[Mp4-tech] Reference Lists

[Nitthilan Kannappan Jayakodi]

Dear experts,
      In the h.264 standard, two reference lists(0 and 1) are used. Why
      is this so? because,
1) the reference pictures are present in both the lists
2) the forward , backward and bi-prediction can be done from a single
list
further if u say that the two reference lists the ordering is such that
the neighbouring pictures( the immediate fw. and backward picture) may
have a less reference index ( mostly zero) and thus produce compression,
why to repeat the pictures in the two lists.
   We can have List(1) for all backward pictures and List(0) for all fw.
   pictures.
Is there any special reason for this kind of arrangement? Pls. clarify.
expecting ur reply,
K.J.Nitthilan
