Problems solved by technology

In other cases, the MV prediction itself may be lossy, e.g. lossy due to rounding errors when computing predictors from several surrounding MVs.

Embodiment Construction

[0041] I. Video encoding encoder and decoder

[0042] figure 2 It is a simplified block diagram of a communication system (200) according to an embodiment disclosed herein. The communication system (200) includes a plurality of terminal devices that can be communicated with each other by, for example, a network (250). For example, the communication system (200) includes a first terminal device (210) and a second terminal device (220) interconnected through the network (250). exist figure 2 In the embodiment, the first terminal device (210) and the second terminal device (220) perform one-way data transmission. For example, the first terminal device (210) can encode video data (e.g., a video image stream acquired by the terminal device (210) to transmit to the second end device (220) over the network (250). The encoded video data is transmitted in one or more encoded video codes. The second terminal device (220) can receive the encoded video data from the network (250), decoding the...

Abstract

Aspects of the disclosure provide a method and an apparatus for video coding. In some examples, an apparatus includes processing circuitry that divides a current block into a plurality of sub-blocks, derives a plurality of pieces of sub-block motion information for the plurality of sub-blocks, generates predicted sub-block samples for the sub-blocks according to the pieces of sub-block motion information, and generates a predicted block for the current block according to a combination of the predicted sub-block samples. The processing circuitry also selects a piece of the sub-block motion information from the pieces of sub-block motion information as representative motion information for the current block, and stores the representative motion information in a history-based motion vector prediction (HMVP) buffer.

Description

[0001] Related documents [0002] The present application claims priority to the topic of the "HMVP buffer update method" submitted on March 6, 2019, and the topic submitted on 3 March 3, 2020 is "video codec method and device" The priority of the US application 16 / 808, 213, which is incorporated herein by reference. Technical field [0003] The present application examples mainly involve video codec technology. Background technique [0004] The background description provided herein is to present the background of the present application. The work of the inventors, the work described in the background section and the content within the scope of the embodiments of the present specification, may not be as suited or suggested as it is not conducive to this Existing technology for applications. [0005] Video coding and decoding can be performed using inter-image predictions with motion compensation. Uncompressed digital video can include a series of images, each image has a certain ...
