Subtitles

There are a lot of different types of external subtitle files. Most contain textual data. That is the subtitle
and a timestamp at which this subtitles is to be shown. Some of these allow for additional formatting, others 
don't.

• SubRip
• SubViewer?
• SAMI?
• MicroDVD?
• VPlayer?
• Sub Script Alpha?
• JacoSub?
• MPsub?

There are also subtitles which are essentially pictures instead of text. These kind of subtitles are used in DVDs, VCDs and the external VobSub? files.

• DVD subtitles?
• DVB sutitles?
• Vobsub?
• CVD?
• OGT?

There are also some fileformats to which you can add subtitles. These include:

• MOV?
• MP4?
• OGM?
• Matroska?

It is not easy to stream subtitles. DVB or DVD subtitles encapsulated in a TS MPEG stream is your best bet.
