Abstract
The present invention relates to video encoding and decoding method and apparatus, and a video encoding method according to the present invention comprises the steps of: entropy-encoding quantized transform information; and transmitting the entropy-encoded information as a bitstream, wherein the bitstream includes information indicating pieces of information to be parallel decoded in byte units.

1-20. (canceled)
A video encoding method, performed by an encoding apparatus, comprising:
- deriving entry point information specifying an entry point of a substream for a picture;
- encoding the entry point information to generate a bitstream;
- and
- outputting the generated bitstream,
- wherein the entry point information include 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 when the number of the offset syntax elements is larger than 0, wherein the offset syntax element represents an entry point offset 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 for 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 entry point information is configured in the slice header.
A video decoding method, performed by a decoding apparatus, comprising:
- obtaining entry point information specifying an entry point of a substream for a picture from a bitstream;
- and
- reconstructing the picture based on the entry point information,
- wherein the entry point information include 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 when the number of the offset syntax elements is larger than 0, wherein the offset syntax element represents an entry point offset 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 entry point information is configured in the slice header.
A non-transitory computer readable storage medium storing encoded information causing a video decoding apparatus to perform operations comprising:
- obtaining entry point information specifying an entry point of a substream for a picture from the encoded information;
- and reconstructing the picture based on the entry point information, wherein the entry point information include 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 when the number of the offset syntax elements is larger than 0, wherein the offset syntax element represents an entry point offset 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 entry point information is configured in the slice header.
