发明名称 VERFAHREN UND VORRICHTUNG ZUR ÜBERTRAGUNG UND PROGRAMMLADUNG VON AUFBEREITUNGSINFORMATIONEN
摘要 Multiple channel maps are embedded in a television transmission and the appropriate channel corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a 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 having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.
