Hi Thomas, I have some questions. 1) In subsection "3.2. Motion estimation process", "Since F does not exist the motion estimation process consists of matching blocks B+mv0 in R0 with blocks B+mv1 in R1." Does 'B' there probably mean each block in frame F? It was not defined anywhere.
2) Once interpolated reference frame F is obtained, which I understand will spend some bits unless all 16x16 blocks can be skipped, a regular motion estimation on top of frame F with target original input frame is performed? As implied by "The aim is to create a reference frame that is temporally co-located with the current frame being predicted," in "1. Introduction". 3) Lastly, is the interpolated reference frame F only used for B-frame, since frame F itself is anyway motion compensated bi-directionally, i.e. past and future frames (or the other way), R0 and R1, though the current frame can be coded as a P-frame style once F is provided?
