Abstract

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.

Claims

1. A method of generating a digital radio broadcast signal formatted to facilitate specifying content of interest using a digital radio broadcast receiver, the method comprising:

arranging first audio content and second audio content for broadcast via a digital radio broadcast signal;

structuring first program data associated with the first audio content and second program data associated with the second audio content,

the first program data comprising a first Unique File Identifier (UFID) frame comprising a first type code specifying a type of a first item associated with the first audio content, a first ID code identifying the first item, and a first Uniform Resource Locator (URL) address for obtaining information about the first item, the first type code being associated with one of an audio product, a merchandise product, and a subscription service,

the second program data comprising a second Unique File Identifier (UFID) frame comprising a second type code specifying a type of a second item associated with the second audio content, a second ID code identifying the second item, and a second Uniform Resource Locator (URL) address for obtaining information about the second item; and

generating a digital radio broadcast signal comprising the first and second audio content and the first and second program data for transmission via digital radio broadcast.

2. The method of claim 1, wherein the first UFID frame comprises a type code and an ID code for another item of interest.

3. The method of claim 1, wherein the first UFID frame comprises multiple ID codes identifying multiple different formats in which the first item is available.

4. The method of claim 1, wherein the first program data comprises multiple UFID frames, each of which includes a Uniform Resource Locator (URL) address for obtaining information about the first item of interest, such that information can be obtained about the first item from multiple sources.

5. The method of claim 1, wherein the first program data comprises another UFID frame, the another UFID frame including a type code and an ID code for another item of interest and including a Uniform Resource Locator (URL) address for obtaining information about the another item of interest.

6. The method of claim 1, wherein the first program data comprises one or more type codes selected from the group consisting of “

APC”

indicating that the first program data include one or more audio product codes, “

MPC”

indicating that the first program data include one or more merchandise product codes, and “

SPC”

indicating that the first program data include one or more codes for subscription services.

7. The method of claim 1, comprising transmitting the digital radio broadcast signal.

8. The method of claim 1, wherein the UFID frame includes data identifying the first item and another item of interest, and a Uniform Resource Locator (URL) address for obtaining information about the first item and the another item of interest.

9. A digital radio broadcast system for generating broadcast data formatted to facilitate specifying content of interest using a digital radio broadcast receiver, comprising:

a processing system; and

a memory coupled to the processing system,

wherein the processing system is configure to;

arrange first audio content and second audio content for broadcast via a digital radio broadcast signal;

structure first program data associated with the first audio content and second program data associated with the second audio content,

the first program data comprising a first Unique File Identifier (UFID) frame comprising a first type code specifying a type of a first item associated with the first audio content, a first ID code identifying the first item, and a first Uniform Resource Locator (URL) address for obtaining information about the first item, the first type code being associated with one of an audio product, a merchandise product, and a subscription service,

the second program data comprising a second Unique File Identifier (UFID) frame comprising a second type code specifying a type of a second item associated with the second audio content, a second ID code identifying the second item, and a second Uniform Resource Locator (URL) address for obtaining information about the second item;

generate a digital radio broadcast signal comprising the first and second audio content and the first and second program data for transmission via digital radio broadcast.

10. The digital radio broadcast system of claim 9, wherein the first UFID frame comprises a type code and an ID code for another item of interest.

11. The digital radio broadcast system of claim 9, wherein the first UFID frame comprises multiple ID codes identifying multiple different formats in which the first item is available.

12. The digital radio broadcast system of claim 9, wherein the first program data comprises multiple UFID frames, each of which includes a Uniform Resource Locator (URL) address for obtaining information about the first item of interest, such that information can be obtained about the first item from multiple sources.

13. The digital radio broadcast system of claim 9, wherein the first program data comprises another UFID frame, the another UFID frame including a type code and an ID code for another item of interest and including a Uniform Resource Locator (URL) address for obtaining information about the another item of interest.

14. The digital radio broadcast system of claim 9, wherein the first program data comprises one or more type codes selected from the group consisting of “

APC”

indicating that the first program data include one or more audio product codes, “

MPC”

indicating that the first program data include one or more merchandise product codes, and “

SPC”

indicating that the first program data include one or more codes for subscription services.

15. The digital radio broadcast system of claim 9, wherein the UFID frame includes data identifying the first item and another item of interest, and a Uniform Resource Locator (URL) address for obtaining information about the first item and the another item of interest.
