1. A method for video encoding, comprising:
dividing a video block into a plurality of coding units;
grouping two or more of the plurality of coding units into at least one group of coding units wherein the grouping comprises associating an indication with each of the plurality of coding units, the indication indicating whether a shared coding information is to be used in the encoding of the respective coding unit; and
encoding the plurality of coding units, wherein:
for a coding unit that is associated with an indication that the shared coding information is to be used, the encoding is performed based on the shared coding information, and
for a coding unit that is associated with an indication that the shared coding information is not to be used, the encoding is performed based on coding information determined for the coding unit.
