Problems solved by technology
[0008] Digital radio broadcast signals are subject to intermittent fading or blocking, which causes signal quality problems for signals received at digital radio broadcast receiver systems
In addition, there is some blocking that sufficiently blocks the broadcast signal from the receiver for a period of time and thus creates a gap in the reception of the broadcast signal

Embodiment Construction
[0043] A digital radio broadcast signal received at a digital radio broadcast receiver may include data containing one or more errors. The present inventors have developed novel systems and methods for mitigating the effects of these errors. Certain aspects of the systems and methods are implemented on the transmitter side, while other aspects are implemented on the receiver side. The methods described herein may be used to provide uninterrupted presentation of content (eg, any one or combination of audio, video, text, still images, multimedia, etc.) at a digital radio broadcast receiver.
[0044] Exemplary Digital Radio Broadcasting System
[0045] Figure 1-7 and its accompanying description herein provide a general description of an example IBOC system, example broadcast equipment structure and operation, and example receiver structure and operation. Figure 8-22 and its accompanying description herein provide a detailed description of an exemplary method for providing a...

Systems and methods for rendering content at a digital radio broadcast receiver system are described. A digital radio broadcast signal includes data for rendering content at a digital radio broadcast receiver. Digital radio broadcast signals are processed to determine whether data from digital radio broadcast transmissions contains data errors. Identify a portion of the data that contains data errors. A download request is sent to the computing system, wherein the download request requests duplicate data for the portion of the data that contains the data error. Repeated data for data portions containing errors is received at a digital radio broadcast receiver via wireless communication other than digital radio broadcast. Duplicate data is handled to provide uninterrupted presentation of content.
Description
[0001] This application claims priority to US Patent Application No. 14 / 580,920, filed December 23, 2014, the entire contents of which are incorporated herein by reference. technical field [0002] The technology described in this patent document relates generally to digital radio broadcasting, and more specifically to systems and methods for providing uninterrupted content presentation at digital radio broadcast receivers. Background technique [0003] Digital radio broadcasting technology delivers digital audio and data services to mobile, portable and fixed receivers. One type of digital radio broadcasting known as in-band on-channel (IBOC) digital audio broadcasting (DAB) uses terrestrial transmitters in the existing medium frequency (MF) and very high frequency (VHF) radio bands. HD Radio developed by iBiquity Digital Corporation TM technology is an example of an IBOC implementation for digital radio broadcast and reception. A characteristic of digital transmission sy...
