Abstract: In one embodiment, a method for providing media content implemented on a broadcast headend includes defining at least one metablock of media content according to a number of media content data blocks, where the media content data blocks are ordered in accordance with associated serial numbers, reordering the media content data blocks in the at least one metablock of media content to generate reordered data blocks, obfuscating the associated serial numbers in the reordered data blocks, providing details of the reordering to a receiving device, and transmitting the reordered data blocks to a receiving device.
