AI Technical Summary

Problems solved by technology

It can be seen that, in the transmission process in the above-mentioned palette mode, since the transmitted index will include the index of the main color and the skipping index, if there is no skipping pixel in the encoding unit block at all, keep This skipped index would add unnecessary overhead when transmitting each index of the CU block

Embodiment Construction

[0053] Figure 1A is an encoder according to an exemplary embodiment of the present disclosure.

[0054] Please refer to Figure 1A , the encoder 110 includes a flag setting module 112 , a palette table building module 114 , an index map building module 116 , an encoding module 118 , a storage circuit 130 and a processor circuit 140 .

[0055] In this exemplary embodiment, the storage circuit 130 is used to store various data, program codes, or images to be processed and processed. For example, the storage circuit 130 may be a storage medium such as a memory or a hard disk (Hard Disk Drive, HDD), but is not limited thereto. The processor circuit 140 is used for controlling the overall operation of the encoder 110 . For example, the processor circuit 140 may be a central processing unit (CPU), a micro-processor (micro-processor) or an embedded controller (embedded controller), which is not limited in the present disclosure. The processor circuit 140 is coupled to the storage ...

Abstract

An encoding method, a decoding method, an encoding and decoding system, an encoder and a decoder. The coding method includes in palette mode, when the color of each pixel of the coding unit block is represented by one or more main colors of the coding unit block, this flag will be set to the first state value, And when the color of at least one pixel among the pixels of the coding unit block is not represented by one or more main colors, the flag will be set as the second state value. The coding method further includes establishing a palette table corresponding to the coding unit block according to the state value of the flag and the one or more main colors.

Description

technical field [0001] The present disclosure relates to an encoding method and a decoding method applicable to a coding unit block having a plurality of pixels, as well as a codec system, an encoder, and a decoder using the method. Background technique [0002] With the evolution of science and technology, the analysis, specifications and size of video displays are getting higher and higher, and people's requirements for video picture quality and size are also rising. To meet this demand, VCEG (Video Coding Experts Group) under the International Telecommunication Union (ITU-T) and MPEG (Moving Picture Experts Group) under the International Organization for Standardization ISO / IEC jointly established Video Coding The joint working group JCT-VC (JointCollaborative Team on Video Coding) started the H.265 / HEVC (High Efficiency Video Coding) project, aiming to provide higher coding efficiency than the H.264 / AVC (Advanced Video Coding) video compression standard , especially hig...
