Claim Text:
1. A moving picture decoding method for decoding a coded image, the method comprising: decoding a coded first portion of a first binary signal through context-adaptive arithmetic decoding; and decoding a coded second portion of the first binary signal through bypass arithmetic decoding using a fixed probability, wherein a variable probability is not used in the bypass arithmetic decoding, the first portion of the first binary signal is composed of a head bit of the first binary signal, the second portion of the first binary signal is composed of one or more remaining bits of the first binary signal, the first binary signal corresponding to a value of a first parameter identifying a type of a sample offset process to be applied to a reconstructed image obtained from the coded image, and the moving picture decoding method further comprises converting, using an inverse binarizer, the decoded first binary signal into the value of the first parameter.
