Title:
SYSTEM AND METHOD FOR CONTROLLING VIDEO CODING AT FRAME LEVEL
Document Type and Number:
WIPO Patent Application WO/2019/104635
Kind Code:
A1
Abstract:
System and method can control video coding. A video encoder can obtain a target rate to encode an image data unit such as an image frame, wherein the image data unit is to be encoded based on a rate control model with one or more model parameters. The video encoder can determine values of the one or more model parameters for the rate control model based on an encoding of one or more reference image data units using one or more reference coding parameters. Then, the video encoder can determine values of one or more coding parameters for encoding the image data unit, based on the rate control model with the one or more determined model parameters, and use the one or more determined coding parameters to encode the image data unit.
