METHOD OF ENCODING FLAGS IN LAYER USING INTER-LAYER CORRELATION, METHOD AND APPARATUS FOR DECODING CODED FLAGS

摘要

A method and apparatus for efficiently encoding diverse flags being used in a multilayer-based scalable video codec, based on an inter-layer correlation. The encoding method includes judging whether flags of a current layer included in a specified unit area are all equal to flags of a base layer, setting a specified prediction flag according to the result of judgment, and if it is judged that the flags of the current layer are equal to the flags of the base layer, skipping the flags of the current layer and inserting the flags of the base layer and the prediction flag into a bitstream.
