Embodiment Construction

[0042] figure 1 is a simplified block diagram of a communication system (100) according to embodiments disclosed herein. The communication system (100) includes a plurality of terminal devices, which can communicate with each other, eg, via a network (150). For example, the communication system (100) includes a terminal device (110) and a terminal device (120) interconnected by a network (150). exist figure 1In the embodiment of the present invention, the terminal device (110) and the terminal device (120) perform one-way data transmission. For example, the end device (110) may encode video data (eg, a stream of video pictures captured by the end device (110)) for transmission over the network (150) to another end device (120). 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 video pictures accordin...

Abstract

Various embodiments of the present application provide video decoding methods and devices, computer equipment, and storage media. In some embodiments, a video decoding method includes: decoding prediction information of a first block in a current picture from an encoded video bitstream, the prediction information indicating that the first block is determined according to a motion vector predictor An inter prediction mode for the first motion vector; responsive to the inter prediction mode, creating a candidate list of candidate motion vector predictors, the candidate list excluding a plurality of second blocks that were used in the motion vector derivation One or more operations need to be performed in the process to determine the second motion vector of the second block; determine the first motion vector of the first block based on the candidate list of candidate motion vector predictors; reconstruct the first motion vector from the first motion vector of the first block piece.
