Drivers pinnacle mb87j3560 driver. Subtitles I want to convert to some other format, like subrip. On some movies this works, namely ones with 'movtext' subtitles. However some iTunes movies have eia608 subtitles which, when I try to convert them, throw this error: Closed caption Decoder @ 0000014b2b92eec0 Data Ignored since exceeding screen width. QuickTime video supports raw 608 caption data via proprietary closed caption track, which are just EIA-608 byte pairs wrapped in a QuickTime packet container with different IDs for both line 21 fields. These captions can be turned on and off and appear in the same style as TV closed captions, with all the standard formatting (pop-on, roll-up.

In the U.S., TV captioning became required under the Television Decoder Circuitry Act of 1990, which prompted the Electronics Industry Association to create EIA-608, which is now called CEA-608 for the Consumer Electronics Association that succeeded the EIA. Briefly, Section 608 captions are limited to 60 characters per second, with one Latin.

Line 21 VBI captioning is indeed the standard for standard definition, baseband digital and analog video. It's also and the standard for some interchange formats like D10 / IMX, both of which use MPEG-2's 4:2:2 profile to encode a 720x512 image for NTSC, which includes all VBI data (CC and VITC etc).
However, in the compressed domain, an end user would be unlikely to see captions in this form. Quite frequently the 608 (or 708) data packets are stored in the MPEG-2 user data, or as H.264 SEI messages. ATSC A/53 defines both methods.
As an aside, things are a bit different in the HD world. Baseband HD video is usually transported over HD-SDI. In this scenario, captions and other metadata are stored in the vertical ancillary (VANC) data. This VANC data can be partially (or sometimes completely) retained when capturing baseband HD-SDI into a file. However, it's more common for captions to instead be extracted from the VANC, and inserted into MPEG-2 user data, H.264 SEI messages, or a standalone caption file during capture.
Most of that is fairly off-topic, but I find captions interesting (and endlessly frustrating).
