Abstract

Systems, apparatuses, and methods are described for enhancing picture reconstruction in video coding. Bitstream information, such as original bit depth and range indicators, may be used to adjust reconstruction parameters. Compact representations of range differences may be signaled to enable efficient decoding. By adapting clipping ranges for reconstructed samples, the system may improve visual fidelity and reduce artifacts, even when internal processing operates at a different bit depth than the source. These techniques may support flexible configurations and maintain compression efficiency across diverse video formats.
