Abstract
An intra prediction method and apparatus. The intra prediction method of intra predicting a macroblock divided into a plurality of blocks includes intra predicting the plurality of blocks in a predetermined scanning order. One or more block among the plurality of blocks are intra predicted independently of their respective, immediate preceding block that is intra predicted immediately before the one or more blocks are intra predicted and are intra predicted in parallel with their respective, immediate preceding blocks.
Claims18
An intra prediction method of intra predicting a macroblock divided into a plurality of blocks, the intra prediction method comprising:
- intra predicting the plurality of blocks in a predetermined scanning order,
- wherein at least one block among the plurality of blocks is intra predicted independently of an immediately preceding block of the at least one block that is intra predicted immediately before the at least one block and is intra predicted in parallel with the immediately preceding block.
An intra prediction method of intra predicting a macroblock in units of a predetermined block, the intra prediction method comprising:
- requesting pixel information of adjacent blocks required for intra prediction of the predetermined block in a predetermined scanning order;
- receiving the requested pixel information of adjacent blocks;
- and
- performing intra prediction in the predetermined scanning order,
- wherein the predetermined scanning order enables at least one block to be intra predicted in parallel with an immediately preceding block of the least one block.
An intra prediction apparatus for intra predicting a macroblock divided into a plurality of blocks, the intra prediction apparatus comprising:
- an adjacent pixel information providing unit providing pixel information of adjacent blocks used in intra prediction;
- and
- a prediction unit requesting the pixel information of adjacent blocks from the adjacent pixel information providing unit and performing intra prediction using the received pixel information of adjacent blocks,
- wherein the prediction unit performs the intra prediction in a predetermined scanning order that enables at least one block to be intra predicted in parallel with an immediately preceding block of the at least one block.
A program product embodied on a computer-readable medium storing a program including program instructions executed by a computer for executing an intra prediction method of intra predicting a macroblock in units of a predetermined block, the intra prediction method comprising:
- requesting pixel information of adjacent blocks required for intra prediction of the predetermined block in a predetermined scanning order;
- receiving the requested pixel information of adjacent blocks;
- and
- performing intra prediction in the predetermined scanning order,
- wherein the predetermined scanning order enables at least one block to be intra predicted in parallel with an immediately preceding block of the least one block.
