Claim 55:
56. A non-transitory digital storage medium having a computer program stored thereon which, when executed by a processor, causes an apparatus to perform a method for block-based encoding of a picture into a data stream, the picture comprising a plurality of blocks to be encoded, the method comprising:
determining an intra-coding mode for a current block of the plurality of blocks;
partitioning, along a partition dimension, the current block into a number of partitions, wherein the number of partitions is greater than 2;
sequentially processing each partition of the current block according to a predetermined partition order along the partition dimension by,
for a current partition of the current block,
deriving a predictor for the current partition of the current block using the intra-coding mode for the current block based on one or more already encoded samples neighboring the current partition;
determining a prediction residual for the current partition, wherein:
if the current partition is not the last partition in the current block, based on the predetermined partition order, encoding a coded partition flag into the data stream and if the coded partition flag is one encoding transform coefficients of the current partition into the data stream, and if the coded partition flag is zero, skipping encoding transform coefficients for the current partition; and
if the current partition is the last partition in the current block based on the predetermined partition order, and if each coded partition flag for each previously reconstructed partition in the current block is zero, skipping encoding the coded partition flag for the current partition and encoding the transform coefficients of the current partition into the data stream.
