JCTVC-J0366 Cross-check of J0218 on Bi-pred merge restriction for small PUs [P. Onno (Canon)] [late]
JCTVC-J0166 An experimental comparison of memory bandwidth between P and B-slice coding [T. Chujoh (Toshiba)]

An experimental comparison of memory bandwidth between P and B-Slice coding for low delay configuration is reported. By using the measurement module of memory bandwidth that has been developed by the previous AHG of reference memory compression and has been distributed to previous CE of motion compensation, the numerical results of memory bandwidth analysis is shown. As experimental results, the memory bandwidth increase of B-slice compared to P-slice is reportedly an average of 41% and a maximum of 70%. The contributor suggested that these results should be considered in profile/level discussions.

LB had about 4–5% improvement in compression relative to LP, but with about twice the memory bandwidth.
