Patent ID: 8898706

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 EIT0, EIT1, EIT2, and EIT3 containing program information covering different time spans, wherein the repetition interval of the EIT0 is less than the repetition interval of the EIT1; setting repetition intervals for a sequence of extended text tables ETT0, ETT1, ETT2, and ETT3 containing program description information associated with the EIT0, EIT1, EIT2, and EIT3, respectively, wherein the repetition interval of the ETT3 is greater than a sum of the repetition interval of the EIT0 and the repetition interval of the EIT1, wherein the repetition interval of the ETT2 is equal to the repetition interval of the EIT2; setting a repetition interval for a Terrestrial Virtual Channel Table (TVCT), wherein the repetition interval of the TVCT is less than the repetition interval of the ETT-0; and broadcasting the DTV transport stream having the EITs, the TVCT and the ETTs therein to receiving devices.
