Method and apparatus for providing and receiving broadcaster information |
摘要 |
A method and apparatus identifies a tuned frequency or other information about a broadcaster or an interactive information system application using a description of the broadcaster or application, allowing an interactive information system to be easily controlled without requiring an information provider to identify a tuned frequency or other information. An information provider broadcasts broadcaster information to a reception component, and the reception component may identify the desired tuned frequency or other information using this broadcaster information. This allows interactive information system applications to locate a desired frequency or other information without requiring knowledge of information specific to each geographic or other boundary.
