Introduction to H.264 Intra prediction H.264 FRExt uses several types of spatial predictions such as the 16 ´ 16, 8 ´ 8, 4 ´ 4 Green blocks, 16 ´ 16 Red block and 16 ´ 16 Blue block predictions. (...) The 16 ´ 16 block prediction makes use of four different prediction methods, viz. the vertical, horizontal, DC and planar modes. (...) Each prediction direction uses the previously-decoded block boundary pixels to predict the pixels in the 4 ´ 4 block.

Mode 0 is ‘DC-prediction’ (see below). The other modes represent directions of predictions as indicated below. 3.5.1 Mode 0: DC prediction Generally all pixels are predicted by (A+B+C+D+E+F+G+H)//8. (...) A block may therefore always be predicted in this mode. 3.5.2 Mode 1: This mode is used only if all A,B,C,D are inside the picture. a is predicted by: (A+B)/2 e is predicted by B b,i are predicted by (B+C)/2 f,m are predicted by C c,j are predicted by (C+D)/2 d,g,h,k,l,n,o,p are predicted by D 3.5.3 Mode 2: Vertical prediction If A,B,C,D are inside the picture, a,e,i,m are predicted by A, b,f,j,n by B etc. 3.5.4 Mode 3: Diagonal prediction This mode is used only if all A,B,C,D,E,F,G,H,I are inside the picture.

Partly because of these advances, the needs of the users of weather services have simultaneously diversified to encompass “environmental” prediction products such as air quality and hydrological predictions. (...) Two closely related initiatives, the WWRP Polar Prediction Project and the WCRP Polar Climate Predictability Initiative (PCPI), aim to contribute to GIPPS. (...) The Subseasonal to Seasonal Prediction project Forecasting for the sub-seasonal time range has so far received much less attention than medium range and seasonal prediction as it has long been considered a “predictability desert.”

The MBTYPE field indicates whether there is direct-mode prediction, forward prediction, backward prediction, or bi-directional prediction. (...) Backward prediction means prediction from the same macroblock in the next lower layer (zero motion vector). (...) Forward prediction denotes prediction from the corresponding macroblock in the next lower layer (zero motion vector).
