1. A method of transmitting a video signal, comprising:
transmitting, on a transmission medium, a data stream comprising data associated with a first sequence of source symbols and a second sequence of source symbols, wherein the source symbols of the first and second sequences are related to level values of transform coefficients of a transform coefficient block, and are determined based on a sequence of syntax elements having a value range which is sub-divided into a plurality of disjoint portions by executing operations using a processor, the operations including:
decomposing each syntax element into a corresponding set of source symbols based on a portion of the plurality of disjoint portions associated with the syntax element, such that a combination of values of the source symbols of the set yields a value of the syntax element, and
adapting one or more limits between the plurality of disjoint portions according to one or more previously encoded source symbols.
