摘要： This disclosure describes techniques for encoding digital video data using interpolation filters and offsets. An encoder may be configured to select interpolation filters for sub-pixel precision motion estimation based on historical interpolation results obtained for previously encoded video units, such as frames or slices. The encoder also may be configured to compute and assign offsets to the sub-pixel positions after interpolation based on differences between a reference unit and the unit to be coded. The computation and assignment of offsets may be performed before motion estimation. Motion estimation may be refined so that the motion search considers sub-pixel positions to which offsets have been previously added and evaluates sub-pixel positions that have a non-zero offset. In some cases, interpolation filter selection, offset computation, and/or refined motion estimation for a given unit may be performed in a single encoding pass.

摘要： This disclosure describes techniques associated with filtering of video data in a video encoding and/or decoding process. In accordance with this disclosure, filtering is applied at an encoder, and filter information is encoded in the bitstream to identify the filtering that was applied at the encoder. Different types of filtering may be applied based on an activity metric determined for the video data. Moreover, in accordance with this disclosure, the manner in which the filter information is encoded into the bitstream may be dependent on the activity metric. In particular, for a first range of the activity metric, one or more filters are encoded directly, and for a second range of the activity metric, one or more filters are predictively encoded.

In one example, a method of encoding a video block includes interpolating a first block of predictive values based on a first reference video unit within a first list of reference data, and a second block of predictive values based on a second reference video unit within a second list of reference data, calculating, for sub-integer pixel positions, a first offset value based on the first block and the current video block, and a second offset value based on the first offset value and the second block, determining a final block of offset values based on the first block of predictive values, the second block of predictive values, the first offset values, and the second offset values, and encoding the current video block based on the final block of offset values.

摘要： Systems and methods to process motion vectors of video data are disclosed. According to an embodiment, an intra-block in a video frame of the video data is identified. At least a first set and a second set of inter-blocks that neighbor the identified intra-block are identified, where each inter-block in a set of inter-blocks has a motion vector associated therewith. Data of the first and second set of inter-blocks is evaluated to determine an error associated with each of the first and second sets. A motion vector associated with motion vectors of the inter-blocks of the set with the least error is determined. The determined motion vector may be associated with the identified intra-block.
