Abstract

See full text

In a video encoding control method of the present invention, each picture is encoded in units of encoding-order picture groups such as GOPs, and when CPB underflow has occurred, an encoding parameter such as a quantization parameter and filter strength of a pre-filter is changed in such a manner that a generated bit rate is reduced, and an encoding-order picture group that is being encoded is re-encoded from its first picture using the changed encoding parameter.
