Title: Improved video bitstream coding
Inventor: KRIT PANUSOPONE
IPC: H04N19/593
Filed: 2017-12-27
Abstract: Encoding or decoding video data, where planar mode intra prediction of a current coding block 702 involves the derivation of a bottom-right neighbouring pixel value, and calculating a second array of neighbouring pixels along the lower side 730 and right side of the current coding block from the intensity value of the bottom-right neighbouring pixel and pixels in a first array of neighbouring pixels along the upper side 716 and left side 714 of the current coding block. A first predictor and (different) second predictor for a pixel of the current block are each calculated by interpolating between an intensity value of a pixel in the first array and a pixel in the second array. In embodiments the first predictor 724 is calculated by interpolating between respective pixels in the row above the current block (in the first array) and the row along the lower side of the current block (in the second array) and the second predictor is interpolated from respective pixels in the column on the left of the current block (first array) and in the column on the right side (in the second array). A prediction block is derived from the two predictors, e.g. by averaging them.

Title: Technique for collecting state information of an apparatus
Inventor: JOHN MICHAEL HORLEY
IPC: G06F11/34
Filed: 2020-05-14
Abstract: A technique is providing for collecting state information of an apparatus. The apparatus has a processing pipeline for executing a sequence of instructions, and interesting instruction designation circuitry for identifying at least one of the instructions in the sequence as being an interesting instruction. Each interesting instruction is an instruction for which given state information of the apparatus associated with execution of that interesting instruction is to be collected. The interesting instruction designation circuitry is arranged, for each identified interesting instruction, to apply defined selection criteria to determine a further instruction later in the sequence of instructions than the interesting instruction, and to mark that further instruction as having a synchronous exception associated therewith. The processing pipeline is responsive to the further instruction reaching a given stage of the processing pipeline and being marked as having the synchronous exception associated therewith, to trigger the synchronous exception instead of executing a further instruction, which causes the processing pipeline to execute a given exception handling routine in order to collect the given state information.

Title: Hydrocarbon exploration method
Inventor: SVEND ØSTMO
IPC: G01V1/30
Filed: 2021-04-30
Abstract: A method of exploring for hydrocarbons in a region comprises obtaining seismic data for the region at two or more different times (e.g. dates) e.g. four-dimensional seismic data. The data is compared to determine a time shift between the seismic data measured at the two or more different times. Based on the comparison an assessment is made whether there is likely to be hydrocarbons in the region, and whether the hydrocarbons are likely to be oil or gas. If the time shift is greater than a predetermined value e.g. around 0.5 to 1.5 ms then it is assessed that the hydrocarbons are likely to be oil. Determining whether there is likely to be hydrocarbons may also be based on whether there is an amplitude change.
