ABSTRACT:
A method and apparatus are disclosed for providing High-Bandwidth Digital Content Protection during a channel change process. The method and apparatus include detection of High-Bandwidth Digital Content Protection capability on a receiver during an interface event. High-Bandwidth Digital Content Protection authentication is delayed for a predetermined time period to allow the channel change process to stabilize. The invention reduces a performance penalty associated with the channel change process.
