Abstract: Methods of encapsulating a bitstream include generating reference information to enable image items identifying image portions of a bit stream to be referenced to corresponding description information. The resulting encapsulated file may also include information identifying a timed portion of the data stream corresponding to a video sequence. Description information may include spatial parameters, such as position and width and height of sub-parts of an overall image, and/or display parameters such as colour display, pixel aspect ratio, and clean aperture parameters.

Abstract: A method of encapsulating image data in a media file, the image data being related to a main image to be generated based on a plurality of sub-images, wherein the method comprises: obtaining the plurality of sub-images, each sub-image being provided in at least one version; generating descriptive metadata for describing the main image and the plurality of sub-images; encapsulating the plurality of sub-images and the descriptive metadata in the media file; wherein the method further comprises: generating a progressive information defining a set of consecutive progressive steps for generating a version of the main image, each progressive step being associated with a set of sub-images versions required to generate the version of the main image; and embedding the progressive information in the descriptive metadata.

Abstract: The present invention concerns a method of encoding video data comprising frames into a bitstream, frames being spatially divided into frame portions, the method comprising: encoding at least one frame portion into one or more first encoded units; wherein the method further comprises: signalling into said first encoded units, at least one frame portion identifier, a frame portion identifier identifying one encoded frame portion; and providing frame portion arrangement information comprising the frame portion identifier and spatial information about the frame portion.

Abstract: Tooling for manufacture of an apertured element made of a composite material includes first and second sole plates and tooling elements. Each sole plate is configured to be placed on either side of the apertured element to be manufactured. The tooling elements are placed between the first and second sole plates. The tooling elements include at least one core and peripheral bars. The core is configured to delimit a cell of the apertured element to be manufactured. The core is movable in translation along the first and second sole plates. The peripheral bars are placed on a periphery of the core and configured to delimit the apertured element to be manufactured. At least one peripheral bar is movable in translation along the first and second sole plates.

Abstract: A laser projection method and device for drape-molding a part on a mold includes encoders to determine the theoretical position of calibration patterns according to a displacement of the mold such that a laser projector is automatically recalibrated when the mold is repositioned during the drape-molding operation.

Abstract: The present disclosure provides a method for manufacturing a sound attenuation panel having a first cellular core structure and a second cellular core structure joined in a junction area (J). The method includes: a) a joining edge of the first cellular core structure is joined to a corresponding joining edge of the second cellular core structure, thereby forming the junction area; b) the first cellular core structure and the second cellular core structure are placed between an inner skin and an outer skin of the panel. In particular, the method further has a step prior to step a), in which one junction reinforcement is inserted between the joining edge of the first cellular core structure and the corresponding joining edge of the second cellular core structure in the junction area.

Abstract: A method for heating a composite material area to be repaired includes placing a primary heating pad on the area to be repaired, and placing one or more satellite heating pads on the periphery of the primary pad in a manner that the satellite heating pads are adjacent to the edges of the primary pad.

Abstract: The present disclosure relates to a method for repairing a portion of an acoustic panel for a nacelle of an aircraft turbojet engine. The panel includes an acoustic skin in which a plurality of acoustic holes are drilled, a solid skin, and a cellular acoustic structure. The cellular acoustic structure, being arranged between the acoustic skin and the solid skin, has a plurality of cells, each of which has one or more drainage openings arranged in one or more of the walls forming each cell. The method includes a step of: defining a part of the acoustic panel to be cut; forming a cutting area closed by the acoustic skin; injecting a resin through the acoustic holes; positioning a replacement cellular acoustic structure in the cutting area and on the acoustic skin; forming a solid replacement skin on the replacement cellular acoustic structure.
