1. one kind is used for encoded video signal and carries out the video encoder of encoding and controlling according to the occupancy of virtual bumper, measures and sends to the sign indicating number amount of exporting the destination according to the sign indicating number that generates by coding and determine described occupancy, and this video encoder comprises:

  • Logging mode is determined device, is used to determine whether the last chapters and sections and the seamless link between one chapters and sections of back that comprise in vision signal be feasible, and according to determining that the result is provided with the initial value of the occupancy of virtual bumper;

    The occupancy updating device is used for upgrading the occupancy of virtual bumper when each execution is encoded;

    Best occupancy calculation element is used for calculating predetermined best occupancy according to the occupancy that has upgraded of virtual bumper;

    The object code device for calculating is used for calculating predetermined object code amount according to the vision signal of back one chapters and sections;

    The object code amount adjusting apparatus is used to adjust the object code amount, makes the occupancy of virtual bumper and the summation of object code amount be no more than best occupancy;

    WithCode device is used for carrying out coding according to adjusted object code amount.
