Decoding a block of quantized transform coefficients, where even parity of the sum of the inverse quantized transform coefficients is set to an odd parity

摘要

A method for decoding a block of quantized transform coefficients, comprising: inversely quantizing the block of quantized transform coefficients to provide transform coefficients aBlock; judge or determine the parity of the sum of the transform coefficients; ycambiar, when it is determined that parity is even, the parity of at least one of the detransformada coefficients, in order to convert an odd parity of the sum of the transform coefficients; yen which, when parity at least one transform coefficient is odd, the parity cambiarestándole 1.
