Extract subtítles SRT from a TS DVB broadcast

[sinectar]

Hello. I would like to know how I could Extract subtítles SRT from a TS HD satellite broadcast. I use Linux Mint 15.

When I selected TS>SRT, Avidemux showed the following error missage:

"Crash

Thank you very much.

If nobody answers, you can do it with ProjectX.

Sooo tempting to take the mickey out of zakk!
Oh hell why not  ----  after all  "nobody" did answer first!.
Now I will brace myself for the wrath of zakk.

@ sinectar
Project X is a good suggestion from zakk as long as the broad cast stream is not AVC encoded.
The subtitles are overlayed bit mapped images that need some OCR conversion to SRT.
Could try TSmuxer to demux the stream and extract the subtitle tracks, then maybe subrip for OCRing these subtitle tracks.

Many thanks for your help, zakk and AQUAR! I will try with these other programs recommended by you.

ProjectX can also extract subs from an AVC stream.
