Question on video device in /dev for S460 card cx88

[Peter Brouwer]

Hello

Quick question regarding video devices that show up when using a cx88 base S460
(tevii) DVB-S2 card.

I see two devices in /dev
/dev/video0 and /dev/vbi0 related to the cx88 based dvb-s2 card.
What are those devices, is the video0 the video out of the card after the
demuxer? If so, should that device not show up in /dev/dvb/adapterN ??

What is the /dev/vbi0 device?

Regards
Peter
