Patent ID: 7836469

Claim:
A method to set repetition intervals for tables to be transmitted as part of a digital television (DTV) transport stream, the method comprising: setting repetition intervals for a sequence of event information tables EIT 0 , EIT 1 , EIT 2 , and EIT 3 containing program information covering different time spans, wherein the repetition interval of the EIT 0 is less than the repetition interval of the EIT 1 ; setting repetition intervals for a sequence of extended text tables ETT 0 , ETT 1 , ETT 2 , and ETT 3 containing program description information associated with the EIT 0 , EIT 1 , EIT 2 , and EIT 3 , respectively, wherein the repetition interval of the ETT 3 is greater than a sum of the repetition interval of the EIT 0 and the repetition interval of the EIT 1 ; setting repetition intervals for a master guide table (MGT) and a terrestrial virtual channel table (TVCT), wherein the repetition interval of the MGT is less than the repetition interval of the TVCT; and broadcasting the DTV transport stream having the EITs, the MGT, and the TVCT therein to receiving devices.
