Abstract: Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.

Abstract: According to a method for Adaptive Loop Filter (ALF) processing of reconstructed video, multiple indicators are signaled in slice at an encoder side or parsed at a decoder side, where the multiple indicators are Adaptive Parameter Set (APS) indices associated with temporal ALF filter sets for the ALF processing. A current indicator is determined from the multiple indicators, where the current indicator is used to select a current ALF filter set. Filtered-reconstructed pixels are derived for the current block by applying the current ALF filter to the current block. In another method, if the ALF processing applied at a target sample requires an outside sample on other side of a target virtual boundary from the target sample, the outside sample is replaced by a padded sample.

According to one method, a current permitted band inside the current picture for the current block is identified. A target IBC candidate is selected, where a target block vector of the target IBC candidate points from the current block to a target reference block in the current picture.

In another method, a syntax for a target MVD (Motion Vector Difference) is decoded without sign information or with reduced sign information of the target MVD.

Abstract: Video processing methods and apparatuses in a video encoding or decoding system for processing a video picture partitioned into blocks with one or more partition constraints. The video encoding or decoding system receives input data of a current block and checks whether a predefined splitting type is allowed to partition the current block according to first and second constraints. The first constraint restricts each sub-block partitioned from the current block to be completely contained in one pipeline unit, and the second constraint restricts each sub-block partitioned from the current block to contain one or more complete pipeline units. The pipeline units are non-overlapping units in the video picture designed for pipeline processing. The current block is not partitioned by the predefined splitting type if any sub-block partitioned by the predefined splitting type violates both the first and second constraints. The system encodes or decodes the current block.
