+ * packets, inserted by the AV core decoder/digitizer/slicer in the
+ * horizontal blanking region of the VBI lines, in "raw" mode as far as
+ * the Encoder is concerned. We don't ever tell the Encoder itself
+ * to provide sliced VBI. (AV Core: sliced mode - Encoder: raw mode)
+ *
+ * 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

+ * 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
