TV Captures

We capture TV programs with the PCI version of ATI HD 650 PCI Digital and Analog TV tuner. We install this card in a Windows XP desktop, and we use the accompanying application called ATI Crystal Media Center to watch and capture TV. One of our goal is to extract the closed captions into timstamped text files. This can be done as follows. We first capture a TV program using the default recording profile Best in the Crystal, which results in an mpg file that contains a video, an audio, and an CC tracks. The resulting mpg file can be played by the VLC player but not by the Windows media player nor QuickTime. We then use an open source software called ccextractor to separate the CC text from this mpg file. ccextractor comes with a Windows GUI, but can also be run in command line as ccextractor -out=srt my.mpg. This command creates an srt file that contains close captions with timestamps.

We have put several sample .mpg and .srt files online at our web server. Each of these capture is about 50 min long, and they were captured from an over-the-air digital TV station.
