Embodiment Construction

[0024] The following descriptions are preferred embodiments of the present invention. The following examples are only used to illustrate the technical characteristics of the present invention, and are not intended to limit the present invention. The scope of protection of the present invention should be defined by the claims.

[0025] According to existing video encoders using the QTBT structure, the encoder will evaluate the performance of each candidate block segmentation. For example, the rate-distortion values ​​of all block partitions related to a CTU or CU will be evaluated, and the encoder will select the block partition that achieves the best performance. During performance evaluation, the blocks resulting from the target block split are coded using a set of coding parameters to determine performance, such as rate-distortion values.

[0026] Due to the flexibility of QTBT splitting, different block splits can produce the same target block. exist Figures 4A-4C , an...

Abstract

A method and apparatus for video coding using block partition are disclosed. According to the present invention, if a target block in the current image unit is generated from a first block partition as well as a second block partition, the coding information reuse is applied. According to the coding information reuse, a first set of coding parameters is determined for the target block generated from the first block partition. A second set of coding parameters is determined for the target block generated from the second block partition by reusing at least one encoder coding decision by the target block generated from the second block partition. When different types of blocks are partitioned to generate the same target block, there is no need to independently determine different code parameter sets, thereby reducing the calculation complexity.

Description

technical field [0001] Embodiments disclosed herein relate to block partitioning for coding and / or prediction processing in video coding. In particular, the present invention relates to an encoding method such that a target block produced by another block division reuses encoding information of the same target block produced by one block division. Background technique [0002] The High Efficiency Video Coding (HEVC) standard is established by the Video Coding Experts Group (VCEG) of ITU-T and the Moving Picture Experts Group (MPEG) of ISO / IEC. Developed under the Joint Video Project, this partnership is specifically called the Joint Collaborative Team on Video Coding (JCT-VC) partnership. in HEVC. Divide a slice into multiple coding tree units (CTU). In the main configuration file, the minimum and maximum size of the CTU is specified by syntax elements in the sequence parameter set (SPS). The allowed CTU sizes can be 8x8, 16x16, 32x32, or 64x64. For each slice, the CTUs...
