An improved predictive encoder where the leak signal is a function of the buffer fullness of the encoder. More specifically, the signals stored in the encoder output buffer are further encoded based on the fullness of the buffer, and information about this further encoding is used in determining the leak factor level. In accordance with another improvement, this leak factor level is not constrained to granularity that is imposed by the decoder hardware. Removal of the constraint is accomplished by cycling through a sequence of permissible leak levels that averages at the desired level.

A method for combining a first encoded video signal and a second encoded video signal, each of which was created by developing a displaced frame difference image signal from a prediction of an applied image signal multiplied by leak factor and from an actual applied image signal, by encoding the displaced frame difference image signal, and by transmitting the encoded signal and the leak factor, comprising the steps of: forcing each of the encoded video signals to have a preselected leak factor at least some of the time; splicing-in the second encoded video signal into the first encoded video signal, to thereby replace the first encoded video signal, at a point in the second encoded video signal where the leak factor of the second encoded video signal is at said preselected value.
