FIELD: engineering of systems for encoding digital video signals, in particular, indication of values of quantization parameters in video encoding system.
SUBSTANCE: method and device for encoding a digital video series are claimed, where indication of quantization parameter is given out in encoded bit stream for use during decoding. Indication of information concerning the quantization parameter is ensured by insertion of SQP value - series level quantization parameter value. In particular, instead of encoding absolute values of parameters of quantization of image/section, indication of difference ΔQP between series level quantization parameter SQP and QP of image/section, is given out.
EFFECT: increased efficiency when encoding digital video signals and reduced speed of data transmission in bits.
