Abstract
A video processing system includes a video device that generates a request corresponding to video content. A conditional access module generates a video signal for transmission to the video device during a first time period, and terminates transmission of the video signal when the request is not authenticated during the first time period. In a further embodiment, the conditional access module generates a video signal for unscrambled transmission to the video device during a first time period, terminates the unscrambled transmission of the video signal at the expiration of the first time period, and continues with scrambled transmission of the video signal after the first time period.
