    Abstract: Coding method complexity types are assigned to video for combinations of coding decision levels associated with a sequence of pictures, a group of pictures, pictures, a scene, a region of the scene or picture, a block or macroblock. Multiple coding units are encoded as a function of complexity and determined from the coding decision levels. A first coding decision level is associated with determining a first complexity and a first coding method type for the sequence of pictures. A second coding decision level is associated with determining a second complexity and a second coding method type for the pictures or scene. The picture or sequence includes the coding units. A third coding decision level is associated with determining a third complexity and a third coding method type for the coding units.

    Abstract: Controlling a feature of an encoding process for regions of an image pattern representing more than one image when the regions include an amount of disparity in the represented images that would result in cross-contamination between the represented images if encoded with the feature. The control may be, for example, any of, turning the encoding feature off, using the encoding feature less often than when encoding an image pattern representing a single image, negatively biasing the encoding feature, and enabling the encoding feature for regions determined to have zero or near zero disparity and disabling the feature for all other regions. The represented images comprise, for example, any of a stereoscopic view, multiple stereoscopic views, multiple views of a same scene, and multiple unrelated views.

    Abstract: Techniques and systems are disclosed that relate to overlapped block disparity estimation and compensation. Some methods for compensation of images with overlapped block disparity compensation (OBDC) involve determining if OBDC is enabled in a video bit stream, and determining if OBDC is enabled for one or more macroblocks that neighbor a first macroblock within the video bit stream. The one or more neighboring macroblocks can be transform coded. If OBDC is enabled in the video bit stream and for the one or more neighboring macroblocks, the methods involve performing prediction for a region of the first macroblock that has an edge adjacent with the one or more neighboring macroblocks. OBDC can be causally applied. The methods can involve sharing or copying one or more disparity compensation parameters or modes amongst one or more views or layers. Various types of prediction can be used with causally-applied OBDC features and techniques.

    Abstract: 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.
