3 | * Programming the mspx4xx sound processor family | |
4 | * | |
5 | * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org> | |
6 | * | |
7 | * what works and what doesn't: | |
8 | * | |
9 | * AM-Mono | |
10 | * Support for Hauppauge cards added (decoding handled by tuner) added by | |
11 | * Frederic Crozat <fcrozat@mail.dotcom.fr> | |
12 | * | |
13 | * FM-Mono | |
14 | * should work. The stereo modes are backward compatible to FM-mono, | |
f8a7647d | 15 | * therefore FM-Mono should be always available. |
53b0a1c6 HV |
16 | * |
17 | * FM-Stereo (B/G, used in germany) | |
18 | * should work, with autodetect | |
19 | * | |
20 | * FM-Stereo (satellite) | |
21 | * should work, no autodetect (i.e. default is mono, but you can | |
22 | * switch to stereo -- untested) | |
23 | * | |
24 | * NICAM (B/G, L , used in UK, Scandinavia, Spain and France) | |
25 | * should work, with autodetect. Support for NICAM was added by | |
26 | * Pekka Pietikainen <pp@netppl.fi> | |
27 | * | |
28 | * TODO: | |
29 | * - better SAT support | |
30 | * | |
31 | * 980623 Thomas Sailer (sailer@ife.ee.ethz.ch) | |
