Embodiment Construction

[0037] I. Encoders and decoders for video encoding and decoding

[0038] figure 2 is a simplified block diagram of a communication system (200) according to embodiments disclosed herein. A communication system (200) includes a plurality of terminal devices that can communicate with each other via, for example, a network (250). For example, a communication system (200) includes a first terminal device (210) and a second terminal device (220) interconnected by a network (250). exist figure 2 In an embodiment of the present invention, the first terminal device (210) and the second terminal device (220) perform unidirectional data transmission. For example, the first terminal device (210) may encode video data (such as a video image stream captured by the terminal device (210)) for transmission to the second terminal device (220) via the network (250). The encoded video data is transmitted in one or more encoded video streams. The second terminal device (220) may receive enco...

Abstract

This paper describes a video encoding and decoding method and device. A consolidated shared region may be received, the consolidated shared region comprising a plurality of coded blocks. Constructs a list of shared merge candidates for merging shared regions. The merged shared region is decoded based on the shared merge candidate list. Processing at least one coded block using inter-frame coding in the combined shared area, while not updating a history-based motion vector prediction (HMVP) table using motion information of the at least one inter-frame coded block.
