42 TTUSB_HWSECTIONS:
43 the DSP supports filtering in hardware, however, since the "muxstream"
44 is a bit braindead (no matching channel masks or no matching filter mask),
45 we won't support this - yet. it doesn't event support negative filters,
46 so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
47 parse TS data. USB bandwidth will be a problem when having large
48 datastreams, especially for dvb-net, but hey, that's not my problem.
49
50 TTUSB_DISEQC, TTUSB_TONE:
51 let the STC do the diseqc/tone stuff. this isn't supported at least with
52 my TTUSB, so let it undef'd unless you want to implement another
53 frontend. never tested.
54
55 DEBUG:
56 define it to > 3 for really hardcore debugging. you probably don't want
57 this unless the device doesn't load at all. > 2 for bandwidth statistics.
