Abstract: A method and system for replacing at least one item in a source string compiled at a TV set-top box for conveying via a TV communication infrastructure. A TV communication gateway receives the source string from the TV set-top box, parses the source string and identifies at least one item that requires replacing. Such item may be incorrectly spelled or the TV communication gateway may run an application that translates the source string to a foreign language. For each item that requires replacing, the TV communication gateway determines at least one replacement item, compiles data which it forwards to the TV set-top box. In the case of a spell-check program, the data may be an XML list including for each incorrectly spelled item a list of alternatives. The list of replacement items relating to the selected item is displayed, allowing a user to select a desired replacement item.
