1. A method for decoding a picture from a bit stream, the method comprising:
decoding a syntax element from the bit stream;
determining, based on the syntax element, a maximum allowed number of merge candidates for a merge candidate list for all coding units in a slice region in the picture;
decoding a merge candidate index for a coding unit in the slice region from the bit stream, wherein one less than the maximum allowed number of merge candidates is used as a maximum codeword size for truncated unary decoding of the merge candidate index;
constructing the merge candidate list for the coding unit wherein the merge candidate list comprises the maximum allowed number of merge candidates; and
reconstructing the coding unit using the merge candidate list for the coding unit and the merge candidate index for the coding unit.
