EXTENDED TEXT TABLE DISCRIMINATION STRUCTURE OF ELECTRONIC PROGRAM GUIDE FOR DIGITAL TV

摘要

PURPOSE: An ETT(extended text table) discrimination structure of EPG(electronic program guide) for digital TV is provided to discriminate an ETT section in a receiving unit or in a transmission unit without parsing by inputting an event_id to a table_id_extension in the ETT section. CONSTITUTION: A first process(S10) sets an ETT section filter. A second process(S20) detects every ETT section out. A third process(S30) performs a filtering to detect just a corresponding ETT section from the ETT section by using a table_id_extension. A fourth process(S40) performs a parsing of the detected ETT section. A fifth process(S50) records the ETT section parsed in the fourth process(S40) at a text message.
