An apparatus, method and data structure for generating at least one table in a broadcast environment, are provided. The apparatus includes a generator to generate an event information table (EIT) and an extended text table (ETT). The ETT has program guide information for an n-hour span and has a transmission interval. The ETT has a transmission interval and program description information according to the EIT. The transmission interval of the EIT is shorter than the transmission interval of the ETT. 120-. (canceled)21. A method to set repetition intervals for tables to be transmitted as part of a digital television (DTV) transport stream , the method comprising:{'b': 0', '1', '2', '3', '0', '1, 'setting repetition intervals for a sequence of event information tables EIT, EIT, EIT, and EIT containing program information covering different time spans, wherein the repetition interval of the EIT is less than the repetition interval of the EIT;'}{'b': 0', '1', '2', '3', '0', '1', '2', '3', '3', '0', '1, 'setting repetition intervals for a sequence of extended text tables ETT, ETT, EIT, and ETT containing program description information associated with the EIT, EIT, EIT, and EIT, respectively, wherein the repetition interval of the ETT is greater than a sum of the repetition interval of the EIT and the repetition interval of the EIT;'}{'b': 0', '0, 'setting a repetition interval for a master guide table (MGT), wherein the repetition interval of the MGT is less than a sum of the repetition interval of the EIT and the repetition interval of the ETT; and'}broadcasting the DTV transport stream having the EITs and the ETTs therein to receiving devices.22. The method of claim 21 , wherein each of the different time spans is a 3 hour time span.23. The method of claim 21 , wherein the program information includes program guide information having at least program duration time information and program start time information.240. The method of claim 21 , wherein the repetition ...
