1. A method for generating a media file, the method comprising:
configuring first flag information for a target layer in an Output Layer Set (OLS), wherein the first flag information represents whether information on a maximum number of temporal sublayers for inter-layer prediction is present;
configuring second flag information on whether the target layer is an output layer;
configuring, based on the first flag information and the second flag information, the information on the maximum number of the temporal sublayers; and
configuring a media file including an operating points information sample group,
wherein the operating points information sample group includes the first flag information and the second flag information, and
wherein the information on the maximum number of the temporal sublayers is configured in the operating points information sample group based on both i) the first flag information being equal to 1 and ii) the second flag information being equal to 0.
