• pid=[integer]: The packer identifier (PID) of the caption stream you wish to play

• type=[subtitle_type]: The encoding standard of the subtitles. This value can be one of the following:

o CEA708: If the CEA-708 standard is not present, the subtitle_type will default to CEA-608 (if it is

present).

o CEA608

o DVB

• lang=[language]: A code that determines the preferred language of the subtitles (e.g. eng, spa). The language

codes are specified in the ISO 639-2 standard.

• service=[integer]: The preferred service number of the caption stream

Example:

"pid=0, type=Cea708, lang=eng service=1;;"

Note the following rules when matching templates to video, audio, or caption stream descriptions:

• For a template to match a stream description, every pattern within the template must match.

• The first listed template to match the stream description (if any) will be used.

• An empty template string will match any stream description.
