ABSTRACT:
A method for operating a video processing system by receiving initial copyright information from a first source, storing the initial copyright information, receiving updated copyright information from a second source, and updating the stored copyright information in response to the updated copyright information. For example in one embodiment of the present invention, the initial copyright information for a program is received from an electronic program guide and updated copyright information is received along with the selected program. The video processing system may be programmed to operate in a first operating mode in response to the initial copyright information and the operating mode of the video processing system may be switched to a second operating mode in response to the updated copyright information.
