Abstract
Disclosed are a method and an apparatus for video decoding that support a plurality of layers. The method for video decoding includes acquiring information indicating whether tile information exists and acquiring the tile information based on the information indicating whether tile information exists.
Claims9
A method for video decoding supporting a plurality of layers, the method comprising:
- acquiring information indicating whether tile information exists;
- and
- acquiring the tile information based on the information indicating whether tile information exists,
- wherein the tile information is information representing whether locations of tiles existing in a picture of a current layer collocate with locations of tiles existing in a picture of a reference layer referred to by the current layer.
A method for video decoding supporting a plurality of layers, the method comprising:
- acquiring information indicating whether chroma format information and bit-depth information exist;
- and
- acquiring the chroma format information and the bit-depth information based on the information indicating whether the chroma format information and the bit-depth information exist.
An apparatus for video decoding supporting a plurality of layers, the apparatus comprising:
- an entropy-decoding unit configured to acquire information indicating whether tile information exists and acquire the tile information based on the information indicating whether tile information exists,
- wherein the tile information is information representing whether locations of tiles existing in a picture of a current layer collocate with locations of tiles existing in a picture of a reference layer referred to by the current layer.
An apparatus for video decoding supporting a plurality of layers, the apparatus comprising:
- an entropy-decoding unit configured to acquire information indicating whether chroma format information and bit-depth information exist and acquire the chroma format information and the bit-depth information based on the information indicating whether the chroma format information and the bit-depth information exist.
