Title: Media processing systems
Inventor: DAMIAN PIOTR MODRZYK
IPC: H04N21/84
Filed: 2018-05-14
Abstract: When a producer processing unit, such as a video decoder, of a media processing system is producing 600 a data output for use by a consumer processing unit, such as a display processor, the producer processing unit also generates 602 metadata for the data output that it is producing and provides 603 that metadata for use by the consumer processing unit. The consumer processing unit then uses 605, 606 the metadata provided by the producer processing unit when processing 607 the data output to which the metadata relates. Metadata may represent absolute characteristic(s) of data or data output (frame) changes, and may be used for image enhancement, scene change detection, scene-aware colour management, scaling or tone mapping. For data output as a YUV frame, metadata can comprise average YUV values and a low resolution luminance layer derived from the full resolution YUV frame. Other metadata parameters may comprise noise level information, or gradients and/or edge sharpness in data output regions. The system and associated method facilitates provision of metadata to assist consumer unit processing, while reducing or avoiding the need for consumer or user units (clients) themselves to generate metadata.

IPC: G08B7/06
Filed: 2018-06-11
Abstract: A plurality of emitters may be provided for indicating an escape route to at least one emergency exit of a building. The escape route is determined based on environmental data such as building layout and location of an emergency situation. The emitters may generate an audible sound, such as a voice indicating a distance/direction to an exit. Each emitter may generate a different audible sound, such that a person can determine a direction in which to travel to exit the building. The sound generated from different emitters may differ in pitch or frequency of modulation or may be sequenced in the direction of travel. The plurality of emitter may produce visual cues indicating the direction in which to travel to exit the building. The visual clues may be different colours which may also be sequenced in the direction of travel. The alarm system may comprise a central server which may determine the route to the exit. The exit route may be re-determined if one of the emitters becomes inactive or if the emergency situation is on the route to an exit.

Title: Method of hologram calculation
Inventor: NEIL COLLINGS
IPC: G03H1/16
Filed: 2018-08-23
Abstract: Calculating a fully complex hologram by (i) receiving an input image comprising a plurality of data values representing amplitude; (ii) assigning a random phase value to each of the data values to form a complex dataset; (iii) performing an inverse Fourier transform of the complex dataset; (iv) constraining each complex value of the transformed complex dataset to one of a plurality of allowable complex values, each comprising an amplitude modulation value and a phase modulation value, to form a hologram. The phase modulation values of allowable complex data values substantially span at least 3p/2 and at least one of the allowable complex data values is substantially zero. Preferably, the allowable complex values lie on a characteristic line in the complex plane, spiraling around the origin in a first closed loop with a tail section extending towards the origin. Values X_1 inside a region 450 may be quantized to zero GL8, and values X_2 outside may be quantized to a point GL1-GL7 on the unit circle. The combined amplitude and phase SLM modulator is tuned to attain combined modulation values on the characteristic line when the voltage is varied. The hologram generation algorithm is based on the Gerchberg-Saxton iterative algorithm.

Title: Calculating structural differences from binary differences in publish subscribe system
Inventor: PHILIP ALAN GEORGE ASTON
IPC: H04L12/58
Filed: 2017-03-27
Abstract: A method for more efficient structural parsing of binary representations of text based objects within a data distribution system. Clients subscribe to a topic maintained by the data distribution system server that publishers can publish to. Clients receive an original binary representation of a text based object describing the state of the topic to which the client is subscribed. In response to the state of the topic changing at the data distribution system server, clients receive a binary delta representing the change of the state of the topic. Based on the received binary representation and the binary delta, clients calculate an updated binary representation of the text based object. Using the original binary representation, the updated binary representation, and the binary delta, the client generates a structural delta representing the structural differences between data structures of the original text based object and data structures of the updated text based object.

Title: Generating a triangle mesh for an image represented by curves
Inventor: VINEET BATRA
IPC: G06T17/20
Filed: 2018-10-16
Abstract: Generating image graphics comprises obtaining an image (244) represented by curves (e.g. splines, Bezier curves), rasterising the image (246), generating outlines of portions of the image (248), and determining an edge list indicating a plurality of polylines representing the outline(s) (250). A mesh is generated (252) including a respective triangle mesh for each outline based on the edge list. The curves are bound (254) to the mesh by representing samples of the curves with the (e.g. barycentric) coordinates of the samples, and then binding the curve samples to the mesh with respect to a respective (i.e. specific) triangle in the mesh e.g. by determining which triangle encloses or is nearest the coordinate. The triangle mesh is generated based on the edge list rather than by directly sampling the curves and using the samples as vertices of triangles. Thus, the mesh is generated with a number of triangles independent from a number of curves. Hence, once a mesh is deformed (256) (e.g. using handles), locations of the samples are determined from the (e.g. barycentric) coordinates and triangles in the deformed mesh, and used to reconstruct (258) the curves of the deformed image.
