主权项

1. A method executable by a television receiver to dynamically detect a web address in one or more frames of a video multimedia presentation, the method comprising:
receiving and decoding the video multimedia presentation by the television receiver; automatically extracting a first frame from the decoded video multimedia presentation, wherein the automatic extracting is initiated by the television receiver without input by the user; analyzing the first frame to identify a pattern of characters, wherein the pattern of characters comprises at least a portion of a web address associated with a website available on the Internet; if the pattern of characters is identified within the first frame, then obtaining the entire web address from the first frame, creating a selectable link that links to a website associated with the web address, and indicating the obtained web address within one or more frames of the video component; providing the first frame to a display device for display; bypassing analyzing a second frame in the video multimedia presentation, the second frame occurring later in time than the first frame; providing the second frame to the display device for display; analyzing a third frame to identify the pattern of characters, the third frame occurring later in time than the second frame; and providing the third frame to the display device for display.
