Title:

ADAPTIVE RESOLUTION CODING BASED ON MACHINE LEARNING MODEL

Document Type and Number:

WIPO Patent Application WO/2021/072694

Kind Code:

A1

Abstract:

At least one video frame and a corresponding bit rate of the at least one video frame of a video may be determined. The video may be a streaming video or a subset of a stored video. The at least one video frame and the corresponding bit rate into may be inputted into a machine learning model to obtain a recommended resolution. The at least one video frame and one or more other video frames associated with the at least one video frame may then be resized or resampled (e.g., downsampled) according to the recommended resolution. After resizing, the at least one video frame and the one or more other video frames may be encoded to obtain an encoded video according to a target bit rate.
