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 | |
9aaeded7 | 43 | parse TS data. USB bandwidth will be a problem when having large |
1da177e4 LT |
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. | |
