Abstract
According to this invention, a field of useful data is split into a number of basic entities, called 'data groups'. Each data group is, in turn, split into smaller basic entities or 'data blocks'. Each resulting data block is inserted in a data packet to be transmitted through a teletext or videotext network. Therefore, an input coupler has two functional parts: a data group generator and a data packet generator.
