1. A method performed by a video encoding apparatus for encoding a current layer, the method comprising:
determining a block-scan scheme for the current layer, the block-scan scheme including a location of a start block for blocks in the current layer and a scan order, wherein the scan order is one of a clockwise spiral scan order or a counterclockwise spiral scan order;
encoding a current block of the blocks using at least one encoded neighboring block of the current block based on the block-scan scheme;
determining at least one reference sample line for the current block;
determining at least one line buffer for storing the at least one reference sample line; and
storing information on the at least one reference sample line in the at least one line buffer.
