ABSTRACT:
Basic transfer units (BTUs) of compressed video data of video images are selectively encrypted in accordance with an encryption policy to degrade the video images to at least a virtually useless state, if the selectively encrypted compressed video images were to be rendered without decryption. As a result, degradation that approximates the level provided by the total encryption approach is achieved, but requiring only a fraction of the processor cycle cost required by the total encryption approach, to decrypt and render the video images.
