Abstract
An image decoding method according to the present disclosure presents indication information related to whether deblocking parameters for a deblocking filtering procedure exist in a picture header or a slice header.
Claims3
An image decoding method performed by a decoding apparatus, the method comprising:
- receiving a bitstream, wherein the bitstream includes specific information specifying in which one of a picture header or a slice header information related to a tool for a current block is present, and prediction information;
- obtaining, from one of the picture header or the slice header, the information related to the tool for the current block based on the specific information;
- generating a prediction sample for the current block based on prediction information;
- reconstructing a current picture based on the prediction sample and the information related to the tool for the current block;
- and
- wherein the specific information is included in a high level syntax including a Picture Parameter Set (PPS).

An image encoding method performed by an encoding apparatus, the method comprising:
- generating a prediction sample for a current block;
- reconstructing a current picture based on the prediction sample and a tool for the current block;
- generating a prediction information and information related to the tool for the current block;
- generating a specific information specifying in which one of a picture header or a slice header the information related to the tool for a current block is present;
- and
- encoding image information including the prediction information and the specific information,
- wherein the specific information is included in a high level syntax including a Picture Parameter Set (PPS).

A non-transitory computer readable digital storage medium storing a bitstream generated by a method, the method comprising:
- generating a prediction sample for a current block;
- reconstructing a current picture based on the prediction sample and a tool for the current block;
- generating a prediction information and information related to the tool for the current block;
- generating a specific information specifying in which one of a picture header or a slice header the information related to the tool for a current block is present;
- and
- encoding image information including the prediction information and the specific information to output the bitstream,
- wherein the specific information is included in a high level syntax including a Picture Parameter Set (PPS).
