s872: the playing time length of the inter-cut playing between P and P' is P to P, the playing content Ac, and the playing position of Ac is P;
s873: adjusting the playing content Ad after the predicted inter-playing position P;
s874: the playing position of Ad is P, the playing time is Pd-P, the playing content Ad is changed into Ad ', the playing position of Ad ' is P ', the playing time is Pd-P,
in this embodiment, the actual playing position P 'of the fixed-point video is calculated according to the following formula'
