* A note about "sliced" VBI data as implemented in this driver:
|
|
*
|
|
* Currently we collect the sliced VBI in the form of Ancillary Data
|
|
* 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
|
|
* 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 =
|
