20090061763 | Digital radio broadcast receiver, broadcasting methods and methods for tagging content of interest - A method for specifying content of interest using a digital radio broadcast receiver is described. A digital radio broadcast signal includes first audio content and first program data, wherein the first program data includes information identifying a first item, and includes second audio content and second program data, wherein the second program data includes information identifying a second item. A user command entered at a user interface during reception of audio content is registered, indicating a user's interest in either the first or second audio content. It is determined whether there is an ambiguity in the content of interest. If there is an ambiguity, a first data structure is stored for the first audio content, and a second data structure is stored for the second audio content. The first data structure includes the information identifying the first item, and the second data structure includes the information identifying the second item. | 03-05-2009 |
20090086833 | Radio Signal Generator - A signal generator includes a memory for storing content information in the form of vectors including in-phase and quadrature elements of an orthogonal frequency division multiplexing waveform, a processor for converting the vectors to a radio frequency signal, and a logic device for controlling the operation of the memory and the processor. The in-phase and quadrature elements represent baseband content of the orthogonal frequency-division multiplexing waveform. | 04-02-2009 |
20100265398 | 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 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. | 10-21-2010 |
20110039492 | Digital radio broadcast receiver, broadcasting methods and methods for tagging content of interest - A digital radio broadcast system includes a processing system that receives first audio content, first program data identifying a first item for the first audio content, second audio content, and second program data identifying a second item for the second audio content such that a start of the first program data is received at the processing system within 0.5 seconds of a start of the first audio content. A digital radio broadcast signal including the audio content and the program data is processed for digital radio broadcast transmission via a transmitter. The processing system stops delivery of the first program data to the transmitter upon receipt of the second program data, the first program data thereby being truncated, and begins delivery of the second program data to the transmitter. A digital radio broadcast receiver can tag content of interest based on a user command registered at the receiver. | 02-17-2011 |
20110090897 | 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. | 04-21-2011 |
20120162512 | 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 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. | 06-28-2012 |
20120189069 | 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 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. | 07-26-2012 |
