Abstract
(EN)
Text data is arranged into groups. A unique code is assigned to each group. The data is encoded so that the codes represent the groups. The groups and their assigned codes (120) are transmitted to a receiver (14) where they are stored as a table (52) correlating each group to its assigned code. After the table is transmitted, the program (128) and the encoded text data (124) are transmitted to the receiver, preferably in synchronism. At the receiver, the data is decoded (50) from the table and displayed (54) as the program is reproduced.

Des données de texte sont disposées en groupes. Un code unique est attribué à chaque groupe. Les données sont codées de façon que les codes représentent les groupes. Les groupes et leurs codes attribués (120) sont transmis à un récepteur (14) dans lequel ils sont mémorisés sous forme de table (52) établissant la corrélation entre chaque groupe et son code attribué. Après la transmission de la table, le programme (128) et les données de texte codées (124) sont transmis au récepteur, de préférence de façon synchronisée. Les données sont décodées (50) à partir de la table, au niveau du récepteur, puis sont affichées (54) simultanément à la reproduction du programme.
