  • REFERENCE PICTURE LIST MANAGEMENT SYNTAX FOR MULTIPLE VIEW VIDEO CODING
    Publication number: 20190182506
    Abstract: A picture reference list ordering process is defined for a multiview coder for coding moving pictures, where the picture list has the coding order of reference pictures used to code a picture specified in relationship to whether a picture to be coded is associated with a view. The ordering of the picture list will therefore change the coding order of the reference pictures in the picture reference list depending on the temporal relationships the reference pictures have with the picture to be coded and views associated with the reference picture.

  • CHROMA RESHAPING OF HDR VIDEO SIGNALS
    Publication number: 20190124367
    Abstract: Methods for the chroma reshaping of high-dynamic range (HDR) signals are presented. For each input pixel, a first scaler is generated based on the pixel luminance and a luma-based chroma reshaping (LCR) function. A second scaler is generated based on a saturation-based chroma reshaping (SCR) function and the saturation value of the pixel. A cascaded scaler is generated by multiplying the first scaler with the second scaler. Reshaped chroma values are generated by multiplying the input chroma values with the cascaded scaler. The characteristics of preferred LCR and SCR functions are discussed. Inverse decoding methods based on chroma-reshaping metadata that define the LCR and SCR functions are also described.
