Embodiment Construction

[0061] figure 1 A simplified block diagram of a communication system (100) according to an embodiment of the disclosure is shown. A communication system (100) includes a plurality of terminal devices that can communicate with each other via, for example, a network (150). By way of example, a communication system (100) includes a first pair of end devices (110) and (120) interconnected by a network (150). exist figure 1 In an embodiment of the present invention, a first pair of terminal devices (110) and (120) perform unidirectional data transfer. For example, a terminal device (110) may encode video data (eg, a stream of video pictures captured by the terminal device (110)) for transmission to another terminal device (120) over the network (150). The encoded video data is transmitted in one or more encoded video streams. The terminal device (120) may receive encoded video data from the network (150), decode the encoded video data to restore the video data, and display vide...

Abstract

A method of video decoding for a decoder is provided. In the method, prediction information of a current block in a current picture is decoded from a coded video bitstream, where the prediction information is indicative of an inter prediction mode. Whether a filtering process is applied on the current block is determined, wherein the filtering process adjusts inter prediction samples of the current block based on neighboring reconstructed samples of the current block. A primary transform is thus performed for a transform block according to a pre-defined primary transform type based on that the filtering process is determined to be applied on the current block, where the transform block is partitioned from the current block.
