LOW-COMPLEXITY ENHANCMENT VIDEO CODING USING TILE-LEVEL QUANTIZATION PARAMETERS

Title:

LOW-COMPLEXITY ENHANCMENT VIDEO CODING USING TILE-LEVEL QUANTIZATION PARAMETERS

Document Type and Number:

WIPO Patent Application WO/2024/065464

Kind Code:

A1

Abstract:

This disclosure describes systems, methods, and devices related to decoding low-complexity enhancement video coding (LCEVC) video data. A device may receive a bitstream including a first layer and enhancement layers; decode a video frame of the first layer of the bitstream using a base decoder; up-sample the decoded video frame; decode the video frame of a first enhancement layer using tile-level quantization parameters; generate a first combined intermediate video frame using the up-sampled video frame and the decoded video data of the first enhancement layer; up-sample the first combined intermediate video frame; decode encoded video data of a second enhancement layer; generate a second combined intermediate video frame using the decoded video data of the second enhancement layer and a selected reference frame; and generate a combined output video frame using the first combined intermediate video frame and the second combined intermediate video frame.
