| * horizontal blanking region of the VBI lines, in "raw" mode as far as |

| * |
| * We then process the ancillary data ourselves to send the sliced data |
| * to the user application directly or build up MPEG-2 private stream 1 |
| * packets to splice into (only!) MPEG-2 PS streams for the user app. |
| * |
| * (That's how ivtv essentially does it.) |
| * |
| * The Encoder should be able to extract certain sliced VBI data for |
| * us and provide it in a separate stream or splice it into any type of |
| * MPEG PS or TS stream, but this isn't implemented yet. |

| * Number of "raw" VBI samples per horizontal line we tell the Encoder to |

| * |
| * (1/Fh)*(2*Fp) = Samples/line |
| * = 4 bytes EAV + Anc data in hblank + 4 bytes SAV + active samples |
| * |
| * Sliced VBI data is sent as ancillary data during horizontal blanking |
| * Raw VBI is sent as active video samples during vertcal blanking |
