| 2 | * Programming the mspx4xx sound processor family |
| 3 | * |
| 4 | * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org> |
| 5 | * |
| 6 | * what works and what doesn't: |
| 7 | * |
| 8 | * AM-Mono |
| 9 | * Support for Hauppauge cards added (decoding handled by tuner) added by |
| 10 | * Frederic Crozat <fcrozat@mail.dotcom.fr> |
| 11 | * |
| 12 | * FM-Mono |
| 13 | * should work. The stereo modes are backward compatible to FM-mono, |
| 14 | * therefore FM-Mono should be allways available. |
| 15 | * |
| 16 | * FM-Stereo (B/G, used in germany) |
| 17 | * should work, with autodetect |
| 18 | * |
| 19 | * FM-Stereo (satellite) |
| 20 | * should work, no autodetect (i.e. default is mono, but you can |
| 21 | * switch to stereo -- untested) |
| 22 | * |
| 23 | * NICAM (B/G, L , used in UK, Scandinavia, Spain and France) |
| 24 | * should work, with autodetect. Support for NICAM was added by |
| 25 | * Pekka Pietikainen <pp@netppl.fi> |
| 26 | * |
| 27 | * TODO: |
| 28 | * - better SAT support |
| 29 | * |
