Abstract
Apparatus for decoding information which has been coded with a tree code including a tree decoder. The tree decoder includes a tree input port at which a token enters the tree decoder, a plurality of tree output ports from one of which the token exits the tree decoder and a plurality of nodes forming a tree connected between the tree input port and the tree output ports. Each of the nodes includes an token input port, two token output ports, a code input port and apparatus for operating the node in a first mode wherein the token passes from the token input port to one of the token output ports in response to the code input and in a second mode wherein the token passes from the token input port to one of the output token ports independent of the code output.
