[linux-dvb] Re: NOVA-CI and access the CAM directly

["frankta" <frankta@263.net>]

Thanks to Michael.It seems that there is no extra logic or firmware on the NOVA-CI board.It is possible to patch the linux driver to support the NOVA-CI and access the CAM directly.The only thing is where to get the CAM interface chip's datasheet.I think it's the same as the one on the CI module card for the full functional DVB-s card.Does anybody have this material?
