- Abstract
- The present invention relates to an inter-layer prediction method of an image including a plurality of layers and a method of transmitting a bitstream, each layer having at least one sub-layer. The inter-layer prediction method includes: decoding, from a bitstream, indicator information indicating whether there is maximum temporal sub-layer information; decoding information indicating an inter-layer reference relationship; decoding the maximum time sub-layer information from the bitstream based on the indicator information; deriving a maximum time identifier based on the maximum time sub-layerinformation; deriving a reference picture to be used for inter-layer prediction of the current picture of the second layer from the first layer based on the maximum temporal identifier; and performing inter-layer prediction of the current picture based on the reference picture, in which a picture of a first layer having a time identifier greater than the maximum time identifier is not used for inter-layer prediction of a current picture of a second layer, and when it is determined that the first layer is used as a direct reference layer of the second layer based on the information indicatingthe inter-layer reference relationship, the step of decoding the maximum time sub-layer information is executed.
