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