Abstract
There are described methods and apparatus for scrambling digital content, such as video or audio content, by dividing the digital content into blocks set out in an original arrangement, and reordering the blocks from the original arrangement to a scrambled arrangement. Additional manipulation transforms such as rotations and reflections may be applied to individual blocks. A subsequent compression step may then be carried out. Methods and apparatus for carrying out corresponding descrambling of digital content are also described.
