A trellis encoder for trellis encoding a dual transmission stream. A first multiplexer selectively outputs one of a predetermined first bit of the dual transmission stream and a value stored in a first memory according to an external control signal. A first adder adds the value output from the first multiplexer to the value stored in the first memory, outputs the added value, and stores the added value in the first memory. A second multiplexer selectively outputs one of a predetermined second bit of the dual transmission stream and a value stored in a second memory according to the external control signal. A second adder adds the value output from the second multiplexer to the value stored in the second memory and stores the added value in a third memory. Thus, an initialization is effectively performed before trellis encoding is performed.

L'invention concerne un codeur en treillis pour coder en treillis un double flux de transmission. Un premier multiplexeur génère sélectivement un premier bit prédéterminé du double flux de transmission ou une valeur stockée dans une première mémoire, conformément à un signal de commande externe. Un premier additionneur ajoute la valeur générée par le premier multiplexeur à la valeur stockée dans la première mémoire, génère la valeur ajoutée et stocke la valeur ajoutée dans la première mémoire. Un second multiplexeur génère sélectivement un second bit prédéterminé du double flux de transmission ou une valeur stockée dans une seconde mémoire, conformément au signal de commande externe. Un second additionneur ajoute la valeur émise par le second multiplexeur à la valeur stockée dans la seconde mémoire et stocke la valeur ajoutée dans une troisième mémoire. On effectue ainsi efficacement une initialisation avant la réalisation d'un codage en treillis.
