    Abstract: Techniques for coding and deriving (e.g., determining) one or more coded-block-flags associated with video content are described herein. A coded-block-flag of a last node may be determined when coded-block-flags of preceding nodes are determined to be a particular value and when a predetermined condition is satisfied. In some instances, the predetermined condition may be satisfied when log2(size of current transform unit) is less than log2(size of maximum transform unit) or log2(size of current coding unit) is less than or equal to log2(size of maximum transform unit)+1. The preceding nodes may be nodes that precede the last node on a particular level in a residual tree.

    Abstract: Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In some example implementations, bitstream syntax, semantics of syntax elements and many coding/decoding processes for inter prediction mode are reused or slightly modified to enable intra BC prediction for blocks of a frame. For example, to provide intra BC prediction for a current block of a current picture, a motion compensation process applies a motion vector that indicates a displacement within the current picture, with the current picture being used as a reference picture for the motion compensation process. With this unification of syntax, semantics and coding/decoding processes, various coding/decoding tools designed for inter prediction mode, such as advanced motion vector prediction, merge mode and skip mode, can also be applied when intra BC prediction is used, which simplifies implementation of intra BC prediction.

    Abstract: A method and a system for transmitting data are provided. In a source apparatus, original data is divided into a plurality of source segments, a similarity calculation is performed for each of the source segments to obtain a similarity set, and the similarity set is transmitted to a target apparatus. In the target apparatus, whether a target segment corresponding to the source segment exists in the target apparatus is determined according to the similarity set to obtain a comparison result, and the comparison result is transmitted to the source apparatus. In the source apparatus, after the original data is dehydrated according to the comparison result to obtain dehydration data, the dehydration data is transmitted to the target apparatus. In the target apparatus, the dehydration data is rehydrated to the original data.

    Abstract: Acquisition of magnetic resonance (MR) data in a predetermined three-dimensional volume segment of an examination subject with an MR apparatus proceeds by the volume segment being excited with an RF excitation pulse, and repeated, temporally sequential implementation of the following in order to respectively read out an echo train: Switch a refocusing pulse. Switch a first phase coding gradient in a first direction and a second phase coding gradient in a second direction. Switch an additional magnetic field gradient for spatial coding in a third direction which is perpendicular to the first direction and the second direction, wherein the MR data of a k-space line are read out while the additional magnetic field gradient is switched. Every k-space line corresponds to a line of k-space that corresponds to the volume segment. At least one k-space line is read out repeatedly in a middle segment of k-space.
