Abstract: A process comprises transmitting, by a first device and through a first communication channel, a message comprising an identifier of the first channel, a first encrypted authentication value and at least one encrypted data value, the first authentication value being associated with the first device, receiving, by a second device, the message, decrypting, by a first circuit of the second device, the first encrypted authentication value, applying, by the first circuit of the second device, at least one non-invertible operation on the first decrypted authentication value, resulting in a verification value, comparing, by the first circuit of the second device, the verification value with the identifier of the first channel, and processing the at least one encrypted data value based on the comparison.

Abstract: The present invention provides an improved method and device for generating a depth map (112) by extracting three-dimensional depth information from the movement vectors of an encoded video bit stream (102) to display two-dimensional video sequences onto three-dimensional displays. In particular, the invention performs depth extraction (110) by means of a post-processing of the movement vectors of the inter-coded macroblocks, which have been already encoded in the video bit stream, thereby significantly reducing the heavy processing requirements associated with conventional motion estimation techniques.

Abstract: A series (20) of original instructions for a single processor is translated into implementing instructions for executions distributed over a plurality of processors (12,16) of different type. The series (20) of original instructions is split into successive sections (22a-c,24a,b) assigned to respective ones of the processors (12,16). Operand transfer instructions are added to the sections (22a-c,24a,b) to support data dependencies between the sections (22a-c,24a,b). The assignment includes selecting a location of a boundary in the series of original instructions between successive ones of the sections (22a-c,24a,b) so as to substantially minimize an aggregate of the execution cost factors of the original instructions as implemented and including costs for the operand transfer instructions. Preferably, the locations of the boundaries are determined from a search among different boundaries positions.

Abstract: The present invention relates to a decoding apparatus and method for decoding compressed video data having a plurality of video frames with a plurality of blocks, wherein the video frames are split in a first predetermined direction into at least two stripes whose width does not exceed a hardware prediction line size. Then, coefficient prediction is performed on one of the at least two stripes to provide a predictor in a second predetermined direction for at least one other of the at least two stripes, the second predetermined direction being perpendicular to the first predetermined direction. Additionally, fake blocks are generated to be inserted into the at least one other of said at least two stripes in order to initialize prediction in the second predetermined direction. Thereby, hardware accelerators with fixed processing width can be used in a more flexible manner.

Abstract: A device and method for processing binary program files includes transferring a binary program file in the form of binary data packets over a communication network between a transmission device of a server platform and a reception device of a target platform. The reception device reorders the packets suitable for forming reordered-packet groups. A processor successively analyzes the reordered-packet groups so as to identify portions of code and processes the analyzed packets as soon as a portion of code has been identified.

Abstract: The present invention relates to method of processing binary program files, the method comprising a step of transferring a binary program file (11) in the form of binary data packets over a communication network (13) between a transmission device (12) of a server platform (10) and a reception device (14) of a target platform (18), a step of reordering the packets suitable for forming reordered-packet groups, and a processing step which is suitable for successively analyzing the reordered-packet groups so as to identify portions of code. The downloading of the binary program file, on the one hand, and the processing of the binary program file, on the other hand, are carried out according to a pipeline principle, which consequently makes it possible to process said binary program files more rapidly.
