital radio broadcast receiver are described. The methods and systems include the steps of receiving an instruction to advance to another service from a man-machine interface of the digital radio broadcast receiver, selecting an entry from a set of entries stored in a memory of the digital radio broadcast receiver responsive to the instruction, wherein each entry identifies a service, and wherein at least some of said services correspond to services identified as receivable, tuning to a first service identified by the selected entry, rendering content received on the first service at the digital radio broadcast receiver, and updating the set of entries stored in the memory of the digital radio broadcast receiver based on at least one criteria.
