Patent ID: 8660128

Claim:
A processor-implemented method of scheduling and delivering content for digital radio broadcast transmission comprising: a. receiving a request to render first media content in synchronization with second media content, wherein the first media content is directed along a first signal path through a digital radio broadcast transmitter and the second media content is directed along a second signal path through the digital radio broadcast transmitter, and wherein the request includes a requested render time of the second media content by a digital radio broadcast receiver; b. receiving a request to render third media content asynchronously at the digital radio broadcast receiver; c. receiving a plurality of content requests from an importer, each content request including a value corresponding to a time at which media content following the second signal path that is delivered responsive to the content request would be rendered by the digital radio broadcast receiver; d. delivering the first media content to the importer responsive to at least one of the content requests when the value of the content request corresponds to the render time of the second media content, such that the first media content can be rendered synchronously with the second media content by the digital radio broadcast receiver; and e. delivering the third media content to the importer responsive to at least one of the content requests such that the third media content can be rendered asynchronously by the digital radio broadcast receiver.
