1. A video decoding method, by a video decoding apparatus, comprising:
receiving a bitstream including a slice header and substreams for a current slice segment;
obtaining entry point information for the substreams from the slice header; and
reconstructing a picture by decoding the substreams based on the entry point information,
wherein the reconstructing the picture includes:
deriving prediction information on a block of a current substream;
deriving prediction samples for the block based on the prediction information;
generating reconstructed samples for the picture based on the prediction samples; and
performing deblocking filtering on the picture,
wherein the picture includes multiple largest coding units (LCUs),
wherein a number of the substreams is equal to a number of LCU rows in the current slice segment in the picture,
wherein the entry point information includes number information indicating a number of entry point offsets,
wherein the number of the substreams is derived based on the number information in the slice header,
wherein the substreams are substreams for wavefront parallel processing (WPP),
wherein the number of entry point offsets is signaled through the slice header, and
wherein the number of the substreams is derived based on the number of entry point offsets.
