Abstract:
1. A method in a video coding or decoding process implemented in a computer device wherein a number of blocks of residual picture data respectively stored in a number of first data arrays in a memory of the computer device represent at least a part of a video picture to be coded or decoded, the method comprising: calculating DC coefficients respectively associated with the blocks and inserting the DC coefficients in a second data array in a block associative order; classifying each of the blocks as skipped in response to an associated DC coefficient being lower than a predefined threshold, and non-skipped in response to the associated DC coefficient being higher than the predefined threshold; generating a bit mask containing 1-bits in positions corresponding to positions in the second data array having DC coefficients higher than the predefined threshold, and 0-bits in positions corresponding to positions in the second data array having DC coefficients lower than the predefined threshold; and in response to the bit mask containing 1-bits,
