description FIELD: physics, image processing. ^ SUBSTANCE: the invention claims vide image coding method involving coding of video image frames by first video image coding scheme, interlayer filtration for frames coded by the first video image coding scheme, coding of video image frames by second video image coding scheme addressing the frames subjected to interlayer filtration, and generation of bit stream consisting of frames coded by first and second video image coding schemes. First video image coding scheme is Advanced Video Coding (AVC) scheme, second coding scheme is a wavelet coding scheme, and interlayer filtration includes discretisation increase for AVC-coded frames by wavelet filter and subdiscretisation of frames with high discretisation by MPEG filter. ^ EFFECT: improved efficiency of multilayer video image coding. ^ 44 cl, 13 dwg
