Digital video recorder (DVR) filtering of on-screen graphics
摘要:
A method and digital video recorder (DVR) mechanism that (1) filters out added graphical content that a user/viewer does not wish to view during live feed and/or playback of a recorded program, (2) adds graphical content to a live feed and/or recorded program, and (3) enables manipulation of graphical content for display with live feed and/or recorded programs. The logic/functionality of the DVR is enhanced to include features/functionality that allows the viewer to filter/add/manipulate certain graphical content (and its associated audio) from/to/within the program being displayed on the display screen. The received broadcast content contains identifying information about the graphical content, separate from the identifying information of the program content that that would allow the DVR functionality to identify and filter out certain (or all) aspects of the graphics. Different types of graphical content have different identifiers, so that the viewer is able to selectively filter out or add or manipulate one type of graphical content independent of the other(s).
