Abstract
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 are transmitted to a receiver where they are stored as a table correlating each group to its assigned code. After the table is transmitted, the program and the encoded text data are transmitted to the receiver, preferably in synchronism. At the receiver, the data is decoded from the table and displayed as the program is reproduced.
