Abstract
Disclosed are an image encoding/decoding method and device supporting a plurality of layers. The image decoding method supporting the plurality of layers comprises the steps of; receiving a bitstream comprising the plurality of layers; and decoding the bitstream so as to acquire maximum number information about sublayers with respect to each of the plurality of layers.
Claims8
A method for picture decoding supporting layers, the method comprising:
- receiving a bitstream comprising the layers;
- acquiring information on a maximum number of sub-layers for each of the layers by decoding the bitstream;
- acquiring a residual block of a current block by decoding the bitstream;
- and
- generating a reconstructed block of the current block using the residual block,
- wherein the information on the maximum number of sub-layers is included in video parameter set extension information and signaled, and
- wherein a video parameter set comprises information on a maximum number of sub-layers.
A method for picture encoding supporting layers, the method comprising:
- acquiring information on a maximum number of sub-layers for each of the layers;
- acquiring a reconstructed block of a current block;
- acquiring a residual block of the current block using the reconstructed block;
- and
- transmitting a bitstream comprising the information on the maximum number of sub-layers by encoding the information on the maximum number of sub-layers for each of the layers, and comprising information on the residual block by encoding the residual block,
- wherein the information on the maximum number of sub-layers is included in video parameter set extension information and signaled, and
- wherein a video parameter set comprises information on a maximum number of sub-layers.
A non-transitory computer-readable storage medium storing a bitstream, wherein the bitstream is generated by a method for picture encoding supporting layers, the method comprising:
- acquiring information on a maximum number of sub-layers for each of the layers;
- acquiring a reconstructed block of a current block;
- acquiring a residual block of the current block using the reconstructed block;
- and
- transmitting a bitstream comprising the information on the maximum number of sub-layers by encoding the information on the maximum number of sub-layers for each of the layers, and comprising information on the residual block by encoding the residual block,
- wherein the information on the maximum number of sub-layers is included in video parameter set extension information and signaled, and
- wherein a video parameter set comprises information on a maximum number of sub-layers.
