摘要

The Invention relates to a method for Measuring the time of audio description in the Transport Stream (TS) of the Terrestrial Digital Television (TDT),That includes: obtain the different ts of DTT; extract information on each Channel of the Event Information Tables (EIT) and the tables of Service information (si) included in diChos TS; extracting additional information on each Channel of an Electronic Programme Guide (EPG) obtained from a Web Service; Generating an Electronic Programme Guide (eepg) enriched byCombination of information extracted from the EIT and the additional information extracted from the EPG; separate audio Streams of each Program each Channel carried by these TS in terms ofEach Channel of the eepg obtained; and analyze audio streams corresponding to each Program each channel to obtain the time of audio description.
