If it is using a CI+ plus chip (I heard from someone that it is a CI+ chip inside) : http://www.smardtv.com/index.php?page=ciplus After reading the CI+ specifications, I doubt that it can be supported under Linux with open source support, without a paired decoder hardware or software decoder. A paired open source software decoder seems highly unlikely, as the output of the CI+ module is eventually an encrypted stream which can be descrambled with the relevant keys. The TS is not supposed to be stored on disk, or that's what the whole concept is for CI+ http://www.ci-plus.com/data/ci-plus_overview_v2009-07-06.pdf See pages 7, 8 , 12, 15 It could be possible to pair a software decoder with a key and hence under Windows, but under Linux I would really doubt it, if it happens to be a CI+ chip Regards, Manu -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
