| 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. |
