Method, medium, and system encoding and/or decoding an image

A system for encoding image data, comprising:

• an image reorganization unit to generate a plurality of image slices for each of three color components of 4:4:4 chroma format;
• and
• an encoding unit, implemented by at least one processing device, to separately encoding the three color components based on an encoding type information, each of the three color components including the plurality of image slices and to generate a bitstream including the separately encoded three color components and the encoding type information,
• wherein each of the plurality of image slices contains one of the three color components.

A method of decoding image data from a bitstream, comprising:

• checking an encoding type information included in the bitstream;
• and
• separately decoding three color components of 4:4:4 chroma format based on an encoding type information, each of the three color components including a plurality of encoded image slices included in the bitstream, with independency in decoding between the three color components,
• wherein each of the plurality of encoded image slices contains one of the three color components.
