FIELD: information technology.
SUBSTANCE: invention relates to means for indicating possibility of repeated use of frame parameters for decoding vectors. Bit stream is obtained containing a compressed version of the spatial component of the sound field. Spatial component of the sound field is represented by a vector representing an orthogonal spatial axis in the region of spherical harmonics. Bitstream additionally contains an indicator of the need to reuse, from the previous frame, a syntax element indicating a prediction mode, which indicates whether prediction with respect to said vector has been performed.
EFFECT: technical result consists in possibility of reuse of frame parameters for decoding vectors.
