METHOD AND APPARATUS FOR IMAGE DECODING

摘要

PURPOSE: An image decoding method and an apparatus thereof are provided to decode information about a reference picture set which is described in a slice header depending on a type of a slice, thereby removing unnecessary reference picture set information about an intra-slice. CONSTITUTION: A decoding apparatus parses header information about a current slice (S310). The decoding apparatus decodes the current slice without constructing a reference picture set about the current slice depending on a type of the current slice based on the parsed header information (S340). If the current slice is an intra-slice, the decoding apparatus does not constructs a reference picture set about the current slice. [Reference numerals] (S310) Constructing a reference picture set by slice header parsing; (S320) Marking restoration picture not existing in reference picture set as unused for reference; (S330) Perform bumping; (S340) Slice decoding; (S350) Marking decoded slice as used for reference when the slice is reference picture
