    摘要: Adaptive motion information cost estimation is achieved in processing video information. A transmission cost is estimated that is associated with encoding a motion vector difference (mvd) in motion vectors that describe a motion characteristic of the video information. The mvd is encoded based on minimizing a rate estimation mismatch associated with the motion vectors. The encoding step includes computing a bit count associated with the mvd using CABAC. A value is indexed that corresponds to the cost from one or more entries in the lookup table. The cost relates to context or content characteristics associated with the video information. The lookup table is adaptively updated based on a change in the contextual information or content characteristics. The value is dynamically adjustable based on the change.

    摘要: Video coding schemes may include one or more filters to reduce coding artifacts and improve video quality. These filters may be applied to decode video data in a predetermined sequence. The output from one or more of these filters may be selected for different images, blocks, or sets of video data and then copied and/or routed to a display or a buffer storing reference data that is used to decode other video data in a data stream. Providing the ability to select which filter output is used for display and as a reference may result in better video quality for multiple types of video data. The filters that are selected for display and for reference may be different and may vary for different images, blocks, and data sets.
