Abstract
Provided are methods and apparatuses for encoding and decoding video. The method of decoding video includes determining a type of an upper-layer data unit including a current coding unit in a hierarchical structure of a data unit; and obtaining, from a bitstream, intra-frame skip mode information of the current coding unit, according to the determined type of the upper-layer data unit, wherein, according to different types of the upper-layer data unit, the intra-frame skip mode information is expressed as code words having different lengths in the bitstream.
Claims15
A method of decoding video, the method comprising:
- determining a type of an upper-layer data unit comprising a current coding unit in a hierarchical structure of a data unit;
- and
- obtaining, from a bitstream, intra-frame skip mode information of the current coding unit, according to the determined type of the upper-layer data unit,
- wherein, according to different types of the upper-layer data unit, the intra-frame skip mode information is expressed as code words having different lengths in the bitstream.
A video decoding apparatus comprising:
- a data unit type determiner configured to determine a type of an upper-layer data unit comprising a current coding unit in a hierarchical structure of a data unit;
- and
- an information obtaining unit configured to obtain, from a bitstream, intra-frame skip mode information of the current coding unit, according to the determined type of the upper-layer data unit,
- wherein, according to different types of the upper-layer data unit, the intra-frame skip mode information is expressed as code words having different lengths in the bitstream.
A method of encoding video, the method comprising:
