Abstract
A video decoder decodes a first indication () indicating whether transform coefficients of a first transform coefficient block () corresponding to a first color component are encoded into a data stream. The decoder also decodes a second indication () indicating whether transform coefficients of a second transform coefficient block () corresponding to a second color component are encoded into the data stream using context-adaptive entropy decoding with a context selected based on the first indication for the first transform coefficient block (). The decoder further derives a block () of the picture by, separately for the first color component and the second color component, a reverse transformation of the first transform coefficient block (and the second transform block (, respectively.
