发明名称 Method and apparatus for transmitting and downloading setup information
摘要 Multiple channel maps are embedded in a television transmission and the appropriate channel map (68) corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map (68) is accompanied by a channel map identifier (66) which identifies the source of the television transmission and geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map (68) having a channel map identifier (66) corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.
