us-cable SAP interference

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I have an AverMedia TV/FM98 (dbx stereo) that is giving me some wierd
problems, but not terminal. It seems to picking up some SAP on a few
channels. I found the following...

http://tallyho.bc.nu/~steve/nicam.html
Since BTSC's SAP doesn't conflict with main stereo audio, many U.S.
broadcasters and cable operators use it for services other than a second
language -- one can often find either the BBC World Service or the National
Weather Service's local radio transmissions on SAP in many areas. 

I do sometimes get the Weather Service. On 1 channel I get nothing.
On another I get a recording about there not being SAP available
and to consult my manual about changing the TV settings and last night
I found a descriptive program running whilst watching the Simpsons
(in that it described the scenes when nobody was talking, a service
for the blind I believe). If I choose LANG1 in any of the viewers,
it fixes it (rather than choosing LANG1 to hear these services).

On the 1 channel where I got nothing, I can get audio on LANG1 if
I changed the card id to 6 rather than the auto-detected 41. So I 
added the avermedia_auio_hook to the bttv-cards.c entry and I can
let the bttv module auto-select the card device and at least get
audio on all channels now.

Also, I am unable to get the driver to detect the msp3400 chip.
i2c says it is registered, but it never gets found when searching
for it. Though I cannot guarantee that I actually *HAVE* and msp34xx
chip on the card without pulling it too see, but it used to work
in the 2.2 series with the msp3400 driver.

And a little nod to the developers (though should be no surprise)
When I added a new HD to my ATA/100 interface, which shares the IRQ
with the TV tuner, the card has stopped working in Windows. The
bugger of this is that I can't use any of the Windows tools to look
for the register information mentioned in the Sound-FAQ to try
to be able to build a new bttv-cards entry :(

And speaking of the Sound-FAQ, the bTV program has moved to
borgtech.org/btv/

Thanx
