Adaptive bit allocator

摘要: Improved efficiency in allocating bits to individual ones of a plurality sub-band signals (or amplitude coefficients) is realized by employing so-called template matching technique. A the most likely occur bit allocation patterns and corresponding templates including representations prescribed characteristic that would generate one are stored for later use. Selection pattern use encoding and/or decoding effected accordance with given presently being encoded. In example, power estimate criterion minimum rate distortion criterion.
