Abstract
A video decoding method and device according to the present disclosure may receive a bitstream including an encoded video picture and reconstruct the encoded video picture included in the bitstream. Here, the bitstream may include a quality metric SEI message. The quality metric SEI message may include a quality metric definition flag indicating whether information defining the quality metrics is included in the quality metric SEI message, and quality metric number information indicating the number of quality metric entries included in the quality metric SEI message.
