Stereokodirovaniya DEVICE, APPARATUS AND METHODS stereokodirovaniya STEREODEKODIROVANIYA And STEREODEKODIROVANIYA

摘要

1. Apparatus stereokodirovaniya, soderzhascheesektsiyu correction, which increases the similarity between the first channel signal and second channel signal by correcting one or both of the first channel signal and second channel signal, a first encoding section that encodes the first channel signal and second channel signal having a large similarity, using a single excitation; and a second coding section that codes information relating to correction korrektsii.2 section. Apparatus stereokodirovaniya according to claim 1, wherein the correcting section corrects one or both of the spatial information contained in the signal of the first channel and the second channel signal; and a second encoding section encodes information related to spatial correction information.3. Apparatus stereokodirovaniya according to claim 2, wherein the spatial information comprises one or both of energy and time delay of the first channel signal and the second kanala.4. stereo coding apparatus according to claim 1, wherein the first encoding section comprises one set of adaptive codebook code knigi.5 constant. stereo coding apparatus according to claim 1, wherein the first encoding section receives the excitation, wherein the sum of the encoding distortion of the first channel signal and second channel signal becomes minimalnoy.6. Apparatus stereokodirovaniya according to claim 1, wherein the correcting section obtains the difference between the spatial information of the first channel signal and spatial information of the second channel signal and removes said difference signal of the first channel signal or the second kanala.7. Stereo coding apparatus according to claim 1,
