Title: Discrete dither
Inventor: PETER GRAHAM CRAVEN
IPC: H03M7/30
Filed: 2018-12-18
Abstract: Dither techniques are used to reduce the noise penalty (signal variance) in certain circumstances whilst still removing noise modulation. One method reduces the wordwidth of audio by one bit by pseudo randomly choosing one of two consecutive output values where one is chosen a quarter of the time (with probability 25%). If the least-significant bit is to be truncated, the prior art dithers symmetrically and either introduces noise modulation (if a rectangular distribution is used for dithering) or raises the level of noise (if a triangular distribution is used). Instead, dithering 12 asymmetrically (with a bias or offset 12), removes noise modulation and reduces noise compared with prior art, albeit with a small DC offset to the signal that is immaterial to audio. Another method relates to burying one bit of data in a pair of signal samples by choosing between two 2-tuples that both convey that bit (Fig. 5).

Title: Controller for a vehicle internal combustion engine
Inventor: NICK BROCKLEY
IPC: F02P5/04
Filed: 2019-05-29
Abstract: Disclosed is a controller 14 for a vehicle internal combustion engine 12 operable in a catalyst heating mode. The controller receives in input including a drive torque request, e.g. a driver-demanded drive torque, and a measurement of actual mass airflow into the engine. The controller determines a required engine ignition efficiency value based on the received torque request and actual air mass, and defines an actual engine ignition efficiency value to be the minimum of the required engine ignition efficiency value and a threshold maximum engine ignition efficiency value. The controller determines an ignition timing to be applied to the engine based on the determined actual engine ignition efficiency value, and controls the engine to operate in accordance with the applied engine ignition timing when the engine is operating in the catalyst heating mode. An associated method of controlling an internal combustion engine is also disclosed. The invention ensures that when a high torque demand is present during a catalyst heating event the engine is not so efficient that it cannot provide the required heat to the catalyst.

Abstract: An image processor (401, Fig. 4) comprises a plurality of stencil processors 300, each stencil processor having respective arrays of execution lanes 305, two-dimensional (2D) shift registers 306, the latter including local individual register space for the dedicated execution lanes. The processor is configured to operate a CNN layer having a plurality of coefficient sets (702, Fig.7), performing a number of operations. Different groups of coefficients are loaded into the different stencil processors, respectively. An identical plane of image data, extracted from a three-dimensional (3D) block (701, Fig. 7) is entered into each shift register array. Each stencil processor performs a 2D convolution of the same image data with its specific coefficient values by sequentially concurrently multiplying, within the execution threads, respective pixel and coefficient values generating a matrix of partial products (Fig. 11 a). These partial products are summed in parallel with respective sums of partial products stored in the shift register for separate stencils defining sub-regions of pixel values, which are aligned for 2D convolution by shifting data (Figs. 5a-5k). Stencil processors may be linked with a dedicated sheet generator and/or to a line buffer unit. A related method and computer program product are also disclosed.

Title: Data coding and decoding
Inventor: GUILLAUME LAROCHE
IPC: H04N19/52
Filed: 2022-04-11
Abstract: Processing predictors, e.g. for the encoding or decoding of video, images, point cloud, or audio data. A list of predictors is obtained, having at least two predictors, such as motion vector predictor candidates in video coding. It is determined whether to modify the list of predictors based on a criterion using a first cost related to a first predictor in the list and a second cost related to a second predictor in the list. The list of predictors is modified based on the determination. The criterion is based on a threshold value. Preferably, the decision relates to whether to reorder predictors or candidates in the list, or whether to remove or delete predictors or candidates from the list. The criterion may involve comparing the difference or absolute difference of the costs of the predictors to the threshold. A predictor may be deleted or moved to the end of the list if the costs of the predictor and its predecessor in the list are similar (below the threshold). The cost may be a template matching cost. The threshold may be based on information in a bitstream, or a quantisation parameter (QP), picture order count (POC) or temporal ID of a frame.

IPC: H04L65/403
Filed: 2022-08-05
Abstract: A method for rendering digital content on first and second digital content renderers. The second renderer receives a communication indicating properties of a first content viewing area of the first renderer, and state data indicative of a configuration (e.g. co-ordinates, size, shape, state, movement) of an object (e.g. a video, text, streaming media) in the first area. Based on the received properties of the first area and first state data, the second renderer renders a second content viewing area 301 with a portion that contains an interactive representation of the first area 302, the portion including an indication of the object 312, 313. The second renderer receives a user interaction 320 within the interactive representation that changes the configuration of (e.g. relocates, resizes, edits content within) the object and generates second state data based on the change. The second renderer sends a communication to the first renderer indicating the second state data that causes the first renderer to modify the object rendered in the first area to conform with the change. The method may be used for presentation sessions or multimedia calls between a customer/guest and a host/agent.
