The present disclosure relates to an apparatus and a method for image processing each of which enables reduction of a coding efficiency to be suppressed. In the case where primary transformation as transformation processing for a predictive residue as a difference between an image and a predictive image of the image and secondary transformation as transformation processing for a primary transformation coefficient obtained by subjecting the predictive residue to the primary transformation are caused to be skipped, a switch also causes bandwidth limitation for a secondary transformation coefficient obtained by subjecting the primary transformation coefficient to the secondary transformation to be skipped. The present disclosure, for example, can be applied to an image processing apparatus, an image coding apparatus, an image decoding apparatus or the like.

In at least one embodiment, a method and apparatus for encoding/decoding a video is based on a CABAC coding of bins where a high-level constraint on the maximum usage of regular CABAC coding of bins is enforced. In other words, a budget of regular coded bins is allocated over a picture area that is larger than a coding group, thus covering a plurality of coding groups, and which is determined from an average allowed number of regular bins per unit of area.

Methods, systems, and devices for coding or decoding video wherein the picture partition mode is based on block size are described. An example method for video processing includes using a dimension of a virtual pipeline data unit (VPDU) used for a conversion between a video comprising one or more video regions comprising one or more video blocks and a bitstream representation of the video to perform a determination of whether a ternary-tree (TT) or a binary tree (BT) partitioning of a video block of the one or more video blocks is enabled, and performing, based on the determination, the conversion, wherein the dimension is equal to VSize in luma samples, wherein dimensions of the video block are CtbSizeY in luma samples, wherein VSize=min(M, CtbSizeY), and wherein M is a positive integer.

A method of decoding an enhanced video stream composed of base layer video access units and enhancement layer video access units, each access unit comprising a plurality of syntax structures, includes passing the syntax structures of the base layer access units to a base layer buffer, passing syntax structures of the enhancement layer access units to an enhancement layer buffer, outputting the syntax structures passed to the base layer buffer in a predetermined sequence, outputting the syntax structures passed to the enhancement layer buffer in a predetermined sequence, and recombining the sequences of syntax structures output by the base layer buffer and the enhancement layer buffer respectively to form a complete enhanced access unit, composed of base layer syntax structures and enhancement layer syntax structures in a predetermined sequence.

The present disclosure is directed to a method and system for increasing virtual machine (VM) density on a server system through adaptive rendering by dynamically shifting video rendering tasks to a client computing device. In one embodiment, a processor in a server manages virtual machines in the server by controlling a number of VMs and an amount of system resources allocated to the VMs. The number of VMs and the amount of resources allocated to the VMs are controlled by shifting video rendering from at least one of the VMs to a client device, and increasing the number of the VMs in the server after the shifting.

A method, computer program, and computer system is provided for coding video data. Video data including a current picture and one or more other pictures is received. A first flag corresponding to whether the current picture is referenced by the one or more other pictures in a decoding order is checked. A second flag corresponding to whether the current picture is output; is checked. The video data is decoded based on values corresponding to the first flag and the second flag.
