摘要

The invention describes a method for measuring the audio description time in the Transport Flows (TS) of Digital Terrestrial Television (DTT), which comprises: obtaining the different TS from the DTT; extract information about each channel from the Event Information Tables (EIT) and from the service information tables (SI) included in said TS; extract additional information on each channel from an Electronic Program Guide (EPG) obtained from a Web Service; generate an Electronic Enriched Program Guide (EEPG) by combining the information extracted from the EIT and the additional information extracted from the EPG; separating the audio streams of each program from each channel transported by said TS according to the programming of each channel obtained from the EEPG; and analyze the audio flows corresponding to each program of each channel to obtain the audio description time.
