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.

Apparatus for decoding information which has been coded with a tree code comprising:
- a tree decoder including:
- 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 comprising:
- an token input port;
- two token output ports;
- a code input port;
- and
- means 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 a second mode wherein the token passes from the input port to one of the output ports independent of the code output.
