Abstract
A variable length coding (VLC) method and a variable length coding apparatus for producing variable length coding having a reduced number of arithmetic cycles. The method includes carrying out (a) performing a VLC process and assigning a code to a combination of (Last, Run, Level), (b) subtracting LMAX as the maximum Level corresponding to (Last, Run) from Level to calculate amended Level and thereafter assigning a code to a combination of (Last, Run, amended Level), (c) subtracting a value that is obtained by adding 1 and RMAX as the maximum Run corresponding to (Last, Level) from Run to calculate amended Run and thereafter assigning a code to a combination of (Last, amended Run, Level), and (d) of performing faxed length coding (FLC) assignment in parallel with each other, and includes (e) selecting the code according to predetermined priorities.
