1. A video encoding method, performed by an encoding apparatus, comprising:
reconstructing a picture;
deblocking filtering on the picture;
deriving entry point information specifying an entry point for decoding at least one substream for the picture;
encoding the entry point information to generate a bitstream; and
outputting the generated bitstream,
wherein the entry point information includes a number syntax element representing a number of offset syntax elements in a slice header,
wherein the entry point information includes an offset syntax element representing the entry point of the substream when the number of the offset syntax elements is larger than 0,
wherein the offset syntax element represents a number of bytes between two entry points,
wherein the entry point information includes a length syntax element when the number of the offset syntax elements is larger than 0, wherein the length syntax element represents a bits length of the offset syntax element,
wherein a value of the length syntax element plus one corresponds to the bits length of the offset syntax element,
wherein a value of the number syntax element corresponds to the number of offset syntax elements in the slice header, and
wherein the offset syntax element is signaled based on whether there is more than one tile present in the picture and whether rows of coding tree units in the picture are parallel decoded.
