* programming the msp34* sound processor family

|
*
|
|
* (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
|
|
*
|
|
* what works and what doesn't:
|
|
*
|
|
* AM-Mono
|
|
* Support for Hauppauge cards added (decoding handled by tuner) added by
|
|
* Frederic Crozat <fcrozat@mail.dotcom.fr>
|
|
*
|
|
* FM-Mono
|
|
* should work. The stereo modes are backward compatible to FM-mono,
|
|
* therefore FM-Mono should be allways available.
|
|
*
|
|
* FM-Stereo (B/G, used in germany)
|
|
* should work, with autodetect
|
|
*
|
|
* FM-Stereo (satellite)
|
|
* should work, no autodetect (i.e. default is mono, but you can
|
|
* switch to stereo -- untested)
|
|
*
|
|
* NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
|
|
* should work, with autodetect. Support for NICAM was added by
|
|
* Pekka Pietikainen <pp@netppl.fi>
|
|
*
