Abstract: The techniques of this disclosure are generally related to parallel coding of video units that reside along rows or columns of blocks in largest coding units. For example, the techniques include removing intra-prediction dependencies between two video units in different rows or columns to allow for parallel coding of rows or columns of the video units.

Abstract: An apparatus configured to filter video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit stores video information comprising at least two adjacent video blocks, each video block comprising a plurality of video samples, and each video sample having a bit depth. The processor determines a filtered video sample based at least in part on a video sample and an adjustment value. The processor determines the adjustment value at least in part from an input with a limited bit depth. The input is determined from a set of one or more video samples, and its bit depth is limited such that it is less than the bit depth of the one or more video samples.

Abstract: A method includes executing, at a processor, a dedicated arithmetic encoding instruction. The dedicated arithmetic encoding instruction accepts a plurality of inputs including a first range, a first offset, and a first state and produces one or more outputs based on the plurality of inputs. The method also includes storing a second state, realigning the first range to produce a second range, and realigning the first offset to produce a second offset based on the one or more outputs of the dedicated arithmetic encoding instruction.

Abstract: Described herein are methods, systems, and apparatus to process video images to remove jitteriness due to hand shake. In one aspect, a camera is configured to capture raw video composed of a series of successive image frames of a scene of interest. A processor is configured to receive the image frames, estimate a global camera motion from successive frames, stabilize the camera motion by establishing an upper bound and a lower bound of the global camera motion and smoothing the curve of camera motion between the upper and lower bounds, and upsample the resulting stabilized video frames to produce a smooth video.
