418 | * horizontal blanking region of the VBI lines, in "raw" mode as far as | |
419 | * the Encoder is concerned. We don't ever tell the Encoder itself | |
420 | * to provide sliced VBI. (AV Core: sliced mode - Encoder: raw mode) | |
421 | * | |
422 | * We then process the ancillary data ourselves to send the sliced data | |
423 | * to the user application directly or build up MPEG-2 private stream 1 | |
424 | * packets to splice into (only!) MPEG-2 PS streams for the user app. | |
425 | * | |
426 | * (That's how ivtv essentially does it.) | |
427 | * | |
428 | * The Encoder should be able to extract certain sliced VBI data for | |
429 | * us and provide it in a separate stream or splice it into any type of | |
430 | * MPEG PS or TS stream, but this isn't implemented yet. | |
