摘要： In a method of video coding, in which a difference is formed between input picture values and picture prediction values and that difference is transforming with a DCT, the picture prediction is formed as: P=(1−c)Pc+CPo where Pc is a closed loop predictor which is restricted to prediction values capable of exact reconstruction in a downstream decoder and Po is a spatial predictor which is not restricted to prediction values capable of exact reconstruction. The factor can vary from zero to unity depending on a variety of parameters.

摘要： A setter for setting the teeth of a band saw blade. The setter has at least one up-set tool bit configured to increase the set of a blade tooth. The distance between the up-set tool bit and the blade tooth is adjustable by a first threaded member. The setter also has at least one down-set tool bit configured to decrease the set of the blade tooth. The distance between the down-set tool bit and the blade tooth is adjustable by a second threaded member. A mechanical linkage is configured to move the at least one up-set tool bit toward the blade tooth, and also configured to move the at least one down-set tool bit toward the blade tooth during a set operation. Wherein during the set operation, a clamping linkage clamps the blade within the setter, and the at least one up-set tool bit is driven toward the blade tooth of the clamped band saw blade by the mechanical linkage, and the at least one down-set tool bit is driven toward the opposing side of the blade tooth of the clamped band saw blade by the mechanical linkage. The distance between the at least one up-set tool bit and the blade tooth is adjusted via the first threaded member such that during the set operation, the up-set tool bit applies a first up-set displacement to the blade tooth. The distance between the at least one down-setting tool bit and the blade tooth is adjusted via the second threaded member such that during the set operation, the down-set tool bit applies a first down-set displacement to the blade tooth. The mechanical linkage of the setter comprising a follower arm and cam design.

摘要： In video coding, where differences between input picture values and picture prediction values are transformed in a block based transform, the differences are formed in a series of parallel steps. A first step conducted in parallel upon a first subset of pixels uses prediction values based wholly on previously processed blocks. This first subset can include anchor pixels which are not contiguous with any previously processed block. A second step conducted in parallel upon a second subset includes pixels which are predicted from pixels of the first subset.

摘要： An image encoder utilising a transformation operating between a spatial domain and a DCT or other transform domain, employs the steps of forming a prediction; subtracting the prediction to form a difference; and quantising the difference in a transform domain, where the prediction is formed in the transform domain and the transform domain prediction is weighted.
