This disclosure describes example techniques that a video coder (eg, video encoder or
video decoder) may utilize to determine a block vector for a chroma block where the partition …

There is provided a method comprising encoding an uncompressed constituent frame into a
first encoded picture, said encoding also resulting into a reconstructed first picture and said …

Various innovations facilitate the use of intra-picture prediction modes such as palette
prediction mode, intra block copy mode, intra line copy mode and intra string copy mode by …

Innovations in intra block copy (" BC”) prediction mode facilitate intra BC prediction that is
more effective in terms of rate-distortion performance and/or computational effi ciency of …

Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In
some example implementations, bitstream syntax, semantics of syntax elements and many …

Innovations in the area of prediction of block vector (“BV”) values improve encoding or
decoding of blocks using intra block copy (“BC”) prediction. For example, some of the …

Innovations in encoder-side options for intra block copy (“BC”) prediction mode facilitate
intra BC prediction that is more effective in terms of rate-distortion performance and/or …

When encoding/decoding a current block of a current picture using intra block copy (“BC”)
prediction, the location of a reference block is constrained so that it can be entirely within an …

A video coder may determine a search region for coding a current block of video data using
Intra Block Copy (Intra BC). In some examples, the video coder determines a central point for …

Approaches to robust encoding and decoding of escape-coded pixels in a palette mode are
described. For example, sample values of escape-coded pixels in palette mode are …
