Abstract
The paper proposes a video scrambling technique that allows an unauthorized user to have an arbitrarily degraded view of a program, yet it is totally transparent to MPEG-2 encoding. Video components are block-coded using a mix of linear transformations of pixel values. The parameter data is embedded in the scrambled video. The proposed technique is applicable to any digital broadcast scheme that is based on MPEG-2 compression, including DVB-S/C/T and ATSC
