摘要： It is a purpose of the present invention to provide a video encoding apparatus, a video decoding apparatus, a video encoding method, a video decoding method, and a computer program, which allow adaptive filter coefficients to be used with a reduced amount of coding. A video encoding apparatus AA selects a suitable coefficient from among multiple kinds of interpolation filter coefficients determined beforehand by means of a component external to the video encoding apparatus AA. Subsequently, the video encoding apparatus AA records identification information uniquely defined for the selected interpolation filter coefficient in control information for each slice. Furthermore, the video encoding apparatus AA uses the interpolation filter coefficient thus selected to generate encoded data c including the identification information uniquely defined for the interpolation filter coefficient thus selected.

摘要： A feature amount extracting unit extracts a block distortion degree of an evaluated video y relative to an original video x, a PSNR overall temporal fluctuation degree, and a PSNR local temporal fluctuation degree as feature amounts. A weighted sum calculating unit calculates a weighted sum of these feature amounts, and calculates an objective video quality index. Frame rate detecting unit detects frame rate of the evaluated video y. A correcting unit corrects the objective video quality index based on the frame rate detected by the frame rate detecting unit. An objective evaluation index-subjective video quality mapping unit applies the corrected objective video quality index Qobj to a correlation between an objective video quality index and a subjective video quality given in advance, thereby deriving a subjective video quality estimated value DMOS.

摘要： In the present invention, by performing a control so that the I-coding modes of the encoders of a plurality of respective channels do not overlap each other, the amount of generated encoded information for the total system can be reduced without reducing the allowed amount of information of each encoder. Further, the bit rate Ri (i=1, 2, 3, . . . ) which minimizes the mean square error (E) is determined, on condition that the total bit rate (R) is constant, and informed the encoder. The encoder encodes a video signal at the specified bit rate. This allows the total performance of the plurality of encoders to be increased under a predetermined total bit rate.
