From: "thomas schorpp" <t.schorpp@xxxxxx> > in 429 the framing shows only outer r-s fec. > the latest 468 standard says we HAVE inner fec(!) No, it just defines a way to indicate an inner FEC method through the DVB Service Information. But since there is no inner FEC method defined for the DVB-C transmission standard, the only possible value you can use is: > Table 35: Inner FEC scheme > 1111 no conv. coding > > i'll implement this in the driver until weekend What do you want to implement? I suggest you start by examining the DVB Service Information you receive (try e.g. dvbsnoop). I'm 99.99% sure you'll find "no conv. coding" indicated in your cable delivery system descriptors. > -if- someone gets me programming registers and values or a full > datasheet, theres no on the web, or i try using the ves1x93 data... The VES1820 is a demodulator for the DVB-C standard and thus has no inner FEC (Viterbi) decoder. The circuits for this are simply not there, period. Stop thinking about inner FEC, it is definitely _not_ the problem you are facing. Regards, -- Robert Schlabbach e-mail: robert_s@xxxxxxx Berlin, Germany
