Abstract: Apparatus and method for protecting firmware and other types of control data used in a processor-based device, such as but not limited to a solid-state drive (SSD). In some embodiments, the firmware is stored in a firmware store as a plurality of program instructions in a first sequence. The program instructions are loaded to a local memory in a different, second sequence. In some cases, a random number is generated and the second sequence is selected using the random number. A translation table may be generated and used by a programmable processor to locate the various program instructions in the second sequence. In other cases, instructions with calls and other references to other instruction lines are modified based on the order in the local memory. Other forms of control data may also be generated and stored to the local memory in a random order and interspersed with the firmware.

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.

Abstract: A content receiving apparatus including a receiver receiving first contents from a broadcasting station, a temporary memory unit temporarily storing first contents-related information related to the first contents, a memory storing the first contents and storing, based on an input recording request, the first contents-related information; and the memory storing a plurality of second contents and a plurality of second contents-related information received from a server, the second contents-related information being related to the first contents, and displayable.
