Samsung filed a suit in the U.S. District Court of Delaware against Polaroid Corp. and Westinghouse Digital Electronics LLC for infringement of patents essential to the ATSC standard. The patents listed in the suit include, “Ghost cancellation reference signal with Bessel chirps and PN sequences and TV receiver using such signal” and “Method and apparatus for displaying information in a digital TV receiver.”
These licenses are now included in the ATSC Patent Portfolio License available through MPEG LA. MPEG LA collects a royalty of $5 for each ATSC receiver product for the patent holders. Zenith Electronics, another participant in the ATSC patent portfolio, is also suing Polaroid and Westinghouse for patent infringement in the U.S. District Court for the Eastern District of Texas.
