Abstract
A television method and receiver are configured to receive a television broadcast signal that includes multimedia data files including hypertext data. The multimedia data files relate to a television program guide and the hypertext data includes address information that designates a linked multimedia data file. Once extracted and stored, a processor interprets the multimedia data files and generates a display signal including the television program guide and link portions based on the hypertext data. The processor is able to recognize and address information of each link portion that is pointed to by way of a user interface. The processor then retrieves the linked multimedia data file corresponding to the recognized address information and interprets the retrieved linked multimedia data file so as to generate the display signal.
