METHOD OF DISTRIBUTING AND TRANSCODING VIDEO CONTENT Russian patent published in 2011 - IPC H04N7/30 G06T5/10 

FIELD: information technology.

SUBSTANCE: modified time-based inverse discrete cosine transform is used, where said transform is performed by one operation for multiplying matrices of all coefficients obtained through reverse scanning on all planes of the cube, by single common requantisation matrix, elements of which are formed from elements of dequantisation matrices for time-based inverse discrete cosine transform and MPEG quantisation.

EFFECT: efficient distribution and transcoding of video data for generating video sequences containing Intra-frames from 3D discrete cosine transform video programs owing to time-based modified inverse cosine transform.
