摘要： 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.

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： A value of one or more Lagrangian multipliers is adaptively estimate and update based, at least in part, on the video source statistics or dynamic programming. Methods, techniques, and systems involve determining a first Lagrangian multiplier with a video encoder, and updating a second Lagrangian multiplier with the first Lagrangian multiplier. The system can include a Lagrangian multiplier Estimation Module that estimates the Lagrangian multiplier, and a Lagrangian multiplier Update Module that updates the current Lagrangian multiplier using the estimated Lagrangian multiplier. The Online Lagrangian Multiplier Estimation Module may function with Rate Distortion Slope Estimation with Rate Distortion Optimized Mode Decision; Rate Distortion Slope Estimation with Local Approximation; Rate Distortion Slope Estimation with Local Information; or Rate Distortion Slope Estimation with Global Information. The Lagrangian Multiplier Update Module may function with Direct Update; Step Size Update; Sliding Window Update; or Periodical Update.

摘要： There is provided a compression method for handling local brightness variation in video. The compression method estimates the weights from previously encoded and reconstructed neighboring pixels of the current block in the source picture and their corresponding motion predicted (or collocated) pixels in the reference pictures. Since the information is available in both the encoder and decoder for deriving these weights, no additional bits are required to be transmitted.
