375 * A note about "sliced" VBI data as implemented in this driver:
377 * Currently we collect the sliced VBI in the form of Ancillary Data
378 * packets, inserted by the AV core decoder/digitizer/slicer in the
379 * horizontal blanking region of the VBI lines, in "raw" mode as far as
380 * the Encoder is concerned. We don't ever tell the Encoder itself
381 * to provide sliced VBI. (AV Core: sliced mode - Encoder: raw mode)
383 * We then process the ancillary data ourselves to send the sliced data
384 * to the user application directly or build up MPEG-2 private stream 1
385 * packets to splice into (only!) MPEG-2 PS streams for the user app.
387 * (That's how ivtv essentially does it.)
389 * The Encoder should be able to extract certain sliced VBI data for
390 * us and provide it in a separate stream or splice it into any type of
391 * MPEG PS or TS stream, but this isn't implemented yet.
395 * Number of "raw" VBI samples per horizontal line we tell the Encoder to
396 * grab from the decoder/digitizer/slicer output for raw or sliced VBI.
397 * It depends on the pixel clock and the horiz rate:
399 * (1/Fh)*(2*Fp) = Samples/line
400 * = 4 bytes EAV + Anc data in hblank + 4 bytes SAV + active samples
402 * Sliced VBI data is sent as ancillary data during horizontal blanking
403 * Raw VBI is sent as active video samples during vertcal blanking
405 * We use a BT.656 pxiel clock of 13.5 MHz and a BT.656 active line
406 * length of 720 pixels @ 4:2:2 sampling. Thus...
408 * For systems that use a 15.734 kHz horizontal rate, such as
409 * NTSC-M, PAL-M, PAL-60, and other 60 Hz/525 line systems, we have:
411 * (1/15.734 kHz) * 2 * 13.5 MHz = 1716 samples/line =
412 * 4 bytes SAV + 268 bytes anc data + 4 bytes SAV + 1440 active samples
414 * For systems that use a 15.625 kHz horizontal rate, such as
415 * PAL-B/G/H, PAL-I, SECAM-L and other 50 Hz/625 line systems, we have:
417 * (1/15.625 kHz) * 2 * 13.5 MHz = 1728 samples/line =
