38 TTUSB_HWSECTIONS:
39 the DSP supports filtering in hardware, however, since the "muxstream"
40 is a bit braindead (no matching channel masks or no matching filter mask),
41 we won't support this - yet. it doesn't event support negative filters,
42 so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
43 parse TS data. USB bandwith will be a problem when having large
44 datastreams, especially for dvb-net, but hey, that's not my problem.
45
46 TTUSB_DISEQC, TTUSB_TONE:
47 let the STC do the diseqc/tone stuff. this isn't supported at least with
48 my TTUSB, so let it undef'd unless you want to implement another
49 frontend. never tested.
50
51 DEBUG:
52 define it to > 3 for really hardcore debugging. you probably don't want
53 this unless the device doesn't load at all. > 2 for bandwidth statistics.
