Abstract:
A method comprising:providing an information signal;sampling and quantizing the information signal to obtain representation symbols;encoding the representation symbols to obtain code words, including assigning a code word value to each different representation symbol value, in accordance with a predetermined coding technique, some of the code words having different lengths than other code words;determining the number of different representation symbol values in the coded information signal block;generating a first type of coded information signal block, containing a first type of decoding information, if the number of different values of the symbols is greater than or equal to a predetermined number, and generating a second different type of coded information signal block, containing a second different type of decoding information, if the number of different values of the symbols is smaller than the predetermined number, the coded blocks containing the encoded representation symbols of the information signal, the decoding information indicating which representation symbol value or values each code word value represents, the decoding information depending on other information about the symbols or code words than that on which the type of decoding information depends; andtransmitting the first or second types of coded block.
