A method for scalable coding of image information, in particular video image information

摘要

A method for scalable coding of image information, in particular video image information, in which:– an input signal (is) with the image information in a first encoding step comprising an entropy coding (ec) in a first coded signal with a plurality of codes (c1, c2,.., cn) is converted, each code (c1, c2,.., cn) is associated with a decoded value,– the first coded signal in a second encoding step (sc), wherein said first coded signal as a function of a desired data rate for the transfer of the image information is compressed, in a second encoded signal is converted,– the codes (c1, c2,.., cn) of the first coded signal in the second encoding step includes be shortened, and each shortened code (v1, v2, v3; v1 '', v2'', v3, v4 '') a representative (r1, r2, r3; r1'', r2 '', r3'', r4 '') is associated with.
