摘要： The prediction error energy in inter-frame prediction with motion compensation is reduced and the coding efficiency is improved. A video encoding method using fractional-accuracy motion compensation includes: a step of generating multiple weighted filter coefficients from multiple interpolation filter sets using weight parameters which designate weight values of interpolation filter coefficients; a step of selecting weighted filter coefficients which minimize prediction error energy in the fractional-accuracy motion compensation from among the weighted filter coefficients; a step of interpolating fractional-accuracy pixels for a reference picture by application of an interpolation filter with the selected weighted filter coefficients and encoding an input picture with the fractional-accuracy motion compensation; and a step of encoding the weight parameters used for generating the selected weighted filter coefficients and the interpolation filter coefficients and adding encoded weight parameters and encoded interpolation filter coefficients to an encoded bitstream.

摘要： 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.

摘要： A method and apparatus for deciding an encoding mode are disclosed. The encoding mode decision apparatus comprises a temporal complexity calculator to calculate a temporal complexity of a macroblock and a mode decider to elect the encoding mode utilizing the temporal complexity. The disclosure calculates the temporal and spatial complexes for the macroblocks more accurately as well as elects the optimal encoding mode using the same resulting in a reduction of the calculation complexity when applying the rate-distortion technique along with an improvement of its processing speed.
