Appl. No.:

12/032011

Inventors:

Russell Iannuzzelli - Bethesda MD, US
Stephen Douglas Mattson - Felton PA, US

Assignee:

iBiquity Digital Corporation - Columbia MD

International Classification:

H04J 3/00

US Classification:

370476, 370389, 370465, 375295, 375219, 375220

Abstract:

A data unit for transmitting data in a digital broadcasting system includes a first payload field, and a first byte code field having a value indicating an offset of data in the first payload field with respect to an absent value. A method for formatting the data unit includes: providing data for a payload field for a data unit, wherein the data includes an absent byte value, determining an offset between an absent byte value and other data in the payload field, shifting the data in the payload field by the offset to produce shifted bytes, and inserting a byte code in the data unit, wherein the byte code indicates the offset. A transmitter for transmitting the data units, and a receiver for receiving the data units are also provided.

H04J 3/06
H04N 7/12

US Classification:

370252, 370503, 3484231, 3484254

Abstract:

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.

International Classification:

H04B 1/707

US Classification:

375145

Abstract:

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.

US Classification:

714807, 714E1103

Abstract:

A method for transmitting data between components of a digital broadcasting system includes: receiving payload data, adding a content layer header to the payload data to form a content layer data frame, adding a transmission and authentication layer header and a cyclic redundancy check field to the content layer data frame to form a transmission and authentication layer data frame, adding an application framing layer header to the transmission and authentication layer data frame to form an application framing layer data frame, and transmitting the application framing layer data frame to a destination component.

International Classification:

H04J 318

US Classification:

370477, 370468, 370204, 370312, 370326

Abstract:

A method for transmission of compressed data for a digital audio broadcasting system comprises the steps of producing digital information representative of an audio signal; estimating the number of bits to be allocated to the digital information in a modem frame; encoding the digital information within the estimated number of bits to produce encoded data; removing selected bits from the encoded data; adding bits corresponding to digital messages to the encoded information to form a composite modem frame; formatting the composite modem frame bits to produce formatted composite modem frame bits; and transmitting the formatted composite modem frame bits. The invention also encompasses transmitters that perform the method.
