Abstract:
1. A method of coding video data, the method comprising: determining, for a first plurality of coding units, that at least one adjacent coding unit in a second plurality of coding units is unavailable for use in intra-prediction coding of a portion of one coding unit in the first plurality of coding units; determining padding values for pixels located in the second plurality of coding units determined as unavailable for use in intra-prediction coding; coding the first plurality of coding units in a tile of the video data; and coding the second plurality of coding units in the tile of the video data after at least one coding unit in the first plurality of coding units is coded, such that coding the second plurality of coding units occurs substantially in parallel with coding the first plurality of coding units, wherein coding the first plurality and the second plurality of coding units includes intra-prediction coding, and wherein the intra-prediction coding uses the determined padding values for pixels located in the second plurality of coding units determined as unavailable for use in intra-prediction coding.
