Convenient teletranscription method based on EIT in video digital recorder

摘要

When a televiewer watches digital TV (DTV), one may encounter some program previews. If the televiewer wants to transcribe the main program, one has to search it and pre-engage for a transcription by using electronic program guide (EPG) after memorizing the date, time, title, channel and so on. This happens because program and system information protocol (PSIP), contains program information using EPG in DTV, is not served program information in the case of previews. Therefore, we propose a method and algorithm to provide program information for teletranscription without any change of the PSIP standard and implement them in DTV. This paper will introduce a convenient method to transcribe TV programs by taking advantage of event information table (EIT), among the standards of PSIP, which contains information like title and on-air time. Televiewer can transcribe actual program of preview easily using proposed method, while preview is broadcasting.
