Is the source DVB-T? If you have files containing unencrypted recordings of the satellite broadcasts with the subtitles that you want you can probably extract them. You could try Cypheros TSDoctor to see if it works for what you want to do. It has a free trial so you can see what it can do before you buy. https://www.cypheros.de/eng/tsdoc4_specs.html#Specs contains information about what the software can process.

The way I do it with my Beyonwiz PVR, its DVB-T and unencoded, just drop the file into mkvtoolnix to make a MKV file, which I save onto my NAS. If there are any subs and I want to extract them I use Inviska MKV Extract.

lol, benhouli asks about DVB-S or DVB-C, and you both write on DVB-T. Can be similar but not always.

@benhouli more info is needed: what satellite, what means "get": display on your tv (> read tv manual) or extract from the stream, etc.

[lollo]

Does not matter if DVB-S, DVB-T or DVB-C, the transport stream format is the same.

Just use TSDoctor as suggested.

Apparently, I had a brief mental lapse but as lollo wrote, TS-Doctor works for transport streams from satellite broadcasts too, as long as the recording is not encrypted.

The USA uses ATSC 1.0/ATSC 3.0 for free terrestrial TV broadcasts and a similar QAM format for cable. From the small amount of testing I have done, TS-Doctor works for their transport streams too (as long as the recordings are not encrypted) except for extracting subtitles/closed captions.

i think that the recording is encrypted , but how do i check ?

Transfer a copy of a recording that has subtitles that you want to save to a USB flash drive. Try to play the file with your computer using VLC, which plays most types of video. If the file plays, then it isn't encrypted. If it doesn't play, try to open the file using MediaInfo. If MediInfo reports that the file is encrypted, then you have your answer.

i am missing here something , i watch in 2 ways now ...

1.Satellite receiver via satellite cable
2.Xiaomi TV Box S 2nd Gen via internet....

from the satellite receiver i believe it's encrypted for sure...
from the xiaomi tv box streamer , i don't know where the satellite app save the recordings....

You need to copy your recordings to a PC to extract subtitles using (free) ffmpeg and/or MKVToolnix. Like usually_quiet wrote, if the file is encrypted then it won't be playable outside your sat box. Such encrypted recording is impossible to crack. The only option would be to re-record it on PC.

i have a capture card ... but it's record hard sub and not seperate files the recording files are mp4 , don't know if it's matter

If you don't have an unencrypted original recording from the satellite box then you can't easily extract the subtitles.

I have not used this type of software but I think some apps exist that can process the hard subs using optical character recognition to generate text. However, the accuracy of the results is unlikely to be perfect.

[noemi7]

If I'm right mp4 container doesn't support PGS subtitles hence it makes them hardcoded thus even more difficult to OCR. Subtitle Edit is free and one of the best to check in this matter.

To make your life easier would be to buy a sat tuner which doesn't encrypt recordings, and catches whole stream into TS container. The question is then if it's possible as some sat cards and CAM module are paired with the tuner/box delivered by the TV service provider.

Read this:

In this case, subtitles can only be provided as hard subs regardless of the container used. Neither HDMI connections nor analog video connections have the ability to provide DVB subtitle streams so it doesn't matter what container benhouli uses to store the output from a capture device.

thank you both for the answers,
by the way , i use an iptv service too , and there the subtitles is hidden till i choose them
i tried to make something via vlc ...
i got this info from mediainfo
can it help me ?

You have a TS file created using VLC's record function. I assume that you have successfully played that TS file. MediaInfo did not report that the file is encrypted. The TS file has DVB subtitles. I'd say that the chances that you can extract the subtitles using the trial version of TS-Doctor are very good (TS-Doctor can also edit TS files if you need to do that.). ...or you can try the other methods suggested to you that use free, open-source software.

Unfortunately, since I don't live in a country that uses DVB, I have no experience with DVB subtitles. Others who responded to this thread probably know more about converting DVB subtitles into some other type of subtitle, such as SRT subtitles or SUB/IDX.

thank you for all the info and helping... i will try ts doctor..

edit : ts doctor still want me to use ocr for the convert... and it's a lot of more to learn how to do it

but it seems to be the only way ? right ?

Unfortunately, it is the only way if you need SRT or other text-based subtitles because DVB subs like DVD subs and Blu-ray subs are graphics-based, not text-based. ...but OCR might work better in this case than with hard subs because the background isn't complex.

If you can use graphics-based subs perhaps someone can suggest the best format and conversion tool for them. Since I work with US closed captions, which are closer to being text-based, I don't know what to recommend.

ok, then now i succeed to save it on srt file , but it's a bit out of sync, seems to be too much work if i want to do it with episode of 11 seasons with 22-23 chapters....

[netmask56]

Do you have Subtitle Edit? Available here under Tools

[noemi7]

Nope, they are also in text format, and more over a DVB-S and DVB-T stream can contain both types. It depends on national or regional standard.

[netmask56]

Here is a subtitle file from my DVB terrestrial tuner after dropping the original TS file into mkvtoolnix to convert to mkv. It also converts the DVB subtitle to SRT in the process. So easily extracted.

Good to know but benhouli only has the graphics-based type available to him in his sample file. Since you know all the pertinent facts about DVB-T, DVB-S, DVB-C, and DVB subtitles you should be able to offer benhouli some useful advice regarding the appropriate tools and subtitle formats to use for converting DVB subs to be more suitable for his use.

I looked at your MediaInfo report. It says "Format: Teletext Subtitle" I'd guess that "Teletext Subtitle" indicates text-based subs. If your sample file's DVB subs are text-based, then they should be easier to convert to SRT format than the graphic-based type. ...or am I misinterpreting the MediaInfo Report that you posted?

The MediaInfo report for benhouli's VLC record sample has the words "Format : DVB Subtitle" and his subs are graphics-based.

[benhouli]

by the way , after i succeed to save the dvbsubtitle to srt file . it's out of sync , and on subtitle workshop it's open like this...

Can you upload the video somewhere so others could take a look at those graphics based subtitles?

Is this acceptable/decent enough? I don't know hebrew so I only compared the characters visually. There will never be 100% accuracy unless you write it by hand.
