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 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.

A broadcasting method includes: using a first transmitter to send a signal including a plurality of frames of data synchronized with respect to a first GPS pulse signal, receiving the signal at a first remote transmitter, synchronizing the frames to a second GPS pulse signal at the first remote transmitter, and transmitting the synchronized frames from the remote transmitter to a plurality of receivers. A system that implements the method is also provided.
