When, picture sequence numbers X is inserted into the head of queue 2, two adjacent with the picture can be placed behind picture sequence numbers X simultaneously
Next serial number X+1, the X-1 of picture may most want to see after the picture that downloading user chooses, to continue downloading user in time
Two frame pictures.
It placed 0,1,2 now in queue 1 ..., this N+1 picture sequence numbers of N placed X, X+ in queue 2
1, X-1, N+1 ..., M these picture sequence numbers, wherein X, X+1, X-1 (for example, as shown in Figure 85,6,4) these three picture sequences
Number sequence chosen operation to trigger sequence by user to adjust, so that their sequence move forward, that is, have occurred sequentially
Adjustment.Here, it is contemplated that after the picture downloading that user chooses, next user may most want to see adjacent with before and after the picture
Two pictures, it is subsequent and at present to facilitate so also the serial number of this two adjacent pictures is moved forward in queue 2
It carries.
Preferential downloading mode has been had begun at this time, i.e., after first being adjusted to picture sequence numbers, next in queue 1
Picture sequence numbers X is placed in middle tail portion, then starts download pictures X, while deleting picture sequence numbers X from the head of queue 2.
