A method and device for coding screen content into a bitstream by selecting a color palette
table for a coding unit (CU) of screen content, creating a color index map having indices for …

(57) ABSTRACT A video coding device may encode a video signal using intra-block copy
prediction. A first picture prediction unit of a first picture may be identified. A second picture …

In an example, a method of processing video data includes coding at least one of data that
indicates a maximum palette size of a palette of color values for coding a block of video data …

An apparatus is configured to perform a method for screen content encoding. The method
includes deriving a palette table and a color index map based on a coding unit (CU). The …

In an example, a method of coding video data includes determining, for a pixel associated
with a palette index that relates a value of the pixel to a color value in a palette of colors …

In an example, a method of processing video data includes determining a value of a block-
level syntax element that indicates, for all samples of a block of video data, whether at least …

The geometric pose of a patch of watermark data is estimated based on the position of a
similar, but non-identical, patch of information within a data structure. The information in the …

Methods of palette coding to reduce the required coding process are disclosed. According to
one method, smaller blocks are derived from a large block. The histogram of the large block …

In one example aspect, a method of video processing includes performing a conversion
between a current block of a video and a bitstream of the video using a palette mode in …

In one example aspect, a method of video processing includes performing a conversion
