Publication number: 20230422028Abstract: 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.Type: ApplicationFiled: October 7, 2021Publication date: December 28, 2023Applicant: iBiquity Digital CorporationInventors: Ashwini Pahuja, Catherine P.

Patent number: 10177729Abstract: Systems and methods to process a digital audio broadcast signal having a plurality of digital audio signals can be implemented in a variety of applications. The digital audio broadcast signal having a main program service and a set of supplemental program services can be received at a digital audio system and processed to provide an audio signal to a set of speakers. The processing can include calculation of audio levels of audio signals of the main program service and the supplemental program services. One of the services can be selected with the audio signal of the selected service adjusted based on the calculated level of the selected service and a reference signal, prior to sending the audio signal to the set of speakers. In various embodiments, the reference signal can be an analog audio signal in the digital audio broadcast signal. Additional apparatus, systems, and methods are disclosed.Type: GrantFiled: February 19, 2018Date of Patent: January 8, 2019Assignee: Ibiquity Digital CorporationInventor: Ashwini Pahuja
