Classification: CPC H | IPC H

Claim 3:
4. The method of claim 1, wherein the format rule further specifies that a tile column index is derived for each CTB column of the tile of the video picture, and wherein the tile column index for a ctbAddrX-th tile column, denoted as ctbToTileColIdx[ctbAddrX], is derived as follows:
tileX=0
for(ctbAddrX=0; ctbAddrX<=PicWidthInCtbsY; ctbAddrX++) {
if(ctbAddrX==tileColBd[tileX+1])
tileX++
ctbToTileColIdx[ctbAddrX]=tileX

},
wherein PicWidthInCtbsY represents a width of the video picture in units of CTBs, and
wherein tileColBd[i] represents a location of an i-th tile column boundary in units of CTBs.
