I do have the stk1160 chip datasheet. However, it's not publicly available and I'm not sure I should disclose it (although syntek never advise me against it). In additio, the datasheet is not very verbose and the information is scarce and often incomplete. > And I wonder if the device can support VBI at all. > Apparently it does: at least there's a flag to "enable" VBI mode. > You are better off choosing devices that already have VBI support: the > em28xx supports it, so do bt8xx, cx18 and ivtv. > I agree with this. I don't have any VBI source so there's no way I can work on this (not to mention it's not something lots of users need). -- Ezequiel García, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
