- * Number of "raw" VBI samples per horizontal line we tell the Encoder to
- * grab from the decoder/digitizer/slicer output for raw or sliced VBI.
- * It depends on the pixel clock and the horiz rate:
- *
- * (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
- *
- *  We use a  BT.656 pxiel clock of 13.5 MHz and a BT.656 active line
- *  length of 720 pixels @ 4:2:2 sampling.  Thus...
- *
- *  For systems that use a 15.734 kHz horizontal rate, such as
- *  NTSC-M, PAL-M, PAL-60, and other 60 Hz/525 line systems, we have:
- *
- *  (1/15.734 kHz) * 2 * 13.5 MHz = 1716 samples/line =
- *  4 bytes SAV + 268 bytes anc data + 4 bytes SAV + 1440 active samples
- *
- *  For systems that use a 15.625 kHz horizontal rate, such as
- *  PAL-B/G/H, PAL-I, SECAM-L and other 50 Hz/625 line systems, we have:
- *
- *  (1/15.625 kHz) * 2 * 13.5 MHz = 1728 samples/line =
- *  4 bytes SAV + 280 bytes anc data + 4 bytes SAV + 1440 active samples
