An apparatus comprises a digital input port configured to receive digital audio packets of main program service (MPS) audio; a modem operatively coupled to the digital port; an analog input port configured to receive an audio engineer society format (AES) audio signal that is a digitized version of the analog signal component of the frequency modulation (FM) hybrid radio signal; and an alignment unit configured to time-align the AES audio signal with the digital audio packets at the modem; wherein the modem is configured to generate the FM hybrid radio signal using the digital audio packets and the time-aligned AES audio signal.

Systems and methods are described for rendering content at a digital radio broadcast receiver system. A digital radio broadcast signal comprises data for rendering content at the digital radio broadcast receiver. The digital radio broadcast signal is processed to determine whether the data from the digital radio broadcast transmission contains a data error. A portion of the data containing the data error is identified. A download request is transmitted to a computing system, where the download request requests duplicate data for the portion of the data containing the data error. The duplicate data is received at the digital radio broadcast receiver for the portion of the data containing the error via other wireless communication other than the digital radio broadcast. The duplicate data is processed to provide an uninterrupted rendering of the content.

Systems and methods for digital radio broadcast with cross platform reception

A translator includes: an input configured to receive a bit stream having a plurality of digitally encoded contents and control information; processing circuitry configured to select one of the digitally encoded contents, to use the selected digitally encoded content to produce an analog modulated signal, to use the digitally encoded contents to produce a digitally modulated signal, and to combine the analog modulated signal and the digitally modulated signal to produce a hybrid signal; and an output configured to output the hybrid signal. A method performed by the radio signal translator is also provided.

Apparatus and method for distributing content from an HD radio system

A data link manager includes a User Datagram Protocol (UDP) receiver for receiving HD Radio broadcast equipment communication protocol (HDP) data or non-HD Radio broadcast equipment communication protocol (non-HDP) data using a User Datagram Protocol/Internet Protocol (UDP/IP) protocol; a Transmission Control Protocol (TCP) receiver; and a router for receiving data from the UDP receiver and the TCP receiver, for searching for a destination route in a routing table, and for forwarding the data received from the from the UDP receiver and the TCP receiver to an identified destination route.

Broadcast equipment communication protocol

Systems, methods, and processor readable media are disclosed for encoding and transmitting first media content and second media content using a digital radio broadcast system, such that the second media content can be rendered in synchronization with the first media content by a digital radio broadcast receiver. The disclosed systems, methods, and processor-readable media determine when a receiver will render audio and data content that is transmitted at a given time by the digital radio broadcast transmitter, and adjust the media content accordingly to provide synchronized rendering. In exemplary embodiments, these adjustments can be provided by: 1) inserting timing instructions specifying playback time in the secondary content based on calculated delays; or 2) controlling the timing of sending the primary or secondary content to the transmitter so that it will be rendered in synchronization by the receiver.

Systems and methods for transmitting media content via digital radio broadcast transmission for synchronized rendering by a receiver

Systems, methods, and processor readable media are disclosed for scheduling and delivering content for digital radio broadcast transmission. To overcome the inefficiencies of conventional scheduling and delivery techniques, the present disclosure describes a novel multiport synchronous-asynchronous client for receiving content from multiple sources and then scheduling and delivering that content to an importer.

Systems and methods for a multiport synchronous-asynchronous client for scheduling and delivering content for digital radio broadcast transmission

Systems, methods, and processor readable media are disclosed for encoding and transmitting first media content, second media content and triggering instructions to a digital radio broadcast receiver such that the triggering instructions arrive for immediate execution to trigger immediate rendering of the second media content in synchronization with the first media content.
