Comcast and Cablevision's quest to keep the HD feeds of the networks they own off of satellite and telco services was again dealt a loss Friday when the U.S. Court of Appeals for the District of Columbia upheld new FCC rules requiring them to share. Neither found that pleasing, with Comcast citing the continued exclusivity of NFL Sunday Ticket and NASCAR Hot Pass to DirecTV, while Cablevision whined about its latest spat with ABC. This might not be the end of things however, as the court voted the FCC could later rescind the rule if it decides it "is no longer timely," and it will likely play a part in the ongoing discussions over Comcast's proposed purchase of NBC.
