Digital radio broadcast receiver, broadcasting methods and methods for tagging content of interest
View Patent ↗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.

The method of claim 7 , wherein the first program data comprises one or more Unique File Identifier (UFID) frames including information identifying the first item and another item of interest and including one or more Uniform Resource Locator (URL) addresses for obtaining information about the first item and the another item.
11. The method of claim 2 , wherein the predetermined time period is 10 seconds.
12. 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.
13. A digital radio broadcast receiver, comprising:
