Abstract

Systems and methods are described for rendering content at a digital radio broadcast receiver system. A digital radio broadcast signal comprises data for rendering content at the digital radio broadcast receiver. The digital radio broadcast signal is processed to determine whether the data from the digital radio broadcast transmission contains a data error. A portion of the data containing the data error is identified. A download request is transmitted to a computing system, where the download request requests duplicate data for the portion of the data containing the data error. The duplicate data is received at the digital radio broadcast receiver for the portion of the data containing the error via other wireless communication other than the digital radio broadcast. The duplicate data is processed to provide an uninterrupted rendering of the content.

First claim

1 . A computer-implemented method for rendering content at a digital radio broadcast receiver system, the method comprising:
receiving a digital radio broadcast signal via digital radio broadcast transmission, the digital radio broadcast signal comprising data in a specified format for rendering content at the digital radio broadcast receiver; processing the digital radio broadcast signal to determine whether the data from the digital radio broadcast transmission contains a data error and identifying a portion of the data containing the data error; transmitting a first notification to a computing system, the first notification being effective to cause the processing of duplicate data for the portion of the data containing the data error, receiving the duplicate data at the digital radio broadcast receiver for the portion of the data containing the error via other wireless communication other than the digital radio broadcast transmission based on the first notification, wherein the duplicate data comprises the data in the specified format of the digital radio broadcast signal transmitted by the digital radio broadcast transmitter system; and selecting the duplicate data instead of selecting the portion of the data that contains the data error to provide corrected data, and processing the corrected data at the digital radio broadcast receiver to provide an uninterrupted rendering of the content.

2 . The method of claim 1 , wherein the content is an audio program, wherein the data from the digital radio broadcast transmission comprises audio data, wherein the digital radio broadcast signal includes program data identifying the audio program, and wherein the duplicate data is received without receiving data via the other wireless communication for the entire audio program.

3 . The computer-implemented method of claim 1 , wherein the duplicate data includes a first data structure that is generated by the digital radio broadcast transmitter system, and wherein an identical copy of the first data structure is broadcast by the digital radio broadcast transmitter system for receipt at the digital radio broadcast receiver.

4 . The computer-implemented method of claim 3 comprising:
downloading the first data structure from a file server via an Internet protocol, wherein the first data structure is encapsulated in a file to facilitate the downloading of the first data structure via the Internet protocol.

5 . The computer-implemented method of claim 1 comprising:
determining, from the digital radio broadcast signal, a subject matter of the content, a name of a person associated with the content, a song title associated with the content, or an album title associated with the content;
transmitting a second notification to a second computing system, the second notification effective to cause processing of second data comprising content that is related to the determined subject matter, name, song title, or album title; and
receiving the second data at the digital radio broadcast receiver via the other wireless communication based on the second notification.

6 . The computer-implemented method of claim 5 , wherein the content that is related to the determined subject matter, name, song title, or album title comprises information related to merchandise, information related to concert tickets, an image, a video, or biographical information.

7 . The computer-implemented method of claim 1 comprising:
receiving, via the other wireless communication, data comprising a list of radio stations and associated broadcast frequencies, wherein each radio station of the list is associated with one or more digital radio broadcast signals that are available to the digital radio broadcast receiver based on a location of the digital radio broadcast receiver.

8 - 30 . (canceled)

31 . A computer-implemented method for rendering content at a digital radio broadcast receiver system, the method comprising:
receiving a digital radio broadcast signal via digital radio broadcast transmission, the digital radio broadcast signal comprising data in a specified format for rendering content at the digital radio broadcast receiver; processing the digital radio broadcast signal to determine whether the data from the digital radio broadcast transmission contains a data error; transmitting a first notification to a computing system, the notification being effective to cause the processing of duplicate data to be transmitted via other wireless communication other than the digital radio broadcast transmission for rendering the content, the duplicate data permitting the content to be rendered without the data error, receiving the duplicate data at the digital radio broadcast receiver without the error via the other wireless communication based on the first notification, wherein the duplicate data comprises the data in the specified format of the digital radio broadcast signal transmitted by the digital radio broadcast transmitter system; and selecting the duplicate data received via the other wireless communication without the error for rendering at the receiver instead of selecting the data received by digital radio broadcast transmission that contains the data error so as to provide corrected data, and processing the corrected data at the digital radio broadcast receiver to provide an uninterrupted rendering of the content.

32 . The computer-implemented method of claim 31 comprising:
monitoring the digital radio broadcast signal received at the digital radio broadcast receiver while rendering the content based on the duplicate data received via the other wireless communication;
making a determination that a quality of the digital radio broadcast signal is sufficient to render content at the digital radio broadcast receiver; and
resuming rendering of content based on data received via digital radio broadcast transmission instead of data received via the other wireless transmission based on the determination.

33 . The computer-implemented method of claim 31 , wherein the duplicate data comprises a portion of a streaming content transfer.

34 . The computer-implemented method of claim 33 , wherein the streaming content transfer comprises a bit stream of unmodulated HD Radio Layer 2 data, the bit stream of unmodulated HD Radio Layer 2 data representing a plurality of digitally-encoded contents and control information formatted according to an HD Radio protocol.

35 . The computer-implemented method of claim 34 , wherein the bit stream of unmodulated HD Radio Layer 2 data is generated by a channel multiplexing layer of the digital radio broadcast transmitter that transmits the digital radio broadcast signal.

36 . The computer-implemented method of claim 31 comprising:
determining that the digital radio broadcast signal is not available to the digital radio broadcast receiver;
transmitting a second notification to the computing system based on the determination that the digital radio broadcast signal is not available to the digital radio broadcast receiver, the second notification effective to cause a streaming content transfer that comprises a bit stream of unmodulated HD Radio Layer 2 data, the HD Radio Layer 2 data comprising same data that is included in the digital radio broadcast signal;
receiving the streaming content transfer at the digital radio broadcast receiver via the other wireless communication based on the second notification;
processing the streaming content transfer at the digital radio broadcast receiver to recover digitally-encoded contents included in the HD Radio Layer 2 data; and
generating an output at the digital radio broadcast receiver b
